Definition
IR thermography is the use of thermal infrared cameras to identify temperature anomalies in operating PV modules and electrical connections. Detects hot spots, failed bypass diodes, loose MC4 connectors, and module-level issues.
Key Takeaways
- IR thermography = thermal imaging of operating PV systems.
- Detects hot spots, connector failures, diode burnout.
- Drone-based for utility-scale; handheld for residential.
- Quarterly inspection typical for large plants.
- Complements EL imaging at commissioning.
Frequently Asked Questions
2 commonly searched questions about IR Thermography.
What is IR thermography for solar?
Use of thermal camera (typically drone-mounted) to inspect operating PV plant for thermal anomalies indicating cell defects, hot spots, connector failures.
Drone-based?
Yes, increasingly. Aerial drone with thermal camera covers 5–10 MW per day. Detects sub-module defects from 30–50 m altitude.
Need engineering-backed solar designs?
