双面PV（光伏）模块近来受到越来越多的关注，并且已经研究了各种系统设计。本文对垂直安装的东西向双面模块和传统安装的单面模块进行了全球比较。用解析方法计算了这两种结构的辐射。它被发现，这两个模块配置的问题的答案表现更好强烈地依赖于三个因素：（i）纬度，（ii）当地的扩散分数和（iii）的反射。在本文的后续部分中，计算了世界上每个地方垂直安装双面模块获得更好性能所需的最小可达性。计算基于漫射光部分的测量数据，并且结果以全局图的形式示出。最后，比较了所测得的全球性的分布的EQUIDO的要求。计算允许明确决定哪个模块配置更适合世界上的某个地方。结果还显示为定义相应区域的地图。
Bifacial PV (photovoltaic) modules have recently come to increasing attention and various system designs have been investigated. In this paper, a global comparison is made between vertically mounted bifacial modules facing East–West and conventionally mounted mono-facial modules. An analytical method is used to calculate the radiation received by these two module configurations. It is found that the answer to the question which of these two module configurations performs better strongly depends on three factors: (i) the latitude, (ii) the local diffuse fraction and (iii) the albedo. In a subsequent part of the paper, the minimum albedo required to result in a better performance for vertically mounted bifacial modules is calculated for every place in the world. The calculation is based on measured data of the diffuse light fraction and the results are shown in the form of a global map. Finally, the albedo requirements are compared with the measured global albedo distribution. The calculation allows a distinct decision which module configuration is more suitable for a certain place in the world. The result is also shown as a map defining the corresponding areas.
