Solar Photovoltaic Inspection

Thermal infrared imaging combined with AI-powered analysis identifies hotspots, bypass diode faults, and mechanical damage across entire PV arrays in a fraction of the time manual inspection requires.

Solar thermal anomaly detection — modules with thermal overlays and bounding boxes highlighting hotspots and anomalies

Electrical Anomalies

Module and cell hotspots from thermal imaging
String mismatch identification

Mechanical & Optical

Cracked glass and micro-crack detection
Delamination and backsheet damage
Snail trails and discoloration patterns

AI-Enhanced Detection: Modern deep learning models like HOTSPOT-YOLO achieve over 90% mean average precision for detecting small thermal anomalies in PV arrays, while maintaining real-time performance during flight. Combined with SegFormer-based segmentation for snail trail and hotspot identification, our processing pipeline delivers comprehensive defect reports that integrate directly into maintenance workflows.

Building & Facade Inspection

Detect exterior defects, thermal bridging, moisture intrusion, and insulation failures on building facades and rooftops — visible and infrared, side by side, with AI-enhanced defect callouts.

Why Drones Replace Rope Access

Scaffolding setup: 2–5 days, $10k–$50k+
Drone survey: same-day, fraction of the cost
Rope access: weather-limited, high liability
Drone: broader weather window, no fall risk
Manual photos: inconsistent angles, no geo-reference
Drone: geotagged, repeatable flight paths
Thermal walk-around: partial coverage, ground-level only
Drone thermal: full facade, every floor, every side

What We Detect

Cracks, spalling, and surface deterioration
Thermal bridging and insulation gaps
Moisture intrusion and water damage patterns
Window seal failures (visible on thermal)
EIFS/cladding delamination
Roof membrane defects and ponding areas
Efflorescence and masonry deterioration
Balcony and parapet structural concerns

Consistency at Scale: AI applies identical analysis logic to every image — eliminating inspector bias and inconsistent severity ratings. Findings integrate directly into maintenance workflows, enabling engineers to track deterioration progression across inspection cycles and support budget decisions with reliable, repeatable data.

Frequently Asked Questions

How accurate are drone inspection measurements?

Using RTK ground control points, we achieve horizontal accuracy of ±2–3 cm and vertical accuracy of ±3–5 cm. This meets ASPRS positional accuracy standards and is sufficient for engineering-grade assessments, structural monitoring, and compliance reporting.

Can drone thermal imaging detect problems inside walls or under surfaces?

Thermal cameras detect surface temperature differentials caused by subsurface issues — such as moisture behind cladding, insulation voids, or delamination in concrete. While they do not image through materials directly, the thermal contrast reveals hidden problems that are invisible to the naked eye.

How does AI improve inspection accuracy compared to manual review?

AI applies consistent detection logic across every image, eliminating inspector fatigue and subjective severity ratings. Modern models achieve over 90% recall for thermal anomalies in PV arrays and can automatically classify crack widths, corrosion extent, and spalling severity — producing reports in hours instead of days.

What size of solar farm can you inspect in one day?

With a Matrice 4T running automated waypoint missions, a single crew can inspect 200–500+ acres of PV panels per day depending on site layout and flight conditions. Each defect is automatically geotagged and classified for immediate maintenance prioritization.

Can drones actually spread de-icing agents on rooftops?

Yes. Spray drones like the DJI Agras T50 with a 40L tank can spread liquid or granular de-icing agents across commercial rooftops. This eliminates the need for crews to work on icy, elevated surfaces — reducing both risk and labor costs while providing more uniform coverage than manual application.

What regulations apply to inspection drone operations in Canada?

Commercial drone inspections in Canada require compliance with Transport Canada's Canadian Aviation Regulations (CARs Part IX). Depending on site and airspace, operations may fall under Basic, Advanced, or SORA/SAIL-based approvals. SkyFlow ensures all operations meet current regulatory requirements including the 2025 Standard 922 framework.

Do you provide the raw data or just reports?

Both. Every project includes engineer-ready reports with annotated defects, severity ratings, and priority matrices. You also receive all raw imagery, thermal data, and 3D models for your own analysis or integration into existing asset management systems.
