I've heard photovoltaic panels need to be washed 4 times a year to prevent dust and residue from lowering the efficiency of the solar panel. (The 4 times was in reference to a large scale grid in a desert setting). How often would you ideally want to wash a personal unit? And how much can buildup really affect efficiency?
