SRP uses the ratings provided by the SRCC, which is an independent, third-party company who evaluates each system based on the region where they will be located. The OG-300 rating evaluates the entire system from panels to tank. If a solar water heater is OG-300 rated, it means the entire system has been certified to meet applicable requirements.
