“…If it is supposed that DDP is proportional to dust deposition rate, it may be calculated with the Under circumstances exposed in this study, the annual loss of electric energy into the grid is estimated in only 3.6%. This data is in accordance with experimental findings by other reports [15,16] and commonly used factors for estimation of life cycle assessments for PV systems [17]. As a consequence, the benefits of additional cleaning of modules could be questioned.…”

The deposition of dust on photovoltaic modules is of importance as parameter for economic analysis and life cycle assessments to evaluate this kind of technology for generation of electricity. Even though during the last two decades several photovoltaic plants were implemented, only a few studies about this issue were performed. This work tries to estimate the annual loss of generated energy caused by dust deposition on PV modules based on an experimental setup of a grid connected PV plant, monitoring of solar irradiation, onsite determination of dust deposition rate, and processing climatic data to obtain information about the frequency of rainfall occurrence. In Mexico City, air pollution with suspended particulate matter with diameter below 10 μm (PM 10) is almost permanently over 50 μg m -3 . This contamination contributed to an average dust deposition rate of 65 g m -2 d -1 on horizontal surfaces. Dust accumulation during rainless periods of more than 60 days can reduce production of PV systems up to 15%. With the capacity of natural cleaning by rainfalls, annual loss of production is estimated to be 3.6%.

“…Mejia and Kleissl (2013) showed a 7.4% loss over 4e5 months of exposure of solar panels in the Californian summer, slightly higher than our 6-month figure. These are lower than losses in Malaga, southern Spain, where 3.3% per day has been reported (Piliougine et al, 2013); rainfall in the summer months in this part of Spain is generally zero, allowing a build-up of soiling, a situation different from that obtaining in SeE Brazil. In Cyprus, where droughts can be frequent and severe, the reduction in performance after a dust episode followed by heavy rain was about 13% (Kalogirou et al, 2013).…”

“…Jiang et al [8] have studied the effect of dust on three different kinds of PV modules under controlled conditions in laboratories and have pointed out the relationship between deposition density and energy output reduction. Thus, it appears that the decreased influence of accumulated dust on the output of PV modules is significant [9][10][11][12][13][14][15]. 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.…”

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.
