Legislation that would require large housing developments to include photovoltaic systems on new homes passed the California Senate Housing Committee and is expected to come up for a vote on the Senate floor in a few days. Senator Kevin Murray (D-Los Angeles), author of SB 1652, expects the bill to pass. ?I feel very good about it,? he said. The measure would mandate that new single-family home developments of 25 units or more include 2 kW photovoltaic systems on a certain portion of the homes. The original bill called for 25 percent of new homes to have PV rooftops in 2006 and a 10 percent increase each year until 65 percent was reached by 2010. The goal, however, is in flux. Murray is in negotiations with the governor?s office and the bill?s opponent, the California Building Industry Association. The home-building group does not want mandatory standards, saying that they would increase the cost of a new home by $20,000. Asked where the negotiations were headed, Murray said, ?I expect goals to start low and escalate over time. I also expect some geographic differentiation, making exceptions for foggier areas where it has less value. It doesn?t make sense to have the same requirement in San Francisco and in Palm Springs.? Solar power advocate Bernadette Del Chiaro of Environment California said state subsidies bring the current cost for a 2 kW system down to about $14,000, and that bulk purchasing should get them closer to $11,000. At that rate, she said, the increased monthly mortgage payments would be covered by electricity savings. With 135,000 homes built every year in the state, the bulk of them would fall within this law. Del Chiaro estimates this bill would provide 50 to 60 MW of solar power, tripling the current number of residential PV installations each year. A spokesperson for Governor Arnold Schwarzenegger said the state chief ?does not take positions on pending legislation.? Murray, however, said he expects support for some version of the bill. In his state of the state speech in January, the governor said he wanted half of the new homes in California to be equipped with PV.
