An 8MW ground-mount plant in Gujarat was underperforming against its P-90 benchmark, with no obvious fault visible from the inverter-level data. The aggregated readings hid a cluster of localized cell failures that were quietly bleeding DC yield.
The challenge
Cell mismatch and failing bypass diodes had produced hotspots across several strings. Left unchecked, the localized heating would have escalated into irreversible burn damage and a genuine fire-safety risk across the array.
Our approach
A full drone-mounted infrared scan mapped the entire field in a single pass, ranking every anomaly by temperature delta. SolarTrust triaged the worst strings and replaced the failed diodes and modules before the damage could cascade.
Results delivered
- 18% of lost generation restored within two weeks.
- Hotspot severity ranked and remediated across the full field.
- Future failures caught early through scheduled thermography.
