Colorado’s Solar Energy Industries Association

Established in 1989, Colorado Solar Energy Industries Association (COSEIA) is the award-winning nonprofit association leading Colorado’s solar industry. Our mission is to expand solar markets and to generate jobs and prosperity for the people of Colorado. Together with hundreds of solar business members we work to advance solar policy, remove market barriers, highlight emerging trends, and promote solar outreach and education.

Colorado has a 30% Renewable Energy Standard that has sparked the development of our solar industry. Thanks to COSEIA’s development of the Solar Friendly Communities program and passage of the Fair Permit Act (HB11-1199), Colorado has made solar permitting faster, easier and more affordable.  There are tremendous opportunities in Colorado’s solar marketplace – and as a national leader Colorado often influences what happens in other states. But success in solar doesn’t happen by itself. There are tremendous obstacles threatening our progress and we need your help. Your support is urgently needed and greatly appreciated.

Representing a Wide Range of Solar-Related Businesses

COSEIA represents and leads a wide range of solar-related businesses including manufacturers, distributors, dealers, installers, integrators, financiers, developers, utilities, entrepreneurs, educators and others. COSEIA is governed by an eleven-member Board of Directors that oversees the organization’s strategic priorities, budget and bylaws.
