What solar panels cost in Minnesota in 2026
Solar is priced per watt of panel capacity. We looked at 40 home solar contracts Wolf River Electric signed in Minnesota from June through October 2026, all roof-mounted systems without a battery, ground mount, trenching or panel upgrade. The middle half came in between $2.70 and $3.15 per watt, with a median of about $2.93. Most systems were 8 to 12 kW, and the median price was about $27,600.
| System size | Good fit for | Typical price before incentives |
|---|---|---|
| 6 kW | Smaller homes, low usage | $16,200 to $18,900 |
| 8 kW | Average usage, gas heat | $21,600 to $25,200 |
| 10 kW | Larger homes or an EV | $27,000 to $31,500 |
| 12 kW | High usage | $32,400 to $37,800 |
| 15 kW | Electric heat or two EVs | $40,500 to $47,300 |
Ranges use $2.70 to $3.15 per watt. Batteries, ground mounts, trenching and electrical panel upgrades add to the price. For comparison, EnergySage’s October 2026 Minnesota average is $3.24 per watt for a 12.6 kW system. We size every system from 12 months of your electric bills, not from a chart.
What changed in 2026: the federal tax credit
The 30% federal tax credit for homeowner-owned solar (Section 25D) ended for systems installed after December 31, 2025. If you buy a system with cash or a loan in 2026, there is no federal credit to subtract from the price.
Two things still apply:
- Solar leases and prepaid leases. The leasing company can still claim the 30% commercial credit and pass the savings to you in the price. A prepaid lease is now the main way homeowners get savings tied to that credit.
- Systems placed in service in 2025. The credit applies to your 2025 federal return. If you missed it, ask a tax professional about amending.

Minnesota incentives that lower your cost
- Net metering. Every Minnesota utility, including co-ops and city utilities, must offer net metering for home systems under 40 kW. Power you send to the grid earns a credit on your bill. Rates and fees vary by utility.
- Xcel Energy Solar*Rewards. Xcel customers can enroll in Solar*Rewards, which pays $0.05 per kWh your system produces for 10 years on 2026 enrollments.
- No sales tax. Home solar equipment is exempt from Minnesota sales tax.
- No property tax on the added value. The value solar adds to your home is exempt from Minnesota property tax.
See every program, utility by utility, in our Minnesota solar incentives guide.
What affects the price of your system
- System size. The bigger the system, the higher the total price, but the lower the price per watt usually gets.
- Roof or ground mount. A roof in good shape with a south, east or west face is the simplest install. Ground mounts cost more but work well on farms and acreages. If your roof needs replacing soon, do it first.
- Equipment. Panel brand and efficiency, and microinverters versus a string inverter, change the price and the warranty.
- Electrical work. Some homes need a main panel upgrade before solar or a battery can connect.
- Battery backup. A home battery adds to the cost and keeps essentials running in an outage. We quote every system with and without one.
How long it takes to pay off solar in Minnesota
EnergySage’s October 2026 data puts the average Minnesota payback at about 14.5 years, based on its $3.24 per watt average. A lower price shortens it. Payback is shorter when you use more power, pay a higher rate, have a roof that faces south, or receive Solar*Rewards payments. It is longer for small systems on shaded roofs.
The simple math: your net cost divided by what solar saves you each year, plus any production payments. We run this with your actual bills and your utility’s credit rules, so you see your own payback, not a state average. For the bigger picture, read are solar panels worth it in Minnesota?
Ways to pay for solar
- Cash. The lowest total cost over the life of the system.
- Solar loan. Little or nothing down. Your loan payment replaces part of your electric bill.
- Lease or prepaid lease. The leasing company owns the system and claims the commercial tax credit. See our Solar Price Reset offer for how a prepaid lease works.
Minnesota solar cost questions
How much does a 10 kW solar system cost in Minnesota?
Most 10 kW roof-mount systems we install in Minnesota cost about
7,000 to $31,500 before incentives, based on our 2026 contracts.
Is there still a federal tax credit for solar in 2026?
Not for systems homeowners buy with cash or a loan. The 25D credit ended after 2025. Leases and prepaid leases can still pass along savings from the commercial credit.
Does solar raise my property taxes in Minnesota?
No. The value a solar system adds to your home is exempt from Minnesota property tax, and the equipment is exempt from sales tax.
Do solar panels work in a Minnesota winter?
Yes. Panels make less power in December and January, but they run efficiently in cold, clear weather and make most of their power from spring through fall. Net metering credits help even out the year.
