Important Update Regarding 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.

The waitlist is shared with new CSI PV applications and can be accessed by selecting Non-Residential Waitlist or Residential Waitlist. 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

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

Today, more businesses are making green part of their routine. From CFL bulbs and recycling bins to dual-pane windows and motion-activated sensors, businesses are doing their part to conserve energy and reduce their carbon footprint. If you own a business that uses a lot of hot water, you may need to step up your green routine by using renewable energy to power your commercial or multi-family property.
