The first version of SRCC Standard 100 was developed in 1981 by the Solar Rating and Certification Corporation (SRCC) as a result of efforts by a consortium including the U.S. Department of Energy, National Renewable Energy Laboratory (NREL), Interstate Renewable Energy Council (IREC), Florida Solar Energy Center (FSEC) and the Solar Energy Industry Association (SEIA). Since that time, the standard has been updated periodically by means of SRCC’s standard development process. The consensus process used by SRCC was consistent with ANSI requirements for the development of voluntary consensus standards including balance of stakeholders, transparency and due process.

    In 2013, SRCC and ICC agreed to collaborate to develop an updated version of the SRCC 100—2013 Minimum Standards for Solar Thermal Collectors and SRCC 600-2013 Minimum Standard for Solar Thermal Concentrating Collectors standards through ICC’s ANSI-approved Standard Development process to seek designation as an American National Standard (ANS). With direction from ICC’s Board of Directors and the SRCC Board of Directors, the ICC Standards Council appointed a consensus committee to develop a single updated standard to establish minimum requirements for safety, performance and testing of solar thermal collectors.
