|Is that my thumb in the picture?!|
When we returned from southern Ontario, the panels seemed to have partially melted and then re-froze. That was much more annoying and difficult to clear than just regular fluffy snow would have been.
I could sweep off most of it, but then had to rely on a sunny day to melt the remainder. It's really surprising how even at twenty below, full sun can melt snow and ice on a black background!
Now, if only I could find a way to harness the power lost in that gap between Sweep Pmax and Output Power... Lithium batteries would go a long way in that department! Maybe by the time these old lead-acid ones are ready to be put out to pasture, the lithium technology will be evolved enough to make it palatable.
