Illinois Shines: SREC Incentives for IL Homeowners
The Illinois Shines program pays Illinois homeowners for the clean energy their solar system generates — over a 15-year contract with values proposed to increase 34–43% in 2026. Here’s everything you need to know before enrolling.

What Is the Illinois Shines Program?
When a solar system generates electricity, it also produces Solar Renewable Energy Credits (SRECs) – one SREC for every megawatt-hour (MWh) of clean energy produced. Under the Illinois Shines program, Illinois electric utilities are required by state law to purchase these SRECs from eligible homeowners.
This creates a long-term revenue stream that runs alongside your electricity bill savings from net metering – and applies whether you finance your system through a loan or pay cash, as long as you own the system.
Think of it this way: your solar panels reduce your electric bill (net metering), and they simultaneously earn you SREC income that utilities pay for over 15 years (Illinois Shines). Both benefits stack together on the same installation.
Who administers it? The Illinois Power Agency (IPA) oversees the Illinois Shines program, setting SREC values and managing enrollment slots for each utility territory (Ameren and ComEd) annually.

Estimated total value of SRECs earned over the 15-year contract for a typical Illinois residential system.
15 years
Illinois utilities purchase SRECs at a fixed price for 15 years — providing predictable, long-term income from your solar system.
2 utilities
Both major Illinois utility territories participate in Illinois Shines. SREC values and slot availability differ by territory.

How Illinois Shines
Actually Works
From installation to SREC payment — here’s the complete process for an Illinois homeowner enrolling in Illinois Shines.
Get an Independent Energy Review
Before calling any installer, get a free Illinois Shines eligibility assessment. This confirms your utility territory, estimated SREC value, and whether current program slots are available — so you go into installer conversations fully informed.
-
Select an Illinois Shines Approved Vendor
Your solar installer must be an approved Illinois Shines vendor to enroll your system in the program. Not all installers are approved — this is one reason working with vetted installers matters.
-
Install Your Solar System
Illinois Shines certification & deep program knowledge - Your approved installer installs the system and handles the utility interconnection process — connecting your system to the Ameren or ComEd grid and obtaining the necessary approvals.
-
Enroll in Illinois Shines
Your installer submits your system for Illinois Shines enrollment through the IPA portal. A SREC contract is issued at the current program block price — locking in your SREC value for the full 15-year term.
-
Earn & Receive SREC Payments
As your system generates electricity, it earns SRECs. These are aggregated and sold to Illinois utilities at the contracted price — with payments flowing to you over the 15-year contract period. Simultaneously, your electric bill drops from net metering credits.

Illinois Shines SREC Values & Income
What your system can realistically earn through Illinois Shines — and why 2026 is a particularly favorable time to evaluate enrollment.
$10,000+
Total 15-Year SREC Income
For a typical 8–10 kW Illinois residential system, total SREC income over the 15-year contract period — at current proposed values — can exceed $10,000+ in aggregate payments.
$500+
Per Year in SREC Income
Annual SREC income depends on your system size and local production. Larger systems in high-sun locations earn more per year — our free review calculates your specific estimate.
+43%
SREC Value Increase
The Illinois Power Agency has proposed SREC value increases of 34–43% for the 2026 program year for eligible customer-owned systems — making this a particularly valuable enrollment window.
- Important: SREC values are set at the time of enrollment and fixed for your 15-year contract term. Future program years may have different values. The IPA sets new block prices annually — locking in current values before program year transitions is strategically important.
- Who qualifies
Illinois Shines Eligibility Requirements
Not every Illinois homeowner automatically qualifies. These are the key requirements – and the common reasons some homeowners don’t qualify for the full program benefit.
Illinois Location Required
Your home must be located in Illinois — specifically in an Ameren Illinois or ComEd electric service territory. Rural electric cooperative customers may have different program access.
New Installation Only
Illinois Shines is for new solar installations — not previously installed or existing systems. Your system must be newly installed after program enrollment.
Approved Vendor Required
Your solar installer must be a registered Illinois Shines approved vendor. The IPA maintains a list of approved vendors — our vetted installer network only includes approved vendors.
System Ownership
For the full Illinois Shines SREC benefit, you must own the solar system — not lease it. If you lease, the installer owns the SRECs. Ownership (cash or loan) is strongly recommended.
Slot Availability (Varies)
Enrollment slots are allocated per utility territory per program year. ComEd territory slots fill faster. Availability varies — checking your slot status before committing to an installer is important.
Utility Interconnection
Your system must be interconnected with your utility (Ameren or ComEd) and meet all technical requirements for grid connection before SREC enrollment is finalized.
- Strong eligibility profile: Illinois homeowner, Ameren or ComEd customer, planning to own (not lease) a new solar system through an approved installer, and checking enrollment availability before committing. Our free review confirms your specific eligibility and current slot status.
