Hello all, my wife's parents live up in the far north of China in a rural village. In their village the winter temperatures often fall to -30F or more. Also, since they live in the countryside having week-long power-outages are not uncommon. We want to try to supplement their heating with a little solar energy. The only problem is mass amounts of snow. Please forgive me if this is a stupid question, I live in tropical Hong Kong, would waxing the solar panels with a slick coat of car wax and placing them at an angle provide any anti-snow qualities at all?
