Methodology: How We Ranked the Best Solar Companies in Thompsonville
EcoWatch's solar experts analyzed each solar company in Thompsonville 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 Thompsonville
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 Thompsonville
When picking a solar company, most homeowners or business owners worry about the costs above all. Some important factors that dictate the cost of installing a solar panel system on your home and how much it could save you over time include:
- Choice of solar panels: The kind of solar panels you buy will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also save you more money over the lifetime of your system. If space isn't a constraint for your project, you can opt for a higher number of more affordable panels.
- Your energy bills: This will affect how much money you might save. In Thompsonville, the average resident can save about $1,100 a year on their electricity bills.
- Incentives: Those who buy and install a solar system this year can save 30% of their solar installation costs by using the federal solar investment tax credit. You can also save about $22,000 on your electricity bills over 20 years not including incentives.
- How much sunlight your roof gets: If your roof doesn't see much direct sunlight, your solar panels won't be able to produce as much energy, which will give you lower savings on electricity bills than a house with a roof that gets lots of sunlight.
Solar is a fruitful investment for most homeowners. You can make your own electricity instead of paying for it from the grid and benefit from solar tax credits and rebates, all while helping the Earth.

You can learn about the incentives you can use in our article on solar incentives
Environmental Impact of Switching to Solar in Thompsonville
Many want to do their part for the planet, which often is the main reason they're interested in installing a solar system. But how much can switching to solar actually affect the environment? The more energy you use, the better off the planet will be if you switch to solar as you won't need to burn as many fossil fuels. Because solar panels don't release carbon dioxide emissions into the atmosphere when producing electricity, they're a good swap for traditional energy sources. In fact, you could reduce your carbon dioxide emissions by about 40 pounds each year. As you can see, using solar power has so many other perks outside of saving money. One of the most important ones is that you can help save the Earth too.
