California’s Tax Board headquarters boasts largest state-owned solar roof

August 11, 2010

The California Department of General Services has installed the largest state-owned solar electric rooftop in California at the Franchise Tax Board’s headquarters in Sacramento.

The 470 kilowatt solar system – generating enough electricity during the day to power the equivalent of more than 400 homes - will supply the building with nearly half of its energy needs, reducing expensive electricity purchases from the grid during peak demand periods. The system, which covers 50,000 sq. ft. of roof area, was designed, manufactured and installed by PowerLight Corp., Berkeley. (DGS statement, Aug. 27, 2002)
