Solar Energy in Michigan: What You Need to Know
Michigan has below-average sun hours but above-average electricity rates, creating moderate solar economics. DTE Energy and Consumers Energy offer distributed generation programs.
Electricity Rates in Michigan
The average residential electricity rate in Michigan is 18 cents per kWh, which is above 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 Michigan homeowners.
Peak Sun Hours and Solar Production
Michigan averages 3.5 peak sun hours per day, which is on the lower end for the United States. However, solar panels produce electricity even on cloudy days, and the economics can still work — especially in states with high electricity rates or valuable SREC programs. A 6 kW system in Michigan produces approximately 6,132 kWh per year, accounting for standard system efficiency losses and typical weather patterns.
Michigan Solar Incentives and Programs
No state tax credit. Net metering available through DTE and Consumers Energy (various program structures). No property tax exemption specific to solar. No sales tax exemption.
Incentive Summary for Michigan
- Federal Tax Credit: 30% ITC (available through 2032)
- State Tax Credit: None
- Net Metering: Available
- SRECs: Not available
- Avg. Installation Cost: $3.10/watt (before incentives)

Environmental Impact of Solar in Michigan
Installing a 6 kW solar system in Michigan offsets approximately 5,243 pounds of CO2 per year, which is equivalent to planting 43.3 trees annually. Over the 25-year lifespan of your solar system, that adds up to roughly 131,075 pounds of avoided carbon emissions. Choosing solar energy is one of the most impactful steps a homeowner can take to reduce their carbon footprint and contribute to cleaner air in Michigan communities.
