Nothing’s going to last very long for tape in tension on the backside of a panel out in the sun. Guerrilla Tape, or that silicone tape manufacturers use on camper roofing these days.
or a zip tie with the screw eye on it, and a little stainless self tapper? That’s what I’d do.
I use cable ties to attach my cables to the z brackets. I haven't seen any problems on my RV. No way I would be sticking anything to the underside of the panel.

I have used plastic cable covers with adhesive backing. I got mine at Home Depot or Lowes in the electrical department. Not sure if they are UV safe most likely not. But it worked well. Never came off or fell apart in two years.
