Solar farm inspections across rugged terrain present unique challenges that standard drones simply cannot handle. The DJI Avata 2's compact FPV design, combined with intelligent tracking features, transforms how photographers and inspectors document sprawling photovoltaic installations—this guide shows you exactly how to execute professional solar farm tracking missions.
Why the Avata 2 Excels at Solar Farm Documentation
Traditional inspection drones struggle with the repetitive geometry of solar arrays. Rows upon rows of identical panels create visual confusion for both pilots and automated systems.
The Avata 2 changes this equation entirely.
Its 1/1.3-inch CMOS sensor captures 4K/60fps footage with enough detail to identify micro-cracks, hotspots, and connection failures. The 155° super-wide FOV means fewer passes to cover each array section.
But the real advantage? Maneuverability.
Weighing just 377 grams, the Avata 2 navigates between panel rows, under mounting structures, and around inverter stations where larger drones cannot operate safely.
Essential Antenna Positioning for Maximum Range
Here's what separates amateur solar farm flights from professional operations: antenna discipline.
Expert Insight: Your Goggles 3 antennas aren't omnidirectional. Position them at 45-degree outward angles from vertical—this creates an overlapping signal pattern that maintains connection as your Avata 2 weaves through metal-heavy solar infrastructure.
Optimal Positioning Protocol
Follow this sequence before every solar farm mission:
- Step 1: Face the center of your planned flight area
- Step 2: Tilt left antenna 45 degrees left, right antenna 45 degrees right
- Step 3: Ensure antennas point slightly upward, never downward
- Step 4: Maintain line-of-sight to your takeoff position throughout the flight
- Step 5: Position yourself elevated if possible—truck beds and equipment trailers work excellently
Metal solar panel frames and inverter housings create signal reflection zones. Your 45-degree spread compensates for these multipath interference patterns.
Configuring ActiveTrack for Panel Row Inspection
The Avata 2's subject tracking capabilities adapt remarkably well to infrastructure inspection—with proper configuration.
Initial Setup
Access the DJI Fly app's tracking menu and adjust these parameters:
- Set Tracking Sensitivity to Medium-Low (prevents erratic corrections near reflective surfaces)
- Enable Obstacle Avoidance in Bypass Mode rather than Brake Mode
- Configure Maximum Tracking Speed to 8 m/s for smooth, cinematic documentation
- Activate Subject Lock to maintain focus on specific panel sections
Execution Technique
Rather than tracking a moving subject, use ActiveTrack creatively:
Lock onto a fixed reference point—an inverter station, transformer, or distinctive panel section. The Avata 2 maintains orientation toward this point while you fly perpendicular passes across the array.
This technique produces perfectly aligned inspection footage without the cognitive load of manual camera control.
Pro Tip: Place a high-visibility marker (orange cone or flag) at each array corner before flying. These become reliable tracking targets that the Avata 2's recognition system locks onto instantly.
D-Log Configuration for Defect Detection
Standard color profiles crush the subtle luminance variations that indicate panel problems. D-Log preserves this critical data.
Camera Settings for Inspection Work
| Parameter | Recommended Setting | Rationale |
|---|---|---|
| Color Profile | D-Log M | Maximum dynamic range for post-processing |
| ISO | 100-400 | Minimizes noise in shadow detail |
| Shutter Speed | 1/120 minimum | Eliminates motion blur on panel surfaces |
| White Balance | 5600K (locked) | Consistent color across entire inspection |
| Resolution | 4K/30fps | Balance of detail and file management |
| Bitrate | High | Preserves gradient information |
Post-Processing Workflow
D-Log footage appears flat and desaturated—this is intentional.
Apply a Rec.709 LUT as your starting point, then increase contrast and clarity to emphasize surface irregularities. Panel defects typically appear as:
- Darker patches: Cell degradation or internal shorts
- Bright spots: Reflection anomalies indicating physical damage
- Color shifts: Potential thermal issues requiring IR follow-up
QuickShots and Hyperlapse for Documentation
Beyond inspection, solar farm operators increasingly require marketing and stakeholder documentation. The Avata 2 delivers both in single flights.
Effective QuickShots Patterns
Rocket: Ascending vertical shot from array center—establishes scale dramatically
Circle: Orbit around inverter stations—highlights infrastructure integration
Dronie: Retreating climb from ground level—reveals terrain context
Hyperlapse Strategy
Solar farms photograph beautifully during golden hour when low-angle light creates shadows defining each panel row.
Configure Hyperlapse with:
- Interval: 2 seconds
- Duration: 15-20 minutes real-time
- Path: Linear flight along primary access road
- Altitude: 25-30 meters for optimal perspective
The resulting footage compresses a complete site overview into 30-45 seconds of compelling visual content.
Flight Pattern Strategies for Complex Terrain
Solar installations on hillsides, former mining sites, and agricultural land present elevation challenges.
Terrain-Following Technique
The Avata 2 lacks automated terrain following, but manual technique compensates:
- Pre-flight: Study topographic maps or satellite imagery
- Altitude reference: Set altitude relative to highest terrain point, not takeoff location
- Visual cues: Watch shadow length beneath the drone—consistent shadows indicate consistent ground clearance
- Speed management: Reduce velocity on uphill approaches, increase on downhill runs
Wind Considerations
Solar farms often occupy exposed locations with significant wind.
The Avata 2 handles 10.7 m/s sustained winds, but panel-induced turbulence adds complexity. Fly upwind first while batteries are fresh, return with wind assistance.
Technical Comparison: Avata 2 vs. Traditional Inspection Drones
| Feature | Avata 2 | Standard Inspection Drone |
|---|---|---|
| Weight | 377g | 800-1200g typical |
| FOV | 155° | 84° typical |
| Maneuverability | Exceptional | Moderate |
| Flight Time | 23 minutes | 30-40 minutes |
| Close-Proximity Work | Excellent | Limited |
| Pilot Skill Required | Moderate-High | Low-Moderate |
| FPV Immersion | Full | Screen-based |
| Obstacle Sensing | Downward | Multi-directional |
| Cost | Lower | Higher |
The Avata 2 trades extended flight time for unmatched agility in confined spaces—a worthwhile exchange for detailed infrastructure documentation.
Common Mistakes to Avoid
Flying during peak sun hours: Midday sun creates harsh reflections that blind the camera sensor and obscure panel defects. Schedule flights for 2 hours after sunrise or 2 hours before sunset.
Ignoring magnetic interference: Solar farm inverters generate electromagnetic fields. Calibrate your compass at least 50 meters from any electrical equipment.
Overlooking battery temperature: Cold morning inspections reduce battery performance by 15-20%. Warm batteries to 20°C minimum before flight.
Neglecting ND filters: Reflective panel surfaces require ND8 or ND16 filters to maintain proper exposure without excessive shutter speed.
Single-pass coverage: Professional documentation requires minimum 70% overlap between passes for complete coverage verification.
Frequently Asked Questions
Can the Avata 2 detect thermal anomalies in solar panels?
The Avata 2's standard camera captures visible light only—it cannot directly detect thermal signatures. However, D-Log footage often reveals color and luminance variations that correlate with thermal issues. For definitive thermal analysis, pair Avata 2 visual documentation with dedicated thermal drone passes.
What flight altitude works best for solar panel inspection?
Optimal altitude depends on your documentation goal. For defect identification, fly at 8-12 meters to capture individual cell detail. For array overview and marketing content, 25-35 meters provides context while maintaining panel visibility. Always maintain minimum 5-meter clearance from any structure.
How many batteries should I bring for a complete solar farm inspection?
Calculate based on array size: the Avata 2 covers approximately 2-3 hectares per battery at inspection speeds. A 10-hectare installation requires 4-5 batteries minimum, plus one reserve. Bring a portable charging solution for extended sessions.
Solar farm documentation demands precision, adaptability, and technical knowledge that the Avata 2 delivers when properly configured. Master these techniques, and you'll produce inspection footage that satisfies both engineering requirements and marketing objectives.
