and high capital cost. “Solar Panel Maximum Power Point Tracker”. As the name implied‚ it is a photovoltaic system that uses the photovoltaic array as a source of electrical power supply and since every photovoltaic (PV) array has an optimum operating point‚ called the maximum power point‚ which varies depending on cell temperature‚ the insolation level and array voltage. A maximum power point tracker (MPPT) is needed to operate the PV array at its maximum power point. In this thesis‚ we examine
