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 Illinois 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 a solar energy system boils down to the cost. The overall price and potential savings vary depending on a few important factors such as:

  • Incentives: The federal solar investment tax credit, which everyone in the U.S. is eligible for, lets you deduct 30% of the cost of your solar system installation from your federal taxes. Additionally, not including incentives, you can save about $17,000 over 20 years on your energy bills.
  • The cost of energy for you: If your local energy rates are quite high, there's a good chance you'll get a higher return on your investment in solar panels. In Greenville, you can save an average of $93 a month on your electricity bills.
  • How much sunlight your roof gets: If your rooftop gets limited direct sunlight, your solar system won't be able to generate as much energy, which will give you lower savings on electricity bills than a house with a roof that gets a lot of sunlight.
  • How much power your home consumes: Households that need lots of electricity each month may need more solar panels and, as a result, be more expensive, but will also save more on their energy bills over time.

Due to the cost of solar panels being lower than before as well as local and federal solar incentives, they are a cost-effective investment for many homeowners.

Solar Incentives in Greenville

In order to increase solar panel installation and usage, incentives are offered by the government — and even some utility companies — to help make solar power more financially viable and accessible. You qualify for the federal solar investment tax credit (ITC) for the tax year you turn on your a solar system. You can also possibly pair the ITC with other local incentives. You can find out about the incentives you can use in our article on solar incentives

Environmental Impact of Switching to Solar in Greenville

Going solar can have a positive impact on the environment. Many homeowners might be wondering how much exactly they can impact the environment by switching to solar in Greenville, though. Adopting solar power is a sustainable choice for the environment, because the largest source of greenhouse gas emissions in the U.S. is from burning fossil fuels for electricity, heat, and transportation — all of which can be powered by solar instead. Although solar panel manufacturing releases carbon dioxide emissions, the panels make up for it by considerably decreasing the amount of CO2 you would have produced if you still used nonrenewable energy. In Greenville, you can reduce your carbon footprint by 100 pounds a year with solar panels. Since solar power is abundant and produces electricity without CO2 emissions, making the switch to solar power is one easy step you can take to help preserve the planet.
