Just put a 200w panel on my Coromal. Put it to the back as I wanted to keep as much weight off the drawbar, as I had also put in a second battery (which is in the front). The Coromal Element has a black insert around the edge of the roof. I took one wire under each side of the black insert and then both to the controller next to the batteries. Had read that it is best to have the controller as close as possible to the batteries rather than near the panel and have a long run after the controller to the battery.
I also have a portable 120w panel which I can plug into an Anderson plug which is on the drawbar.
Trust this assists.
