Methodology: How We Ranked the Best Solar Companies in South Farmingdale

EcoWatch's solar experts analyzed each solar company in South Farmingdale 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 South Farmingdale


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.

EcoWatch's South Farmingdale, NY Solar Company Rankings FAQs

What is the top solar company in South Farmingdale?

In South Farmingdale, Marcor Solar is the most reputable local solar company. Our team of experts rates it 5.00 stars, so it's a solid choice if you're looking to add solar panels to your house.

What are the pros and cons of solar power?

The main advantages of solar power are that it can decrease or, in some cases, entirely cut your electricity bills, improve the value of your home and bring down your carbon footprint. The greatest disadvantages are that solar panels can be pricey to install, you may not see as many savings if you don’t use a lot of electricity and it doesn’t work for all roof types and locations.

Is it worth installing solar panels on my roof?

Solar panels can be a good investment for most homeowners, but admittedly, 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.

What is the best kind of solar panel?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more costly. Polycrystalline panels are less expensive but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other kinds can’t, such as on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, the layout of your roof and desired energy output.

Our goal is to reach as many people as we can with sensible solutions like solar energy. Our team of full-time local researchers collects solar price and installation data for every city in America then compiles it to create these digestible city guides.
