Methodology: How We Ranked the Best Solar Companies in Copiague

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


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 Copiague

Even though solar panels can help save you a good amount of money on utility bills over time, it’s important to consider the upfront costs.The installation cost is just one important factor you should consider when looking into getting solar panels. How much it'll cost and how much you can save depend on things including:

  • Your city: This influences the average daily sunlight your roof gets, which helps determine how many panels you need.
  • Choice of solar panels: The kind of solar panels you buy will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also save you more money over the lifetime of your system. If you don’t need to maximize efficiency, you can opt for a higher number of more affordable panels.
  • Electricity consumption: The average household in Copiague doesn’t use much energy, and so may not see as many savings on their power bills.
  • Incentives: Tax-paying citizens who buy and install a solar energy 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.

Solar is a fruitful investment for most homeowners. You can generate your own energy instead of paying for it from the grid and benefit from solar incentives and rebates, all while helping preserve the environment.
