Best 5 Solar Companies in St. Charles, IL

How To Choose the Best Solar Company in St. Charles

Choosing a company is the first step toward a well-oiled and cost-efficient solar array. Here are some essential aspects to consider while shopping for a solar installer.

Licensing and Training

In Illinois, the state Commerce Commission licenses distributed generation energy contractors, including solar contractors. Solar companies can also pursue accreditations from standards organizations and trade groups. The most recognized ones in the industry come from the NABCEP. Most company websites will prominently display earned credentials, but you should also ask your estimator for more information.

Cost of Solar Panels in St. Charles

Different solar panel types look and perform differently. Monocrystalline panels offer the best energy production but cost more than other options and generally have the highest quality. Polycrystalline panels produce less power, but start at a more budget-friendly price point. Thin-film panels work well for small projects like RVs and sheds, but they're not ideal for larger installations due to their low performance.

Additional system add-ons, such as electric vehicle (EV) chargers and battery storage, will raise your overall installation costs. However, they might make your solar system more efficient and convenient to use. Not all solar companies offer these additional features, so look for a company that sells them if it's a priority for you.

Most St. Charles homeowners select solar systems designed for five kilowatts (kW) of electrical capacity. These systems run about $18,800 to set up, considering both materials and labor. You can see more specific solar cost information in the table.

Financing Solar Energy in St. Charles

Choosing the correct financing option will affect your overall solar system cost and expected savings. Common payment options include cash payments, loans, leases, and power purchase agreements. Most solar experts recommend a cash payment or using a solar loan. Cash payments require a large up-front sum, but they help you avoid paying interest, grant you system ownership, and qualify you for cost-saving solar incentives. Solar loans have the same benefits, though you'll pay more in total due to interest and fees. Much like a home or auto loan, you'll pay a set monthly rate with as little as $0 down. Solar leases allow you to pay a monthly fee to rent your panels, while a PPA lets you pay a fluctuating rate based on only the energy you use. We generally don't recommend these options since you won't own your system and are disqualified from solar incentives, but they might be appropriate in particular circumstances. Look for companies that offer several payment plans to find the right fit for your pocket.

You can claim a 26% federal solar tax credit from the IRS for new residential solar systems purchased before 2032. Additionally, local governments and utilities may have their own rebates and financing plans that could reduce your total cost even more.
