纳米自清洁薄膜在光伏电站中的应用

APPLICATION OF NANO SELF-CLEANING FILM IN PV POWER STATION

自然条件下,光伏组件表面的积灰会造成光伏组件的输出功率显著降低,而采用含有纳米级TiO_(2)光催化的自清洁薄膜(下文简称为“纳米自清洁薄膜”)后,光伏组件具有可验证测量的自清洁效果及良好的耐候性,并且可增加光伏组件的输出功率。本文通过实验验证分析,选取我国典型的灰尘污染严重的地区——内蒙古自治区乌拉特中旗川井镇作为实验基地,对光伏组件玻璃表面采用纳米自清洁薄膜的应用效果进行了验证,通过对选定的逆变器对应的光伏方阵的发电量进行持续跟踪后发现:该纳米自清洁薄膜可有效减少灰尘在光伏组件表面的累积,相比于未采用纳米自清洁薄膜的光伏方阵,采用了纳米自清洁薄膜后光伏方阵的发电量增幅达3%以上。

Under natural conditions,the dust accumulation on the surface of PV modules will significantly reduce the output power of PV modules,after adopting the self-cleaning film containing nano-TiO_(2) photocatalysis(hereinafter referred to as“nano self-cleaning film”),the PV modules have verifiable and measured self-cleaning effect and good weather resistance,and can increase the output power of PV modules.Through experimental verification and analysis,this paper selects Chuanjing Town,Urad Middle Banner,Inner Mongolia Autonomous Region,a typical area with serious dust pollution in China as the experimental base to verify the application effect of nano self-cleaning film on the glass surface of PV modules.After continuously tracking the power generation capacity of the PV array corresponding to the selected inverter,it is found that the application of nano self-cleaning film can effectively reduce the accumulation of dust on the surface of PV modules.Compared with the PV array without nano self-cleaning film,the power generation of PV array with nano self-cleaning film increases by more than 3%.
