Off Grid On a budget

[NorthernRaider]

On the wind farms I used to be involved in quite a few of the crews and support staff had solar powered testing gear and panels on their van roofs (not permenent fixtures) . I noted that some were secured with chains or steel wire and cable clamps, but most had rubber exhaust mounting rings / hangers (often the Transit van figure 8 type hangers) in the line some place so vibrations from the equipment or vehicles did not damage the panels, others used shock cord or even bungy straps dunno if similar insulation is needed for boats but I thought I better mention it.
