We Are California Solar

Since the 1970s, CALSEIA has advanced the common interests of the California solar industry, helping make California's solar market the most robust in the United States. Comprised of California solar contractors, manufacturers, distributors, developers, utilities, engineers, consultants and educational organizations, CALSEIA represents a diverse membership committed to growing the California solar industry. CALSEIA provides solar industry members located throughout California with a presence at the Capitol in Sacramento, at the CPUC in San Francisco, and at hearings and workshops throughout the state. As a policy-dependent industry, it is imperative that the California solar industry engages politically to fight for, and defend, good solar policy in California.
