“…The cost of cleaning PV systems is largely determined by how frequently they are cleaned and by the economies of removing dirt from them. Studies have shown that automated cleaning of solar panels in regions with less dust instead of with natural methods cannot be economically advantageous [35] . Cleaning cost is calculated by considering capital cost and equipment lifespan and operational expenses (such as electricity, water, and labor).…”

“…Deran Black, a 70-day experiment with no rainfall shows the density of dust was 6.0986 g/m, which causes the reduction of power output by 21.47%. [64] Furthermore, in an experiment in Bangalore, India shows that the seasonal change also effects the efficiency of solar modules. In summer, the SPV modules attain maximum efficiency (ηmax) at Tmod of 45 °C, but in winter, it is at 55 °C.…”

In this present era, solar modules have become a popular energy conducting element. Thus, Dhaka city is not behind in this sector as it can be seen in every building's rooftop containing PV modules. However, Dhaka city is so polluted and therefore it can be seen that PV modules become dusty quickly. It is a major concern in the Middle east and there is energy loss for this reason. The purpose of this study is to compare the output between two PV modules, where one is a dusty module and another is a clean module. Moreover, in this study how dust particles affect the module at different altitudes is another concern. Here the dust particles on the modules store heat from the sun and this affects the output, also affects the short circuit current when dust particles make shadows in the module. Two modules were checked properly in indoor conditions before conducting the outdoor experiment to know the condition of those and to get the PV graph. After that outdoor experiment was conducted on a regular basis to get the continuous data and finally the comparison graph shows the results and effects, how dust affects the module's power output. Empirical method was used to calculate the solar irradiance and finally, solar incident energy was calculated from that.

“…Dust particles in desert regions are primarily made of minerals (sand, quartz, silica, etc.) (Middleton, 2017;Chen et al, 2020;Fan et al, 2021). The stone crushing sector supplying construction materials is crucial for both employment and the economy in developing countries.…”

The purpose of this study is to investigate the potential of airborne particulate matter (PM10 and PM2.5) and its impact on the performance of the photovoltaic (PV) system installed in the Sargodha region, being affected by the crushing activities in the hills. More than 100 stone crushers are operating in this region. Four stations within this region are selected for taking samples during the summer and winter seasons. Glass–fiber papers are used as a collection medium for particulate matter (PM) in a high-volume sampler. The concentration of PM is found above the permissible limit at all selected sites. The chemical composition, concentration, and the formation of particulate matter (PM10 and PM2.5) layers on the surface of the photovoltaic module varies significantly depending on the site’s location and time. The accumulation of PM layers on the PV module surface is one of the operating environmental factors that cause significant reduction in PV system performance. Consequently, it leads to power loss, reduction of service life, and increase in module temperature. For the PV system’s performance analysis, two PV systems are installed at the site, having higher PM concentration. One system is cleaned regularly, while the other remains dusty. The data of both PV systems are measured and compared for 4 months (2 months for the summer season and 2 months for the winter season). It is found that when the level of suspended particulate matter (PM10 and PM2.5) increases, the energy generation of the dusty PV system (compared to the cleaned one) is reduced by 7.48% in May, 7.342% in June, 10.68% in December, and 8.03% in January. Based on the obtained results, it is recommended that the negative impact of PM on the performance of the PV system should be considered carefully during the decision-making process of setting solar energy generation targets in the regions with a high level of particulate matter.
