Solar power in Wisconsin In 2026, Wisconsin rooftops can accommodate approximately 37 GWs of solar capacity and produce 44,183 GWh of electricity, nearly 70% of the statewide generation in 2019. Net metering is available for systems up to at least 20 kW, and excess generation is credited at retail rate to customers next bill. Some utilities allow net metering up to 100 kW. For Xcel customers, kilowatt credits are rolled over monthly and are reconciled annually at avoided cost.[1] Best practices recommend no limits, either individually or aggregate, and perpetual roll over of kilowatt credits.[2]
A 2016 estimate indicates that a typical 5 kW solar array installed in Wisconsin will pay for itself in 13 years and go on to provide an additional profit of $18,860 during its 25-year life.[3] Wisconsin's renewable portfolio standard requires 10% renewable sources for electricity by 2015.[4]
