Methodology: How We Ranked the Best Solar Companies in Islip Terrace

EcoWatch's solar experts analyzed each solar company in Islip Terrace 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 Islip Terrace


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 Islip Terrace

For many readers, the decision of which solar company to hire depends on pricing. 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 such as:

  • System size and type: Some models are more costly than others, so the one you want can raise or lower your upfront cost. Plus, the more solar panels you need, the more it'll cost.
  • Your energy bills: This will determine how much you can save. In Islip Terrace, the average resident can save about $900 a year on their electricity bills.
  • Incentives: One thing that can save you money on your solar project is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save a decent amount of money on your energy bills, which can result in an average of $22,000 of savings over 20 years.
  • Your city: This influences the average daily sunlight your roof gets, which helps determine how many panels you need.

Although a solar panel system costs a decent chunk of money upfront, it can save you a considerable amount in the long term. The question of how much, though, depends on a number of factors, such as the kind of solar panels you get and your local electricity rates.

Solar Incentives in Islip Terrace

Since solar power is better for the environment than fossil fuels, there are various government incentives available to encourage its adoption. State and city solar incentive programs vary by location and, sometimes, utility company. Many states offer rebates for solar power systems, in addition to the federal solar tax credit. For more information about incentives that apply to you, see our article on solar incentives.

Environmental Impact of Switching to Solar in Islip Terrace

If you're considering adding solar panels to your home, one of the primary reasons why may be to reduce your reliance on nonrenewable energy. You may be trying to figure out — how much do solar panels help the environment anyway? Everyone can help save the environment by switching to solar energy, but homes that use lots of energy will have an even bigger impact. Since solar panels don't release CO2 emissions into the atmosphere when producing electricity, they're a good substitute for traditional energy sources. In fact, you could be looking at reducing your carbon dioxide emissions by about 100 pounds each year. As you can see, using solar power has so many other benefits apart from saving money. One of the main ones is that you can help save the environment too.
