I am planning to install a polycarbonate skylight (22'x 5') at my back yard for laundry purpose. Currently, I have three AC compressors mounted to the wall at the back yard. I want to install the polycarbonate below those compressors so that the AC technician could perform the AC maintenance easily.

Can the material of polycarbonate allows loading for people to stand on top without damaging it? Appreciate if someone here could advise me and give me the best price. Thanks.
