The photovoltaic (PV) system is a clean and renewable energy that convert sunlight into electricity. The demand of PV systems in Malaysia is less significant with only 20% of electricity generated by renewable energy. Typically, high start-up results are obtained from the establishment of a PV framework. The rural zones in the country are unable to reach the power grid and therefore, the proposed strategy will certainly suggest a potential fixation for the issue. This paper presented the optimization of the size of PV arrays and battery for a single-phase standalone PV system (SAPV). The construction of the system starts with the calculation of a single-phase household load demand with high solar irradiance sources and exposed seaside location which can extract more sunlight in an open area. This work implements the use of Homer Pro software and MATL.AB (Simulink). Irradiance data is obtained from SOLCAST website and instigated in the design of the proposed SAPV framework Homer Pro software supports in optimizing the size of the battery storage and the PV module needed using load demand value specified in this work. MATLAB (Simulink) is used to design and simulate the proposed SAPV. This study showed a single-phase S.APV system with battery is successfully designed and simulated using both software tools. The outcomes can be used to confirm feasibility of the proposed methods towards the implementation of PV in rural areas. © 2023 IEEE.
