Methodology: How We Ranked the Best Solar Companies in Gilmanton

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


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.

  • Incentives: Tax-paying citizens who install a solar energy system this year can save 0 of their total solar spend by using the federal solar investment tax credit. You can also save about $21,000 on your electricity bills over 20 years not including incentives.

Though a solar panel system costs a decent chunk of money upfront, it can save you thousands of dollars over time. The question of how much, though, depends on a number of factors, such as the size of your house and incentives.

EcoWatch's Gilmanton, NH Solar Company Rankings FAQs

Which solar panel installer is the best near me?

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

What are the best and worst things about solar power?

The greatest advantages of solar power are that it can lower or, for some, 100% eradicate your electricity bills, improve your home’s value and reduce your carbon footprint. The main 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 it doesn’t work for all roof types and locations.

Is it worth installing solar panels on my home?

Solar panels need a large upfront investment that usually costs at least ten thousand dollars, but whether or not solar panels are worth it depends on a variety of factors like how much you pay for electricity and how much direct sunlight your roof gets.

What are the different kinds of solar panels?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more expensive. Polycrystalline panels cost less but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other kinds can’t, like on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, roof configuration and how much efficiency you're looking for.
