From the San Francisco Chronicle 

San Francisco supervisors gave final approval Tuesday to a program that will create a $3 million fund to provide rebates for residents and businesses that install solar power systems.

The supervisors also gave initial approval to another solar rebate program, sponsored by Supervisor Ross Mirkarimi, to create a $1.5 million fund for nonprofit organizations and low-income residents at or below the city's median income level. That money would fund a one-year pilot program.

Under the $3 million program, sponsored by Supervisor Bevan Dufty, residents could receive between $3,000 and $6,000 for photovoltaic systems that produce at least 1 kilowatt of electricity. Businesses could receive $1,500 per kilowatt installed, with a cap of $10,000.
