Like many, I've been researching this for a while. I've read reviews, I've slogged through some engineering papers, I've watched YouTube reviews, etc. For my needs (Full-time living), I'll be going with rigid panels. They produce more energy per unit area (costs less and smaller for the same output) they're generally rated for survival through storms.
Flexible panels can be good enough for your needs, but there are some caveats. One of the biggest ones is heat, as has been pointed out. If you do want flexible ones, and you want them to last, I recommend getting some corrugated plastic sheeting (Can be purchased, but is often free for the taking the day after a candidate loses an election) and cutting it to fit between the panel and the roof. The corrugation gives a little air flow to help keep things cooler.
For reference, see
I would just recommend NOT using both loctite and lock washers. Pick one.
