Based on the basic principles of thermodynamics, and heat transfer, this paper presented a model of a solar water heating system (SWHS) with the aim of improving on the performance of the system. The annual thermal performance of the SWHS was simulated on the TRNSYS platform. The typical Babylon weather situations, the fluctuations in water temperature within the storage tank, and the inlet and outlet temperature of the collector were investigated. Other parameters considered by the simulation include the sum of solar emission and the difference in heat collector efficiency. The development of a model simulating the SWHS is key to determining the parameters for operating the components. It makes room for selection of necessary parameters required in improving the overall performance of the SWHS. This study provides theoretical guidance for operating the solar hot water system.
