The grid-connected or standalone PV central inverter architecture is comprised of several PV modules which are connected in different ways to form the PV array. The power generation capability of the PV array is primarily affected by partial shading conditions (PSC). Due to PSCs

the power output of the PV array is dramatically reduced

and mismatching losses are induced in the PV modules. Based on the extent of these problems

multiple peaks also appear in the power-voltage (P-V) curve

which makes it very difficult to track the global maximum power point (GMPP). The main objective of this research paper is to model and simulate the series (S)

series-parallel (SP)

bridge-link (BL)

honey-comb (HC)

total-cross-tied (TCT) and proposed triple-tied (TT) solar PV array configurations under various partial shading scenarios. The performance of all PV configurations is evaluated under a uniform approach

considering eight different shading scenarios. The performance of the considered PV configurations is analyzed in terms of their mismatching power losses
