How this number is built
We start from a 2026 national baseline for solar panel installation and apply a Minnesota cost factor of 1.04, which reflects local labour, permitting and material costs. That puts Minnesota 4% above the national average — ranked #37 of 51 from cheapest to most expensive.
Solar is priced at roughly $2.70 per watt installed here. Minnesota electricity runs 14.8¢/kWh, which is what determines how quickly a system pays for itself.
The federal solar tax credit no longer applies. Section 25D expired December 31, 2025, so a cash or financed purchase in 2026 gets no federal credit — only third-party-owned (lease/PPA) systems still reach one indirectly. Every figure on this page is gross, before any state or utility incentive.
What moves the price
- Roof area and how many panels physically fit
- Roof pitch, orientation and shading
- Panel efficiency and inverter type
- Electrical panel upgrades, if needed
