Good Essays

ABSTRACT
Photovoltaic (PV) electrical power generation is an important and promising research area because there is high demand for renewable energy systems. To improve the performance of PV array systems so that these energy systems might be better understood and more readily available, more research needs to be done to detect faults on PV array and system monitoring. Through the study of fault detection methods on PV systems, the process of using and analyzing these systems can become more streamlined and reliable. In this paper, most of the fault detection methods that use signal processing and interfere with PV array analysis techniques will be discussed and analyzed. This paper seeks to identify early detection methods that can …show more content…

Additionally, progress in PV research has political benefits because installing PV systems does not require specific resources to be imported from other countries. Because of that advantage, governments across the world have supported the deployment of PV arrays and funded research to improve PV technology [2].
In this paper, an overview of PV is discussed in Section 2. Section 3 presents fault analysis of PV arrays and types of faults, which occur in PV arrays. Fault detection methods of PV arrays are mentioned in Section 4. Finally, Section 5 contains a conclusion about fault detection methods that use signal-processing techniques.
2 OVERVIEW OF PHOTOVOLTAICS
Even though this work presented in this paper analyzes PV arrays at a very sophisticated level, some basic understanding of the electrical attitude and characteristics of individual PV cells is needed to obtain the big picture. This section contains brief explanations of the PV cell. First, Section 2.1 covers single-diode equivalent circuit model of a PV cell and current-voltage characteristic (I-V). Second, the most common models of PV module performance are discussed in Section 2.2. Last, solar cells connections are described in Section 2.3.
2.1 Single-Diode Model and I-V Characteristics
A solar cell is basically a p-n junction made-up in thin layers of semiconductor material. It converts solar energy
