中文摘要	通过选取不同积沙密度和沙尘粒径分别沉积在光伏组件表面,对光伏组件温度性能影响展开研究。结果表明:清洁光伏组件的背板温度高于积沙光伏组件的背板温度。当光伏组件表面的积沙密度不断增大时,光伏组件的温度呈现先下降后上升的趋势;当光伏组件表面的积沙密度小于等于35 g/m~2时,影响温度的主要因素是遮挡而造成吸收辐射能的减小;当光伏组件表面的积沙密度增大至35 g/m~2时,由遮挡而影响的温度降低幅度达到最大值,当组件表面积沙密度大于35 g/m~2,表面积沙使组件的散热性能降低,热阻增大,背板温度上升;当组件表面的沙尘完全遮挡住太阳辐射时,组件的温度不会上升,此时组件温度与环境温度相接近;当光伏组件表面积沙粒径增大时,光伏组件的温度整体呈现先下降后上升的趋势,且在粒径为0.04~0.06 mm时光伏组件的温度最低,与清洁组件相比其温度降低的最大值为6.62 ℃,在沙尘粒径为0.3~0.4 mm时光伏组件的温度是积沙组件中温度最高的,与清洁组件相比其温度降低的最大值仅为2.3 ℃,温度降低的最小值仅为0.85 ℃。
英文摘要	This paper studies the influence on the temperature performance of photovoltaic modules by analyzing dust with different sediment density and sand particle size that deposited on the surface of photovoltaic modules. The results show that the backsheet temperature of of the clean photovoltaic module is higher than that of the sedimentary photovoltaic module. When the density of the sand on the surface of the photovoltaic module is continuously increasing,the temperature of the photovoltaic module first decreases and then rises. When the surface sand density is less than or equal to 35 g/m~2,the main factor affecting the temperature is the reduction of the absorbed radiant energy due to shielding. When the sand density on the surface of the photovoltaic module increases to 35 g/m~2,it is affected by the shielding. The temperature reduction reaches the maximum value. When the sand accumulation density is greater than 35 g/m~2,the surface area of the sand reduces the heat dissipation performance of the module,the thermal resistance increases,and the temperature of the backplane increases. When the dust on the surface of the module completely shields the solar radiation,the temperature of the module will not rise. Due to heat dissipation,the temperature of the module will slowly drop to the ambient temperature. When the surface area of deposited dust on the photovoltaic module increases the overall temperature of the photovoltaic module It shows a trend of falling first and then rising. The temperature of the photovoltaic module is the lowest when the particle diameter is in the range of 0.04-0.06 mm. Compared with the clean module,the maximum temperature decrease is 6.62 ℃. When the sand particle diameter is in the range of 0.3-0.4 mm,the temperature of the photovoltaic module is the highest among the sandy modules. In comparison to the clean module,the maximum and the minimum temperature reduction is only 2.3 ℃ and 0.85 ℃,respectively.
