Key takeaways

  • One real no-cost route: Illinois Solar for All installs solar with no upfront cost for households at or below 80% of area median income, through approved vendors only. Check whether you qualify for Illinois Solar for All.
  • Everyone else signs a contract. “Free” or zero-down solar in Illinois means a loan, lease or power purchase agreement (PPA).
  • In a lease or PPA, the company collects the state money. On a typical ComEd system that is about $14,460 in Illinois Shines payments plus the $2,769 ComEd rebate.
  • Bill credits shrank in 2025. New ComEd, Ameren and MidAmerican solar customers since January 1, 2025 get credit for the supply part of the bill only.
  • No federal tax credit for a home system installed after December 31, 2025.
About this review

We checked every Illinois number on this page against the program, utility or IRS source linked beside it. Program and utility figures were checked between September 29 and October 5, 2026. The writer and checker named above link to their profiles. This guide explains offers and programs; it is not tax, legal or financial advice.

How we choose sources and correct errors: editorial process and content standards.

Illinois is one of the few states where “free solar” is not automatically a sales trick. The state runs an income-qualified pathway, Illinois Solar for All, next to the standard Illinois Shines incentive. That cuts both ways: a real program exists for households that qualify, and it lends every door-to-door pitch a credibility it has not earned.

The job in Illinois is telling the state’s program from the salesperson’s version of it. The dividing line is simple: the real pathway runs through approved vendors under state rules. Everything else is a contract wearing the program’s clothes.

Check Illinois Solar for All first

If your household income is low enough, this is the only route in Illinois where you can get solar without paying upfront and without a payment that eats your savings. You apply through the program, not through EcoGen.

Illinois Solar for All: eligibility and approved vendorsRun by the Illinois Power Agency, with Elevate as program administrator. Checked October 5, 2026.

Who can apply
Households with income at or below 80% of the area median income
What you pay
No upfront cost, and yearly payments of no more than half the value of the power your panels make
Who installs
Only the program’s approved vendors
Status
Applications run in windows. The first 2026-27 window for homes closed on September 25, 2026. If money was left, a rolling window opened October 12, 2026 and runs until May 31, 2027 or until the budget of about $8.9 million is used; if the first window was oversubscribed, projects are picked on January 13, 2027. Check the program site for its status. Renters can ask about its community solar option.

Zero-Down Solar in Illinois: Loan, Lease or PPA

If you do not income-qualify, Illinois zero-down solar means one of three contracts. Illinois adds a twist: much of a system’s value comes from the Illinois Shines payment for its renewable energy credits (RECs, one for each 1,000 kWh the panels make), and whoever owns the system is the one paid for them.

Zero-down options in Illinois and who gets the state and utility money
Zero-down optionWho owns the panelsWho gets the Shines payment and rebateWhat you pay
Zero-down solar loanYouThe Shines payment is set for an owned system, with a $20 extra per credit, and ComEd or Ameren pays you the rebate. Your installer holds the REC contract, so ask how much it passes on.Loan payments, plus what remains on your bill
Pros and cons in Illinois: zero-down loan

Pros

  • The Shines price for an owned system includes the $20 extra per credit that leases never get.
  • ComEd and Ameren pay the $300 per kW rebate to you, after the system is switched on.
  • Owned solar is assessed for property tax at no more than a conventional heating and cooling system.

Cons

  • Your installer holds the REC contract. If it keeps part of the Shines value, your price stays higher.
  • Half the Shines money is paid at start-up and the rest over six years, so it does not all lower the loan on day one.
  • Some loans still assume a lump-sum payment from the federal tax credit, which ended for systems installed after December 31, 2025.

Can fit if: you can get a written price that shows how much of the Shines value and the rebate is passed on to you.
Solar leaseThe companyThe company, at the lower lease price per credit, and the rebateA monthly payment that may rise each year, plus what remains on your bill
Pros and cons in Illinois: lease

Pros

  • Nothing to pay upfront, and no loan to qualify for.
  • The company handles Shines paperwork, repairs and monitoring.

Cons

  • The company collects the Shines payment and the rebate, about $14,460 plus $2,769 on a typical ComEd system.
  • The payment was set against credits that shrank for new customers on January 1, 2025.
  • A yearly escalator can push the payment above your savings.

Can fit if: the first-year payment is well below what you save at today’s supply-only credit, with any escalator included.
Power purchase agreement (PPA)The companyThe company, the same as a leaseA price per kWh the panels make, plus what remains on your bill
Pros and cons in Illinois: PPA

Pros

  • You pay only for the kWh your panels make.
  • No upfront cost, and the company handles repairs.

Cons

  • The company keeps the Shines payment and the rebate, the same as a lease.
  • Your exported power earns supply-only credit, so the PPA price must beat that, not your full bill rate.
  • A yearly price increase can erase the gap.

Can fit if: the PPA price per kWh, after any yearly increase, stays below the supply price on your ComEd, Ameren or MidAmerican bill.
Who collects the incentive money on a typical ComEd system

A 9.23 kW system over 15 years of Illinois Shines payments. EcoGen calculation from the 2026-27 REC prices and ComEd’s rebate.

Incentive money on a typical ComEd system, owned versus leased
Owned: Illinois Shines paymentabout $18,040
Owned: ComEd rebate$2,769
Lease or PPA: Illinois Shines payment to the companyabout $14,460
Lease or PPA: ComEd rebate to the company$2,769

Best case for an owned system: it assumes your installer passes the full Shines value on to you. Many keep part of it. Ameren and MidAmerican homes are in the lower price group, and MidAmerican pays no rebate.

So the Illinois question for any zero-down offer is: who claims the RECs, at what assumed price, and what happens to my payment if the price block fills before my project is submitted? A company that knows the program answers in writing. A company borrowing the program’s name changes the subject. To compare loan terms, APRs and lifetime cost, use our solar financing guide.

ComEd, Ameren Illinois and MidAmerican: The Credit a Lease Is Priced Against

Every Illinois lease or PPA is priced against your utility’s bill credits, and those changed on January 1, 2025. New ComEd, Ameren Illinois and MidAmerican customers earn credit against the supply part of the bill only, while delivery charges apply to every kilowatt-hour you draw. Credit you do not use keeps rolling forward to later bills. A payment sized to the old full-retail credit can outrun the savings. Systems connected by the end of 2024 keep full credit for 30 years.

Ask the company in writing

Shines prices are for systems up to 10 kW AC in Program Year 2026-27 (Illinois Power Agency). Rebate: ComEd terms and Ameren Rider CGR. Credits: ComEd net metering FAQ. Ask any company to name your utility and the credit rate it modeled, in writing.

You Likely Will Not Qualify If

  • Your income is above the program limit. Illinois Solar for All is income-qualified. There is no polite workaround, and a vendor who suggests one is a red flag.
  • Your roof needs replacing. No program pays to put equipment on a roof that will come off in a few years.
  • You are on a co-op or city utility. Rules and credits are built around the big utilities. Check your utility’s rules first.
  • You want the incentives and zero down at once. With a lease or PPA, the company takes the incentive money. That is the trade; make it knowingly.

The Ten-Minute Illinois Audit

  1. Is this Illinois Solar for All, a lease, a PPA or a loan?

    Get the word in writing. A zero-down offer is still one of these.

  2. If it claims the program, is the vendor on the approved list?

    Check the program’s own vendor list before you share income documents.

  3. What is the cash price next to the monthly payment?

    Compare it with what solar costs in Illinois (a typical 9.23 kW system is about $28,152 before incentives).

  4. Who claims the RECs, and at what assumed price?

    Ask to see the numbers on the Illinois Shines disclosure form, and who absorbs the difference if the price block fills before your project is submitted.

  5. Can the payment rise, and what happens when you sell?

    Find any yearly increase (an escalator), the transfer rules and the buyout price. See solar lease exit options.

Pause if a seller says everyone qualifies for the state program, will not name the program in the paperwork, or pushes you to sign today.

Learn the solar scam warning signs and compare several written offers. Check bidders against our Illinois solar companies guide.

Compare Illinois Quotes, Owned and Zero-Down

Ask every installer for the cash price, the zero-down price and the REC value it assumed. Comparing those side by side shows who keeps the Illinois Shines money.

Frequently Asked Questions

Are solar panels free in Illinois?

For income-qualified households, Illinois Solar for All can remove the upfront cost under state rules. For everyone else, “free” means a lease, PPA or zero-down loan: real contracts with real costs.

Is there a no-cost solar program in Illinois?

Yes, one: Illinois Solar for All, for households at or below 80% of area median income, delivered through approved vendors. Eligibility is checked, capacity is limited and the terms come from the program, not the salesperson.

Can I get zero-down solar in Illinois?

Yes. Many installers offer zero-down loans, leases and PPAs. With a loan you own the system and the Shines payment and rebate are tied to your system. With a lease or PPA the company owns it and collects them. Compare the cash price and total payments first.

How do I know if an Illinois free solar offer is the real program?

Check the vendor on the program’s approved vendor list, and ask for the program name in the paperwork. “Everyone qualifies” and pressure to sign mean it is a private contract, whatever name the pitch borrows.

Who gets the Illinois Shines money in a lease or PPA?

The system’s owner, which in a lease or PPA is the company. On a typical ComEd system that is about $14,460 over 15 years, plus the $2,769 rebate. That value is built into your payment on the company’s terms. Ask what price it assumed.

Is zero-down solar worth it in Illinois if I do not qualify for the program?

Sometimes. Homes with high power use and good roofs can come out ahead, but only when the payment is tested against today’s supply-only credits and realistic REC values, and compared with the cash price of owning the system.
