Methodology: How We Ranked the Best Solar Companies in Sullivan
EcoWatch's solar experts analyzed each solar company in Sullivan 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 Sullivan
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 Sullivan
The cost of installing solar panels has gone down greatly in the past several years, but it's still a substantial investment for most homeowners. Some key things that determine the upfront cost and potential savings over time include:
- Your income and budget: This affects what model of solar panels you can purchase.
- Where your home is: This influences the average daily sunlight your roof gets, which helps determine how many panels you need.
- Incentives: One thing 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 money on your energy bills, which can give you an average of $17,000 of savings over 20 years.
- Your power bills: This will influence your savings. In Sullivan, the average resident can save about $1,100 a year on their electricity bills.
Even though a solar panel system costs a sizable chunk of money upfront, it can save you much more in the long term. The question of how much, though, depends on a number of factors, such as the amount of daily direct sunlight available and your current power bills.

The more power your family uses, the the more the environment will benefit if you switch to solar as you won't have to rely on traditional energy sources as much. In fact, if you adopt solar power, you could look forward to lowering your carbon dioxide emissions by about 100 pounds each year. Since solar power is abundant and makes electricity without CO2 emissions, adding solar panels to your home is one easy step you can take to help protect the environment.
