The solar PV system, which will be built atop the Chet Holifield Federal Building in Laguna Niguel, California, is expected to produce more than 1.4 million kilowatt-hours of electricity annually – enough to power roughly 130 homes – upon completion.

The solar project will be powered by 3,808 silicon PV modules from Solarworld and feature inverters come from Advanced Energy of Camarillo, California and PV Powered of Oregon, while the roof mounting system will be manufactured by Sunlink of California.

GSA will fund the project that is anticipated to save about 1.8 million pounds of CO2 gas yearly with assistance from the American Recovery and Reinvestment Act (ARRA) and use the project as a case study and reference point for possible future solar projects.

GSA Region 9 project manager of energy and sustainability branch Kristine Walker said that by increasing the US government’s use of solar power, the nation reduces its dependence on fossil fuels and help create green energy jobs now and for the future.
