Does dust pollution affect the performance of PV panels?

Characteristics of dust particles and depositions have a significant impact on the performance of PV panels. In this regard, Kazem et al. have provided a comprehensive review of the dust characteristics of six dust pollutants and cleaning methodologies impact on the technical and economic aspects of cleaning (Kalogirou 2013 ).

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.

Do solar PV modules accumulate dust particles in urban air polluted areas?

In this work, an experimental investigation was carried out to measure natural dust particle accumulation on the front surface of PV modules in the urban air polluted area under various environmental conditions. Field experiments were performed on the 14 panels tilted at angles 15° or 35°.

Do dust particles settle on PV panels if wind speed is low?

In a study by Zhang et al. , the flow field around PV panels and the movement of dust particles in the wind were simulated using CFD (Computational Fluid Dynamics) combined with DEM (Discrete Element Method). Their findings confirmed that dust particles with a size of 10 µm can easily settle on PV panels when the wind speed is low.

Does atmospheric dust affect solar panels' electrical performance?

The deposition of atmospheric dust on the PV module surfaces can lead to significant losses in the electrical performance of solar panels. Numerous outdoor and indoor experimental studies have been carried out to investigate and simulate the dust impact on the electrical parameters of PV panels, as summarized in Table 4. Table 4.

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.
