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 many people, the decision of which solar company to go with depends on total costs.The overall price and potential savings vary depending on some key factors such as:

  • Your income and budget: This guides what type of solar panels you can buy.
  • Incentives: One thing that can save you money on your solar project is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save money on your power bills, which can result in an average of $17,000 of savings over 20 years.
  • Your location: This affects how much sunlight your roof gets, which helps determine how many panels you need.
  • Typical energy usage: The more energy your home consumes on average and the higher your current electricity bills are, the more likely you'll benefit from switching to solar.

Solar is a worthwhile investment for most homeowners. You can generate your own energy instead of paying for it from a utility company and benefit from solar incentives and rebates, all while helping protect the planet.

EcoWatch's Greenville, IL Solar Company Rankings FAQs

Which solar panel installer is the best near me?

The best local solar company in Greenville is Route 66 Solar, with a rating of 4.90 stars.

What are a few of the main advantages and disadvantages of installing solar panels?

The main advantages of solar power are that it can decrease or, in some cases, totally eradicate your electricity bills, raise your home’s value and cut back on your carbon footprint. The disadvantages are that solar panels can be costly to install, you may not save as much if you don’t use a lot of electricity and whether you can install solar panels depends on your roof configuration.

Are solar panels worth it?

Solar panels can be a great investment for a majority of homeowners, but frankly, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your energy bills are already fairly low, solar panels might not be for you.

What is the best kind of solar panel?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also cost more. Polycrystalline panels are cheaper but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other kinds can’t, such as on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, the layout of your roof and desired energy output.
