Methodology: How We Ranked the Best Solar Companies in Hauppauge

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


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 Hauppauge, NY Solar Company Rankings FAQs

Which solar company is the best in Hauppauge?

The highest-rated local solar company in Hauppauge is SunPower, with a rating of 4.00 stars.

What are the pros and cons of switching to solar?

The main advantages of solar power are that it can decrease or, for some, completely cut your electricity bills, improve the value of your home and lower your carbon footprint. The 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 it doesn’t work for all roof types and locations.

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

Solar panels typically pay for themselves in about 11.1 years, but your solar payback period will vary based on your utility costs. The more your typical energy bill, the faster your solar panel system will recoup your installation costs.

What are the different types of solar panels?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more expensive. 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, like 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 how much efficiency you're looking for.
