Focus on Energy solar rebate
Focus on Energy is Wisconsin’s statewide energy program, funded by participating utilities. Homeowners who buy a solar system can get $600 per kW of panel capacity, up to $2,400. That means most typical home systems reach the $2,400 cap. Your utility must participate in Focus on Energy, and the installer handles the paperwork. Focus on Energy also offers incentives for business solar projects.
Sales tax and property tax exemptions
Wisconsin does not charge sales tax on solar equipment, and the value a solar system adds to your home is exempt from property tax. Both apply automatically, so going solar does not raise your property tax bill.
Net metering in Wisconsin
Most Wisconsin utilities, including We Energies, WPS, Alliant Energy, Xcel Energy and MGE, credit the extra power your system sends to the grid. Credit rates, system size limits and monthly fees vary by utility, and some credit exported power below the retail rate. We check your utility’s current rules and size your system so you use most of what it makes.
What happened to the 30% federal tax credit?
The Residential Clean Energy Credit (Section 25D) ended for systems installed after December 31, 2025. If you buy with cash or a loan in 2026, there is no federal credit. A solar lease or prepaid lease lets the leasing company claim the 30% commercial credit and pass savings to you in the price. Read more in what changed with the solar tax credit.
