Methodology: How We Ranked the Best Solar Companies in Groton

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


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 Groton

The cost of putting up solar panels has gone down immensely over the past several years, but it’s still a large investment for most homeowners.The installation cost is just one important factor you should take into account when looking into getting solar panels. How much it'll cost and how much you can save depend on things including:

  • How much sunlight your roof gets: If your rooftop doesn’t see much direct sunlight, your solar panels won’t be able to make as much energy, which will give you lower savings on energy bills than a roof that gets lots of sunlight.
  • System size and type: Some models are more expensive than others, so the one you get can raise or lower your upfront cost. Plus, the more solar panels you need, the more it'll cost.
  • Incentives: The federal solar investment tax credit, which everyone in the U.S. is eligible for, lets you deduct 0 of the cost of your solar system installation from your taxes. Additionally, not including incentives, you can save about $23,000 over 20 years on your energy bills.
  • Your household's power bills: Due to fairly high monthly electricity bills in Groton, you could save about $1,700 a year with solar.

Solar is a valuable investment for most homeowners. You can produce your own electricity instead of paying for it from the grid and make use of solar tax credits and rebates, all while helping the Earth.

Environmental Impact of Switching to Solar in Groton

EcoWatch's Groton, CT Solar Company Rankings FAQs

What is the top solar panel company in Groton?

The highest-rated local solar company in Groton is Sunrun Fusion New England, with a rating of 3.00 stars.

Are solar panels really environmentally friendly?

Solar panels can be detrimental for the environment when manufacturers use toxic chemicals in the manufacturing process. Chemicals can make solar panels difficult to dispose of safely once they’ve reached the end of their lifespan. Solar panel manufacturing uses a lot of energy as well. The energy payback period is about 1 to 4 years.

Are solar panels worth it?

Solar panels can be a great investment for a majority of homeowners, but truthfully, they might not be worth it for everyone. If your home doesn't get enough sunlight or your electricity bills are already pretty low, solar panels might not be for you.

How long do solar panels last?

On average, the lifespan of solar panels is about 25 to 30 years. Some even last up to 50 years, but efficiency decreases by about 0.8% each year. You can choose to replace them sooner if you want to maintain a higher amount of energy production.
