Impressions of onsite inspections
The smart inspection concept for any pv plant worldwide
Aerial pv inspection combines and automates classic and preventive inspections of solar power plants with image based methods like thermography and electroluminescence measurements, IV-curve recording by day and night, isolation issues detection, serial number scan, and geography data referencing. To this end we employ tripod- and drone-based sensor systems, providing a cost-effective check-up by full plant screening or systematic sampling. EL measurements offer a comprehensive and qualitative assessment on cell level and thus represent the tower of strength of the aepvi concept.
Electroluminescence-Analysis and combined Measurements On-Site by spezialised Tripod- and UAV-Systems
Inspection by remotecontrolled Measurement Devices and Power Supplies like AePVI Switch
Electroluminescence Measurement, i.e. without Dismounting and Transport of Solar Modules
by Electroluminescence Measurement or Systematic Sampling with specialized UAV- and Tripod-Systems like AirLabONE and SlideAirONE
Measurements in One Step: Additional IV-Curve-Measurements by Day and Night, or Isolation Checks
Electroluminescence Measurement for any PV-Plant Size worldwide, up to 400 Pictures per Hour with AirBridgeONE
Dependent on Request and Failure Type
Impressions of onsite inspections
Solar Panels produce electricity during the day, but in complete darkness if connected to a power supply, they emit radiation in the near-infrared light spectrum, which is not visible by the naked eye.
High resolution Electroluminescence (EL) images look similar to X-ray images. Active cells appear bright to grey while inactive or damaged cells appear dark to black. The grey scale seen in the images allows the cause and the amount of damage to be directly determined onsite.
Therefore specific solar panels can be selected for further laboratory tests.
With this image based qualitative measurement, damages caused by mechanical stresses, like transportation, installation, hail, overload from snow or defective by-pass diodes from overvoltage can be quickly detected. Moreover deterioration, broken cell, interconnections, cracked cells and malfunctioning panels and strings can also be recognized.
Aerial EL testing is the most cost efficient method currently on the market for the clear and early detection of PID (Potential Induced Degradation) affected solar systems.
This testing method can furthermore be used to verify the recovery of PID affected systems and also enable the reproduction of sytem documentation from false or non-exisentent string plans.
