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

When choosing a solar company, most homeowners or business owners care about the costs the most. Some important factors that influence the cost of installing a solar panel system on your home and how much it could save you over time include:

  • Energy consumption: Installing solar panels may be too steep of an option for families that don't consume too much energy a month.
  • The type and model of solar panels you want to get: Higher-efficiency panels have higher prices, so that will influence your budget for your solar project.
  • Your household's power bills: Based on the fairly high monthly electricity bills in Groton, you could save about $1,100 a year with solar.
  • Incentives: The federal solar investment tax credit, which everyone in the U.S. is eligible for, lets you deduct 30% of the cost of your solar system installation from your federal taxes. Plus, not including incentives, you can save about $23,000 over 20 years on your energy bills.

There are many great benefits of solar even with the initial cost of installation. It can help the environment and your finances. In addition, it can raise the value of your home, giving you even more benefits if you want to sell your home later.

Solar Incentives in Groton

Switching to solar power has plenty of considerable benefits. Not only can it help protect the planet, but you can also save a good amount of money on your installation with various government incentives. Regardless of where you live, you can take advantage of the federal Solar Investment Tax Credit (ITC), which lets you claim 30% of how much your solar project cost when you file taxes, lowering the amount of taxes you owe that year. Plus, there may be some state and city incentives you can benefit from too. For detailed information about incentives for homeowners in Groton, visit our article on solar incentives.

Environmental Impact of Switching to Solar in Groton

One of the reasons so many people consider installing solar panels is to help bring down their environmental impact. But how much can switching to solar actually help the environment? The more power your family uses, the the more the environment will benefit if you switch to solar since you won't need to use as much nonrenewable energy. Since solar panels don't release greenhouse gas emissions into the atmosphere when producing electricity, they're a good alternative to traditional energy sources. In fact, you could lower your carbon dioxide emissions by about 40 pounds each year. The perks of solar power are infinite — just like solar power is! That's why so many people have been happy with committing to solar.

How much solar panel capacity do I need for my house?
