Is Solar Energy a Relatively New Technology?


Many people today are under the impression that San Diego solar is a relatively new technology. The sun’s rays have only been harnessed for the past few decades, right? Actually, the history of solar energy dates back 6,000 years. Ancient people may not have turned to a San Diego solar company to install photovoltaic systems on their roofs, but they knew quite a lot about taking advantage of the sun’s energy. Here’s a brief look at solar energy’s history, long before there was solar in San Diego.

  • Stone Age Chinese: The earliest sign of people using solar energy was 6,000 years ago in ancient China. People built their homes carefully to maximize the sun’s heat and light in winter.
  • Greece: About 2,500 years ago, most Greek homes were heated by the sun.
  • Rome: Architects in Rome published books to help the average Roman save on fuel, since firewood was scarce at the time.
  • Galileo Galilei: Much later, during the Renaissance period, Galileo and those he worked with made plans to construct solar-focusing mirrors. The purpose was to focus the sun’s rays effectively enough that they could burn enemy ships as they approached.
  • Leonardo da Vinci: A more peaceful use of the sun’s energy was Leonardo’s plan to build mile-long mirrors to heat water for the wool industry.
  • Industrial Revolution: Years later, engineers in the Industrial Revolution invented solar-powered steam engines with the idea of saving Europe from collapse if they ran out of coal and other fossil fuels.
  • Swiss polymath: The first example of global warming was modeled in 1767 by a Swiss polymath who trapped solar heat in a glass box to demonstrate how carbon dioxide traps heat from the sun.
  • New York City: As electricity began to power cities, the very first photovoltaic array was installed in New York City – in 1884!
  • Enterprising businessmen: In the 1890s, solar made its first appearance in California. Businessmen used the glass box idea to harvest solar energy to heat water.

The notion that San Diego solar isn’t well established is obviously quite false. Of course, technology has grown by leaps and bounds, so it’s no wonder that homes and businesses today are acknowledging its validity and have started tapping into this renewable energy source!
