The Solar Rating and Certification Corporation (SRCC) is a nonprofit organization that publishes solar heating certification information online (solar-rating.org). Independent test laboratories, accredited by the SRCC, conduct a specified series of tests on collectors and systems and pass the information to the SRCC. SRCC certification is a requirement for the 30% residential solar tax credit and is required by many state, local, and utility incentive programs.
While the SRCC website has all the certification information, navigating it to find what you want can be intimidating. On the SRCC home page, pick Ratings from the left menu bar if you’re looking for collector or system’s certification status or estimated performance data. All of the other menu selections give information on certification rules, policies, and standards, and general information for manufacturers and interested users.
