One of the most important aspects of mounting sola panels on a roof of a caravan or similar is that you leave at least 30 mm spacing between the panel and the roof to allow the panel have an air flow under the panel. If you do not do this the panel will get overheated and the panel will be derated by as much as 20 to 30 percent. If you get the right mounting brackets this aspect will be overcome. As mentioned Jay Car sell the brackets you need.
Hope that helps

I used 50x50 aluminium angle 180mm long. I used 3 lengths each side of a 95W panel. I secured the angle to the solar panel with galvanised self tapping screws 2 per bracket. The brackets were fitted to the solar panel so that there was a air gap beneath the panel when it was attached to the caravan roof. After fixing the brackets to the panels, I put the panels on the roof in the position that they will end up in. I then marked where the brackets would sit on the roof and removed the panels and thoroughly cleaned the brackets footprint. I then put a very generous amount of Sikaflex 11FC. This type of product is a constructional adhesive and wont let go. 2 years later and all 5 panels are still on the roof. No need to drill holes in the roof. You can make the aluminium brackets the length of the solar panel if you wish but I didn't feel that it was necessary. The van was wired for solar from the manufacturer from the roof into the front boot.
I hope this helps.

I got my panels and all the mounts cables and regulator came with the kit, The mounts are plastic stuff and are glued to the roof with sikaflex product, seem to be holding very well and no holes in the roof to leak.
