One of the ways for transforming unclean water is by using the solar distillation technique. Evaporation of water and condensation of water vapour are the two key processes in this water filtration process. In a solar distillation system, the heat energy from the sunlight is used to raise the temperature of the unclean water so that water evaporation may take place. The condensate will be collected when the evaporated water vapour has been condensed. Lakes and water reservoirs are some of the examples of unclean water sources that can benefit from having a solar water distillation system. This project presents the design and fabrication of a small-scale passive solar water distillation system, which can be used to generate clean distilled water from lakes located at Seri Iskandar, Perak. The design and features of the prototype will be presented in this paper. The theoretical and experimental performance of the prototype will be calculated and evaluated. It is estimated that a minimum amount of water of 52.3 ml per hour can be generated by the prototype. Nonetheless, a total amount of 225 ml of distilled water was able to be collected on the first day of testing. � 2023 AIP Publishing LLC.
