Illinois at a glance
Illinois protects solar buyers through its consumer fraud law, the home repair law, and the Illinois Shines incentive program, which has its own disclosure form, complaint process, and penalties for vendors. Net metering also changed for new systems on January 1, 2025.
If you were misled, you have options
Being told your bill would disappear, that the system was free, that a tax credit would pay off the loan, or that you were only signing up for an inspection can all matter, even long after a cancellation window has closed.
- Your state's consumer protection law. Every state has a law against deceptive and unfair business practices. False promises about savings, costs, tax credits, or who you were dealing with may fall under Illinois's law.
- Missing paperwork and disclosures. Many states require specific disclosures and a written cancellation notice. If you never received them, a deadline may not have started, or the contract may have other problems.
- Your lender may share responsibility. When a seller arranges your financing, federal rules often let you raise the same claims against the lender that you have against the seller, up to the amount you paid. Check your loan for a notice about the FTC Holder Rule.
- Official complaints. Complaints to Illinois's agencies are free, create a record, and can lead to mediation or an investigation.
- Professional help. A solar attorney or solar exit company can review your documents and tell you which of these options fit your situation.

Illinois cancellation window
3 business days (15 if you are 65 or older)
If a salesperson sold you a home solar system or other purchase of $25 or more while physically at your home, you can cancel before midnight of the third business day after you signed. The clock does not start until you receive a written Notice of Cancellation and an address to send it to.
Source: 815 ILCS 505/2B · Checked November 7, 2026
Conditions that matter
- Cancel by signing and sending the Notice of Cancellation, or another written notice, to the seller's address. Keep a copy.
- The seller must refund everything you paid, and cancel any note or security interest, within 10 business days of receiving your notice.
- If you are 65 or older and an uninvited solicitor sold you a home repair or remodeling contract at your home, you have 15 full business days to cancel (815 ILCS 513/22).
- Does not apply if you negotiated the deal earlier at the seller's retail store, if the sale was handled entirely by mail or phone, if you waived the right in writing for a real emergency you requested, or if federal Truth in Lending rescission applies instead.
Illinois has no statewide solar-specific cancellation statute. If your installer participates in the Illinois Shines incentive program, program rules updated in April 2026 require contracts for systems of 25 kW or less to give you at least three calendar days to rescind after signing.
Canceling one agreement does not always cancel another. A separate loan, lease, or power purchase agreement can have its own terms, so check each document you signed. If the sale was made in Spanish or another language, read your rights when a contract is not in your language. To compare deadlines, see the cancellation period in every state.
Laws that protect you in Illinois
These are the state laws that come up most often in solar disputes here. Each one links to the official text or the agency that enforces it.
Consumer Fraud and Deceptive Business Practices Act
Prohibits deception, false promises, and misrepresentation in sales. It also covers the right to cancel many sales made at your home within three business days.
Home Repair and Remodeling Act
Home repair work over $1,000 requires a written contract, and the contractor must give you the Attorney General's "Home Repair: Know Your Consumer Rights" pamphlet before you sign. If you are 65 or older and the sale was made at your home, you have 15 business days to cancel.
Illinois Power Agency Consumer Protection Handbook
Illinois Shines consumer protections
If your system is in the state's Illinois Shines incentive program, the company must give you a standard disclosure form and have you sign it before you sign the contract. The program investigates complaints and can suspend vendors, and it publishes a list of complaints and suspended companies.
How your utility credits solar in Illinois
Supply-only net metering for systems connected after 2024
Under the Climate and Equitable Jobs Act, ComEd, Ameren, and MidAmerican customers who connected new systems after December 31, 2024 receive supply-only net metering. Exported power is credited at the electricity supply rate, not the full retail rate that includes delivery charges. ComEd and Ameren customers can get a one-time distributed generation rebate instead. Systems connected before the deadline keep full retail net metering. A 2025 or later quote that assumed full retail credit overstated savings.

Illinois solar questions
What is Illinois Shines?
It is the state's solar incentive program, run for the Illinois Power Agency. Participating companies must follow its consumer protection rules, including the standard disclosure form.
How do I file a complaint with Illinois Shines?
Contact the program administrator at admin@illinoisshines.com or (877) 783-1820. You can also file with the Illinois Attorney General.
Why are my credits lower than my neighbor's?
If your neighbor connected before January 1, 2025, they likely have full retail net metering. Newer systems get supply-only credits, which are worth less per kilowatt-hour.
