How does solar water heating work?
Solar water heating (SWH) systems use the energy of the sun to heat water. This is different from photovoltaic or electric solar systems that use the energy of the sun to create electricity. A solar water heating system includes a storage tank and solar collector(s). Solar collectors are typically placed on your roof top so that the sun can heat the water before sending it to your water heater or a storage tank. Most solar water heaters require a well-insulated storage tank. Solar storage tanks have an additional outlet and inlet connected to and from the collector. In two-tank systems, the solar water heater preheats water before it enters the conventional water heater. In one-tank systems, the back-up heater is combined with the solar storage in one tank. Watch the solar water heating for homeowners video to learn more.
Solar Water Heating Rebates
The Center of Sustainable Energy administers the City of Palo Alto's solar water heating program (SWHP). Rebates are available for residential, commercial, and industrial customers of CPAU. To be eligible, applicants must purchase a new qualifying SWH system and be able to provide a copy of a CPAU bill. Solar pool heating systems are not eligible for this program.

For residential systems, the maximum rebate is $2,719 for natural gas displacing systems and $1,834 for electric or propane displacing systems.

Find a solar water heating contractor
Customers may choose from a list of eligible contractors, who have been pre-qualified to participate in the program, or install the systems themselves. Participating SWH contractors and self-installers must attend a one day training offered by either CPAU or PG&E to qualify. Ready to get started?Look for tips on finding a contractor.
