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 New York 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, the decision of which solar installer to choose depends on pricing.The installation cost is just one important factor you should consider when looking into getting solar panels. How much it'll cost and how much you can save depend on things such as:

  • Choice of solar panels: The type 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 go with a higher number of more affordable panels.
  • The cost of energy for you: If your local energy rates are high, there's a good chance you'll have a higher return on your investment in solar panels. In Greenwich, you can save an average of $826 a month on your electricity bills.
  • Incentives: The federal solar investment tax credit currently allows you to reduce your taxes by 0 of the project cost. Your state and city may also have various incentives that you can use. In addition, you can save about $13,000 over 20 years on your utility bills, without incentives.
  • Energy consumption: Installing solar panels may be too pricey an investment for households that don’t use a good amount of energy each month.

Solar is a profitable investment for most homeowners. You can produce your own power instead of paying for it from a utility company and take advantage of solar tax credits and rebates, all while helping preserve the planet.

Environmental Impact of Switching to Solar in Greenwich

Switching to solar energy can have a positive impact on the environment.But you may be wondering – how much exactly can you help the planet by going solar? Something that can dramatically shape your carbon footprint is how long your commute is and how much you drive overall. If you go solar and drive an electric car, you can significantly lower your carbon dioxide emissions by charging your car at home.While solar panel production emits carbon dioxide, the panels make up for it by greatly lowering the amount of CO2 you would have been responsible for if you still used nonrenewable energy. In Greenwich, you can reduce your carbon footprint by 20 pounds a year with solar panels. As you can see, investing in solar has so many other rewards outside of saving money. One of the most important ones is that you can help save the environment too.
