Federal credits ended for systems placed in service on or after January 1, 2026 (Public Law 119-21). There is no phase-down and no partial credit.
In Wisconsin, the incentives that still matter are state weatherization rebates or tax exemptions, utility-level programs, and local efficiency incentives. Net-metering or export-credit rules set by your utility also affect savings.
Because these incentives vary by state, utility, and locality, your savings math is local rather than federal. The authoritative, regularly-updated list for any state is DSIRE.
Where to look for Wisconsin-specific incentives
Check DSIRE for the latest Wisconsin state, utility, and local programs and how they apply to your home.
Your utility’s website or customer service can confirm net-metering or export-credit details and any available rebates or incentives.
Local governments and utility-sponsored programs may offer energy-efficiency rebates or exemptions that can significantly reduce costs during weatherization and upgrades.
