Abstract

Abstract: In this paper, the research on the performance of photovoltaic modules with different sediment density was carried out under the conditions of the laboratory, and the effects of different sediment density on the open circuit voltage, short circuit current, conversion efficiency, fill factor and power of the photovoltaic module were analyzed. The research results show that the power of the accumulated sand PV module is significantly lower than that of the clean module, but with the increase of the accumulated sand density (0g / m 2 -68.3g / m 2 ), the short circuit current, output power, conversion efficiency and fill factor of the module show a downward trend. There is no significant impact on the open circuit voltage of the module compared with the clean module, and the output power of the module is reduced by 27.8%. The relative power generation rate shows a downward trend and the maximum value of the decline can reach 27.9%.
