Illinois produces enough solar energy to power 217,000 homes despite some of the least amount of sunlight in the country. With great state-level support, homeowners are finding it worth their time to make the switch. If you’re considering solar panels in Illinois, we’ve got you covered. We discuss expected costs, important solar factors, and potential savings below.
Average Cost of Solar Panels in Illinois
Featuring one of the country’s major commerce hubs, it’s no surprise that homeowners can buy solar panels in Illinois at a decent rate. The average cost for equipment in the Prairie State is $2.57, which is lower than in most places. For a 6kW system, Illinoisans can expect to budget around $15,420 before incentives.
However, homeowners might not feel so motivated to make the switch; with an average utility bill of $94.38 a month, Illinoisans pay the least in the country for electricity. This means that it’ll take longer to pay off a solar panel system with offsets, resulting in a smaller return.
Still, those that are equally interested in improving their carbon footprint can cut the cost of an array with the federal solar tax incentive. This benefit comes in the form of a 30% credit off federal taxes at the end of the year for which the system was installed. In Illinois, people can reduce the cost of a 6kW solar array from $15,420 to $10,794.
How Much Solar Do Illinoisans Need?
While the previous example presents the typical price of solar across the Prairie State, it might not apply to your personal household. Because Illinois has varying geography and weather patterns, you’ll want to calculate the size of the array that will cover your electricity usage. To determine wattage, you’ll need to divide your daily power by the amount of peak sun in your region. Here’s how to do it with Illinois averages.
Based on state research, Illinoisans use about 24.0kWh a day (721kWh a month). When divided by the state’s average peak sun of 3.14 hours per day, we’ll need a 7.7kW solar panel system to cover all of our power. A system of this size might cost homeowners in Illinois around $19,789.
Now that you know how to calculate the ideal wattage for your household, you can find out how much you need to budget. To find out how much sunlight you get, follow this Illinois sun chart.
Illinois Solar Cost Factors
As previously mentioned, the Prairie State features a diverse geography. Those living closer to the Great Lakes might need more solar panels than those living further south. In fact, those in Springfield might experience up to 4.8 peak sun hours a day. To discover how geography and sunlight can alter solar costs, compare Illinois to some of its neighboring states:
Additionally, the type of solar panels used in your array can have a noticeable effect on the overall cost. Generally, those that receive less sunlight will benefit more from monocrystalline panels, which are expensive but highly efficient. However, homeowners that live on the southern end of Illinois might take advantage of polycrystalline panels, the more affordable option.
Finally, Illinoisans should take the time to review installation companies. With stiff competition in Chicago, you’ll want to be wary of installers that undercut prices. You might be tempted to save money this way, but companies that do this typically use lower-quality equipment and provide less than standard warranties. With installation, you want a company that will stick around for the length of your system’s lifespan.
Best Solar Installers in Illinois
When suggesting the best solar installers in Illinois, we refer to EnergySage, a solar review company trusted by the SEIA and the USDoE. The review company screens each company they recommend using a list of qualifications which include:
- Many years of industry experience

The installer has all the necessary certifications and outdoes the competition with a 15-year workmanship warranty in some states.
While All Energy Solar might seem good, you might feel more comfortable using a local installer. If that’s the case, you’ll want to consider RxSun. With their headquarters located in Chicago, you’ll know that your contractors are knowledgeable about the state’s conditions. RxSun also offers one of the best warranties in the industry, covering your installations for 30 years.
Can Solar Energy Save Illinoisans Money?
Featuring low electricity rates and some of the cloudiest weather in the country depending on location, homeowners in Illinois might not feel so inclined to make the switch to solar. And because Illinoisans pay so little for power as it is, their total net return won’t be as impressive as it is in other states. Still, the potential for savings exists for those considering solar panels in Illinois.
First, homeowners need to know how long it takes to cover the cost of an array. Typically, Illinoisans pay about $1,132.56 a year for electricity. If homeowners in the Prairie State use a 6kW system to offset that yearly bill, it would take 13.6 years to pay it off. That’s about as long as it gets anywhere in the country.
After the system is paid off, you’ll start seeing net returns. Considering the lifespan of solar panels in Illinois is 20-25 years, homeowners would discover about $7,248 to $12,911 back in their pockets. While it might not feel as satisfying as in places like Arizona or Hawaii, that kind of return still makes a difference.
Solar Panels in Illinois: Rebates, Credits, and Incentives
If you’re wishing there were more ways to save money on solar panels in Illinois, you’re in luck. While the geography might not be the most conducive for solar energy, the Prairie State has some of the most progressive renewable standards around. Through credits, rebates, and other government regulations, Homeowners in Illinois can save thousands more on their installation.
Right off the bat, any qualifying Illinoisan can use the federal solar tax credit to save 30% of their purchase cost. This could result in a return of nearly $5,000 for some arrays.
