Not really except that one panel I put on my car. I am look for tutorials on using PV(T?) as roofing though. I hope to start building fully offgrid small cabin/house by next summer.

In what scale? I installed a solar system on our land for pumping water autonomously and plan a larger system for our home to DIY

Yes I’m still figuring out the indoor wiring for our 13kW system for the house. We have a few panels on our travel van with a basic 12v system to run a few freezers, lights, fans, etc The key is your battery storage, and where a lot of your money will go

Questions?
