摘要
光伏发电已成为全球重要的可再生能源利用形式,然而光伏组件表面的积尘严重影响了其输出功率及使用寿命。通过分析光伏组件表面的积尘量对光伏组件输出功率的影响,计算了定期清洁积尘可增加的光伏电站年发电量及收益,并指出了自动行走类清洁机器人是大型地面光伏电站清洁设备的发展方向。
PV power generation has become an important form of renewable energy utilization in the world.However,dust accumulation of PV modules surface seriously affects its output power and service life.This paper analyzes the influence of dust accumulation of PV modules surface on the output power.The calculation results of annual power generation and benefits that can be increased by regular cleaning of dust accumulation are given,and the potential of self-propelled cleaning robots as cleaning equipment for large-scale ground PV power station is pointed out.
