Utilization of Stand-alone Solar PV system or Off-grid Solar PV system is one of the availability approaches that can provide the electricity to a rural or remote area which is far away from the national electricity grid or enable to be reach. Theoretically, the successful application of Stand-alone Solar system reached the electricity demand while improving the living condition of local people at that place. The design of Stand-alone Solar system is much complicated compared to the Grid-connected Solar PV system where the design have to design properly with consideration of many factors. For design this system, the energy demand, irradiation to load ratio, system voltage, total load current, day of autonomy, depth of discharge of battery, ambient temperature with temperature correction factor, the limit of parallels stings of batteries factor have to seriously take into account to designing the size of capacity of the battery bank. In designing the sizing of PV array, the temperature derating factor, nominal operating cell temperature (NOCT), dirt factor, over-supply coefficient, coulombic efficiency, peak sun hours, and maximum solar irradiance is very important factors to design the sizing of PV array. These factors are covered in system sizing of design. The purpose of these consideration is to ensure the designed system will operate under design potential without any failure when worse case condition happen at some days and also to maximize the lifetime of the system. The economic analysis of Stand-alone Solar system also be covered to analyze the startup cost and the return of investment. The different between using calculation analysis and using HOMER software while designing the stand-alone solar system also being discussed in this paper.
