Isn’t rain enough to clean photovoltaic panels?

Many people wonder if rain is enough to clean photovoltaic panels. While rain has a temporary positive effect by removing some dust and light particles, it is no substitute for a thorough cleaning.

Like your car’s windshield, rain alone does not provide the mechanical action needed to loosen even the most stubborn deposits or sand cemented by dew and fine dust. Studies on photovoltaic production show that the effectiveness of rain as a cleaning agent remains limited, and that persistent soiling can significantly reduce panel yield.

AX Solar’s cleaning robots combine mechanical action with precise washing, ensuring that even the most stubborn dirt is removed, thus ensuring maximum yield and a longer lifespan for your photovoltaic installations.
