Overview

The portable EL detector is based on the principle of electroluminescence, which can generate electroluminescence by applying a forward bias voltage to the photovoltaic module, and then capture the luminescence image using professional imaging equipment. Due to the internal defects of components that can affect the conduction of current and the emission of light, these defects will appear in abnormal forms such as dark areas and dark lines in EL images, allowing inspectors to intuitively and accurately locate the location and type of defects. This detection method has the characteristics of non-destructive, high sensitivity, and high resolution, which can effectively detect internal defects of photovoltaic modules and provide reliable basis for quality control.
