Team Vibhawa recently conducted a drone-assisted infrared thermography inspection for a 1MW rooftop solar PV system at a leading industrial facility, adhering to IEC TS 62446-3 standards.
Using the DJI Matrice 350 RTK equipped with an H20T thermal payload, the aerial survey was carried out in collaboration with licensed drone pilots, guided by our in-house Level 2 and Level 3 Certified Thermographers. The inspection was performed at a 3 cm/px Ground Sample Distance (GSD), enabling sub-module level precision and high-resolution thermal imaging.
As the only company in Sri Lanka with an in-house Level 3 Certified Thermographer, Vibhawa’s team led the thermal image analysis using DJI’s proprietary software to detect critical anomalies such as cracked modules, delamination, hot spots, and other faults.
This comprehensive, standards-compliant inspection not only aids in warranty validations and preventive maintenance but also enhances system performance and long-term reliability.
By combining advanced drone technology with deep thermal imaging expertise, Vibhawa empowers solar asset owners to reduce downtime, improve ROI, and protect their energy investments.
