Methodology: How We Ranked the Best Solar Companies in Belmont

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


Below are some the criteria we examined specifically for New Hampshire 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 Belmont

When choosing a solar company, most homeowners or business owners worry about the costs above all.The cost of solar and the savings it generates vary depending on some important factors such as:

  • The type of solar panels you can buy: This depends on how much you’re willing to spend upfront.
  • Incentives: The federal solar investment tax credit, which everyone qualifies for, lets you deduct 0 of the cost of installing your solar panel system from your taxes. In addition, not including incentives, you can save about $21,000 over 20 years on your energy bills.
  • Electricity consumption: The average household in Belmont doesn’t use much energy, and consequently may not see as many savings on their power bills.
  • Where your home is: This affects the average daily sunlight your roof gets, which helps determine how many panels you need.

There are several great benefits of solar even with the upfront cost of installation. It can help the environment and your wallet. Additionally, it can increase the value of your home, leading to even more benefits if you decide to sell your home later.

EcoWatch's Belmont, NH Solar Company Rankings FAQs

What is the most reputable solar installer in Belmont?

The top local solar company in Belmont is Univix Power Solutions, with a rating of 3.00 stars.

What are a few of the major advantages and disadvantages of switching to solar?

The advantages of solar power are that it can reduce or, for some, 100% erase your electricity bills, raise the value of your home and bring down your carbon footprint. The disadvantages are that solar panels can be pricey to install, you may not see as many savings if you don’t use a lot of electricity and it doesn’t work for all roof types and locations.

How long does it take for solar to pay for itself?

Solar panels typically pay for themselves in about 13.6 years, but your solar payback period will depend on your utility costs. The more your typical energy bill, the quicker your solar panel system will recoup your installation costs.

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

Although summer is the most common time people install solar panels, the optimal time is actually winter. You can save money since there's less demand during the winter months, and it lets you be up and running with solar for the higher power bills you may get during the summer.

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