I have given a lot of thought to adding a solar panel to my Sterling Eccles Moonstone (2007) caravan to provide battery top up on 2-3 long weekend breaks per year where we do not have hook-up. Initially I thought about a lightweight 100Watt Semi flexible panel. These are designed to be glued down on the roof - which dont like as they are a nightmare to remove if they go faulty. I considered fixing it to the roof temporarily with suckers or ties (not mobile) but they are not designed to be portable - and when regularly flexed apparently the metal strips between the cells can fracture.
It is not practical to use a suitcase style panel at ground level as this needs turning into the sun from time to time and Security at some event sites I use is not particularly good. (I am away from the van most of the day)
I then looked at a permanent installation, between my front large roof vent and the roof extractor fan, using a ridged solar panel supported by 4 corner and 2 side UPVC blocks. A 100W panel weights about 9Kg. This would raise the centre of gravity of the van slightly. Does anyone know if the roof will adequately support such a weight in a mobile situation without weakening the roof stucture over time please?
