Solar photovoltaic (PV) efficiency improvement is critical to the use of largescale power generation. The effects of partial shading are a major source of concern for reduced power generation and increased power loss (PL).Researchers explored an extensive way to resolve the shading issue using the metaheuristic approach for the reconfiguration of PV arrays. In this perspective, a detailed review of metaheuristic approaches involved in PV array reconfiguration solutions to provide improved performance. Furthermore, all metaheuristic approaches are classified as (i) evolutionary, (ii) trajectory, (iii) art inspired, (iv) ancient inspired, and (v) nature inspired. The evolutionary and nature-inspired metaheuristic approaches are used in the application of PV array reconfiguration and are critically studied in terms of ease of implementation of global power maxima under partial shading conditions (PSCs). In this present paper, an experimental study validates the MATLAB/Simulink results investigated under shading scenario for conventional total-cross-tied (TCT) and maximum-minimum tier equalization swapping (MMTES) metaheuristic technique-based PV array configurations. The obtained results in terms of percentage of power gain are 11.88% and 11.52% with respect to TCT in MATLAB/Simulink and experimental studies. Further, this study assesses the potential of each algorithm by comparing it with well-established procedures involved in PV array reconfiguration. This paper examines an important review on the types and nature of objective functions, figure of merits, pros and cons, challenges, and future research opportunities.
