The reason that I suggested wire looms... This is on the top of my Airstream. I had a RV shop do the install of a 150 watt panel, as I didn't have a safe way of getting on top to do it myself. When I did a quality check on the install, I found no grommet on the hole leading the wires from the panel into the trailer, and routing of wires across a sharp edge.
The shop got to do it twice. Now there's a grommet on the hole, and a clamp holding the wires off the sharp edge.
