Looks like layer over layer. Are you planning on changing/redoing the cabinet and shelves? If so, I’d take those off first. Then check and see how far those vertical panels go across. They must be fake planks (large solid back) so it can be attached to the studs or real planks nailed/screwed to plywood or something. Also check the pegboard. Is it behind the panels? Or just butt up against it?

Also, you’ll have to unplug the electrical, unscrew the plate, and see. I bet the plate it’s screwed into the panel too.
