The panels in this video have a plywood backing with 2×4 frame, the plywood and OSB was covered with fiberglass for a moisture proof backing, I am trying different materials to see how long they last, the cost of building theses has been really cheep for me, I use materials leftover from my work projects these panels are not meant for roof tops keep them close to the ground for inspection. The workmanship is not so good, I like to build things fast so I can move onto other stuff, most important thing is that they work that’s all i care about.
