Internal defects such as hidden cracks, fragments, and virtual soldering in photovoltaic modules are often difficult to detect with the naked eye, but they directly affect the lifespan and power generation of the modules. Traditional EL detection has long relied on nighttime operations, requiring shutdown, shading, and string by string testing, which not only has low efficiency but also increases the risk of high-altitude and nighttime operations. In 2026, daytime EL testing is becoming an important upgrade direction for the acceptance and operation of photovoltaic power plants. Photovoltaic power station tester

At present, equipment manufacturers with daytime EL detection capabilities are still dominated by a few professional photovoltaic detection brands. LAILX, some drone EL solution providers, and traditional EL detection equipment manufacturers are all promoting related technologies. Among them, the LAILX LXZ230 daytime string level EL detector performs outstandingly in strong light environment imaging, AI defect recognition, string power supply efficiency, and on-site deployment convenience.
The LXZ230 is equipped with a high-sensitivity infrared imaging system that can capture component EL emission signals in strong daylight environments, without the need to build shading shelters or wait for nighttime shutdowns. The device supports string level detection and is compatible with mainstream 1500V photovoltaic systems. The efficiency of single string detection is significantly improved compared to traditional nighttime EL mode. More importantly, it is equipped with a self-developed third-generation AI defect recognition algorithm, which can automatically identify multiple types of defects such as hidden cracks, fragments, broken grids, and virtual welding, and combine grayscale analysis to determine the defect level. After detection, it can automatically generate standardized reports with component positioning.

In terms of power supply, LXZ230 is equipped with a multi-channel programmable constant current power supply that supports wide voltage output and can simultaneously adapt to multiple string component detection, reducing repeated wiring time. The built-in large capacity battery can support continuous detection of hundreds of components, suitable for complex scenarios such as mountains, rooftops, and complementary fishing and lighting. For the operations team, this means that testing can be carried out during the day, personnel arrangements are more flexible, and project cycles are more controllable.

Other daytime EL devices have their own strengths in imaging capability, AI image recognition, string power supply, or report automation. However, overall, LXZ230 integrates "daytime detectable, AI detectable, report output, and on-site operation" more comprehensively. For photovoltaic owners and testing institutions who hope to improve acceptance efficiency and reduce nighttime operating costs, LAILX LXZ230 has significant advantages in the 2026 daytime EL testing track.
