“…In addition to directly decreasing the intensity of solar irradiation, accumulated dust can have a negative effect on solar mirrors, which is especially so in concentrating solar power plants (CSPs) rather than PV modules. The first reason for this negative effect is the direct damage of the deposition process by airborne dust particles [16][17][18]. Karim et al reported that solar mirror surface wear depends on the properties of the sand particles, such as diameter shape, hardness, and density [19].…”

This paper reports an experimental investigation of the dust particle deposition process on solar photovoltaic (PV) modules with different surface temperatures by a heating plate to illustrate the effect of the temperature difference (thermophoresis) between the module surface and the surrounding air on the dust accumulation process under different operating temperatures. In general, if the temperature of PV modules is increased, the energy conversion efficiency of the modules is decreased. However, in this study, it is firstly found that higher PV module surface temperature differences result in a higher energy output compared with those modules with lower temperature differences because of a reduced accumulation of dust particles. The measured deposition densities of dust particles were found to range from 0.54 g/m 2 to 0.85 g/m 2 under the range of experimental conditions and the output power ratios were found to increase from 0.861 to 0.965 with the increase in the temperature difference from 0 to 50 • C. The PV module with a higher temperature difference experiences a lower dust density because of the effect of the thermophoresis force arising from the temperature gradient between the module surface and its surrounding air. In addition, dust particles have a significant impact on the short circuit current, as well as the output power. However, the influence of particles on open circuit voltage can be negligible.

“…Asl-Soleimami et al [8] reported that the energy output of solar module was reduced by 60% and recommended 30 tilt angle as the optimum for grid connected applications in Tehran, Iran. Simulated sand storms to study its effect on PV module efficiency have also been investigated [9,10]. Ibrahim [11] reported that there was decrease in the solar cell parameters of a solar cell due to combined effect of shadow and dust.…”

a b s t r a c tThere is a great potential for solar power utilization in the Eastern part of Saudi Arabia by employing solar photovoltaic (PV) modules. Dust accumulation on the surface of solar PV modules, mirrors, reflectors and other solar collectors is of great concern due to occasional to frequent dust storm in the gulf region. The performances of such devices are significantly affected by dust accumulation. This paper presents the result of a study on the effect of dust accumulation on the power output of solar PV modules in the Eastern province of Saudi Arabia. The study indicates that power decrease by as much as 50% can be experienced for solar PV modules that are left unclean for a period of over six months. Solar tracker improves power output and helps reduce dust accumulation effect by 50% at off-peak time.
