Methodology: How We Ranked the Best Solar Companies in Port Jefferson

EcoWatch's solar experts analyzed each solar company in Port Jefferson 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 Port Jefferson


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 Port Jefferson

Although solar panels can save you a decent chunk of change on electricity bills over time, it’s important to take into consideration 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:

  • Choice of solar panels: The kind of solar panels you get 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.
  • Electricity consumption: The average household in Port Jefferson doesn’t use much energy, and therefore may not see as many savings on their power bills.
  • How much sunlight your roof gets: This, along with your roof configuration, affects affect how much energy your solar panels can produce.
  • Your power bills: This will determine how much you can save. In Port Jefferson, the average homeowner can save about $1,500 a year on their electricity bills.

Though a solar panel system costs a good chunk of money upfront, it can save you a considerable amount over time. The question of how much, though, depends on a number of factors, including the kind of solar panels you get and your current power bills.

Environmental Impact of Switching to Solar in Port Jefferson

One of the most compelling reasons to use solar power is to decrease your reliance on nonrenewable energy sources like burning fossil fuels, which are hazardous for the environment.You may be trying to figure out – how much does making the switch do for the environment anyway? One thing you should consider is your overall carbon footprint. For example, if you spend a lot of time on the road and have an electric vehicle, you can install solar panels on your home to power your EV and therefore help offset your carbon emissions.While making solar panels emits carbon dioxide, the panels make up for it by significantly lowering the amount of CO2 you would have been responsible for if you still used nonrenewable energy. In Port Jefferson, you can reduce your carbon footprint by 100 pounds a year with solar panels. The good things about solar power are abundant — just like solar power is! That's why so many Port Jefferson residents have been happy with committing to solar.
