My experience with polycarbonate panels is that the snow quickly forms a thin layer of melt water where it touches the glazing, and then the whole pile of snow slides right off. If you can hold the snow in place it will provide additional insulation, but also prevent sunlight in.
Yeah ,i have the same experience with the policarbonate, but i was thinking now that i have the bubble wrap on ,it will keep the snow a bit colder at the bottom and not melt as much.
Anyway ,i need to try this and see how it goes.
