Due to population, industrial, and agricultural growth as well as the rising demand for potable water, there is currently shortage of water in many region of the world. Desalination of brackish and salty water is one of the simplest and economical processes to convert it into potable or drinkable water. But solar still has a low productivity device as its main flaw. Mechanisms for heat exchange play a significant part in increasing the daily yield. The output of any solar desalination system is influenced by the water temperature. The productivity rises as the basin's water temperature rises. A series of experiments were conducted for four different cases in the current study, and it was discovered that the still combined with a parabolic concentrator and stepped basin is the most productive and efficient. The results were verified using mathematical modeling, and it was discovered that in all of these instances, the percentage RMS values range from 10% to 40% and the coefficient of correlation is varies in between 0.8 to 0.99. The overall thermal efficiency of 16.54% is obtained for the integrated system when coupled with evacuated tube collector.
