The California Solar Initiative – CSI

The Go Solar California campaign is a joint effort of the California Energy Commission and the California Public Utilities Commission. The goal is to encourage Californians to install 3,000 megawatts of solar energy systems on homes and businesses by the end of 2016, making renewable energy an everyday reality. The program also has a goal to install 585 million therms of gas-displacing solar hot water systems by the end of 2017.

The California Solar Initiative (CSI) makes powering your home with clean, renewable solar energy easier than ever before by providing a financial incentive for installing qualifying photovoltaic systems on a home or business.

California Solar Initiative rebates vary according to utility territory, system size, customer class, and performance and installation factors. The rebates automatically decline in “steps” based on the volume of solar megawatts (MWs) with confirmed project reservations within each utility service territory.

CSI Incentive Types

Expected Performance-Based Buydown (EPBB) (Paid in dollars/Watt)

  • Ideal for residential and small business projects
