Can photovoltaic panels reduce dust accumulation?

Scientific Reports 15, Article number: 1582 (2025) Cite this article Optimizing the installation parameters of photovoltaic panels in a photovoltaic array to reduce dust accumulation, thereby enhancing their power generation, is a crucial research topic in the construction of solar power stations in desert regions.

Why do PV panels have a higher wind speed?

This phenomenon may be attributed to the decreasing influence of the ground boundary layer on the flow field around the panels as the installation height increases, resulting in a relative increase in wind speed across each panel. Particle size distribution on PV panel at different installation heights.

Does tilt angle affect particle size distribution in a photovoltaic array?

Utilizing a series of wind tunnel experiments on a photovoltaic array comprising four equally sized panels, this study assessed how variations in tilt angle, mounting height, spacing, and incoming flow direction influence both the accumulation mass of dust and the particle size distribution in a photovoltaic array.

Why do PV panels have a decreasing particle size?

Moreover, as the installation spacing between the PV panels increases, the particle size on the surface of each panel shows a decreasing trend. This trend may be attributed to the diminishing disturbance of the flow field caused by the front panels on the rear panels as the spacing increases.
