Abstract

Potable water is essential for human existence. In addition, the quantity of potable water is limited. On the other hand, saline water is available, but it is not considered potable. Solar energy is utilized to convert saline water into potable water through a process called solar desalination. Solar stills are devices used to convert saline water into potable water using solar energy; however, the quantity of potable water produced is low. This review paper shows the use of evacuated tubes to increase the water temperature and hence increase the potable water from solar stills. Various researchers have worked on solar stills with evacuated tubes, as discussed in this review. The study concluded that evacuated tubes are among the most crucial components for increasing the amount of drinkable water produced by solar stills.
