Methodology: How We Ranked the Best Solar Companies in Greenville
EcoWatch's solar experts analyzed each solar company in Greenville 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 Greenville
Below are some the criteria we examined specifically for Rhode Island 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 Greenville
For a lot of homeowners, whether or not to invest in solar panels boils down to the cost. A few key factors that determine how much it will cost to install a solar panel system on your home and how much money you could save over time are:
- Your current electric bills: Solar panels can greatly reduce, or completely get rid of, your utility bills. In Greenville, you can save an average of $73 a month.
- The model of solar panel system you can purchase: This is dependent on how much you're willing to invest upfront.
- Incentives: The federal solar investment tax credit currently allows you to decrease your taxes by 30% of the project cost. Your state and even local utility companies may also have various incentives that you can use. In addition, you can save about $20,000 over 20 years on your utility bills, before factoring in incentives.
- Energy consumption: Installing solar panels may be an expensive option for families that don't use a lot of energy per month.
Solar is a valuable investment for most homeowners. You can generate your own energy instead of paying for it from a utility company and take advantage of solar incentives, all while helping the Earth.

On top of the federal tax credit incentive, there are also some state- and city-level incentives, which in most cases, stack with the federal incentive, so you can save even more. In our article on solar incentives, you can see the incentives you qualify for in Greenville.
Environmental Impact of Switching to Solar in Greenville
There are a few main reasons why many people want to invest in solar energy: to put more money in their bank account and to help the planet. Many homeowners might be wondering how much exactly they can impact the environment by switching to solar in Greenville, though. One thing that can dramatically affect your carbon footprint is your commute time and how much you drive overall. If you install solar panels and drive an electric car, you can significantly lower your carbon dioxide emissions by charging your car at home. In Greenville, the average household can reduce their carbon footprint by 40 pounds a year after going solar. As you can see, trading traditional energy for solar has so many other rewards outside of saving money. One of the primary ones is that you can help save the planet too.

EcoWatch's Greenville, RI Solar Company Rankings FAQs
Which solar panel installer is the best near me?
The top local solar company in Greenville is New England Clean Energy, with a rating of 4.01 stars.
What are the pros and cons of solar power?
A few of the biggest pros are that it decreases your power bills, it's environmentally friendly, and it can give you a significant return on your investment (ROI). The most notable cons are that solar panels don't work as well when there's limited direct sunlight, the installation cost is pricey and solar panels can be an eyesore.
How long does it take to see a return on your investment after getting solar panels?
Solar panels generally pay for themselves in about 9.4 years, but your solar payback period will vary based on your utility costs. The higher your typical electricity bill, the faster your solar panel system will recoup your installation costs.
What are the different types of solar panels?
There are three main types of solar panels: monocrystalline, polycrystalline and thin-film. In terms of efficiency and price, monocrystalline has the highest for both, then polycrystalline, and then thin-film. The best choice for you is highly influenced by the layout of your roof, how much you're willing to spend and desired energy output.
