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

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. Therefore there was broad recognition that mechanisms were needed to encourage consumers to purchase these new solar technologies with confidence. States with potentially large solar markets, such as California and Florida, were the first to establish such mechanisms by establishing state testing and rating programs for solar thermal collectors. However, since there was little consistency between each state's approach to testing and rating solar equipment, such programs soon became an impediment to manufacturers who marketed in more than one state.

Test and PoolIt 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 a uniform approach comparing the performance of solar thermal equipment. To accomplish this, the U.S. trade association for the solar energy industry and a national consortium of U.S. state energy offices and regulatory bodies collaborated to found the Solar Rating & Certification Corporation (SRCC).

In 1980, SRCC was incorporated as a non-profit organization whose primary purpose was the development and implementation of national rating standards and certification programs for solar thermal energy equipment. In November, 2014, SRCC became part of the International Code Council (ICC) Family of Companies that is dedicated to the construction of safe, sustainable, affordable and resilient structures. 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 a program of the ICC Evaluation Service (ICC-ES).
