It is important to measure the operating voltage of a cell sealed in a photovoltaic module as well as well‐known faults such as abnormal hot spots observed by thermography or a dark part in electroluminescence distribution on the module for detecting a fault module. This paper proposes a method that radiating modulated light toward a cell and extracting the synchronized signal from the module output by phase detector can estimate the operating voltage quantitatively by using a standard line predicted by shading the module partially.
