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

A photovoltaic cell or photoelectric cell is a semiconductor device that converts light energy into electrical energy by photovoltaic effect. A Photovoltaic cell is the building block of a solar panel. If the energy of photon of light is greater than the band gap then the electron is emitted and the flow of electrons creates current [1,2].
