The internal hidden damages such as hidden cracks, broken grids, virtual soldering, black cores, and PID attenuation in photovoltaic modules are important causes of the decline in power generation and frequent occurrence of hot spot faults in power plants. For a long time, traditional EL detection equipment has mostly been able to operate at night or in dimly lit dark rooms. The equipment is bulky and has a long detection cycle, making it difficult to meet the practical needs of large-scale on-site inspections in large power plants. To overcome the constraints of this industry, Shanghai LAILX has launched the LXG30 portable EL detector based on years of technological accumulation, achieving lightweight, all-weather, and high-efficiency non-destructive testing of internal defects in components.

LXG30 relies on the mature principle of electroluminescence imaging to apply forward excitation current to photovoltaic modules, which excites the solar cells to generate near-infrared luminescence signals. The device is equipped with a high pixel near-infrared CMOS imaging system and a professionally customized optical lens, which can clearly image even tiny cracks at the 0.1 millimeter level, accurately identify more than ten types of internal faults, and effectively avoid the problems of missed or false detections in ordinary detection equipment. What is even more disruptive is that the LXG30 is innovatively equipped with an intelligent light control adaptive system and a self-developed strong light suppression algorithm, which does not require the construction of a shading shed. It can also obtain high-quality EL images in the noon sunlight environment, completely breaking the limitation of traditional equipment that can only work at night and greatly extending the effective daily working hours.

In terms of portability and security design, LXG30 also performs well. The device is equipped with a large capacity rechargeable lithium battery, which supports long-term continuous work in the field. At the same time, the device supports WIFI wireless remote control, and staff can remotely control camera shooting and power on/off through tablets and mobile phones. This not only achieves fast imaging of a single component in seconds, but also keeps personnel away from high-voltage components, avoiding the risk of electric shock and further improving the safety of on-site operations. Paired with LAILX's self-developed intelligent image analysis system, defect recognition can be completed in a short period of time and preliminary detection reports can be output, resulting in a significant improvement in overall efficiency.

At present, the application scenarios of LXG30 have fully covered core links such as component factory inspection, project arrival acceptance, power station grid connection testing, and operation and maintenance stage fault troubleshooting, and are compatible with mainstream component products such as monocrystalline silicon, polycrystalline silicon, double glass, and half sheet. As a representative of domestically produced portable EL detection equipment, LAILX balances product performance and after-sales service, providing complete operation training and rapid after-sales response. In the current rapidly developing photovoltaic industry, LXG30, with its comprehensive advantages of all-weather operation and high-definition and accurate imaging, is helping the photovoltaic industry achieve full process quality control, and promoting photovoltaic operation and maintenance towards high efficiency and intelligence.
