Methodology: How We Ranked the Best Solar Companies in Gray

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


Below are some the criteria we examined specifically for Maine 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 Gray

The cost of installing a solar panel system has decreased significantly in the past several years, but it’s still a substantial investment for most homeowners.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:

  • System size and type: Some models are more costly than others, so the one you want to get can raise or lower your upfront cost. Plus, the more solar panels you need, the more it'll cost.
  • Your location: This affects how much sunlight your roof receives, which helps determine how many panels you need.
  • Incentives: Those who install a solar system this year can save 0 of their solar installation costs by using the federal solar investment tax credit. You can also save about $16,000 on your utility bills over 20 years not including incentives.
  • Energy consumption: Installing a solar system may be too pricey an option for families that don’t consume too much energy each month.

Though a solar panel system costs a decent chunk of money upfront, it can save you thousands of dollars over time. The question of how much, though, depends on a number of factors, including the amount of daily direct sunlight available and incentives.
