Methodology: How We Ranked the Best Solar Companies in Windsor

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


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.

The Cost and Benefits of Solar in Windsor

We understand that for most homeowners, the decision to invest in solar comes down to installation costs.There are several factors you should take into consideration when trying to determine the overall cost and how much you can save, such as:

  • How much sunlight your roof gets: If your roof gets limited direct sunlight, your solar panels won’t be able to make as much energy, which will leave you with lower savings on energy bills than someone with a roof that gets a lot of sunlight.
  • Your energy bills: This will impact your savings. In Windsor, the average resident can save about $1,200 a year on their electricity bills.
  • The type of solar panels you’re thinking of getting: More efficient panels have higher prices, so that will shape your budget for your solar project.
  • How much electricity your home consumes: Homes that use lots of power each month may call for more solar panels and, therefore, more upfront cost, but will also enjoy more savings over time.

So is buying solar panels worth it? Whether you’re trying to reduce your electricity costs, carbon emissions or both, solar panels are a great investment for many Windsor homeowners.

In addition, there may be some local incentives that can save you some extra money too. Our article on solar incentives goes over more information on the incentives you can find in Windsor.

Environmental Impact of Switching to Solar in Windsor

Many want to do their part to help protect the environment, which for many is the chief reason for installing a solar system.Many homeowners might be wondering how much exactly they can impact the environment by switching to solar in Windsor, though. Something that can severely affect your carbon footprint is how long your commute is and how much you drive generally. If you go solar and drive an electric car, you can greatly decrease your carbon dioxide emissions by charging your car at home.When you go solar, your carbon footprint can be reduced by about 100 pounds every year. For those who are concerned about the environment, the upfront cost of solar is a small price to pay for offsetting your carbon emissions.

EcoWatch's Windsor, WI Solar Company Rankings FAQs

Which solar installation company is the best near me?

The highest-rated local solar company in Windsor is Full Spectrum Solar, with a rating of 5.00 stars.

Are solar panels really environmentally friendly?

Solar panels can be harmful for the environment when manufacturers use toxic chemicals when they’re made. Chemicals can make solar panels difficult to dispose of safely once they’ve reached the end of their lifespan. Making solar panels requires a lot of energy as well. The energy payback period is about 1 to 4 years.

How long does it take for solar to pay for itself?

The average payback period for solar panel installation is about 13.0 years, but the exact period depends on the cost of electricity where you are, incentives and net metering programs.

When is the best time of year to install solar panels?

Despite summer being the most common time people install solar panels, the perfect time is actually winter. You can save money since there's not as much demand during the winter months, and it allows you to be up and running with solar for the higher power bills you may get during the summer.

Our goal is to reach as many people as we can with sensible solutions like solar energy. Our team of full-time local researchers collects solar price and installation data for every city in America then compiles it to create these digestible city guides.
