Solar Energy Industries Association to Combine with Coalition for Community Solar Access, Strengthening Advocacy for Entire Solar & Storage Industry Across the Country

The Solar Energy Industries Association (SEIA) and Coalition for Community Solar Access (CCSA) announced plans to consolidate, with the integration set to take effect in early October. Both organizations’ Boards of Directors approved the merger, which will bring CCSA’s team, operations, and policy initiatives under the SEIA umbrella.

SEIA, established in 1974, operates as the largest national trade association representing the solar and storage sector across multiple market segments including utility-scale, commercial, and residential installations. CCSA has focused specifically on the community solar and storage segment, serving developers, businesses, and nonprofit organizations. The consolidation aims to create a single national trade association with comprehensive representation across all solar and storage market segments.

According to SEIA CEO Tim Pawlenty, the merger will strengthen advocacy efforts by unifying the industry’s voice on market and policy matters at state and federal levels. The combined organization will leverage expanded resources and network capabilities to represent companies operating across utility-scale, residential, commercial, and community solar segments. Jeff Cramer, departing CEO of CCSA, characterized the merger as an evolution of the organization’s mission to expand solar access while building greater scale and expertise.

The solar and storage sectors continue to demonstrate significant growth within the U.S. energy infrastructure. As of the article’s publication date, solar and storage installations represent over 70% of new grid capacity additions during the year, while the energy storage market experienced record growth in the second quarter. The U.S. continues to achieve manufacturing milestones in both sectors, reinforcing the industry’s expansion trajectory.
