The spread of residential solar power has been largely a middle-class affair.
Despite plunging prices in the last seven years, rooftop solar arrays remain an expensive home improvement, costing $15,000 or more. A 2013 study by the liberal research and advocacy group Center for American Progress found that 67 percent of solar arrays installed in California went to ZIP codes with a median household income between $40,000 and $90,000. Wealthier areas accounted for almost all of the rest.
A new California program, however, aims to make solar power available to lower-income families — using money from the state’s fight against global warming.
