PA-YOLO-Based Multifault Defect Detection Algorithm for PV Panels

Table 1

Comparison of different network models.

Algorithm	mAP		Fracture	Hot spot	Plant	PV panel string	FPS
Lite^ourg-YOLOv5	83.1	77.1	86.8	68.4	80.7	96.6	65
YOLOv5-s	83.4	77.3	96.1	60.7	83.7	93	62
YOLOX-m	85	79.5	75	80	93	92	78
YOLOv7	87.7	79.9	98.7	70.3	89.9	91.9	80
PA-YOLO	94.5	91.8	99.4	88.6	92.7	97.3	83

Note: data in the table are expressed as percentages except FPS. The unit of FPS is frames per second. “Battery string” and “PV panel string” in Table 1 represent the same meaning.
