This study looks at how well a solar still worked in Al Bayda, Libya (32°27'N, 22°37'E) over a 10-day period in August when there was a lot of sunlight. The effect of stone bed thickness (0 cm, 1 cm, and 2 cm) and glass cover angle (22°, 27°, 32°, and 37°) on the water temperature and the amount of freshwater produced was carried out in this research. The results showed that, a 32° glass angle yielded the most water, 15% more than at 22° (10%), and more than 37°. A 1 cm stone bed significantly extended thermal storage and evaporation during low-radiation hours. The best mix of a 32° angle and a 1 cm stone bed increased the amount of fresh water produced each day by 20% compared to the usual setup. The most productive time was between 12:00 and 14:00. These results suggest a cheap way to improve the design of solar stills in dry areas, potentially increasing freshwater production in Libya's AL Jabal AL Akhdar Region.
