It's nice to see someone doing things logically as opposed to being "rabid" about it. You seem to have learned as you go and converted when you could afford it.
You've got at least 2 different types of PE Panels in Mr Rain's video so I assume you didn't buy them all at the same time.
Too many people think they can just spend a big chuck of cash and be "totally self-sufficient".
Skills and the discipline needed to make it work can't be bought.
Hats off to you and Mr Rain.
You are correct, we started with the silver framed panels, then found better ones as we added on bit by bit. As we have done with everything, we just keep building our self-sufficient life piece by piece. It also makes for a much easier adjustment. Had I tried to do everything I do now all at the same time, I would have burned out quickly!
