Methodology: How We Ranked the Best Solar Companies in Willowbrook
EcoWatch's solar experts analyzed each solar company in Willowbrook 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 Willowbrook
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 Willowbrook
When deciding on a solar company, most homeowners or business owners worry about the costs above all. The cost and possible savings vary depending on some key factors such as:
- Your energy consumption: If your household needs to use a lot of energy, you'll reap more rewards from switching to solar.
- Your income and budget: This determines what model of solar panels you can purchase.
- How much sunlight your roof gets: If your roof doesn't see much direct sunlight, your solar panel system won't be able to make as much energy, which will leave you with lower savings on electric bills than someone with a roof that gets lots of sunlight.
- Incentives: Those who buy and install a solar system this year can save 30% of their solar installation costs by using the federal solar investment tax credit. You can also save about $13,000 on your utility bills over 20 years excluding incentives.
Though a solar panel system costs a good chunk of money upfront, it can save you a considerable amount over the lifespan of your panels. The question of how much, though, depends on several factors, including the kind of solar panels you get and your current power bills.

Environmental Impact of Switching to Solar in Willowbrook
There are a few main reasons why homeowners want to invest in solar energy: to put more money in their bank account and to help the planet. You may be asking yourself — how much do solar panels help the environment anyway? One thing that can drastically shape your carbon footprint is your commute time and how much you drive overall. If you go solar and drive an electric car, you can vastly lower your carbon dioxide emissions by charging your car at home. While solar panel manufacturing releases carbon dioxide emissions, the panels make up for it by significantly decreasing the amount of CO2 you would have produced if you still used nonrenewable energy. In Willowbrook, you can reduce your carbon footprint by 90 pounds a year with solar panels. As you can see, investing in solar has so many other benefits besides saving money. One of the primary ones is that you can help save the environment too.
