Solar Panel Cost in Minnesota (2026 Estimate)

Data last updated September 10, 2026 · ranks #30 of 50 states for modeled payback

Minnesota averages about 4.3 peak sun hours a day (below the national average) with an approximate residential electricity rate near 15¢/kWh, in the mid-range nationally. In the model used here, an 8 kW system in Minnesota produces roughly 10,040 kWh a year and trims about $1,500 off annual electricity costs, paying back its net cost in about 11.2 years. That is a middle-of-the-pack payback, so whether solar is worth it in Minnesota often comes down to your specific rate, roof, and any state or utility incentives.

Estimated system cost and payback in Minnesota

Costs assume roughly $3.00/watt installed for Minnesota; the net column applies a 30% federal credit for comparison with quotes that include it. Savings and payback use the state's sun hours and rate above.

The 30% federal Residential Clean Energy Credit ended for systems paid for after December 31, 2025 under the 2025 federal budget law. Net-after-credit figures apply only if you still qualify (for example a 2025 expenditure, or a leased system where the installer passes a credit through). Confirm with a tax professional.

What moves the numbers in Minnesota

Two inputs drive most of the difference between states: how much sun a system sees and what each offset kilowatt-hour is worth. Minnesota's 4.3 sun hours set production, and its roughly 15¢/kWh rate sets what that production saves. The bigger unknowns are your roof, shading, and how your utility compensates exported power, since a lower export rate can pull real savings below the retail-rate figure above.

Net metering and export credits in Minnesota

Minnesota was the first state to require net metering, and the statute still covers every utility, including cooperatives and municipal systems. Systems under 40 kW at investor-owned utilities are credited at the retail rate, and a homeowner can choose either to roll surplus forward as a bill credit or to be paid for it monthly. Co-ops and munis must offer net metering too, though many of them apply their own fixed monthly fees to solar customers, which the legislature permitted and which can noticeably trim savings.

The state pioneered the "value of solar" methodology in 2014 as an alternative to net metering, but as of 2026 Xcel Energy uses it only for community solar garden subscriptions, not for rooftop arrays. Systems between 40 kW and 1 MW at the investor-owned utilities fall under different compensation rules, so this matters only for a very large residential or farm installation.

Minnesota solar incentives beyond the federal credit

Xcel Energy customers can apply for Solar*Rewards, a performance-based payment per kilowatt-hour over ten years for systems under 20 kW, with a higher payment tier for income-qualified households. Funding is allocated annually and applications open in waves, so the program can close partway through a year; check availability before you count on it. Minnesota Power and some co-ops have run their own smaller rebate programs in the past, and several co-ops still offer them intermittently.

Solar equipment is exempt from state sales tax, and the value of a residential PV system is excluded from property tax under state law. Minnesota also has no statewide solar income tax credit, so the combination of net metering, Solar*Rewards where available and the federal credit makes up the full picture.

Utilities and rate plans in Minnesota

Xcel Energy is by far the largest provider, serving the Twin Cities and much of southern Minnesota, while Minnesota Power covers the Duluth and Iron Range region and Otter Tail Power serves the west. The remaining customers are split among municipal utilities and roughly four dozen rural electric cooperatives supplied by Great River Energy and other generation-and-transmission co-ops. Xcel residential rates sit near the national average, and its optional time-of-use plan can raise or lower solar value depending on when a household uses power. Co-op customers should ask specifically about the fixed monthly charge for distributed generation before signing a contract, since it is the single biggest variable in Minnesota solar economics.
