DECISION MODIFYING DECISION 10-01-022 REGARDING CERTIFICATION STANDARDS FOR SOLAR WATER HEATING SYSTEMS

Summary

This decision modifies Decision 10-01-022, which established the California Solar Initiative (CSI) Thermal Program, regarding certification standards for solar water heating systems that apply for CSI Thermal incentives. This decision grants in part a petition filed by EchoFirst, Inc., and finds that the International Association of Plumbing and Mechanical Officials (IAPMO) is qualified to certify solar water heating systems to Solar Rating and Certification Corporation (SRCC) standards. The CSI Thermal Program Administrators are directed to accept SRCC certifications rendered by IAPMO. Additionally, this decision establishes a process for the CSI Thermal Program Administrators to consider requests for acceptance of SRCC certification performed by entities that are American National Standards Institute accredited listing agencies.
