ABSTRACT=There has been a global expansion of solar electricity during the past decades. Solar photovoltaic (PV) electricity generation is not only simple but also environmentally benign and cost-effective. This is most affordable and suitable power source for the rural areas. PV power output is unavoidably suppressed when there is partial shade. There were numerous MPPT, array, and reconfiguration approaches that were available in earlier times. The authors have previously described an L-shaped propagating array arrangement. The L-shape configuration creates the PV rows based on the chess game coin. The knight coin of this game will move in the shape like "L", that is inspired on new array configurations. This work discusses the hybridization of the L-shape configuration with the conventional array configurations. The proposed hybrid L-shape configuration has been developed in a MATLAB/Simulink, where the conventional configuration and the hybrid configurations are validated in the different test conditions. The test conditions are created based on the all possible realword shading patterns. The power generation, mismatch losses and characteristic curves were attained for each method and this work presents all these validations with the inferences. Also, the justification for the suitable array configuration with
