Hey, Dan!  I thought you lived way up north in Couer D'Alene, like at about
45 degrees latitude.  Just tilt your charger so that it faces where the sun
really is and the resulting 45 degree angle should keep the snow from
collecting on it.  

Unless, of course, the snow is really deep and reaches up all the way from
the ground...
