“…The utilization of square, hollow fins and a single-slope solar distillation device yielded a remarkable 40% boost in productivity, achieved by attaching the fins to the absorption plate. Moreover, the introduction of glass cooling, performed either through continuous water spraying or pulse cooling, further enhanced productivity, with the optimal timing determined to be (30 seconds/10 minutes), resulting in a significant improvement ranging from 13.3% to 36.7% [67]. An evaporative cooler is used to cool the solar distiller's glass cover.…”

On a worldwide basis, freshwater is becoming increasingly limited, particularly in dry and distant regions. This presents a complex problem for regions such as islands, where the transportation of water that is suitable for drinking is expensive. In order to address this dilemma, the primary focus of the 21st century ought to be on boosting water purification through the use of renewable energy technology in the desalination industry. To be more specific, the incorporation of solar energy into the business has the potential to extend the lifespan of units, reduce expenses, and reduce the positive impact on the environment. The article contains a sufficient number of studies on a variety of passive and active stills, and it offers an understanding of the effectiveness of each form of still. Vacuum tube solar stills are more efficient than others. In addition to this, it investigates several approaches to cooling the glass cover and the elements that influence the productivity of solar stills, among which are environmental and design considerations. Resolving the problem of diminishing freshwater resources and integrating solar energy for water purification.

Water scarcity is a global concern and poses significant problems to countries with arid and semi-arid climates, like Iran. Considering financial difficulties, a lack of knowledge about high-tech alternatives, low incomes, a lack of access to high-tech tools, and low maintenance capabilities in developing countries, solar still desalination is a decent technology for providing proper water, especially for rural areas. However, the low water-production rate using this method dictates a very vast area requirement for solar still farms in order to provide significant amounts of water. In this research, we proposed a mirror-enhanced solar still and mathematically compared its water-production rate to that of conventional ones. In comparison to conventional solar stills, our proposed reflector-enhanced solar still benefits from several improvements, including lower glass temperatures, increased water basing temperatures, and receiving much more solar irradiation. Hence, the proposed system can increase water production from 7.5 L/day to 24 L/day. The results showed that the proposed method is highly effective and could be used in field-scale projects in arid and semi-arid climates.

“…Another advantage of renewable energies is that it is applicable in remote and underdeveloped regions, where there is no supply of conventional energy (Chen, and Xie, 2022). Solar energy is the best alternative source for heating in distillation, mainly because of its availability and low consumption of energy resources (Hameed, 2022). It uses the principle of the hydrologic cycle, where evaporated water rises and cools down by the wind to its dew point to produce freshwater as rain (Lal et al, 2017).…”

Performance evaluation of a multi-stage solar distiller associated with Fresnel lens in Malaysian weather

Water scarcity is widely known as one of the major current issues. As of now, many solar distillers are using the same concept of evaporation and condensation of saline water to produce distillates. The main problem with such solar distillers is their low productivity, as the latent heat produced is lost to the surroundings. A multi-stage solar distiller can solve the issue of productivity by utilizing the latent heat released. This design consists of multiple solar distillers stacked one on top of the another, producing distillates in each stage while having the same amount of energy intake. Malaysia falls within the tropical belt where solar radiation appears to be diffused, resulting in low-quality heat energy that can be absorbed. To solve this problem, concentrated solar power (CSP) technology has been introduced. However, CSP technology can be very expensive, thus using a Fresnel lens as a direct refraction device will be a cheaper option. In this study, a four-stage solar distiller system integrated with the Fresnel lens is introduced. It was found that the productivity and efficiency of the multi-stage system were higher, with a productivity of 0.164 g/kJ and efficiency of 39.5% when compared with the single-stage solar distiller with a productivity of 0.104 g/kJ and an efficiency of 23.5%.
