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

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