220 MW solar farm thermography
VTOL drones with radiometric payloads mapped half a million modules in four days and surfaced 1,412 defective ones.

- 1,412
- defects found
- 4 days
- whole site
- 3.1%
- yield recovered
The challenge
Manual thermal survey of the full array was unschedulable without losing generation.
What we built
RTK-referenced thermal flights, orthomosaic stitching and an anomaly classifier that put module-level defects on the maintenance team's map.
Highlights
- Zero generation downtime during survey
- Defects classed: string, diode, single cell
- Georeferenced to module ID
