Utility rules and programs for Plymouth
Xcel Energy (Northern States Power) and Wright-Hennepin Cooperative serve Hennepin County, so which rules apply depends on your address.
| Utility | Type | Solar export rule |
|---|---|---|
| Northern States Power Co – Minnesota | investor-owned | Xcel Energy is rate-regulated, and Minnesota law (216B.164) requires net metering for systems under 1,000 kW: monthly surplus is credited at the average retail utility energy rate or the simultaneous purchase and sale rate, and any year-end balance is paid at the applicable rate (guides call this avoided cost, so confirm). Your installer files the application through Xcel’s online solar portal. |
| Wright-Hennepin Coop Elec Assn | member-owned cooperative | Wright-Hennepin is a co-op, so the state under-40 kW rule applies: net metering with either a per-kWh payment or credits that cancel at year end. We did not find its tariff online; confirm before you buy. |
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 Plymouth FAQs
Is solar worth it in Plymouth?
The sun is strong (about 1,110 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 Plymouth?
Usually yes, and the utility may need to approve solar and batteries. Building Inspections (City of Plymouth) handles permits in Plymouth; see the permit information above.
