title: Efficiency Evaluation of Cleaning a Photovoltaic Panel Surface from Snow and Ice by Supplying Electrical Energy to Its Outputs
abstract: Energy generated by a photovoltaic panel directly depends on the amount of solar radiation falling on its surface. In the winter season, perhaps the main factor that affects a panel operation is the soiling of snow and ice on its surface. It decreases a panel’s efficiency and reduces the reliability and durability of its work. The authors reviewed the existing methods that are used to clean panels surface. Noted the great interest and attention paid by researchers to the considered problem. The
