The internal defects of photovoltaic modules are the core hidden dangers that affect the power generation efficiency and service life of power plants. Traditional visual inspection is difficult to detect micro defects such as hidden cracks, virtual welding, and broken grids, and large EL detection equipment cannot adapt to outdoor and mobile scenarios. To solve this industry problem, the portable EL detector LXG30, carefully developed by LAILX in Suzhou, has been officially launched. With high-definition imaging, precise identification, and portable design, it has become a "mobile sentinel" for detecting internal defects in photovoltaic modules, injecting new momentum into the quality control of the photovoltaic industry.

The core advantage of LXG30 lies in the perfect balance between portability and precision. The total weight of the machine is only 3-5 kilograms, adopting an integrated compact design, equipped with anti slip handle and anti drop wear-resistant shell, reaching IP54 protection level, which can adapt to complex environments such as dust and light rain in outdoor power plants, and meet the needs of long-term outdoor work. The device is paired with a customized portable storage box, which can be easily carried by a single person. It can be quickly deployed to any scene such as rooftop photovoltaics, ground power stations, and distributed photovoltaic projects, completely breaking the limitations of traditional EL detection equipment fixed workstations and achieving "mobile detection and full coverage". Whether it is small photovoltaic power plants in remote mountainous areas or distributed projects on urban building roofs, LXG30 can conduct inspections at any time, greatly improving the efficiency of defect investigation.

In terms of core detection performance, the LXG30 is equipped with a high-sensitivity EL imaging system and advanced optical lenses, which can accurately capture subtle defects inside photovoltaic modules. The device excites the components to emit light by applying an electric field, presenting clear electroluminescence images inside the components. It can effectively identify more than ten common defects such as hidden cracks, broken gates, virtual soldering, fragments, poor sintering, and low efficiency chips. Its imaging resolution is as high as 20 million level, and the image details are clear and distinguishable. Even small cracks or virtual welding traces can be accurately captured, and the detection accuracy far exceeds traditional visual inspection, providing a reliable basis for component quality control. For different types of components such as single crystal (PREC, TOPCON, N-type) and polycrystalline, LXG30 is compatible with multiple detection parameter templates, with strong compatibility, and can meet the detection needs of all categories of components.

The LXG30 also performs well in terms of intelligent operation and data management. The device adopts a touch based operation interface, with simplified and clear processes, supporting functions such as fast imaging, real-time image annotation, defect classification and statistics. Staff can quickly master the operation methods without professional training. During the detection process, the system can automatically mark the location and type of defects, and generate detailed detection reports, including defect images, quantities, distribution information, etc. It supports wireless data transmission and cloud storage, facilitating subsequent analysis and traceability. At the same time, the device is equipped with a detection parameter library for multiple component models, supporting parameter customization and adjustment to adapt to component detection of different sizes and specifications, further improving detection efficiency and adaptability.

From the perspective of practical application value, LXG30 runs through the entire process of photovoltaic module production, installation, and operation and maintenance. At the production end, it can be used for full inspection of components before leaving the factory, timely eliminating unqualified products with internal defects, and improving the quality and brand reputation of enterprise products; During the installation and acceptance stage, it is possible to conduct rapid spot checks on newly installed components, identify potential hidden damages that may occur during transportation and installation, and avoid power generation losses caused by defective components in the later stage; On the operation and maintenance end, regular inspections of photovoltaic power plant components can be carried out to accurately locate faulty components, provide precise basis for maintenance and replacement, extend the service life of the power plant, and improve power generation revenue; In the field of scientific research, it can also be used for defect analysis and performance testing of new photovoltaic modules, assisting in the development of new materials and process optimization.

At present, the photovoltaic industry is in a critical stage of high-quality development, and component quality and reliability have become the core competitiveness of enterprises. The launch of Suzhou LAILX portable EL detector LXG30 not only provides an efficient and accurate solution for photovoltaic detection, but also promotes the popularization and upgrading of photovoltaic defect detection technology. In the future, LAILX in Suzhou will continue to focus on user needs, iterate product functions, expand the application scenarios of EL detection technology, provide more professional and comprehensive quality testing tools for global photovoltaic enterprises, and help the photovoltaic industry achieve more efficient and sustainable development.
