Abstract: The need for renewable energy sources is on the rise because of the acute energy crisis in the world today.Solar energy is a vital renewable resource for the power.In this project, we examine a method to extract maximum obtainable solar power from a Photo Voltaic(PV) module.This project investigates in detail the concept of Maximum Power Point Tracking (MPPT) which significantly increases the efficiency of the solar photovoltaic system by using interleaved buck topology. The MPPT is responsible for extracting the maximum possible power from the photovoltaic and feed it to the battery or load via the interleaved buck converter which steps down the voltage to required magnitude. The main aim will be to track the maximum power point of the photovoltaic module so that the maximum possible power can be extracted from the photovoltaic module. The algorithms utilized for MPPT is Perturb and observe method which is easy to model or use as a code.The interleaved buck converter is controlled through ultra low power MSP430 microcontroller and photovoltaic full bridge driver.
