The book "Performance Analysis of Roof Top Salt Gradient Solar Pond" offers a comprehensive examination of the use of solar energy through the innovative technology of solar ponds. In recent years, the utilization of solar energy has significantly increased; however, challenges in the collection and storage of thermal energy have arisen. Solar ponds present a cost-effective solution that stores solar radiation in a medium and provides it as thermal energy over extended periods. This study focuses on the construction and analysis of salt gradient solar ponds, which are divided into three layers to maximize heat distribution efficiency. The results indicate that the maximum temperature in the storage area reaches approximately 41.7 degrees Celsius, highlighting the applicability of this technology in various fields. The book is aimed at researchers and professionals engaged in renewable energy and innovative energy storage solutions.
