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 Jersey 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

Solar panels are powered by a free energy source — the sun — but to take advantage of this you first need to pay to set up your system. The cost of solar and the savings it generates vary depending on a few important factors such as:

  • Incentives: The federal solar investment tax credit, which everyone qualifies for, allows you to deduct 30% of the cost of your solar system installation from your taxes. Additionally, not including incentives, you can save about $13,000 over 20 years on your energy bills.
  • How much energy costs for you: The average family in Greenwich shells out around $650 a year on energy alone, so you could gain that much in savings.
  • Choice of solar panels: The type of solar panels you get will affect your total cost. High-efficiency monocrystalline panels will cost more 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.
  • How much energy your household consumes: Homes that use plenty of power each month may require more solar panels and, therefore, more upfront cost, but will also enjoy more savings over time.

Thanks to the cost of solar panels being lower than before as well as several solar incentives, they are a worthwhile investment for many homeowners.

Solar Incentives in Greenwich

One of the benefits of installing a solar panel system is receiving government incentives. When you install a solar panel system, you can claim the federal tax credit, or ITC. This credit currently lowers your tax bill by 30% of the cost of your solar panels. Additionally, there may often be some regional incentives that you can take advantage of to further cut back on the cost of solar of solar panels. You can learn about the incentives you can take advantage of in our article on solar incentives

Environmental Impact of Switching to Solar in Greenwich

One of the most compelling reasons to embrace solar energy is to decrease your reliance on nonrenewable energy sources like burning fossil fuels, which are hazardous for the environment. A question many people might be asking themselves is how much can they really help save the environment by going solar anyway? The average person has a substantial carbon footprint. Between their car, which releases over 10,000 pounds of carbon dioxide emissions every year, and energy for their home, it can be overwhelming to figure out what to do. Going solar is a practical thing you can do to help. If you go solar, your carbon emissions can be cut by about 50 pounds each year. If you want to do your part for the environment, you'll likely recognize that there are many benefits of adopting solar energy other than just saving money on electricity. You can also help protect the environment, which some would argue is more valuable.

EcoWatch's Greenwich, NJ Solar Company Rankings FAQs

Which solar company is the best in Greenwich?

The top local solar company in Greenwich is Lumina Solar, with a rating of 4.23 stars.

What are the major advantages and disadvantages of switching to solar?

The biggest advantages of solar power are that it can lower or, for some, entirely erase your electricity bills, improve your home's value and reduce your carbon footprint. The biggest disadvantages are that solar panels can be expensive to install, you may not save as much if you don't use a lot of electricity and whether you can install solar panels depends on your roof configuration.

Are solar panels worth it?

Solar panels can be a great investment for most homeowners, but truthfully, they might not be worth it for everyone. If your home doesn't get enough sunlight or your electricity bills are already fairly low, solar panels might not be for you.

How efficient are solar panels?

Solar panel efficiency is the amount of solar energy that is converted into electricity. Most panels today have an efficiency rating between 15 and 20%. If your panels are more efficient, you'll need fewer of them to meet your home's energy needs.
