Methodology: How We Ranked the Best Solar Companies in Smithtown

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


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 Smithtown

Solar panels are powered by a free energy source — the sun — but to take advantage of this you first need to pay to set up your system.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:

  • Average daily sunlight: Since Smithtown gets a decent amount of average daily sunlight, your solar panels can generally produce enough energy to power your whole home, which influences how much you can save on your energy bills.
  • The model of solar panels you’re thinking of getting: Higher-efficiency panels are more expensive, so that will affect your budget for your solar project.
  • Incentives: Something 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 on your power bills, which can give you an average of $22,000 of savings over 20 years.
  • Your energy bills: This will dictate how much you can save. In Smithtown, the average homeowner can save about $1,500 a year on their electricity bills.

There are lots of great benefits of solar in spite of the upfront cost of installation. It can help the planet and your wallet. In addition, it can raise the value of your home, resulting in even more benefits if you want to sell your home later.

Environmental Impact of Switching to Solar in Smithtown

Installing solar panels can have a meaningful impact on the environment.You may be curious – how much does going solar help the planet anyway? For those who care about the environment, switching to solar power is an easy decision, especially since Smithtown produces a very high amount of carbon dioxide emissions from its energy generation.Because solar panels don’t release CO2 emissions into the atmosphere when creating electricity, they’re a good alternative to nonrenewable energy sources. In fact, you could lower your carbon dioxide emissions by about 100 pounds each year. The great things about solar power are abundant — just like solar power is! That's why so many homeowners have been happy with committing to solar.

EcoWatch's Smithtown, NY Solar Company Rankings FAQs

Which solar installation company is the best near me?

The best local solar company in Smithtown is SunPower Corporation, with a rating of 4.00 stars.

What are the best and worst things about solar power?

The advantages of solar power are that it can reduce or, in some cases, totally eradicate your electricity bills, raise the value of your home and lower your carbon footprint. The main disadvantages are that solar panels can be expensive to install, you may not save a lot if you don’t use a lot of electricity and it doesn’t work for all roof types and locations.

Are solar panels worth it?

Solar panels can be a great investment for a majority of homeowners, but admittedly, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your energy bills are already fairly low, solar panels might not be for you.

How efficient are solar panels?

Solar panel efficiency is the amount of solar energy that is converted into electricity. Most panels today have an efficiency rating between 15 and 20%. If your panels are more efficient, you'll need fewer of them for your home's energy needs.
