Are Solar Panels Worth It in Minnesota? (2026)

Conditional — solar works in Minnesota, but shop hard. — a 6.0 kW rooftop system in Minnesota pays back in about 11.1 years and delivers $10,498 in net 20-year savings after install cost and the federal tax credit. Payback is in the 10-14 year window. Getting a below-average installer price is important.

Payback11.1 yrs

Annual savings$1,176

Net install (after ITC)$13,020

20-yr net$10,498

Assumes 6 kW system at $3.10/watt (state avg), 4.2 peak sun hours/day in Minnesota, and 16.39¢/kWh electricity rate (April 2026).

The short answer

Solar in Minnesota pays back within panel warranty life but requires disciplined shopping. Prioritize installers quoting below the state average.

The 4 things that actually determine "worth it"

Electricity rate. Minnesota: 16.39¢/kWh. National avg: 18.83¢. You’re 13% below average — cheap grid electricity makes payback slower.
Sunshine. Minnesota: 4.2 peak sun hours/day. National avg: 4.5. Near average sun.
Install cost in Minnesota. $3.10/watt (state avg). Similar to national $3.00/W.
Incentive stack. Federal ITC 30% applies universally. None (state rebate program 'Solar Rewards' periodic) Net metering: Yes, 1:1 for systems <40 kW Full incentive breakdown →

Where Minnesota ranks nationally

Across all 51 states, Minnesota ranks #37 of 51 by 20-year net solar savings (1 = best). The top states are dominated by combinations of high electricity rates and high sunshine (CA, HI, MA, NY, CT). The bottom are cheap-power / cloudy-sky states (WA, OR, ID, ND).

Break-even analysis

Your solar system in Minnesota needs to save $13,020 in electricity to pay for itself. At $1,176/year savings, that’s 11.1 years. Panels are warrantied for 25 years and typically last 30+ — meaning 18.9+ years of free electricity after breakeven.

Common objections addressed

“What if I move before payback?”

Homes with paid-off solar typically sell for ~$15,000-$25,000 more than comparable homes without. If you owe money on the panels (loan), the sale is more complex. Cash or fully-paid-off systems recover most or all of the remaining "unused" value at sale.

“Won’t rates drop?”

U.S. residential electricity rates have risen ~4%/year over the past decade. Even if rates flatline, the payback above holds. If rates rise, your solar looks better in retrospect.

“What about hail / storms?”

Solar panels are rated for 1-inch hail at 50 mph. Damage claims are covered by homeowner’s insurance in almost all cases (verify with your carrier).
