摘要

通过实验和模拟仿真获得高速公路边坡光伏组件现场积灰规律以及表面积灰对光伏组件运行效率的影响规律

建立高速公路边坡光伏组件清洁周期优化模型。结果表明：边坡光伏积灰密度随暴露时间的累积而增大

但积灰速率随时间的累积逐渐降低。当积灰密度从0增长到2、4、6、8、10 g/m2时

光伏组件运行效率从21.1%分别降至17.4%、14.7%、11.2%、10.0%、8.4%。在山东省金乡县冬季28 d连续不降水的周期内

对高速公路边坡光伏组件开展1次清洁能带来0.48元/kW的最大清洁净收益。

Abstract

The laws of dust accumulation on the PV modules on highway slopes and the influence of the dust accumulation on the operating efficiency of the PV modules are obtained by experiments and simulation

as well as the optimization model of the cleaning cycle of the PV on the highway slope is established. The results show that the dust accumulation density on the PV modules on highway slopes increases with the increase over time

but the dust accumulation rate decreases with the increase over time. When the dust accumulation density increase from 0 to 2

10 g/m

the operating efficiency of the PV modules decrease from 21.1% to 17.4%

14.7%

11.2%

10.0%

8.4%

respectively. During a period of 28 days without precipitation in winter in Jinxiang County

Shandong Province

the highest net benefit of the cleaning of the PV on the highway slope is 0.48 RMB/kW by carrying out 1 cleaning operation.
