This paper discussed the experimental performance of a solar still with cylindrical hollow fins that were integrated�to a black painted stainless-steel basin. The cover of the solar still was made of transparent polythene film, while�the frame was made of polyvinyl chloride (PVC). Mild steel cylindrical hollow pipes of 0.035 m diameter were�used as fins in the solar still. The performance of this solar still (PSSCHF) was compared with the performance�of a conventional solar still (PSS1) which was made of similar fabrication materials, but without using fins in its�basin. Each solar still basin contained water with the depth of 1 cm that was collected from a pond located at the�Universiti Sains Malaysia (USM) campus. Both PSSCHF and PSS1 solar stills were exposed to similar climatic�conditions within the same locality at USM during the experiments. The purpose of using the fins in the basin�of PSSCHF was to absorb more heat from solar irradiance. The PSSCHF attained a maximum productivity of�4.49 l/m2·d, whereas the PSS1 obtained a maximum water production of 3.97 l/m2·d. The quality of fresh water�produced from the solar stills met the World Health Organization potable water standards. © 2020. The American Society of Hematology. All Rights Reserved.
