BTW, the OP did state possible damage on his end, so one can't jump to a QC conclusion from that.

The OP was referencing the Renogy "
semi-flexible" panels.

In my experience I find these are rather marginal quality knock offs of the Italian made Solbian panels. I have seen numerous panels come out of the the same Chinese factory with a Renogy, Shine, Grape etc. label on them
not meeting spec, right out of the box. It was not "
jump to conclusions" because I have seen, tested and measured this on numerous occasions, just as others have, and these have not been dropped..
I was merely stating what I and others have experienced with these panels and to beware of the often abhorrent QC on them..
The problem is they don't use A grade cells and they can be riddled with microcracking. If you get panels meeting spec they can actually be a
good value, but if you don't test them, then you have no way to know so you can send them back and try another...
I recommend testing any of the Chinese semi-flexible panels against spec, as best you can, and against each other to ensure they are not under performing.
