Methodology: How We Ranked the Best Solar Companies in Granite City
EcoWatch's solar experts analyzed each solar company in Granite City 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 Granite City
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 Granite City
Solar panels run off a free energy source — the sun — but to take advantage of this you first need to pay to install your system.Some key things that impact the cost and possible savings include:
- Your location: This affects how much sunlight your roof gets, which helps determine how many panels you need.
- Choice of solar panels: The type of solar panels you need 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 space isn't a constraint for your project, you can opt for a higher number of more affordable panels.
- How much energy you use: If your home uses a lot of energy, you'll reap more rewards from switching to solar.
- Your current electricity bills: Solar panels can greatly decrease, or totally eradicate, your utility bills. In Granite City, you can save an average of $851 a month.
Solar is a valuable investment for most homeowners. You can produce your own power instead of paying for it from a utility company and take advantage of solar incentives and rebates, all while helping protect the environment.

The energy payback period is about 1 to 4 years.
How long does it take to see a return on your investment after getting solar panels?
The average payback period for solar panel installation is about 20.3 years, but the exact period varies depending on local electricity costs, incentives and net metering programs.
When should I install solar panels?
Despite summer being the most popular time people install solar panels, the ideal 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.
