Can a photovoltaic power station remove snow?

Manual snow removal, which is usually done using high-pressure water guns or cleaning brushes, is one of the main methods used in many photovoltaic power stations (Gao, 2013 ). Although this method is simple and environmentally friendly, its snow removal efficiency is low.

Can snow slide easily down a photovoltaic panel?
