Methodology: How We Ranked the Best Solar Companies in East Islip
EcoWatch's solar experts analyzed each solar company in East Islip 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 East Islip
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 East Islip
The cost of installing a solar panel system has gone down greatly over the past several years, but it's still a large investment for most homeowners. Some important factors that affect how much it will cost to install solar panels on your home and how much money you could save over time are:
- Incentives: Along with the federal Solar Investment Tax Credit (ITC), which gives you a tax credit currently worth 30% of your overall installation cost, your state or local government may offer additional tax exemptions, credits or rebates that will help you save even more. Aside from incentives, you can save an average of $22,000 over the first 20 years with your system, too.
- Your power bills: This will impact how much money you might save. In East Islip, the average resident can save about $900 a year on their electricity bills.
- Choice of solar panels: The type of solar panels you want 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 go with a higher number of more affordable panels.
- The amount of sunlight your roof gets: This, along with how your roof is set up, affects affect how much energy your solar panels can produce.
Though a solar panel system costs a decent chunk of money upfront, it can save you much more over time. The question of how much, though, depends on a number of factors, including the angle of your roof and incentives.
