Electricity plays a big role in most life support and entertainment systems in a skoolie. I plan to have several possible sources of electricity, including shore power, a generator, and the bus’s alternator when we’re driving down the road. But I expect the main power source will be solar panels by Renogy. If I was able to order skoolie projects based on my interest level, I’d be hanging curtains next. But I don’t think it’s wise do any finishing work until I’m mostly done drilling holes in the ceiling and walls. And installing solar panels requires one to make holes. Thirty-two of them in my case. I watched countless YouTube videos in search of the best way to attach the panels to the roof. I was leaning toward a robust structure using C channel. It’s a good choice if you need to support a roof deck. But the solar panels weight only 14 pounds each. Renogy sells optional Z Brackets to mount its solar panels. But if I ever needed to remove a panel to replace it or fix a roof leak under it, I would have to unbolt the Z bracket from the roof, undoing and waterproofing around it. And with a finished ceiling on the inside, I don’t know how I’d re-attach the solar panel. So I designed a system using 1” wide flat steel, threaded couplers and angle iron. In the video I take you through the process step-by-step. It’s worth noting with respect to this video, and indeed all my videos, that I’m not an engineer or skilled tradesperson. I’m a lifelong tinkerer, making it all up as I go along. So please use your own judgement when considering adopting a solution shown in my (or any) YouTube videos.
