Methodology: How We Ranked the Best Solar Companies in Windom
EcoWatch's solar experts analyzed each solar company in Windom based on criteria such as its reputation in the industry, customer reviews, services, warranty coverage and financing. Using this solar methodology, we used the data we collected to rate and rank each company and narrow down our picks for the best solar companies in Windom
Below are some the criteria we examined specifically for Minnesota solar companies
- Brand reputation and certifications (20%): We take each company's Better Business Bureau (BBB) score into consideration, as well as how long the installer has been in business (at least 5 years is required, 10 preferred) and what type of solar certifications it holds.
- Customer reviews (20%): Trust is a top priority at EcoWatch, so we take customer experience under close consideration. We scour different review sites and customer testimonials when ranking our top solar companies, checking sites such as Trustpilot and Google Reviews. We also consider any potential complaints or lawsuits filed against these companies and award or remove points accordingly.
- Warranty (20%): A company earns a perfect score in this category if it offers 25-year warranties that cover performance, product and workmanship. The industry standard that we measure companies against is 25-year product and performance warranties, along with a 10-year workmanship warranty. We also look closely into the track record of the post-installation support each company provides in terms of honoring its contracts
- Solar services (10%): All of the companies we review install solar panels, but we award companies higher points if they offer additional services for customers, like battery installation, energy-efficiency audits, and EV chargers.
- Pricing and financing (10%): It's hard to get exact quotes for solar projects, but we use marketplace research to determine how each company prices its equipment and installation services. Additionally, companies that offer more help for panel financing — like in-house loans, leases, or PPAs — score higher than those that don't.
- Availability (10%): The bigger the service area, the higher the company will score.
- Transparency and accessibility (5%): Solar installers that offer free consultations and easy contact methods score higher in this category.
- Environmental, social and corporate governance factors (5%): A company earns a perfect score in this category if it offers public data disclosure, addresses end-of-life (EOL) products or processes, and demonstrates a commitment to uplifting the communities that it serves.
The Cost and Benefits of Solar in Windom
For lots of homeowners, the decision to invest in solar energy boils down to the cost. Some significant things that influence the upfront cost and potential savings over time include:
- The type of solar panels you can afford: This depends on how much you're willing to spend upfront.
- Incentives: The federal solar investment tax credit, which everyone qualifies for, allows you to deduct 30% of the cost of your solar system installation from your federal taxes. In addition, not including incentives, you can save about $16,000 over 20 years on your energy bills.
- How much energy costs for you: If your local electricity rates are quite high, there's a better chance you'll get a higher return on your investment in solar panels. In Windom, you can save an average of $97 a month on your electricity bills.
- How much power your household needs: If your home needs to use a lot of energy, you'll benefit more from installing solar panels.
There are many great benefits of solar despite the upfront cost of installation. It can help the environment and your bank account. Plus, it can boost the value of your home, giving you even more benefits if you decide to sell your home later.

Environmental Impact of Switching to Solar in Windom
Installing solar panels is a good way to do what you can for a more eco-friendly future. Something many might be wondering about is how much can they really help the environment by switching to solar power anyway? According to the EPA, electricity generation is the second biggest source of greenhouse gas emissions and about 62% of our electricity is produced by burning fossil fuels. Switching to a clean energy source like solar power can help lower that statistic in a city like Windom that produces a large amount of carbon dioxide emissions each year. When you go solar, your carbon emissions can be reduced by about 90 pounds every year. The perks of solar power are abundant — just like solar power is! That's why so many people have been happy with committing to solar.
