Methodology: How We Ranked the Best Solar Companies in East Lyme

EcoWatch's solar experts analyzed each solar company in East Lyme 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 East Lyme


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 East Lyme

For many people, the decision of which solar company to hire depends on pricing.Some important factors that determine the cost of installing a solar panel system on your home and how much money you could save over time are:

  • Choice of solar panels: The kind of solar panels you need will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also lead to more savings 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.
  • Incentives: Those who install a solar energy system this year can save 0 of their overall solar costs by using the federal solar investment tax credit. You can also save about $23,000 on your energy bills over 20 years not including incentives.
  • Your current power bills: Solar panels can greatly reduce, or totally eradicate, your utility bills. In East Lyme, you can save an average of $1,844 a month.
  • How much sunlight your roof gets: If your roof doesn’t see much direct sunlight, your solar panel system won’t be able to generate as much energy, which will give you lower savings on energy bills than a house with a roof that gets a lot of sunlight.

Because of solar panels now being cheaper than ever as well as local and federal solar incentives, they are a cost-effective investment for most homeowners.

EcoWatch's East Lyme, CT Solar Company Rankings FAQs

What is the most reputable solar installation company in East Lyme?

The highest-rated local solar company in East Lyme is Ion Solar Pros, with a rating of 4.90 stars.

Are solar panels really environmentally friendly?

Solar panels can be detrimental for the environment when manufacturers use toxic chemicals in the manufacturing process. Chemicals can make solar panels difficult to recycle safely once they’ve reached the end of their lifespan. Solar panel manufacturing requires a lot of energy as well. The energy payback period is about 1 to 4 years.

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

Solar panels typically pay for themselves in about 10.8 years, but your solar payback period will vary depending on your utility costs. The more your typical power bill, the quicker your solar panel system will recoup your installation costs.

When is the best time of year to install solar panels?

You can put up solar panels whenever it's convenient for you, but consider doing so in the winter when there's less demand. With fewer homeowners switching to solar, you could potentially see faster installation times and more savings.

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