Missouri Solar Energy Industries Association

The Missouri Solar Energy Industries Association (MOSEIA) is the nonprofit association leading Missouri’s solar industry. Our mission is to expand solar markets and to generate jobs and prosperity for Missourians across the state.

Support Solar

Solar customers deserve to be compensated for the real value of the energy they provide. That’s why, this winter, when net metering was under attack in the state legislature,  Missouri Solar Energy Industries Association (MOSEIA), showed up to lead the fight. 

Even with less than 24 hours’ notice, in a snowstorm, during a pandemic, MOSEIA members made the trip to Jefferson City to testify against bills seeking to charge unfair fees to solar customers.
