Thermal Camera Specifications
Solar farm operators, insurance adjusters, and facility engineers need specific technical capabilities that separate professional thermal inspection from recreational drone cameras. Our equipment supports field methods aligned with IEC TS 62446-3 (solar), ASTM C1153 (roofs), and NFPA 70B (electrical). These methods follow the applicable frameworks; they are not certification or accreditation by those bodies.

Why 640×512 Resolution Matters for Solar Inspections
The aircraft records 640×512 radiometric thermal frames. Thermal ground resolution depends on flight altitude, lens geometry, and field conditions, so signatures are screened as investigation targets rather than per-module diagnoses.
Higher sensor resolution preserves more thermal detail at the same altitude. Whether imagery meets the applicable use case and IEC requirements depends on the complete capture geometry and quality review; flagged signatures still require ground verification before maintenance decisions.
RTK GPS Positioning System
Identifying thermal anomalies is only valuable if maintenance crews can locate them. In million-module solar farms or 100,000+ square foot commercial roofs, "row 47, somewhere in the middle" doesn't enable efficient repairs. Our RTK (Real-Time Kinematic) positioning system supplies a manufacturer camera-position specification. Deliverables can include georeferenced visual and radiometric thermal layers for use in the client's GIS; we do not issue per-module diagnoses.
Manufacturer Camera-Position Specifications (RTK Fix)
- Horizontal camera position: 2cm + 1ppm (RTK Fix mode)
- Vertical camera position: 3cm + 1ppm (RTK Fix mode)
- RTK Network: Texas VRS network, NTRIP protocol
- Fallback Mode: Standard GPS (3-5m accuracy) when RTK unavailable
- Update Rate: 10Hz position updates
Practical Impact
- Solar Arrays: Review georeferenced visual and thermal layers in the client's GIS and prioritize ground checks
- Commercial Roofs: Map affected zones for targeted core sampling; thermal screening does not identify the exact entry point
- Electrical Substations: Associate screening findings with documented equipment identifiers for qualified review
- Wind Turbines: Document blade section and clock position for qualified follow-up teams
Georeferenced Deliverables
Georeferenced visual and radiometric thermal layers are delivered in GIS-compatible formats. Thermal signatures remain investigation targets, not root-cause diagnoses. These layers provide georeferenced context rather than survey coordinates, and we do not issue per-module diagnoses.

What This Means for Solar Farm Operators
This certification demonstrates formal training in thermal physics, emissivity considerations, reflected temperature compensation, and atmospheric transmission—factors that affect accurate temperature measurement in outdoor solar inspections. Combined with IEC TS 62446-3 protocol knowledge, this training supports traceable field documentation for manufacturer or insurance evaluation. Acceptance depends on the reviewer and claim.
Equipment Comparison: Professional vs. Basic Thermal Drones
| Feature | Our Equipment (Professional) | Basic Thermal Drones |
|---|---|---|
| Thermal Resolution | 640×512 (327,680 points) | 160×120 or 320×256 (19,200-81,920 points) |
| Temperature Accuracy | Manufacturer-specified ±3°C or ±3% under stated operating conditions | ±5°C typical (uncalibrated) |
| Radiometric Data | Full 14-bit apparent-temperature data in every pixel | Visual thermal overlay only (no temp data) |
| GPS Positioning | Manufacturer camera-position specification (RTK Fix) | 3-5m standard GPS |
| Thermal Capture Detail | 640×512 radiometric thermal frames | Fewer sensor pixels at the same altitude |
| Warranty Documentation | Reports aligned with the IEC TS 62446-3 framework | Visual snapshots (often rejected) |
| Operator Training | Level I sUAS Applications Certified Thermographer + Part 107 | Part 107 only (no thermography training) |
Cost of Inadequate Equipment
A 600MW solar farm with 1.36 million modules may have 500-2,000 defective panels at any given time. Lower-resolution thermal cameras preserve less detail at the same altitude. Thermal resolution depends on flight altitude, and flagged signatures remain investigation targets for ground verification.
