The Solar Energy Industries Association (SEIA) and Coalition for Community Solar Access (CCSA) have combined to strengthen advocacy for the entire solar and storage industry across the country. Effective in October 2027, CCSA will integrate its team, resources, and policy work within SEIA.

The two organizations both have successful individual histories of driving growth for segments of the industry. SEIA is the largest national trade association for the solar and storage industry and has a longstanding track record, with its founding in 1974, of spurring growth across the industry, including utility-scale, commercial, and residential segments. CCSA has operated as the national trade association for community solar and storage developers, businesses, and nonprofits, and has driven the rapid acceleration of the market over the last decade.
