As the core component of power generation in power plants, photovoltaic modules have internal defects such as hidden cracks, broken grids, virtual soldering, and hot spots, which are the core causes of decreased power generation efficiency, premature module decay, and even safety accidents. These hidden defects cannot be recognized by the naked eye, and conventional detection methods are difficult to accurately locate, becoming a major challenge for the operation and maintenance of photovoltaic power plants. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) has innovatively launched the LXG50 portable EL detector based on years of photovoltaic detection technology accumulation. With four core advantages of 30 million pixel high-definition imaging, full-time dark light autofocus, AI intelligent defect recognition, and portable and efficient detection, it achieves fast, accurate, and visual detection of internal defects in photovoltaic modules, providing professional solutions for quality control throughout the entire life cycle of photovoltaic modules and becoming a "precise flaw detection tool" for photovoltaic power station quality inspection.

With the rapid development of the photovoltaic industry and the continuous upgrading of module technology, new types of modules such as half sheet, double glass, and stacked tile are becoming popular, which puts higher demands on the accuracy, efficiency, and adaptability of internal defect detection. Traditional EL detectors have pain points such as insufficient imaging clarity, cumbersome focusing, poor environmental adaptability, dependence on manual defect recognition, and poor portability: low pixel devices are difficult to capture micro level subtle cracks; Manual focusing operation is complex, difficult to focus in low light and inclined environments, and low detection efficiency; Artificially identifying defects is easily influenced by subjective factors, resulting in a high rate of missed or false detections; The equipment is bulky and requires multiple people to collaborate, making it difficult to adapt to outdoor mobile detection scenarios. The LAILX R&D team addresses industry pain points by integrating infrared imaging technology, intelligent control technology, and AI algorithms to create the LXG50 portable EL detector, achieving comprehensive innovation in detection accuracy, efficiency, intelligence, and portability, and accurately matching the testing needs of new photovoltaic modules.

The core competitiveness of LXG50 portable EL detector lies in its ultra high definition imaging capability and precise defect capture. 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 up to>0.2mm/pixel. It can clearly capture subtle defects such as hidden cracks, broken grids, and virtual soldering with a width of less than 0.2 μ m, perfectly adapting to the high-precision detection needs of various photovoltaic modules. Different from traditional devices, LXG50 adopts a patented full-time dark light autofocus system, which does not require manual intervention. It can quickly autofocus in complex environments such as low light, dark light, and inclined surfaces, solving the pain points of difficult focusing and blurry imaging in traditional devices, and improving detection efficiency by 7-8 times. Whether it is a strong light environment during the day or a weak light scene at night, it can accurately image and clearly present the details of internal defects in components, providing intuitive and reliable visual basis for defect determination.

Intelligent and convenient design comprehensively upgrades the detection experience of LXG50. The equipment is equipped with LAILX AI intelligent defect recognition system, which can automatically identify and mark 15 common defects such as hidden cracks, broken grids, fragments, virtual welding, sintering, PID attenuation, etc., and generate detection reports automatically. There is no need to manually analyze images one by one, greatly reducing the dependence on the professional ability of detection personnel and significantly reducing the rate of missed and false detections. Equipped with a 2.4G WIFI wireless control module, it supports wireless operation, real-time image transmission, and data download. The device can be remotely controlled through a tablet or mobile phone to achieve single person remote detection, making operation more convenient. The whole machine adopts a lightweight and portable design, equipped with a high-strength protective tripod and a dedicated shock-absorbing protective box. The equipment is easy to disassemble and assemble, and can be easily carried by a single person to various photovoltaic power plant sites such as mountains, roofs, deserts, etc. for rapid deployment and testing, completely bidding farewell to the drawbacks of traditional equipment being bulky and requiring multi person cooperation.

In terms of performance stability and environmental adaptability, LXG50 also performs outstandingly. The equipment is equipped with a programmable 2-in-1 detection power supply, which supports high and low current switching and can adapt to the detection needs of different types of components. The power supply has multiple protection functions such as short circuit, open circuit, overcurrent, and overheating, ensuring stable and safe operation. By adopting high-sensitivity infrared imaging technology, it can effectively filter out environmental light interference such as lighting, moonlight, and starlight. It can accurately detect both day and night, breaking the limitation of traditional EL detectors that can only detect at night, greatly improving detection flexibility and efficiency. The device is equipped with a large capacity lithium battery, which has a long battery life and can meet the needs of all day outdoor testing; Support 32GB storage card expansion, capable of storing massive detection images. Paired with dedicated analysis software, it can achieve image playback, defect comparison, data statistics, and report export, providing complete data support for component quality traceability and operation analysis. In addition, the equipment has good electromagnetic compatibility and can adapt to a wide temperature range of -20 ℃ to 50 ℃. It can still operate stably under harsh outdoor conditions such as high temperature, humidity, and dust, and its reliability and durability have been tested in harsh scenarios.

With excellent performance and reliable quality, the LXG50 portable EL detector has been widely used in various scenarios such as photovoltaic module factory quality inspection, power station arrival acceptance, post installation inspection, daily operation and maintenance, and third-party testing. In the component production process, defective components can be accurately screened and the factory quality can be strictly controlled; During the construction and acceptance stage of the power station, the quality of the received components can be comprehensively inspected to prevent defective components from entering the site; During the operation and maintenance of the power station, components can be regularly inspected to promptly detect hidden cracks, hot spots, and other hidden dangers, avoiding the expansion of defects that may lead to a decrease in power generation efficiency and ensuring the long-term stable and efficient operation of the power station. At present, the device has been highly recognized by large enterprises such as State Grid and China State Power, as well as numerous power plant owners and operation and maintenance companies. The market covers various major photovoltaic production areas in China and is exported to multiple countries and regions overseas, with excellent market reputation.

As an innovative leader in the field of photovoltaic testing equipment, Suzhou LAILX always focuses on industry pain points and customer needs, adheres to technological innovation and quality upgrading, and is committed to providing efficient, accurate, and reliable testing solutions for the photovoltaic industry. The LXG50 portable EL detector launched this time is another heavyweight work of LAILX in the field of photovoltaic defect detection. Its high-definition imaging, intelligent recognition, and portable and efficient features redefine the standard for portable EL detection, helping to improve the quality control of photovoltaic modules and the operation and maintenance level of power plants.
