Methodology: How We Ranked the Best Solar Companies in Belleville
EcoWatch's solar experts analyzed each solar company in Belleville 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 Belleville
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 Belleville
For most homeowners, whether or not to invest in a solar energy system depends the most on the cost. The cost and possible savings vary depending on some key factors such as:
- The amount of sunlight your roof gets: If your rooftop gets limited direct sunlight, your solar panels won't be able to produce as much energy, which will give you lower savings on electric bills than a roof that gets a lot of sunlight.
- How much electricity your household consumes: Households that need plenty of electricity each month may need more solar panels and, consequently, more upfront cost, but will also save more on their energy bills over time.
- The model of solar panels you're planning on getting: Higher-efficiency panels are more expensive, so that will affect your budget for your solar project.
- Incentives: The federal solar investment tax credit, which everyone qualifies for, allows you to deduct 30% of the cost of installing your solar panel system from your taxes. Additionally, not including incentives, you can save about $15,000 over 20 years on your energy bills.
Thanks to solar panels now being cheaper than ever as well as local and federal solar incentives, they are a worthwhile investment for many homeowners.

Solar Incentives in Belleville
Switching to solar power has plenty of great benefits. Not only can it help protect the environment, but you can also save some money on your installation with various government incentives. Local solar incentive programs depend on the location and, sometimes, utility company. Many states offer rebates for solar power, in addition to the federal solar tax credit. In our article on solar incentives, you can see the incentives you qualify for near you.
Environmental Impact of Switching to Solar in Belleville
Lots of people want to do what they can for the planet, which often is the chief motivation to install solar panels. But you may be curious — how much exactly can you help the planet by using solar power? As stated by the EPA, electricity production is the second biggest source of greenhouse gas emissions and about 62% of our electricity comes from burning fossil fuels. Using solar power can help put a dent in that number in a city like Belleville that accounts for a large amount of carbon dioxide emissions each year. In fact, if you adopt solar power, you could lower your carbon dioxide emissions by about 100 pounds each year. As you can see, going solar has so many other rewards outside of saving money. One of the main ones is that you can help save the environment too.

EcoWatch's Belleville, IL Solar Company Rankings FAQs
What is the most reputable solar company in Belleville?
In Belleville, PricingUtilities is the most reputable local solar company. Our team of experts rates it 3.00 stars, so it's a great choice if you're looking to add solar panels to your house.
Are solar panels actually good for the environment?
Solar panels can be harmful for the environment when manufacturers use toxic chemicals in the construction. Chemicals can make solar panels difficult to dispose of safely once they've reached the end of their lifespan. Making solar panels needs a lot of energy as well. The energy payback period is about 1 to 4 years.
How long does it take to see a return on your investment after installing solar panels?
Solar panels typically pay for themselves in about 12.0 years, but your solar payback period will vary based on your utility costs. The more your typical electricity bill, the quicker your solar panel system will pay for itself.
What are the different types of solar panels?
The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more expensive. 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 how much efficiency you're looking for.
