The present research shows the effect of dust accumulation on the surface of photovoltaic (PV) modules, which cause losses in their output power. We got 28% of losses in output power at Madinah city during 60 days of dust accumulation. Two ways were used to study the effect of dust on the PV modules of type monocrystalline silicon: the quantitative and the qualitative approaches respectively. A model based on dust density is used to determine the losses of output PV power. We propose to add an important parameter noted dust accumulation coefficient (%/mg.cm-2), in data sheet of PV modules manufacturer. In addition, an intelligent cleaning system is proposed, using the notion of dust density, to start cleaning when an admissible value of power losses is reached. This process allows minimizing the effect of dust.
Characterization of dust accumulated on photovoltaic panels in Doha, Qatar
In this study, samples of dust naturally accumulated for various exposure times on photovoltaic (PV) panels were collected and characterized over a period of ten months in a solar test facility located in Doha, Qatar. The dust accumulation rate (DAR) over the exposure time was determined gravimetrically. The dust samples were characterized using particle size analysis, X-ray fluorescence (XRF), X-ray diffraction (XRD), and scanning electron microscopy (SEM). The cleanness index change rate (CICR), a measure of how fast the PV power output degrades due to soiling, was found to have strong negative correlation with DAR, but the CICR/DAR ratio was found to differ between winter and summer. The DAR and the mean particle size of the accumulated dust both decreased with increasing exposure time, reaching relatively steady values for longer exposure times. Calcium was found to be the most abundant element in the accumulated dust, followed by silicon, iron, magnesium and aluminum. Calcite, dolomite, and quartz were the dominant minerals in the accumulated dust, with gypsum being a minor component. Dust collected after dust-storm events had higher proportions of halite and quartz contents than non-dust-storm days, depending on the direction of the wind. Also, dust particles accumulated on PV panels appeared to agglomerate as the exposure time increased. The data provided in this paper will be useful for quantitatively determine the degree of soiling and its effect on PV performance in Qatar and regions with similar environmental conditions. The data will also be useful for the selection of soiling mitigation technologies.
Effect of The Different Types of Dust on The Performance of Photovoltaic Panels in Iraq
Journal of Advanced Research in Fluid Mechanics and Thermal Sciences, 2022
Iraq is characterized by an atmosphere that contains dust particles most of the time. In this study, a detailed investigation was conducted on the effect of dust particles of different types on the performance of the photovoltaic (PV) model. Data were collected for samples of four types of dust (chalk powder, brick powder, Sand, Cool powder) and different weights (30,60,90 and 120 g/m2) with the change in the energy loss of the PV module at four levels of solar radiation (500, 600, 700 and 800 W/m2). In this study the effect of environmental dust particles on energy loss as well as electrical efficiency was evaluated. The minimum and maximum power value of (43.58, 101.95W) respectively, was observed during dust accumulation on the photovoltaic unit. It was also noted that the efficiency and power were inversely proportional to the increase in weight and directly to the size of the dust particles.

The performance of PV systems is generally affected by the real weather conditions. In the desert climate, dust accumulation is one of the main concerns that may cause a significant deterioration of PV efficiency. In the present work, experimental investigations were carried out to understand the dust characteristics and its effect on the electrical performance of PV modules under Sharjah, UAE weather conditions. The morphology of the dust sample indicates that dust particles have different shapes and small sizes (1.61-38.40 µm). The results of the indoor experiments reveal a linear relationship between the dust density and the normalized PV power with a drop of 1.7% per g/m 2. Dust accumulation is a function of the tilt angle and it increases by 37.63%, 14.11% and 10.95% with respect to the clean module for the 0°, 25° and 45° tilted modules, respectively. Outdoor experiments showed that the soiling loss increased by 12.7% while the dust density increased by 5.44 g/m 2 for a period over 5 months. By comparing the results of indoor and outdoor experiments, it was concluded that the linear relationship is reliable and can be used to predict the soiling loss of PV systems in UAE and similar weathers conditions.
Experimental Investigations of Dust Type Effect on Photovoltaic Systems in North Region, Oman
International Journal of Scientific and Engineering Research
Solar energy advanced to occupy a significant place between the used energies of the near future. The operational principles of photovoltaic (PV) devices become more understood that led to an increase in the power conversion efficiencies of such devices. Solar cells or PV systems performance is affected by dust and dust storms highly impact the collected energy. Many studies showed that the accumulated dust reduces the performance of solar panels; however, these results were not clearly quantified. The effects of dust on the performance of solar PV panels was the primary objective of this study, where six types of dust investigated from different areas of the North region of Oman (Al-Batinah region and Muscat). The study results show that the dust of Sohar and Saham has the biggest negative impact on PV performance because of their properties. The moisture content of saham is 52.21%, Sohar is 45% as the results showed. In the other hand, the dust from the other four locations was li...
Experimental evaluation of dust composition impact on photovoltaic performance in Iraq

Photovoltaic cells are profoundly affected by the weather conditions of their erection area, and the most important of these influencing conditions is dust. This study focused on assessing the harmful effects of dust deposition on the performance of a photoelectric module operating in the weather conditions of the city of Baghdad-Iraq. The accumulated dust was collected for two months, and its components were studied. Also, the effect of the main three elements on the PV module performance was examined separately, and it was compared to naturally accumulated dust. Ascending blocks of; particulate particles (PM), calcium carbonate (CaCO3), and soil were used and the effect of each of them was evaluated on the PV module performance. The accumulation of dust causes a significant decrease in the performance of the PV module. The components of accumulated dust also play an essential role in determining the rate of reduction in the generated energy. Dust deposition increases the surface temperature of the photoelectric, which in turn increases the loss of generated energy. The study examined several types of locally available PV cleaning materials to evaluate the best ones. Cleaning the PV module by sodium solution reduced the generated energy loss when the module is contaminated with natural dust and PM, but its effect is limited on soil and CaCO3. For CaCO3 and soil, high-pressure water should be used, wiping the surface of the PV with a cloth or brush to prevent these substances from sticking to the surface of the PV.
Photovoltaic panel type influence on the performance degradation due dust accumulation
IOP Conference Series: Materials Science and Engineering, 2020
This study investigates the effect of the type of solar cell technology used on its outcomes degradation when dust accumulates on it. Therefore, in this study, practical tests were performed on the physical properties of accumulated dust in the University of Technology Campus-Iraq for a period of three months. After that, a practical study examined the effect of the type of photovoltaic unit used on the decrease in current, voltage, and energy resulting from the accumulation of this dust with specific mass fractions. The comparison was made between the Amorphous, Monocrystalline, Polycrystalline, and Organic PV modules. The accumulation of dust causes significant decreases in current and has a limited effect on the voltages of all modules studied, as a result, the electric power generated decrease from all the studied photovoltaic modules due to the accumulation of dust. The accumulation of dust had the greatest effect on the Amorphous PV cell, followed by polycrystalline, monocryst...
Effect of dust and weather conditions on photovoltaic performance in Doha, Qatar
2015 First Workshop on Smart Grid and Renewable Energy (SGRE), 2015
Photovoltaic (PV) power generation performance in desert environments is affected by surface soiling due to dust deposition. In this study, PV performance, ambient dust and weather conditions were measured continuously from June 1 through December 31, 2014 at a solar test facility in Doha, Qatar. Averaged over the seven months, the PV performance loss due to soiling was 0.0042+/-0.0080 per day for modules cleaned every sixth month, and 0.0045+/-0.0091 per day for modules cleaned every second month, in terms of a "cleanness index" based on the PV module's temperature-corrected performance factor. The daily change in a PV module's cleanness index was negatively correlated with the daily average ambient dust concentration, positively correlated with wind speed, and negatively correlated with the relative humidity. A multivariable regression model was developed to quantitatively relate the daily change in PV module cleanness index with the dust concentration, wind speed, and relative humidity. From the results of this study, it is clear that dust deposition on PV panels can cause significant loss in PV power generation in Qatar. Additional research is needed to refine the mathematical PV power generation performance and the ambient environmental variables, so as to enable accurate simulation of PV solar power plant performance based on environmental data.

The process of transfer of radiation from the shining surface of the photovoltaic module is adversely affected by the accumulation of dust carried by air. This research work is directed to investigate the effect of the dust particles accumulated on the surface of polycrystalline photovoltaic modules. In this research two polycrystalline modules were used by the string equipped with twenty (20) and out of those two modules, one was exposed for three months of summer season in natural atmosphere with regular cleaning at Quaid-e-Azam Bahawalpur Park, Pakistan. During this period, a series of systematic measurements related to different densities were performed. This study shows that a noticeable difference was seen between the different parameters of production of both clean and dirty modules. This study also provides information about percentage loss for different densities of dust. The densities of dust accumulated on the surface of the PV module for June, July and August were 0.786 ...
