Wisconsin doubled its solar rebate for 2026: $600 per kilowatt up to $2,400, first come, first served through Focus on Energy.
What it did not standardize is what your exports earn: MGE credits near retail while We Energies pays 3.6 cents flat, and that split changes how a system should even be sized.
On the MGE side, netting forgives; on the We Energies side, self-use carries everything and oversizing is a donation to the utility.
EcoGen America sorts the Dairyland rules utility by utility, and gets the rebate claimed while the annual budget lasts.
MGE near retail versus We Energies at 3.6 cents is a different design problem. We size for the utility on your bill.
Built-in checks for the Focus on Energy rebate claimed at 2026 rates, export math per utility, and first-come budget timing.
We track Focus on Energy budget cycles and the crediting policies that differ across Wisconsin's utilities.
Your data is only shared with the licensed Wisconsin installers you choose.
EcoGen is 100% free for homeowners. We earn a small referral fee from installers only when you choose to proceed with a project through our platform.
Wisconsin left export compensation to the utilities, and they went separate ways. This table decides your system size.
Utility | Retail Rate | Export Credit | Sizing Rule |
|---|---|---|---|
MGE (Madison) | ~18.4-19.9¢ | ~1:1 retail | Size to annual usage; exports keep full value |
We Energies | ~19.6¢ | 3.6¢ flat buyback | You lose ~16¢ on every surplus kWh; size to self-use |
Alliant / WPS | Rising ~3.5% in 2026 | ~3¢ avoided cost | Same story: daytime consumption carries the return |
Co-ops / municipals | Varies | Varies | Get the export credit in writing before contracting |
The practical rule: a Madison roof and a Milwaukee roof should not get the same design. If your installer sizes both at 110% of usage, one of you is donating power at 3.6¢.
The doubled Focus on Energy rebate runs first-come, first-served. A complete application early in the budget year is worth $2,400.
Confirm your utility's export credit in writing: near-retail at MGE, pennies most other places. It decides the design.
On buyback utilities, size to what you use as you make it; on MGE, size to your year. Snow-load racking either way.
Free 15-minute call. Budget status, utility rules, right-sizing.
Wisconsin’s flagship rebate got twice as generous this year, with a catch worth respecting.
Treat the rebate as real but bounded: it trims the entry price by up to $2,400 on a $31,000 system. The utility rules above still decide the long-term return.
Wisconsin Contract Checks
A doubled rebate attracts doubled salesmanship. Keep the paperwork tight.
A model crediting We Energies exports at retail inflates savings five-fold. The utility and its actual buyback belong in the projection.
On buyback utilities, oversizing donates margin. Only MGE-style crediting justifies sizing to full annual usage.
Focus on Energy money is real only if the budget holds and the filing is clean. Who files, when, and who bears a miss belongs in the contract.
At $3.11/W with snow engineering, Wisconsin is not cheap; dealer fees make it dishonest.
Four lines, any Dairyland quote. The electrician-rooted shops answer them cold.
Vetted for licensing, winter engineering, rebate fluency and complaint history.
Good rebate, real winters, split rules. These cases should wait or redesign.
Green lights: MGE customers almost categorically, and high-daytime-use homes on any utility who can land the rebate and size the system right. Run your scenario in our worth-it breakdown.

$600 per installed kilowatt through Focus on Energy, capped at $2,400, double the 2025 level, effective January 1, 2026.
It runs first-come, first-served on an annual budget: file early and completely, and put the filing responsibility in your contract.
It depends entirely on your utility. MGE credits exports near one-to-one retail; We Energies pays a flat 3.6¢ buyback; Alliant and WPS sit near 3¢ avoided cost; co-ops vary.
That split is why identical systems in Madison and Milwaukee should be sized differently.
To your self-consumption, not your roof: surplus earns 3-4¢ while offset usage saves 15-20¢. Shift what load you can into daylight and size to that.
Only near-retail crediting, like MGE’s, justifies sizing to full annual usage.
About $3.11 per watt installed, $16,400 to $41,800 across common sizes, with snow-load engineering part of the price.
The rebate trims up to $2,400; rate increases locked through 2027 do the rest of the work over time.
