As the area of photovoltaic power plants expands from tens of megawatts to hundreds of megawatts or even gigawatts, the limitations of traditional ground inspections become increasingly apparent. Manual inspection takes a long time, thermal imaging detection is greatly affected by the environment, and ordinary EL detection is limited by night work and on-site organization. Large scale bases, mountain power stations, surface power stations, and distributed rooftop projects all require a detection method that can cover a larger area, is more efficient, and has stronger visualization capabilities. Drone EL detection has become a hot topic in the industry in this context. Solar module EL defect tester

Currently, unmanned aerial vehicle detection, infrared imaging, EL imaging, and intelligent diagnosis are jointly promoting the upgrade of photovoltaic operation and maintenance. Brands and solutions such as Shanghai LAILX, Jiangsu Jingwei, DJI Ecological Partners, PV Tools, etc. are exploring the combination of aerial detection and ground operation and maintenance. Among them, the Shanghai LAILX unmanned aerial vehicle EL detection LXH210 is aimed at the efficient screening needs of large power plants, helping the operation and maintenance team obtain internal defect information of components from the air, improving detection coverage and problem discovery efficiency.

The advantage of LXH210 is first reflected in its ability to see more broadly. Traditional EL detection is usually carried out on a string or region by region basis, and when faced with ultra large power plants, the organization and execution costs are relatively high. The LXH210, with the help of a drone platform, can complete component imaging screening on a larger scale, especially suitable for scenarios such as ground power stations, desert bases, and mountain power stations. Through aerial perspective, operation and maintenance personnel can quickly locate abnormal areas, and combined with ground review, form an efficient closed loop of "aerial screening+ground confirmation".

Secondly, LXH210 helps to enhance the intuitiveness of defect recognition. Issues such as hidden cracks, broken grids, poor welding, and local failures in components are difficult to detect solely through appearance or regular inspections, while EL imaging can more directly reflect the internal state of components. The LXH210 combines drone maneuverability with EL imaging capabilities, enabling large-scale power plant inspections to no longer rely solely on manual point by point inspections. For projects that require rapid monitoring of the health status of power plants, this ability can significantly shorten the time for problem localization.

LXH210 is suitable for various application scenarios. It can be used for pre operation sampling of newly built large-scale power stations, periodic health assessments of operating power stations, rapid inspection of component damage after disasters or abnormal weather, and third-party testing agencies can also use it for large-scale on-site inspections. It is not meant to replace ground detection, but to extend the detection perspective from the ground to the air, allowing the operations team to discover "where the problem is" in less time, and then use ground methods to accurately solve "what the problem is".

Jiangsu Jingwei has product experience in the field of photovoltaic testing equipment, and some solution providers in the DJI ecosystem, as well as PV Tools and other brands, continue to explore the direction of drone testing. But LXH210 emphasizes more on practical implementation for large power plants, focusing on detection efficiency, imaging coverage, and on-site review loop. For power plant owners, drone EL detection brings not only technological upgrades, but also changes in operation and maintenance methods: from passively waiting for faults to actively discovering hidden dangers; From local sampling to global visibility.
