Solar energy comes with multiple advantages. Let's look at a few of them.

  • Better energy independence: Adding a battery backup or storage system lets you have trustworthy energy during storms and grid outages.
  • Lowered energy bills: You can skip the expensive cost of grid-tied power by producing some electricity right where you use it. Plus, many states provide net metering which can allow you to sell your unused energy back to help pay for your energy bill.
  • Reduced carbon footprint: Utilizing solar is a surefire way to reduce your carbon footprint and home fossil fuel dependency.

How To Choose the Best Solar Company in Wheaton

The cost and performance of solar panels often depend on the solar company that installed them. Make your choice based on the following key factors.

Licensing and Training

In Illinois, the state Commerce Commission licenses 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 respected are the Solar Heating Installer and PV Installation Professional certificates, granted 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 Wheaton

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 provide a lower price point but produce less power. 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.

You can also add battery backups and electric vehicle (EV) chargers. These will increase your total installation cost, but they can maximize your solar system's efficiency. Not every solar provider offers these optional components, so look for a provider that sells them if it's a priority for you.

You can plan to spend about $18,800 on average for a five-kilowatt solar energy system in Wheaton. Check the table in this section to get an idea of what amount Wheaton solar companies might quote for your specific solar system's price.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,190.71
Solar Polycrystalline$928.76
Thin-Film$542.97
Solar Battery$762.06
Solar Home EV Charger$2,857.71

Financing Solar Energy in Wheaton

Solar contractors use multiple different financing options to increase your savings and lower your costs. Though some providers offer unique payment plans, the most common are cash payments, solar leases, solar loans and power purchase agreements (PPAs). We suggest paying with cash or using a solar loan for the best return on investment (ROI). Cash payments require a hefty sum up-front, but you’ll pay the least long-term by avoiding interest. You’ll also own your system and can apply for solar panel incentives to minimize your total costs. Solar loans are another solid option if you don’t want to make a big initial investment. You can pay for your system in monthly installments while still enjoying energy bill savings and solar incentives. However, you’ll spend more in total due to accruing interest. Solar leases allow you to rent your panels for a set monthly rate, while PPAs let you pay only for the energy you use, akin to an electric bill. Both options disqualify you for solar incentives and do not provide you system ownership. Solar experts generally don't recommend them, but they might be suitable in some cases. Ask each company you're evaluating about the financing options it offers. A representative can help you determine the best option for your budget.

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

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 rebates and financing plans that could reduce your total cost even more.
