I live in Massachusetts, and have 37 250 watt panels. Snow isn't an issue. The panels generate a little bit of resistive heat, which means snow typically doesn't stick. If it's snowing so heavy, and is so cold that the panels do get covered with snow, the snow melts and slides off within an hour or so. In July my panels make 1300 kwh and in December and January they make 300 kwh, mostly because of the angle of the sun and the length of the time above the horizon. I also have significant southern tree cover, so my production is not optimal for my area.
