Drone-based thermographic inspection allows for fast and precise detection of defects in solar panels and other electrical installations using high-resolution thermal cameras and automated flight paths. Drones can survey large areas quickly without stopping system operation and provide much more detailed data than manual inspections. This method significantly reduces risks to personnel, improves maintenance planning, and enables early detection of issues that could impact performance and safety.
Hot spots, damaged cells, and module delamination
Soiling/dust accumulation, activated bypass diodes, underperforming modules
Disconnected strings, reverse polarity, inverter or DC/AC line issues
Shading, vegetation overgrowth, and other external interferences
Data Volume & Accuracy – Drones capture more anomalies with high temperature sensitivity
Detailed Reports – Complete list of thermal anomalies and losses with recommended corrective actions
No System Downtime – Inspections are performed while the system is fully operational, avoiding production losses
Speed – Up to 10 minutes per 1 MW, compared to 2–5 hours for manual inspections
Safer Process – Eliminates work on rooftops, live circuits, or hazardous areas
Historical Data – Repeat flights allow tracking of panel degradation and data-driven maintenance decisions
