Methodology: How We Ranked the Best Solar Companies in Charlestown

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


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 Charlestown

Solar panels run off a free energy source — the sun — but before you can take advantage of this you must first pay to install your panels. The overall price and potential savings vary depending on some key factors such as:

  • average energy usage: The more energy your household uses on average and the greater your current energy bills are, the more likely you'll benefit from switching to solar.
  • System size and type: Some models are more expensive than others, so the one you want to get can raise or lower your initial investment. Plus, the more solar panels you need, the more it'll cost.
  • Incentives: Those who buy and install a solar system this year can save 30% of their total solar spend by using the federal solar investment tax credit. You can also save about $20,000 on your utility bills over 20 years without incentives.
  • Your current electric bills: Solar panels can significantly lower, or entirely eliminate, your utility bills. In Charlestown, you can save an average of $89 a month.

Because of the cost of solar panels being lower than before as well as various solar incentives, they are a worthwhile investment for many homeowners.

Solar Incentives in Charlestown

In order to increase solar panel installation and usage, federal and local governments — and even some utility companies — offer incentives to help make solar power more economically viable and accessible. When you install a solar panel system on your home, you become eligible to claim the federal tax credit, or ITC. This credit currently lets you lower your tax bill by 30% of the cost of your solar panels. Plus, there may often be some local incentives that you can use to further save. In our article on solar incentives, you can see the incentives you qualify for in Charlestown.

Environmental Impact of Switching to Solar in Charlestown

There are a few primary reasons why homeowners want to invest in solar energy: for the financial and environmental benefits. A question many might be thinking about is how much can they really help the environment by going solar anyway? One thing you should consider is your overall carbon footprint. For example, if you spend a lot of time on the road and have an electric vehicle, you can install solar panels on your home to power your EV and therefore help offset your carbon emissions. In Charlestown, the average homeowner can lower their carbon footprint by 40 pounds a year after going solar. As you can see, investing in solar has so many other perks outside of saving money. One of the major ones is that you can help save the Earth too.
