The Solar Energy Industries Association (SEIA®) is the driving force behind solar energy and is building a strong solar industry to power America through advocacy and education. As the national trade association in the U.S., we represent all organizations that promote, manufacture, install and support the development of solar energy.
SEIA works with its 1,000 member companies to champion the use of clean, affordable solar in America by expanding markets, removing market barriers, strengthening the industry and educating the public on the benefits of solar energy.
Our member companies consist of installers, project developers, manufacturers, contractors, financiers and non-profits, all of whom see the benefit in joining SEIA and working collectively toward a clean future. Together, we hope to continue the already impressive growth of solar across the United States.
