Solar power in Wisconsin on rooftops is estimated to be able to provide 40.1% of the electricity used in Wisconsin, using 23,600 MW of solar panels.{{cite web|url=http://www.nrel.gov/docs/fy16osti/65298.pdf|title=Rooftop Solar Photovoltaic Technical Potential in the United States: A Detailed Assessment|website=nrel.gov|access-date=21 April 2018}} 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.{{cite web|url=http://www.dsireusa.org/incentives/incentive.cfm?Incentive_Code=WI03R&re=1&ee=0|title=Net Metering|website=dsireusa.org|access-date=21 April 2018|url-status=dead|archive-url=https://web.archive.org/web/20120418132942/http://www.dsireusa.org/incentives/incentive.cfm?Incentive_Code=WI03R&re=1&ee=0|archive-date=18 April 2012}} Best practices recommend no limits, either individually or aggregate, and perpetual rollover of kilowatt credits.{{cite web|url=http://www.irecusa.org/wp-content/uploads/2009/11/IREC_NM_Model_October_2009-1-51.pdf|title=Net Metering Model Rules|website=irecusa.org|access-date=21 April 2018}}

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.{{cite web|url=http://solarpowerrocks.com/wisconsin/|title=2018 Guide to Wisconsin Home Solar Incentives, Rebates, and Tax Credits|website=solarpowerrocks.com|access-date=21 April 2018}} Wisconsin's renewable portfolio standard requires 10% renewable sources for electricity by 2015.{{cite web|url=http://programs.dsireusa.org/system/program/detail/190|title=DSIRE|website=programs.dsireusa.org|access-date=21 April 2018}}

Implications

In 2007, Wisconsin's largest solar array was the 44.4 kW array on the Urban Ecology Center in Milwaukee.{{cite web|url=http://madisonpeakoil-blog.blogspot.com/2007/02/largest-wisconsin-solar-array-to-be.html|title=Largest Wisconsin Solar Array to be Dedicated February 10|website=madisonpeakoil-blog.blogspot.com|access-date=21 April 2018}}{{self-published inline|date=February 2021}}

In 2011, the largest array was the 360 kW parking lot array in Verona owned by Epic,{{cite web|url=https://www.unifiednewsgroup.com/verona_press/news/epics-half-built-solar-field-is-biggest-in-the-state/article_9afd2f94-55f3-5b5a-a637-7f00c7d97347.html|first=Jim|last=Ferolie|date=18 December 2011|title=Epic's half-built solar field is biggest in the state|newspaper=The Verona Press (Unified Newspaper Group)|access-date=2 April 2021|archive-url=https://web.archive.org/web/20210402171231/https://www.unifiednewsgroup.com/verona_press/news/epics-half-built-solar-field-is-biggest-in-the-state/article_9afd2f94-55f3-5b5a-a637-7f00c7d97347.html|archive-date=2 April 2021}} which is being expanded to 2.2 MW. A 3.177 MW array is planned for a distribution center in Oconomowoc.{{citation needed|date=July 2016}}

In June 2016, the 2.3 MW Rock River solar project near Beloit became the largest solar farm in the state.{{cite press release |title=Wisconsin's largest solar project delivering power to Alliant Energy customers |publisher=Alliant Energy |date=18 July 2016 |url=https://www.prnewswire.com/news-releases/wisconsins-largest-solar-project-delivering-power-to-alliant-energy-customers-300299985.html }}

The KI convention center located in Green Bay currently (as of 2013) has the largest solar PV installation in Northeastern Wisconsin. The new 115-kilowatt array comprises 480 PV solar panels.{{cite press release |id={{ProQuest|1269689657}} |title=KI Installs Largest Solar Energy Array In Northeast Wisconsin |publisher=KI |date=16 January 2013 |url=https://www.prnewswire.com/news-releases/ki-installs-largest-solar-energy-array-in-northeast-wisconsin-187145441.html }}

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. Between 2012 and 2014, the state added 800 jobs in the solar industry.{{cite web |url=https://biometeorology.org/milwaukeeidea/hbi/Archive/News/2014-May-In-Focus.pdf |title=Archived copy |access-date=2015-04-16 |url-status=dead |archive-url=https://web.archive.org/web/20160304024942/https://biometeorology.org/milwaukeeidea/hbi/Archive/News/2014-May-In-Focus.pdf |archive-date=2016-03-04 }}

=Water treatment facilities=

In Superior, Wisconsin, the city's wastewater treatment plant has installed four So-larBee units to provide adequate aeration without the use of the city's 75-hp units. After this installation, the 75-hp blower units can be completely shut off during no-flow periods. As a result, the city of Superior saved $18,000 per month.
