Besides fossil fuels, solar power is one of our most important alternative sources of energy. Extensive studies on photovoltaic systems have been carried out in order to make solar energy more efficient, cost effective and secure. One major way to extract solar energy is by photovoltaic array. However, photovoltaic array is a kind of unstable form of power source, whose power output varies with different environmental condition. A Peak Power Point Tracker (PPPT) is a device which can extract the most out of the PV array.

The purpose of this project will be designing and building peak power point tracking device. Series of intensive testing and analysis was carried in order to optimise the potential and efficiency of a PPPT.

A PPPT utilised here was a step up dc-dc converter, optimised for a nominal input of 40.586W and a 24V Lead-Acid battery as a load. A PIC16C73A microprocessor is employed as a control unit. With appropriate design and implementation, a PPPT with efficiency as high as 97% could be achieved.
