What if the collector I want to use in my system is not certified to Standard 100 by ICC-SRCC? Can I still get a ICC-SRCC OG-300 certification for the system?

A current ICC-SRCC OG-100 certification issued by ICC-SRCC is required for all collectors used in most systems submitted for OG-300 certification. In some cases there are exceptions for PV Water Heaters and some types of thermosiphons where the complete system has been tested.
