Methodology: How We Ranked the Best Solar Companies in Sanford
EcoWatch's solar experts analyzed each solar company in Sanford 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 Sanford
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 Sanford
The cost of putting up a solar panel system has gone down significantly in the past few years, but it's still a large investment for most homeowners. Some important things that determine the upfront cost and potential savings over time include:
- How much electricity your household consumes: Homes that consume a lot of power each month may need more solar panels and, therefore, be more expensive, but will also save more on their energy bills over time.
- Incentives: Along with the federal Solar Investment Tax Credit (ITC), which gives you a tax credit currently worth 30% of your overall installation cost, your state or local government may offer additional tax exemptions, credits or rebates that will help you save even more. Excluding incentives, you can save an average of $17,000 over 20 years with your solar panels, too.
- How much energy costs for you: The typical family in Sanford spends around $920 a year on energy alone, so you could gain that much in savings.
- The model of solar panel system you can afford: This depends on your income and budget.
Solar is a rewarding investment for most homeowners. You can generate your own energy instead of paying for it from a utility company and benefit from solar tax credits and rebates, all while helping protect the Earth.

Environmental Impact of Switching to Solar in Sanford
Installing solar panels is a great way to do your part for a more eco-friendly future. But how much can using solar energy instead of traditional energy actually affect the environment? Using green energy for electricity rather than using nonrenewable energy is an impactful way to reduce carbon dioxide emissions if you're conscious of Sanford's fair level of greenhouse gas emissions. In fact, if you adopt solar power, you could reduce your carbon dioxide emissions by about 40 pounds each year. For those who are worried about the environment, the upfront cost of solar is a small price to pay for the offset carbon emissions.
