Does anyone know of any literature that addresses snow loads and solar panels? Every time I confront the manufacturer of the panels they said they don't increase the snow load on the roof. It drives me crazy that this is never really addressed. Attached is a sample photo of a system my client wants to put on his roof. I find it hard to believe this type of system will not attract more snow because it would act like a "cheese grater". Not to mention this thing looks like it would put some concentrated loads on the roof.
