摘要
在我国西北部尘沙影响区域,冬春季沙尘天气对于光伏组件的发电性能影响较大。本文以西安地区屋顶光伏组件并网发电系统为例,通过分析组件在沙尘天气前后、雨雪天气前后的发电性能,结合组件表面积灰情况,分析冬春季沙尘天气对于光伏组件的发电性能影响。试验结果表明:冬春季沙尘天气后组件的发电性能明显下降;在维护困难,无法及时清洗的情况下,BIPV系统积灰量少,在发电性能上更具有优势。
In the dust affected area of northwest China,the sand and dust weather in winter and spring has a great impact on the power generation performance of PV modules.In this paper,taking the grid connected power generation system of roof photovoltaic modules in Xi’an area as an example,the impact of sand and dust weather and in winter and spring on the power generation performance of photovoltaic modules is analyzed by analyzing the specific power generation capacity of PV modules,combined with the dust-covered condition of PV module surface.The results show that the power generation performance of the module significantly decreases after sand and dust weather and in winter and spring.Cleaning has a significant increase in the power generation efficiency of the modules.However,in the case of difficult maintenance and unable to clean in time,The BIPV system has less dust accumulation and has more advantages in power generation performance.
