“…Direct solar desalination systems, also known as solar stills, distillate is produced directly in the solar collector, whereas in indirect solar desalination systems, solar energy is harvested as thermal or electrical energy which in turn is used to drive desalination. Despite many advances in enhancing the productivity of solar stills as can be found in recent reviews [10,[29][30][31][32][33], currently available designs are still not suitable for large scale water production [34]. However, in the last two years, research in new materials for direct solar desalination has rapidly advanced, as will be seen in Section 3.…”

“…In a solar still, saline water is evaporated directly by solar energy and then condenses as distilled water [63]. There are several review articles available in literature focusing on advances in solar still productivity including operating conditions and design configurations [29][30][31]33], as well as solar stills with latent heat storage for use in the absence of sunlight [32]. Current solar still designs are still not suited to large systems [64].…”

Growing water demands have led to rapidly increasing desalination installation capacity worldwide. In an attempt to lower carbon footprint resulting from high-energy consuming desalination processes, attention has shifted to using renewable energy sources to power desalination. With solar irradiation ample in regions that heavily rely on desalination, solar powered desalination provides a sustainable solution to meeting water needs. The compatibility of each desalination process with the solar technology is driven by whether the kind of energy needed is thermal or electrical, as well as its availability. With rapid advances in solar energy technologiesboth photovoltaic and solar thermal, there has also been growing interest in coupling solar energy with desalination, with a focus on improving energy efficiency. In this review, the most recent developments in photovoltaic powered reverse osmosis (PV-RO), solar thermal powered reverse osmosis (ST-RO) are discussed with respect to membrane materials, process configuration, energy recovery devices and energy storage. In addition, advances in new materials for solar powered membrane distillation (MD) and solar stills in the past two years have also been reviewed. Future outlook considers the use of hybrid renewable energy systems as well as solar powered forward osmosis and dewvaporation. Solar powered desalination systems have been analysed with emphasis on technological and energy consumption aspects.

“…Although a major percentage of surface of the earth is made of oceans, but its high salinity make it unsuitable for human consumption as well as industrial usages . In recent years, an exponential rise in pollution of water bodies due to an increase in industrial discharge as well as dumping of human and animal waste have left fewer sources of water available for direct consumption . In urban areas, the levels of underground water have also been severely affected.…”

A novel experimental approach is presented where studies have been conducted on a solar still at four specific heights in the range of 0.266–0.341 m (in steps of 0.025 m) keeping other dimensions constant. Performance of solar still is established under indoor environment to suppress meteorological factors. Uniform heat was supplied to the solar still through flat plate‐type electrical heaters. For each specific height, the performance of the solar still was evaluated at five heat fluxes (600–1000 W/m2 in steps of 100 W). Performance of solar still at different specific heights was compared in terms of operating temperatures, productivity, and efficiency. It was found that reduction in specific height enhances distillate productivity as well as thermal efficiency of the solar still due to reduction in cavity volume and an increase in average operating temperature. An increase of in daily distillate yield of 89.44% (at 600 W/m2), 56.07% (at 700 W/m2), 28.50% (at 800 W/m2), 38.60% (at 900 W/m2), and 37.38% (at 1000 W/m2) between Case 1 to Case 4 was observed. Further, between Case 1 and Case 4, the thermal efficiency increased from 27.29 to 46.18%, 32.73 to 51.06%, 36.82 to 52.17%, 41.25 to 56.79%, and 42.55 to 57.50% at 600, 700, 800, 900, and 1000 W, respectively. Results demonstrate that for a particular specific height the total daily productivity increases linearly with heat flux. Correlation for estimating thermal efficiency of solar still is proposed in terms of the aspect ratio and input power. © 2019 American Institute of Chemical Engineers Environ Prog, 38: e13227, 2019

In this paper, mathematical model for the conventional solar still was established. Numerical solution for the model has been performed using MATLAB software. The main objective of this research is to compare the hourly distillate produced from the conventional solar still resulting from the present numerical solution with the measured hourly distillate of other researcher in order to validate the mathematical model. The results show good agreement when comparing the numerical solution results and the experimental results on 25 May 2013 for operating hours from 9:00 a.m. to 17:00 p.m. in Kafrelsheikh, Egypt.
