Performance investigation of solar photovoltaic systems integrated with battery energy storage

Solar photovoltaic devices are a clean/sustainable energy resource used to generate electricity in the current era. Overall, the energy yielded from these devices is used to supply the electrical loads in order to meet energy needs. Any building can store electricity produced by renewable energy technology supplies through energy storage using a battery system. This study aims to determine the system’s optimal performance characteristics within solar photovoltaic (PV) systems, including coupling the solar system/inverter and controller/battery storage (BS). This study builds a model using solar simulation in the ‘system advisor model’ programme, utilising a photovoltaic system with the integration of battery storage, which can improve energy efficiency. High-efficiency battery storage is needed for optimum performance and high reliability. To do so, an integrated model was created, including solar photovoltaics systems and battery storage. Energy storage (ES) is a challenge that must be carefully considered when investigating all energy system technologies. The results indicated that the overall system has an annual energy yield of approximately 1,353 kWh/kW and a performance ratio of 0,85. The high energy yield occurred during the summer, owing to more sunshine hours and the high magnitude of solar intensity. The ultimate finding proposes an optimisation framework to estimate/delineate the energy of generation/storage arrangement based on the power potential.
