The material that can be used to generate power is depleting on a daily basis, the demand for renewable energy sources is increasing, owing to the current global energy crisis. In recent news, it has been reported that India is running out of coal, forcing us to switch to renewable energy sources such as solar and wind. In this project, we look at a design for extracting the highest amount of solar electricity possible utilizing MPPT techniques (Maximum power point tracker). We will convert and introduce the boost converter in this project, such as the boost converter, which enhances the voltage. The boost converter's premise is that the output voltage is higher than the input voltage, i.e. (Vout>Vin). Our boost converter is designed to convert the solar panel's 12-volt output to 24 volts, which is then applied to the battery. The output of the solar panel is regulated by a microcontroller unit that employs the voltage feedback approach. To safeguard the microcontroller from damage, voltage feedback is utilized to transform the 12 volts to a range of 0-5 volt. We can continuously monitor and measure the boost converter output and pass it to the microcontroller to generate the pulse width modulation (PWM) signal. This can affect the boost converter's duty cycle, therefore MPPT is a technology that tracks and monitors the solar panel's maximum power before delivering it to the load.
