Solar Panel PV EL Electroluminescence Inspection Camera Payload for DJI M400 Drone

The Solar Panel PV EL Electroluminescence Inspection Camera Payload is a next-generation drone-mounted inspection solution designed for utility-scale photovoltaic (PV) power plants. Equipped with a high-sensitivity InGaAs SWIR sensor, the system enables Daytime Electroluminescence (Daytime EL) inspection, allowing operators to perform high-resolution EL imaging without waiting for nightfall or using dark environments.

Designed specifically for DJI Matrice 400 and DJI Matrice 350 UAV platforms, the drone mounted EL inspection camera significantly improves the efficiency of large-scale solar farm inspections by combining drone mobility with advanced EL imaging technology. It accurately detects hidden defects inside photovoltaic modules, including micro-cracks, broken cells, finger interruptions, inactive cells, PID (Potential Induced Degradation), soldering defects, and other internal cell failures that are invisible during standard visual inspections.

Unlike traditional EL inspection systems that require nighttime operation, the PV EL camera supports Daytime EL, Daylight Electroluminescence, and conventional Night EL inspection modes, providing flexible inspection capabilities for different operating conditions. Real-time image preview, GPS positioning, and automatic defect location recording further simplify field inspections and maintenance planning.

With its lightweight payload design, it is ideal for rapid deployment over utility-scale solar farms, rooftop PV systems, and large photovoltaic power plants, delivering faster inspections, lower labor costs, and higher inspection efficiency.
