“…As commented, the main consequence of soiling is the reduction of the energy generated by PV modules [28]. The amount of energy losses due to soiling shows a strong correlation with the accumulated dust density [76][77][78][79] and with some properties of dust, such as chemical composition and size distribution [80]. In this sense, some studies show that PV efficiency is being affected more by finer particles in comparison with rough particles [81].…”

The exponential growth of global capacity along with a reduction in manufacturing costs in the last two decades has caused photovoltaic (PV) energy technology to reach a high maturity level. As a consequence, currently, researchers from all over the world are making great efforts to analyse how different types of degradation impact this technology. This study provides a detailed review of the impact of different optical degradation mechanisms, which mainly affect the transmittance of the top-sheet encapsulant, on the spectral response of the PV modules. The evaluation of the impact on the spectral performance of PV modules is evaluated by considering the variations of the short-circuit current since this is the most widely used parameter to study the spectral impact in outdoors. Some of the most common types of optical degradation affecting the performance of PV modules worldwide, such as discoloration, delamination, aging and soiling have been addressed. Due to the widely documented impact of soiling on the spectral response of modules, this mechanism has been specially highlighted in this study. On the other hand, most of the publications analysed in this review report optical degradation in PV modules with polymeric encapsulant materials. Furthermore, an innovative procedure to quantify the spectral impact of degradation on PV modules is presented. This has been used to analyse the impact of two particular cases of degradation due to soiling and discoloration on the spectral response of different PV technologies.

“…Therefore, the dust deposition on the PV module surface has always been a research hotspot. For example, Guan et al 13 found that dust accumulation decreased the transmittance of the glass plates on top of the module by 20% after 8 days of outdoor exposure and also reduced the working temperature of PV modules. Jiang et al 14 investigated the influence of dust accumulation on different types of PV module, and the results confirmed that dust accumulation would affect the output current and output voltage of PV modules significantly.…”

This study proposes a methodology to optimize photovoltaic (PV) module tilt angle based on regional clustering and cost evaluation. The factors that affect the power generation of PV module have significant geographical differences and coupling characteristics, and the impact of each influencing factor varies at different installation parameters. Initially, this paper performs clustering analysis on the geographical regions of mainland China to obtain 10 geographic regional classifications based on the consistency of impact degree of influencing factors. A PV module power generation prediction model is constructed by considering the influence of environmental and installation factors comprehensively and then the optimum tilt angle is further obtained. Application results in Wuhan City verifies the accuracy and validity of the proposed model with a relative root mean square error (% RMSE) and mean absolute percentage error (MAPE) of 1.9% and 1.66%, respectively. Subsequently, the model is applied to the power generation prediction of PV module in Hangzhou City.The results indicate that the optimum angle of the PV module is affected by the cleaning cycle. To investigate the relationship between the cleaning cycle and the optimum tilt angle, a novel cost evaluation model that considers the power loss and cleaning costs is proposed. Based on this proposed model, the optimum combination of cleaning cycle and tilt angle in Hangzhou City, namely, 15 days and 22 , is determined. The results are suitable for all the regions that belong to the same regional category with Hangzhou City, Zhejiang Province. The model and analysis method given in this research can provide theoretical support for determining the optimum tilt angle and cleaning cycle of PV module in different clustering regions.

“…An extensive review performed by the authors on studies concerning effects of dust deposition on PV modules, shows that researchers evaluated the reduction in energy generation by PV modules as a function of their inclination angles, time of exposure to atmosphere, and location of installation. Only a few of these studies characterized PM by stating the particle diameter, or by a generic definition, like 'ash ', 'soil', and 'sand', etc., or based on the PV generator location, like 'desert', 'next to volcano', etc., making unfeasible their application in other locations (Abderrezek & Fathi, 2017;Ali et al, 2017;Bergin, et al, 2017;Fountoukis, Figgis, Ackermann, & Ayoub, 2018;Fraga, Campos, Almeida, Fonseca, & Lins, 2018;Gholami, Khazaee, Eslami, Zandi, & Akram, 2018;Guan, Zhang, Xiao, Zhou, & Yan, 2017;Klugmann-Radziemska, 2015;Paudyal & Shakya, 2016;Ramli et al, 2016;Saidan, Albaali, Alasis, & Kaldellis, 2016;Styszko et al, 2019;Tanesab, Parlevliet, Whale, & Urmee, 2015, 2017Tripathi, Aruna, & Murthy, 2017).…”

Performance of photovoltaic generators under superficial dust deposition on their modules derived from anthropogenic activities

et al. 2020

View full text Add to dashboard Cite

Performance of photovoltaic generators is affected by, among other factors, surface dust deposition on photovoltaic modules, which causes uniform soft shading, reducing the solar radiation reaching photovoltaic cells. Several researches have demonstrated this effect through studies in specific localities. As deposition of particulate matter varies according to locality, these results cannot be generalized or used in other places, since these studies do not characterize their local dust. Considering these research opportunities, this paper evaluates the deposition effects on photovoltaic modules by different types of dust from anthropogenic activities recurrent in urban areas, a typical situation of distributed microgeneration. Particulate matter of iron ore, building construction, quarry, and mineral coal are characterized morphologically and dimensionally. Then, their effects on photovoltaic module performance are analyzed under different deposition densities according to typical urban deposition rates. The results show that the different dust materials studied attenuate the power generation capacity to different extents, and superficial dust density of the particulate matter also produces different effects. These results can be used in performance and economic feasibility analyzes of photovoltaic generators in different locations with similar pollution characteristics.
