In the present world there is a lot of increase in energy demand. It is time for us to come up with innovative solutions as we are going short of our available resources. Though the utilization of solar energy is very less compared to other available resources at present, it is going to double in future. This paper describes a technique for extracting maximum power from a photovoltaic panel to charge the battery. We make use of MPPT (Maximum Power Point Tracking) algorithms for achieving maximum power point. The power from the solar panels is fedto charge controllers, which is output to a battery where energy is stored. An inverter is present at the outlet 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. A microcontroller is programmed to always output maximum power. It performs this work by taking input voltage and current from solar panel, output voltage and current from 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 a remote location via RS485 interface so that this functionality aids in remotely monitoring and logging the data.
