In reply to MG:
Based on no expertise other than erecting the odd greenhouse under Mrs Ridge's supervision, I think there might be a couple of issues:
1. Glass adds a lot of weight to the structure, so if using all acrylic you might need to beef up the ground anchors. I also suspect it adds s fair bit of rigidity to the structure.
2. Acylic, depending on thickness, probably flexes a bit when wind load is applied. If that's enough to pop the clips you'll lose the panel. If that happens in high winds the other panels tend then to blow out as the greenhouse pressurises inside.
