Solar power in Iowa is limited, with only 27 MW installed by 2015, ranking the state 29th among U.S. states.[1] Iowa's position as a major wind power provider may have limited early solar investment. Solar on rooftops can provide 20% of all electricity used in Iowa.[2] On June 7, 2012, Sky Factory in Fairfield became the first company in the state to generate all of their electricity from solar power, with the installation of a 54 kW 3500 sq. ft. solar array.[3][4][5] Prior to that one of the largest arrays was the 15.75 kW array on the Marshalltown Public Library.[6] An 800 kW array near Kalona was the largest in the state when it went online in July, 2014.[7]Net metering is available continuously to all consumers generating up to 500 kW, one of the best policies in the country[8] but is given a B because of not being available to large, megawatt users.[9] A feed-in tariff is available for customers of the Farmers Electrical Cooperative for up to 25% of their electricity. It pays 20 cents/kWh for electricity generated, none of which can be directly used – a separate meter is required, in a parallel connection, making it a power purchase agreement, instead of a feed-in tariff.[10] The state of Iowa has proposed a feed-in tariff, in Senate bill SF 225. A separate rate applies for systems less than 20 kW and systems from 20 kW to less than 20 MW.[11][12]

In December 2011, Des Moines-based MidAmerican Energy Holdings, a Berkshire Hathaway company, purchased the Topaz Solar Farm, which when completed, at 550 MW, was the largest in the world.[13][14]
