Abstract- a new approach is proposed in this paper to improve the efficiency of solar PV system compensating the effect of irradiance or temperature using MPPT concept (Maximum Power Point Tracking Method). The PV voltage intentional flustering to the changes in PV power which is one of the techniques of MPPT known as Perturb and Observe. And hence we can diagnose the PV characteristics, this unveil MPP position. However the altering temperature (or irradiance) stimulates swing in PV power and a substantial divergence of MPP. The advances for consideration contains an algorithm to reduce the steady state moments and further minimize probability of losing tracking direction of P&O hinged MPPT for PV system. The refashioned program retains conventional P&O, but with unique for swing size. At the same time a dynamic divisions are set to avoid divergence. This work was performed using MATLAB and observed results Keywords— Photovoltaic (PV), maximum power point tracking (MPPT), perturb and observer method (P&O).
