Green Homes and Smart Homes – moving faster than the speed of light…
The Best Solar Energy Companies – by Zachary Shahan, Solar Energy Contributing Editor
- We’ve known light could be turned into electricity since 1839 when French physicist, A. E. Becquerel, discovered the photovoltaic effect. It wasn’t until the 1950s, however, that the first solar cells were available commercially, when Bell Labs produced them for use in outer space.
- In the decades since, improvements in solar technology have been tremendous, as have drops in solar power cost. Since 1977, the price of solar panels has dropped approximately 100 times over, and solar power is now cheaper than power from the grid for billions of people. Many consumers are turning to solar energy to save money with this renewable energy source.
