Methodology: How We Ranked the Best Solar Companies in Willimantic

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


Below are some the criteria we examined specifically for Connecticut 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 Willimantic

When picking a solar company, most homeowners or business owners care about the costs above all.There are quite a few factors you should take into consideration when trying to determine the overall cost and how much you can save, such as:

  • System size and type: Some models are more expensive than others, so the one you want can raise or lower your initial investment. Plus, the more solar panels you need to buy, the more it'll cost.
  • Electricity consumption: The average household in Willimantic doesn’t use much energy, and consequently may not see as many savings on their power bills.
  • The amount of sunlight your roof gets: Because of Willimantic’s high amount of average daily sunlight, you should be able to save a decent amount on your electric bills.

Solar is a profitable investment for most homeowners. You can produce your own energy instead of paying for it from a utility company and benefit from solar tax credits and rebates, all while helping preserve the planet.
