The Colorado Solar and Energy Storage Industry Leader

Established in 1989, the Colorado Solar and Storage Association [formerly the Colorado Solar Energy Industries Association (COSEIA)] is the award-winning nonprofit that’s leading Colorado’s solar and energy storage industries. If solar and/or energy storage is your business (or in your future) then becoming a COSSA member is one of the smartest moves you can make. Your membership strengthens efforts to expand markets, advance policy, remove barriers, and boosts visibility for your business as a solar and energy storage leader.

Our annual investment levels are based on in-state annual company revenues. We rely on the honor system and expect that all our members are reporting actual revenues.
