Water is an essential prerequisite for the sustenance of life on Earth, and its accessibility is imperative for survival. Numerous scholars have embraced the pursuit of viable remedies for the eradication of water scarcity, with solar distillation emerging as the most uncomplicated solution, particularly in regions with ample sunlight during the early hours of the day. The employment of solar-powered distillation devices represents the most rudimentary method employed to obtain potable water. For this, three identical single slope solar stills are built up; the first is a conventional solar still (CSS), the second is a conventional solar still integrated with copper pipe solar collector (CSS-CPSC) and the third is a conventional solar still integrated with finned tube solar collector (CSS-FTSC). Which acts as a preheating system for evaporation process augmentation. The results show that the CSS-FTSC operates with temperatures higher than those of CSS-CPSC. Also, the yields of the CSS, CSS-CPSC and CSS-FTSC are 2.886, 4.372 and 4.766 L/m2/day respectively. Thus, the productivity enhanced by 51.50% and 65.12% when using FTSC and CPSC, respectively, as compared to that of CSS.
