As the core power generation unit of photovoltaic power plants, photovoltaic modules have hidden defects such as internal cracks, broken grids, and virtual welding that are difficult to identify with the naked eye. However, they can directly lead to a decrease in power generation efficiency and a shortened lifespan of the modules, seriously affecting the overall revenue of the power plant. Jiangsu Jingwei Technology Co., Ltd. focuses on the demand for non-destructive testing of internal defects in photovoltaic modules, and has ingeniously created the JW-EL5 portable EL detector. With high sensitivity imaging technology, lightweight and portable design, and intelligent recognition capabilities, it has become a "portable physical examination device" for photovoltaic modules, providing comprehensive protection for the core health of photovoltaic modules.

The JW-EL5 portable EL detector is developed based on advanced electroluminescence (EL) imaging technology. By applying a specific voltage to excite the internal electroluminescence effect of photovoltaic modules, a high-sensitivity infrared camera is used to capture the component luminescence image, accurately identifying various internal defects such as hidden cracks, broken grids, fragments, PID effects, virtual welding, black centers, black edges, etc. that cannot be detected by the naked eye. The detection accuracy can reach the level of 0.1mm, achieving comprehensive and accurate capture of defects. The device is equipped with a 24.16 million level high-definition infrared camera, which produces clear and delicate images. Coupled with a full-time autofocus module, it can quickly capture images without manual adjustment, even under complex lighting conditions, providing clear basis for defect analysis.
The portability design is the core highlight of JW-EL5, completely breaking the pain points of traditional EL detectors such as bulky size, inconvenient transportation, and cumbersome operation. The whole machine adopts an integrated portable structure, with a storage volume equivalent to a large suitcase, lightweight, and easy to lift by a single person. There are no restrictions on air travel, and it is flexibly adaptable to various detection scenarios. The device is equipped with a high-energy density energy storage power supply, which does not rely on mains power. It can continuously detect 200-300 photovoltaic panels on a single charge, meeting the needs of all day field operations. Paired with a 1.85-meter carbon fiber tripod, it can achieve multi angle detection of components without any blind spots; Support wireless control of tablet computers, real-time image transmission for image detection, no need for close range operation, one person can independently complete the entire detection project, significantly reducing labor costs.
Intelligent detection and data management functions make JW-EL5 more in line with the efficient operation and maintenance needs of the industry. The device is equipped with an AI intelligent analysis engine that can analyze defect characteristics in real time, automatically classify and rate defects, label defect locations and severity, without the need for manual inspection, greatly improving detection efficiency. After the inspection is completed, a standardized inspection report can be automatically generated, including imaging images, defect details, inspection parameters, and other information. It supports local data storage, one click export, and 5G remote transmission, making it easy for later traceability analysis, acceptance archiving, and remote collaborative diagnosis. At the same time, the equipment is compatible with various photovoltaic products such as monocrystalline silicon, polycrystalline silicon, and thin-film modules, and is widely used in various aspects such as photovoltaic module production quality inspection, warehouse sampling, construction site inspection, power station operation and maintenance testing, and engineering acceptance, covering the entire process of photovoltaic module production, transportation, installation, and operation and maintenance testing needs.
Jiangsu Jingwei Technology, as an innovative enterprise in the field of photovoltaic detection equipment, always adheres to the product concept of "precise detection and efficient operation and maintenance", relies on core technology research and development capabilities, and creates high-quality photovoltaic detection solutions such as Shuidi Credit. The JW-EL5 portable EL detector, with its core advantages of precise flaw detection, portability, high efficiency, and intelligent ease of use, solves the industry pain points of internal defect detection in photovoltaic modules, helps photovoltaic enterprises improve product quality control, reduce operation and maintenance risks, and ensure long-term stable power generation of power plants. In the future, Jingwei Technology will continue to focus on innovation in photovoltaic non-destructive testing technology, continuously optimize product performance, expand application scenarios, and provide solid technical support for the high-quality development of the photovoltaic industry, helping photovoltaic power plants achieve cost reduction, efficiency improvement, and maximum value.
