Who We Are

The Solar Rating & Certification Corporation (ICC-SRCC) is an ISO/IEC 17065-accredited third-party certification body with programs for the certification and performance rating of solar heating and cooling products. ICC-SRCC’s OG-100 and OG-300 certifications and ratings are accepted throughout North America. ICC-SRCC’s well-known Standard 100 and 300 are specified by dozens of incentive programs, regulations and laws at the local, state and federal levels, and building codes. ICC-SRCC also provides listing programs that assist code enforcement professionals to determine whether solar heating and cooling products comply with codes and applicable standards.

A New Organization, A Long History

The modern solar industry was founded in 1974, following the original oil embargo of the previous year. In the years that followed, energy in all its forms became a national priority. Commercial and residential solar systems were available on a limited regional basis, but public acceptance and adoption was slow at first. As interest in solar grewo, it soon became evident that there was a need for a single, national program that would allow manufacturers to test and rate the performance of their equipment. Such a program would also benefit consumers by providing minimum safety and durability standards, along with thermal performance ratings. To accomplish this, industry associations and a national consortium of U.S. state energy offices and regulatory bodies collaborated to found the Solar Rating & Certification Corporation (SRCC) as a non-profit in 1980. In November, 2014, SRCC became part of the International Code Council (ICC) Family of Companies. ICC develops the family of 15 I-Codes used by all 50 states in the U.S. as the basis of their building codes. ICC-SRCC is now a program of the ICC Evaluation Service (ICC-ES).
