SEIA and CCSA have announced a plan to combine their teams, resources, and policy efforts under the SEIA name
The combined group will represent solar and storage across all major market segments, according to the duo
The combined association is expected to begin operating as a single entity from early October 2026
The Solar Energy Industries Association (SEIA) and Coalition for Community Solar Access (CCSA), the two solar and storage industry associations in the US, have decided to merge into a single entity, following approval from their respective Boards of Directors.
While SEIA represents the solar and storage industry across the utility, commercial, and residential segments, CCSA is the national trade association for community solar and storage developers, businesses, and nonprofits. The latter will now merge into SEIA by integrating its team, resources, and policy work.
“By bringing CCSA into SEIA, we’re creating a stronger, more unified voice for the solar and storage industry. Together, we’ll build on CCSA’s success and become a more powerful advocate for every segment of the industry,” said SEIA CEO Tim Pawlenty, who replaced Abigail Ross Hopper in mid-June 2026 (see SEIA Appoints Tim Pawlenty As New President & CEO).
After the merger closes in early October 2026, the combined entity will become the ‘only’ national trade association representing every segment of the solar and storage industry, they claim.
CCSA’s Departing CEO Jeff Cramer believes the combined platform under the SEIA name will bring the scale, resources, and expertise that distributed community power needs to ensure greater access, affordability, and grid reliability for all Americans.
The merged organization will form a ‘single, powerful voice for solar and storage’, representing companies across utility-scale, residential, commercial, and community segments.
The US solar market expanded by 45% year-on-year (YoY) in Q2 2026, adding 11.4 GW DC capacity, while battery storage additions totaled 20.2 GWh during the quarter (see US Added Record 20.2 GWh Battery Storage Capacity In Q2 2026).
Together, solar and storage accounted for 70% of all new capacity added to the grid in H1 2026 (see US Solar Installations Rebound 45% YoY To 11.4 GW DC In Q2 2026).
