Abstract

Water scarcity is an escalating global issue which also affects Poland. One of the solutions to this challenge is seawater desalination, particularly using solar stills (SSs). SSs offer a sustainable, low-cost solution for desalination, but their efficiency depends mainly on local solar conditions. Therefore, this study presents long-term experimental results for a single-basin, single-slope SS’s performance in Krakow, Poland, from May to September 2022. The findings show that the SS effectively removed over 98% of total dissolved solids, with a productivity ranging from 1084 to 5014 mL/(m 2 ·day) and water temperatures reaching up to 80.4 °C. These results highlight the feasibility of solar-powered desalination in Poland and contribute valuable data for future optimization.
