The reason why dust falls on photovoltaic panels

Dust blocks sun rays from reaching the surface of the PV panel (based on density, particle size, and composition) and reduces radiation [8].

Dust factors include dust size, dust type, Airborne dust concentration, and dust charged condition. PV module factors include installation method, tilt angle, orientation, and surface material. In order to determine the principles of these influencing factors, several scholars have conducted studies [4] , [18] , [19] , [20] , [21] , [62] .

Dust accumulation of 20 g/m 2 on a PV panel reduces short circuit current, open circuit voltage and efficiency by 15–21%, 2–6% and 15–35% respectively. This work reviews, elaborates and summarizes the effects of dust on solar panel efficiency and the factors governing dust deposition on PV panel.

This study provides a comprehensive review of 278 articles focused on the impact of dust on PV panels’ performance along with other associated environmental factors, such as temperature, humidity, and wind speed.

Dust accumulation on the PV panels is an area of growing concern for the reliability of solar panels; dust mitigation of solar photovoltaics is a main aspect of maintenance required for enhanced and longer yield performance of PV panels. Wind sweeps dust and dirt onto the solar panel surface, causing the dust to cover the entire panel, which .

6 FAQs about [The reason why dust falls on photovoltaic panels]

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.

Why is dust accumulating on PV systems a problem?

Dust accumulation on PV systems presents a notable challenge for the solar industry. Dust can reduce the PV efficiency, leading to decreased electricity generation and an overall decrease in performance. Fortunately, there are a number of materials that can be used to prevent dust from accumulating on PV modules.

Does dust affect the performance of solar panels?

The effect of dust accumulation on the surface of the PV panel is being given much scrutiny nowadays, as it can dramatically decrease the energy production of solar modules [ 25 ]. The objective of this research is to emphasize the impact of dust on the performance of PV panels installed in the MENA and the Far East regions.

How does dust affect PV panel performance?

Dust is scattering in the atmosphere and it is very difficult and likely impossible to control this phenomenon. In addition to that, dust also can settle anywhere, depending on various factors. Dust accumulation on PV panel's surface determines its extent of performance degradation and is influenced by several factors. 4.1. Dust properties

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 deposition affect solar PV panel efficiency?

Density of dust deposition on a panel surface depends on dust properties, environment, weather, module properties and its installation design. Appropriate countermeasures as proposed earlier should be taken to eliminate or reduce the effect of dust on solar PV panel efficiency.
