Polycarbonate glazing panels often get blown out by strong winds so if you are in a particularly windy spot then maybe not ideal. Safety glass would be my recommendation, especially if there are likely to be young children (or wobbly older persons) in the vicinity. Expensive but worth it. Glass is also heavier and helps hold a greenhouse in place if it hasn't been attached to the ground properly. If you have a wall to attach a lean-to type to then you will benefit from the heat-retaining properties of the wall which will keep the greenhouse warmer at night.
If you go for polycarbonate due to budget constraints (they are a lot cheaper) make sure the frame is attached firmly to the ground using ground anchors or screwed down to concrete or slabs by drilling into it using masonry bit and using rawlplugs and 50mm long screws.
