Solar Incentives in Wisconsin (2026)
The 30% federal tax credit for purchased home solar ended Dec 31, 2025. Here's exactly what solar incentives are left in Wisconsin in 2026 — and how much they're worth.
| State tax credit | None |
|---|---|
| SREC market | No |
| Net metering | Retail net metering (1:1) — see Wisconsin net metering → |
| Other incentives | No state tax credit, but Focus on Energy pays cash-back rewards and solar is exempt from sales tax and added property-tax value. |
Incentive details reflect programs active in 2026. Programs change and often have caps or waitlists — always confirm current status on DSIRE and with your installer.
Federal credit status (2026): the 30% residential clean-energy credit (Section 25D) was repealed for systems purchased and placed in service after Dec 31, 2025 — cash and financed buyers can no longer claim it. A leased or PPA system can still access the commercial credit (Section 48E), which its owner can claim through 2027 and may pass on as a lower price. That makes Wisconsin's state and utility incentives, not the federal credit, the main lever on your 2026 payback.
How much can you actually save in Wisconsin?
A typical 8 kW install in Wisconsin costs about $22,000 before incentives. Wisconsin has no state income-tax credit, so your savings come from retail net metering (1:1), and the specifics below: No state tax credit, but Focus on Energy pays cash-back rewards and solar is exempt from sales tax and added property-tax value. With the 30% federal credit gone for purchases, these state and utility programs — plus your avoided electricity cost at ~19¢/kWh — are what now determine payback.

Does Wisconsin have an SREC market?

Can I still get the 30% federal solar tax credit in Wisconsin?
Not if you buy the system. The federal residential (25D) credit was repealed for purchases placed in service after Dec 31, 2025. A leased or PPA system can still tap the commercial (48E) credit its owner claims through 2027, which may show up as a lower rate — but you won't file for 30% yourself on a cash or financed purchase.
