With the vigorous development of the photovoltaic industry today, photovoltaic panels as the core components of solar power generation, their quality and performance are directly related to the efficiency and stability of the entire photovoltaic power generation system. However, photovoltaic panels in the production, transportation and use of the process, will inevitably be affected by various factors, resulting in internal defects or failures. In order to discover and solve these problems in time, the photovoltaic panel EL detector came into being and has become an important tool for the quality inspection and maintenance of photovoltaic modules.
EL detector, full name of electroluminescence detector, is a device that uses the electroluminescence principle of crystalline silicon to detect internal defects of solar cell modules. When a forward voltage is applied to a photovoltaic cell module, the material inside the module excites photons, which are captured by a highly sensitive camera and converted into a visual image, thereby visually demonstrating the defects and failures inside the photovoltaic cell module. So, what are the specific functions of the WX-EL1 photovoltaic panel EL detector?
The EL detector uses a high-precision optical and electronic system to accurately capture the weak light signal emitted by the photovoltaic panel and convert it into a clear image. These images can clearly show the cracks, black spots, virtual welding, broken network and other defects inside the photovoltaic module, helping the production enterprise and operation and maintenance personnel to find and deal with these problems in time to ensure the quality and performance of the photovoltaic module.
Compared with traditional destructive testing methods, EL detector has significant advantages in non-destructive testing. It does not cause any physical damage to the photovoltaic panel, while accurately detecting defects and problems inside the panel. This non-contact detection method not only protects the integrity of the photovoltaic module, but also improves the detection efficiency and accuracy.
In the process of construction and operation and maintenance of photovoltaic power stations, a large number of photovoltaic modules need to be tested. The EL detector has an efficient detection capability and can complete the detection work of a large number of photovoltaic panels in a short time. This not only improves the detection efficiency, but also reduces the labor cost and time cost, and provides strong support for the rapid construction and efficient operation and maintenance of photovoltaic power stations.
