Physical relocation of PV panel for optimization of power under PSC in PV array

This paper implements a solar photovoltaic (PV) array based on Global Maximum Power Point (GMPP), Power loss and Fill Factor. It shows the effect of Partial Shading Condition (PSC) on a PV array which certainly diminishes the output power. A reconfiguration scheme has been tested with a 4×4 PV array in which the array is relocated to deliver optimized power. Some of the existing configurations such as Total Cross Tied (TCT), Honey Comb (HC), Bridge Link (BL) and Series-Parallel (SP) are compared with Rearrange Square (RS) method based on three performance indices. MATLAB/Simulink modeling of all configurations has been done to achieve PV characteristics and analyze their bar graphs. This work delve into performance based on different shading patterns like short wide, long wide, short and narrow. The novelty of this paper is to present that physical relocation can be the best choice for array reconfiguration in terms of cost to disperse the shade in PV array.
