<span class="highlight">Solar</span> <span class="highlight">panel</span> wiring on Coromal poptop camper - through or around the roof?

Hi Bryce.

The solar cable I'm talking about goes from the battery compartment, under the floor by the doorway and comes up on the other side of the doorway up to the ceiling and ends in a length of rolled up cable. There is also a black switch next to the doorway to turn on and off the power from the panels. This is a standard factory fitting to save the owner the trouble I'm told.

The Coromal rooves are quite strong. Mine can support my weight walking around on it so a few solar panels or other light items should be no problem.

According to Melbourne Caravan Repairs such things are normally stuck on with Sikaflex or similar and without bolts. You just need the surface area on the mounting rails and at least 5mm of Sikaflex under them to make it work. A roof rack for a spare tyre or jerry can of fuel is definitely out of the question, though.

I've just emailed Coromal asking how they normally get the solar wiring up to the panels so stay tuned for that info.

Coromal said call a dealer. So helpful. Thanks Coromal!

Well I've finished building the frames. All I need to do is prepare the roof surface and frame surface with sandpaper and metho and then stick them on.

BTW I was mistaken about the black switch as it is actually for the external light (shows you how much I use it) but the solar cabling (I thinks it's 4.6 mm sq twin core cable) also runs through a hole just above the switch.

As for getting the solar cable up to the panels I was fortunate enough to have an air intake vent put in to keep out the dust when travelling. This is not the normal wind up air vent. Anyway, I believe I can thread the cable though the seal and out to the roof and just silicon it up. Of course that means I'll have to run the cable along the ceiling inside and make it pretty somehow. There was no room to have it wrap around the lip of the roof. It would have eventually worn through I think.
