The Solar Incentive Program (SIP) is the most established rooftop solar program in the City of Los Angeles. It originated at the Los Angeles Department of Water and Power in 2000 with a $150 million investment to incentivize the proliferation of rooftop solar in Los Angeles.
With the passage of Senate Bill 1 (2007), the SIP was revised to comply with state law. The updated, 10-year, $313 million program, subsidizes photovoltaic solar panel installation for residential, commercial, non-profit, and governmental customers.
This research identifies the geographic reach the program over the past 15 years through analysis of data that is available on DWP’s website and US Census data.
