Abstract – Solar Photovoltaics has proven itself to be the most dependable source for harvesting solar energy.  The output of solar PVsystem relies upon solar radiation and temperature which vary throughout the day.  This caused variations in the maximum power point (MPP) on the solar PV output characteristics curve.  Therefore Maximum Power Point Tracking (MPPT) technique is used to track the MPP and extract maximum power out of the PV systems.  The maximum power is fed to the Buck boost converter to regulate the output according to the load requirement by varying the duty cycle.

Key Words:  Photovoltaics, PV system, solar, MPPT, converter, duty cycle
