Benefits of Solar Energy

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

  • Reduced carbon footprint: Using clean solar power means you're less dependent on fossil fuels, which emit harmful greenhouse gasses.
  • Better energy independence: Adding a battery storage system lets you have reliable energy during grid outages and storms.
  • Lowered energy bills: Solar panels let you generate your own energy to power your home, lowering your periodic electricity costs. You can eliminate your bills completely if you go off-grid.

How To Choose the Best Solar Company in Naperville

The more informed your provider search is, the better your solar installation will ultimately function. Make your choice based on the following important considerations.

Licensing and Training

In Illinois, the state Commerce Commission licenses distributed generation energy contractors, including residential solar contractors. You should also visit a company's website to learn about its private accreditations. Two of the most respected are the Solar Heating Installer and PV Installation Professional certificates, awarded 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 Naperville

Your photovoltaic panels' type will impact how much energy you can generate. Monocrystalline panels 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 have a low cost and are excellent for non-traditional roofs, but aren't recommended for large home installations.

You can also add battery backups and electric vehicle (EV) chargers. These will increase your total project price, but they can maximize your solar system's efficiency. Not all solar providers offer these extras, so look for a company that installs them if it's crucial for you.

Generally speaking, it will cost about $18,800 for a five-kilowatt solar array in Naperville. This table lists more specific pricing information for different solar panel types and system components in your area.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,248
Solar Polycrystalline$974
Thin-Film$569
Solar Battery$799
Solar Home EV Charger$2,996

Financing Solar Energy in Naperville

Solar installers use multiple different financing options to lower your costs and increase your savings. Though some providers offer unique payment plans, the most common are power purchase agreements (PPAs), solar loans, cash payments and solar leases. 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 incentives. Solar loans have the same benefits, though you'll pay more in total due to interest and fees. Like a home or auto loan, you'll pay a set monthly rate with potentially $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, akin to an electric bill. We typically don’t recommend these two options because you won't own the system and are disqualified from using solar incentives. Look for providers that offer two or more payment plans to find the right fit for your pocket.

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

The IRS allows you to claim a 26% federal tax credit on your new solar panels, so long as you purchase it before 2032. Local governments and utilities might also offer their own rebates, financing programs, and incentives that could save you more money.
