Utility rules and programs for Duluth
ALLETE, and Lake Country Power serve St. Louis County, so which rules apply depends on your address.
| Utility | Type | Solar export rule |
|---|---|---|
| ALLETE, Inc. | investor-owned | Minnesota Power credits excess solar under its net energy metering rate at the average retail rate (2021 guide), after you apply under the state interconnection process; the simplified track costs $100 and covers 20 kW or less. Confirm current terms at 218-355-3720. |
| Lake Country Power | member-owned cooperative | Lake Country Power is a co-op, so the state under-40 kW rule applies. A third-party rate site says excess credit is paid at year end at avoided cost, which we could not confirm. |
Program details are from each utility’s own pages (read October 2026). See the Minnesota incentives table for statewide credits and a status for every program.

Solar Panel Installation in Duluth FAQs
Is solar worth it in Duluth?
The sun is strong (about 1,080 kWh a year per kW, our estimate), but export credits are low, so solar pays most when sized to what you use at home or paired with a battery. See the Minnesota incentives for the state credit.
Is there a federal solar tax credit in 2026?
No. The federal 25D credit ended for expenditures after December 31, 2025. Minnesota has no state income tax credit for home solar, but solar systems are exempt from sales tax and property tax.
Do I need a permit for solar panels in Duluth?
Usually yes, and the utility may need to approve solar and batteries. Construction Services and Inspections handles permits in Duluth; see the permit information above.
