What is Illinois Shines?

Illinois Shines is the everyday name for the Adjustable Block Program — the state's main solar incentive, run by the Illinois Power Agency. Here's the plain version: your panels earn credits for the clean power they make, the utilities are required by law to buy those credits at published prices, and that money flows back into your solar deal. It was created by state law in 2016, expanded in 2021, and it's the largest Illinois-specific solar incentive.

One credit — a REC — equals one megawatt-hour (1,000 kWh) of production. A typical home system earns several of them every year. Residential systems are signed up for a 15-year delivery term based on a state-approved estimate of your roof's production — not metered month to month. The 2026–27 program year opened June 1, 2026 with fresh capacity.

How much does Illinois Shines pay in 2026?

For the 2026–27 program year, a home-sized system (up to 10 kW AC) earns $80.77 per REC in ComEd territory and $70.37 per REC in Ameren territory — plus a $20-per-REC bonus when you own the system with cash or a loan. Larger home systems have their own published tier, and every figure below comes straight from the state's official price sheet.

One sizing note worth knowing: the program measures systems in kW AC — a little below the DC panel rating printed on most quotes. Your installer's paperwork states both.

As a scale illustration, a customer-owned 7 kW system in ComEd territory can represent roughly $12,000–$13,000 of gross REC value across the 15-year term. The worked math — and the caveats that come with it — lives on our Illinois Solar Facts hub; the full incentive stack is on our Illinois Solar Incentives guide. And since RECs are earned per megawatt-hour your roof produces, system size drives the count — here's how to size a system from your actual usage, not your square footage.

Where does the money actually go?

This is the single most misunderstood thing about Illinois Shines — so here it is as a picture. The utility buys your RECs. The payments go to your Approved Vendor. Your benefit arrives as a lower price on your contract, and you should see it stated in dollars, in writing.

Payment structure: Public Act 104-0458, effective June 1, 2026. Never quarterly, and never a check mailed to the homeowner.

Estimate your own REC value

Three picks and you'll have a working number. This is simple arithmetic on the state's published prices — an illustration, not a quote, and not what lands in your mailbox.

Who actually receives the money — and when?

Not you, directly — and never every quarter. Under state law (Public Act 104-0458, effective June 1, 2026), REC payments go to the project's Approved Vendor: half when your system switches on, and the rest in equal yearly payments over the next six years. Your benefit should arrive as a lower contract price or better terms — not a check in the mail.

That makes one question non-negotiable when comparing offers: "How, exactly, is the REC value reflected in my price — stated in dollars, in writing?" Your Illinois Shines Disclosure Form should match what the salesperson said; if the pitch and the form differ, believe the form. Any pitch describing quarterly homeowner REC checks is describing the program wrong — twice. And since the REC value shows up as a discount on the system's price, it helps to know what solar actually costs in Illinois before judging whether a "discounted" number is genuinely good — or just run the quote through our pre-signature checklist.

The $20 owner bonus — and the fine print that protects you

If you buy your system with cash or a loan, every REC earns $20 more — that's $100.77 per REC in ComEd territory and $90.37 in Ameren territory on home-sized systems. The state added it in 2026 specifically because the federal tax credit ended for buyers (what expired and what didn't). But it isn't automatic, and the rules are worth 60 seconds of your attention.

• Owned systems only. "Customer-owned" means you bought it — cash or loan. A lease or PPA earns the base REC price, without the bonus.
• No federal credit on the same system. The vendor must show the project hasn't taken — and won't take — a federal investment or residential clean energy credit. For a 2026 purchase that's already the reality.
• It's checked twice. The vendor attests to ownership when your project is first submitted, and again at final verification after installation. If ownership changes in between, the bonus comes off.
• It must appear on your Disclosure Form. The state requires the adder to be disclosed there. If your form doesn't show it and you're buying the system, ask why before you sign.

Who are Approved Vendors and Designees — and what's the Disclosure Form?

An Approved Vendor is the state-registered company that submits your project into Illinois Shines and holds the REC contract. A Designee — often the installer or sales company you actually deal with — works under an Approved Vendor's registration. Before you sign anything, they must give you the state-required Disclosure Form showing system size, projected production, price, and terms.

Every legitimate Illinois Shines pitch can name its Approved Vendor. Confirming that name takes about five minutes and filters out most bad actors before they cost you anything — here's exactly how to verify a vendor on the official list. Refusal to name the vendor or produce the Disclosure Form ends the conversation. Problems with a seller go to the Illinois Shines Consumer Complaint Center.

What is Illinois Shines not — and what stacks with it?

It's one of three separate value streams — and it's none of the others. Knowing the difference keeps a salesperson from counting the same dollar twice in your quote.

• Net metering is a different program — it governs bill credits for the power you export, covered in depth in our ComEd Solar Guide.
• The smart-inverter rebate ($300/kW solar; $300/kWh battery, with conditions) is a separate one-time utility payment — see the facts hub.
• The federal tax credit ended December 31, 2025 for cash and loan buyers — what expired and what didn't: did the solar tax credit end?
• There is no Illinois state solar tax credit — despite guides claiming one worth up to $10,000. Illinois Shines RECs are the state's real money, and the myth has its own page: does Illinois have a state solar tax credit?
• Illinois Solar for All is the separate income-eligible pathway with its own rules — overview here.

All three state-level pieces — Shines RECs, net-metering credits, and the rebate — stack on the same system.

Is Illinois Shines still available right now?

Yes — the 2026–27 program year opened June 1, 2026 with fresh capacity. But that capacity comes in limited blocks that fill up through the year, so we never publish a live availability number here. Check the program's official Block Capacity Dashboard yourself — and treat any salesperson's countdown as unverified until you've seen it there.

How do you actually get Illinois Shines?

You never file anything with the state — the Approved Vendor does. Your side of it is simpler than most people expect:

1. Disclosure Form first. You get it before you sign anything — size, projected production, price, terms, and (if you're buying) the $20 owner bonus.
2. Project submission. The Approved Vendor submits your project to the state for review before installation.
3. Installation, under local permits and ComEd/Ameren interconnection approval.
4. Post-installation verification confirms the system as built — and re-checks the ownership bonus.
5. Switch-on. The system gets permission to operate — which triggers the first 50% payment to the vendor.
6. Remaining payments flow to the vendor in equal yearly amounts over the next six years.

Your leverage points are the Disclosure Form, the contract, and knowing which Approved Vendor holds your project.

Illinois Shines FAQ

Is Illinois Shines legit, or a scam?

The program is real: it was created by Illinois law in 2016, expanded in 2021, and is run by the Illinois Power Agency with prices published by the state. What isn't always legitimate is who shows up selling it. The five-minute filter: verify the company on the official Approved Vendors & Designees list before you engage, and report problems to the program's Consumer Complaint Center.

Is Illinois Shines the same as the federal solar tax credit?

No. Illinois Shines is a state program and remains active for 2026–27. The federal residential credit expired December 31, 2025 and can't be claimed on 2026 cash or loan purchases — the two are unrelated programs with unrelated rules.

Do homeowners get an Illinois Shines check every quarter?

No — twice over. Payments go to the Approved Vendor, not the homeowner: 50% at switch-on plus the rest in equal yearly payments over the next six years, under Public Act 104-0458. Your benefit typically arrives as a lower contract price.

How much is the $20 customer-owned adder actually worth?

It stacks on the base price when you own the system with cash or a loan: $100.77 per REC in ComEd territory and $90.37 in Ameren territory on the 0–10 kW AC tier — a concrete, sourced reason ownership out-earns third-party deals on REC value.

Do I get the $20 owner bonus automatically?

No. It applies only to customer-owned home systems, the vendor must show the project takes no federal credit, ownership is attested when the project is submitted and re-checked at final verification, and the adder must be disclosed on your Disclosure Form. Buying with cash or a loan and it's not on your form? Ask why, in writing, before signing.

Does a lease or PPA still get Illinois Shines value?

Yes — at the base REC price, without the $20 bonus, paid to the system's owner. Whether any of that value reaches you depends entirely on the offer's pricing, so ask for the pass-through stated in dollars, in writing.

How many RECs will my system produce?

One REC per megawatt-hour. As an illustration, a 7 kW system producing around 1,200 kWh per kW annually generates roughly 8.4 MWh a year — about 126 RECs across the 15-year term. Your actual count comes from the program's production model for your specific roof, and the count starts with system size: how to size a system from your real usage.

What if my system is bigger than 10 kW?

Larger home systems have their own published tier: over 10 kW AC and up to 25 kW AC pays $79.21 per REC in ComEd territory and $60.92 in Ameren territory for the 2026–27 year, and the $20 owner bonus still applies to customer-owned systems. Note the program measures kW AC — slightly below the DC panel rating on most quotes.

What is the Illinois Shines Disclosure Form?

The standardized, state-required document every Approved Vendor or Designee must provide before contract signing — system size, projected production, price, and terms in one place. No form, no signature. If the form and the pitch differ, believe the form.

Can Illinois Shines run out of money?

Capacity is limited and released in blocks each program year — blocks can fill, and new projects may wait for reopened capacity. Check current status on the official Block Capacity Dashboard rather than relying on any sales claim about scarcity.

What happens after the 15-year REC contract ends?

The REC payments end — the contract is an incentive with a fixed term, not the system's lifespan. Your panels keep producing, your net-metering credits continue under your utility's rules, and nothing about the system itself changes at year 15.

Is Illinois Shines the same as Illinois Solar for All?

No. Illinois Solar for All is the separate income-eligible pathway, with its own approved vendors, its own rules, and stronger guaranteed-savings protections. Illinois Shines is the general program covered on this page. A household can qualify for one, the other, or neither — not both on the same system.

Does Illinois Shines stack with net metering and the smart-inverter rebate?

Yes. They're three separate programs that apply to the same system: Shines pays for RECs, net metering credits your exports, and the $300/kW smart-inverter rebate is a one-time utility payment. Each has its own rules.
