ABSTRACT Generally PV generators are considered reliable compared to other systems, but like all processes, a PV system can be exposed to several failures causing the PV system to malfunction. Several studies have found that the reliability of PV systems is highly dependent on the equipment used for the construction of PV panels, temperature, humidity and solar radiation. A PV system can have several defects, be it defects of construction types, or material and electrical defects caused by climatic conditions. As such, we can cite the fault most commonly encountered in a PV generator which is the partial shading defect. This paper is organized as follows. Section II will generally introduce PV systems and their characteristics. Section III will introduce bond-graph models for PV systems. Section IV will discuss the problem of optimal sensor placement. Sections V and VI will validate the method through simulations and experiments. Finally, section VII will discuss the results.
