The short answer: Under Section 2B of the Illinois Consumer Fraud and Deceptive Business Practices Act, 815 ILCS 505/2B, buyers in a home solicitation sale can cancel within three full business days, and the cancellation period doesn’t begin until the seller provides the required notice. Illinois also requires distributed generation installers to be certified by the Illinois Commerce Commission.

Cancelling a solar contract in Illinois

Illinois ties the start of the three-day window to the seller’s notice. If you never received the required notice of cancellation, ask a reviewing attorney whether your window ever began.

Illinois solar rules

The Illinois Consumer Fraud and Deceptive Business Practices Act lets consumers recover actual damages and, in some cases, punitive damages and attorney’s fees. The Illinois Commerce Commission certifies distributed generation installers and enforces its rules for them.

How Illinois utilities credit solar

Illinois changed net metering for new customers of its large utilities starting in 2025, crediting exported power at a lower supply-based value and pairing it with an upfront distributed generation rebate. Proposals written under older rules may overstate ongoing savings.

Solar Cancellation HQ is not a law firm and does not provide legal advice. This page is general information, and reading it or submitting a form does not create an attorney-client relationship. Not every contract qualifies, and no outcome is guaranteed. We never advise anyone to stop making payments on a solar loan, lease or PPA. Laws and utility rules change, so verify before acting.
