Finding a Solar Hot Water Licensed Contractor

The CSI-Thermal Program maintains a list of eligible contractors that meet licensing and other requirements for participating in the program. Eligible contractors are also required to take a one-day training class that explains CSI-Thermal Program rules, standards and protocols.

Self-installers are also required to take the one-day training course in order to receive a CSI-Thermal Incentive payment. Classes are held on a regular basis. Contractors and self-installers wishing to take the class should contact the Program Administrator in their area for a schedule of classes and information on how to enroll.
