A design of cost effective hybrid solar interface and management unit
AbstractElectricity is the common problem in many countries and to fulfil the requirements of people in these countries a system is designed which use sun light to generate electricity. This system requires solar panel to convert sun light into dc voltage and then start working and charge the dc bank and then electricity is generated by inverters. By using this system we are having full control on grid supply. If according to the requirement of user power from solar panels is available then solar management and interface unit cut the mains from the inverter and load runs through the power generate by solar charge controller from solar panels. And system check time to time for the power required by user and generated from solar management and interface unit using solar panels. If there is a difference in available power and required power then microcontroller switch the system to mains mode. And also check again and again if at any time power from solar is equal to the requirement then again mains cut and system starts its working and also charge the batteries used by the system. And if current is available from solar panels but less than the requirement in such a case the available power from solar side is utilize to charge the batteries only. 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.
