Methodology: How We Ranked the Best Solar Companies in Harwinton

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


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 Harwinton

Although solar panels can save you a good amount of money on utility bills over time, it’s necessary to take into consideration the startup costs.Some important factors that influence the cost of installing solar panels on your home and how much it could save you over time include:

  • How much power your home consumes: Homes that use plenty of power each month may call for more solar panels and, consequently, be more expensive, but will also save more on their energy bills over time.
  • The model of solar panel system you can purchase: This is dependent on how much you’re willing to invest upfront.
  • Incentives: The federal solar investment tax credit, which everyone qualifies for, lets you deduct 0 of the cost of installing your solar panel system from your taxes. In addition, not including incentives, you can save about $22,000 over 20 years on your energy bills.
  • The amount of sunlight your roof gets: If your rooftop doesn’t get a lot of direct sunlight, your solar panel system won’t be able to generate as much energy, which will give you lower savings on electricity bills than a roof that gets plenty of sunlight.

So are solar panels worth it? Whether you want to lower your electric bills, carbon emissions or both, solar panels are a good investment for many Harwinton homeowners.

Solar Incentives in Harwinton

Since solar power is more sustainable than fossil fuels, there are quite a few government incentives available to encourage people to make the switch.Regardless of what state you live in, you can take advantage of the federal Solar Investment Tax Credit (ITC), which will allow you to claim 0 of how much you paid for your solar installation on your tax return, reducing the amount of taxes you owe that year. Additionally, there may be some state and city incentives that can save you some extra money too. For more information about local incentives, check out our article on solar incentives.

Environmental Impact of Switching to Solar in Harwinton

Making the switch to solar power is a good way to do what you can for a more eco-friendly future.But you may be curious – how much exactly can you help the environment by making the switch to solar? Adopting solar power is an impactful choice for the environment, because the biggest source of greenhouse gas emissions in the country is from burning fossil fuels for electricity, heat, and transportation – all of which can be powered by solar instead.Since solar panels don’t release CO2 emissions into the atmosphere when creating 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, going solar has so many other rewards outside of saving money. One of the most important ones is that you can help save the planet too.
