Solar power in Wisconsin on rooftops is estimated to be able to provide 22% of the electricity used in Wisconsin.〔(Report Argues for a Decentralized System of Renewable Power Generation )〕 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.〔(Net Metering )〕 Best practices recommend no limits, either individually or aggregate, and perpetual roll over of kilowatt credits.〔(Net Metering Model Rules )〕 A 2012 estimate indicates that a typical 5 kW solar array installed in Wisconsin will pay for itself in 15 years and go on to provide an additional profit of $20,238 during its 25-year life.〔(Wisconsin Solar Power Rebates, Tax Credits, and Incentives )〕 Wisconsin's renewable portfolio standard requires 10% renewable sources for electricity by 2015.〔(Renewable Portfolio Standard )〕 ==Implications== In 2007, Wisconsin's largest solar array was the 44.4 kW array on the Urban Ecology Center in Milwaukee.〔(Largest Wisconsin Solar Array to be Dedicated February 10 )〕 In 2011, the largest array was the 360 kW parking lot array in Verona,〔(Epic fires up solar array )〕 which is being expanded to 2.2 MW. A 3.177 MW array is planned for a distribution center in Oconomowoc. The KI convention center located in Green Bay, WI currently has the largest solar PV installation in Northeastern Wisconsin. The new 115-kilowatt array comprises 480 PV solar panels.〔http://search.proquest.com.ezproxy.uwgb.edu:2048/docview/1269689657?OpenUrlRefId=info:xri/sid:primo〕 As of May 2014 there are about 2,250 homes powered by solar energy in Wisconsin. Wisconsin ranks 24th in the nation for the number of solar jobs. Since 2012, Wisconsin has added 800 jobs in the solar industry.〔https://biometeorology.org/milwaukeeidea/hbi/Archive/News/2014-May-In-Focus.pdf〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Solar power in Wisconsin」の詳細全文を読む スポンサード リンク
