Name that mounting Clamp

Not answering your question but there are now panels available which are 2108 long (yes, 2 metres and 10 cm). These only require 4 clamps, two on each side. The manufacturer includes "mounting holes" in the frame 1300 apart as you'll notice when you study the datasheet:

Thanks Whinmoor for the info. It confirms that 56% is the ideal dimension between the mounting points. It shows 8 mounting holes @ either 1155 or 1300 - the average distance = 1228 which is 58% of the 2108 panel length.

Quick update,

MCS will be sending their independent engineer to inspect the panel mounting soon. If they agree that the mounting distances are too far apart then all the 54 panels will have to be removed then repair / replace the roof & re-fit correctly. Not looking forward to it but at least they will be safe & guaranteed. I hope my installer will be able to insist the original subcontractor funds the rework.

I'll present the engineer with lots of installation guidelines from all the panel manufacturers & clamping companies plus the industry standard calculations.

I will let you know the engineers findings one way or the other, it may help others in the same boat.

Mcs inspector been today & will send report soon.
In the meantime can anyone solve the red min / max clamp mounting distance in the image attached for a 1650 long panel.
The right hand image suggests 50mm either side of 1/4 of the module length. ie 412mm +/- 50mm ( 362mm to 462mm ) from the ends. This gives a centre distance of 726mm to 926mm.? The left hand image is beyond me, any ideas.
