Does the tilt of the panels affect fouling?

The tilt of solar panels plays a significant role in their fouling and, consequently, in the energy performance of a photovoltaic system. Studies show that modules installed flat accumulate dust, sand, pollen, and other particles more easily than those tilted at a steeper angle.

However, the angle is not the only factor: the wind direction, the frequency and intensity of precipitation, and the type of fouling material also influence the speed and type of fouling. An effective approach is to adapt the cleaning procedure to the specific configuration of each installation.

AX Solar cleaning robots automate this maintenance by adjusting the cleaning method according to the inclination and actual condition of the panels, thus ensuring optimal performance while preserving the longevity of the modules.
