Warranty comparison
Silfab vs Q CELLS
The same four questions asked of both: how long on parts, how long on labour, what has to be registered, and what has to stay true.

On warranty terms
Line ball
Neither asks meaningfully less than the other.
Silfab and Q CELLS land in much the same place on warranty terms, and the choice comes down to what each one needs from you rather than to the headline number.

What separates them
- Neither pays toward labour on the lines in this catalogue, so the truck roll is yours either way.
- Both carry 25 years on parts, so the parts term is not the thing that separates them.
Silfab
Checked 16 August 2026
Silfab's product warranty is 12 years from delivery, extended to 25 years when the installation, site and product details are registered through Silfab's portal within 180 days of purchase. The performance warranty runs 30 years either way. That 180 day window is the clearest real deadline in the US residential market.
Nothing has to stay true
Silfab 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.
Q CELLS
Checked 28 July 2026
The Q CELLS module warranty terms we could read run the warranty period from the end customer invoice date and mention no registration at all. Keep the invoice, because it sets the start of the term. Confirm the current document with Q CELLS if anything material rides on it.
Nothing has to stay true
Q CELLS 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.
