Methodology: How We Ranked the Best Solar Companies in Williston

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


Below are some the criteria we examined specifically for Vermont 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 Williston

For many people, the decision of which solar installer to hire comes down to pricing.Some significant things that determine the upfront cost and potential savings over time include:

  • Your income and budget: This guides what type of solar panels you can afford.
  • How much energy your home consumes: Homes that use plenty of energy each month may call for more solar panels and, as a result, be more costly, but will also enjoy more savings over time.
  • Incentives: The federal solar investment tax credit, which everyone in the U.S. is eligible for, lets you deduct 0 of the cost of installing your solar panel system from your federal taxes. Plus, not including incentives, you can save about $23,000 over 20 years on your energy bills.
  • How much you spend on energy: The typical household in Williston shells out around $1,400 a year on energy alone, so you could gain that much in savings.

Even though a solar panel system costs a decent chunk of money upfront, it can save you thousands of dollars over the lifespan of your panels. The question of how much, though, depends on several factors, like the size of your house and incentives.

Environmental Impact of Switching to Solar in Williston

Going solar can have a positive effect on the environment.Many homeowners might be wondering how much exactly they can impact the environment by switching to solar in Williston, though. One thing you should keep in mind is your overall carbon footprint. For example, if you spend lots of time commuting to work and have an electric vehicle, you can use solar energy for your home to power your EV and therefore help offset your carbon emissions.Although solar panel manufacturing emits carbon dioxide, the panels make up for it by significantly reducing the amount of CO2 you would have released if you still used nonrenewable energy. In Williston, you can reduce your carbon footprint by 40 pounds a year with solar panels. If you want to do your part for the environment, you’ll no doubt understand that there are many good things about adopting solar energy other than just saving money on bills. You can also help protect the environment, which some would argue is invaluable.

What are some of the major pros and cons of switching to solar?

The greatest disadvantages are that solar panels can be expensive to install, you may not save as much if you don’t use a lot of electricity and whether you can install solar panels depends on your roof configuration.

Are solar panels worth it?

Solar panels require a considerable upfront investment that usually costs at least ten thousand dollars, but whether or not solar panels are worth it depends on a collection of factors like the cost of electricity near you and how much direct sunlight your roof gets.

When is the best time of year to install solar panels?

You can install solar panels whenever it's convenient for you, but consider doing so in the winter when the demand is less. With fewer homeowners going solar, you could potentially see quicker installation times and more savings.
