Solar Energy Utilization for Domestic Lighting

In the present scenario, solar energy as a source of renewable energy is used to satisfy the increasing energy demands. The Photo Voltaic (PV) panel is used as the major supply of power and the battery is used as the substitute supply of power for the suitable power converter in the present work. The proposed power converter has the potential to operate at four different states which mainly focuses on the solar power availability, battery charge level, and requirements of the load. A proposed control method uses the P O method to achieve Maximum Power Point Tracking (MPPT). A LED lamp is used as a load, which gets the power either from battery or PV or from both based on the state at which the power converter operates. The simulation of the overall system is shown through MATLAB/SIMULINK. © 2021 IEEE.
