An infrared image starts the investigation
A bright spot on a thermal image can point to a connection problem, shading, a damaged module or simply a temporary condition. Treat it as a sign to investigate, not an automatic replacement order.
Prioritize by consequence
A small anomaly on a low-impact string may be less urgent than a repeat issue near a critical electrical connection. Maintenance priority should follow safety, production impact and the chance of the issue getting worse.
Check the result after the repair
Repeat the inspection after corrective work and compare the result with monitoring data. That confirms whether the intervention solved the real problem instead of only changing what was visible on the first image.
Look for patterns over time
Repeated anomalies in the same area can reveal a design or installation pattern. Combine thermal findings with performance trends and monitoring data for a stronger diagnosis.
Record where an anomaly appears, under what conditions and whether it remains after repair. A hot image alone is not enough.
