Effect of Partial Shading on the Performance of Various 4×4 PV Array Configurations

Abstract

Electrical energy usage has drastically increased in recent decades, resulting in significant demand for renewable energy sources, especially solar. With the development of technology, extracting energy from photovoltaic (PV) modules has become easier and more economical. The performance of PV array decreases under an intermittent environment such as partial shading conditions (PSCs), causing fluctuations in PV array power output. This paper presents the analysis of a 4×4 PV array configuration under different PSCs. The power output of PV array depends on factors such as the type of configuration, size of array, and shading patterns. The performance of various types of 4×4 PV array configurations under different shading situations are compared and analyzed in this study, and the results presented.

Traditional and hybrid solar photovoltaic array configurations for partial shading conditions: perspectives and challenges

“…This paper comments the performance of various types of PV arrays, including basic or conventional, hybrid, and advanced configurations. The traditional topologies for PV arrays are SP, BL, HC, and TCT [15]. Under partial shading, TCT is proved as most efficient and ideal method for reducing power loss in PV arrays [16].…”
