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

For many people considering switching to solar, the decision of which solar installer to choose comes down to pricing. There are quite a few factors you should take into consideration when trying to figure out costs and your potential savings, such as:

  • How much sunlight your roof gets: If your rooftop gets limited direct sunlight, your solar panels won't be able to generate as much energy, which will leave you with lower savings on power bills than a roof that gets a lot of sunlight.
  • The type and model of solar panels you want to get: More efficient models are more expensive, so that will affect your budget for your solar project.
  • Incentives: The federal solar investment tax credit currently lets you decrease your taxes by 30% of the project cost. Your state and even local utility companies may also have incentives and rebates that you can take advantage of. Additionally, you can save about $12,000 over 20 years on your utility bills, before factoring in incentives.
  • Electricity consumption: The average home in Granite City uses a decent amount of, and consequently may save on their energy bills.

There are many wonderful benefits of solar in spite of the upfront cost of installation. It can help the Earth and your bank account. In addition, it can raise the value of your home, giving you even more benefits if you choose to sell your home later.

Solar Incentives in Granite City

Although solar power is typically a $15,000 to $25,000 investment, it can save you a considerable amount of money over the lifespan of your solar panels due to smaller energy bills and government incentives. No matter what state you live in, you can take advantage of the federal Solar Investment Tax Credit (ITC), which lets you claim 30% of how much your solar project cost on your tax return, lowering the amount of taxes you owe that year. Plus, there may be some state and city incentives that can save you some extra money too.

Environmental Impact of Switching to Solar in Granite City

Many want to do their part to help save the planet, which in many cases is the chief reason for installing solar panels. But how much can using solar energy instead of traditional energy actually affect the environment? In a city like Granite City where energy use is rather high, switching to solar energy is a good plan for people who want to do their part for the environment. In fact, if you make the switch to solar power, you could lower your carbon dioxide emissions by about 100 pounds each year. If you want to do what you can for the environment, you'll no doubt recognize that there are many advantages to adopting solar energy other than just saving money on bills. You can also help preserve the environment, which some would argue is worth more.

EcoWatch's Granite City, IL Solar Company Rankings FAQs

What is the top solar panel company in Granite City?

The best local solar company in Granite City is Mobius Solar, with a rating of 5.00 stars.

What are a few of the advantages and disadvantages of going solar?

The greatest advantages of solar power are that it can lower or, for some, entirely cut your electricity bills, improve the value of your home and bring down your carbon footprint. The greatest disadvantages are that solar panels can be costly to install, you may not see as many savings if you don't use a lot of electricity and whether you can install solar panels depends on your roof configuration.

Are solar panels worth it?

Solar panels can be a great investment for many homeowners, but frankly, they might not be worth it for everyone. If your home doesn't get enough sunlight or your electricity bills are already fairly low, solar panels might not be for you.

What are the different kinds of solar panels?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also cost more. Polycrystalline panels cost less but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other kinds can't, like on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, roof layout and how much efficiency you're looking for.
