Obviously output is much reduced. I think snow will slide off the
panels very easily especially as air can circulate beneath them.

If it is cold when the snow falls heavily, it will quickly seal the air
gaps at the top & sides of the panel; *and unless the top surface is
treated in some way, snow will settle on it without difficulty.

It's treated. I have problems with masses of snow slidng off my roof
anyway. The PV panels are much smoother than the slates.
