How Does the Federal Solar Tax Credit Work?

In addition to the incentives above, Minnesota homeowners can use the federal solar tax credit, also known as the solar Investment Tax Credit (ITC). This incentive reduces your federal government taxes by up to 30% of your total solar panel installation costs. The policy was introduced as part of the Energy Policy Act of 2005 and was initially set to expire in 2007, but Congress has extended it multiple times. It’s currently set to run through 2034, though the rate will begin to reduce in 2033. Learn more about this incentive in our guide to the federal solar tax credit.

Does Minnesota Offer Net Metering?

Minnesota is one of several states with net metering laws, also called interconnection laws. 

These laws allow you to sell excess energy your solar panel system generates back to the power grid. Minnesota residents can choose to receive a standard compensation rate per kW or a credit applied to future electricity bills.

How Much Do Solar Panels Cost in Minnesota?

It costs an average of $17,150 to install a standard 5-kW solar panel system in Minnesota.* This aligns with the national average cost of solar panels. A solar installer will most likely charge based on the wattage, with the average price being $3.43 per watt. Using the federal tax credit would reduce this price by $5,145.

It’s important to note that your selected payment method impacts your total price. We researched and analyzed each of the popular solar financing options to help you make the best choice for your budget and needs.

• Cash purchase: An up-front payment is the most cost-effective option. Paying in full eliminates the need for interest rates, credit checks, and extra fees. This payment option also gives you full system ownership, qualifying you for all solar incentives.
• Solar loan: This is the second-best payment option. It eliminates high up-front costs, instead requiring monthly payments toward system ownership. You’ll also qualify for solar incentives to help reduce your investment, though you’ll pay more in the long run due to interest rates.
• Solar lease: A solar lease is the best financing option for homeowners who don’t qualify for loans or can’t afford a large cash payment. Be aware that a solar lease disqualifies you from using solar incentives because the solar company remains the system’s owner. You should also know that a leased system does not increase your home’s value like a cash purchase or loan.
• Power purchase agreement (PPA): You can think of a PPA as if you’re still paying your regular electricity bill but for solar energy instead of grid-tied power. A contract outlines your expected rate, which will be lower than the standard electricity rate. Many solar companies include maintenance and repairs with PPAs. However, you don’t own the system and are thus disqualified from using solar rebates or other incentives.

How long does it take for solar panels to pay for themselves in Minnesota?
