Solar Energy in Minnesota: What You Need to Know
Minnesota has decent solar resources and a strong community solar market. Xcel Energy's Solar Rewards program has driven significant adoption. Cold temperatures actually improve panel efficiency.
Electricity Rates in Minnesota
The average residential electricity rate in Minnesota is 14.5 cents per kWh, which is below the national average of approximately 16 cents per kWh. These moderate rates provide a reasonable foundation for solar savings. Combined with the federal tax credit and any state incentives, solar remains a strong investment for most Minnesota homeowners.
Peak Sun Hours and Solar Production
Minnesota averages 4 peak sun hours per day, which is moderate but still viable for residential solar. Many successful solar installations operate across the Northeast and Midwest with similar sun hours. Modern panels are increasingly efficient even in diffuse light conditions. A 6 kW system in Minnesota produces approximately 7,008 kWh per year, accounting for standard system efficiency losses and typical weather patterns.
Minnesota Solar Incentives and Programs
No state tax credit. Xcel Energy Solar Rewards program (declining incentive). Net metering available statewide. Sales tax exemption on solar equipment. Property tax exemption for solar. Strong community solar gardens program.
Incentive Summary for Minnesota
- Federal Tax Credit: 30% ITC (available through 2032)
- State Tax Credit: None
- Net Metering: Available
