Abstract

This research demonstrates a comparative study of the performance of a rated 10 W, 5´X5 PV Array based on PV array topology; SP, BL, HC, and TCT partial shade patterns; SW, SN, LW, LN, and NS conventional PV array configuration IC and reconfiguration using the Magic Square row-shifting technique MS1-MS5 by simulation on MATLAB/Simulink. The result of 30 case studies found that; (1) TCT topology had the highest GMPP value compared to other topology in 21 cases, representing 70 %. (2) Eight cases had the same GMPP in all topologies, 6 of the 8 cases were the non-shading of all configuration patterns, representing 26.66 %, and (3) The only case where the SP topology had the highest GMPP value compared to the other, representing 3.33 per cent. The power loss of the PV array under partial shading conditions depends on the shading pattern, array configuration, and PV array topology. The results of this study can be used as information to choose the appropriate PV array topology in the future.
