HI all,
I just came across this thread and having done a very similar job thought that it may be useful to add photos of my panel installation. It is a 200W single panel (Allpowers) which by positioning it asymmetrically across the roof rails towards the awning side fits in nicely.
I used some aluminium strips across the roof and bonded to the panel with U extrusion end caps. It is secured by drilling through the panel and strips and use of M6 T nuts. I also used neoprene strips to pad from the roof. The finished assembly is nice and solid with no wind noise or vibration.
I created my own curly cable by winding some 12AWG 2 core cable tightly around a pole. I secured it with tape and left it in the warm sun for a couple of days, then steamed it for good measure. It held the shape nicely when I removed it and after a month or so and a bit of roof use now shows no sign of loosing the coil/shape. Cost £10.
The junction box was a bargain - quoted as being IP68 rated and 2 for £6.99 from +amazon+amazon+amazon+amazon+amazon+amazon. I removed the MC4 connectors from the panel wiring and solder joined to the curly cable inside the box.
