As the core power generation unit of photovoltaic power plants, photovoltaic modules have hidden defects such as internal cracks, broken grids, virtual welding, hot spots, PID attenuation, etc., which are the core causes of decreased power generation efficiency, shortened service life, and even safety accidents. These defects are difficult to identify with the naked eye and conventional detection methods are difficult to accurately locate, which has long been a pain point for quality control and efficient operation and maintenance of photovoltaic power plants. Based on industry demand, Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) is deeply engaged in the research and development of electroluminescence (EL) imaging technology. With years of technical accumulation and scene testing optimization, it has launched the LXG50 portable EL detector, which provides professional solutions for defect detection of photovoltaic modules with the core advantages of high-definition imaging, precise recognition, portability and high efficiency, and intelligent analysis. It has become a "perspective weapon" for quality protection of photovoltaic power plants. Photovoltaic panel testing instrument

As a professional equipment dedicated to detecting internal defects in photovoltaic modules, LXG50 is equipped with an industry-leading imaging system to achieve high-definition and precise defect detection. The device is equipped with a 30 million pixel full frame industrial grade CMOS infrared chip, paired with a 17mm/95 ° wide-angle infrared lens, with an imaging accuracy of>0.2mm/pixel. It can clearly capture fine cracks with a width of less than 0.2 μ m, accurately identify more than ten common internal defects such as hidden cracks, broken grids, fragments, virtual soldering, sintered mesh, black cores, mixed gears, PID attenuation, etc., and cover component quality hazards without blind spots. Compared to traditional EL detectors, the LXG50 adopts the Lexus patented full-time dark light autofocus system, which does not require manual distance measurement and can quickly focus and image both day and night. Even under complex lighting conditions such as low light and backlight, it can present clear and sharp imaging effects, completely solving the problems of tedious focusing and blurry imaging in traditional equipment.

The efficient and convenient operation design allows the LXG50 to easily adapt to the needs of full scene detection. The equipment adopts a lightweight and integrated design, with a compact size and light weight, and is equipped with a high-strength protective box. It can be easily carried by a single person to complex work scenarios such as mountains, deserts, rooftops, etc. The installation and debugging process is simple and fast, without the need for professional skills. Assembly and debugging can be completed in 5 minutes after unboxing, greatly improving the efficiency of on-site operations. The LXG50 supports WIFI wireless operation, image transmission, and data download. Operations personnel can remotely control the device through their mobile phones or tablets to view imaging images in real time without the need for close range operations, improving job safety. At the same time, the device is equipped with a programmable 2-in-1 detection power supply, which can wirelessly adjust current parameters and adapt to the detection needs of different specifications of components, without the need for additional power equipment configuration, simplifying the operation process.

The intelligent AI analysis function greatly improves the efficiency of defect detection and diagnosis. The LXG50 is equipped with an AI intelligent defect recognition algorithm independently developed by Lexus, which can automatically identify various types of defects in the imaging image, accurately mark the position, type, and size of defects, without the need for manual frame by frame analysis, and improve detection efficiency by more than 60%. The device supports automatic generation of detection reports and can export standardized reports containing defect images, location annotations, and defect type statistics with just one click, making it easy to archive, trace, and make operational decisions. At the same time, LXG50 has cloud platform data upload and storage functions, which can synchronize detection data to the cloud, achieve multi device data sharing, remote management, and historical data comparison analysis, and help power plants establish a full lifecycle quality control system.

With excellent performance and wide adaptability, LXG50 has been deeply applied in multiple scenarios such as photovoltaic power station arrival acceptance, post installation testing, daily operation and maintenance, laboratory testing, etc. It is compatible with various component types such as monocrystalline silicon, polycrystalline silicon, double glass, perovskite, and half sheet. In the acceptance stage of the power station, a comprehensive defect survey of all power station components can be quickly completed, and unqualified components can be accurately screened to control the construction quality of the power station from the source; During the operation and maintenance phase, regular EL testing can promptly detect hidden defects within components, intervene in maintenance in advance, avoid the expansion of defects leading to a significant decrease in power generation efficiency, and extend the service life of components; In the component production and quality inspection process, it can be used for production line sampling and finished product testing to strictly control product quality and enhance product competitiveness.

As a benchmark enterprise in the field of photovoltaic testing equipment, LAILX in Suzhou has always adhered to technological innovation and quality upgrading. With its strong technical research and development capabilities, strict production control system, and perfect after-sales service network, it has won high recognition from global customers. In the future, LAILX will continue to focus on the development trends of the photovoltaic industry and core customer needs, continuously optimize EL imaging technology and AI analysis algorithms, launch more intelligent and efficient detection equipment, help upgrade the quality and efficient operation and maintenance of the photovoltaic industry, and safeguard the global development of clean energy.
