Renewable energy systems for residential in Australia are developing rapidly in this decade, especially, in South Australia location. There are two the most popular renewable sources which solar and wind. However, there are more. Solar energy is utilised by households to a greater extent than wind energy, even in regions characterised by flat terrain and elevated areas. However, in windy conditions such as high-altitude locations, wind power systems can bring an abundant amount of energy to users. This study examines the analysis and comparison between two practical models of rooftop solar photovoltaic (PV) - battery energy storage systems (BES) and wind turbine (WT) - battery energy storage systems (BES) for grid-connected house (GCH) of two different locations in Adelaide – South Australia. In this project, two system configurations, PV-BES and WT-BES were analysed by choosing the most efficient materials and developing the system simulation in MATLAB/Simulink to generate the maximum energy. During the analysis process, the practical model for each system was established with the actual input weather data, which are solar insolation, temperature, wind speed; in two locations, the materials’ specifications on the market, grid constraints and annual electricity demand. Therefore, the simulation models show the total power supply by renewable sources, the battery state-of-charge and the total import and export power of the system to the grid. Moreover, based on the power flow of systems, a precise cash flow analysis of each system is calculated based on three types of the electricity rates which are time-of-use, anytime tariff, and feed-in-tariff. Hence, the cost of electricity (COE), total payment of customers in one year and system capital cost are calculated. As the result of power flow, and cash flow of each system, the comparison between two system in each location is presented. Finally, the results demonstrate a comprehensive sight of advantages/disadvantages of both systems based on the type of area, hence, the customers have the advises in choosing their add-on renewable system for their house.
