Methodology: How We Ranked the Best Solar Companies in Tomah

EcoWatch's solar experts analyzed each solar company in Tomah 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 Tomah


Below are some the criteria we examined specifically for Wisconsin 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.

In addition, there may be some state and city incentives that stack with the ITC too. In our article on solar incentives, you can find out about the incentives you qualify for in your area.

Environmental Impact of Switching to Solar in Tomah

If you’re planning on adding solar panels to your home, one of the major reasons why may be to reduce your reliance on nonrenewable energy.But you may be curious – how much exactly can you help by going solar? Switching to solar power is an impactful choice for the environment, due to the fact that the largest source of greenhouse gas emissions in the U.S. is from burning fossil fuels for electricity, heat, and transportation – all of which can be powered by solar instead.Since solar panels don’t release greenhouse gas emissions into the atmosphere when producing electricity, they’re a good substitute for nonrenewable energy sources. In fact, you could be looking at reducing your carbon dioxide emissions by about 100 pounds each year. As you can see, trading traditional energy for solar has so many other benefits apart from saving money. One of the primary ones is that you can help save the planet too.
