As the panels heat up in the sun the snow will melt off the panels and slide off your roof. Snow guards can be installed so the snow will break up while falling from the roof instead of falling in one large sheet. At best, this can labeled as an inconvenience, because roof snow removal is no walk in the park, but because the panels are installed at steeps angles and because of the surface material, snow usually slips right off the panels with no hassle. If you find that your panels are covered in snow, after a day or so those panels will heat up and they won’t be covered for long.
