Methodology: How We Ranked the Best Solar Companies in Thomaston

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


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 Thomaston

For a lot of homeowners, whether or not you should invest in solar panels boils down to the cost. The cost and possible savings vary depending on some important factors such as:

  • Typical energy usage: The more power your household uses on average and the higher your current power bills are, the more benefits you'll see from going solar.
  • Your income and budget: This guides what kind of solar panels you can buy.
  • The cost of energy for you: If your local power rates are quite high, there's a better chance you'll have a higher return on your investment in a solar system. In Thomaston, you can save an average of $90 a month on your electricity bills.
  • Incentives: The federal solar investment tax credit currently allows you to reduce your taxes by 30% of the project cost. Your state and city may also have incentives and rebates that you can benefit from. In addition, you can save about $22,000 over 20 years on your utility bills, not including incentives.

Due to solar panels now being cheaper than ever as well as local and federal solar incentives, they are a worthwhile investment for most homeowners.

Environmental Impact of Switching to Solar in Thomaston

If you want to add solar panels to your home, one of the primary reasons why may be to reduce your greenhouse gas emissions. But how much can installing solar panels actually affect the environment? How much energy you use is an important factor to keep in mind. The more electricity your home uses, the greater your impact when you make the switch to solar power. Though solar panel manufacturing releases carbon dioxide emissions, the panels make up for it by greatly reducing the amount of CO2 you would have released if you still used nonrenewable energy. In Thomaston, you can reduce your carbon footprint by 40 pounds a year with solar panels. As you can see, using solar power has so many other rewards apart from saving money. One of the primary ones is that you can help save the Earth too.

Is it worth putting solar panels on my home?

What is the efficiency of solar panels?
