Benefits of Solar Energy

Solar energy provides several advantages that will enhance your home for years to come.

  • Reduced carbon footprint: Adopting solar is a surefire way to reduce your carbon footprint and home fossil fuel dependency.
  • Better energy independence: Solar panel systems can keep your home running through emergencies and blackouts, giving you additional security. You can use your solar energy anytime with an optional battery backup system.

How To Choose the Best Solar Company in St. Charles

The more comprehensive your company research is, the better your solar panels will ultimately function. Here are some essential aspects to bear in mind while searching for a solar provider.

Licensing and Training

In Illinois, the state Commerce Commission regulates distributed generation energy contractors, including solar contractors. You should also visit a company's website to learn about its private credentials. Two of the most recognized are the Solar Heating Installer and PV Installation Professional certificates, backed by the North American Board of Certified Energy Practitioners (NABCEP). Some companies don't publish this information online, so you should also ask your estimator about them.

Cost of Solar Panels in St. Charles

Your solar modules' style will impact how much energy you can produce. Monocrystalline panels are among the highest quality and perform the best but cost the most. Polycrystalline panels offer you a budget panel with a traditional design, but at the cost of less power generation. Thin-film panels are excellent for non-traditional roof shapes and cost the least, but don't work well for large residential installations.

You can also add battery backups and electric vehicle (EV) chargers. These will increase your total installation cost, but they can enhance your solar system's performance. Not every solar contractor includes these extras, so look for a contractor that installs them if it's important for you.

Generally speaking, it costs about $18,800 for a five-kilowatt solar array in St. Charles. This table displays more specific prices for different solar panel types and system components in your area.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,154
Solar Polycrystalline$900
Thin-Film$526
Solar Battery$739
Solar Home EV Charger$2,769

Financing Solar Energy in St. Charles

There are a plethora of ways to pay for a new solar system, and the right one will lower your costs. A few of the most common options include cash payments, power purchase agreements (PPAs), leases, and loans. Though it involves a large up-front payment, cash is the most affordable choice because it qualifies you for solar incentives and doesn't accrue interest. Solar loans are the next best option. As with a car loan or mortgage, you'll pay a monthly rate towards system ownership, including interest. You can still apply for cost-saving solar incentives, and depending on your lender, you could put as little as $0 down. Solar leases involve paying a set monthly rate to use rooftop panels. A PPA (Power Purchase Agreement) allows you to pay a monthly rate determined by the energy you use, similar to an electric bill. We generally don’t recommend these two options because you won't own the system and are disqualified from using solar incentives. Ask each provider you're vetting about the financing options it offers. A staff member can help you determine the optimal option for your pocketbook.

The table below lists the average payback periods for different capacities of solar systems in St. Charles.

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

Solar System CapacityEstimated Payback period
1 kW2.8 years
2 kW5.5 years
5 kW13.8 years
10 kW27.6 years
