A Dept. of Energy Lawrence Berkeley National Laboratory report released in December shows that, after remaining virtually unchanged from 2008 to 2009, the price of installed solar photovoltaic (PV) power systems in the U.S. declined sharply in 2010.
“PV has priced itself into the market and is now competitive with other renewables,” says Art Larson, a spokesman for San Diego Gas and Electric. The utility signed its first three PV projects in 2010. A total of 305 MW of PV will come under contract in California’s Imperial Valley once construction is complete in 2014.
