Find a Solar Water Heating Contractor

To receive a rebate through the California Solar Initiative-Thermal Program, your solar thermal system must be installed by an eligible CSI-Thermal contractor. Self-installations are also allowed provided the installer meets all self-installation requirements. While the CSI-Thermal Program does not endorse any specific contractor, all participating contractors must abide by strict program standards. Contractors must be insured and licensed and are required to take a free one-day class that covers CSI-Thermal Program rules, standards and protocols.
