Methodology: How We Ranked the Best Solar Companies in Southampton

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


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 Southampton

The cost of putting up solar panels has dropped significantly over the past few years, but it’s still a large investment for most homeowners.There are quite a few factors you should take into consideration when trying to figure out how much it will cost and how much you can save, including:

  • Incentives: The federal solar investment tax credit, which everyone in the U.S. is eligible for, lets you deduct 0 of the cost of your solar system installation from your taxes. In addition, not including incentives, you can save about $22,000 over 20 years on your energy bills.
  • The model of solar panel system you can purchase: This is dependent on what your budget is.
  • Energy consumption: Installing a solar system may be a high-cost investment for homes that don’t consume too much energy a month.
  • Your household's power bills: With high monthly power bills in Southampton, you could save about $1,500 a year with solar.

Solar is a valuable investment for most homeowners. You can make your own electricity instead of paying for it from the grid and make use of solar incentives, all while helping preserve the planet.

Environmental Impact of Switching to Solar in Southampton

If you’re planning on adding solar panels to your home, one of the major reasons why may be to lower your reliance on nonrenewable energy.Something many homeowners might be wondering about is how much can they really help save the environment by switching to solar power anyway? In a city like Southampton where commute times can be pretty long, using solar power can help help reduce the carbon footprint of being on the road a lot.Because solar panels don’t release greenhouse gas emissions into the atmosphere when producing electricity, they’re a good swap for nonrenewable energy sources.

Since solar power is abundant and makes electricity without CO2 emissions, installing solar panels is one easy step you can take to help protect the environment.

EcoWatch's Southampton, NY Solar Company Rankings FAQs

What is the best solar installation company in Southampton?

The highest-rated local solar company in Southampton is Ion Solar Pros, with a rating of 4.90 stars.

What is the negative environmental impact of making solar panels?

Solar panels can be harmful for the environment when manufacturers use toxic chemicals in the construction. Chemicals can make solar panels difficult to dispose of safely once they’ve reached the end of their lifespan. Solar panel manufacturing needs a lot of energy as well. The energy payback period is about 1 to 4 years.

How long does it take to see a return on your investment after getting solar panels?

Solar panels typically pay for themselves in about 11.1 years, but your solar payback period will depend on your utility costs. The more your typical electricity bill, the faster your solar panel system will recoup your installation costs.

What is the best type of solar panel?

There are three main types of solar panels: monocrystalline, polycrystalline and thin-film. As for efficiency and price, monocrystalline has the highest for both, then polycrystalline, and then thin-film. The best choice for you is highly influenced by your roof configuration, how much you're willing to spend and how much energy generation you want.

Our goal is to reach as many people as we can with sensible solutions like solar energy.
