PV Thermography by Drone
Aerial surveys to identify hot‑spots and faulty strings with proper GSD and IR mosaic.
- Fast coverage of utility‑scale PV
- Hot‑spots and string mismatch detection
- IR mosaic and ground validation
Method
- Define GSD and flight plan by layout
- IR/visible acquisition with radiometric payload
- IR mosaic processing and georeferencing
- Ground validation on sample when necessary
- Report with defect classification per module/string
Note: drones are fast carriers for modules; we validate on the ground for doubtful cases.
Deliverables
- PDF report with defect map and severity
- Georeferenced IR/visible mosaic
- Hot‑spot list per module/string
- Recommended corrective actions (cleaning, replacement, I‑V checks)
Reference Standards
- IEC TS 62446-3:2017
- IEC 61724-1:2021
FAQ
What GSD is recommended?
Typically 3–10 cm/pixel for utility‑scale, depending on goals and layout.
Do you need flight authorization?
We operate under applicable regulations and local airspace, with qualified pilots.
What IR payload do you use?
Radiometric cameras with calibration for comparable measurements at scale.
How is ground validation performed?
With close‑range thermography and/or I‑V measurements on sampled modules.
