“…Previous studies [ 1 , 8 , 10 , 12 , 16 , 18 , 20 ] have evaluated the efficiency on the basis of the average temperature-dependent latent heat of vaporization of the feed water and the average irradiance received by the basin across the productivity hours, as giving in Eq. (4) and usually referred to as daily efficiency (

), where

is the hourly distillate yield, in kg;

is the surface area of the basin, in m 2 ;

is the hourly irradiance, in W/m 2 ; and

is the latent heat of vaporization of water, in J/kg.…”

“…27 Phase change material with pin fin in solar still have significant impact on its performance. Kateshia and Lakhera 28 presented 3E (energy, exergy and economic) analysis of single basin solar still using phase change material with and without pin fins as absorbing materials in three case studies. It has been reported that the energy and exergy efficiency were claimed maximum for the solar still with PCM and pin fins.…”

Water is a vital component of human survival. Drinking water is scarce in several large provinces around the world. Only saline water, which may be demineralised and utilised for drinking, is available in this situation. For extended journeys, normal water is required in boats and submarines. Self–demineralised equipment is usually installed in vehicles, but it consumes more conventional gasoline and is, therefore, more expensive. To address this problem, solar still can be used, which has the primary aim of converting seawater into consumable desalinated water. In this work, a solar still with phase change material (PCM) – RT58 which have better thermo-physical properties has been incorporated and investigated for thermo-economic performance. It is observed from the results that the RT-58 PCM achieved a greater yield compared to conventional solar still (CSS) without any PCM as an energy storage material. The productivity of solar still with PCM is increased by 46% relative to CSS. Also, the economic analysis revealed that the solar still with PCM is more economically viable than CSS in terms of cost per litre production of freshwater and payback period.

“…More advanced studies on desalination have been performed by several researchers-e.g., Ambarita [15], Kateshia and Lakhera [16], Mohaisen et al [17], and Adelgaied et al [18]. Ambarita [15] applied a vacuum desalination system with a low heat source.…”

“…Furthermore, the desalination system used by Ambarita [15] was not simple, and was expensive because the water was evaporated by being heated in a vacuum chamber. Kateshia and Lakhera [16] performed experiments on solar stills using pin fins and phase change material (PCM). They obtained extremely large amounts of fresh water compared to other studies.…”

This study aimed to enhance distilled water production by employing conventional single-slope solar distillers with continuous seawater input. Three solar absorbers—i.e., a flat absorber, an absorber with 10 fins, and an absorber with 15 fins—were designed and examinedexperimentally. The seawater entered the distillers continuously due to gravity. Moreover, the seawater level inside the distillers was kept constant by using a floating ball valve. The overall size of each distiller was fixed at 1136 mm × 936 mm × 574 mm. The performance of the distillers was analyzed and discussed. The average yields of the flat absorber, the absorber with 10 fins, and the absorber with 15 fins were 1.185 L/d, 1.264 L/d, and 1.404 L/d, respectively. The results of the absorber with 15 fins were about 18.5% higher than those of the flat absorber. The experimental results were compared with the established correlations. This new design with increased water yield provides an effective approach for harvesting sunlight in remote tropical regions for small-scale solar desalination.
