Methodology: How We Ranked the Best Solar Companies in South Windsor

EcoWatch's solar experts analyzed each solar company in South Windsor 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 South Windsor


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 South Windsor

For many homeowners, the decision to invest in solar panels comes down to the cost.Some key factors that determine the cost of installing solar panels on your home and how much it could save you over time include:

  • The amount of sunlight your house gets: Thanks to South Windsor’s high amount of average daily sunlight, you should be able to save a decent amount on your energy bills.
  • How much energy costs for you: If your local power rates are quite high, there's a good chance you'll have a higher return on your investment in solar panels. In South Windsor, you can save an average of $1,844 a month on your electricity bills.
  • The type of solar panel system you can buy: This hinges on how much you’re willing to invest upfront.

Solar Incentives in South Windsor

There are many reasons why going solar is a great investment. One of them consists of some government incentives that can save you money.Everyone can take advantage of the federal Solar Investment Tax Credit (ITC), which allows you to claim 0 of how much you paid for your solar installation on your tax return, lowering the amount of taxes you owe that year. Plus, there may be some local incentives that stack with the ITC too. In our article on solar incentives, you can read about the incentives you qualify for in South Windsor.

Environmental Impact of Switching to Solar in South Windsor

Many want to do their part to help save the environment, which in many cases is the chief reason they’re interested in installing a solar system.Something many homeowners might have in mind is how much can they really help preserve the environment by going solar anyway? According to the EPA, electricity generation is the second largest source of greenhouse gas emissions and about 62% of our electricity comes from burning fossil fuels. Installing solar panels and switching to renewable energy can help bring down that number in a city like South Windsor that accounts for a fair amount of carbon dioxide emissions each year.Although solar panel manufacturing emits carbon dioxide, the panels make up for it by greatly reducing the amount of CO2 you would have released if you still used nonrenewable energy. In South Windsor, you can reduce your carbon footprint by 40 pounds a year with solar panels. The good things about solar power are infinite — just like solar power is! That's why so many people have been happy with making the switch to solar.
