Maximum power point tracking (MPPT) is an important concern in the operation of photovoltaic(PV) systems. Each PV cell have
some particular efficiency at converting the energy in solar energy into electrical energy. Moreover the PV cell exhibits non linear
power-voltage and non linear current-voltage that means there is a single operating point which corresponds to maximum power and
efficiency. When number of cells are connected in series and parallel arrangements the characteristics of a I-V and P-V becomes
more difficult and exists more local maxima. A PV source has the advantage of low maintenance cost and absence of extra rotating
parts.
