Methodology: How We Ranked the Best Solar Companies in St. Clair

EcoWatch's solar experts analyzed each solar company in St. Clair 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 St. Clair


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 St. Clair

Solar panels run off a free energy source — the sun — but before you can take advantage of this you must first pay to set up your system.The installation cost is just one important factor you should bear in mind when looking into getting solar panels. How much it'll cost and how much you can save depend on things such as:

  • Incentives: The federal solar investment tax credit currently lets you reduce your taxes by 0 of the project cost. Your state may also have incentives and rebates that you can take advantage of. Additionally, you can save about $15,000 over 20 years on your utility bills, without incentives.
  • System size and type: Some models are more expensive than others, so the one you decide on can raise or lower your initial investment. Plus, the more solar panels you need to buy, the more it'll cost.
  • Where your home is: This affects how much sunlight your roof gets, which helps determine how many panels you need.
  • How much power your household needs: If your home regularly uses a lot of energy, you'll reap more rewards from going solar.

Thanks to solar panels now being cheaper than ever as well as various solar incentives, they are a cost-effective investment for most homeowners.

EcoWatch's St. Clair, IL Solar Company Rankings FAQs

What is the top solar installer in St. Clair?

The best local solar company in St. Clair is Pyramid Electrical Contractors, Inc., with a rating of 3.00 stars.

What is the negative environmental impact of solar panels?

Solar panels can be bad for the environment when manufacturers use toxic chemicals in the construction. Chemicals can make solar panels difficult to recycle safely once they’ve reached the end of their lifespan. Making solar panels uses a lot of energy as well. The energy payback period is about 1 to 4 years.

Is it worth putting solar panels on my roof?

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

When is the best time of year to install solar panels?

Although summer is the most common time people install solar panels, the perfect time is actually winter. You can save money since there's decreased demand during the winter months, and it allows you to be up and running with solar for the higher power bills you may get during the summer.

Our goal is to reach as many people as we can with sensible solutions like solar energy.
