Methodology: How We Ranked the Best Solar Companies in Watertown

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


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 Watertown

We get that for most homeowners, the choice to invest in solar depends on installation costs.Some important things that impact how much it will cost and how much you could save include:

  • The model of solar panel system you can afford: This depends on how much you’re willing to invest upfront.
  • Incentives: One thing that can reduce the cost of your solar project is the solar investment tax credit (ITC), which is a tax credit that’s equal to a percentage of the project cost. You can also save a decent amount of money on your energy bills, which can lead to an average of $22,000 of savings over 20 years.
  • How much power your home consumes: Households that consume lots of energy each month may require more solar panels and, consequently, be more expensive, but will also save more on their energy bills over time.
  • Your energy bills: This will influence how much you can save. In Watertown, the average resident can save about $1,800 a year on their electricity bills.

So is buying solar panels worth it? Whether you hope to decrease your electric bills, carbon dioxide emissions or both, solar panels are a worthwhile investment for many Watertown homeowners.

Environmental Impact of Switching to Solar in Watertown

Replacing nonrenewable energy with solar power is a powerful way to do what you can for a more environmentally-friendly future.Many homeowners might be wondering how much exactly they can impact the environment by switching to solar in Watertown, though. Everyone can help the planet by switching to solar energy, but homes that consume lots of energy will have an even bigger impact.Though making solar panels releases carbon dioxide emissions, the panels make up for it by greatly lowering the amount of CO2 you would have released if you still used traditional energy. In Watertown, you can reduce your carbon footprint by 40 pounds a year with solar panels. If you want to do your part for the environment, you’ll most likely recognize that there are many benefits of adopting solar energy other than just saving money on bills.
