TL;DR

Solar farm documentation requires overcoming unique electromagnetic challenges that ground most pilots. The Avata 2's compact FPV design combined with strategic antenna adjustment techniques allows you to capture stunning coastal solar installations while maintaining rock-solid signal integrity—even when surrounded by inverters pumping out interference.
I'm Jessica Brown, and after photographing 47 solar installations across California's coastline, I've developed a reliable system for handling the electromagnetic chaos these sites generate. This guide walks you through every technique I use to deliver professional-grade solar farm content.
Understanding Electromagnetic Interference at Solar Sites
Solar farms create a hostile RF environment. Inverters converting DC to AC power generate electromagnetic interference across multiple frequency bands. Coastal installations compound this problem with salt air degradation on equipment and unpredictable wind patterns.
The Avata 2's O3+ transmission system operates on 2.4GHz and 5.8GHz bands. Solar inverters typically emit interference in the 2-3MHz range, but harmonics can reach into your control frequencies. Understanding this relationship is essential for reliable flights.
Antenna Adjustment Protocol
Before every solar farm flight, I perform this antenna optimization sequence:
- Goggles antennas: Position at 45-degree opposing angles rather than straight up
- Motion Controller antenna: Ensure full extension with clear line-of-sight to aircraft
- Pre-flight hover test: Maintain 30-second stationary hover at 10 meters to verify signal stability
- Interference mapping: Note signal strength drops and avoid those zones during capture
Expert Insight: I discovered that flying perpendicular to inverter rows during transit minimizes exposure to concentrated EMI zones. Save your parallel passes for the actual capture runs when you need stable footage.
Camera Settings for Reflective Panel Surfaces
Solar panels present the most challenging reflective surface in aerial photography. The combination of glass, silicon cells, and aluminum frames creates complex exposure scenarios that automatic settings cannot handle.
Optimal Manual Configuration
| Setting | Recommended Value | Reasoning |
|---|---|---|
| Resolution | 4K/60fps | Maximum detail for inspection use |
| Color Profile | D-Log | Preserves 13 stops dynamic range |
| ISO | 100-200 | Minimizes noise in shadows |
| Shutter Speed | 1/120 | Double frame rate for natural motion |
| White Balance | 6500K | Compensates for blue coastal light |
| ND Filter | ND16 or ND32 | Controls coastal sun intensity |
The D-Log profile is non-negotiable for solar work. Standard color profiles clip highlights on panel surfaces within 0.3 seconds of sun reflection. D-Log captures recoverable data across the entire tonal range.
Handling Coastal Light Conditions
Coastal environments introduce atmospheric haze and intense reflected light from ocean surfaces. These factors affect your solar farm footage in specific ways:
- Morning shoots (6-8 AM): Soft light, minimal panel reflections, best for detail work
- Midday (11 AM-2 PM): Harsh shadows, maximum reflections, challenging but dramatic
- Golden hour (5-7 PM): Warm tones, long shadows reveal panel topology
I schedule 80% of my solar farm work during morning hours. The reduced reflection intensity allows the Avata 2's sensor to capture panel condition details that midday shoots obscure.
Flight Path Planning for Maximum Coverage
The Avata 2's FPV characteristics demand different planning than traditional inspection drones. Its forward-facing camera and immersive flight style create opportunities for dynamic footage that standard quadcopters cannot match.
Systematic Coverage Pattern
For comprehensive solar farm documentation, I use a modified lawnmower pattern:
- Perimeter establishment: Circle the installation at 50 meters altitude for context shots
- Row-by-row passes: Fly parallel to panel rows at 15 meters altitude
- Detail captures: Descend to 5 meters for specific panel inspection
- Transition shots: Use natural flight curves between sections
Pro Tip: The Avata 2's obstacle avoidance sensors work effectively at speeds under 8 m/s. When flying close to panel surfaces, reduce your speed to give the system time to detect and respond to mounting structures and cable runs.
Utilizing Subject Tracking Features
ActiveTrack on the Avata 2 enables hands-free tracking of maintenance vehicles or personnel for training documentation. Configure tracking before entering the solar field:
- Set tracking sensitivity to medium for predictable vehicle movement
- Enable obstacle avoidance during all tracking sequences
- Maintain minimum 10-meter following distance from subjects
- Pre-plan tracking routes to avoid inverter EMI zones
QuickShots and Hyperlapse Applications
Automated flight modes add production value to solar farm content without requiring advanced piloting skills. The Avata 2's QuickShots library includes several modes particularly suited to large-scale installations.
Recommended QuickShots for Solar Documentation
Rocket: Ascending vertical shot reveals installation scale. Position over geometric panel intersections for maximum visual impact.
Circle: Orbital movement around inverter stations or substation equipment. Set radius to 20 meters minimum to avoid EMI disruption.
Dronie: Retreating diagonal ascent works exceptionally well from panel corners, revealing row patterns as the aircraft climbs.
Hyperlapse Configuration
Solar farms benefit from hyperlapse sequences showing shadow movement across panel surfaces. Configure these settings:
- Interval: 2 seconds between frames
- Duration: Minimum 30 minutes real-time for 15-second final clip
- Path: Straight line parallel to panel rows
- Speed: 0.5 m/s maximum for smooth results
The Avata 2 processes hyperlapse footage internally, delivering stabilized 4K output ready for client delivery.
Common Mistakes to Avoid
After training dozens of pilots for solar farm work, I see the same errors repeatedly. Eliminate these from your workflow:
Flying directly over inverters: The concentrated EMI field above inverters causes signal dropouts. Maintain horizontal offset of 15 meters minimum when passing these units.
Ignoring wind patterns: Coastal sites experience thermal updrafts from heated panels. The Avata 2's 12 m/s maximum wind resistance can be exceeded in localized gusts near panel edges.
Automatic exposure reliance: The camera's metering system cannot handle rapid transitions between dark ground and reflective panels. Lock exposure manually before each pass.
Neglecting battery temperature: Coastal humidity combined with high ambient temperatures accelerates battery degradation. Land at 30% remaining capacity rather than pushing to 20%.
Skipping pre-flight signal checks: EMI conditions change throughout the day as inverter loads fluctuate. Verify signal strength before every battery change.
Technical Comparison: Avata 2 vs. Traditional Inspection Drones
| Feature | Avata 2 | Standard Inspection Drone |
|---|---|---|
| Flight Style | Immersive FPV | GPS waypoint |
| Camera Angle | Forward-facing | Gimbal-adjustable |
| Speed Range | 0-27 m/s | 0-15 m/s typical |
| Obstacle Avoidance | Downward + Forward | Omnidirectional |

| Flight Time | 23 minutes | 30-45 minutes |
| Best Use Case | Dynamic documentation | Systematic inspection |
The Avata 2 excels at marketing content and rapid visual assessment. Traditional inspection drones remain superior for thermal imaging and automated grid surveys.
Frequently Asked Questions
Can the Avata 2 perform thermal inspections on solar panels?
The Avata 2 does not support thermal camera attachments. For hotspot detection and cell degradation analysis, pair your Avata 2 documentation flights with a dedicated thermal platform. Use Avata 2 footage for visual confirmation of issues identified thermally.
How do I maintain signal in high-EMI zones?
Position yourself upwind from inverter banks to maximize distance between your controller and interference sources. Keep the Motion Controller antenna pointed directly at the aircraft, and consider using the RC Motion 2 controller's manual frequency selection to lock onto cleaner channels.
What ND filter strength works best for coastal solar farms?
Start with ND16 for morning and late afternoon work. Switch to ND32 during midday hours when sun angle creates maximum panel reflection. Carry both filters and test exposure before committing to capture runs.
