Electricity produced by solar photovoltaic (PV) systems surpassed solar thermal electricity in installed capacity in 2008. The cumulative installed capacity reached about 440 megawatts (MW) at the end of 2008, eclipsing the 354 MW of solar thermal. Assuming each system installed kW produced 1,500 kWh, the California PV systems produced 661,500,000 kWh (661.5 GWh) of electricity. That's nearly as much as the 675 GWh of electricity by solar thermal in 2007.

Statistics On Renewable Energy & Electricity In California

National Renewable Energy Statistics

The main place for energy statistical data is the U.S. Department of Energy's Energy Information Administration (EIA). Their website is: www.eia.doe.gov

The Interstate Renewable Energy Council tracks nationwide statistics of installed solar.

Highlights include:
  • California installed 58% of all grid-tied PV capacity in the U.S. in 2007 -- and was the number one state in the country.
  • Ninety percent of grid-connected installations in 2007 were in just five states: California, New Jersey, Nevada, Colorado, and New York.
  • California has 69% of all of the grid-tied PV capacity in the U.S. cumulative to date through 2007. California had installed about 33,000 out of the nation's 48,000 solar systems by the end of 2007. The next largest state is New Jersey, with 9% of total installed capacity.
  • California is #1 in Cumulative Installed Capacity per person in the U.S. with 9.1 watts per person.
