Methodology: How We Ranked the Best Solar Companies in Winchester

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


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 Winchester

Solar panels run off a free energy source — the sun — but to take advantage of this you must first pay to install your system. Some important things that influence the cost and possible savings include:

  • How much energy costs for you: The average household in Winchester spends around $1,100 a year on energy alone, so you could end up with that much in savings.
  • Incentives: Tax-paying citizens who install a solar energy system this year can save 30% of their 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.
  • Energy consumption: Installing solar panels may be too pricey an investment for households that don't use a good amount of energy per month.
  • Choice of solar panels: The kind of solar panels you buy will affect your total cost. High-efficiency monocrystalline panels are more expensive 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.

So is a solar system worth it? Whether you're trying to decrease your electric bills, carbon emissions or both, solar panels are a good investment for many Winchester homeowners.

EcoWatch's Winchester, CT Solar Company Rankings FAQs

Which solar installation company is the best near me?

In Winchester, Phoenix Energy is the most reputable local solar company. Our team of experts rates it 5.00 stars, so it's a great choice if you're looking to add solar panels to your roof.

What is the negative environmental impact of making solar panels?

Making solar panels uses chemicals and produces toxic waste that can be harmful for the environment, which is the main drawback of solar panels.

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

Solar panels generally pay for themselves in about 8.5 years, but your solar payback period will vary depending on your utility costs. The more your typical power bill, the faster your solar panel system will recoup your installation costs.

What is the best kind of solar panel?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more expensive. Polycrystalline panels are cheaper but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other kinds can't, like on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, the layout of your roof and how much energy generation you want.
