“Green Charge: Managing Solar Energy in Smart Buildings”

The evolutions in technology and changes in a lifestyle of people have led to risen consumption of electricity over the period time, with the non- renewable sources of energy-depleting, more focus has to be given to generating electricity from renewable energy sources like solar energy, wind energy, tidal energy, geothermal energy, etc. Solar energy is one of the abundant reliable sources of renewable energy. Buildings account around 40% of the society’s energy demand and it plays a prominent role in the transition to green energy. By making the energy systems of building smarter we can attain further energy saving, flexibility, and huger efficiency in energy management. This paper elucidates a system that extracts maximum current from the solar cell to charge a battery irrespective of the irradiation and duty cycle. The system consists of a synchronous DC-DC buck converter; Maximum Power Point Tracking (MPPT) controller, PID controller, and the system parameters are controlled and handled by LabVIEW software by developing a circuit model on MultiSim software.
