Minimum adhesive .. ?

[Nigel Crompton]

So, a while ago whilst scrubbing Saharan sand off the roof I noticed that one corner of the solar panel was loose. Took the mounting off and gave the other 3 corners a tug - all seemed OK so I stuck the loose one

back on.

Fast forward to 2023 and I have two new 100w flexi panels to replace the the existing rigid one. "Cheese-wired" the rigid panel off with little difficulty - apart from the corner I'd re-done.
My question is just how little adhesive can (main dealers) get away with ??
What little was there need a sharp chisel to remove

Makes you wonder if it was the end of the tube and they couldn't be bothered to fetch another one!!
