How Much Do Solar Panels Cost in Minnesota?

The average solar panel system costs $3.11/W, including installation costs in Minnesota. For a 5 kW installation, this comes out to about $15,560 before incentives, though prices range from $13,226 to $17,894. After the federal tax credit, the average price drops by 30%

System SizeSystem CostSystem Cost (after ITC)
3 kW$9,336$6,535
4 kW$12,448$8,714
5 kW$15,560$10,892
6 kW$18,673$13,071
7 kW$21,785$15,249
8 kW$24,897$17,428
9 kW$28,009$19,606
10 kW$31,121$21,785

Your solar panel cost depends on your system’s size: while a 5 kW system will only cost you $15,560 in Minnesota, doubling the system size effectively doubles the price, so you’ll pay about twice that for a 10 kW system.

Minnesota Solar Incentives and Rebates

Some of the best solar incentives and rebates available in Minnesota:

  1. Federal Solar Tax Credit: This incentive allows solar buyers to claim a percentage of their system’s total cost. The credit is worth 30% of your total system cost. This can reduce the cost of an average-priced 8 kW system by $8,640.
  2. Minnesota Solar Sales Tax Exemption: You don’t need to pay any sales tax on new solar panel systems in Minnesota, saving at least 6.875% of your system costs.
  3. Minnesota Power Rebate: Minnesota Power customers may earn a $5,000 rebate (or 60% rebate, whichever is lower); there is a lottery system if applications exceed budget.
  4. Xcel Energy Reward: Xcel Energy customers may earn $0.02 per kWh for energy production, assuming there is enough budget.
  5. Net Energy Metering: Residents may be able to sell excess energy back to their utility provider.
  6. Minnesota Housing Finance Agency (MHFA) Fix-up Loan: This program offers homeowners the chance to upgrade their home with affordable loans. The Fix-up Loan provides $2,000 to $75,000 with fixed interest rates and repayment terms of up to 20 years.

These incentives can significantly reduce the upfront cost of installing solar panels in Minnesota. Remember, the availability and amount of these incentives can vary, so it’s important to do thorough research and possibly consult with a solar installation professional. Going solar is a big decision, but with these incentives, it can be a great investment for homeowners in Minnesota.

Is It Worth Going Solar in Minnesota?

Yes, it’s worth going solar in Minnesota. The state ranks 17th in the U.S. for solar installations. The average solar payback period is 12 years, and homeowners can save an average of $24,141 over the lifetime of their solar system. Additionally, Minnesota offers several solar incentives and tax credits.

How Much Can Solar Panels Save Me in Minnesota?

Finding out how much you can save on solar in Minnesota is not a straightforward answer. It depends on several factors, including the solar billing of your utility company, the size of a potential solar system on your roof, and your household’s energy consumption. While most solar installers will try to cover all your electricity needs, the actual savings will depend on your home’s unique conditions. To get a personal estimate of how much you could potentially save by going solar, fill out a simple form on our website, use Google’s Project Sunroof solar savings calculator, or consult with a couple of local solar installation companies for a personalized savings calculation.

Solar Financing Explained

You can pay for solar panels in a couple of ways:

  • Cash
  • Installer solar loans
  • Personal loans
  • Cash-out refinance or HELOC
  • Solar Leases or Power Purchase Agreements (PPA)

First, there is a cash purchase, which in most cases provides the best price and long-term savings, but the upfront payment is not always what you can afford. If you want to own your solar panels and don’t have about $15,000 to $20,000 in the bank, you’ll have to choose solar panel financing. 

You can consider a personal loan, a home equity line of credit, or a solar loan offered by the solar company. However, keep in mind that these loans come with interest and additional fees. Solar loans often are tied to dealer fees, which can increase the total cost of your solar system by 20% or more in exchange for a lower interest rate. To ensure you get the best possible deal, it is wise to compare the dealer fees and interest rates offered by different installers. This way, you can make an informed decision based on the most favorable terms available. 

Some companies offer solar leases or PPAs that require zero upfront cost. But in such case, you don’t own solar panels and you are not eligible for any solar rebates or the federal tax credit. And, because you have to pay the solar company monthly, your total solar savings will be lower. Ask for detailed savings calculations from a solar installer to decide on the best option. In most cases, you will still be paying less for electricity.

Our main goal is to provide homeowners like you with top-rated solar companies you can trust. Our solar experts analyzed thousands of local and nationwide installers to get to the bottom of who is best in a specific location.

In short, here’s how we pick top installers:

– Local solar companies over big national ones covering multiple areas as they can provide better personal attention and know more about the solar needs and regulations in their area.
– Companies with hands-on experience and a wealth of projects under their belt are more likely to deliver efficient and timely installations that cater to specific customer needs.
– Companies that handle their own installations instead of outsourcing to subcontractors ensure a higher caliber of work and nurture a culture of excellence and accountability in service.
– Select a company that has a good overall reputation and reviews on sites like SolarReviews, BBB, Google Maps, and Yelp.
– The company is licensed and insured and holds relevant certifications such as NABCEP certification.

What to Look for In a Solar Company

To ensure that you partner with a great provider that can meet your needs of going solar, look for the following:
– Make sure the solar installer has industry-standard certifications, such as those from the North American Board of Certified Energy Practitioners (NABCEP), indicating that they meet the gold standard in renewable energy installations. Also, verify if they are licensed, bonded, and insured for residential solar projects in your area. If subcontractors are involved, check their credentials as well.
– Prioritize installers with a proven track record in solar installations, ideally with at least 5+ years of experience. Ask about the number of systems they’ve installed and their project portfolio. A competent installer should openly discuss the solar panels, inverters, and batteries they use if they help to take advantage of local solar incentives and rebates, as well as warranty coverage specifics.
– Your installer should be forthcoming about the installation process and answer any questions you might have, like “How many solar panels will I need? Why?”, “Can you give me a detailed cost breakdown based on my energy consumption?”, “What solar panel brands do you install? Why?”, etc.. They should also be transparent about their use of subcontractors, detailing their roles and how their work will be supervised.
– A preliminary evaluation of your roof’s condition is the groundwork. The installer should advise on necessary repairs to ensure it’s ready for solar panel installation and clarify responsibilities for any potential roof damage during the process. Discuss aesthetic concerns, such as the placement of solar panels around roof vents or the possibility of relocating vents for a more visually appealing setup.
– Check the installer’s reputation through online reviews and testimonials. They should be able to connect you with past customers who are willing to share their experiences. Personal recommendations from friends or neighbors who’ve gone solar can also be invaluable.
– Solar installation costs can vary widely, so obtaining multiple quotes is advisable. Experienced installers will adjust their offers to your home’s specifics—size, energy needs, etc. For an objective cost comparison, calculate the price per watt of the proposed system, giving you a standardized basis to evaluate different quotes.

Should You Choose a Local Solar Installer or a Big National Company?

Always choose a local solar company over a big national corporation. Small local companies that operate in a distinct local area are better than multi-state and national solar companies and large corporations. It’s the small local companies who get the best reviews on our website, and it’s the national multistate companies who get very poor reviews. Why so, you may ask? 
Solar is a local service business, for the most part, and it is extremely difficult to run a solar company and offer good customer service to many locations from a central office. 
Local ones have a community connection, they know the incentives and regulations in the area better, and they simply care more about you than large businesses trying to get into your pocket and overprice you. While multi-state solar companies might try to convince you by financial stability and “quality of installations across different locations”, try to choose a local company that meets all your criteria.

What Does a Solar Installation Look Like?

Here’s how a solar system installation will look like once the design for your solar system is approved:
– First, a solar installer should estimate your energy needs, and analyze your annual and monthly electricity consumption, which you can find on utility bills measured in kilowatt-hours (kWh). Such calculations will help to understand potential savings, payback period, and the system size you need.
– A home energy audit is something every experienced solar company would do to understand the size and output needed.
– Next question on the list: are your house’s roof conditions good enough for installation? A solar installer should carefully inspect the roof and ensure its conditions and orientation are good to go, how and where to better place solar panels and wire the system.
– Next, they will design the system and show you how it’s going to look. 
You will usually need a permit to install solar panels from your local authorities, and the solar provider should handle all the paperwork.
– The entire process might take up to 3 months depending on the state and local regulations, while the system installation is usually up to 3 days (might take longer depending on roof conditions and system complexity).
– The installation crew should always clean up and remove any debris, leaving your house in good condition.
– When the system is installed, it should be checked and approved by local municipality inspection. 
– If you’re connecting your system to the grid, it has to be wired to your local utility system. You’ll apply for connection through your utility company, which will also want to inspect your system to ensure it’s following utility guidelines. Some installers may help you with this step, so always ask. Once you have all the permits, your system will be up and running, powering your home with solar.
