Dustings: Let the sun melt it off.
Snow storm: Big pole with a brush on the end.
Ice storm: Well shit...
@hi I'll have to know the answer to this question the coming winter, too...
(OTOH, I did sleep in an igloo a couple of times, and it's remarkably well-lit by the sun inside, so you'd still get some % of power even when covered)
for better or worse winters getting warmer here and snow is not staying for long
@hi
I try to trigger a roof avalanche by throwing snowballs at it. Hey, it did work (twice, partially)! It was fun, but winter production is just so "meh", even with clean panels. :-/
@hi If they are on a steep enough angle, the snow slides off as soon as any light filters through the snow and starts generating power.
The other alternative, which we use on our non-roof mounted, is to change the panels to vertical so the snow never sits on them. The reflection of light off the snow makes up for the miniscule loss of power from not being more directly aimed at the sun, plus it eliminates any and all issues with clearing them off.
