我们提出了一个计算双面组件户外性能（包括光学、电气和热学方面）的模型概要。模块总功率输出的 IV 曲线是通过将前后标准测试条件 (STC) 模块 IV 曲线的 2 二极管参数与计算出的前后辐照度进行缩放或加权而获得的。通过模拟和测量来验证和验证电气模型。针对垂直、东西向双面组件相对于朝南倾斜的单面组件，提出并讨论了基于双面组件测量特性的年产量增益预测。对于像阿姆斯特丹这样的地方双面系数为 92% 的组件，预计年产量增益在反照率 0.2 时约为 10%，在反照率 0.5 时约为 30%。
We present the outline of a model that calculates the outdoor performance of a bifacial module including optical, electrical and thermal aspects. TheIVcurve for the total module power output is obtained by scaling or weighting the 2-diode parameters of front and rear standard test conditions (STC) moduleIVcurves with the calculated front and rear irradiance. Validation and verification of the electrical model are given through simulations and measurements. Annual yield gain predictions based on measured characteristics of bifacial modules are presented and discussed for vertical,east-west bifacial modules relative to south-facing tilted monofacial modules. For a module with a bifaciality factor of 92% in a location like Amsterdam, this predicted annual yield gain is in the order of 10% at albedo 0.2 and 30% at albedo 0.5.
