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.[1][improper synthesis?]
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,[2] giving the state a B rating.[3]
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.[4][5]
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.[6]
