You can use an inexpensive piece of plywood from your local hardware store for this purpose.
Mount flexible solar panel on truck roof.
Solar cable glands bridge the gap between the roof and the interior of your van.
Cover all of the foot that will contact the roof with 3m tape.
It would be safer to have someone help you to lift the solar panels up and onto the truck camper s roof.
Connect the cables to the solar panel.
While this is less flexible than thin film solar it s well suited for a lot of applications where you want the solar panel to conform to a curved surface such as the roof of an rv.
Both cone connector sizes are available at big box hardware stores.
They look identical so you need to mark which one is hot and which one is ground on part of the cables that is not under the panel because once you stick it on the roof you won t be able to check.
I was by myself and used a rope.
Mounting flexible panels to your roof can be done in one of two ways.
You need to ensure the bolts are running through something fixed and solid not just the thin plywood and aluminum roof.
This means that you ll need to create four holes in the rv s roof which also means a higher risk for leaks.
By using butyl tape underneath the panel and by using either dicor or eternabond tape to seal the edges on the panel or by using butyl tape and screws in a traditional manner most panels have four to six grommets for mounting to the roof of your camper.
With an adjustable tilt mount you can install solar panels with or without a z bracket.
A solar panel is held in place with four bolts.
Plus these cells can be made of the same silicon as conventional panels including high efficiency monocrystalline gaining the benefit of economies of scale.
Adjustable tilt mounts can get you better efficiency on the roof or work as a stand if you are using portable panels.
Installing the solar panels is done by using unistrut cone connectors 1 4 inch or 3 8 inch to attach to the slotted steel l brackets.
