Methodology: How We Ranked the Best Solar Companies in Windham

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


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 Windham

When deciding on a solar company, most homeowners or business owners think about the costs the most.The cost of solar and the savings it generates vary depending on a few key factors such as:

  • The model of solar panel system you can afford: This hinges on how much you’re willing to invest upfront.
  • Incentives: Something that can make your solar project cost less 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 money on your energy bills, which can lead to an average of $16,000 of savings over 20 years.
  • The amount of sunlight your home gets: Because of Windham’s high amount of average daily sunlight, you should be able to save a decent amount on your energy bills.
  • How much energy your home consumes: Households that need lots of energy each month may require more solar panels and, as a result, be more expensive, but will also save more on their energy bills over time.

Solar is a profitable investment for most homeowners. You can generate your own electricity instead of paying for it from the grid and benefit from solar incentives and rebates, all while helping preserve the environment.

Environmental Impact of Switching to Solar in Windham

If you’re thinking of adding solar panels to your home, one of the primary reasons why may be to lower your carbon footprint.But you may be wondering – how much exactly can you help by going solar? Going solar is an impactful choice for the environment, because the largest source of greenhouse gas emissions in the country is from burning fossil fuels for electricity, heat, and transportation – all of which can be powered by solar instead.Though making solar panels releases carbon dioxide emissions, the panels make up for it by considerably reducing the amount of CO2 you would have been responsible for if you still used nonrenewable energy. In Windham, you can reduce your carbon footprint by 40 pounds a year with solar panels. As you can see, using solar power has so many other rewards apart from saving money. One of the primary ones is that you can help save the planet too.

What is the negative environmental impact of solar panels?

How long does it take for solar to pay for itself?

Solar panels typically pay for themselves in about 15.4 years, but your solar payback period will vary depending on your utility costs. The higher your typical power bill, the faster your solar panel system will pay for itself.

What is solar panel capacity and how much do I need for my house?
