Abstract

The scarcity of fresh water is a primary problem in remote regions. Thus, an economical and related water distillation solar still coupled with a solar collector was designed and studied experimentally. This study aims to investigate and evaluate the performance of an active single-slope solar still (ASSSS) coupled with a solar evacuated tube collector (ETC) as the water heater. The results showed that the average distillate productivity of ASSSS combined with U pipe solar (ETC) was 1.085 l/m² in December 2020, but 3.12 l/m² in August 2021. These quantities of the water distiller were higher than those of a passive solar distiller with a single slope (PSSSS). The average value of the water temperature increased using the ASSSS coupled with ETC in August 2021 at 79.1°C, whereas it was 71°C in August 2021 for PSSSS. These results indicate that the ASSSS is more effective than the PSSSS.
