Solar Panel Cost in Minnesota (2026): Price, Payback, Incentives

Q: How much do solar panels cost in Minnesota?

At the state median installed price of $3.60 per watt (estimate), a 6.4 kW (estimate) system that covers a typical home's use costs about $23,000 (estimate) before incentives. Quotes vary with roof, equipment and installer.

Solar Panel Cost in Minnesota

A typical Minnesota home uses 712 kWh a month^[1] of electricity. Covering that with solar takes a system of about 6.4 kW est.^[1,2], which costs roughly $19,500 to $26,500 est.^[1,2,3] before incentives at the state's median installed price. With Minnesota's average residential price of 16.44¢ per kWh^[4], our model puts payback at about 14 years est.^[1,2,3,4,5]. Your quote, roof and utility plan will move these numbers, so treat them as a starting point.

Incentives that lower the price in Minnesota

Federal · tax creditEnding soon

Business credit for leased and PPA systems (48E)

Claimed by the system owner, not the homeowner; solar must begin construction by July 4, 2026 or be in service by December 31, 2027^[6]

If a company owns the panels on your roof (a lease or power purchase agreement), that company may claim the business clean electricity investment credit and can reflect it in your price. You cannot claim it yourself.

Who: Third-party-owned systems (leases and PPAs). Ask the provider whether the price assumes this credit.
Deadline: December 31, 2027
Checked: November 5, 2026

How Minnesota utilities credit your solar

Under Minn. Stat. 216B.164, utilities must buy net input from small qualifying facilities; a system under 40 kW can elect to be paid for excess generation at the average retail utility energy rate (retail energy rate excluding fixed charges). Co-ops and municipal utilities fall under separate subdivision language.^[5]

We have not added every Minnesota utility yet, so the estimates on this page use the state-level rule: Minnesota net metering: exports credited at the retail rate (statewide rule; your utility's tariff may differ).

Is there still a federal solar tax credit?

Not for homeowners who buy. The Federal Residential Clean Energy Credit (25D)^[9] does not apply to systems whose installation is completed after December 31, 2025. Leased and PPA systems are different: the company that owns the system may still claim a business credit.
