Methodology: How We Ranked the Best Solar Companies in Stonington

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


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 Stonington

We know that for most homeowners, the choice to invest in solar comes down to installation costs. The overall price and potential savings vary depending on a few key factors such as:

  • Incentives: Something 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 utility bills, which can lead to an average of $23,000 of savings over 20 years.
  • Your income and budget: This shapes what type of solar panels you can buy.
  • How much energy costs for you: If your local electricity rates are quite high, there's a good chance you'll see a higher return on your investment in a solar system. In Stonington, you can save an average of $90 a month on your electricity bills.
  • Typical energy usage: The more electricity your household consumes on average and the steeper your current electricity bills are, the more likely you'll benefit from switching to solar.

Although a solar panel system costs a sizable chunk of money upfront, it can save you thousands of dollars in the long term. The question of how much, though, depends on a number of factors, like the angle of your roof and your current power bills.

Solar Incentives in Stonington

Since solar power is better for the environment than traditional energy sources, there are some government incentives available to encourage people to make the switch. State and city solar incentive programs depend on the location and, sometimes, utility company. A lot of states offer rebates for solar panels, in addition to the federal solar tax credit. Our article on solar incentives has more information on the incentives you can benefit from in Stonington.

Environmental Impact of Switching to Solar in Stonington

If you want to add solar panels to your home, one of the main reasons why may be to reduce your carbon footprint. But how much can switching to solar actually affect the environment? The amount of energy you use is an important factor to think about. The more energy your home uses, the greater your impact when you switch to solar energy. In Stonington, the average person can lower their carbon footprint by 40 pounds a year once they go solar. As you can see, trading traditional energy for solar has so many other rewards beyond saving money. One of the most important ones is that you can help save the Earth too.

Which solar company is the best near me?

The top local solar company in Stonington is Prime Energy Solar, with a rating of 5.00 stars.

What are the pros and cons of adopting solar power?

The greatest advantages of solar power are that it can lower or, for some, completely cut your electricity bills, raise the value of your home and lower your carbon footprint. The greatest disadvantages are that solar panels can be expensive to install, you may not see as many savings if you don't use a lot of electricity and whether you can install solar panels depends on your roof configuration.

How long does it take to see a return on your investment after buying solar panels?

Solar panels usually pay for themselves in about 8.2 years, but your solar payback period will vary depending on your utility costs. The more your typical energy bill, the faster your solar panel system will recoup your installation costs.

What is solar panel capacity and how much do I need for my house?

Solar panel capacity is how much energy the panels can produce under ideal conditions (a sunny day around noon). The average household has to get between 20 and 35 panels to account for how much energy they need.

Our goal is to reach as many people as we can with sensible solutions like solar energy.
