SEIA and Community Solar Coalition Merge to Form a Unified Solar and Storage Voice

Two major American solar advocacy groups are joining forces. The Solar Energy Industries Association (SEIA) and the Coalition for Community Solar Access (CCSA) have announced they will combine into a single organization after both boards of directors gave their approval.

The merger is set to take effect in early October, when CCSA’s staff, resources, and policy portfolio will be folded into SEIA. By bringing community solar expertise under the same roof as the broader solar and storage industry’s main trade body, the two groups aim to present a more coordinated front in Washington and in statehouses across the country.

Community solar has become a fast-growing segment of the U.S. clean energy market, allowing households and businesses that cannot install rooftop panels to subscribe to shared projects. Combining that advocacy with SEIA’s existing reach is intended to give the sector a stronger, more unified voice as policy debates over energy incentives continue.

For the wider solar and storage industry, the move signals consolidation on the advocacy side at a time when federal and state-level decisions carry significant weight for project pipelines and investment.
