360W超高功率n型双玻双面发电组件研究及应用

STUDY ON 360 W PV MODULE AND APPLICATION OF n-TYPE BIFACIAL PV MODULE

采用单块组件及3.42 kW电站系统的形式,对不同安装方式及不同反光背景条件下n型双玻双面发电组件的发电量进行跟踪;同时,对超高功率n型双玻双面发电组件进行研究。研究结果表明:在单块组件的理想条件下,双玻双面发电组件的平均单瓦发电量增益为21.38%,最高可达32.99%;在3.42 kW电站系统中,采用较好的反光背景,双玻组件的平均单瓦发电量增益约为13.37%;另外,采用n型"叠瓦"双玻双面发电的形式,组件的综合功率达到361.06 W。

In this work,it systematically compared the energy output of single n-type bifacial module with different installation at various albedos,even more analyzed the performance of 3.42 kW bifacial PV system. The results showed that one-module system under typical albedo condition,the average power gain per watt(APGE)of n-type bifacial module reaches 21.38%,and the maximum can be 32.99% for white stone surrounding. While APGE was just around 13.37% with white reflective background for 3.42 kW PV system,due to the same PV system design as conventional mono-facial PV module,which limited the incident light from rear side of bifacial PV module. In addition,n-type bifacial module with ultra-high power was studied,combining shingling technology and bifacial module testing method,the certified comprehensive power of 361.06 W PV module can be achieved.
