Can you cut flexible panels?

I’m looking at putting some panels on the top of my pop up camper. Unfortunately, it seems I can fit 2 panels quite easily, but if they were an inch smaller in each direction, I could fit four.

So, is it possible to trim the bezels around the cells down a bit?

I wouldn’t cut into the bezel, may just ruin it. Maybe try overlapping them a bit on each side. Might give you the room your needling. ?
