MATLAB-Graphical User Interface to study partial shading of PV array characteristics

摘要

The photovoltaic (PV) arrays can be affected by several factors such as temperature, shading, solar insolation, and the array configuration. In some cases, PV arrays can be completely or partially shaded by obstacles such as clouds and trees or manmade structures. The PV characteristics become complex with the shading effect on the system. Therefore to achieve the maximum power possible, it is important to understand and predict such occurrences. This paper presents a MATLAB Graphical User Interface (GUI) for studying the PV array characteristics under partial shading.
