Solar Water Heating

Important Update Regarding Residential Incentives for Electric/Propane Solar Water Heating*:

The CSI-Thermal Program (solar water heating) is still accepting new Residential applications for electric and propane solar water heating projects. However, PG&E is currently out of funding for incentives, therefore new applications are being placed on a waitlist.* PG&E has made a request to the CPUC to continue funding the program and you will be notified when a determination is made. Please note, being on the list does not guarantee an incentive. Incentives for natural gas solar water heating systems are still available and have plenty of funding. To monitor available natural gas incentives, please visit

Please check with your contractor for more information. If you are a solar water heating contractor, please visit our What’s New page for more information.

*Only applicable to residential customers of single-family homes who heat their water with electric or propane.
