The increasing demand for renewable energy has led to a surge in the development and installation of solar water heating systems. These systems convert sunlight into heat to warm water, reducing the need for electricity. However, for optimal performance, it is essential to conduct a detailed thermal analysis of the solar water heater water heating system to determine its efficiency and potential for improvement.
Thermal performance analysis is a crucial step in designing and optimizing solar water heaters. It involves the study of energy efficiency, to evaluate the system's ability to meet the hot water needs of a building.
The thermal analysis is typically carried out in two stages: the performance evaluation and optimization phase. In the performance evaluation, key parameters such as the solar water heaters' steady-state operation, flow rate, and the temperature distribution of the water are determined.
