Run the numbers — your payback estimate
Answer three questions about Minnesota; nothing is saved or sent. Adjust any number — every formula is shown below.
What we assumed (and how to adjust it)
Sun in Minnesota: Moderate sun resource sun resource. The estimator starts from the national U.S. rule of thumb of ≈1,200 kWh generated per installed kW per year — high-sun states produce more, low-sun states less.
The 30% federal Residential Clean Energy Credit is applied only if you tick the 2025-install box — it is not assumed for new installs (IRS, accessed 2026-08-08). The system is sized to roughly 100% of the annual usage you enter, so monthly savings ≈ your bill. Simple payback = net cost ÷ annual savings. Rate inflation, roof work, financing and batteries are ignored.
Planning math only — a real quote is the only number that matters. Federal-credit rule sourced from the IRS on 2026-08-08; the yield rule of thumb has no citation yet and is marked in review.
Minnesota pairs a 1983-era net metering rule (retail credits, monthly rollover) with the country's most successful community-solar 'solar garden' movement and a utility solar mandate - an unusually friendly solar policy in the north.
Costs and incentives
- verified 2026-08-08Minnesota has had a net metering rule since 1983: systems up to 40 kW net-meter with monthly rollover of surplus, and the 2013 law raised eligibility to 1 MW and required investor-owned utilities to reach 1.5% solar by 2020, on top of a 25%-by-2025 renewable standard. — Wikipedia 'Solar power in Minnesota' — accessed 2026-08-08
- verified 2026-08-08Minnesota's community solar 'solar garden' program, begun in 2013, is the largest per-capita community-solar fleet in the U.S. - announced gardens alone totaling around 200 MW of potential, later exceeding 500 MW as subscriptions grew. — Wikipedia 'Solar power in Minnesota' — accessed 2026-08-08
- verified 2026-08-08A state resource analysis puts Minnesota's rooftop solar potential at 38.5% of statewide electricity consumption (about 23,100 MW of rooftop panels). — Wikipedia 'Solar power in Minnesota' — accessed 2026-08-08
- verified 2026-08-08The average residential installation cost in Minnesota was about $3.07 per watt in 2021 (a typical 5 kW system producing ~7,300 kWh/year cost roughly $15,350), and prices have kept falling since. — Wikipedia 'Solar power in Minnesota' — accessed 2026-08-08
The 30% federal Residential Clean Energy Credit applied to qualifying systems in service by December 31, 2025 — per the IRS, property placed in service after that date does not qualify, so most 2026 installs can't claim it. State and utility programs change often; the notes above carry their verification date. See the federal credit guide.

How to buy solar in Minnesota — the honest version
- Model the math first. Get 2–3 quotes in $/W (dollars per watt, before credit) and compare on that number — not on "savings" projections.
- Check your utility's export rules. Retail net metering vs net billing changes whether you want a battery.
- Ask about the hidden three: permits, HOA rules and roof condition — before you sign.
