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. In 2026, as the domestic photovoltaic industry shifts from "scale expansion" to "value competition", efficient operation and maintenance of power plants throughout their entire lifecycle has become the key to improving power generation revenue. For a long time, traditional EL detection equipment has mostly been able to operate at night or in dark rooms, with bulky equipment and long detection cycles, making it difficult to meet the practical needs of large-scale on-site inspections of large power plants in China. 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, and reshaping a new standard for domestic photovoltaic circle testing.

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 Lailx9s high-sensitivity infrared chip, which has an infrared refractive index of up to 99.8%. Even under weak current conditions of 5A, it can present clear hidden crack images with a resolution of up to 0.5mm/pixel, accurately identifying more than ten types of internal faults. 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 12 hours of long-lasting battery life and is suitable for long-term continuous work in outdoor environments. Supporting 2.4G Wi Fi wireless remote control, staff can remotely control camera shooting and power on/off from 10 meters away through tablets or mobile phones. This not only achieves fast imaging of a single component in seconds, but also keeps personnel away from high-voltage components and avoids the risk of electric shock. Combined with a 400nm safe laser positioning system and a 2-meter carbon fiber lightweight bracket, efficient and safe single person operations can be achieved even in complex terrains such as mountains and water surfaces.

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. The equipment adopts a three proof portable box design, perfectly adapting to various harsh outdoor operating conditions, from on-site acceptance of distributed photovoltaics to daily inspection of large ground power stations, it can handle everything with ease.
At present, as the domestic photovoltaic industry accelerates the fine operation and maintenance of power stations, LXG30 guards the efficient operation of every photovoltaic module with its keen "insight". It not only significantly improves the efficiency and accuracy of defect detection, but also provides solid technical support for the precise operation and asset preservation of photovoltaic power plants, helping the domestic photovoltaic industry achieve high-quality and safe development in value competition.
