Our Sun Pvt Ltd (OPL) 50MWp PV Solar Power Plant
A comprehensive drone-guided thermal audit to ensure the structural and operational integrity of a utility-scale solar farm.
The Challenge
Inspecting a 50MWp utility-scale plant manually is nearly impossible with solar assets leaking millions of rupees every year. The client faced potential very high revenue loss due to unidentified string failures, bypass diode issues, and vegetation shading across a massive geographic footprint that would take weeks to cover on foot.
Measurable Impact
90% Faster Inspection Speed
Captured high-fidelity thermal and RGB data for the entire 50MWp site in a fraction of the time required for manual PV scanning.
100% Granular Visibility
Identified specific anomalies ranging from individual cell hotspots and multi-cell failures to entire string outages affecting hundreds of panels.
Precise Defect Localization
Pinpointed exact coordinates of heated modules and inoperative inverters, allowing for immediate, targeted maintenance rather than broad troubleshooting.
The Solution & Outcome
Global Air Drones (via Buraq Geo Services) integrated Matrice 350 RTK and Mavic 3T Enterprise thermal drones to sweep and capture the data needed for a +16 Million Rs. warranty claim.
By providing thermal data, we enabled the client to detect critical thermal signatures (hotspots) that indicate internal panel degradation. This allowed Our Sun Pvt Ltd to validate warranty claims, prevent fire hazards, and restore peak power generation efficiency across the plant.
Key Technologies Used
- DJI Matrice 350 RTK for precision positioning and large-scale coverage
- DJI Mavic 3T Enterprise with thermal imaging capabilities
- High-resolution RGB and thermal data capture
- GPS-tagged anomaly mapping for precise defect localization
