Miscellaneous anomaly
A genuine thermal irregularity that does not match any canonical fault pattern. Recorded as unclassified for field verification rather than forced into the wrong category.
This class is part of the taxonomy our reports are written in, but our analysis does not currently flag it. The page is field reference for your own review. The eight classes we do flag today, and how well, are on the validation page.
Thermal signature
By definition, atypical: a thermal pattern that is clearly abnormal against neighbouring modules but lacks the geometry of the known classes — not cell-shaped, not substring-banded, not at a junction-box or combiner position. Each finding includes the frame and location so it can be assessed on site.
Typical ΔT
Varies by finding; the measured ΔT is reported per detection (typical industry interpretation aligned with IEC TS 62446-3 applies to however the ΔT grades).
What causes it
- Unusual or compound fault presentations spanning multiple categories
- Heating from module-level electronics (optimisers, rapid-shutdown devices)
- Foreign objects on or under the array affecting local temperatures
- Site-specific conditions that legitimate frames capture but standard classes don't describe
Power impact
Unknown until verified — which is the point. Some miscellaneous findings turn out to be benign; others are early presentations of faults that would have been missed if the detector only reported textbook patterns.
Recommended action
Fix: next maintenance window
Verify on site at the next maintenance window: locate the module from the report, inspect it physically and electrically, and reclassify the finding. Persistent unexplained anomalies warrant an I-V test and a note for comparison at the next inspection.
Frequently asked questions
Why report an anomaly the model can't classify?
Because a thermal irregularity is evidence regardless of whether it fits a category. Suppressing unclassified findings would silently discard early or unusual fault presentations; reporting them with a location and ΔT lets a technician make the call.
Are miscellaneous findings usually false alarms?
Some are benign — thermal artefacts of site conditions rather than faults — but the capture-quality gate removes most camera-induced false positives before analysis. What remains is worth a look: it is real heat in an unexpected place.

ΔT figures and abnormality classes on this page describe the typical industry interpretation aligned with IEC TS 62446-3 — indicative engineering guidance, not normative text from the specification. Temperature differentials are only meaningful when captured at ≥600 W/m² irradiance (per the TS) and verified on site before repair work.
