California Solar Initiative Thermal
UPDATE: At this time, there are more than enough applications on the Waitlist to fully subscribe the available remaining incentive dollars. Therefore, we will place the Waitlist on pause as of Friday, April 4, 2014 and will not accept any new Residential CSI applications.
Through the California Solar Initiative Thermal Program, you can receive rebates by installing a qualifying solar water heating system at your home.
Going solar can be rewarding. Installing an eligible solar water heating system at home can help you save on your electric bill and reduce your carbon footprint. First, install a qualifying system; then, take advantage of California Solar Initiative Thermal rebates and bask in the savings.
Learn more about the California Solar Initiative Thermal Program or find a contractor.
How Incentives Work
Rebates are based on how much energy your solar water heating system is expected to displace annually. Eligible single-family residential electric or propane customers can receive rebates of up to $1,834.

Solar energy rises with the sun. As solar production increases, you would purchase less energy from us.
With solar production at its peak, you create more energy than needed, earning you credits for the surplus.
Solar energy goes down with the sun, and you would begin to purchase energy from us.
With solar energy stopped, you would tap into the credit earned during the day to power your property.
