Methodology: How We Ranked the Best Solar Companies in Greenlawn
EcoWatch's solar experts analyzed each solar company in Greenlawn 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 Greenlawn
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.

Many want to do their part to help protect the environment, which in many cases is the main reason for installing a solar system.But how much can installing solar panels actually affect the environment? According to the EPA, electricity generation is the second largest source of greenhouse gas emissions and about 62% of our electricity is produced by burning fossil fuels. Switching to a clean energy source like solar power can help reduce that number in a city like Greenlawn that generates a large amount of carbon dioxide emissions each year.Although making solar panels releases carbon dioxide emissions, the panels make up for it by significantly reducing the amount of CO2 you would have released if you still used nonrenewable energy. In Greenlawn, you can reduce your carbon footprint by 100 pounds a year with solar panels. As you can see, using solar power has so many other rewards outside of saving money. One of the major ones is that you can help save the Earth too.
