The sun can light your home, power your life, and fuel the rest of the world too — all without being depleted. Sounds like nature’s best energy source, right?

Why is solar energy renewable?

If you’ve read Is Solar Energy Renewable?, you know solar energy is the ultimate renewable energy source because as long as the sun shines, we can draw from it. It’s also a clean energy source because it doesn’t cause pollution.

Solar is so abundant that the amount of sunlight covering the earth in just an hour and a half is enough to power the entire world for a full year (if we were to capture it all)!

What are the sources of renewable solar power?

Concentrating Solar Power (CSP) is used to generate electricity for power plants. These plants are designed to concentrate the sun’s energy to drive traditional steam turbines or engines that create electricity for mass use. The thermal energy concentrated in a CSP plant can be stored and used to produce electricity day or night. Unlike power plants that use natural gas to supply electricity, CSP plants don’t burn fuel.

Solar Photovoltaic or Solar PV is the most common solar technology used for rooftop solar. Photovoltaic refers to the process that converts sunlight into electricity: voltage is created in semiconductors as they are exposed to photons (elementary particles of light). There are two forms of solar PV systems: crystalline silicon panels, which are typically used in home installations, and the less common thin film strips. Solar PV only produces electricity when the sun shines, but home batteries can store extra energy during daylight for use at night or anytime you need it.

How can solar energy be more eco-friendly?

We’ve talked about how solar energy itself is renewable and clean, but let’s take a look at the carbon footprint of materials involved:

  • Photovoltaic Panels use limited resources like copper, nickel, cadmium and silicon. Processes to mine, extract and separate these minerals do contribute to pollution. In areas lacking governance, they can also mean hardship for miners.
  • Disposing of solar panels isn’t easy yet. They have a long lifespan, typically 25-30 years, but do need to be handled correctly once they’ve reached that end. Right now, it can be expensive to recycle them, and more measures are needed to prevent the possible leaching of chemicals.
  • Lithium-ion home batteries (which are often combined with solar panels for backup energy storage) also contribute to the demand for a mineral that is both difficult to mine and recycle.

So does the environmental impact of these materials outweigh the benefits of solar energy? Scientists have answered this question by defining energy payback time (EPBT) — the amount of time it takes for a solar system to generate enough clean energy to “pay back” the energy it took to produce the materials. Most rooftop systems realize their energy payback within 1-4 years. To put that into perspective, think about a system built to last 30 years. After that short EPBT, almost 90% or more of its lifespan is marked by clean energy only!

The future of solar energy is bright

It’s undeniable that we need strong alternatives to fossil fuels if we want to protect our planet. Solar energy offers a solution that’s already far less impactful to the environment and continues to improve. We’re optimistic about the coming advancements in cleaner production processes, governed practices and improved recycling.

The personal benefits of solar energy are also clear: you can reduce your carbon footprint, contribute to a better future for your family, and save money doing it. Want to learn how much you could save? Talk to a Baker Home Energy Solar Professional today.

Ask how we can help you save

What defines renewable energy? You’re not alone if you’re asking this question as you consider going solar. Let’s dig into what it means and why it matters.

Is solar energy renewable?

To answer this question, let’s start with a few definitions.

  • Solar energy — energy from the sun’s rays (solar radiation)
  • Electricity — the flow of electric charge
  • Photovoltaic Effect — the process that converts sunlight into electricity

If you see where this is going you’ve probably also read How Solar Works, which explains how electricity is produced by a solar system. Here we’ll summarize at a high level: solar panels use the photovoltaic effect to transform the sun’s energy into electricity.

Now, let’s look at the two main types of energy sources:

Nonrenewable energy comes from sources that cannot be replaced or can only be replenished through extremely slow natural processes. Think: limited supply. Examples include fossil fuels like coal, gas and oil, as well as nuclear energy.

Renewable energy comes from sources that can be easily and naturally replenished. Essentially, they cannot be depleted. Examples include solar, wind, hydro, biomass and geothermal.

So, we know that solar energy converts sunlight into energy and sunlight is a source we can’t diminish. Based on this, solar energy is a renewable energy source. The U.S. Energy Information Administration even calls solar the ultimate energy source because humans have been using the sun’s rays for thousands of years for warmth and to dry food (like meat, fruit and grains) without reducing any availability. In fact, it’s estimated that the amount of sunlight covering the earth in just an hour and a half is enough to power the entire world for a full year (if we were to capture it all)!

How green is solar power?

When we talk about how green an energy source is, we look at the effects created when we use it. Generally, non-renewable energy sources have to be refined or burned to produce electricity, which creates greenhouse emissions. In 2020, the EPA estimated almost three-fourths of human-caused emissions came from burning fossil fuels alone. Greenhouse gas emissions add huge amounts of carbon dioxide, methane and nitrous oxide to our atmosphere, trapping heat and causing Earth’s temperature to rise. This leads to climate change and the intense heat waves, uncontrollable wildfires and storms we’re experiencing worldwide with alarming frequency.

On the other hand, solar energy gets a green stamp of approval according to the U.S. voluntary market. But what exactly makes solar energy green? Remember the photovoltaic process that converts sunlight to electricity? During that process, no carbon emissions are created, earning solar energy a green power reputation.

Having said that, we should also consider the materials we use to harvest and store solar energy, like solar panels and home batteries. Simply put, there’s a carbon footprint involved in manufacturing and disposing of these products. While still far less impactful than nonrenewable energy, it’s important that the solar industry continues to innovate and improve. Find out more by checking out Why is Solar Energy Renewable?

Big changes are taking place in the electric power sector these days, from the decline in coal power to the rise of renewables and energy storage. In this blog we explore these changes and how they’re affecting utility business models and the future of energy.

10. Coal Power in Decline

Coal power is on the decline because of its environmental and health hazards. Environmental restrictions and public opinion are causing investors to reconsider their support of coal. According to SNL Energy, about 25,000 megawatts of coal power capacity has been retired since 2009. In addition, Bloomberg New Energy Finance predicts that 17% of U.S. coal power generation will disappear over the next few years. A lot of coal power’s disappearance can be accredited to new Environmental Protection Agency rules to reduce pollution. Fewer investors means the price of coal power isn’t where it needs to be to sustain the industry. The U.S. and the world are shifting away from nonrenewable sources, like coal power, towards renewables, like solar and wind, in order to combat climate change because the use of non-renewables causes a significant increase in harmful greenhouse gases. At the 2015 UN Climate Change Conference that took place in Paris, one of the main goals was to reduce carbon emissions worldwide, meaning less coal power and more environmental conciseness as international pressure rises to fight climate change.

9. Natural Gas Is Growing

Natural gas is set to become the U.S.’s primary source of energy before 2025. This is driven by an abundance of domestic shale gas production in recent years. Due to this abundance, U.S. power plants are switching from coal power to natural gas. However, while natural gas use is increasing domestically because of its abundance in U.S. soil, few foreign nations will replace coal plants with natural gas like the U.S. is doing. But it’s important to note that as renewable energy prices continue to drop, dependence on natural gas will eventually fall.

8. Grid Parity of Renewable Energy

Renewable grid parity occurs when an alternative energy source, such as solar power, can generate power at a levelized cost of electricity that’s less than or equal to the price of buying power from the utility grid. Because different utilities have different solar billing mechanisms, and because the price of electricity varies by region, grid parity of renewable energy hasn’t been reached everywhere. However, Southern California has higher than average electric rates. With the cost of renewables continually declining, and utility rates continually rising, renewables in Southern California are quickly reaching grid parity. In fact, rooftop solar is now cheaper than the grid in 42 American cities, which equates to 21 million single-family homeowners that can expect to pay less for solar-generated electricity than for the electricity they would normally buy from their utility. Grid parity has been reached across California, with cities like San Diego and Los Angeles making the list of the top 50 cities where solar has reached parity with the grid.

7. People Are Depending on Utilities Less

Like I mentioned above, electricity rates are rising, while the price of renewable energy is falling. Because of this, people are depending on utilities less. More and more households are choosing to shift away from the coal power and natural gas that are used by their utilities and are choosing instead to reduce their environmental impact and save money with solar power. As of Q3 of 2015, there was enough solar capacity in the U.S. to power 5 million average American homes. Unlike coal power and natural gas, switching to solar allows you to generate your own electricity, meaning you’re less reliant on your local utility and their ever-increasing rates.

6. Utilities Are Going Solar

Many utility business models are working to shift away from coal power and natural gas towards renewables like solar. Greentech Media is forecasting almost 28 gigawatts of added utility solar between 2017 and 2020, which is over 17 gigawatts more than they originally anticipated thanks to the recent extension of the Investment Tax Credit. Solar has been a part of utility business models for more than two decades, and we’re seeing more and more utilities are deploying utility-scale solar projects. In fact, Baker Electric has installed 758 megawatts of utility solar.

According to the Solar Energy Industry Association (SEIA), “a utility-scale solar power plant can be one of several solar technologies – concentrating solar power (CSP), photovoltaics (PV), or concentrating photovoltaics (CPV).” They go on to explain that “what distinguishes utility-scale solar from distributed generation is project size and the fact that the electricity is sold to wholesale utility buyers, not end-use consumers. Utility-scale solar plants provide the benefit of fixed-priced electricity during peak demand periods when electricity from fossil fuels is the most expensive.”

5. Debates Are Heating Up Over Rate Reform

Due to the fact that so many utility customers are turning to rooftop solar to generate their own electricity, utility business models are changing to include higher electric rates. We can see this here in California with the battle between utilities and solar companies over net energy metering, the billing mechanism for solar customers. Also, a new utility rate structure was recently passed by the California Public Utilities Commission (CPUC) that will result in most residential customers seeing their electric bills increase over the coming years.

4. Utilities Are Modernizing the Grid

With all the changes that are coming to the energy sector, utilities are having to modernize the grid to keep up. All of the new utility-scale and distributed renewable capacity coming on the grid means there’s a growing need for utilities to modernize. In 2014, the International Energy Agency estimated that because of the increase in renewables, the U.S. would need to spend $2.1 trillion by 2035 on grid technologies and infrastructure. These advances include new technologies like smart meters, two-way grid communication devices and energy storage.

3. Utilities Are Buying Storage

Battery storage goes along with adding more renewable energy to the grid. An example of this is Southern California Edison, which is choosing energy storage over the natural gas peaker plants they’ve traditionally used to meet sudden shortfalls in electricity. Natural gas fired peaker plants have received community and regulatory resistance in California, so it makes sense that utilities are turning to energy storage to meet sudden peaks in demand.

California regulators have asked the three biggest utilities to line up 1.3 gigawatts of storage capacity by 2020. That’s because energy storage is a much cleaner fall back than traditional natural gas plants. Colin Cushnie, SCE’s vice president of energy procurement and management, said that “batteries can also meet peak demands with lower emissions than natural gas-fired peakers by charging during low-demand periods when excess wind and solar energy is being generated, and discharging during peak demand periods, which displaces the need to burn incremental natural gas in a peaker.”

2. Utilities Realizing it’s All About the Customer

Utilities are realizing that it’s about the customer so they’re doing more to meet individual needs. Because of this, utility business models are shifting towards delivering information on customers’ desired platforms, and towards being more customer-centric. Lynn Good, CEO of Duke Energy, which is changing its business model to meet individual customer needs, said that customers “want flexibility. They want different tariffs. They want their bill options to be different. They want products and services. They might want rooftop solar. They want communication in the form that they want to be communicated with and in a language that they understand.” All of these wants are leading to changes in the way utilities have traditionally done business. More on that here.

1. Utilities Exploring New Business Models

Utility business models are changing due to the rise of renewable energy technologies and their shift towards being more customer-centric. States like California, Hawaii, Massachusetts, Minnesota and New York are doing the most to push their utility business models into the future. Utilities are feeling pressure from the government to increase reliability and to reduce emissions across the country through incentives like the Environmental Protection Agency’s Clean Power Plan. All of the new trends mentioned above are leading to more shifts than ever before in utility business models.

2020 started off with a rate change by the southern California utilities. These rates affected electricity costs for most homeowners in San Diego County, Orange County and Riverside County. The two main utility companies in Southern California are San Diego Gas & Electric (SDG&E) and Southern California Edison (SCE) – and both announced rate changes in early January that were not planned or expected by most in the industry.

Your electricity in 2020 is likely to cost more. Rate changes like this (there were four from SDG&E in 2019) also frustrate homeowners. Solar panels are one excellent way to take control of your energy; with them you become a producer of renewable energy. Another step towards energy independence would be a home battery, which allows you more control over the management and use of the green energy you are producing.

Whether or not you have the advantage of a solar system and a home battery, you still have the challenge of understanding the complex and changing Time-of-Use billing plans. Each household has unique needs, so the ideal solution is to contact an energy expert with the resources to go over your historical usage and also to look ahead to your anticipated energy needs.

Bernadette Del Chiaro, Executive Director of the California Solar & Storage Association (CALSSA) recently wrote an op-ed that appeared in the Sacramento Bee. In the article, Bernadette describes the critical energy challenges that most of us Californians are all too aware of.  She believes that solar coupled with an increased adoption of home battery systems — supported by State incentives — is one solution to our growing energy challenge. Our team at Baker is pleased to share this important information with homeowners throughout Southern California.

Graphic of California state shape as a battery charging icon almost emptyThe cost of the energy solution can be seen in terms of dollars today, or in terms of the costs later that encompass the instability of California’s electricity grid, an increase of fire danger, time lost due to power outages, and the missing out on some potential green energy job growth.

The increased adoption of solar panels for homes, businesses and government buildings has given more Californians access to the clean, renewable energy our state needs. Ms. Del Chiaro tells us it’s time to take the next step. As she puts it in her story, “The need of the hour is to empower consumers and communities to build a safer, more resilient local energy supply. We need to re-imagine a creative, brave future where millions of people can keep the lights on with local clean energy.”

A growing storage solution is home battery backup hardware. Many California homeowners and businesses have already discovered the benefits of an energy storage system, but more work needs to be done at the government level to accelerate the adoption of local storage systems. Ms. Del Chiaro states, “California needs to put forward energy solutions that are as big as the problems that need to be solved. Toward that end, Governor Newsom should announce a plan to build a million solar batteries in five years. This will support the creation of more resilient homes, businesses, and communities throughout California.”

Big costs here might better be considered investments. Not only would solar panels coupled with solar battery storage improve the efficiency and enable growth of current businesses, but down the road energy independence of these entities would allow cost savings as well. “…In an energy landscape bolstered by storage, the state would be empowered by a comprehensive solar and storage policy that pays for itself over time. A clear and sustained initiative would give companies the certainty they need to ramp up manufacturing, streamline installations, and lower costs.”

Graphic of California state shape as a battery charging icon with half of a chargePower outages in California have been present for years, but they are becoming more frequent due to the increased fire danger. Our grid infrastructure is currently in need of repair or replacement. Until the long-distance utility power delivery system problems are resolved, local home battery backup and businesses with a lithium-ion battery system or other battery technology storage systems could be the better way to keep our state moving without interruptions. Ms. Del Chiaro wrote in her op-ed about the current roadblocks to quick, widespread adoption of local energy storage, “The blackouts necessitate local energy supplies and provide conditions for them to thrive, but outdated policies and barriers from utilities impede consumers from getting cost-effective, clean and reliable solar and storage technologies. Solar and storage could be powering communities in need, particularly in times of crisis, and saving energy, money, and lives, but the reliance on a broken, unsustainable electric grid endures. California should be doing more.”

The cost of not incentivizing local energy storage and a move toward energy independence is large. Ms. Del Chiaro points out some startling facts, “We lost roughly 200,000 MWh of power in the 2018 and 2019 blackouts. In human terms, that means schools shut down, food goes to waste, businesses shutter, wells stop pumping, traffic slows, and people in critical need of power for medical assistance are stranded… …The writing of sustained fire danger may be on the wall: PG&E’s blackouts are not the economically or socially sustainable answer. There is a better solution.”

And as we experience strong rainfall in the 2019-2020 rainy season, that means stronger plant growth and therefore more fuel for wildfires during the 2020 fire season. This will further exacerbate a problem that has already been getting worse, “Recent PG&E blackouts are the most significant outages in our state’s history, but California has always had the most unreliable power service in the United States—outpacing runner-up Texas by almost double the number of power-cuts in the last ten years.”

Graphic of California state shape as a battery charging icon fully chargedThe solution lies in a government program to help speed and spread the adoption of these electricity storage solutions. It also requires more companies with the capability to design and install these systems. “We need to prioritize and incentivize solar and storage technology for individuals, low-income housing, businesses, and schools in order to lower costs and remove barriers. We need to support a local, clean energy revolution, where communities lead the way in building local energy that is safe and reliable. The time is now.”

It may seem far out of reach, but as has been proven in California’s recent past, the right program can effect rapid change. Bernadette Del Chiaro suggests we, as a state, approach home battery backup systems in a similar way to the successful incentive programs to grow solar pv panel systems. She suggests this bold idea, “What Governor Schwarzenegger did for solar panels in the wake of the 2001 energy crisis – with the Million Solar Roofs Initiative – Governor Newsom can do for energy storage with the Million Solar Batteries Initiative…. …The cost of going solar dropped 80% during Schwarzenegger’s Million Solar Roofs Initiative. We can do the same for energy storage with the help of big, bold leadership.”

In addition to the cost in terms of budgets, dollars, and time lost, increasing the use of home battery backup systems will increase our use of clean, renewable energy (and thereby lowering California’s carbon footprint) by stretching out the hours of each day we’re able to use that solar energy toward our daily energy usage. “We are seeing more businesses, homes and government agencies turn to solar and storage for a reliable energy alternative. Today’s solar battery is not only affordable, it allows us to make the sunshine at night to power our homes, and in the future our electric cars.” And more renewable energy use helps fight environmental concerns that we are intending to conquer. “Solar installations paired with storage improve air quality and address the very real threat of climate change in actionable, accessible ways…”

Graphic of California state shape as a battery charging icon with power lightning bolt iconA great additional benefit to the implementation of a solar battery storage initiative could be the creating of more green jobs in California. As Ms. Del Chiaro puts it, “…In addition to significantly reducing energy costs for all utility customers, local solar and storage technology is also job-intensive: mobilizing the workforce in safe, skilled, and secure working conditions in the communities we live.”

The benefits are many and are great. Solar energy has led the charge to reliable, renewable energy sources, and home battery backup and storage optimizes the management and use of this solar energy. Ms. Del Chiaro gets the final word with, “Local, smart energy resources like solar roofs and garage batteries can transform our energy system into one that puts consumers first, keeps the lights on for everyone, helps prevent more grid-caused disasters, and is one of the most concrete and tangible ways to engage everyone in fighting climate change.”

There needed to be a solution to utility infrastructure-related fire hazards after the tragic Camp fire in 2018 and the 2017 wine country fires, both of which occurred during the fall. So in 2019, with instances of high winds, Pacific Gas & Electric (PG&E) made the decision to cut power to approximately 800,000 customers in mid-October. These high-risk areas were vulnerable due to high temperatures, low humidity and the high winds that could bring down power lines and ignite dry vegetation.

The move was one of great caution, but brought new risks, plenty of inconvenience, and was certainly not a perfect solution.

The move was one of great caution, but brought new risks, plenty of inconvenience, and was certainly not a perfect solution. The challenge for the utility was to prevent fires yet keep the power on for customers, particularly those in rural settings, and most particularly in areas with dense growth surrounding them. Now in late October 2019, San Diego is seeing Santa Ana wind conditions and the “red flag warnings” of possible power outages.

There’s a lot of frustration from utility customers. Some point fingers at improper planning, failed equipment upkeep or outdated technology. Others voice disapproval at what’s considered by many as a third world solution to California’s energy problem — one of the wealthiest, technology savvy and advanced regions on the planet.

A more common frustration for utility customers is the inconvenience – and in some cases danger – of losing power through planned or unplanned power outages. Although an immediate fix at the power company level is being determined, the average California homeowner can take control of their home’s energy production and storage by installing a home solar system and a home solar battery.

Over 200,000 San Diego County homeowners now enjoy the benefits of a home solar system. Home solar power gives homeowners more control over their electricity by turning them into energy producers. As an additional benefit, solar panels produce clean, green, renewable energy. Through net metering, excess power is sold back to the utility grid to offset power purchased through the grid during nighttime hours. But the dream of many homeowners, especially those who have already faced or anticipate facing increasing power outages in the San Diego area, is to produce and store their own electricity. This solution enables energy control and backup power when the grid goes down. The result is a great, green solution to combat San Diego’s increasingly common power outages.

There are several advantages to pairing a home solar battery with a solar system. The most obvious, and most dramatic, is energy independence through the ability to keep and use your own electricity. Rather than being at the mercy of your electricity utility, you can have your own power on tap. Here are some considerations: If you were to price the perishable food in your refrigerator and freezer right now, what number do you think you’d come up with? You might have hundreds of dollars of food that could go to waste in the event of a prolonged power outage. And power outages are affecting the increasing numbers of home-based workers. When your home power is out, your home office is closed for business. And with the use of computers and tablets for schoolwork, the kids are out of luck too. There’s also your cell phone – most people charge their phone each evening to start the next morning with a full charge in that tiny battery’s storage capacity. In the event of a power outage, home solar batteries with lithium ion technology (not lead acid batteries you find under the hood of your car) can allow you to start the next day with your phone battery fully charged, fresh food and the kid’s homework complete.

There’s also the importance of emergency preparation – this is especially pointed when you consider the cause of the current planned increase of power outages is due to the real threat of fire. Possibly the most critical element to keeping you and your family safe in any emergency, including a brush fire in the area, is communications. Any emergency kit contains the basics – water, food, medical supplies… candles and flashlights… batteries and a radio… but imagine if your ‘emergency’ kit contained electricity. The ability to maintain normal household basics is not only a good defense against the inconvenience of a blackout, but also your reduced ability to react to emergencies. It’s a safety issue, and in an emergency you want to have all possible resources available, including power for your TV, radio, and to keep cell phone batteries charged. And adding batteries to create a larger battery bank increases your home’s battery storage capacity – extra energy to discharge when the utility has failed is a comforting concept.

An incidental benefit of adding home solar battery storage to a home solar system is this: home solar is connected to the grid in order to be able to send electricity back to the utility. But when the grid goes down, those solar panels on your roof are no longer feeding their energy through your inverter and into your home’s solar system. The power grid can’t have electricity traveling through it in case crews are repairing a portion of the grid, so solar panels are not able to deliver any of their electricity to the home. With the addition of a home solar battery, the solar cells gain the ability to function like any other off-grid systems – producing DC energy from the sun with solar panels, converting it to AC power through the solar system inverter, and using it directly without being tied to any other energy sources. So not only does a home solar battery store electricity for use during power outages, but it allows the solar panels to continue producing “current” electricity just as you would during a ‘regular’ day on the grid or a typical day for a home with off-grid solar. Your home would then be functioning normally during the day – all because of the independence a home solar battery gives your home power system – and that same battery capability gives you stored energy to use during the evening and night. A single home solar battery provides power to a few critical circuits, but multiple home batteries can be added to boost home battery capacity to high enough levels to keep the entire home at full capacity. The benefit of flexibility in a home solar battery storage system means it can be built with the addition or more lithium-ion batteries as your needs increase.

Here’s an interesting dilemma: as more homeowners have discovered the benefits of solar energy systems, it has totally changed the electricity needs of the area. For example, during a bright, sunny day (like we have almost year-round in San Diego) many households have zero energy needs from the utility company. The solar panels are producing over 100% of their energy demand, and in fact are sending the excess produced energy back to the utility company to distribute (sell) to homes that do not have residential solar panels. But when the sun sets, the excess electricity going to the utility drops, and the homes that were running on the power of their own solar energy systems then need to buy power from the utility. This causes a rapid increase in demand, and one the utilities cannot meet with their standard powerplants. They need a way to ‘ramp up’ their power production, and the solution in many cases are peaker plants. These are power plants designed to ‘spool up’ quickly to meet spiking demands for electricity on a day to day level. The peaker plants do a good job of producing the power, but it is not clean energy or renewable energy. This is dirty energy, often burning natural gas which is a fossil fuel creating emissions and increasing a city’s carbon footprint. Lessening their personal carbon footprint and that of their region is something that many owners of home solar systems are trying to accomplish. Additionally, one reason energy rates are rising is due to increased demand requiring more peaker plant-produced electricity.

With a home battery, a conscientious homeowner could use battery power during the hours of spiking  energy demands (which generally coincide with ‘on-peak’ hours when electricity is at its most expensive) limiting the need for peaker plant generated energy.  This is an environmentally conscious use of a home energy storage system that simultaneously helps you limit or avoid paying the highest utility rates.

Some homes contain generator systems as solutions for back-up power in the case of a blackout out or planned power outage. This is a more common solution in areas of the world where extended winter-time power outages are very common. Home generators bring in some problems, such as cost and noise, in addition to increasing a home’s carbon footprint (in contrast to solar electricity storage systems that are charging green, renewable energy into lithium-ion batteries). For homes in San Diego, particularly those that already have a home solar system, a home solar battery provides benefits a home generator cannot match – including the ability to use it in a daily manner for extra energy not just as an emergency back-up power plan. This means your emergency power can work for you by lowering energy costs daily since solar battery savings can be seen every day to combat the ever-rising cost of electricity.

In addition to all this, there are financial incentive programs that help reduce the cost of a home solar battery system. One of these, the Federal Investment Tax Credit, applies to solar energy systems, including solar battery storage that is charged by a home solar system. This tax credit, usually referred to as the ITC, is scheduled to end in 2022. At its current 30%, the total cost of a solar system and home solar battery can be applied directly to your tax liability (consult your tax expert if you won’t be able to use the full tax benefit for the tax year in which you purchase your system). In terms of today’s cost savings, if the average cost of a solar electric system is thirty thousand dollars, that would be a cost savings, in the form of a direct tax credit, of nine thousand dollars. Starting in 2020, the ITC is reduced to 26%. After that, in 2021, drops to 22%, and in 2022 the tax credit goes to zero. This is for residential solar and home solar battery systems only. The ITC for commercial systems will remain at 10%. The ITC benefit will reduce the payback period that it takes for a solar system and home solar battery to pay for itself.

There are many benefits to owning a solar power system with home solar battery storage. The major benefit is the ability to keep key circuits in your home powered in the event of a planned or unplanned power outage. Many of these outages can last for days, and the inconvenience and cost of being ‘in the dark’ makes the investment in a home solar battery look even more attractive, and in some cases critical. Solar panels + a home solar battery is the best solution for keeping you and your family safe and functioning during the next power outage.

If you’ve made the decision to go solar, congratulations, there are many benefits to becoming your own energy provider. Installing solar panels on your home is a big step, and getting the right home solar system will affect your system’s power output, how long it will last, how much support you’ll have over the decades of renewable energy it produces, and how satisfied overall you’ll be with the return on your investment.

At Baker Electric Home Energy, we are driven to design and install a top quality system. We are a long-standing, family-owned, local company built on over 80 years of electrical contracting experience. To learn more please to go our home page.

We want you to be informed so you can make the right decision on what San Diego solar installer you chose to design and install your home power generation system. To assist you, we’ve put together this list of solar terms. Use it as a reference when picking the best solar installer for your home, or read through it to get a stronger overview of the solar process so you can ask better questions when shopping for the company that will become your partner in your path to clean energy production, money saving for years, and your resource for all questions related to your home and its energy production, energy efficiency, and energy management.

AC Disconnect

This is an electrical box separate from the Main Service Panel that allows your house power to be shut down.

Applied Credits

This is a term you might see on your SDG&E bill related to credits your solar system has created and sold back to SDG&E for that month or in a previous month. Prior to being applied, these are called Remaining Credits.


This term just refers to the collection of solar panels, as a whole, for either your rooftop solar or ground mount solar system. Your solar array might include all the panels together in one plane if your rooftop design and orientation with the sun allows that as an ideal array design, or your home solar may be comprised of several smaller solar arrays due to factors such as whether you have a good roof for solar or if your house is oriented in a way that doesn’t allow an ideal direction for the solar panels to face throughout the majority of daily sunlight.


This is a mounting system in which panel mounts are connected to a weighted-down base rather than being mounted to a rooftop or a ground mount array frame. This is not a common method of solar panel rooftop mounting but can be the right option for some unique rooftop mounting challenges and might be the best option if your roof can’t take solar panels in a more cost-efficient way.

Baseline Allowance

This is a billing term for San Diego residents participating in Tiered Rate Billing. This amount is determined by factors including the location of your house, the types of appliances you use, and various other factors to determine your amount of ‘cheap electricity’ or your lowest cost electricity you’ll see on your bill before the billing rate increases with the next tier.

Battery AKA Home Battery

See: Home Energy Storage

Battery Capacity

This is the amount of energy storage your single home battery or home energy storage solution (multiple batteries) can store. In most cases, a single home battery stores enough electrical power to operate just a few key circuits in the case of a power outage or to use your stored solar energy at night.

California Climate Credit

This is a credit that California residents see on their electric bill twice a year and on their gas bill once a year. This is part of California’s fight against climate change. It stems from a program that requires electricity and gas providers to reduce greenhouse gasses through carbon credits, and this results in a credit to California rate payers which lowers their bill.

California Solar Consumer Protection Guide

This is a helpful guide created by the CPUC that is designed to make solar customers aware of what goes into the process of selecting the best solar installer for them, rights they have, and what they should expect when planning a home solar system. On September 30, 2019 it became a requirement that any homeowner going solar would need to sign and initial this agreement in various places within the guide. The solar provider is required to submit this signed guide to the IOU (Independently Owned Utility) such as Southern California Gas & Electric or Southern California Edison before the system will be granted a Permission to Operate letter (the CPUC has the right to audit this). This additional step in the process of picking the right solar installer is a very good thing. This guide helps customers evaluate solar installers and well as makes them aware of other possible options and resources. At Baker we are in favor of this new step and encourage all homeowners in San Diego considering solar to read this guide in advance of the required time – that is, we suggest you read it as early as possible in the process of finding a great solar installer in San Diego. If you sign this contract you are not under any obligation to go forward with solar – don’t let any solar installer tell you otherwise. Your signing and initialling of this guide only verifies you have read and understand the contract. Although the guide is 23 pages long, it contains many graphics and is not a dense read – the material is very digestible so please do not be discouraged from looking at this guide as early in the process of picking a solar contractor as possible. Here’s a link to the CPUC Guide. Additionally, reading customer reviews of all the solar companies you’re considering is also a good way to find the best reviewed solar company in your area.


This stands for California Alternative Rates for Energy and is a program that provides discounts (30-35%) on electricity and gas bills for low-income customers who quality and are registered in the program.

Cell AKA Solar Cell AKA Photovoltaic Cell

This is one ‘square’ of one PV solar panel. It is the piece that turns sunlight into electricity through the photovoltaic process. Several cells mounted and linked together make up a solar panel. These solar panels are also called Modules or solar modules.

CESA AKA Clean Energy States Alliance

This is a coalition of clean energy groups coordinating their efforts and helping to boost clean energy development and clean energy use throughout the US.

Community Solar

This is an option to use renewable solar energy to power a home or apartment that you don’t own. This can make sure that from 50% to 100% of the electricity you buy from your provider is solar generated green power. This can make your electrical costs change in either direction: your electrical bill could increase or decrease but Community Solar is a good option for renters who wish to consume clean energy in Southern California. If this sounds like a good option for you to increase your use of green energy, contact your energy provider for options they may offer.

Community Solar Green Tariff Program

This is a program for Disadvantaged Community households to get a lowered electric bill (20% discount) by subscribing to solar farms that are located within 5 miles of their neighborhood.


Your Solar Power Company – the company that you buy your home solar from which may be the same company that installs your rooftop solar panels (or they could subcontract the solar installation to another solar installer specific company). San Diego solar power companies need to have a current Contractors License (see Contractors License). There are many San Diego solar power companies (some are local solar businesses some are local offices of national companies) so in addition to researching solar energy companies for the correct Contractors License, it’s a good idea to look for top solar companies in San Diego that have been in business in the city or local area for a long time and have a brick and mortar facility and great customer service rather than just a few employees with a work truck. The best solar power company for you is one that will still be around years down the road, and one you can get in touch with through a visit or a phone call to a real person (not pre-recorded messages). Your home solar pv system should give you decades of home solar energy production and quickly work off the initial investment in the solar system to provide essentially free electricity for many years beyond the point that your rooftop solar panels pay for themselves. (solar power systems that benefit from the ITC tax incentives will pay for themselves sooner; beware, these incentives are dropping: 30% tax credit in 2019, 26% tax credit in 2020 and 22% tax credit in 2021 for residential solar systems. Commercial systems have a 10% tax incentive that will last beyond this time).

Contractor’s License

Your residential solar installer must have a C-46 (Solar Contractor), C-10 (Electrical Contractor) or B (General Building Contractor) contractor’s license and you have the right to know their license number. Baker holds residential and commercial licenses including a C-46, C-10 as well as C-39 (Roofer) and C-20 (HVAC). Our parent company Baker Electric, Inc. holds a B (General Building Contractor) license. Baker Electric Home Energy’s contractor’s license number is 858088. If you find yourself working with or considering any San Diego solar power companies who do not have the proper contractor’s license you can report this to the Contractors State License Board at 800-321-CSLB.


The California Public Utilities Commission regulates privately owned Utilities, including the electric utilities. The CPUC has been in the news recently (September 2019) for creating and implementing the California Solar Consumer Protection Guide. It’s a great resource to help anyone looking for home solar solutions to learn more about what to expect in terms of solar costs, getting solar quotes, and overall solar energy solutions. It’s also a good resource for finding the best reviewed solar company and top solar experts in your area as well as some ways to best determine which is the best solar power company for you. We’ve written out some of the tips from this guide, and how Baker fits in with those topics. We feel Baker is the best solar company in San Diego and hope this guide helps you come to that same decision. Here’s a link to that blog article, and here’s a link to the complete guide. (which must be read by anyone who wants to get solar on their home, so it would be most advantageous to read it early in your journey so it can help you find the best solar company).

Clean Energy

This refers to energy that does not cause pollution to the atmosphere when used. A home solar system creates clean energy, which is often also called green energy. In addition to major cost savings on electricity, the use of clean energy is a big motivator for many homeowners to learn about home solar.

CSLB AKA Contractors State License Board

This is the organization that licenses and monitors contractors’ licenses. Its website is a resource you can use to look up a potential Solar Installer to confirm they are a licensed contractor. The CSLB website is http://www.cslb.ca.gov/


This stands for Disadvantaged Community and in terms of home solar power discussions describes neighborhoods in areas that suffer from multiple sources of pollution.

DAC-Green Tariff Program

This is a program that allows households to have all of their electricity offset by solar generation and also receive a discount on their energy bill (20%). This program is for households in a Disadvantaged Community. For this the solar panels are not necessarily installed on the home, the solar power can be produced off the property.


This is modeled after California’s SASH program and is focused on families living in disadvantaged communities (specifically they must live in one of the communities that is in the top 25% most disadvantaged communities). Like the SASH program, the DAC-SASH also bring job opportunities in the solar industry.

Electric Grid AKA The Grid

This is the electricity infrastructure and delivery system. People very often use this term as the system they are trying to live independent of by ‘going off the grid’ or ‘living off the grid.’ For a solar powered home to go off the grid, if it was to run at night with solar power, it would need some sort of energy storage system (home battery).

Electricity Provider

Your Utility. For most homeowners in San Diego this will be San Diego Gas & Power (SDG&E). In other areas of Southern California is might be Southern California Edison (SDE).

Energy Efficient Home

This refers to a home’s insulation, its appliance energy draw, and the occupant’s habits in terms of maximizing the energy used. It does not relate to how the electricity is produced or stored. This relates to going solar as one component of energy needs – if a home can be made more efficient, then the ideal size of the solar system, namely the number of solar panels required, might go down and result in a less expensive solar project, saving you money up front with your solar investment as well as creating energy savings into the future. For info on your home’s HVAC system and its energy efficiency options you can learn more at this page.


As it relates to a PPA (Power Purchase Agreement), which is an option to get solar for no money down type arrangements, this is the set amount the monthly payments will increase each year over the course of an agreement. (in a PPA the homeowner (or property owners) does not own the solar system attached to their house).


This stands for Electric Vehicle, which means a pure-electric car, truck or motorcycle, not a hybrid. EVs require a charging station to recharge their battery. Most drivers who have adopted an EV do it for concern for the environment and the desire to consume less fossil fuels and use more clean energy for their transportation. A home with solar and an EV charging station is the next level of clean energy use because a car charged from a home solar system bypasses any dirty energy created from Utility power plants.

EV Charging Station

With reference to home charging, this is a dedicated EV car charging station at your house that can charge your car in the most efficient way. If you charge your car at night, it would wait until your rates drop. If you charge your car during the day at home and you have home solar, it would obviously send the electricity your home produces into your car’s battery before selling it back to the Utility for optimized energy savings.


This stands for the Family Electric Rate Assistance Program. This is similar to the CARE program but for households that don’t quite qualify for that program. It gives an electricity discount of 12% to families who qualify.

Free Solar

The term Free Solar is often used as a sales pitch, possibly sometimes referring to an arrangement like a Solar Lease, in which the electricity is paid for but there is “Free Solar” put on the homeowner’s roof (though homeowners do not own these solar power systems or the solar electric power they produce). Another perspective would consider free solar after the solar power systems have paid for themselves through savings in energy costs. After about five to seven years, on average, properly designed residential solar energy systems will have paid for the initial investing in a solar system, and from that point all the solar electric energy could be considered free electricity. It’s not uncommon for families, once using solar power systems to generate renewable, natural energy, to enjoy their electricity more. This shows in things such as running their air conditioning as they wish once energy costs are not a limiting factor.

Going Green

This is just a slang term for reducing your carbon footprint by using more natural energy and less energy produced by burning fossil fuels (lowering greenhouse gas emissions). There are various levels and approaches to going green. One great benefit of installing a home solar system is that not only is it a very impactful way to use natural energy but green solar also saves money (another good kind of green) on energy costs in the long run. So while some changes people who are concerned about the environment make to their lifestyle can cost a little more, converting your home to solar energy winds up saving thousands of dollars in the process of lowering greenhouse gas emissions. Because of this long term savings realized through green solar technologies, it’s important you get a high quality system installed by one of the top San Diego solar power companies that is designed right for your needs. The best first step is to research the best companies in San Diego that design and install solar energy systems to create your perfect green solar power system and the best energy storage home battery system for your home.

Green Energy

Green energy is natural energy produced in sustainable ways and is clean and friendly for the environment when compared to dirty energy such as that made through the burning of coal and gas (fossil fuels) which increase greenhouse gas emissions. Green energy is also renewable energy. If you want to use more green energy and your home doesn’t currently have solar, your first step is to find the best San Diego county solar power company in your area and get a bid for a home solar electric system. For an investment in solar it’s good to get several bids to find not only the cheapest home solar, but also the best value in residential solar. With the long term benefits involved with green solar technologies, if you don’t have it now you should consider on the near horizon solar power for your lifestyle. Take the first step by researching the best San Diego solar power companies today.


The utilities’ infrastructure of electricity delivery. Homeowners who are not connected to receive power from or sell power to the utility are considered “off the grid.” For homeowners looking for energy independence or just preventing energy bills so they are not victim to rising electricity rates, off-the-grid solar energy solutions, especially as home batteries improve, is becomes less of a fringe concept for property owners. Homeowners interested in going off the grid also may be interested in cutting edge smart home solutions to increase a home’s efficicney as well as improve their lifestye. For more on home energy technology read about it here.

GRID Alternatives

This is a non-profit solar installer that delivers discounted rooftop solar for households that qualify based on income and neighborhood data parameters; GRID Alternatives works through the SASH and DAC-SASH programs. In addition to helping with low cost solar system installation this group provides on the job training through government backed programs.

Ground Mount

This is a method of mounting solar panels into their solar array that is not on a home’s rooftop. The panels are mounted on frame designed at the optimal angle and orientation to the sun. This is an option if your home has enough acreage, or acreage that is not useful to you otherwise. This is a much less common mounting method compared to rooftop solar, and since the mounts are lower they can have more shading issues compared to rooftop solar.

Battery AKA Home Battery

See: Home Energy Storage

Home Energy Storage AKA Energy Storage AKA Home Battery AKA Battery AKA Battery Storage

This term is usually used interchangeably with the incorporation of a home battery. It’s most often paired with a PV solar system so that the rooftop solar charges the home battery as a way to store that electricity rather than send it all back to the utility so the home has back up power in the case of power outages or blackouts. There are homes that install a home battery that is not charged by a PV solar system, though those batteries do not qualify for the ITC Tax Credit. Incorporating a home battery also allows the solar panels to produce independently of the grid, so during a utility grid shut down (from planned power outages or unpredictable blackouts) the solar panels can still produce power for the house to use as well as potentially store back up power in the battery storage for use during hours after the sun has gone down. You can read more about home batteries here.


This is the acronym for the International Brotherhood of Electrical Workers. The local San Diego chapter is Local 569. Not all solar systems installations are done by union contractors (or even full time employees since some companies in San Diego subcontract solar installation work to various solar installers), so it is a good idea to research the qualifications of the installation crew when considering San Diego solar power companies. [Note: Baker uses IBEW Local 569 electricians for all solar systems installation work within Local 569’s territory (San Diego city and area). These are full time employees and solar experts and we are proud to have the best trained and most knowledgeable solar electric employees in the city].


This is the group that performs the rooftop solar installation; significant here is that this group can be a part of your Solar Provider, or a group that is sub-contracted by your Solar Provider. To get the best San Diego solar panels installed, ask any solar contractor if they use regular, full-time employees for doing the solar panel installation.

Inverter AKA String-Inverter AKA Solar Inverter

This is a component of any solar pv system that provides electricity to a home. The power generated from the solar panels is produced as DC (direct current). The Inverter or Inverters turn DC electricity in AC (alternating current) electricity. A solar inverter (or inverters) is part of all solar energy solutions that create power for your home using current solar technology. The top solar experts will know the best brand and type of inverters to use with your rooftop solar panels.

IREC AKA Interstate Renewable Energy Council

This is a group that works state by state to make sure households get the best solar power options for all income levels of owner and renters.

ITC AKA Investment Tax Credit AKA Solar Tax Credit

This stands for Investment Tax Credit. It’s been a long standing tax credit to encourage homeowners to adopt solar through its incentive programs. This tax credit was initiated years ago when solar adoption was not as popular as it is today, and solar panels were not as efficient as they are today. This government incentive, a federal tax credit that shortens the payback period before a residential solar system pays off the initial system purchase cost, is going away. 2019 will be the final year the ITC will provide consumers with a 30% tax credit, but you need to have a new system that is installed and up and running with an official Permission to Operate letter before the end of 2019. At the start of 2020, the Investment Tax Credit drops to 26%; again your system would have to be installed and officially operating before the end of 2020 to get the full 26% tax credit. At the start of 2021, the ITC drops to 22%; again, for systems that up fully and officially operational before the end of that year. After the end of 2021, the ITC for residential systems goes away. If you get your system installed in time for the tax credit, we advise you to talk to your tax consultant about the tax credit rollover rules if you don’t think you’ll be able to take full advantage of the tax credit for the year of your system installation. [As an aside, the ITC does continue on beyond 2021 for commercial solar systems, but that tax credit is at 10% and does not apply to the home solar systems incentive programs.] You can read more about the ITC tax credit here.

Kilowatt Hours aka kWh

Like it sounds, this is a measurement of power that is the amount of 1000 watts for one hour. As it relates to building a residential solar system, the typical output for a San Diego home solar system would usually fall into the range of 7.5 to 8 kWh. Remember a family’s energy use, both current usage based on a history of the home electrical bill, as well as projected energy use based on things like the addition of a pool, and Electric Vehicle charging station, an air conditioning system, or just the tendency of new home solar system users as they tend to enjoy their appliances with more freedom resulting in higher energy use.

Main Breaker AKA Main Disconnect

Like the name implies, this is the overall power breaker switch / disconnect found inside your house’s Main Service Panel (AKA Breaker Box).

Main Service Panel AKA Breaker Box AKA MSP AKA Load Center

This is your house’s ‘power box’ where you have access to the breaker switches for your Main Breaker as well as the breakers for the various power circuits in your house. Your home will have this regardless of whether or not you have solar power to your home. In some cases, the Main Service Panel will need an upgrade with the addition of solar to your home.


These are the companies that make the individual items, such as the solar panel, the inverter, or the home battery. Solar Providers might be exclusive to manufacturers for certain components or might provide options for each component when designing solar energy systems – such as the option between solar panel manufacturers based on different benefits. The Manufacturers have nothing to do with the assembling or mounting of their components in the solar pv system on your house. This is important because the Manufacturers provide the equipment warranty and usually their own customer service – so you want components with a good manufacturers warranty, real-person customer service, and a Solar Provider that will work with you through their own excellent customer service in the case of hardware warranty issues.

Micro-Inverter AKA Microinverter

Like the name suggests, this is a small Inverter. In most San Diego home solar systems an array of solar panels feed Direct Current to one inverter (sometimes there is more than one inverter to handle the electricity coming from various arrays of solar panels). In this standard arrangement, abut 20 to 30 solar panels could feed their electricity into one Inverter. This is a good cost-conscious way to design a home solar system but it susceptible to poor electrical output of an entire Array if as few as one solar panel falls under some shade or has a failure. With a solar system built using a Micro-inverter attached to each solar panel, each solar panel can remain productive independent of any other issues within the bank of solar panels. This can add to the per solar panel cost of solar pv systems but the increase in solar capacity of overall output of the San Diego solar panels (and therefor the cost per watt of electricity for that day) may help offset the cost of the Micro-inverters. So Micro-Inverters don’t help the solar panel efficiency as much as help the solar array efficiency, because efficient solar panels won’t be effective if they are limited by a shaded solar panel that drops the power efficiency of the array. (also see Optimizer which performs a similar function).

Minimum Charge Adjustment

This is a billing term that San Diego residents will see on their electricity bill from their utility companies. The current minimum charge as of the writing of this list from SDG&E is $.33 per day, except for customers who are participants in CARE, FERA, or Medical – that minimum charge is $.164 per day.

Module AKA Solar Panel

‘Module’ is another term for Solar Panel. It is not a layman’s term and likely is something you would only hear when discussing solar system design or solar installation with a solar professional, or something you might overhear if listening to solar companies speaking with solar panel manufacturers.


This stands for North American Board of Certified Energy Practitioners. This group certifies Installers. [Note: Baker has NABCEP certified personnel and been invited to present at a number of their training conferences].

Net Metering AKA Net Energy Metering AKA NEM

This is the agreement solar customers have with their utility where a home with a solar system sells back excess energy to the utility for close to retail rate (there are a few fees that cannot be backed out, so the electricity sell back is not a precise one-to-one sell back ratio). This excess energy can be carried forward until the True-Up or Settlement Bill, which usually occurs every 12 months. At this point, excess energy beyond what the home used drops from the utility’s retail rate to the utility’s wholesale electricity rate. This is a much lower electricity rate and this big drop in the price of electricity being sold back to the utility is one of the reasons an oversized home solar system (with too many solar panels and an excess of energy production beyond the household energy needs) is avoided during the design and installation of a solar system.

NEM Charges AKA Net Metering Charges AKA Net Energy Metering Charges

For homeowners with SDG&E as their power company, this is the amount of kWh charged, not including any NEM Credits, under their net metering billing.

NEM Credits AKA Net Metering Credits AKA Net Energy Metering Credits

These are the credits your San Diego home solar system generates and that have been applied to your utility account / utility bill.

Net Energy Metering Non-Bypassable Charges

These are charges that cannot be overcome with excess electricity production from your solar array. These are charges such as: Nuclear Decommissioning, Public Purpose Programs, DWR Charges and Competition Transition Charges.


For the purpose of discussing solar, Offset is the overproduction of electricity that is designed into your system so that it can sell electricity to your utility during the day to offset the electricity you will later purchase (through use) during the non-producing hours of your system. Fortunately, sunny San Diego Solar Power is an abundant and reliable source of renewable energy.


An Optimizer is one of the solar energy products that solar contractors can incorporate into a system that allows some similar functionality of a Microinverter solar panel arrangement but at a lower cost compared to a Microinverter set up. A solar Optimizer is connected to each solar panel and allows independent energy production from each solar panel, so their solar production is not limited by the lowest-producing solar panel in the solar array. There is also the added function of being able to monitor the electrical output of each solar panel (this is possible with a Microinverter system also, but in a standard Inverter system (String-Inverter) system you can only monitor the solar array’s total power output, not individual solar pv panels). Any top solar panel company in the industry will be able to determine if your photovoltaic solar panels would increase their power output with the incorporation of an Optimizer.


This stands for Property Assessed Clean Energy. This is similar to a Solar Loan but with lower up front costs but more restrictions in the future including, for example, possibly a first-priority lien on your home. Usually the electric bill payment is done at the same time property taxes are paid, or other times through the house’s mortgage payment.

Panel AKA Solar Panel

This is the sheet of Solar Cells that make up one module. For the purposes of home solar in San Diego, this refers to the PV panels that are approximately five and a half feet long, three and a quarter feet wide, and about an inch thick. The production output of solar energy of Panels had a rapid increase about a decade ago. Solar Panel development and improvement continues, but their increases in efficiency and production are not growing rapidly from year to year because the current state of rooftop panels is at a good point of efficiency and power output.

Peaker Plant

This is a large powerplant that provides electricity to a city but that is only ‘turned on’ during times of rapidly increasing power demands (though that can mean every day during on-peak energy time such as when people are getting home from work). The advantage of Peaker Plants is that they can ‘accelerate’ rapidly in their ability to create energy, the disadvantage is they are not producing clean energy and they are not producing cheap energy – the average cost of the electricity is higher for the utility companies and those costs manage to show up in your utility bills. Peaker Plants are built to fill ‘holes’ in spiking energy demands that the traditional power plants cannot meet.

PPA AKA Power Purchase Agreement

A Power Purchase Agreement is a way for a homeowner to consume renewable energy without putting in the upfront costs to purchase a pv solar system. In a PPA, the homeowner agrees to buy all the power a system produces, usually at a rate below that of the Utility. The solar power is generated through a solar system on the house that is owned by the Solar Provider. The price paid for electricity in this arrangement increases (usually annually). This is a low cost way to use green energy without spending a lot of money up front, though there are considerations in the long run and in the event of a home sale before the PPA has expired, such as whether or not the PPA allows the agreement to be transferred to the new home owner or if the agreement must be bought out by the home seller. To read about PPA vs a lease, you can read more here.

Production Guarantee

This can be a Solar Provider’s guarantee/warranty that a designed system will deliver a set amount of electricity over specific time periods. This performance warranty can be backed up with a financial make-up payment if the system falls short of this amount of electricity, or in some cases a performance warranty shortcoming can be ‘fixed’ by the addition of more solar panels to the system, at the discretion of the solar companies. This Production Guarantee/performance warranty is different from a solar panel warranty from the solar panel manufacturers – this Production Guarantee is a guarantee on the design and size of the solar power system as conceived by the solar panel company. A performance warranty on the system is another reason to find a top solar power company that uses quality solar manufacturers when planning the solar capacity of your home system. This energy output of the system’s pv cells is related to energy bill savings but is not a guarantee of a lower electrical bill or decreasing your energy costs – since customer usage is a big factor in determining that.


This is your San Diego Solar Power Company AKA the Solar Contractors you hire. They may or may not be the same in-house company that installs your solar panels and home solar system.


This is an abbreviation for photovoltaic, which is the term for the type of solar photovoltaic panel used for the standard home solar system. This differentiates today’s modern solar panels which generate electricity from other forms of using solar radiation. A simple example of a solar system that is not a solar photovoltaic system is the pool heating system that uses conduction to heat pool water “directly” by pumping it through a large-area system (often mounted on a roof) to expose more of the pool water to the sun’s heat. In nearly all circumstances when people discuss residential and commercial solar systems today they are referring to solar photovoltaic systems. Here’s an interesting blog about different types of solar systems.


The energy of the sun, as light. This is the energy the photovoltaic cells in your solar panels use to convert sunlight into electricity. When you own a solar system you become an electricity producer are your own energy provider.


This is an electronic device that is in effect the opposite of an Inverter. This device converts alternating current into direct current. When PV solar panels convert sunlight into energy, they produce direct current and nearly every home solar system converts that electricity into alternating current.

Reduce Your Use Day Reward

This is a term SDG&E uses for San Diego homeowners on a billing plan that provides rewards based on energy use timing under certain billing plans – another reason why isn’t not simple to determine the best SDG&E billing plan for you.

Remaining Credits

These are credits you might see on your SDG&E bill that represent excess Kilowatt Hours that your solar system has produced but have not yet been applied to your outstanding charges. Once they are applied they are called, not surprisingly, Applied Credits.

Renewable Energy

This is green energy aka clean energy that is produced in a way that doesn’t deplete natural resources of the earth and that can ideally operate with zero greenhouse emissions. In terms of becoming your own electricity producer, solar and wind are the two home renewable energy sources people mention. Other sources of renewable energy are rain, tides, waves, and geothermal heat. Most, other than solar power and wind power, are not common self-produced energy sources in San Diego. Today solar companies build solar cell panel based systems. There are solar companies that can use solar tiles, though these are not as efficient or cost effective today as a panel based solar array.

Renewable Energy Certificate AKA RECs

These are certificates that you would be eligible to receive if you own a home solar system. This allows you to make the claim that you are producing clean energy and avoiding the byproduct of greenhouse gasses in the production of that energy. These certificates are for making environmental claims; unless you have a known need for you to receive RECs there is a high likeliehood that they would be of no benefit to you.

Roof Mounts

Solar panels are attached to your roof with roof mounts designed to work specifically with the type of room on your house. Whether you have a composite single roof, tile roof, concrete roof, or even a flat roof, there is a dedicated and best solar panel roof mount system for your house.

Rooftop Solar

This is the most common home solar system that installation companies build which includes solar panels mounted on your roof. Another, though less common, solar panel mounting option is a ground mount, which mounts solar panels on their own frame that is build separate from the house.


The Single-family Affordable Solar Home program is a California effort to not only bring more solar homes into neighborhoods that traditionally have been left out of the option to create their own renewable energy, but it also provides education on the benefits of solar and help families enroll in programs to save on solar in California. The program also supports job training in solar industry jobs. This program enables more families to go green with solar energy.

SCE AKA Southern California Edison

A major local utility that provides electricity to Southern California homes. For most homes in the San Diego region, the utility would be SDG&E. The territory of SCE generally covers areas north of the SDG&E territory.

SDG&E AKA San Diego Gas and Electric

A major local utility that provides electricity to San Diego and the San Diego region – This is likely your San Diego electric company.

SEIA AKA Solar Energy Industries Association

This is a solar trade association for the U.S. solar industry that also provides a guide for purchasing a solar system for homeowners in the market for San Diego solar panels and a home system.

Settlement Bill

See: True-Up

SGIP AKA Self-Generation Incentive Program

This is a program to help lower the cost of home energy storage with rebates through a government rebate program. These are good rebates for different emerging distributed energy resources (including home battery energy storage) but the incentives program has been set up in a way that makes it challenging for even the best San Diego solar power companies to ensure the customer will receive any rebates when purchasing home energy storage systems before the funding of these incentives has been depleted. If you have solar electric companies in San Diego guaranteeing you will receive SGIP incentives rebates with the purchase of an energy storage solution, you should be careful to check that those solar companies have assurances in place to make sure you receive the funds from these rebates.

Solar Breaker

This is the breaker inside the Main Service Panel for the Solar System. This is different from a separate AC Disconnect.

Solar Energy System Disclosure Document

This is a one page document, created by the CSLB (Contractors State License Board) as a form to be filled in by your solar contractor, that discloses all the costs of your home solar system. At Baker, our long standing and continuing policy is to provide this to our customers. We include it as the first page of any solar contract.

Solar Financing

See: Solar Lender

Solar Guide AKA Solar Consumer Guide

A term often used to refer to the California Solar Consumer Protection Guide. This is a document that informs customers considering home solar with valuable information. If you move forward with solar and decide to install a PV solar system on your home in California, as of September 30, 2019 you will be required to read and sign this guide. This guide is not a commitment to buy, this guide is informative but must be signed or initialed in various places before the utility will turn on your system. This is a resource designed by the California Public Utilities Commission (CPUC) to help you. It’s also a good idea to check solar reviews on sites like Yelp and Angie’s List, and look at the BBB rating of any solar companies you’re considering; and each company’s website can often give you an idea of how professional they are. But the CPUC’s Solar Guide will give you a great understanding of what to look for and what to expect once you’ve narrowed down the list of solar companies you’re considering, because the best reviewed solar company might not be the best company in your area or the best company for you.

Solar Installer

This is the group that performs the actual installation; sometimes this is a department of the Solar Provider’s company.

Solar Lease

This is a way for homeowners to rent/lease solar power systems that are installed on the roof of their homes. The homeowners get the electricity that the solar energy systems produce and sign an agreement to pay monthly to the Solar Provider (this monthly payment usually increases a set percentage each year per the agreement). The Solar Provider owns and maintains the solar energy systems. These agreements are usually 20+ years in length. If the homeowner wishes to sell their house during this agreement period, there may or may not be an option to transfer the Lease to the new home buyer. There may or may not be a requirement to buy out the lease, which may or may not have a penalty attached to it.

Solar Lender AKA Solar Loan Company

A financing company that specializes in loans and financing options for home solar systems. Other financing options besides a Solar Lender include banks or credit unions which might provide a better loan with a lower interest rate. It’s good to investigate all the options and rank the various lending options and loan offers before making the final decision on financing new solar energy systems. Solar companies will have Solar Lenders they work with but you can pick your own, too.

Solar Provider

This refers to the San Diego county solar company that you buy the solar system from. They can be the same solar electric company that does the solar power systems installations as well.

Solar Water Heater

These are not photovoltaic solar systems, these are a more simplistic, ez solar system that could be built without electrical expertise and that don’t produce electricity, they just heat your home’s water either directly or indirectly. With San Diego’s great weather, water freezing within the system is not a major factor in the decision of the best Solar Water Heater system for you. These solar systems do not produce renewable electricity, but they do help you go green by requiring less electricity to heat your home’s water through the natural energy of the heat of the sun.


This is a set of one or more solar Arrays in solar power systems. Most home solar systems will have a string of arrays. The top San Diego solar power companies will be happy to show you exactly how those solar pv panel arrays will be built onto your home’s roof.

Three Day Cancellation Period AKA Right to Rescind

You have at least three business days to cancel a solar contract if you change your mind. At Baker, we won’t require a customer to move forward if they’ve changed their mind, so we’ll work with you beyond the three day requirement if you decide not to continue forward. If you find yourself with a solar provider who will not honor this 3 Day Cancellation Period requirement, you can contact the Contractors State Licensing Board at 800-321-CSLB.

Tiered Rate Billing

This is one way your power company might charge you for using electricity. In this electricity billing plan, your electricity cost increases when you reach levels, or tiers, of use for each billing period. The initial rate is relatively cheap electricity, but most homeowners will use more electricity than this tier allows before electric rates increase within that billing period. From there, overuse will kick the cost of energy into becoming even more expensive electricity. In Tiered Rate Billing, the electricity costs rise in stages based on total electricity use for that billing period and is independent of when during the day or week that electricity is consumed by the house. In San Diego with SDG&E, Tiered Rate Billing is not an option when adding solar to a house today. In the past, customers were allowed to stay on this rate plan even with the adoption of solar power systems and those customers are allowed to say on their previous Tiered Rate Plans for a set period of time.

TOU Billing AKA Time-Of-Use Billing

This is the current billing plan for San Diego county solar homes with solar power systems. This cost plan for energy bills varies the cost of electricity in San Diego by having different electric rates for different periods of the day. The purpose of this billing plan is to incentivize San Diego homeowners to use less electricity during On-Peak hours (generally between 4:00PM and 9:00PM, though it varies by plan and by day of week and different halves of the year) to avoid or lessen the electrical demand spike during this time when people are getting home and turning on the lights and appliances, cooking dinner, running the dishwasher, etc. There are many plans within TOU billing at SDG&E, and the best solar power companies in San Diego can help you find the plan that’s right for you to lower your energy bills. [At Baker we have a proprietary app that helps us find the billing rate plan with your solar system and energy use that will allow you to have the most efficient billing costs to work for your needs and provide you with the lowest energy bills] For more information check out this blog post.

True Up AKA True-Up Bill AKA Settlement Bill

This is the annual bill from your electricity utility that balances home energy use with your home energy production to determine what your overall bill will be. At this point Solar Credits are not carried forward any longer, so excess credits are converted to the electricity wholesale rate, which is a much, much cheaper price for electricity. Unfortunately, in this case of excess production of solar energy (often a result when residential solar power systems are built too large), that cheap electricity rate works against you since you’re selling it back to the Utility at that wholesale rate. This is one reason why the best solar power companies in San Diego will design home solar systems that cover as close to exactly how much energy families will use today and into the future for the best return on investment when trying to reduce energy bills. Solar power systems size is part science and part art since there are many factors to consider for both energy use today and energy use, and the price of electricity from the utility companies in San Diego, on future energy bills.


This is the power company (San Diego Gas & Electric in most cases for residential San Diego homes) that provides electricity to your house. In many areas there is only a single choice for an electricity provider but with community power providers there could be more options on where customers buy their home electricity.

Utility Wholesale Rate

For the purpose of the solar energy producing homeowner, this is significant because it is that rate you would be selling back you excess energy for if you’ve carried excess electricity up to your True-Up or Settlement Bill. Excess electricity sold back to utility companies prior to this True-Up or Settlement bill is sold back (through net metering) at a rate nearly equal to the value of that electricity when it was produced. In short, you get the ‘market value’ of any electricity your solar produces (less some fees that are built in that net metering cannot bypass) during a ‘regular’ month, but once your energy consumption vs. Your energy use is tabulated over a 12-month period, the excess solar electric energy that your system produced is bought by the Utility at this much lower Utility Wholesale Rate.

Whole House Fan

This is a house venting system designed to circulate air; it is a strong fan not an air conditioning system. It can be useful to push hot air out of a home prior to turning on the home air conditioning system. This is not a solar product, but some solar companies also have HVAC divisions and therefore can handle this install for you as a part of making your home more energy efficient.

Workmanship Warranty

This is any warranty offered by the Solar Provider/Solar Installer that covers their work separate from the hardware warranties of the Manufacturers of the components. [Baker provides solar and solar and battery customers with a 10 year Workmanship Warranty as well as excellent customer service.]
