Unmanned Aerial Vehicle EL Tester
The drone EL tester is a specialized device used to test photovoltaic modules, such as solar panels, combining drone technology and electroluminescence (EL) imaging technology. By using drones equipped with EL detection equipment, it is possible to efficiently and quickly detect defects in large-scale photovoltaic power plants.

Major function

Electroluminescence imaging:
EL imaging applies current to photovoltaic modules, causing them to emit near-infrared light, and captures luminescent images using a high-sensitivity camera.
Identify internal issues such as hidden cracks, broken grids, fragments, welding defects, etc.
Drone carrying:
Drones can fly flexibly, adapt to complex terrain, cover large areas, and are particularly suitable for large photovoltaic power plants.
Reduce the time and cost of manual testing and improve efficiency.
Automated detection:
Combining AI and image processing technology, automatically analyze EL images, identify defects, and generate reports.
