Solar distillation process is one of the methods to purify water. This water purifying method consists of two main processes, which are evaporation of water and condensation of water vapor. In a solar distillation system, the system utilizes the solar energy from the Sun to heat up the temperature of the dirty water for water evaporation to occur. The evaporated water vapor will then be condensed, and the condensate will be collected. In this paper, a passive solar water distillation system or also known as solar still was designed and developed to produce clean water. The design requirements of designing a solar still with improved efficiency were discussed. The experimental performance of the prototype was evaluated for seven days. The solar still prototype managed to produce a daily average of 897 ml per day of clean distilled water. � 2023 AIP Publishing LLC.
