Methodology: How We Ranked the Best Solar Companies in Lewiston

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


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 Lewiston

When choosing a solar company, most homeowners or business owners care about the costs above all.There are a few factors you should take into consideration when determining costs and your potential savings, such as:

  • Choice of solar panels: The type of solar panels you choose will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also lead to more savings over the lifetime of your system. If you don’t need to maximize efficiency, you can opt for a higher number of more affordable panels.
  • Incentives: The federal solar investment tax credit, which everyone in the U.S. is eligible for, lets you deduct 0 of the cost of installing your solar panel system from your taxes. In addition, not including incentives, you can save about $16,000 over 20 years on your energy bills.
  • average energy usage: The more electricity your home consumes on average and the larger your current energy bills are, the more likely you'll benefit from switching to solar.
  • The amount of sunlight your home gets: Due to Lewiston’s relatively low amount of average daily sunlight, you might not see as many savings on your power bills.

Thanks to solar panels now being cheaper than ever as well as several solar incentives, they are a solid investment for many homeowners.

Environmental Impact of Switching to Solar in Lewiston

There are tons of reasons to switch to solar energy, like saving money on utility bills and helping to lower your carbon footprint.But you may be curious – how much exactly can you help the environment by making the switch to solar? 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 use solar energy for your home to power your EV and therefore help offset your carbon emissions.Even though solar panel manufacturing emits carbon dioxide, the panels make up for it by significantly decreasing the amount of CO2 you would have been responsible for if you still used traditional energy. In Lewiston, you can reduce your carbon footprint by 40 pounds a year with solar panels. Since energy from the sun is abundant and makes electricity without a carbon footprint, installing solar panels is one easy step you can take to help protect the planet.
