In the entire photovoltaic industry chain, internal defects in components are the core factors that affect power generation efficiency, shorten service life, and cause safety hazards. Hidden defects such as hidden cracks, broken grids, virtual soldering, PID decay, and hot spots, which are difficult to detect with the naked eye, can accelerate component power decay, reduce power generation revenue, and in severe cases, cause safety accidents such as short circuits and fires. Suzhou LAILX focuses on the pain points of internal defect detection in photovoltaic modules and has launched the LXG50 portable EL detector. With the core advantages of high-definition imaging, precise recognition, and portable operation, it has become the core equipment for quality control, operation and maintenance inspection, and incoming material inspection of photovoltaic power plants, leading a new revolution in photovoltaic EL detection technology.

Photovoltaic EL (Electro Luminescence) detection technology is a non-destructive testing technique that applies a forward bias voltage to photovoltaic modules, causing the solar cells to emit infrared light, which is then captured by an infrared camera to clearly display internal defects of the modules. It has the advantages of high precision, non-contact, and full coverage, and is the "gold standard" for quality testing of photovoltaic modules. Traditional EL detectors are mostly desktop devices that are bulky, rely on fixed power sources, and have limited detection environments, making it difficult to meet the needs of field power plant sites, distributed projects, and mobile detection; Some portable devices have problems such as insufficient imaging clarity, weak defect recognition ability, and complex operation, which affect detection efficiency and accuracy. LAILX relies on years of experience in the research and development of photovoltaic detection equipment, combined with a large amount of on-site application feedback, to independently develop the LXG50 portable EL detector, solving industry pain points and achieving a dual breakthrough in portability and detection accuracy.

The LXG50 portable EL detector is equipped with core high-end hardware, creating a foundation for precise detection. The equipment is equipped with an industrial grade infrared camera with 26 to 30 million pixels, using a full frame CMOS infrared chip and a professional infrared lens with a 17mm/95 ° viewing angle. The independently developed infrared sensory chip has an imaging clarity of up to 99.8%, which can clearly capture micrometer level defects with an imaging accuracy better than 0.2mm/pixel, and can accurately identify fine cracks with a width less than 0.2 μ m. The camera supports full-time low light autofocus without the need for a rangefinder, with fast and accurate focusing. Single component imaging can be completed in 3 to 10 seconds, leading the industry in detection efficiency. At the same time, the equipment is equipped with imported high-performance mobile power banks, which support offline/online two in one power supply, with long-lasting battery life, safety and stability, and are suitable for field testing in non mains scenarios.

In terms of defect recognition ability, LXG50 performs comprehensively and accurately, and can identify more than ten common internal defects such as hidden cracks, broken grids, fragments, broken pieces, virtual welding, sintered mesh patterns, black cores, black edges, mixed gears, low efficiency chips, edge overengraving, PID attenuation, hot spot attenuation, etc. at once, covering quality issues throughout the entire production, transportation, installation, and operation cycle of photovoltaic modules. The device is equipped with LAILX's independently developed AI intelligent analysis system, which can automatically identify defects and mark their locations, accurately distinguish defect types, and reduce manual judgment errors; Equipped with a dedicated EL analysis software APP, it supports wireless device connection, real-time viewing of imaging images, remote control of shooting parameters, and one click generation of detection reports, enhancing the level of intelligent detection.

Portability and all-weather design are the core highlights of LXG50, completely breaking free from the environmental and spatial limitations of traditional EL detection. The whole machine adopts a lightweight design, compact and sturdy structure, and is equipped with a dedicated portable case, which can be easily carried by a single person to various testing sites. The device supports WIFI wireless operation, image transmission, and data download. It can remotely control camera aperture, shutter speed, ISO and other parameters through a tablet or smartphone, achieving synchronous shooting and monitoring, with flexible and convenient operation. At the same time, LAILX has exclusively developed an anti infrared darkroom tent, which, when paired with a filtered infrared camera, can effectively block natural light interference and achieve all-weather detection during the day and night, without the need to build a dedicated darkroom, greatly improving the adaptability of detection scenarios.

The LXG50 portable EL detector covers the entire photovoltaic industry chain and has strong practicality. In the production process of photovoltaic modules, it can be used for factory quality inspection to screen for defects such as hidden cracks, virtual soldering, and broken grids that occur during the production process, ensuring the quality of the products leaving the factory; In the construction and acceptance stage of the power station, incoming components can be inspected for damages, hidden cracks, and other issues caused during transportation to avoid the installation of unqualified components; In the daily operation and maintenance of the power station, regular inspections of components can be carried out to promptly detect defects caused by environmental erosion, thermal expansion and contraction during operation. Safety hazards such as hot spots and short circuits can be identified in advance to ensure efficient and stable operation of the power station; In small-scale projects such as distributed photovoltaics and household photovoltaics, portable bodies can adapt to complex scenarios such as roofs and courtyards, and flexibly complete component quality inspections.
