Effective Use of PV Systems for a Sustainable Energy Solution: A Case Study

Energy demand is rapidly increasing alongside global population growth. Instead of relying on fossil fuels, which harm the environment, technological advances have enabled the use of renewable energy sources. Solar energy is increasingly recognized as a vital resource among many renewable options, and its usage is expected to grow even more in the future. Photovoltaic (PV) solar panels enable detached houses, especially in remote settlements, to meet their electricity needs. The most important component that converts the energy produced in this PV system to the desired level is the DC-DC converter. One of the most effective methods to obtain the highest amount of power from the PV panel is the application of the Maximum Power Point Tracking (MPPT) technique to the DC-DC converter. Additionally, battery systems have proven to be a viable solution for meeting energy demand during periods when PV panels do not produce electricity. In this study, an efficient working structure has been developed using the MPPT algorithm to meet the load's needs while storing a portion of the electrical energy obtained from five parallel-connected PV panels in a lithium-ion battery. Ensures an uninterrupted energy flow at the highest power output using the most appropriate technique. MATLAB/Simulink software was employed for system design and simulation. Solar radiation data from the summer period of the Enez district in Edirne province were selected for analysis. A lithium-ion battery type was utilized in the system. The results show that energy from the PV panel is insufficient during the early hours of sunrise, at which point energy demand is met by the battery. After a certain hour, the PV panel satisfies the required energy demand, and any excess energy is stored in the battery. This system demonstrates an efficient energy management structure that ensures continuous power supply for off-grid households.
