I-V curve tracing

  • Quick performance diagnosis — instantly shows whether a PV asset runs at its expected parameters or has losses.
  • Fault detection — reveals defective cells, poor connections or shading effects.
  • Optimisation and maintenance — plan interventions for maximum asset efficiency.
Inspection drone with thermal camera

Drone inspections

  • Rapid aerial inspection — scans large areas quickly and captures real-time data on system condition.
  • Thermal fault detection — IR vision finds hotspots caused by defects, shading or electrical issues.
  • Efficient maintenance planning — targeted interventions, less downtime.
