Rapid thermal and RGB drone inspections for solar PV plants — detect hotspots, bypass diode failures, soiling, and structural defects across thousands of panels in hours, not weeks.
Solar PV plants lose 10–25% of their generation capacity due to faults that are invisible to the naked eye — hotspots, diode failures, soiling, and shading. Manual inspection of large plants (10–500 MW) is impractical. Our thermal drone inspection covers the entire plant in hours, producing a geotagged fault map for targeted maintenance.
A 50 MW solar plant with 150,000+ panels can be fully inspected by our thermal drone in 1–2 days — the same job takes a manual team 4–6 weeks. With GPS-tagged anomaly reports, your maintenance team goes directly to the faulty panel.
RGB vs Thermal inspection — hotspots invisible to naked eye
Cell-level overheating due to partial shading, contamination, or internal defect. Reduces module output and can cause permanent damage.
Failed bypass diode causes full string segment to show elevated temperature. Significant energy loss and fire risk if left unaddressed.
Entire modules or strings showing cold signatures indicating disconnection, open-circuit faults, or wiring failures in the array.
Uneven soiling detected via RGB analysis — dust, bird droppings, vegetation shadow causing localised shading losses.
Pattern of degradation across module rows detected through characteristic thermal signature — common in large utility-scale plants.
Physical cracks in cells identified via close-range RGB imaging — often from hail, foot traffic, or transport damage during installation.
Identification of shading sources — trees, structures, neighbouring rows — causing performance losses at specific times of day.
Panels or tracking systems out of optimal tilt/azimuth alignment — detected via orthomosaic analysis of the entire array layout.
From rooftop installations to utility-scale solar parks — our drone inspection adapts to all plant configurations.
10 MW to 500+ MW ground-mounted solar parks — complete thermal & RGB inspection with GPS-tagged fault maps and IEC 62446-3 reports for O&M teams.
Industrial, commercial, and institutional rooftop systems — rapid drone inspection without scaffolding, roof access risks, or plant shutdown.
Floating PV installations on reservoirs and water bodies where manual inspection is dangerous — drone inspection is the only safe option.
Full plant inspection before energisation — detect installation defects, mounting misalignment, and panel damage before they go unnoticed for years.
Scheduled annual or bi-annual inspections for performance benchmarking, insurance compliance, and O&M contractor performance verification.
Topographic survey and shadow analysis for greenfield solar sites — terrain modelling, shading simulation, and optimal layout planning support.
We review single-line diagrams, string layouts, plant capacity, and previous inspection reports to plan full coverage flight paths for both sensors.
Thermal inspections require minimum 500 W/m² irradiance and near-full plant output. We schedule flights between 10 AM – 3 PM under clear-sky conditions.
Automated flight with simultaneous thermal (FLIR/DJI Zenmuse) and RGB camera captures every module from optimal altitude for resolution and coverage.
Thermal and RGB datasets are processed and co-registered. AI-assisted hotspot detection algorithms flag anomalies across the entire dataset automatically.
Each detected anomaly is classified by fault type and severity, geotagged with precise coordinates, and referenced to string/inverter ID for O&M use.
