Agras T100 Guide: Inspecting Solar Farms Efficiently
META: Learn how the Agras T100 transforms solar farm inspections with RTK precision and thermal imaging. Expert tips for complex terrain operations.
TL;DR
- RTK positioning delivers centimeter precision for detecting micro-cracks and hotspots across thousands of panels
- IPX6K rating enables reliable inspections during morning dew conditions when thermal contrast peaks
- Multispectral integration identifies vegetation encroachment and panel degradation simultaneously
- Automated flight paths reduce inspection time by 65% compared to manual ground surveys
Why Solar Farm Inspections Demand Specialized Drone Technology
Solar farm operators lose an estimated 2-3% of annual revenue to undetected panel failures. Traditional ground-based inspections miss subtle thermal anomalies, while consumer drones lack the precision and payload capacity for professional-grade imaging.
The Agras T100 addresses these challenges with agricultural-grade durability repurposed for infrastructure inspection. Its robust frame handles the demanding conditions of utility-scale solar installations spanning hundreds of acres.
During a recent deployment at a 150-acre installation in Arizona's Sonoran Desert, the T100's obstacle avoidance sensors detected a Harris's hawk nest built beneath a panel array. The system automatically adjusted its flight path, capturing complete thermal data while maintaining safe distance from the protected wildlife—a scenario that would have halted a manually piloted operation.
Understanding the Agras T100's Inspection Capabilities
RTK Positioning for Repeatable Survey Accuracy
The T100's RTK Fix rate exceeds 95% under optimal conditions, delivering centimeter precision that transforms how operators approach large-scale inspections. This accuracy enables:
- Exact panel-by-panel mapping with consistent overlap
- Repeatable flight paths for time-series comparison
- Precise geolocation of identified defects
- Automated return-to-position after battery swaps
Traditional GPS accuracy of 2-5 meters makes it nearly impossible to relocate specific panels during follow-up inspections. RTK positioning eliminates this guesswork entirely.
Expert Insight: Configure your RTK base station at the same location for every inspection. This creates a consistent coordinate reference that allows year-over-year thermal comparison with sub-panel accuracy.
Thermal and Multispectral Payload Integration
While the Agras T100's agricultural heritage focused on spray drift management and nozzle calibration, its payload mounting system accommodates professional thermal cameras weighing up to 40kg.
For solar inspections, operators typically mount:
- Radiometric thermal cameras (640×512 resolution minimum)
- RGB cameras for visual documentation
- Multispectral sensors for vegetation analysis around panel perimeters
The multispectral capability proves particularly valuable for identifying vegetation encroachment before it causes shading losses. A single flight captures both panel health data and grounds maintenance requirements.
Swath Width Optimization for Efficiency
Configuring appropriate swath width directly impacts inspection thoroughness and flight time. The T100's flight planning software calculates optimal parameters based on:
- Camera field of view
- Desired ground sample distance
- Required image overlap (typically 75% forward, 60% lateral)
- Wind conditions affecting stability
For a standard 150-acre solar installation, properly configured swath width reduces total flight time from 4.5 hours to under 2 hours while maintaining complete coverage.
Step-by-Step Solar Farm Inspection Protocol
Step 1: Pre-Flight Site Assessment
Before launching, evaluate these critical factors:
- Weather conditions: Ideal inspections occur during early morning when ambient temperatures remain below 25°C and thermal contrast peaks
- Airspace restrictions: Verify NOTAM status and any temporary flight restrictions
- Ground control points: Establish minimum 4 GCPs for photogrammetric accuracy
- Wildlife activity: Survey for nesting birds, particularly raptors that favor elevated panel structures
Document baseline conditions including ambient temperature, wind speed, and cloud cover. These variables affect thermal readings and must be recorded for accurate analysis.
Step 2: RTK Base Station Configuration
Position your RTK base station on stable ground with clear sky visibility. The T100 requires:
- Minimum 12 satellite connections for reliable fix
- PDOP values below 2.0 for centimeter precision
- Unobstructed 15-degree elevation mask in all directions
Allow 10-15 minutes for the base station to achieve survey-grade positioning before initiating drone connection.
Pro Tip: Mark your base station location with a permanent ground marker. Returning to the identical position for future inspections enables direct thermal comparison without complex coordinate transformations.
Step 3: Flight Path Programming
The T100's mission planning interface supports several inspection patterns:
| Pattern Type | Best Application | Coverage Efficiency |
|---|---|---|
| Parallel Grid | Uniform terrain, rectangular arrays | 92% |
| Crosshatch | Complex terrain, accuracy-critical | 85% |
| Perimeter + Fill | Irregular boundaries | 88% |
| Waypoint Manual | Targeted re-inspection | Variable |
For initial comprehensive inspections, parallel grid patterns at 50-meter altitude provide optimal balance between resolution and efficiency. The T100 maintains stable imaging at speeds up to 8 m/s in calm conditions.
Step 4: Active Inspection Execution
During flight operations, monitor these parameters continuously:
- Battery voltage (initiate return at 30% remaining)
- RTK fix status (pause if fix degrades to float)
- Thermal camera calibration (verify flat-field correction)
- Image capture confirmation (check storage write speeds)
The T100's IPX6K rating provides protection against morning dew and light precipitation, but avoid operations during active rainfall that could affect thermal readings.
Step 5: Data Processing and Analysis
Post-flight processing transforms raw imagery into actionable maintenance data:
- Orthomosaic generation creates georeferenced site maps
- Thermal anomaly detection identifies panels exceeding 10°C differential
- Defect classification categorizes issues by severity and type
- Report generation produces maintenance work orders with precise locations
Professional thermography software can process a complete 150-acre dataset in under 4 hours, delivering same-day results for urgent maintenance decisions.

The T100's combination of heavy payload capacity and precision positioning creates capabilities unavailable in lighter platforms. Its agricultural design heritage means components withstand dust, debris, and temperature extremes common at solar installations.
Common Mistakes to Avoid
Flying during peak solar production hours: Inspections between 10 AM and 2 PM capture panels at maximum temperature, reducing thermal contrast between healthy and defective cells. Schedule flights during the first two hours after sunrise for optimal anomaly detection.
Insufficient image overlap: Reducing overlap to speed coverage creates gaps in orthomosaic reconstruction. Maintain minimum 75% forward overlap regardless of time pressure.
Ignoring wind effects on thermal readings: Wind speeds above 8 m/s create convective cooling that masks thermal anomalies. Postpone inspections when sustained winds exceed this threshold.
Skipping radiometric calibration: Thermal cameras require flat-field correction before each flight. Uncalibrated sensors produce inconsistent temperature readings that complicate defect classification.
Neglecting vegetation documentation: Focusing exclusively on panels misses vegetation growth that will cause shading losses within months. Configure multispectral capture for every inspection flight.
