Solar Panels in Minnesota: The 2026 Guide
How well solar works here, what it costs, which incentives are left, and how to decide. Straight answers from a Minnesota installer.
The short answer: solar panels work well in Minnesota. A Twin Cities system makes roughly 1,150–1,300 kWh per kW per year, and in 2026 a typical home system costs about $3.00–$3.25 per watt before incentives. The federal tax credit for homeowners ended December 31, 2025, but Minnesota still exempts solar from sales tax, Xcel pays Solar*Rewards production incentives, and net metering credits the power you send to the grid. Businesses and farms can still claim the 30% federal credit on systems placed in service by December 31, 2027.
How much sun does Minnesota get?
More than most people expect. The Twin Cities get more sunlight per year than Germany, which built one of the world’s largest solar markets. Long summer days do the heavy lifting: a south-facing array in the metro produces most of its energy from March through October and banks credits for the darker months.
- Cold helps: panels convert sunlight more efficiently when they’re cold, so a bright January day can outperform a hot July afternoon per hour of sun.
- Snow is a small loss: tilted panels shed snow quickly; annual snow losses in the metro are typically a few percent. More in our guide to solar in Minnesota winters.
- Orientation matters most: south is best, east/west roofs still produce about 80–90% as much, and shade from trees is the real enemy.
What does solar cost in Minnesota in 2026?
Independent marketplace data puts the Minnesota average at about $3.00–$3.23 per watt installed (SolarReviews 2026; EnergySage, September 2026). That is roughly $24,000–$26,000 for an 8 kW system and $39,000–$42,000 for a 13 kW system. Size, roof complexity and equipment move the number most. Our Minnesota solar cost guide breaks it down by system size, and you can sanity-check any quote with cost per watt.
Which incentives still apply?
- Minnesota sales-tax exemption: solar equipment is exempt, saving about 6.9% automatically.
- Xcel Energy Solar*Rewards: $0.05 for every kWh your system produces, paid for 10 years, on residential systems installed in 2026. Capacity is limited and first-come, first-served.
- Net metering: Xcel nets your usage and production monthly and credits surplus power, so the energy you export is worth close to what you buy.
- Battery incentives: Xcel pays $175/kWh (up to $5,000; $370/kWh income-qualified). Outside Xcel territory the state pays $250/kWh up to $7,000 while funds last.
- Businesses, farms and non-profits: the 30% federal credit plus accelerated depreciation, for systems placed in service by December 31, 2027.

How net metering works in Minnesota
Minnesota law requires utilities to net meter solar systems under 40 kW. With Xcel Energy, the power your panels make first runs your home; anything extra flows to the grid and offsets what you pull back later in the month. Surplus at the end of the month is credited and carries forward. Electric co-ops and municipal utilities follow the same law but set their own rates and fees, so the numbers differ by utility. We model your exact utility before you sign. More: net metering in Minnesota.
Rooftop solar vs. community solar
Minnesota has one of the country’s largest community solar programs: you subscribe to a solar garden and get a credit on your bill, with nothing installed at your home. It’s a good fit if you rent or your roof is shaded. If you own a sunny roof or have land for a ground mount, owning your own system typically saves several times more over its 25–30-year life, and the system adds value to your property.
Is solar worth it in Minnesota?
For most homeowners who own a sunny roof and use a typical amount of electricity, yes. Without the federal credit, typical payback in Minnesota now runs about 15–16 years on average (EnergySage, September 2026) on equipment warrantied for 25–30 years. It is shorter with higher usage, an EV, or Solar*Rewards. We wrote up the honest math in Is solar worth it in Minnesota?. Run your own numbers with the free solar calculators.

Frequently asked.
Do solar panels work in Minnesota?
Yes. A well-sited Twin Cities system produces roughly 1,150–1,300 kWh per year for every kilowatt installed. Cold weather actually helps panel efficiency, and snow typically costs only a few percent of annual output because it slides off tilted panels within days.
Is there still a federal tax credit for home solar in Minnesota?
No. The 30% federal residential credit (Section 25D) ended for systems installed after December 31, 2025. Businesses, farms and non-profits can still use the 30% commercial credit if the system is placed in service by December 31, 2027.
How much do solar panels cost in Minnesota?
Most 2026 residential installs land around $3.00–$3.25 per watt before incentives, so a typical 8–13 kW system runs about $24,000–$42,000. See our Minnesota solar cost guide for sizes and payback.
What incentives are left for Minnesota homeowners?
Solar equipment is exempt from Minnesota sales tax, Xcel customers can apply for Solar*Rewards production payments, net metering credits your exports, and there are battery incentives when you pair storage with solar. See the full list on our Minnesota solar incentives page.
Should I buy rooftop solar or join community solar?
Community solar gives you a bill credit with no installation, but you don't own anything and savings are modest. Rooftop or ground-mount solar that you own usually saves far more over 25–30 years. If your roof is shaded or you rent, community solar is a good alternative.
How long does it take to go solar in Minnesota?
Typically 6–12 weeks from signed agreement to power on: design and engineering, city permit, utility interconnection approval, a 1–3 day install, inspection, and permission to operate from the utility.
