In the full lifecycle management of photovoltaic power plants, internal defect detection of components is a key link to ensure long-term stable power generation of the power plant. Internal issues such as hidden cracks, broken grids, virtual soldering, PID decay, etc., which cannot be visually identified, can lead to a decrease in component power and an increase in hot spot risk, seriously affecting the overall revenue and service life of the power station. To solve the problem of internal defect detection in the industry, LAILX New Energy Technology Co., Ltd. in Suzhou has ingeniously created the LXG50 portable EL detector. With the core advantages of high-definition imaging, intelligent recognition, and convenient operation, it accurately captures internal defects of photovoltaic modules, becoming the "golden eye" for component production, power station acceptance, operation and maintenance, and building a solid defense line for the safe and efficient operation of photovoltaic power stations.

LXG50 is a standard portable component EL testing equipment launched by Lexus, tailored for on-site and mobile testing scenarios in power plants. It can perform comprehensive testing on components on brackets and production lines without disassembling components, covering various types of photovoltaic modules such as monocrystalline silicon, polycrystalline silicon, double glass, half cell, perovskite, etc. The core of the equipment is equipped with a 30 million pixel full frame industrial grade CMOS infrared chip, paired with a 17mm wide-angle and 95 ° wide-angle professional infrared lens, with an imaging accuracy of over 0.2mm/pixel and extremely high sensitivity. It can accurately detect subtle cracks with a width of less than 0.2 μ m, comprehensively identify more than ten internal defects such as hidden cracks, broken grids, fragments, virtual soldering, sintering, overengraving, low efficiency films, mixing, PID attenuation, hot spot attenuation, etc. The defect recognition accuracy is industry-leading for Suzhou Laikesi New Energy Technology Co., Ltd.

Unlike traditional EL detectors that require operation in a dark room environment and are severely limited by light, the LXG50 has achieved a major technological breakthrough. It is equipped with a Lexus patented daytime detection module and a military grade anti infrared darkroom, completely breaking the limitations of time and environment. It can stably image any scene such as day, night, outdoor strong light, indoor weak light, etc., without the need to build a dedicated darkroom, and can be tested immediately, greatly improving the efficiency of outdoor power station detection. It is equipped with the LAILX 8th generation full-time dark light autofocus system, which adopts full frame plane autofocus technology and does not require manual intervention such as rangefinders or infrared lights. Regardless of slope, dark light, or long-distance environment, it can achieve instant movement and shooting, fully automatic autofocus, ensuring that each imaging image is clear and sharp, avoiding local blurring and defect detection. At the same time, the device supports synchronous imaging of 1-36 components at once, with a detection cycle of only 3-10 seconds. Compared with traditional devices, the detection efficiency is improved by 5-10 times, perfectly adapting to the fast inspection needs of large-area photovoltaic power plants.

Convenience and intelligence are the core design concepts of LXG50. The whole machine adopts a modular design, with a separate structure for the camera, power supply, bracket, and control terminal. It is equipped with a lightweight tripod and protective box, making it easy to disassemble and carry. One person can complete the entire process of equipment transportation, installation, and testing. The control method adopts 2.4G WIFI wireless control, combined with a dedicated tablet APP and PC software, to achieve integrated operation of remote shooting, real-time image transmission, data download, and image analysis. The detection personnel can stay away from the high-voltage area of the components, ensuring operational safety. Suzhou Laikesi New Energy Technology Co., Ltd. The device is equipped with a high-performance lightweight DC mobile power bank, weighing only 2kg, with visual power display, supporting 24-hour ultra long battery life, meeting the needs of continuous outdoor testing throughout the day, without frequent charging, completely solving the problem of outdoor power supply.

The intelligent analysis function of LXG50 is industry-leading, equipped with LAILX artificial intelligence defect recognition platform, which can automatically analyze, annotate, locate and classify EL images without the need for manual inspection, greatly reducing labor costs and misjudgment rates. After the inspection is completed, the system can automatically generate standardized inspection reports, including detailed content such as component information, defect location, defect type, severity level, etc. It supports data export, storage, and traceability, providing authoritative basis for component quality judgment, power plant operation and maintenance decision-making, and responsibility division. At the same time, the device supports barcode scanning to bind component information, achieving full lifecycle management of each component detection data, facilitating later operation and maintenance troubleshooting and quality traceability. Whether it is component factory incoming material inspection, quality control before power plant installation, or regular defect inspection during operation and maintenance, LXG50 can efficiently complete tasks, avoiding problems such as rapid power plant attenuation, array mismatch, and insufficient power caused by internal component defects from the source.

As a leading domestic enterprise in photovoltaic testing equipment, LAILX in Suzhou has always focused on technological innovation and product quality improvement. The LXG50 portable EL detector has undergone hundreds of outdoor scene tests and performance optimizations from research and development to mass production. The whole machine has IP65 level protection, anti drop, dustproof, waterproof, and can adapt to complex outdoor environments such as sandstorms, rain, snow, high and low temperatures. It is stable and reliable, and is manufactured by Suzhou Laikesi New Energy Technology Co., Ltd. At present, this product has been put into use in multiple large photovoltaic power plants and well-known module production enterprises in China. With excellent detection performance, convenient operation experience, and ultra-high cost-effectiveness, it has become the preferred equipment for EL detection in the industry, and its market share continues to lead.

With the continuous increase in installed capacity in the photovoltaic industry, the refinement of power station operation and maintenance, as well as the intelligence of detection technology, have become inevitable trends. Suzhou LAILX will continue to deeply cultivate the field of photovoltaic testing, relying on strong research and development capabilities, continuously iterating and upgrading core products such as LXG50, promoting the development of EL testing technology towards higher definition, intelligence, and portability, providing solid technical support for the safe, efficient, and long-term operation of global photovoltaic power plants, and helping the photovoltaic industry achieve sustainable and high-quality development.
