Monitoring the performance of solar modules in a photovoltaic system is critical in order to understand the health of the system. Existing methods for field inspection have limited capability of detecting various electronic defects that can, however, be identified with luminescence‐based methods. A contactless outdoor photoluminescence‐imaging based measurement method that uses the sun as the excitation source was presented in our earlier work. This paper extends our previous work and presents two unique applications to (a) identify and quantify local areas of high series resistance within the cells and (b) identify bypass diodes that have failed in open‐circuit. The paper also discusses specific technical considerations of this method. The main merit of this method is that it can be used when the module is under normal operation in the field, without requiring changing of the electrical wiring of the photovoltaic array.

通过非接触式开关对太阳能电池板进行室外光致发光成像：技术考虑和应用

为了了解系统的健康状况，监视光伏系统中太阳能模块的性能至关重要。现有的现场检查方法检测各种电子缺陷的能力有限，但是可以使用基于发光的方法进行识别。在我们较早的工作中提出了一种基于非接触式户外光致发光成像的测量方法，该方法使用太阳作为激发源。本文扩展了我们之前的工作，并提出了两个独特的应用：（a）识别和量化电池单元内高串联电阻的局部区域，（b）识别开路失败的旁路二极管。本文还讨论了此方法的具体技术注意事项。这种方法的主要优点是可以在模块在现场正常运行时使用，
