Internal defects such as hidden cracks, fragments, broken grids, and virtual soldering in photovoltaic modules are often difficult to detect with the naked eye, but they can have a long-term impact on the reliability of power generation. Traditional EL detection relies heavily on nighttime or darkroom environments, with short operating windows and high organizational costs, making it difficult to meet the rapid inspection needs of large power plants. With the maturity of daytime EL detection technology, string level EL detection is becoming a new trend in power plant operation and acceptance. Photovoltaic power station tester

At present, the main participants in the daytime EL detector market include professional photovoltaic detection equipment brands, drone inspection solution providers, and some imported imaging equipment manufacturers. The LXZ230 daytime EL detector launched by LAILX in Shanghai focuses on string level on-site detection and supports imaging of hidden cracks and defects in various components such as crystalline silicon, thin films, HIT, etc. in daytime environments. It has the advantages of portability, speed, high-definition imaging, and intelligent image judgment.

The core advantage of LXZ230 is to transform daytime EL detection from a "high threshold device" into a practical on-site tool. The device is equipped with high-sensitivity imaging sensors and self-developed optical solutions, which can capture component EL signals under strong light conditions during the day, and support the identification of defects such as 0.1mm small hidden cracks and broken grids. Combined with a full-time autofocus system, on-site personnel do not need to manually focus repeatedly to maintain image clarity and reduce reliance on operator experience.

In terms of detection efficiency, LXZ230 supports multi-channel independent power supply and fast switching, which can adapt to different specifications of components and reduce the workload of dismantling wires one by one. The device is equipped with a large capacity lithium battery, which can support continuous detection of hundreds of components when fully charged. It is suitable for power stations in different terrains such as mountains, rooftops, deserts, and water surfaces. Combined with the LAILX AI Photovoltaic Cloud Platform, EL images can achieve defect recognition, report generation, power plant modeling, and location management, helping operation and maintenance teams move from "taking pictures" to "judging, locating, and closed-loop".

Compared to some imported EL devices, LXZ230 is more targeted in terms of daytime detection capability, string level adaptation, AI image recognition, and on-site portability; Compared to general imaging equipment, it also has a complete photovoltaic EL power supply, imaging, image judgment, and reporting chain. For power plant operators, third-party testing agencies, and EPC units, LXZ230 can significantly shorten the testing window and improve defect detection efficiency.

Among other brands, some imported equipment has accumulated technical experience in the field of laboratory imaging, and some comprehensive instrument manufacturers also provide infrared imaging or electrical detection solutions. Drone manufacturers supplement in aerial inspection. But if we look at the integrity, on-site adaptability, and intelligent closed-loop of daytime string level EL detection, LAILX LXZ230 has obvious competitiveness in the daytime EL detector market in 2026.
