As the core carrier of power generation in power plants, photovoltaic modules have hidden defects such as internal cracks, virtual welding, hot spots, PID decay, etc., which are difficult to detect with the naked eye in the early stage, but gradually reduce the power generation efficiency, and in severe cases, may cause safety accidents such as module burnout and power plant shutdown. Traditional fixed EL detectors are bulky, cumbersome to transport, and have poor outdoor adaptability, making it difficult to meet the on-site detection needs of diversified scenarios such as distributed photovoltaics, mountain photovoltaics, and household photovoltaics. With over ten years of experience in the research and development of photovoltaic detection equipment, LAILX in Suzhou has accurately grasped industry pain points and launched the LXG30 portable EL detector. With four core advantages of extreme portability, high-definition imaging, intelligent control, and all-weather operation, LAILX has created a lightweight, high-efficiency, and high-precision component defect detection solution, becoming the "mobile inspector" for quality control throughout the entire lifecycle of photovoltaic power plants.

In recent years, the global photovoltaic industry has entered a new stage of high-quality development, and the construction scenarios of power stations have become increasingly diversified. From large-scale ground power stations to distributed roof power stations, from mountains and hills to water surfaces and mudflat, complex scenarios put forward higher requirements for the portability and environmental adaptability of detection equipment. At the same time, the iteration of photovoltaic module technology is accelerating, and new types of modules such as half panels, stacked tiles, and double glass are popularized. The internal structure is more precise, and the accuracy and clarity requirements for defect detection are greatly improved. Traditional portable EL detectors have problems such as blurred imaging, low recognition rate of hidden cracks, complex operation, and inability to operate during the day, making it difficult to adapt to the detection needs of new components, resulting in frequent missed and misjudgments of defects, which affects the long-term stable operation of power plants. The LAILX R&D team has gathered core technical talents in the fields of optical imaging, intelligent algorithms, and structural design. After hundreds of rounds of technical research and field testing, they have polished the LXG30 portable EL detector, achieving comprehensive breakthroughs in detection accuracy, efficiency, and portability.

The core competitiveness of LXG30 lies in high-definition imaging and precise defect recognition, capturing hidden defects in micrometer level components. The device is equipped with a 24 megapixel full frame industrial CMOS sensor, paired with a 95 ° wide-angle infrared lens and a dedicated filter. The imaging clarity is improved by more than 60% compared to traditional devices, and can accurately capture micro level hidden cracks, fine virtual welding, battery cell mixing, fragments, and other defects inside the components. Even small thermal spot attenuation areas can be clearly presented, with a defect recognition rate of up to 99.9%, completely solving the problem of missed and false detections in traditional equipment. Supporting fast imaging in 5 seconds, combined with LAILX's self-developed intelligent image analysis system, single component detection can be completed and preliminary defect reports can be generated within 30 seconds, which is more than 50% more efficient than traditional portable devices. Taking a 100MW ground power station as an example, traditional equipment can detect about 150 components in a single day, while LXG30 can complete more than 500 components in a single day, greatly shortening the inspection cycle of the entire power station and reducing operation and maintenance manpower and time costs. Simultaneously supporting synchronous imaging of 1-12 components, it can batch detect string components and adapt to the batch operation and maintenance needs of centralized power plants.

Extremely portable and flexible deployment design, perfectly adapted to the needs of outdoor detection in all scenarios. The LXG30 weighs only 2.8kg, which is 30% lighter than similar products. Paired with a lightweight portable backpack, it can be easily carried by a single person to complex scenes such as roofs, mountains, and hills, without the need for heavy handling equipment, greatly improving outdoor inspection flexibility. Adopting a foldable tripod design, the length after storage is only 50cm, and the height can be freely adjusted after unfolding, adapting to different height component detection. Equipment deployment and debugging can be completed within 5 minutes, truly achieving "out of the box, anywhere detection". Innovatively adopting military grade anti infrared darkroom technology, it does not require the construction of a fixed darkroom and can operate directly in strong light environments during the day, completely breaking the limitation of traditional EL detectors that can only detect at night, greatly extending operation time, improving detection efficiency, and adapting to various outdoor all-weather detection scenarios.

In terms of intelligent control and data management, LXG30 balances convenience and professionalism, reducing the threshold for operation. The device supports wireless remote control on iPad and PC, coupled with barcode scanning function, which can quickly identify component numbers, achieve precise binding between components and detection data, and facilitate data traceability and management in the later stage. Equipped with a fully Chinese operating interface, the touch screen operation is simple and intuitive, and beginners can quickly get started without professional training. It supports one click imaging and one click report generation, with a minimalist operation process. Built in large capacity lithium battery, with a battery life of up to 8 hours, can meet all day outdoor testing needs, supports fast charging, can be fully charged in 2 hours, suitable for long-term field operations. The built-in memory of the device can store more than 10000 sets of detection images, support USB and WiFi data transmission, and is equipped with professional analysis software on the PC side. It can achieve functions such as image enlargement, defect annotation, report export, and data archiving, meeting the report submission and data traceability needs of third-party detection agencies and power station operation and maintenance.
In addition, LXG30 has excellent environmental adaptability and safety protection capabilities, suitable for harsh outdoor working conditions. The body is made of industrial grade ABS material, with a dustproof and waterproof rating of IP64. It can operate stably in temperature environments ranging from -10 ℃ to 50 ℃, and resist harsh environmental influences such as outdoor humidity, sand and dust, and slight rain. Adopting secure patented power technology, the output voltage is stable and safe, effectively avoiding damage to components caused by overvoltage and overcurrent, ensuring the safety and reliability of the detection process. The equipment has passed multiple international certifications such as CE and FCC, and its quality meets the highest industry standards. It can adapt to various global photovoltaic module testing needs.

At present, the LXG30 portable EL detector has been widely used in the entire process of component factory quality inspection, power station arrival acceptance, installation process sampling, operation and maintenance troubleshooting, covering various scenarios such as centralized ground power stations, distributed roof power stations, household photovoltaics, mountain photovoltaics, etc. With excellent performance and reliable quality, it has become the preferred equipment for industry customers. In the future, LAILX in Suzhou will continue to deeply cultivate photovoltaic defect detection technology, continuously optimize product performance, launch more innovative detection equipment, help improve the quality and efficiency of the photovoltaic industry, and safeguard the safe and efficient operation of global photovoltaic power plants.
