Partial shading (PS) condition has a negative effect on the shaded photovoltaic (PV) modules/arrays itself. In addition, it reduces the output power generated considerably. The PV system configuration represents one of the effective solutions to alleviate the PS effects and extract the global maximum power (GMP) available from the partially shaded PV (PSPV) system. This study introduces a detailed performance analysis and comparisons of four proposed PV system configurations [module integrated converter (MIC), multi-strings interfaced interleaved boost converter (MSIBC), multi-arrays interfaced IBC and single array single converter (SASC)] in terms of output power generated and mismatch loss (MML) index. The selection of the best PV system configuration, which not only mitigates the PS effects but also extracts the GMP available from the PSPV system, depends on a trade-off between the generated power, cost and complexity before judging which one is preferable. Although the MIC PV system has the highest output power generated (33 kW) and MML (100%), it increases the PV system complexity. Whereas, MSIBC has the second highest output power generated (28 kW) and MML compared to MIC. SASC has the lowest generated power and MML among the four configurations. The finding proves that MSIBC has superior performance compared to the other PV system configurations considering both the technical and economic assessment.
