Thermography for Solar Panel Inspection Using Drones comes into play. By combining thermal imaging with aerial drone technology, solar field operators can quickly detect issues, prevent power loss, and boost efficiency—all without setting foot on a rooftop or solar array.
As India moves toward a greener energy future, solar power plays a critical role. But maintaining large solar farms efficiently is a challenge—especially when it comes to identifying faulty panels or underperforming modules.
What is Thermography in Solar Panel Inspection?
Thermography involves capturing infrared images that show surface temperature variations. When applied to solar panels, it helps detect:
- Hotspots (damaged cells or modules)
- Diode failures
- Interconnection faults
- Soiling or shading issues
- Degraded panels
These issues may not be visible to the naked eye but drastically affect performance and safety.
Why Thermography Matters in Solar Panel Inspection?
Thermal imaging, also known as infrared thermography, detects heat patterns emitted by objects. When applied to solar panels, it helps identify:
- 🔥 Hotspots caused by damaged cells
- 🔌 Faulty connections or bypass diodes
- 🌫️ Dirt buildup causing thermal imbalances
- ⚡ Inverter and junction box overheating
Why Use Drones for Thermographic Solar Panel Inspection?
