Complete Guide to Solar Energy in Minnesota
Your complete resource for solar energy. Everything you need to know about solar laws, solar costs, solar financing, and solar installation in Minnesota.
Why Minnesota Leads in Solar Innovation
National Community Solar Leader
Minnesota operates the nation’s most successful community solar program, with more capacity installed than any other state. This pioneering “Solar*Rewards Community” program enables renters, condo owners, and homeowners with unsuitable roofs to benefit from solar energy through virtual net metering subscriptions, democratizing access to clean energy.
Aggressive Clean Energy Mandate
Minnesota’s landmark 2023 legislation establishes the nation’s most ambitious clean energy timeline: 80% carbon-free electricity by 2030, ramping to 100% by 2040. This legally binding commitment creates long-term policy certainty, ensuring solar investments remain protected and valued throughout their operational lifetime.
Comprehensive Financial Support
Minnesota provides robust incentive stacking opportunities: complete property tax exemption on solar installations, 6.875% sales tax exemption on equipment, utility-specific performance-based incentives (Xcel’s Solar*Rewards at $0.03/kWh for 10 years), and income-qualified grants up to $3/watt for eligible households.
Strong Net Metering Framework
Minnesota statute 216B.164 guarantees net metering for systems up to 40 kW, crediting solar producers at retail rates for excess generation. While some rural utilities face legislative challenges, major urban providers like Xcel Energy maintain stable net metering policies supporting residential solar economics statewide.

Important 2026 Updates
100% Carbon-Free Electricity Mandate in Effect
Minnesota’s historic 2023 clean energy law requires utilities to provide 80% carbon-free electricity by 2030, increasing to 100% by 2040. This creates unprecedented policy stability for solar investments, ensuring 25-30 year systems remain economically valuable throughout their lifespan as Minnesota transitions away from fossil fuels. Interim renewable energy targets of 55% by 2035 further strengthen solar market demand.

Xcel Energy Rate Increases Boost Solar Value
The Minnesota Public Service Commission approved Xcel Energy’s two-year rate increases: 9.6% for 2025 ($9.89/month average residential increase) and an additional 3.6% for 2026 ($3.90/month more), totaling 13.2% over two years. These utility cost escalations accelerate solar payback periods and amplify lifetime savings, making fixed solar generation costs increasingly attractive against rising grid electricity prices.

Minnesota Solar Laws & Regulations
Federal Tax Credit
While residential solar installers no longer benefit from the federal clean energy credit, commercial installations in Minnesota may still enjoy this benefit if they begin construction latest by July 4, 2026 or become operational before the end of 2027.
HOA Solar Rights Law
Minnesota Statute 500.216 (effective July 1, 2023) prohibits homeowners associations from blocking solar installations on detached single-family homes. HOAs may establish reasonable aesthetic guidelines, but restrictions cannot increase system costs by more than $1,000 or reduce energy production by more than 10%. This “Right-to-Solar” law positions Minnesota among progressive states protecting homeowner clean energy rights.
Tax Exemptions
Minnesota provides dual tax exemptions: complete property tax exemption eliminating assessment increases from solar installations (saving thousands over system lifetime), and 6.875% sales tax exemption on all solar equipment purchases (reducing upfront costs by nearly 7%). These exemptions apply to residential, commercial, and industrial installations, significantly improving solar project economics statewide.
