Methodology: How We Ranked the Best Solar Companies in Stony Brook University

EcoWatch's solar experts analyzed each solar company in Stony Brook University 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 Stony Brook University


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 Stony Brook University

For the majority of homeowners, whether or not to invest in solar panels depends the most on the cost.There are several factors you should take into consideration when trying to determine costs and your potential savings, such as:

  • Your city: This influences the average daily sunlight your roof gets, which helps determine how many panels you need.
  • Incentives: Something that can reduce the cost of 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 on your energy bills, which can generate an average of $22,000 of savings over 20 years.
  • Energy consumption: Installing a solar system may be an expensive option for homes that don’t need a good amount of energy a month.
  • System size and type: Some models are more pricy than others, so the one you get can raise or lower your upfront cost. Plus, the more solar panels you need to get, the more it'll cost.

Even though a solar panel system costs a sizable chunk of money upfront, it can save you a considerable amount over time. The question of how much, though, depends on several factors, such as the size of your solar panel system and your energy consumption.

Environmental Impact of Switching to Solar in Stony Brook University

An important reason so many are thinking of adopting solar energy is to help reduce their environmental impact.You may be wondering – how much do solar panels do for the environment anyway? In a city like Stony Brook University where energy use is somewhat high, installing solar panels is a fantastic idea for those who want to do their part for the environment.Because solar panels don’t release carbon dioxide emissions into the atmosphere when creating electricity, they’re a good swap for traditional energy sources. In fact, you could expect to reduce your carbon dioxide emissions by about 100 pounds each year. For those who are concerned about the environment, the upfront cost of solar is a small price to pay for offsetting your carbon emissions.
