Methodology: How We Ranked the Best Solar Companies in Milton

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


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 Milton

  • Electricity consumption: The average home in Milton doesn’t use much energy, and as a result may not see as many savings on their power bills.
  • Incentives: The federal solar investment tax credit currently allows you to decrease your taxes by 0 of the project cost. Your state may also have various incentives that you can use. In addition, you can save about $20,000 over 20 years on your utility bills, before factoring in incentives.
  • Where your home is: This affects how much sunlight your roof receives, which helps determine how many panels you need.

EcoWatch's Milton, NH Solar Company Rankings FAQs

Which solar company is the best near me?

The highest-rated local solar company in Milton is Mains Electric, LLC, with a rating of 3.00 stars.

What are the best and worst things about solar power?

A few of the biggest pros are that it reduces your power bills, it’s good for the environment, and it provides a significant return on your investment (ROI). The most notable cons are that solar panels don’t work as well when there’s limited direct sunlight, they cost a lot upfront and solar panels aren’t always aesthetically pleasing.

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

The average payback period for solar panel installation is about 14.0 years, but the exact period is influenced by local electricity costs, incentives and net metering programs.

What are the different types 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 types can’t, like on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, roof layout and desired energy output.
