The main effects of dust deposition on photoelectric efficiency are shading effect, temperature effect and corrosion effect. The surface of the photovoltaic panel is made of tempered glass with a transmittance exceeding 91%. Dust will deposit on the surface of photovoltaic modules and form a dust layer, and it will reflect and absorb light.
The accumulation of dust and aggregation on the surfaces of the PV panels cause a haze of solar irradiation and acts as a shadow; leading to increase the temperature of the PV. The temperature, in turn, reduces the efficiency and performance of PV ( Kazem et al., 2017 ).
One of the principal features of PV power degradation is dust settlement over the PV panel surface, which significantly impacts energy output over an extended period of utilization and damages the panel’s film, resulting in reduced output and a shortened lifetime [59].
Such a testing protocol would assist in the development of the Photovoltaic Soiling Index (PVSI), which is a suggested “dust coefficient” for PV devices used to correlate between the accumulation of dust on the surface of PV panels and their electrical performance in specific locations and within specific time periods.

Methodology
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.
How effective are PV cleaning systems for reducing dust accumulation?
Recent studies have suggested that PV cleaning systems are the most effective method for reducing dust accumulation, as they can reach more areas of the module and are more efficient than manual and forced air cleaning. Finally, several studies have reported trends in dust-related losses in PV modules.
Does dust accumulate on the surface of PV modules reduce electrical parameters?
The results showed that dust accumulation on the surface of the PV modules significantly reduced the electrical parameters. The tilt angles of the PV modules in Sites 1, 2, 3, 4, and 5 were 13°, 17°, 9°, 8°, and 5°, respectively, leading to reductions in maximum power of 1.3 %, 5.9 %, 20.1 %, 14 %, and 1.5 %, respectively.
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°.
