San Francisco is paying its way to become a more energy efficient place by helping its citizens afford solar panels. The city’s board of supervisors recently approved the Solar Energy Incentive Program, GoSolarSF, which is now the country’s largest municipal solar program. With an annual budget of $3 million for the next 10 years, the program offers up to $6,000 to residents and up to $10,000 for businesses in the form of tax incentives for private solar installations. It will give out even more than that to low-income San Franciscans and nonprofit, multi-family residences. The program’s goal is to eventually have 10,000 solar rooftops in the city compared to the 770 they have right now. The program started accepting applications on July 1, 2008. Once they begin building, other cities will hopefully start to spend a little also.
