Abstract: He output power from the solar panel varies with solar irradiance level, temperature and load. In order to increase the efficiency of power extracted from the solar panel, it is necessary to operate the photovoltaic (PV) system near the maximum power point (MPP). There are different types of maximum power point tracking (MPPT) methods. This paper proposes a novel approach for tracking MPP. In this approach it tracks the MPP using normal perturb and observation method, the current-voltage curve corresponding to each MPP is obtained and stored. Whenever a new single data value is read, the algorithm finds which curve has maximum points nearest to the new value and assigns the voltage corresponding to the curve’s MPP.
