Hidden defects such as internal cracks, virtual welding, broken grids, PID attenuation, and black core fragments in photovoltaic modules cannot be identified by the naked eye or conventional multimeters. However, they are the core causes of annual power generation attenuation and hot spot ignition in power plants. EL electroluminescence imaging detection is currently recognized as the core method for non-destructive defect screening of modules in the industry. Traditional portable EL detectors generally have shortcomings such as cumbersome focusing, only detectable at night, limited wired operation, relying on manual visual inspection for defects, and insufficient imaging clarity. The on-site detection efficiency of mountainous areas, rooftops, and distributed scattered power stations is extremely low. Suzhou Laikesi New Energy (LAILX) relies on years of experience in optical imaging and AI algorithm research and development to launch the LXG50 portable EL detector. It is equipped with four core technologies: the eighth generation full-time autofocus imaging system, wireless remote control, AI intelligent defect recognition, and all-weather detection. The lightweight body is suitable for outdoor operations in all scenarios, achieving fast, clear, and automated screening of photovoltaic module defects. It widely serves various photovoltaic detection scenarios such as component factory quality inspection, power station acceptance, operation and maintenance inspection, and transportation loss assessment.

The most innovative technological breakthrough of LXG50 in the industry is LAILX's self-developed eighth generation full-time autofocus optical system, which completely solves the industry pain points of manual ranging and local focus blur in traditional EL devices. The device is equipped with a 26 million pixel professional infrared imaging camera and a built-in global autofocus chip. Whether it is a horizontal array, a tilted roof component, or a high-altitude mountain power station, it can achieve instant moving and shooting, uniform and clear imaging of the entire picture, without the need for manual adjustment of lens distance and aperture parameters, greatly reducing the time for single component shooting and debugging. Equipped with an original factory anti infrared shading tent and a dedicated filter lens, it achieves 24/7 seamless detection. In strong light environments during the day, there is no need to wait for nighttime shutdown. The operation and maintenance team can synchronously complete EL defect imaging during daytime inspections, breaking the time limit of traditional EL equipment that can only operate at night. The daily detection coverage area of megawatt level power plants has been increased by more than twice, greatly optimizing the efficiency of operation and maintenance scheduling. The whole machine is equipped with a lightweight program-controlled DC detection power supply. The total weight of the entire equipment is only 5 kilograms. A single person can carry a tripod, storage box, and a complete set of accessories to various remote work sites. The assembly and debugging can be completed in five minutes without the assistance of a professional electrician, and the machine can be turned on for testing.

The wireless interconnection remote control design greatly improves the safety and convenience of on-site operations. The LXG50 is equipped with a 2.4G high-speed WIFI wireless transmission module, which supports synchronous connection of multiple devices such as mobile phones and tablets. Operation and maintenance personnel can remotely control camera shutter, exposure, and contrast parameters through the APP from a safe distance, and view infrared imaging images in real time synchronously without the need for close contact with live component strings, avoiding safety hazards in high-altitude and high-voltage operations. The device supports dual terminal synchronous control, with one device controlling the shooting and the other device monitoring the imaging effect in real-time. The multi person collaborative inspection mode is suitable for large-scale centralized power plant batch testing. Programmable power supply synchronous wireless linkage control, one click adjustment of power on current parameters through mobile APP, adapted to different types of component detection needs such as monocrystalline silicon, polycrystalline silicon, double glass, half sheet, thin film, perovskite, etc., without frequent replacement of power supply wiring, simplifying on-site operation process. The entire equipment is powered by lightweight lithium batteries and comes with a visual power display screen. When fully charged, it can support continuous outdoor monitoring throughout the day, eliminating the need to carry bulky external power supply equipment in outdoor scenarios without mains power.

The built-in AI intelligent defect automatic recognition algorithm is the core function of LXG50 to reduce costs and increase efficiency. Unlike the inefficient mode of manually marking defects frame by frame after imaging with traditional equipment, the device can automatically recognize more than ten common component defects such as hidden cracks, virtual welding, broken grids, fragments, mixed low efficiency chips, PID black edges, sintered mesh, etc. in the imaging image, automatically mark defect coordinates, classify and count defect sizes and quantities, and automatically distinguish minor defects, moderate attenuation defects, and severe scrap defects without the need for inspection personnel with years of defect recognition experience. Zero based operators can also accurately complete screening work, and the defect recognition accuracy can reach over 98%. The workload of manual image reading is reduced by 60%. The equipment is equipped with a complete project management system, which supports entering the name of the power station, array number, and component barcode. The captured images are automatically bound with corresponding component information, and the images come with watermarks to identify project parameters. The PC is equipped with professional analysis software, which can import all EL imaging images in batches and automatically generate standardized detection reports. The reports include defect distribution maps, defect proportion statistics, and a list of faulty components. They support one click PDF export and can be directly used for project acceptance and preparation of operation and maintenance rectification plans.

The rigorous environmental adaptation design enables LXG50 to cover all types of photovoltaic operation scenarios, with equipment working range covering -20 ℃ to 50 ℃. The dust-proof and waterproof protective structure can adapt to harsh outdoor environments such as desert sandstorms, plateau low temperatures, southern plum rain high humidity, coastal salt spray corrosion, etc; The tripod is made of high-strength alloy material, which is lightweight and stable against wind. It can be installed stably on mountains, slopes, and uneven roofs. The testing object covers all categories of photovoltaic modules, whether it is bare modules that have not been installed in the factory, full box modules that have been transported and delivered, or rooftop, ground, agricultural photovoltaic complementary, and fishery photovoltaic complementary array modules that have been connected to the grid for operation, they can all be non-destructive tested; It supports both independent imaging of individual components and large-scale synchronous scanning imaging of entire rows and strings. The video continuous scanning function is suitable for fast large-scale census operations.

In diversified industry implementation scenarios, LXG50 plays an irreplaceable role in detection value. Photovoltaic module production enterprises use full inspection of production lines to screen out internal defective components in advance and reduce terminal power station complaints and losses; Rapid on-site inspection of component logistics arrival, accurate determination of hidden cracks and damages caused by transportation collisions, and division of responsibilities between supply and demand parties; During the completion and acceptance stage of the new photovoltaic power station, a third-party testing agency conducts equipment sampling of the entire array to identify internal damage to components caused by installation and handling, ensuring the quality of project installation; Regular inspections of the daily operation and maintenance of existing power stations are conducted to locate internal defective components in advance, avoid long-term hidden cracks that may cause hot spots and significant power attenuation, and improve overall power generation; At the same time, it is suitable for photovoltaic laboratories and new battery research and development institutions, used for imaging analysis of the internal microstructure of perovskite and stacked components, supporting the research and verification of cutting-edge photovoltaic technology.
