Good morning everyone. Its another beautiful sunny bacon and egg day here on the GC. I spent half of yesty on the roof of the Winny trying to figure out how much solar of what sized panels I can get up there. There isn't much space for big panels, maybe a few of a smaller size, perhaps. You can't glue anything to the rubber roof, so it's kinda interesting finding something of substance to screw support rails to.
Enjoy your b&e Bernie.
Well be off to watch the young gkid play footy soon. It's down on the Tweed Coast today.
Safe travels everybody.
Unless you are going to use the mega expensive semi flexible panels, forget about them. The heat causes the glue that holds backing sheet on to melt, working its way between the module tabs and the foil strip grid matrix that links the modules together in series ..... one lost connection and the panel is reduced to half voltage and useless.
Along each side of the roof there is an aluminium square section that makes up the frame of the motorhome. 50mm square section, welded to 3mm thick pieces of aluminium glued and screwed down onto that aluminium frame, that makes the base to weld the rails, add cross sections to a sit the panels on to bolt them down using U shaped pieces of 3mm plate that lip over the edge of the panel and lip under the 50mm square section. A 6mm stainless bolt into a rivnut will hold the panel in place.
Alternatively, lengths of solar panel racking laid wide side down to act as the cross pieces, bolted to the outside 50mm rails, then use solar panel clamps to secure the panels ......
Let me know which way works best, so I can do my roof when we get back to Mannum
