Airborne PV EL/PL Detector
Airborne EL/PL inspection Equipped with a hyperspectral imaging system and advanced AI large-model algorithms, the device can automatically identify defects such as cracks, broken grid lines, and short circuits.
  • CHNSpec EP-DU/EP-NU Series Airborne EL/PL Detectors are engineered for drone inspections of large-scale photovoltaic plants. Fully compatible with the DJI M350/M400 drone platforms, they feature a lightweight design, comprehensive detection modes, and intelligent, user-friendly controls—significantly enhancing the efficiency, accuracy, and operational flexibility of airborne PV inspections across various precision requirements and project scales.

    1. All-Mode, All-Weather Operation for Unrestricted Inspections: Supports nighttime EL / daytime EL / daytime PL full-mode detection, completely eliminating interference from ambient light such as sunlight, moonlight, starlight, and artificial lighting. This enables truly stable 24/7 all-weather operation, delivering clear inspection results whether for routine daytime batch inspections or precise nighttime troubleshooting, and adapting to complex outdoor climatic conditions.
    2. Lightweight Design for Efficient Deployment: Features an ultra-lightweight design that minimizes the payload on the drone. This facilitates quick assembly/disassembly, transportation, and on-site deployment, significantly enhancing operational mobility and efficiency.
    3. Intelligent and User-Friendly Operation: Equipped with a remote controller featuring an integrated high-brightness screen, supporting real-time image preview and flexible parameter adjustment for an intuitive user experience. It also features a multi-language operation interface, greatly lowering the skill barrier and improving on-site workflow fluency.
