Solar power in Missouri has been a growing industry since the early 2010s. Solar power is capable of generating 42.7% of the electricity used in Missouri from rooftop solar panels totaling 28,300 MW.

Net metering is available only during a billing period. Excess generation is credited at avoided cost rate, and lost if any remains after a year, giving the state a B rating.

IKEA installed a 1.28-MW solar array on its St. Louis store which was the largest rooftop installation in the state. It was completed in July 2015.

Missouri's largest solar farm is located in Christian County, just outside of Nixa on a plot owned by Gardener Capital. The farm generates 9% of the power needs of Nixa, Missouri transmission grid.

I am claiming the 26% Federal Tax Credit (ends 2022) i

When you install a solar system, 26% of your project expenses apply toward a credit to offset any taxes you owe that year. This federal tax credit is a major incentive to go solar, but it is going to be phased out by 2024.

To be eligible to claim this credit, you must owe federal taxes.
