6 FAQs about [Dust at the bottom of the photovoltaic panel]

What causes dust accumulation on PV panels?

Fig. 1. Dust accumulation on PV panels. Dust is a natural phenomenon that occurs when the level of a windstorm suddenly increases. This phenomenon results in a sharp difference in the atmospheric pressure system for both summer and winter (Usov, 1991). The intensity of the dust increases as wind speed increases and the sun’s surface warms.

Does dust accumulation affect the thermal performance of photovoltaic (PV) systems?

The impact of dust accumulation on the thermal performance of photovoltaic (PV) systems primarily manifests in the alteration of PV module temperature.

Does dust affect the electrical productivity of PV panels?

Conclusions The electrical productivity of PV is seriously affected by the accumulation of dust on their surface.

How does dust affect photovoltaic power generation?

Photovoltaic (PV) power generation has become one of the key technologies to reach energy-saving and carbon reduction targets. However, dust accumulation will significantly affect the electrical, optical, and thermal performance of PV panels and cause some energy loss.

What is the distribution and density of dust on PV panel?

According to the distribution and density of dust on PV panel, the light diffuses uniformly or non-uniformly. In the case of uniform repartition of dust, a diffused light is obtained. Otherwise, when dust is randomly distributed, several points of shadows are observed underneath of glazing and on PV cell.

Does dust settle on PV panels?

In regions with distinct seasons, the rate at which dust settles on PV modules can vary. For example, during dry and windy seasons, dust accumulation tends to be higher, while rainy seasons may lead to cleaner panels.
