摘要
不同的背景反射率对双面光伏组件的发电量影响较大,采用PVsyst软件对双面光伏组件的发电量进行模拟分析,采用不同支架安装方式时,设定不同背景反射率,得出双面光伏组件背面年发电量的增益情况。结论表明:在相同装机容量情况下,无论采用何种支架安装方式,采用双面光伏组件都可在仅增加少量投资的同时提高光伏发电系统的整体发电量,有利于提升光伏发电系统的综合利用率和经济性,降低光伏发电系统的度电成本,提升系统总体收益率。研究结果可用于指导光伏发电系统设计方案的优化和实施。
Bifacial PV modules installed under different background reflectivity have a greater impact on power generation.Using PVsyst software to simulate,by adopting different support installation methods and setting different background reflectivities and installing the same capacity maybe increasing a small amount of investment,but the overall power generation of the PV power station can be increased.This results can be used to guide the optimization and implementation of PV power station design schemes,which are beneficial to improve the comprehensive utilization and economy of PV power generation systems,reduce the system LCOE,and improve the overall profitability of the PV power station.
