Polycarbonate is close to unbreakable, so you might have cheaper acrylic panels. I have 3mm polycarbonate that you can almost bend in two, or hit full force with a hammer without breaking.
The main cause of wind damage is wind getting into the structure. Once you get panels or doors popping off, the structure becomes weakened and susceptible to damage. You could seal all the panels into their frames with some clear silicone. This will stop wind getting in, and add more structural strength.
If the doors are loose fitting, you may need to secure these in high winds.
