Solar Panels in Minnesota: Cost, Payback & ROI (2026)

Is solar still worth it in Minnesota after the 30% federal tax credit expired? These pre-computed estimates use NREL PVWatts production data and current 13.8¢/kWh Minnesota electricity rates for a typical home using 900 kWh/month.

Section 25D (30% federal solar tax credit) expired December 31, 2025

All numbers below reflect 2026 math with no federal residential credit. State incentives, where applicable, are noted in the section below.

Is Solar Worth It in Minnesota in 2026?

Minnesota's 13.8¢/kWh average rate and moderate solar resource create reasonable solar economics, particularly for Xcel Energy customers who have access to the Solar*Rewards program. Minnesota's Value of Solar Tariff (adopted by Xcel in certain areas) compensates customers based on a complex formula that may value solar differently than a simple retail rate.

For a typical Minnesota home consuming 900 kWh per month, our calculation shows a 8.6 kW system needed for 100% offset. At the current national average installed cost of $2.95/W (LBNL Tracking the Sun 2024), that's $25,488 gross before any state rebates. Year-one savings of $1,490 grow each year as electricity rates escalate — the model assumes 2.5%/year (EIA AEO 2024).

The 14.9 years payback period is moderate — within the national average range of 8–12 years. Over 25 years — the standard warranty period for most premium panels — a Minnesota homeowner following this profile would save an estimated $47,662 total, for a net benefit of $22,174 after recovering the system cost.
