Snow precipitation can be accompanied by harsh weather conditions, such as strong winds that can affect your system's integrity. Wind loads can cause premature wear on PV modules and supports, with the appearance of cracks or detachment of parts.
When photovoltaic panels are covered by snow, the heat generated in the semiconductor region inside the photovoltaic module due to the energy level difference of the pn junction and the resistance of the semiconductor can be utilized as 'load' for the photovoltaic cells.
Photovoltaic panels can remove snow when the snow thickness is greater than the equivalent height and the inclination angle is greater than the required minimum inclination angle. Experimental studies have shown that the method proposed in this paper achieves this purpose for such conditions.
Therefore, installing solar panels on supports elevated enough to account for snow accumulation allows the system to continue generating energy even after heavy snowfall. There are other possibilities in case precipitation above average would require manual snow removal.
