Methodology: How We Ranked the Best Solar Companies in Cambridge

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


Below are some the criteria we examined specifically for Vermont 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 Cambridge

The cost of installing solar panels has dropped greatly in the past several years, but it’s still a substantial investment for most homeowners.Some important things that determine how much it will cost and how much you could save include:

  • How much you spend on energy: The average household in Cambridge spends around $1,300 a year on electricity alone, so you could end up with that much in savings.
  • Incentives: The federal solar investment tax credit, which everyone qualifies for, allows you to deduct 0 of the cost of installing your solar panel system from your taxes. In addition, not including incentives, you can save about $24,000 over 20 years on your energy bills.
  • How much electricity your home consumes: Households that need lots of energy each month may call for more solar panels and, as a result, more upfront cost, but will also benefit more over time.
  • Average daily sunlight: Since Cambridge doesn’t get a lot of average daily sunlight, your solar system may not be able to generate enough energy to power your whole home, which influences how much you can save on your energy bills.

Even though a solar panel system costs a sizable chunk of money upfront, it can save you a considerable amount over time. The question of how much, though, depends on a number of factors, such as the size of your solar panel system and your local electricity rates.
