What about a fleet of automated drones/machines which clean the panels by blowing air? I don't know, but it seems like physically scrubbing the panels would take more machinery (heavier), more moving parts (break down more easily), and the scrubs themselves would have to get replaced & careful not to be abrasive (not sure how much the panels "care" about it though). These "dusters" could run off the excess power too. I read somewhere else in this thread that one problem was the solar park would occasionally over-produce - maybe the fleet works whenever there is an overproduction, or after a certain amount of time has passed (we _must_ clean them now and can't wait until the next time of overproduction).
