Methodology: How We Ranked the Best Solar Companies in Newmarket

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


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 Newmarket

We get that for most homeowners, the choice to invest in solar rests on installation costs.There are quite a few factors you should consider when trying to figure out costs and your potential savings, including:

  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which gives you a tax credit currently worth 0 of your total installation cost, your local government may offer additional tax exemptions, credits or rebates that can help you save even more. Excluding incentives, you can save an average of $20,000 over 20 years with your solar system, too.
  • How much power your home consumes: Homes that use plenty of energy each month may need more solar panels and, as a result, more upfront cost, but will also enjoy more savings over time.
  • The type and model of solar panels you want: More efficient panels cost more, so that will affect your budget for your solar project.
  • Average daily sunlight: Since Newmarket gets a decent amount of average daily sunlight, your solar panels can generally generate enough energy to power your whole home, which influences how much you can save on your energy bills.

So are solar panels worth it? Whether you hope to reduce your electricity costs, carbon emissions or both, solar panels are a great investment for many Newmarket homeowners.
