Wisconsin doubled its solar rebate for 2026, $600 per kilowatt up to $2,400, first come, first served. What it did not standardize is what your exports earn: MGE credits near retail while We Energies pays 3.6¢ flat, and that split changes how a system should even be sized. EcoGen America sorts the Dairyland rules utility by utility.
Get your feasibility score, cost estimate & installer matches.
Two 2026 facts frame every Wisconsin quote. First, the Focus on Energy rebate doubled to $600 per installed kilowatt, capped at $2,400, effective January 1, and it runs on a first-come, first-served budget: the largest direct rebate Wisconsin homeowners have had.
Second, what exports earn depends entirely on your utility. MGE in Madison credits near one-to-one retail; We Energies pays a flat 3.6¢ buyback against a 19.6¢ retail rate; Alliant and WPS sit near 3¢ avoided cost. Identical systems, wildly different answers.
At $3.11 per watt with snow-load engineering built in, and PSC-approved rate increases locked through 2027 across the major utilities, the math works, but only when the system is sized for the rules on your meter: MGE homes can size to annual usage; everyone else should size to self-consumption.
EcoGen America models your utility’s actual export rate, tracks the rebate budget, and matches you with Wisconsin’s established electrician-rooted installers.
Every installer we list is a Wisconsin shop with winters of experience, not a fly-in franchise.
Built-in checks for oversized systems on buyback utilities, missed rebate filings and dealer fees in financed totals.
MGE, We Energies, Alliant and WPS each pay exports differently. We size and model for yours.
Your information goes only to the installers you choose to hear from. Nothing is resold.
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.
This fee comes from the installer’s marketing budget and does not increase your system price. In fact, our pre-negotiated rates often save you money compared to going direct.
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, honest 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 honest.
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 honestly. 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.
