The window
No deadline
Nothing to register and nothing to confirm.
Current TOPHiKu6 residential modules carry 25 years product and 30 years performance, with no registration deadline found. Terms run from the standard start dates in the document. Keep the invoice, the delivery date and the serials with the job, and confirm the document for the exact module series installed.
Register: step by step
Capture the nameplate before anyone leaves site
Photograph the nameplate and record the serial and model. Canadian Solar asks for serial number, model, installation date, customer name, installation address, and every one of those is easier on the roof than from the office.
Open the Canadian Solar portal
Registration happens at https://www.csisolar.com/warranty/. You register this one.
Record the confirmation
Save the confirmation number and the date against the job. There is no deadline to prove, but there is a start date to prove, and that is what a claim will ask for.

What has to stay true afterwards
Registration is a moment. Conditions are permanent, and they are what actually decides the term.
Nothing has to stay true
Canadian Solar attaches no conditions to the full term in the document we read. Keep the serial, the invoice and the install date with the job and the claim file is complete.

Checked 16 August 2026
Warranty terms change and differ by country. This is a reading of the manufacturer's published document on the date shown, not legal advice, and not a substitute for the document that applies to the model you installed.
Stop chasing Canadian Solar registrations by memory
Claim Timer holds each brand's route and conditions on the equipment record, so the confirmation number lands on the job instead of in somebody's inbox.
