Federal solar tax credit (Section 25D, ended for 2026 purchases)
The 30 percent federal residential tax credit (Section 25D) applied through December 31, 2025 and is not available for a purchased home system placed in service after that date, so most 2026 homeowner purchases cannot claim it. If you go solar through a lease or a power purchase agreement, the provider may still claim the business version of the credit (Section 48E) and pass part of the value through in your rate. Confirm your eligibility with your installer and a tax advisor.
Minnesota Solar Equipment Sales Tax Exemption
Minnesota exempts solar energy systems from state sales and use tax under Minn. Stat. 297A.67, Subd. 29. This applies to the equipment used in a qualifying solar energy system as defined in Minn. Stat. 216C.06. The exemption reduces the upfront cost of your system by eliminating the 6.875 percent state sales tax on qualifying solar equipment purchased and installed in Minnesota. Your installer confirms which components qualify.
Minnesota Solar Equipment Property Tax Exemption
Residential solar energy generating systems are exempt from Minnesota property tax under Minn. Stat. 272.02, Subd. 24. This means adding a rooftop solar system does not increase the assessed value of your home for property tax purposes, so your annual property tax bill stays the same after installation. The exemption applies to personal property consisting of a qualifying solar energy generating system.
Net metering: Net metering (Minn. Stat. 216B.164, PUC-regulated investor-owned utilities)
Minnesota requires its electric utilities to offer net metering under Minn. Stat. 216B.164. Residential systems up to 1,000 kW served by investor-owned utilities (and up to 40 kW for cooperatives and municipal utilities) are eligible. Excess generation your panels send to the grid is credited as kilowatt-hour credits on your bill and carries forward month to month, resetting annually. Utilities may not impose standby charges on qualifying systems of 100 kW or less without PUC approval. Xcel Energy is the largest utility in the state and administers net metering for most Twin Cities customers; Minnesota Power serves the Duluth and Iron Range area. Your installer confirms the current net-metering tariff and credit rate for your specific utility before the project is quoted.

Frequently asked questions
How much do solar panels cost in Minnesota?
A typical Minnesota home solar system runs around $2.90 per watt installed, so a 7.5 kW system costs roughly $21,750 before incentives. Minnesota exempts solar equipment from state sales tax (6.875 percent), saving several hundred dollars on the purchase. The 30 percent federal residential tax credit (Section 25D) ended for systems placed in service after December 31, 2025, so most 2026 homeowner purchases cannot claim it. Your actual quote depends on roof type, shading, and the installer you choose.
What solar incentives are available in Minnesota?
Minnesota provides two strong state-level benefits: solar equipment is exempt from the state sales tax under Minn. Stat. 297A.67, and a solar system does not increase your home's assessed value for property tax under Minn. Stat. 272.02. On the billing side, Minnesota law (Minn. Stat. 216B.164) requires utilities to offer net metering, so excess power your panels send to Xcel Energy or Minnesota Power credits your future bills. The 30 percent federal Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, so most 2026 homeowner purchases cannot claim it; if you go solar through a lease or PPA the provider may still pass through part of the business credit. Confirm what applies with your installer and a tax advisor.
Is solar worth it in Minnesota?
For most Minnesota homeowners, yes. A 7.5 kW system at current costs typically pays back in around 10 years using state tax savings and net metering credits, then continues producing for 15 or more years after that. Minnesota summers deliver solid solar production, and cold winter temperatures actually help panels run more efficiently than they do in hot climates. We connect you with vetted installers who model your specific roof, utility rate, and usage so you can see the real numbers before committing.
Does Minnesota have net metering?
Yes. Minnesota law (Minn. Stat. 216B.164) requires electric utilities to offer net metering to qualifying solar customers. Excess power your roof generates is credited on your bill as kilowatt-hour credits that carry forward month to month and reset annually. Investor-owned utilities such as Xcel Energy administer net metering under PUC oversight. Your installer confirms the credit rate for your utility and tariff before the project is quoted.
