Performance comparison of Zig-Zag and Su do Ku schemes in a partially shaded photo voltaic array under static shadow conditions

Due to shade dispersal, relocation of photovoltaic panels according to Su Do Ku scheme boosted power output of Photovoltaic generator subjected to partial shadowing. Su Do Ku scheme of arrangement is not proper for arrays which has uneven rows and columns. We suggested ZIG - ZAG scheme of arrangement and this structure of pre placement can be executed on photovoltaic schemes with any unequal number of columns and rows. In this paper, ZIG - ZAG structure of placement of panels is compared with standard TCT scheme and Su Do Ku order of placement of panels. These rearrangement schemes are explored for five dissimilar static shading patterns. Circuit connection between modules is not changed in pre placement pattern. The outcomes show that relocated ZIG-ZAG assembly showed better characteristics under shading conditions. This lessens total number of local maxima in power-voltage (P-V) curve and also improved normal voltage of Photovoltaic generator. Thus the maximum power point can be tracked easily in this method of placement of panels.
