Methodology: How We Ranked the Best Solar Companies in Greenwich

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


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 Greenwich

For many people considering switching to solar, the decision of which solar company to hire comes down to costs.Some important factors that affect how much it will cost to install a solar panel system on your home and how much it could save you over time include:

  • System size and type: Some models are more expensive than others, so the one you want can raise or lower your initial investment. Plus, the more solar panels you need to buy, the more it'll cost.
  • Your household's power bills: Due to fairly high monthly electric bills in Greenwich, you could save about $1,900 a year with solar.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you receive a tax credit curretnly worth 0 of your overall installation cost, your state or local government may offer additional tax exemptions, credits or rebates that can help you save even more. Excluding incentives, you can save an average of $24,000 over the first 20 years with your solar system, too.
  • Your city: This affects how much sunlight your roof receives, which helps determine how many panels you need.

So is a solar system worth it? Whether you want to decrease your electricity costs, carbon emissions or both, solar panels are a great investment for many Greenwich homeowners.

What are a few of the major pros and cons of installing solar panels?

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

Solar panels typically pay for themselves in about 10.3 years, but your solar payback period will vary depending on your utility costs. The higher your typical electricity bill, the faster your solar panel system will recoup your installation costs.
