How Brookfield compares

Net metering, tax credits and incentives in 2026

Wisconsin offers net metering: power you send to the grid is credited at or near the retail price, so every solar kWh is valued at 19.0¢ here.

There is no federal tax credit for buying home solar installed in 2026. The 30% Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, so the costs and paybacks on this page include no federal credit.

Wisconsin and local utilities may still offer rebates, performance payments, property-tax or sales-tax exemptions. Search the DSIRE incentives database for Wisconsin and ask installers which programs they apply for you.
