Having researched this subject for quite a while now, I was debating whether it would be worth putting solar panels on the roof of my Vdub, buying a portable array or just using hook-ups whenever I needed to re-charge the leisure battery. In the end, I decided I wanted the ability to spend several days at a time at campsites that would not necessarily have hook-up facilities. So I opted for these panels from Baird:
They are not too heavy and I can store them easily in the bus when travelling. A couple of minor issues with the cables that were supplied, but otherwise seem to be very good.
I opted for 120W panels as these should easily cover our daily electricity use. Details on how to calculate this here. Fixing then up to the bus was not difficult, but entails getting some solar cable and connectors as well as some battery connectors. Details in pictures below. My California is a 2015 Beach – the wiring layout picture might be a useful reference for other Beach owners.
For security, I will padlock the panels to the bus with some cable, and to prevent any wind damage I’ll peg the units to the ground with some large tent pegs.
