Drone Thermal Inspection & Aerial Thermography
Professional aerial thermography for solar farms, commercial roofs, electrical systems, wind turbines, and agricultural operations. Calibrated radiometric data — not colorized snapshots.
What Is Aerial Thermography?
Aerial thermography — also called drone thermal inspection or aerial thermal imaging — is the practice of capturing calibrated infrared data from an unmanned aircraft to detect temperature anomalies invisible to the naked eye. Every surface emits thermal radiation proportional to its temperature. A radiometric thermal sensor measures this radiation and converts it into precise temperature values at each pixel.
The result is a georeferenced thermal map of your asset — whether that's a 500 MW solar farm, a 200,000 sq ft warehouse roof, or a high-voltage substation. Anomalies like moisture intrusion, failing bypass diodes, loose electrical connections, or insulation gaps appear as distinct thermal signatures that trained analysts classify by severity.
At Aerial Accuracy, we fly strict automated grid patterns with 640x512 radiometric sensors and 2cm RTK GPS positioning. This isn't consumer-grade thermal photography — it's quantitative, repeatable, and defensible data capture that meets the requirements of IEC 62446-3, ASTM C1153, and NFPA 70B.

| Factor | Drone Thermal Inspection | Handheld Thermography |
|---|---|---|
| Coverage | 100% of surface area, overhead nadir angle | Limited to line-of-sight, oblique angles |
| Speed | 50+ acres/hour for solar; full rooftop in minutes | Hours per building, days for large arrays |
| Safety | No roof access, scaffolding, or bucket trucks | Requires physical access to dangerous locations |
| Positioning | 2cm RTK GPS — every anomaly is georeferenced | Manual notation of approximate locations |
| Repeatability | Automated flight paths, identical parameters each survey | Varies by operator, angle, and distance |
| Deliverable | Stitched radiometric orthomosaic with GPS coordinates | Individual images with manual annotation |
How Our Aerial Thermography Process Works
Scope & Plan
We review your asset, check airspace (LAANC authorization), define flight parameters, and schedule around optimal thermal conditions — typically early morning or after sunset for roofs, solar noon for PV arrays.
Fly & Capture
Automated grid flights at consistent altitude with 70-80% overlap. The 640x512 radiometric sensor captures calibrated temperature data at every pixel while RTK GPS tags each frame with 2cm positioning.
Analyze & Report
Thermal data is processed into georeferenced orthomosaics. Anomalies are classified by severity per applicable standards (IEC 62446-3 / ASTM C1153 / NFPA 70B) and delivered as annotated PDF reports with GPS coordinates.
Service Area
Based in Hale Center, TX — zero travel fees within 40 miles covering Hale, Floyd, Swisher, Castro, Lamb counties and Lubbock metro. Extended coverage across the ERCOT footprint with transparent travel pricing and advance scheduling.
Founder-led. Not a national franchise, online marketplace, or outsourced contractor network.
Drone Thermal Inspection FAQ
What is a drone thermal inspection?
A drone thermal inspection uses an unmanned aircraft equipped with a radiometric infrared camera to capture calibrated temperature data across structures, equipment, or terrain. Unlike handheld thermal cameras limited to line-of-sight, aerial thermography covers large areas quickly and safely — entire rooftops, solar arrays, or transmission corridors in a single flight. The radiometric data allows precise temperature measurement at every pixel, not just visual heat patterns.
What industries use aerial thermography?
Aerial thermography is used across energy (solar PV, wind turbines, substations, BESS), building envelope (commercial roofs, cold storage, warehouses), agriculture (irrigation leak detection, crop stress, feedlot monitoring), and infrastructure (cell towers, grain elevators, pipelines). Any application where temperature anomalies indicate equipment failure, moisture intrusion, or energy loss benefits from drone thermal inspection.
How is drone thermal inspection different from handheld thermography?
Handheld thermal cameras require roof access, scaffolding, or bucket trucks and can only image what the operator can physically reach. Drone thermal inspection captures overhead, nadir-angle imagery of entire structures in minutes with consistent altitude, overlap, and angle — producing georeferenced thermal maps rather than isolated snapshots. For solar farms, this means 100% module coverage rather than spot-checking. For roofs, it means full-surface moisture mapping rather than sampling.
What equipment do you use for aerial thermography?
We fly an Autel EVO II Dual 640T RTK V3 with a 640x512 uncooled VOx radiometric thermal sensor and a 50MP RGB camera. The RTK GPS provides 2cm positioning accuracy for georeferenced deliverables. This is a professional-grade radiometric system — every pixel records a calibrated temperature value, not just a colorized heat image.
How much does a drone thermal inspection cost?
Pricing depends on the scope: small commercial roofs start around $600, utility-scale solar inspections are quoted per-MW, and electrical thermography is typically quoted per-facility. We offer zero travel fees within 40 miles of Hale Center, TX. Contact us for a custom quote based on your specific asset and deliverable requirements.
What standards do your inspections follow?
Our methodologies are informed by IEC 62446-3 for solar PV thermography, ASTM C1153 for roof moisture surveys, and NFPA 70B for electrical thermography. We follow these frameworks for flight parameters, environmental conditions, data capture, and anomaly classification to ensure defensible, standards-aligned deliverables.
