RECONFIGURATION OF SOLAR PANELS TO PRODUCE MAXIMUM POWER USING NOVEL METHOD (TOUR PUZZLE)

Abstract

This paper introduces a new reconfiguration technique called tour puzzle for better shadow dispersion and obtaining maximum output power under partial shade conditions. In the presented method, partial shadows are spread in all rows and maximum power can be achieved. The puzzle tour can be applied to all kinds of PV arrays of different dimensions and sizes. Accordingly, the puzzle tour procedure is applied in several cases in the form of squares and rectangles with different dimensions and various shading conditions in each case. To directly compare and present the efficiency of the proposed method, the total cross-connection model and conventional methods such as magic Square puzzle, competence Square puzzle, Skyscraper and improved Sudoku are also implemented in the introduced cases. Finally, the evaluations emphasize the capability and efficiency of the Tour puzzle solution compared to other methods by achieving GMPP values such as 63.9 VmIm, 69.3 VmIm, 69.3 VmIm and 68.4 VmIm for cases 1 to 4, respectively. The results show that the proposed method can provide acceptable performance for solving the problem of achieving maximum power under PSC in PV.
