摘要
光伏板在运行过程中容易降低可利用率,分析了主要因素,在给定条件下,通过统计光伏板清洗前、后发电量,绘制出光伏板清洁度与发电量增益的曲线,得出在此条件下光伏板的最佳清洗频次。此最优解在平衡成本的基础上最大限度地提升了设备利用潜力。光伏电站可根据自身所处环境,结合光伏板清洁度与发电量关系制订清洁计划,为清洗工作提供理论依据,此办法可使光伏板的经济性得到极大改善。
This paper analyzed the main reasons of that the availability factor of photovoltaic panels is easy to decrease during runtime. Under the given conditions,through a statistical analysis of the generating capacity of photovoltaic panels before and after cleaning,the relation curve between the cleanliness and the generating capacity of photovoltaic panels is provided. After that,the optimal cleaning frequency of photovoltaic panels is obtained and this helped to improve the utilization potential of equipment on the basis of controlling cost. Photovoltaic power plants can set a cleaning schedule based on their situation and the relationship between the cleanliness and the generating capacity of photovoltaic panels. This paper provided a theoretical basis for the cleaning work and improved the economic effect of photovoltaic panels.
