不同安装倾角对双面光伏组件光伏电站发电量的影响研究

RESEARCH ON INFLUENCE OF DIFFERENT INSTALLATION ANGLES ON POWER GENERATION OF PV POWER STATION ADOPTING BIFACIAL PV MODULES

双面光伏组件采用固定支架运行方式时,在保持支架前、后排间距不变的情况下,当双面光伏组件的安装倾角不同时,组件背面接收的太阳辐射量不同,从而导致光伏电站总发电量也会不同。采用PVsyst软件模拟了不同安装倾角时双面光伏组件背面接收的太阳辐射量增益及光伏电站首年发电量情况,以便在有限的占地面积下充分利用双面光伏组件背面发电的特性,以期为今后光伏电站的设计方案比选、设计优化等工作提供依据。

With using fixed bracket and keep the distance between front and back row of bracket unchanged,when the installation angle of bifacial PV modules is different,the solar radiation received by rear of bifacial PV modules is different,resulting in different total power generation of PV power station.PVsyst software is used to simulate the solar radiation gain received on rear of bifacial PV module and first-year power generation of the PV power station when the installation angle is different.An optimization design of installation angle for bifacial PV module in a limited space can provide a basis for further PV power station design.
