THE SHORT ANSWER
The FTC says certain sales made at a home or temporary location can be canceled until midnight of the third business day, but the rule has exceptions. Read the applicability details before relying on it. [1]
Identify where and how the sale occurred
Write down whether the presentation and signing happened at your home, online, by telephone or at the seller’s permanent office. The FTC lists transactions the rule does not cover, including sales made entirely online, by mail or by telephone. [1] Preserve invitations and appointment messages.
Find the required documents
For a covered door-to-door sale, the federal rule requires a completed contract or receipt and cancellation notices with specified information. [2] Keep the version provided at signing. A later portal link can change, expire or show a document that was not available during the presentation.
Calculate the deadline carefully
The FTC explains that Saturday counts as a business day while Sundays and federal holidays do not. [1] Use the contract date and the stated cancellation date; do not rely on a salesperson’s verbal countdown. When time is short, consider qualified legal guidance immediately.
Create delivery evidence
Follow the cancellation instructions in the document and retain a signed, dated copy plus delivery proof. The FTC recommends certified mail for proof when mailing. [1] Also preserve any email or portal confirmation, but do not assume an unread text message satisfies the contract’s notice method.
Do not generalize the rule
Emergency work, requested repair visits and other listed situations can be excluded. [1] Florida law or the contract may create additional questions. This guide is a document-control checklist, not a legal conclusion that any particular solar agreement is canceled.
