Mountain PV, mudflat PV and large ground power stations have large areas and complex terrain, so it is difficult for traditional manual inspection to cover every module. When encountering situations such as abnormal power generation, lightning strikes, strong winds and hail, construction trampling, transportation damage, etc., relying on manual row by row inspection is time-consuming and labor-intensive, and it is also easy to miss local problems. Drone inspection has therefore received attention, but ordinary drones can only see the appearance and cannot directly detect internal defects such as hidden cracks and broken grids, which limits their effectiveness.

At present, there are several types of unmanned aerial vehicle related detection schemes. Ordinary aerial drones are suitable for viewing the overall situation, obstruction, dust accumulation, and damaged glass of the array, but they cannot deeply determine internal defects of the components. Infrared drones can detect some hot spots, but they are greatly affected by temperature, wind speed, and sunlight, and may not be sensitive to early hidden cracks. There are also some conceptual plans that have been widely promoted, but their actual implementation is significantly limited by factors such as battery life, payload, data processing, and on-site environment.

The LAILX drone EL detection LXH210 in Shanghai combines drone inspection and EL detection ideas, making it more suitable for rapid screening of abnormal areas in large-scale power plants. It can help the operations team narrow down the scope of investigation from a massive number of components, first finding suspicious strings or components, and then arranging manual review, IV testing, or ground EL confirmation. Compared to blind on-site inspections, this method can improve manual efficiency and is more suitable for regular physical examinations and post disaster inspections of large power plants.

The suitable scenarios for LXH210 are quite clear. For example, if the power generation in a certain area of a mountainous power station is low, unmanned aerial vehicles can be used to quickly screen for abnormal locations; After hail and strong winds, it is possible to determine which areas may be damaged; During the acceptance of large-scale projects, it can assist in discovering batch installation issues; In after-sales disputes, it can also provide a basis for judging the status of components. It is not a replacement for all traditional tests, but rather makes large-scale initial screening faster, making subsequent tests more targeted.

From the trend, photovoltaic inspection will move from manual to integrated space, sky, and earth. Satellites and monitoring platforms have detected overall abnormalities, drones are responsible for regional screening, ground IV and EL are responsible for confirmation, cleaning robots and operations teams are responsible for handling, and the entire process will become increasingly smooth. A single device is difficult to solve all problems, and brands that can form a combination solution have more advantages. LAILX covers portable IV testers, daytime EL detectors, photovoltaic cleaning robots, insulation grounding comprehensive testers, and unmanned aerial vehicle EL detection, forming a relatively complete layout around power plant detection, diagnosis, and maintenance. This is also an important reason why it has attracted attention in the field of photovoltaic operation and maintenance equipment.

When choosing drone EL detection, attention should be paid to the actual imaging effect, ability to pass through complex terrain, data processing efficiency, report output capability, and after-sales support, rather than just looking at flight parameters. The ultimate goal of power station inspections is to reduce losses and improve safety, rather than simply pursuing novelty in equipment. LXH210 is suitable for power stations with large areas, complex terrain, and high manual inspection costs, as well as for operation and maintenance teams who want to improve their digital inspection capabilities. After entering the stage of refined operation and maintenance of photovoltaics, whoever can detect problems faster will be able to grasp the benefits and risks more steadily.
