The power loss in the arrays due to non-uniform irradiances site is most common scenario observed a PV system. irradiance non-uniformity occurs obstacles between actual and modules caused by dust shadow of clouds, trees, buildings some portions array. This results complications like mismatch, reduction, deformed characteristics curves, failure tracking algorithms, sometimes physical damage modules. Numerous solutions are present for mitigating above among which array reconfiguration gained huge audience ease implementation, lower cost, higher reliability but, each technique exhibits certain drawbacks. In this paper, harmony search (HSR) algorithm dynamic proposed that has advantages terms simplicity, adaptability, convergence speed, reduced switch count, arbitrary application. modeling validation done MATLAB platform using 5x5, 9x9, 9x5, 3x3 under various shading cases compared with 22 existing conventional, static, techniques. depth investigation shows performance HSR 24.64% 12.28% than conventional static techniques lowest deviation -1.10% equivalent complexities.
