Methodology: How We Ranked the Best Solar Companies in Plymouth

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


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 Plymouth

For many homeowners, whether or not to invest in a solar energy system boils down to the cost. A few important factors that determine the cost of installing a solar panel system on your home and how much it could save you over time are:

  • How much sunlight your roof gets: If your rooftop gets limited direct sunlight, your solar system won't be able to generate as much energy, which will leave you with lower savings on power bills than someone with a roof that gets lots of sunlight.
  • Incentives: Those who purchase and install a solar system this year can save 30% of their installation costs by using the federal solar investment tax credit. You can also save about $22,000 on your utility bills over 20 years excluding incentives.
  • The model of solar panels you can afford: This hinges on how much you're willing to spend upfront.
  • Your energy bills: This will influence how much you can save. In Plymouth, the average homeowner can save about $1,100 a year on their electricity bills.

Although a solar panel system costs a sizable chunk of money upfront, it can save you a considerable amount over the lifespan of your panels. The question of how much, though, depends on several factors, like the kind of solar panels you get and your energy consumption.

Solar Incentives in Plymouth

Since solar power is a cleaner source of energy than fossil fuels, there are a number of government incentives in place to encourage its adoption. These incentives normally consist of cash rebates, tax breaks and/or performance-based incentives. They can cut the cost of going solar by 30%, upwards of 50% in some cases. For more information about incentives that apply to you, see our article on solar incentives.

Environmental Impact of Switching to Solar in Plymouth

One of the reasons so many consider adopting solar energy is to help reduce their environmental impact. But you may be curious — how much exactly can you help by using solar power? The more power your household uses, the the more the environment will benefit if you switch to solar as you won't need to rely on traditional energy sources as much. When you go solar, your carbon emissions can be lowered by about 40 pounds every year. If you want to do your part for the environment, you'll no doubt understand that there are many benefits of adopting solar energy other than just saving money on bills. You can also help preserve the environment, which some would argue is worth more.
