Compare 2 Wisconsin Cities
Home solar in each city we rank: how much was installed, how many companies did it, what owned systems cost and how many homeowners leased.
| City | Home systems | Companies | Median price | Leased / PPA | With battery | #1 company |

Home systems installed in the latest three years of utility and state records for each city. Median price is for systems the homeowner bought, before incentives.
Comparing quotes in Wisconsin?
Divide each quote's total, before incentives, by the system size in watts. Ask at least three of the companies ranked in your city to quote the same system size. Reject any 2026 quote that subtracts a 30% federal tax credit from a purchase: that credit ended in 2025.

Solar Panel Repair in Wisconsin
When a system stops producing, start with an established local company: the ones ranked in each city above did the most work there in the latest records and know the equipment on local roofs. Many will service a system they didn't install, but not all — ask before you book, and expect a diagnostic fee. If your system is leased or on a PPA, call the company you pay each month first: maintenance is normally its job.

- Maintenance: cleaning, inspections and what actually needs doing.
- Damage and safety: storms, fire, roof leaks and when to shut the system off.
Installers in Wisconsin That Closed or Went Bankrupt
At least 482 home systems in Wisconsin were installed by these companies. Their panels and inverters are still covered by the manufacturers' warranties; the installer's workmanship warranty is likely gone. The city pages list the local companies still active that can take over service.
| Company | Systems in Wisconsin | What happened |
|---|---|---|
| Freedom Forever | 241 | Filed for Chapter 11 in April 2026; converted to Chapter 7 liquidation in August 2026. pv magazine USA |
| Solcius | 241 | Filed for Chapter 7 bankruptcy in February 2024. Solar Power World |
What Your Warranty Still Covers If the Installer Is Gone
- Panels and inverters: covered by the manufacturer, not the installer. Find the brand on the inverter label or in your monitoring app and contact the manufacturer directly.
- Workmanship and roof leaks: usually a promise from the installer. If the installer is in bankruptcy, that warranty may be delayed or discharged; file a claim in the case if one is open.
- Leases and PPAs: the system belongs to the finance company, and most contracts make it responsible for maintenance even if the installer that sold it is gone. Call the company you pay each month and check your contract.
- Loans: keep paying. A closed installer does not cancel a solar loan.
How Many Homes in Wisconsin Have Solar
Utilities in Wisconsin reported 19,488 homes with rooftop solar in 2026, with 172 MW of panels between them, or 8.8 kW per home on average. That is 2,411 more homes than a year earlier (+14%). Wisconsin ranks 33 of 44 states by the number of homes with solar. Home batteries paired with those systems add up to 11 MW.
Homeowners in Wisconsin pay an average of 19.56¢ per kWh for electricity, against 17.45¢ nationally. At rates this low, a typical system takes 15 years or more to pay back without the federal credit, so compare quotes carefully and ask for a production estimate for your roof. What solar costs and how long it takes to pay back.
These figures count homes enrolled in net metering or a similar program that credits the power they send to the grid, as reported by utilities. Homes on other arrangements may be missing, and a change in how a utility reports can make the numbers jump. Source: U.S. Energy Information Administration, Form EIA-861M, net metering, July 2026.
Solar in Wisconsin: Common Questions
Who installs the most solar panels in Wisconsin?
In 2023–2025, Everlight Solar installed 1,792 home systems in Wisconsin, more than any other company, followed by Arch Electric (508) and All Energy Solar (452). Volume shows experience, not workmanship, so compare quotes and reviews before choosing.
Which Wisconsin cities install the most solar?
Among the cities we rank, Madison (854 home systems) and Milwaukee (504 home systems) lead. Each city page ranks the local companies and shows prices, leasing and the installers that closed there.
Can I still get the federal solar tax credit in 2026?
Not as a homeowner buying the system: the 30% residential credit (Section 25D) ended on December 31, 2025. Be wary of any quote that still subtracts it from the price. See our 2026 solar tax credit guide for what's left.
What if my solar installer went out of business?
Your panels and inverters are still covered by their manufacturers' warranties; what you lose is the installer's workmanship warranty and service. See the installers that closed in Wisconsin and what your warranty still covers.
What do homeowners in Wisconsin pay for electricity?
Residential customers in Wisconsin pay an average of 19.56¢ per kWh, 12% above the national average. The higher the rate, the faster solar pays for itself. Source: EIA, Electric Power Monthly, Table 5.6.A.
