Development and implementation of Solar Panel based power management system (original) (raw)

Due to increase demand of electrical energy, solar energy is used to generate electrical energy which is natural source. Although solar energy is available throughout the day its isolation varies from morning to evening and with changing climatic conditions. As the efficiency of solar PV panel is low it becomes mandatory to extract maximum power from the PV panel at any given period of time. Several maximum power point tracking (MPPT) techniques are proposed for the purpose. Incremental conductance MPPT technique has higher steadystate accuracy and environmental adaptability. High frequency DC-DC Buck Boost converter is used to interface PV panel with load and MSP430 controller is used to control the system.
