Methodology: How We Ranked the Best Solar Companies in Williamsville

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


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.

What is the top solar installer in Williamsville?

The top local solar company in Williamsville is Solar By CIR Buffalo, with a rating of 4.80 stars.

Are solar panels actually environmentally friendly?

Solar panels can be harmful for the environment when manufacturers use toxic chemicals in the construction. Chemicals can make solar panels difficult to recycle safely once they’ve reached the end of their lifespan. Solar panel manufacturing requires a lot of energy as well. The energy payback period is about 1 to 4 years.

Is it worth putting solar panels on my home?

Solar panels can be a fruitful investment for lots of homeowners, but frankly, they might not be worth it for everyone. If your home doesn't get enough sunlight or your energy bills are already pretty low, solar panels might not be for you.

How much solar panel capacity do I need for my house?

Solar panel capacity is rated based on how much power they generate under standard testing conditions. Since each panel can usually produce about 250 to 400 watts per hour, the average home will need 20 to 35 panels.
