To further improve both the detection accuracy and speed for detecting photovoltaic module defects, a detection method of photovoltaic module defects in EL images with faster detection speed and higher accuracy is proposed based on VarifocalNet.

What are defects in a PV module?

This technique is typically used to identify defects in a PV module, such as structural defects that may arise from imperfect semiconductor processes, unmatched crystalline lattices, or faulty electrical connections [ 44 ].

How to improve the detection speed of photovoltaic module defects?

Improving detection speed is the focus of the one-stage method, while the two-stage method emphasizes detection accuracy. In the practical detection of photovoltaic module defects, we should consider not only the detection speed but also the detection accuracy. The VarifocalNet is an anchor-free detection method and has higher detection accuracy 5.

Can solar photovoltaic panel surface defect detection be applied to industrial inspection?

When solar photovoltaic panel surface defect detection is applied to industrial inspection, the primary focus lies in achieving a highly accurate and precise model with exceptional localization capabilities, and the training model will basically not affect the detection speed.

How to diagnose a failure of a PV module?

Basic techniques for failure diagnosis PV module undergoes several standard quality tests before it is supplied to customers. Those tests' primary objective is to determine the possible factors that cause a breakdown of the solar panel, which is the heart of a PV system.
