Can imaging technology be used to analyze faults in photovoltaic (PV) modules?
The massive growth of PV farms, both in number and size, has motivated new approaches in inspection system design and monitoring. This paper presents a review of imaging technologies and methods for analysis and characterization of faults in photovoltaic (PV) modules.
How to determine the quality of photovoltaic modules?
The life cycle of the PV modules, which is associated with the quality of photovoltaic modules, greatly affects the return of investment and total power production. Determination of quality and reliable photovoltaic modules is achieved by testing, product certification, and inspection services.
What is PV module life cycle inspection?
PV module life cycle inspection services can be satisfied using product-specific tests and certification, whereas long-term failures can be compensated with continuously decreasing module costs due to technological and manufacturing advancements.
Do PV modules need certification?
Accredited certification of PV modules requires specific schemes for production, testing, and inspection of photovoltaic modules. In this study, the importance of testing, certification, and inspection processes for PV modules is emphasized by critical case studies.
What are the disadvantages of PV module inspection?
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 .
When should a PV module be tested?
The presentation of these test results is suggested during planned factory inspections. In the PV production line, an electroluminescence (EL) tester or laser tester is a type of checkpoint in which defective modules are determined and classified. Each PV module is recommended to be tested in these devices after or before lamination.
