Clear corrugated fiberglass set up as a lean-to? With maybe an angle melted into the part that touches the ground so that the low end stands up a little higher?
>> stand up to wind during storms
You could bury one edge 12" deep and park some stones on that end. However, I fear that even if you bolt the high end to concrete pillars or 4x4s, a big flat sheet will act like an airplane wing in high winds. Not a good idea unless they can be cut into smaller sheets and really anchored solidly.
You don't want to see a 4x8 foot fiberglass sheet flying at your living room window with a few 4x4 posts dangling from it.
