Visual inspection Based on its simplicity, VI is a common inspection method. Although the need of additional equipment. After PV module production, visible also suggested for field inspections [ 25 ]. Defects, which can be detected document for VI reporting to increase comparability. 3.3. Infrared thermography image of a PV module.
The conventional approach to PV module inspection is to use a hand-held infrared sensor and perform visual inspection in-situ by a human operator. The main disadvantages of this method, when applied to a large-scale PV power plant, are that it is time-consuming and costly .
The growth of photovoltaic power plants in both size and number has spurred the development of new approaches in inspection techniques. The most commonly employed methods include visual inspections, current-voltage measurements, infrared thermography, and luminescence imaging.
e essential information which can be used efectively to troubleshoot any problems arising within the system. Sampling for testing of PV modules comprises the procedures involved to select a part of PV modules from the entire solar PV plant for inspection and it should a
The most common inspection techniques employed in PV plants for assessing the performance of PV modules include visual inspection, current-voltage measurements (I-V curves), thermographic imaging, and luminescence imaging, which encompasses both electroluminescence and photoluminescence (Köntges et al., 2014).
Available reports, such as the IEA PVPS Task 13 Review of Failures of Photovoltaic Modules show lists of detectable features of single inspection methods. Often, the described defects are not coherently used in different lists and to find the corresponding signature of another inspection method for the same defects becomes complicated.
