    It just snowed up here in Arlington, Washington A.C.  and we were
    just starting to melt some snow<br>
    on a couple of modules on our roof just now with one of our charge
    controllers here in the lab.<br>
    <br>
    This feature is not yet in the Classic, BUT, check out this
    experiment that I did about 3 years ago<br>
    in my front yard with an animated gif time lapse.<br>
    <br>
    One module is being powered and the other is not powered, just
    sitting there for comparison.<br>
    These are KC125s.<br>
    <br>
    The time involved here was about 3 hours and took about 1 kW-hour of
    energy but gives you<br>
    an idea of what may be done with this idea.  One thing not in our
    favor here is that the module<br>
    that is being powered is resting on the ground, in the snow, which
    would significantly<br>
    hinder snow melting I would think rather than being properly
    mounted.<br>
    <br>
    Oh what fun it is to melt some PV snow tonight !<br>

                      the possibility of “reversing” the current in a
                      solar module to
                      increase the cell temp enough to shed ice/rime.
                       To follow-up, has anybody
                      been successful at this?  I am guessing, if so, it
                      would entail, removal
                      of diodes, increasing PV and battery capacity and
                      some way to sense the ice at
                      the very least. . . It sounds good in theory, but
