Methodology: How We Ranked the Best Solar Companies in Williston Park

EcoWatch's solar experts analyzed each solar company in Williston Park 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 Williston Park


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 Williston Park

The cost of putting up solar panels has gone down significantly in the past several years, but it’s still a substantial investment for most homeowners.There are a few factors you should consider when trying to determine how much it will cost and how much you can save, such as:

  • Incentives: Those who purchase and install a solar system this year can save 0 of their total solar spend by using the federal solar investment tax credit. You can also save about $22,000 on your energy bills over 20 years without incentives.
  • How much sunlight your roof gets: If your rooftop doesn’t see much direct sunlight, your solar panel system won’t be able to generate as much energy, which will give you lower savings on electric bills than a roof that gets lots of sunlight.
  • average energy usage: The more energy your home consumes on average and the higher your current energy bills are, the more likely you'll benefit from going solar.
  • Choice of solar panels: The type of solar panels you are interested in getting 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.

Although a solar panel system costs a sizable chunk of money upfront, it can save you much more over time. The question of how much, though, depends on several factors, such as the size of your solar panel system and your energy consumption.

EcoWatch's Williston Park, NY Solar Company Rankings FAQs

Which solar installation company is the best in Williston Park?

In Williston Park, Kamtech Solar Solutions is the most reputable local solar company. Our team of experts rates it 4.80 stars, so it's a solid choice if you're looking to install solar panels on your roof.

What are the main pros and cons of adopting solar power?

The main advantages of solar power are that it can lower or, in some cases, 100% eradicate your electricity bills, improve the value of your home and lower your carbon footprint. The biggest disadvantages are that solar panels can be costly to install, you may not save a lot if you don’t use a lot of electricity and whether you can install solar panels depends on your roof configuration.

How long does it take to see a return on your investment after buying solar panels?

Solar panels typically pay for themselves in about 11.0 years, but your solar payback period will depend on your utility costs. The more your typical energy bill, the faster your solar panel system will recoup your installation costs.

How long do solar panels last?

Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely. What this means is how much energy they produce will have decreased by about 0.8% each year since installing them. You can decide to replace them once you've had them for that long or you can continue to use them at a lower efficiency after that time.

Our goal is to reach as many people as we can with sensible solutions like solar energy.
