Established in 1997 by solar energy advocates, it is an historic and highly-effective membership organization that consists of solar developers, contractors, manufacturers, architects, engineers, consultants and other industry professionals.

In addition to policy advocacy on the state and federal level, MSEIA works with local governments to encourage and aid in the development and rapid adoption of solar installations. The result is a new renewable energy economy which fosters green jobs and decreases the use of fossil fuels.
