MOSEIA's mission is to strengthen and expand the solar industry and establish a sustainable energy future for all Missourians.

MOSEIA goal is to accelerate the solar industry in Missouri while raising industry standards. MOSEIA members are required to sign a Code of Ethics vowing to conduct their business with the utmost integrity.

The Industry Association formed in large part to the passage of Proposition C, the Missouri Clean Energy Initiative. Missourians overwhelming supported renewable energy legislation, (66% of the vote) in November 2008, setting Missouri on the path to a cleaner more reliable energy future. Proposition C mandates 15% of the electricity produced by Missouri investor owned utilities (IOUs) comes from renewable sources by 2021, 2% of which must come from solar photovoltaics.

Since the passage of Prop C stakeholders have been working to craft the regulatory language and pass subsequent legislation that would uphold the voter's intent for Prop C. MOSEIA continues to advocate for creating a homegrown solar market that is good for the solar industry as well as the citizens of Missouri.  More Missouri generated solar means energy diversification and more jobs in Missouri.
