    Abstract: On scrutinizing P vs. V curves of P_V arrays
which receives non_uniform insolation of light or simply
during Uneven_Lighting_Conditions (ULCs) multiple
LMPPTs are exhibited. Conventional MPPT methods are
efficient in normal conditions even though they failed to
identify the GMPPTs from LMPPTs under ULCs. To
improve productivity of Maximum_PPT method for P_V
arrays under both ULCs and normal conditions
some modifications are tried in this study. The
Incremental_resistance_method added with some
alterations enables to track the LMPPTs as well as
GMPPTs very effectively and accurately with less
numbers of steps. In proposed system, losses during
GMPP tracking is minimized under ULCs. Simulation is
performed in MAT_LAB.
