As the core power generation unit of photovoltaic power plants, photovoltaic modules have hidden defects such as internal cracks, broken grids, virtual soldering, hot spots, PID decay, etc., which are the core factors leading to a decrease in power generation efficiency, shortened module service life, and safety hazards. Traditional appearance inspection methods are difficult to identify internal hidden defects, and professional EL inspection has become a key link in controlling the quality of photovoltaic modules. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) has launched the LXG50 portable EL detector with years of accumulation in photovoltaic defect detection technology. With the core advantages of high-definition imaging, intelligent recognition, and portable operation, it accurately captures small internal defects of components and provides reliable solutions for quality control of photovoltaic components throughout their lifecycle. Rapid detection instrument for hidden cracks in photovoltaic panels

The LXG50 portable EL detector focuses on detecting internal defects in photovoltaic modules, with industry-leading core imaging performance. The device is equipped with a 30 million pixel full frame industrial grade CMOS infrared chip, paired with a 17mm/95 ° wide-angle professional lens. The infrared imaging accuracy reaches * *>0.2mm/pixel * *, and the sensitivity can detect small hidden cracks with a crack width less than 0.2 μ m. It clearly presents more than 10 types of defect details such as internal hidden cracks, broken grids, fragments, virtual soldering, sintered mesh, black core, PID attenuation, etc., completely solving the problem of blurred imaging and missed detection of small defects in traditional EL detectors. Whether it is factory quality inspection during component production or on-site inspection during power plant operation and maintenance, LXG50 can accurately identify hidden defects and avoid subsequent losses caused by defective components being put into use.

Intelligent operation and convenient design, suitable for outdoor detection needs in all scenarios. LXG50 abandons the complex operation mode of traditional EL detectors and adopts WIFI wireless control+tablet real-time image transmission design. Operators can remotely control the device through the tablet without the need for close contact with high-voltage components, ensuring job safety. The device supports full-time low light autofocus, eliminating the need for manual distance measurement. Single component imaging detection can be completed in 3-10 seconds, greatly improving detection efficiency. The whole machine adopts a lightweight and portable design, paired with a high-strength protective box, which can adapt to harsh outdoor environments such as sun exposure, rain, and sandstorms. It can be easily carried by a single person to power plant sites, component warehouses, and other places without complex installation and debugging, and can be used right out of the box.

AI intelligent recognition and data-driven management empower efficient closed-loop detection work. The LXG50 is equipped with LAILX's self-developed AI defect recognition algorithm, which can automatically identify defects such as hidden cracks, broken grids, and virtual soldering in imaging images and accurately mark them. It also generates defect classification reports automatically, without the need for manual inspection and analysis, greatly reducing reliance on the professional experience of operators. The device supports integration with the Internet of Things cloud platform, and detection data can be uploaded in real time to the Lexus photovoltaic cloud platform, enabling cloud storage, remote viewing, and analysis of data. It supports power plant modeling and defect data tracing, facilitating the establishment of component quality files for enterprises and providing data support for subsequent operation and maintenance optimization and responsibility definition. At the same time, the device supports high and low current switching testing, which can adapt to the detection needs of different specifications of components, further enhancing the universality of the device.

Strict quality control and full cycle service ensure stable and reliable equipment. The LXG50 follows LAILX's rigorous quality standards from research and development, production to factory testing. The core components are equipped with internationally renowned brand industrial grade configurations and undergo multiple rounds of high and low temperature, vibration, and waterproof testing to ensure long-term stable operation of the equipment in complex environments. At present, LXG50 has been widely used in major photovoltaic module production enterprises, photovoltaic power station operation and maintenance companies, and third-party testing institutions in China, covering various scenarios such as distributed photovoltaics and large-scale ground power stations. With accurate detection capabilities and convenient operation experience, it has become the mainstream equipment in the field of photovoltaic defect detection.

In today's large-scale development of the photovoltaic industry, the quality of components directly determines the power generation efficiency, safety, and stability of power plants. The Suzhou LAILX LXG50 portable EL detector uses high-definition imaging technology to penetrate hidden defects, simplifies the detection process with intelligent operation, and adapts to all scene requirements with a portable design, providing efficient, accurate, and reliable detection methods for quality control of photovoltaic modules. In the future, LAILX will continue to focus on innovation in photovoltaic defect detection technology, continuously optimize product performance, help the photovoltaic industry improve product quality, reduce operation and maintenance costs, and promote the healthy and sustainable development of the industry.
