将双面光伏组件安装在不同材质地面上，研究了双面光伏组件在户外环境下的发电性能。结果表明：在当前组件安装方式下，沙土地面上相同标称功率的双面光伏组件的年平均发电量比常规单面光伏组件的增益18.21%；水泥白漆地面上相同标称功率的双面光伏组件的年平均发电量比常规单面光伏组件的增益24.33%；碎石地面上相同标称功率的双面光伏组件的年平均发电量比常规单面光伏组件的增益18.72%。

The bifacial photovoltaic (PV) modules were installed on different materials ground, and the power generation performance of the bifacial PV modules in outdoor environment was studied. The results show that the annual average power generation of bifacial PV module with the same nominal power on the sandy ground was 18.21% higher than that of conventional unifacial PV module under the current module installation mode. The annual average power generation of bifacial PV module with the same nominal power on the cement white paint ground was 24.33% higher than that of conventional unifacial PV module. The annual average power generation of bifacial PV module with the same nominal power on the gravel ground was 18.72% higher than that of conventional unifacial PV module.
