Drone-Based, AI-Assisted Electroluminescence Testing for Utility-Scale PV Plants

Your Benefits of Drone-Based Electroluminescence Inspections by TÜV Rheinland

Drones flying over solar cells
  • Efficient Inspection of Utility-Scale PV Plants

    Autonomous drone operations enable fast inspection of large photovoltaic installations, reducing on-site effort, inspection duration and operational disruption.
  • Accurate Detection and Classification of Defects

    AI-supported analysis of high-resolution EL data allows precise identification and categorization of module defects, including hail damage, microcracks and degradation effects.
  • Detailed and Actionable Reporting

    Module-level defect mapping provides transparent insights into the condition of PV assets and supports targeted maintenance, repair and replacement planning.
  • Economically Efficient Inspection Approach

    Automated data acquisition and analysis significantly reduce inspection time and associated costs, making EL inspections feasible for a wide range of project sizes and lifecycle applications.
  • Integrated Expertise and Laboratory Support

    In addition to field inspections, TÜV Rheinland offers access to accredited laboratories and technical experts. Optional sample-based laboratory testing supports deeper analysis of identified defects and helps determine underlying root causes when required.
