Aerial thermal inspection of solar parks and rooftop arrays — finding defective cells, hot spots and underperforming diodes in hours instead of days.
Request a QuoteSolar inspection by drone covers a full utility-scale park in hours — not days. Thermal imaging identifies defective cells, hot spots, bypass diode failures and soiling at panel-level resolution.
High-resolution thermal cameras (DJI Zenmuse H30T or M30T, plus FLIR) detect temperature anomalies down to ±2°C accuracy across thousands of panels per flight.
Inspections follow IEC 62446-3 — the international standard for outdoor thermal inspection of solar panels.
Defects classified by severity: hot spots, bypass diode failures, microcracks, soiling and string-level losses — fed straight to your O&M team.
EASA Specific Category and BVLOS approval — multi-park sweeps possible without per-flight authorisation.
A 10 MW solar park is fully inspected in 2-4 hours. Manual inspection takes 5-10 days.
Radiometric thermal imaging quantifies temperature delta — calibrated to detect cell-level failures.
Each panel is individually georeferenced — defect maps directly back to inverter and string position.
Methodology aligns with international standard for PV thermographic inspection.
Identifying 1-2% of underperforming panels typically pays back inspection cost within months.
Annual or quarterly campaigns track degradation trends — feed performance modelling and warranty claims.
Full thermographic survey of 1-100+ MW solar farms, georeferenced defect maps, prioritised remediation list.
Industrial and commercial PV rooftops — fast thermal flyover identifies hot spots without scaffolding access.
Drone-based inspection of floating photovoltaic installations — ideal for water-based assets where boat access is slow.
Rapid post-event survey to identify physical and electrical damage before insurance claims.
New installation acceptance survey — verify no defects exist before warranty period begins.
Recurring inspection to track degradation, validate string outputs and flag warranty-relevant defects.
A drone with a thermal camera covers a 10 MW solar park in 2-4 hours; manual inspection with a handheld thermal camera takes 5-10 days. Drone inspection is also safer (no roof or ground walking) and produces georeferenced defect maps that link each issue to inverter, string and panel position.
Hot spots (cell-level overheating), bypass diode failures, potential induced degradation (PID), string-level disconnections, microcracks (when combined with EL imaging), soiling patterns, and shading interference. Each defect is classified by severity per IEC 62446-3.
We use radiometric thermal cameras (FLIR / DJI Zenmuse H30T/M30T) with ±2°C absolute accuracy and ≤0.05°C resolution. Combined with controlled flight altitude and meteorological conditions, this is sensitive enough to detect single-cell failures.
Both. You receive a structured defect register (CSV/Excel) with GPS coordinates, severity classification, and panel/string mapping, plus annotated thermal imagery, plus an executive summary with prioritised remediation. Optional: orthomosaic of the entire park overlaid with defects.
Tell us the system size, location and timing. We'll scope the survey, recommend optimal flight conditions, and quote based on per-MW pricing.
