Methodology: How We Ranked the Best Solar Companies in South Berwick

EcoWatch's solar experts analyzed each solar company in South Berwick 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 South Berwick


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 South Berwick

Even though solar panels can save you a good amount of money on power bills over time, it’s important to take into consideration the upfront costs.The cost and possible savings vary depending on some important factors such as:

  • Whether or not your roof gets a lot of direct sunlight: This, and your roof configuration, affects affect how much energy your solar panels can produce.
  • Incentives: Something that can reduce the cost of your solar project is the solar investment tax credit (ITC), which is a tax credit that’s equal to a percentage of the project cost. You can also save a decent amount of money on your utility bills, which can result in an average of $17,000 of savings over 20 years.
  • System size and type: Some models are more expensive than others, so the one you decide on can raise or lower your upfront cost. Plus, the more solar panels you need to get, the more it'll cost.
  • Energy consumption: Installing a solar system may be too steep of an investment for households that don’t need too much energy a month.

Even though a solar panel system costs a good chunk of money upfront, it can save you much more in the long term. The question of how much, though, depends on several factors, like the kind of solar panels you get and incentives.

What are the major pros and cons of going solar?

The advantages of solar power are that it can decrease or, in some cases, entirely eradicate your electricity bills, raise the value of your home and cut back on your carbon footprint.

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

The average payback period for solar panel installation is about 15.2 years, but the exact period is influenced by local electricity costs, incentives and net metering programs.
