Utility‑scale solar farms suffer hidden internal PV panel defects such as micro‑cracks, delamination, broken fingers and PID degradation. Visible cameras only capture surface damage, while LWIR thermal modules mainly detect late‑stage hot‑spot overheating.SWIR modules visualize subsurface silicon‑cell luminescence. It reveals early‑stage internal faults invisible to other sensors.

Widely deployed on UAV payloads, fixed monitoring towers and ground inspection robots, SWIR enables daytime EL‑style non‑contact predictive inspection to safeguard power generation yield for large photovoltaic sites.
