Performance of Photovoltaic Systems Maximum Power Point Tracking

Ahmed Ibrahim,M.M Sayed,Majid Esawi.

The Maximum Power Point Tracking (MPPT) is an instrument which extracts the maximum power available from the PV array at any given moment. The power available from a PV module passes through a peak at a particular operating point and this peak also changes with atmospheric conditions. Hence the changing peak power needs to be continuously tracked.This paper explains the performance of two different MPPT used tosolar modules: perturb and observe (P&O) and incremental conductance (IC). It starts with a description of each method and then it compares them considering capability to follow irradiance variations in the required measurements.
