Here we go again, we got ~10" of the white stuff, and the temps have been in the high 20'sduringthe day, and into the single numbers at night.
Noticed that the two left most arrays that are above a cathedral ceiling (think more heat loss), have nicely cleared them self, while the larger array on the right which is over the unheated attic, has hardly cleared it self at all.
Looks like the ambient temp + a bit of heat can make a huge difference in the self clearing of the panels.
Bet if I made some solar air heaters that were vertical at the base of the PV arrays, that the rising hot air could really help get the snow melting going. Would just dump the heat in the summer. May rig up a quick test if I can find some appropriate material
