How Much Do Solar Panels Cost in Minnesota? (2024) – MarketWatch

As mentioned above, Minnesota residents who switch to solar power will pay $2.98 per watt of installed capacity or $2,980 per kilowatt.

The following table provides estimated installation costs for home solar systems ranging from 5 kW to 10 kW, along with net prices after you apply the 30% federal solar tax credit.

*Average solar prices are based on state research conducted by the MarketWatch Guides team. Actual costs will vary depending on your home’s roof complexity and other site conditions.

To make sure your solar power system is properly sized and installed, we recommend contacting a solar installation company. Professional installers will calculate an optimal system wattage based on an assessment of your monthly energy bills and roof conditions.

Your system capacity is the main factor that determines the cost of a solar panel array. Homes with increased energy consumption will need a larger solar array to offset monthly electricity bills.

However, you can lower the net cost of a solar system if your local government or utility company offers financial incentives for installing renewable energy technology. Below we discuss the main elements that factor into how much it costs to go solar in Minnesota.

• Your home energy consumption: According to the Energy Information Administration’s Residential Energy Consumption Survey, homes in the West North Central region of the U.S. have an average electricity usage of 10,697 kilowatt-hours (kWh) per year. To generate this energy output with Minnesota’s sunshine conditions, you would need a solar system capacity of around 8 kW. A solar panel system of this size costs around $23,840, which drops to $16,688 after the 30% federal tax credit. Your system size and price will vary if you require more or less capacity.
• Additional services and equipment: The cost of your solar project will increase if you add other components, such as a solar battery or an electric vehicle (EV) charger. The cost figures included in our guide only include solar panels and basic components like the inverter, wiring and racking. For example, solar batteries can add upwards of $10,000 to your system price.
• Local net metering policies: Net metering is an electricity billing method that favors solar panel owners. When your solar generation exceeds your consumption, you can send excess energy to the grid for power bill credits. The Minnesota Public Utilities Commission (MPUC) has a favorable net metering policy in which solar systems up to 40 kW in size receive full credit for excess energy sent to the grid.
• Solar rebate programs and tax incentives: Minnesota offers a sales tax exemption and property tax exemption for solar energy systems. Depending on your electric company, you can claim additional incentives. For example, Minnesota Power customers can take part in an annual rebate lottery, which offers up to $5,000 for home solar installations. Xcel Energy customers can also qualify for an energy production incentive. Plus, you can combine local solar incentives with the 30% federal tax credit.

Minnesota offers several incentives for solar panel systems, summarized in the chart below:

Minnesota also offers incentives for energy efficiency measures and other renewable energy sources beyond solar power. The Database of State Incentives for Renewables and Efficiency (DSIRE) has an updated list of energy incentives in Minnesota.

We at the MarketWatch Guides team have reviewed and ranked the best solar companies nationwide and in Minnesota based on industry research and in-depth analysis. Our picks for the top installers in Minnesota include:

All four companies offer solar financing options like solar loans and leases so homeowners can install a solar system at little to no upfront costs.

We believe that solar panels can be worth it for Minnesota homeowners. Minnesota offers multiple incentives for home solar systems, combined with a fair share of annual sunshine to boost energy production. Minnesotans who go solar can achieve an attractive return on investment:

• You can expect to pay $17,880 for a 6 kW photovoltaic system in Minnesota.
• After the 30% federal tax credit, the net price of this system drops to $12,516.

If you have a site with favorable sunshine conditions, a 6 kW solar system can generate around 8,000 kWh of energy per year. According to the EIA, Minnesota has an average residential rate of 15.45 cents per kWh. Based on this example, 8,000 kWh of solar electricity represents $1,236 in annual energy savings. At an upfront system cost of $12,516 after incentives, your payback period would be 10.1 years.

A 10-year payback period may seem long, but the lifespan of high-quality solar panels is much longer. The best solar panel brands can last two to three decades and offer 25- to 40-year product warranties to cover performance issues over time.

Plus, you can achieve a shorter payback period if you qualify for the Xcel Energy Solar*Rewards program or the Minnesota Power SolarSense program.
