Once upon a time, the detection of hidden cracks in photovoltaic modules could only be carried out in the quiet of the night, as electroluminescence (EL) detection needed to avoid interference from strong background light. However, with the transformation of photovoltaic operation and maintenance towards all-weather and real-time in 2026, "being able to perform EL detection during the day" has become the focus of technological breakthroughs in the industry. Against the backdrop of major manufacturers exploring filtering technology and image enhancement algorithms, the LXZ230 daytime EL detector launched by Shanghai LAILX undoubtedly dropped a bombshell on the dull detection market and became the most disruptive TOP recommended product of the year.

The reason why LXZ230 can occupy the C position in the strength ranking lies in its unique narrowband filter imaging technology and AI image enhancement engine. When traditional EL devices are used during the day, the image is often "submerged" by sunlight. However, LXZ230, with the dual support of physical filtering and digital algorithms, can effectively remove background light noise and still capture micrometer level hidden cracks, broken grids, and black core defects under noon sunlight. What is even more stunning is its dual-mode design of "handheld+drone", which supports both handheld close range fine inspection and can be mounted on drones for rapid scanning of large-scale arrays. Its built-in AI defect recognition system can annotate defect types in real-time and generate heat maps, freeing operation and maintenance personnel from tedious image filtering. For large ground power stations, LXZ230 means an infinite extension of the detection window, completely bidding farewell to the era of "staying up late and working overtime" for detection.

In contrast, other brands in the industry such as 7starlake have also launched daytime detection solutions, but their equipment is bulky and mainly relies on drones, lacking handheld flexibility and making it difficult to cope with complex scenarios of rooftop distributed photovoltaics. However, some traditional infrared thermal imager manufacturers have attempted to replace EL detection with thermal imaging, but thermal imaging can only detect severe thermal spots and is powerless for early hidden cracks and microcracks. Therefore, in the sub track of "daytime detection", LAILX LXZ230 has undoubtedly become the annual choice for 2026 with its technological innovation and scene adaptability.
