| Summary: | This study presents the development and performance evaluation of an improved solar still incorporating a solar collector (metal plate) into a monoclinic solar still design. Comparative analysis was conducted between the improved system and a traditional solar still under identical operating conditions. The results demonstrate significant improvements in productivity and efficiency with the improved solar still. Specifically, the improved system achieved a cumulative productivity of 4.5 L/m2, representing a notable increase compared to the 2.9 L/m2 produced by the traditional still. Moreover, the daily efficiency of the improved solar still reached 41%, substantially higher than the 26.7% efficiency of the traditional design. The enhancement rate of 55.17% underscores the considerable performance advancement attained with the upgraded solar still. These findings highlight the efficacy of integrating a solar collector into the monoclinic solar still design, offering promising prospects for improved solar desalination systems.
