It''s a different story when heavy snow accumulates, which prevents PV panels from generating power. Once the snow starts to slide, though, even if it only slightly exposes the panel, power generation is able to occur again. Heavy snowfall can present a problem when the weight of the snow places stress on a PV system''s support structure.
