The short answer: Missouri homeowners can cancel a contract personally solicited and presented in the home within three business days, and Missouri excludes Saturdays, Sundays and legal holidays from that count; see the Missouri Attorney General. The seller must refund payments within ten days, and if it doesn’t ask for goods back within 20 days, you can keep them. The Missouri Merchandising Practices Act covers deceptive sales.
Key takeaways
- Three business days, excluding Saturdays, Sundays and holidays.
- Refunds are due within ten days.
- Goods not reclaimed within 20 days may be kept.
- The Merchandising Practices Act covers deceptive sales.

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.
