Methodology: How We Ranked the Best Solar Companies in Waterbury

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


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 Waterbury

For most homeowners, the decision to invest in a solar energy system comes down to the cost. Some important things that impact the upfront cost and potential savings over time include:

  • Incentives: The federal solar investment tax credit, which can save you some money, allows you to deduct 30% of the cost of installing your solar panel system from your federal taxes. In addition, not including incentives, you can save about $23,000 over 20 years on your energy bills.
  • Your current electric bills: Solar panels can significantly reduce, or totally get rid of, your utility bills. In Waterbury, you can save an average of $90 a month.
  • average energy usage: The more electricity your home uses on average and the higher your current electricity bills are, the more likely you'll benefit from switching to solar.
  • Your income and budget: This shapes what type of solar panels you can buy.

Because of solar panels decreasing in cost as well as several solar incentives, they are a sound investment for many homeowners.

Solar Incentives in Waterbury

There are a lot of federal, state and local rebates and tax credits that may earn you some money in return after buying a qualifying system. For detailed information about incentives that apply to you, check out our article on solar incentives.

Environmental Impact of Switching to Solar in Waterbury

Going solar can have a positive impact on the environment. You may be curious — how much does going solar do for the planet anyway? One thing that can dramatically influence your carbon footprint is how long your commute is and how much you drive altogether. If you install solar panels and have an electric car, you can greatly reduce your carbon dioxide emissions by charging your car at home. Since solar panels don't release greenhouse gas emissions into the atmosphere when generating electricity, they're a good substitute for traditional energy sources. In fact, you could lower your carbon dioxide emissions by about 40 pounds each year. As you can see, investing in solar has so many other benefits beyond saving money. One of the most important ones is that you can help save the planet too.
