Solar Panel Using Maximum Power Point Tracking

Today’s world there is a lot of increase in energy demand. Now it’s time for us to come up with innovative solutions. The utilization of solar energy is very less compared to other available resources at present. It is going to increase in future. We are going to describe a technique for extracting maximum power from a photovoltaic panel to charge the battery. The power from the solar panels is applied to charge controller which gives output to a battery where energy is stored. An inverter is present at the output of battery to access stored power. A DC-to-DC converter is present inside the charge controller to match the PV module voltage to battery voltage. Microcontroller is programmed to always output maximum power. It performs its operation by taking input & output voltage as well as current from solar panel and DC-to-DC converter, irradiance levels from light sensor and temperature from temperature sensor. An additional feature here is to transmit the data from the microcontroller to location via serial communication interface.
