AI Customer ServiceThis paper presents a benchmark dataset and results for automatic detection and classification using deep learning models trained on 24 defects and features in EL images of crystalline silicon solar cells. The dataset consists of 593 cell images with ground truth masks corresponding to the pixel-level labels for each feature and defect.
The models tested are effective in detecting, localizing, and quantifying multiple features and defects in EL images of solar cells. These models can thus be used to not only detect the presence of defects, but to track their evolution over time as modules are re-imaged throughout their lifetime.
Automatic defect detection and classification in solar cells is the subject of many publications since EL imaging of silicon solar cells was first introduced by Fuyuki et al. for detection of deteriorated areas in solar cells in 2005.
We published an automatic computer vision pipeline of identifying solar cell defects. Tools can handle field images with a complex background (e.g., vegetation). Tools can be applied to other kinds of defects with transfer learning. We compared the performance of classification and object detection neural networks.
Generally, solar cell defects can be divided into two broad defect categories: intrinsic and extrinsic defects. Figure 1 shows an example of a cell extracted from an EL image of a photovoltaic module. Fig. 1. The electroluminescence test applied to a photovoltaic panel cell. Note as the cell presents a dark area in the bottom-right part
Failures & Defects in PV Systems: Typical Methods for Detecting Defects and Failures Generally,any effect on the PV module or device which decreases the performance of the plant, or even influences the module characteristics, is considered a failure. A defect is an unexpected or unusual happening which was not observed on the PV plant before.
