Everything Minnesota homeowners need to know: costs, incentives, net metering policy, and what makes this state unique for solar.
Quick answer
Minnesota solar economics depend mainly on 4.5 average peak sun hours, an estimated $2.95/W installed cost, 14.0¢/kWh electricity, and the state's current net-metering rules.

State-specific decision guide
What to verify before signing a Minnesota solar quote
In Minnesota, the financial result depends on more than sunshine or the headline installation price. Confirm the export rule, program eligibility date, and interconnection timeline for your exact utility before treating a payback estimate as a promise.
Export value
This page models full retail net metering. Ask which tariff and export credit apply to your account, not only which program name appears in the proposal.
Incentive eligibility
Check equipment, income, installer, application, and placed-in-service rules before subtracting an incentive from the quote. Programs can close or change terms.
Interconnection
Budget for the published 4–8 weeks and confirm who pays for a required meter, service upgrade, or engineering review.
Source trail: production assumptions use NREL PVWatts; incentive discovery should be checked against DSIRE; electricity-market context is available from the EIA. Confirm final tax treatment with the IRS and your utility.
