What California Solar & Storage Association does

California Solar & Storage Association (CALSSA) is a private 501(c)(6) nonprofit trade association founded in 1977 (per firmographic data) or 1979 (per company history) and headquartered at 1107 9th St. Ste. 820, Sacramento. It represents 600+ member companies across California's solar and storage value chain, including manufacturers, designers, installers, financiers, and service providers, as well as residential consumers seeking rooftop solar and storage. CALSSA's core activities are policy advocacy before the California Public Utilities Commission, the state Legislature, and investor-owned utilities; industry networking through seven regional chapters, webinars, and signature events; consumer protection resources including a public contractor finder; and political engagement via its SUNPAC political action committee.

The association's product surface consists of a tiered membership program (standard membership and President's Circle premium tier with approximately 20 named members including Tesla, Enphase, Sunrun, SolarEdge, and GoodLeap), an annual billing cadence, a permitting assistance hotline, supplier and service directories, a solar job board, fact sheets and reports, and member-only webinar programming. Events include the Annual Dinner, Solar Battle of the Bands (co-hosted with Intersolar & Energy Storage North America), an online auction, and regional chapter programming across the Bay Area, Los Angeles, San Diego, Sacramento, North Bay, Central Valley, and Bakersfield. Recent advocacy outcomes include a 13-0 legislative audit committee vote on CPUC interconnection oversight, a $10M complaint filed against PG&E and SCE, and a successful preliminary injunction against the CSLB battery installation restriction rule.

Revenue is generated exclusively through membership dues, event sponsorships, and fundraising activities; pricing is not publicly disclosed. The organization employs 1-10 staff and is led by Executive Director Brad Heavner (since March 15, 2025) following Bernadette Del Chiaro's 12-year tenure.

Direct peers

• Solar Energy Industries Association (SEIA): SEIA is the national trade association for the U.S. solar industry, providing policy advocacy, research, and member services. It is the most direct national-level peer to CALSSA, with the same membership-dues model and focus on federal/state solar policy advocacy. SEIA's California state engagement makes it an overlapping peer to CALSSA in California's regulatory arena.
• Vote Solar: Vote Solar is a national nonprofit advocacy organization focused on pro-solar state-level policy. It directly competes with CALSSA in California legislative and regulatory advocacy on net metering, interconnection, and consumer protection, and shares overlapping funder/donor networks with CALSSA.
• Interstate Renewable Energy Council (IREC): IREC is a national nonprofit focused on clean energy regulatory reform, interconnection, workforce credentials, and consumer protection — many of the same issues CALSSA addresses in California. It serves as a peer in policy research and best-practices sharing for state-level clean energy associations.
• California Energy Storage Alliance (CESA): CESA is a California-based trade association focused specifically on energy storage policy advocacy. It is the closest direct peer to CALSSA's storage work, serving overlapping storage developers, financiers, and technology providers on CPUC and legislative matters, and competing for the same California storage-policy thought leadership.
• American Clean Power Association (ACP): ACP is a national trade association representing wind, solar, storage, and transmission companies. It is a broad-incumbent peer that overlaps with CALSSA on storage and solar policy advocacy, particularly in California where ACP runs significant state-level engagement.
• Coalition for Community Solar Access (CCSA): CCSA is a national trade association advancing community solar policy at the state level. It is a peer in business-model-specific solar advocacy, often working alongside CALSSA on California community solar and VNEM/NEMA policy questions.

Emerging players

• SunSpec Alliance: SunSpec is a trade alliance developing open standards for distributed energy and solar interoperability. It is an emerging-player peer with partial overlap on solar industry standards-setting and California member companies, but its focus is on technical/data standards rather than legislative advocacy.

Others

• Environmental Working Group (EWG): EWG is a national environmental advocacy organization that recently expanded into California, hiring CALSSA's former Executive Director Bernadette Del Chiaro. It is a coalition partner and former-employer relationship rather than a direct competitor, but it operates in adjacent California clean-energy/consumer advocacy spaces.
• National Association of State Energy Officials (NASEO): NASEO is a membership association of state energy officials that influences federal-state energy policy coordination. It is thematically related to CALSSA's state-level policy advocacy work but is a government-affiliated association, not a competitor.

Broad incumbents

• Smart Electric Power Alliance (SEPA): SEPA is a membership organization focused on the integration of clean, distributed energy resources with the grid, serving utilities and solution providers. It overlaps with CALSSA on storage/virtual power plant topics but is broader, utility-centric, and not California-specific.
