How much does solar cost in Illinois? (2026-2027)
The short answer: less than your current electric bill. The exact cost and savings of your system may vary depending on several factors (seen to the right), but homeowners typically report saving around 20 to 30 percent right out of the gate.
Your system size
The more panels you need to offset your energy needs, the more your system will cost.
Your roof size & layout
Your roof size and layout will ultimately determine how many panels you can fit and how efficient those panels will be
Cost of electricity
Your savings are the difference between what you pay now for electricity, and what you'll pay with solar. If your cost of electricity is high now, you have a better chance of having significant savings.
Your energy usage
The more energy you use, the more panels you need to offset that usage.
Local incentives
If your utility company doesn't have a strong net metering program, your savings will be significantly lower than a home that does.
Get paid for your solar energy in Illinois
Between the federal tax credit and significant solar rebates available exclusively to Illinois homeowners, thousands of dollars could be available for you to put towards your solar panels with no upfront cost.
Solar Tax Credit
Eligible homeowners can still deduct up to 30% of their solar power system’s costs by going solar with a Power Purchase Agreement.
Illinois Net Metering
Many utilities offer net metering, allowing excess electricity your system generates to help offset future electric bills. Policies vary by utility.
Property Tax Exemption
Adding solar increases home value — but Illinois exempts the upgrade from property tax assessments.

Frequently Asked Questions
How much do solar panels cost?
The cost of solar panels depends on the size of your home and how much energy you need to generate. That said, solar technologies have never been more efficient or affordable. Speak to one of our qualified, local energy advisors to get a free quote. Your energy advisor will work with you to help you decide if you are a good fit for solar.
How many solar panels do I need?
The number of solar panels required to power your home and lower your monthly electricity bill will be determined by several factors:
How much electricity your home uses
How much of your home you want to power with solar energy
How much space is available on your roof
How much sunlight your roof receives
Ultimately, the size of your system depends largely on the unique needs of your home and family. Speak to our friendly energy advisors to get an estimate on the number of solar panels your house requires.
How much of my home can be powered by solar?
That depends on your overall household energy usage relative to the total capacity of your solar array. Many homeowners desire a system size producing 100% of their energy usage needs, but that may not always be possible. Alternatively, if you plan to change your behavior, such as by purchasing an electric vehicle, you may wish to go a little larger than historical usage.
How long do solar panels last?
Our partners use exclusively Tier 1 solar panels, which offer high efficiency and long-term reliability. Using one of our installers, the solar panels in your system will produce for 25 to 30 years. And they come with a 25-year production guarantee* to ensure your panels continue to generate sufficient energy during that time period.
Will solar panels hurt my roof?
When installed correctly, getting solar panels installed on your home should not damage your roof. Make sure your solar system is installed by a licensed, qualified professional. They’ll make sure your roof is in good condition for a solar panel install.
What if I move?
That’s usually a smooth process. Your solar company will work with you to transfer the panels over to the new homeowner and you get to walk away without any strings attached.
