Evaluation of Surface Crack Formation in Photovoltaic
Stefan Mitterhofer, Michael Kempe, Xiaohong Gu Abstract—Backsheet cracking is among the most commonly observed degradation modes of photovoltaic (PV) modules in the field.
The presence of cracks in PV panels can have a substantial effect on their overall performance and efficiency. Cracks in the panel cause a decline in the electricity output of the solar PV system, resulting in diminished overall efficiency.
Advancing renewable energy solutions requires efficient and durable solar Photovoltaic (PV) modules. A novel mechanism based on Deep Learning (DL) and Residual Network (ResNet) for accurate cracking detection using Electroluminescence (EL) images of PV panels is proposed in this paper.
The detection of cracks in PV panels is a difficult task, as PV panels are brittle and need careful inspection. Although these cracks are often detected using methods such as Electroluminescence (EL) imaging, advanced image processing techniques are needed for proper classification and quantification of the defects identified.
Cracks in the panel cause a decline in the electricity output of the solar PV system, resulting in diminished overall efficiency. Cracks in Building-Integrated Photovoltaic (BIPV) modules can lead to a significant decrease of up to 43% in power output 7.
