As the core power generation component of photovoltaic power plants, photovoltaic modules have hidden defects such as internal cracks, fragments, virtual welding, broken grids, hot spots, and black chips, which are key factors affecting the power generation efficiency of the power plant, shortening the service life of the modules, and causing safety hazards. Traditional appearance inspection methods are difficult to penetrate the surface of components and accurately identify small internal defects, posing many challenges to the construction acceptance, daily operation and quality control of photovoltaic power plants. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) focuses on the pain points of photovoltaic module defect detection and has developed the LXG30 portable EL detector with heavy research and development. With the core advantages of high-definition imaging, precise recognition, and portable efficiency, it has become the "perspective eye" for photovoltaic module defect detection, comprehensively safeguarding the quality and efficiency of photovoltaic power plants.

EL (Electro Luminescence) detection technology is currently the core means of detecting internal defects in photovoltaic modules. By applying a forward bias to the module, the battery cell emits infrared light, which is captured by an infrared camera for imaging, allowing for a visual presentation of microscopic defects inside the module. The LAILX LXG30 portable EL detector is based on advanced EL detection principles, integrating self-developed imaging technology and portable design, completely breaking the limitations of traditional EL detectors such as large size, fixed site, and cumbersome operation, and achieving on-site, fast, and accurate detection of defects in photovoltaic modules.

The core imaging performance determines the accuracy of defect detection, and the LXG30 has reached the industry's high-end level in key configurations. The device is equipped with a high-resolution infrared imaging chip, paired with a 17mm/95 ° wide-angle lens, which has high infrared imaging clarity and can accurately capture subtle defects inside the components. The detection sensitivity is extremely high, and it can identify small hidden cracks with a crack width less than 0.2 μ m. The imaging accuracy is greater than 0.2mm/pixel, ensuring that all types of hidden defects have nowhere to hide. The detectable defect types are comprehensive, covering more than ten common problems such as hidden cracks, broken grids, fragments, virtual soldering, sintering, over etching, low efficiency chips, thermal spot decay, PID defects, etc., comprehensively covering the main quality hazards in the production and operation process of photovoltaic modules.

Portability and efficient design are the core advantages of LXG30 in adapting to on-site testing. The equipment adopts a lightweight integrated design, and the entire set of equipment is stored in a portable protective box. It is lightweight and small in size, and can be easily carried by a single person to any position in the power station without relying on a fixed testing site. The deployment process is minimalist, with adjustable tripods and 360 ° gimbals, and equipment setup and debugging can be completed in 2 minutes. It is ready to use without the need for professional technicians. The detection speed is efficient, with a single component detection cycle of only 3-10 seconds. It supports dual component self powered power on detection and can quickly complete large-scale screening of power plant components, greatly improving the efficiency of operation and maintenance detection.

In terms of operational experience and intelligent functions, LXG30 meets the actual needs of on-site operation and maintenance. Supports WIFI wireless operation and real-time image transmission, allowing remote control of shooting and real-time viewing of imaging images through PAD or PC, without the need for close range operation, suitable for complex detection scenarios such as high altitude and narrow spaces. Equipped with fully automatic autofocus function, no distance measurement, no manual autofocus, and can quickly and clearly image in low light environments, reducing the operating threshold. Built in large capacity battery, supports 24-hour ultra long battery life, meets all day outdoor testing needs, and does not require frequent charging. After the inspection is completed, a defect detection report can be generated with one click, automatically marking the location, type, and size of the defect, supporting data export and printing, providing intuitive basis for quality assessment and responsibility identification.

To adapt to various complex detection environments, LXG30 is equipped with a patented military grade anti infrared darkroom, which can carry out detection work in any environment such as strong light, day, night, etc., without being affected by external light interference, ensuring stable and clear imaging quality. Whether it is component incoming inspection before power station construction, completion acceptance after installation, or daily operation and maintenance during operation, troubleshooting of faulty components, LXG30 is capable of accurately identifying various hidden defects, controlling component quality from the source, avoiding power attenuation and loss of power generation revenue in the later stage, and reducing the probability of safety accidents.

Suzhou LAILX has been deeply involved in the field of photovoltaic testing for many years, always guided by user needs and centered on technological innovation. The development and launch of the LXG30 portable EL detector has filled the market gap for portable high-precision EL detection equipment and provided an efficient solution for quality control throughout the entire lifecycle of photovoltaic power plants. In the future, LAILX will continue to optimize product performance, iterate and upgrade detection technology, provide higher quality and more professional detection equipment and services for the photovoltaic industry, help improve the quality and efficiency of photovoltaic power plants, and promote the sustainable and healthy development of the clean energy industry.
