Methodology: How We Ranked the Best Solar Companies in Plymouth

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


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 Plymouth

Solar panels are powered by a free energy source — the sun — but to take advantage of this you will need to pay to set up your panels.There are a few factors you should consider when determining costs and your potential savings, such as:

  • Incentives: Those who purchase and install a solar system this year can save 0 of their total solar spend by taking advantage of the federal solar investment tax credit. You can also save about $20,000 on your energy bills over 20 years excluding incentives.
  • System size and type: Some models are more pricy than others, so the one you want can raise or lower your upfront cost. Plus, the more solar panels you need to get, the more it'll cost.
  • Typical energy usage: The more energy your home consumes on average and the higher your current power bills are, the more money you could save by making the switch to solar.
  • How much energy costs for you: The typical family in Plymouth pays around $1,500 a year on electricity alone, so you could end up with that much in savings.

Though a solar panel system costs a decent chunk of money upfront, it can save you thousands of dollars in the long term. The question of how much, though, depends on a number of factors, like the size of your solar panel system and incentives.

Solar Incentives in Plymouth

If you’re planning on making the switch to solar energy, a variety of government incentives and subsidies can dramatically lower the installation costs and expedite the return on your investment.On top of the federal tax credit incentive, there are also some state- and city-level benefits, which in most cases, stack with the federal incentive, so you can save even more. In our article on solar incentives, you can see the incentives you qualify for near you.

Environmental Impact of Switching to Solar in Plymouth

One of the most compelling reasons to embrace solar energy is to minimize your reliance on nonrenewable energy sources like burning fossil fuels, which are harmful for the environment.But how much can switching to solar actually help the environment? Something that can severely affect your carbon footprint is your commute time and how much you drive in general. If you install solar panels and drive an electric car, you can vastly lower your carbon dioxide emissions by charging your car at home.Because solar panels don’t release carbon dioxide emissions into the atmosphere when producing electricity, they’re a good trade for nonrenewable energy sources. In fact, you could expect to reduce your carbon dioxide emissions by about 40 pounds each year. The advantages of solar power are plentiful — just like solar power is! That's why so many homeowners have been happy with committing to solar.
