Methodology: How We Ranked the Best Solar Companies in Cahokia

EcoWatch's solar experts analyzed each solar company in Cahokia 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 Cahokia


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 Cahokia

For most homeowners, whether or not to invest in solar energy boils down to the cost. The cost of solar and the savings it generates vary depending on a few important factors such as:

  • Typical energy usage: The more energy your household uses on average and the larger your current energy bills are, the more money you could save by switching to solar.
  • Your home's orientation toward the sun: This, along with how your roof is set up, affects affect how much energy your solar panels can make.
  • Incentives: Tax-paying citizens who purchase and install a solar energy system this year can save 30% of their installation costs by using the federal solar investment tax credit. You can also save about $15,000 on your utility bills over 20 years without incentives.
  • Choice of solar panels: The type of solar panels you are interested in getting will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also lead to more savings over the lifetime of your system. If you don't need to maximize efficiency, you can opt for a higher number of more affordable panels.

There are lots of great benefits of solar in spite of the initial cost of installation. It can help the Earth and your wallet. In addition, it can increase the value of your home, leading to even more benefits if you decide to sell your home later.

EcoWatch's Cahokia, IL Solar Company Rankings FAQs

What is the top solar panel installation company in Cahokia?

In Cahokia, Mobius Solar is the best local solar company. Our team of experts rates it 5.00 stars, so it's a good choice if you're planning to add solar panels to your home.

What are some of the advantages and disadvantages of installing solar panels?

A few of the biggest pros are that it reduces your power bills, it's environmentally friendly, and it can give you a decent return on your investment (ROI). The most notable cons are that solar panels don't produce electricity at night, there is a high upfront cost and solar panels aren't always aesthetically pleasing.

Are solar panels worth it?

Solar panels require a large upfront investment that costs over ten thousand dollars, but whether or not solar panels are worth it depends on a range of factors like how much you pay for electricity and how much direct sunlight your roof gets.

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 less expensive 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.
