Methodology: How We Ranked the Best Solar Companies in Freeport
EcoWatch's solar experts analyzed each solar company in Freeport 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 Freeport
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 Freeport
The cost of putting up a solar panel system has gone down greatly over the past several years, but it’s still a large investment for most homeowners.There are a few factors you should take into consideration when trying to figure out costs and your potential savings, such as:
- Where your home is: This affects how much sunlight your roof receives, which helps determine how many panels you need.
- The type of solar panel system you can buy: This depends on how much you’re willing to invest upfront.
- Incentives: The federal solar investment tax credit, which everyone qualifies 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.
- How much energy your household consumes: Households that need a lot of power each month may call for more solar panels and, therefore, be more costly, but will also save more on their energy bills over time.
Solar is a valuable investment for most homeowners. You can produce your own power instead of paying for it from the grid and take advantage of solar incentives, all while helping protect the Earth.
