Solar power has a flexible range of power generation from watts to Gigawatts in size.
As prices continue to fall, solar energy is increasingly becoming an economical energy choice for American homeowners and businesses.
Today, demand for solar worldwide is at an all-time high. The amount of solar power installed in the U.S. has increased more than 23 times over the past eight years -- from 1.2 gigawatts (GW) in 2008 to an estimated 28 GW’s in 2015.
The space industry was an early adopter of solar technology. In the 1950s, the space industry began to use solar technology to provide power aboard spacecraft.
Solar energy is the most abundant energy resource on earth — 173,000 terawatts of solar energy strikes the Earth continuously. That's more than 10,000 times the world's total energy use.
