Illinois homeowners pay about 20.47 cents per kWh (EIA residential retail price, April 2026), and the state’s standout perk is Illinois Shines, the Adjustable Block Program that pays for your solar renewable energy credits (SRECs). Add Illinois Solar for All for income-qualified homes and net metering through ComEd and Ameren Illinois, and this is one of the strongest incentive stacks in the Midwest.
Illinois has quietly become one of the better solar states in the middle of the country, and the reason is policy, not sunshine. The state pays homeowners for the renewable energy credits their panels generate through Illinois Shines, layers on a dedicated low-income program in Illinois Solar for All, and keeps net metering in place through its two big utilities. This page covers what Illinois solar incentives look like in 2026, how the SREC payment works, how net metering credits your power, which utility serves you, and how to tell if solar is worth it for your home.
What solar costs in Illinois, and what your roof makes
Solar pays in Illinois because of the rate it replaces and the incentives stacked on top. Illinois’s average residential electricity price is about 20.47 cents per kWh (EIA retail sales, residential Illinois, as of April 2026), which sits above the national average, so every kilowatt-hour your roof makes offsets one you would otherwise buy at that price. Rising delivery charges from ComEd and Ameren Illinois have pushed bills higher in recent years, which is part of why interest in rooftop solar keeps climbing across Cook County and downstate.
Illinois gets enough sun to make solar work, even this far north. According to MySolarFY’s analysis (as of August 2026), a typical 7 kW rooftop system in the Chicago area is modeled to produce about 9,159 kWh per year, worth roughly $1,875 at Illinois’s 20.47 cents per kWh residential rate (NREL PVWatts v8 run, NSRDB typical-year data). Central and southern Illinois see a little more sun, so a comparable system near Springfield models closer to 9,600 kWh per year. Actual output depends on your roof’s pitch, orientation, and shading, so estimate your own roof with NREL’s free PVWatts calculator before you size a system.

Illinois Shines: the SREC payment that anchors the deal
Illinois Shines is the payment that anchors solar economics in the state. Officially the Adjustable Block Program, it pays you for the solar renewable energy credits (SRECs) your panels generate over 15 years (Illinois Power Agency, as of August 2026). One SREC represents the environmental value of the clean power your panels make, and the state buys that value from you, usually as an up-front lump sum paid through your installer that lowers your net system price.
The payment is set in blocks, and the value changes as blocks fill. The Illinois Power Agency sets SREC prices in program blocks that adjust over time, which is where the “adjustable block” name comes from, so the exact figure depends on your system size and the current block when you apply (Illinois Shines program site, verify current block pricing). Because the money often arrives as a price reduction rather than a check you chase, it is easy to miss when you compare quotes, so ask each installer to show the SREC value as a separate line. For how programs like this stack up nationally, see our solar incentives overview, or see the full Illinois breakdown in our Illinois solar incentives for 2026.
Illinois solar incentives at a glance
Illinois builds its value from a performance payment and net metering rather than a single state tax credit. Here is what each piece does in 2026 and the fine print worth knowing.
| Incentive | What it does | 2026 value and status | Source |
|---|---|---|---|
| Illinois Shines (Adjustable Block Program) | Pays you for your system’s SRECs over 15 years | Active; block pricing set by the Illinois Power Agency, paid through an approved vendor | Illinois Power Agency |
| Illinois Solar for All | Brings solar to income-qualified households at no up-front cost | Active statewide for eligible low-income homes | Illinois Power Agency |
| Net metering | Credits exported power against imported power | Available via ComEd and Ameren Illinois; terms transitioning, verify | Illinois Commerce Commission |
| Property-tax treatment | Values a solar system for property tax like a conventional system | Special assessment available; verify current terms | DSIRE Illinois |
| Federal residential (Section 25D) | A 30% homeowner credit | Ended for expenditures made after December 31, 2025 | IRS |
Heads up on the federal change: the 30% federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, under the One Big Beautiful Bill Act (IRS, as of January 2026), so an Illinois homeowner who buys solar with cash or a loan in 2026 cannot claim it. Illinois Shines and net metering are separate state programs and were not affected. Confirm every figure against the linked source, and ask a tax professional about your own situation. MySolarFY does not provide tax advice.
Net metering in Illinois: available, and transitioning
Illinois still offers net metering through ComEd and Ameren Illinois, but the terms are transitioning. Net metering credits the power your panels export to the grid against the power you pull back, which is a large part of what makes rooftop solar pay. In Illinois, what your exports are worth now depends on your utility, your rate class, and when your system interconnects, so the old assumption that every new customer gets the same one-to-one retail credit no longer holds automatically (Illinois Commerce Commission, verify current terms).
Because the details are moving, confirm your terms before you sign. Ask your installer and your utility exactly how your exports will be credited, whether a smart-inverter or distributed-generation rebate applies, and what happens to unused credits at your annual true-up. For the mechanics of how export credits work in general, see how net metering credits your solar exports. Getting this right matters, because your net-metering credit and your Illinois Shines SREC payment together carry most of the savings.
Which Illinois utility serves you, and how it credits solar
Your utility sets your rate, your net-metering terms, and your interconnection paperwork. Illinois is served mainly by two large investor-owned utilities that split the state north and south, plus a set of municipal utilities and rural co-ops in specific communities.
| Utility | Type | Rough service area | Residential solar in 2026 |
|---|---|---|---|
| Commonwealth Edison (ComEd) | Investor-owned | Northern Illinois, including Chicago and the suburbs | Illinois Shines SRECs; net metering, terms transitioning |
| Ameren Illinois | Investor-owned | Central and southern Illinois | Illinois Shines SRECs; net metering, terms transitioning |
| Municipal utilities and co-ops | City or member-owned | Specific downstate cities and rural areas | Set locally; confirm with your provider |
Most Illinois homeowners looking at solar are ComEd customers in the Chicago area and northern counties, or Ameren Illinois customers through the central and southern parts of the state. Both connect to Illinois Shines, so the SREC payment is available statewide, but the interconnection and net-metering paperwork runs through your specific utility. For a ComEd-specific walkthrough, see our ComEd solar guide, and for a city-level look at permitting, costs, and installers, see our Chicago solar guide. Enter your ZIP above and we match you with installers who know your utility’s rules.
Illinois Solar for All: solar for income-qualified homes
Illinois Solar for All is a dedicated program that makes solar reachable for lower-income households. It is a separate state program from Illinois Shines, aimed at income-qualified homeowners and renters, and it is designed so participating households take on no up-front cost and see a real reduction on their energy bills (Illinois Power Agency, as of August 2026). Eligibility is tied to household income and program capacity, so the details and availability change over time.
If your income qualifies, this is often the most affordable path to solar in the state, but availability depends on program funding and approved providers, so verify current eligibility and openings before you count on it. A licensed installer who works with the program can tell you whether your household qualifies and what the current terms look like.
Is solar worth it in Illinois?
For many Illinois homeowners, yes, because the incentives do the heavy lifting. An above-average electricity rate, the Illinois Shines SREC payment, net metering, and a low-income path in Solar for All combine into a reasonable payback even this far north. The honest catches are that the federal homeowner credit is gone as of 2026, net-metering terms are transitioning by utility, and SREC values shift by program block. Whether it pays for your specific home comes down to your roof, your utility, and your usage. For a deeper look at the numbers, see our guide on whether solar panels are worth it, and for the federal picture see what the federal solar tax credit change means in 2026.
How you pay decides which benefits you keep. The 30% federal homeowner credit (Section 25D) ended for expenditures made after December 31, 2025, so it is not part of a 2026 purchase on any path. If you buy the system with cash or a loan, you own it and take the Illinois Shines SREC payment and net-metering credits directly. If you lease or sign a power-purchase agreement, a third party owns the panels, you typically pay little or nothing up front, and the company that owns the system claims any commercial credit (Section 48E) and often the SRECs, not you. MySolarFY matches you with licensed Illinois installers so you can compare real local quotes side by side, with no obligation.

Frequently asked questions
What solar incentives does Illinois offer in 2026? Illinois offers Illinois Shines, the Adjustable Block Program that pays you for your system’s SRECs over 15 years; Illinois Solar for All for income-qualified households; and net metering through ComEd and Ameren Illinois. There is no single state solar tax credit, because the SREC payment plays that role instead. The 30% federal homeowner credit ended for expenditures made after December 31, 2025. Confirm current terms with each source before you sign.
What is Illinois Shines and how does the SREC payment work? Illinois Shines, officially the Adjustable Block Program, pays you for the solar renewable energy credits (SRECs) your system generates over a 15-year period through a contract with a state-approved vendor. The Illinois Power Agency sets prices in program blocks that adjust over time, so the exact value depends on your system size and the current block. The payment usually arrives as an up-front reduction on your system price, so ask your installer to show it as a separate line.
Does Illinois still have net metering? Yes, net metering is available through ComEd and Ameren Illinois, but the terms are transitioning. What your exports are worth depends on your utility, your rate class, and when your system interconnects, so the old assumption that every new customer gets full one-to-one retail credit no longer holds automatically. Verify your current net-metering terms with your utility and the Illinois Commerce Commission before you commit.
Who is my Illinois utility, and does it credit solar? Most Illinois homeowners are served by Commonwealth Edison (ComEd) in northern Illinois and the Chicago area, or by Ameren Illinois in the central and southern parts of the state; some communities are served by municipal utilities or rural co-ops. Both major utilities connect to Illinois Shines, so the SREC payment is available statewide, and both offer net metering with terms that are transitioning. Confirm your specific utility’s current policy before you commit.
Is there an Illinois state solar tax credit? No, Illinois does not offer a state income-tax credit for residential solar. Instead, the state’s value comes from the Illinois Shines SREC payment, net metering, Illinois Solar for All for income-qualified homes, and a property-tax special assessment that keeps solar from raising your assessed value. These programs are separate from the federal credit that ended after December 31, 2025.
What happened to the federal solar tax credit in Illinois? The 30% federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, under the One Big Beautiful Bill Act, so an Illinois homeowner who buys solar in 2026 with cash or a loan cannot claim it. A separate commercial credit (Section 48E) can apply to leased and PPA systems, but the business that owns the system claims it, not the homeowner. Illinois Shines and net metering are state programs and were not affected.

MySolarFY is a free service that matches homeowners with licensed solar installers. We are not an installer, financing company, or government program. “No up-front cost” refers to qualifying lease or PPA financing, where eligible homeowners may have no out-of-pocket cost at installation. Lease and PPA terms typically run 20 to 25 years, may include an annual price escalator, and total payments may exceed the cost of a cash purchase. Homeowners do not get the federal residential credit that ended after December 31, 2025; on a leased system the company that owns it claims any commercial credit and often the SRECs.
