Methodology: How We Ranked the Best Solar Companies in Portsmouth

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


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 Portsmouth

We know that for lots of homeowners, the decision to invest in solar highly depends on installation costs.The installation cost is just one important factor you should consider when looking into getting solar panels. How much it'll cost and how much you can save depend on things such as:

  • Where your home is: This influences the average daily sunlight your roof gets, which helps determine how many panels you need.
  • Incentives: The federal solar investment tax credit currently lets you reduce your taxes by 0 of the project cost. Your state and city may also have incentives and rebates that you can benefit from. In addition, you can save about $20,000 over 20 years on your utility bills, before factoring in incentives.
  • 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 to get, the more it'll cost.
  • How much power your home consumes: Homes that consume plenty of power each month may call for more solar panels and, therefore, more upfront cost, but will also enjoy more savings over time.

So is a solar panel system worth it? Whether you hope to lower your energy bills, greenhouse gas emissions or both, solar panels are a worthwhile investment for many Portsmouth homeowners.

Environmental Impact of Switching to Solar in Portsmouth

There are a few primary reasons why people are interested in solar energy: for the financial and environmental benefits.But how much can switching to solar actually help the environment? The average person has a substantial carbon footprint. Between their car, which produces over 10,000 pounds of carbon dioxide emissions each year, and electricity for their home, it can be overwhelming to figure out what to do. Installing solar panels is a practical thing you can do to help.Because solar panels don’t release carbon dioxide emissions into the atmosphere when creating electricity, they’re a good swap for nonrenewable energy sources. In fact, you could be looking at reducing your carbon dioxide emissions by about 40 pounds each year. The great things about solar power are abundant — just like solar power is! That's why so many homeowners have been happy with committing to solar.
