Methodology: How We Ranked the Best Solar Companies in Walpole

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


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 Walpole

For many people considering switching to solar, the decision of which solar installer to go with depends on pricing. The overall price and potential savings vary depending on some important factors such as:

  • Incentives: The federal solar investment tax credit currently lets you decrease your taxes by 30% of the project cost. Your state may also have various incentives that you can benefit from. Additionally, you can save about $19,000 over 20 years on your utility bills, before factoring in incentives.
  • System size and type: Some models are more costly than others, so the one you choose can raise or lower your upfront cost. Plus, the more solar panels you need to buy, the more it'll cost.
  • Energy consumption: Solar may be too steep of an option for households that don't use too much energy each month.
  • Your power bills: This will affect how much you can save. In Walpole, the average resident can save about $1,000 a year on their electricity bills.

So are solar panels worth it? Whether you hope to reduce your energy bills, carbon emissions or both, solar panels are a solid investment for many Walpole homeowners.

Environmental Impact of Switching to Solar in Walpole

Swapping traditional energy for solar is a great way to do your part for a more eco-friendly future. A question many homeowners might be asking themselves is how much can they really help protect 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 in the car 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 Walpole, the average person can lower their carbon footprint by 40 pounds a year after going solar. Since energy from the sun is abundant and makes electricity without a carbon footprint, making the switch to solar power is one easy step you can take to help preserve the environment.
