Methodology: How We Ranked the Best Solar Companies in South Portland
EcoWatch's solar experts analyzed each solar company in South Portland 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 Portland
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 Portland
When picking a solar company, most homeowners or business owners care about the costs above all. The cost and possible savings vary depending on some key factors such as:
- 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 on your energy bills, which can generate an average of $16,000 of savings over 20 years.
- The cost of energy for you: If your local power rates are high, there's a good chance you'll see a higher return on your investment in a solar panel system. In South Portland, you can save an average of $75 a month on your electricity bills.
- Typical energy usage: The more energy your household consumes on average and the steeper your current energy bills are, the more money you could save by making the switch to solar.
- 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 go with a higher number of more affordable panels.
Although a solar panel system costs a good chunk of money upfront, it can save you thousands of dollars over the lifespan of your panels. The question of how much, though, depends on several factors, including the amount of daily direct sunlight available and your energy consumption.

Solar Incentives in South Portland
One of the benefits of installing a solar panel system is earning federal and potentially state incentives. No matter what state you live in, you can take advantage of the federal Solar Investment Tax Credit (ITC), which will allow you to claim 30% of how much you paid for your solar installation when you file taxes, lowering the amount of taxes you owe that year. In addition, there may be some local incentives that can save you some extra money too. Our article on solar incentives has more information on the incentives you can find in South Portland.
Environmental Impact of Switching to Solar in South Portland
Lots of people want to do their part to help the planet, which for many is the main motivation to install solar panels. But how much can switching to solar actually help the environment? Regardless of your location, you can help the planet by switching to solar energy, but homes that use lots of energy will have an even bigger impact. Although solar panel production releases carbon dioxide emissions, the panels make up for it by considerably lowering the amount of CO2 you would have released if you still used nonrenewable energy. In South Portland, you can reduce your carbon footprint by 40 pounds a year with solar panels. As you can see, investing in solar has so many other perks outside of saving money. One of the main ones is that you can help save the planet too.
