“…Adotou-se nessas simulações, o coeficiente de decaimento de capacidade de geração de energia [%/dia] como componente da função, pois a literatura demonstra que há um percentual de redução da produção diária de eletricidade em módulos fotovoltaicos sujos, comparado a limpos (Fraga et al, 2018;Junior, Cruz and Amaral, 2018). Em revisões recentes e completas da literatura, as perdas devido à sujeira variam de cerca de 6% em um período de 1 dia, podendo chegar a mais de 50% em períodos superiores a 6 meses, dependendo do material de fabricação dos módulos fotovoltaicos e das localidades em que estão instalados (Mani and Pillai, 2010;Adinoyi and Said, 2013;Sarver, Al-Qaraghuli and Kazmerski, 2013;Jones et al, 2016;Saidan et al, 2016).…”

O acúmulo superficial de materiais particulados, provenientes da poluição atmosférica, em módulos fotovoltaicos atenua a capacidade de geração de energia elétrica, sendo inevitável a limpeza desses módulos. A redução da capacidade de geração diminui as receitas com geração de energia elétrica, e as limpezas têm custos associados. Por esse motivo, este trabalho desenvolve uma equação de estimativa de receita líquida considerando esses dois fatores citados, envolvendo o intervalo de tempo entre as limpezas. A equação de receita líquida foi resolvida pelo método de Newton e pelo método da Secante - com o propósito de encontrar a frequência ótima de limpeza que maximize a receita líquida dessa operação. Os resultados computacionais mostram que a não otimização pode levar a situações operacionais com receita líquida reduzida.

It has been a key issue for photovoltaic (PV) cells to survive under mechanical impacts by tiny dust. In this paper, the performance degradation and the damage behavior of PV cells subjected to massive dust impact are investigated using laser-shock driven particle impact experiments and mechanical modeling. The results show that the light-electricity conversion efficiency of the PV cells decreases with increasing the impact velocity and the particles’ number density. It drops from 26.7 to 3.9% with increasing the impact velocity from 40 to 185 m/s and the particles’ number densities from 35 to 150/mm2, showing a reduction up to 85.7% when being compared with the intact ones with the light-electricity conversion efficiency of 27.2%. A damage-induced conversion efficiency degradation (DCED) model is developed and validated by experiments, providing an effective method in predicting the performance degradation of PV cells under various dust impact conditions. Moreover, three damage modes, including damaged conducting grid lines, fractured PV cell surfaces, and the bending effects after impact are observed, and the corresponding strength of each mode is quantified by different mechanical theories.

“…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.
