Few pounds of weight on semi-rigid layer of adhesive, when placed on a slope, would attempt to slide down. In some places it can be 115F in the shade, can only imagine the actual temperature of the roof. Summer in the South turns unused caulk in the tube into liquid permanently, flexible plastic becomes brittle and crumbles like potato chips, bungee cords fall apart.
I agree on some of the statement. I live in Fla. and the sun can really be tough on materials, but I have used a vinyl roll up P/U bed cover for over 10 years before I replaced it due to it looking bad and getting cracks in the edges....even though it still kept the water out.
UV resistant materials have increased the life of many products, and glues have improved also. I don't know about the stuff the OP used to adhere the solar panel, I'm too lazy to google it.
Eternabond tape seems to hold up well in our heat, so maybe that stuff he used on the panel will hold up also. Even with the downward slope of the front cap.
