Snow on the Solar Panels

 Starting in mid January we had a snow storm a week for three weeks.  In addition to shoveling the snow off the decks, sidewalks and driveway, I clean it off the solar panels.  It takes about an hour using a 16 foot long swimming pool brush to sweep off the snow.  The three sets of panels include solar electric, solar water heating and a small off grid electric system.  If I wait for mother nature to clean the panels, I could be waiting a week and during that time no solar production.
