Methodology: How We Ranked the Best Solar Companies in Winchester

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


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 Winchester

Solar panels run off a free energy source — the sun — but before you can take advantage of this you will first need to pay to install your panels.Some key things that affect the upfront cost and potential savings over time include:

  • The cost of energy for you: If your local power rates are quite high, there's a good chance you'll end up with a higher return on your investment in a solar system. In Winchester, you can save an average of $1,407 a month on your electricity bills.
  • Your income and budget: This determines what model of solar panels you can get.
  • Incentives: The federal solar investment tax credit, which everyone qualifies for, allows you to deduct 0 of the cost of your solar system installation from your federal taxes. Additionally, not including incentives, you can save about $19,000 over 20 years on your energy bills.
  • How much power your household consumes: Households that need plenty of energy each month may call for more solar panels and, consequently, be more expensive, but will also benefit more over time.

There are lots of great benefits of solar despite the upfront cost of installation. It can help the planet and your wallet. In addition, it can increase the value of your home, leading to even more benefits if you decide to sell your home later.

How long does it take to see a return on your investment after getting solar panels?

Solar panels typically pay for themselves in about 14.8 years, but your solar payback period will vary depending on your utility costs. The more your typical electricity bill, the faster your solar panel system will recoup your installation costs.
