“…By estimating the life cycle cost (LCC), the full economic analysis is explored to show the effect of using the solar concentrator or/and the internal reflectors on the total cost of freshwater yield produced from the four solar distillers. The total freshwater production cost per kilogram (TFPC/kg) is calculated using the following equations [17,26].…”

Solar distillation is one of the oldest and simplest technologies for desalination of salty water using renewable energy, namely solar energy, and the main problem of solar distillers is the low freshwater yield in contrast to the amount of energy input from the sun. To overcome the problem, this study develops three solar desalination units by using solar concentrators or/and internal reflectors, and compares the performance of three developed systems with the one of a conventional solar distiller under the climatic conditions of the Rabat region of Morocco. The three systems are: the solar distiller with a solar concentrator, the solar distiller with internal reflectors, and the solar distiller with a solar concentrator and internal reflectors. The energy balance equations of the systems are numerically resolved to utilize MATLAB software. The findings indicate that the utilization of the internal reflectors, the solar concentrator, and the solar concentrator and internal reflectors give better performance compared to the conventional solar distiller.

“…With a distillate of 3.27 kg m −2 , the productivity and energy efficiency increased by 37.5% and 38%, respectively. In the Coimbatore climatic conditions, Dhivagar et al [ 35 ] discovered an increase in productivity in a coarse aggregate sensible heat storage bed assisted solar still. The input saline water was preheated using coarse aggregate and a copper tube heat exchanger.…”

“…Because of the lower increase in annual productivity, the maximum value of the CPL was achieved in the coarse‐aggregate‐assisted solar still. [ 35 ] Similarly, the minimum CPL value for the thermoelectric‐module‐assisted solar still [ 102 ] was obtained as a result of a much lower investment in high annual productivity.…”

The supply of potable water is insufficient to meet the needs of the growing population and daily life. Due to high salt concentrations, ocean water cannot be used directly. Furthermore, the water in rivers and lakes is contaminated with industrial wastes, making it unsafe to drink. A solar still is a simple device that uses solar energy to purify saline water via evaporation and condensation. Solar stills have undergone various modifications to improve the daily productivity. Herein, an attempt is made to categorize the various types of auxiliary components, such as biomass heat sources, gravel bed sensible heat storage, heat pipes, heat pumps, solar collectors, and ponds, assisting in solar stills to improve the daily productivity and energy efficiency. The review outcome shows that the improved daily productivity and energy efficiencies are about 231% and 65% higher than for conventional solar still. Furthermore, in economic analysis, the maximum annual productivity and cost per liter of distillate are about 5845.3 kg m−2 and 1.93 USD, respectively. The maximum payback period is estimated to be 23.9 years. The review also suggests the vision to identify the future scope for additional implementations.

The use of different energy storage materials can have a high effect on the water productivity of solar desalination. This study evaluates the impact of magnetic powders on modified solar still (MPSS) performance and compares the results with conventional solar still (CSS). Black iron oxide magnetic powder was selected to increase solar radiation absorption. The black iron magnetic powder simultaneously acts as a thermal storage material and a porous absorber medium. The thermal energy stored in the magnetic powder improved the performance of the MPSS during peak solar irradiation hours, resulting in higher productivity. The results showed that the thermal performance of MPSS was higher than CSS. The MPSS exhibited a 39.8% higher evaporative and 14.5% higher convective heat transfer rate compared with CSS. Results showed that the cumulative water productivity of MPSS was 31.2% greater than CSS. Also, the energy and exergy efficiencies of MPSS were improved by 18.9% and 19.04%, respectively, compared with CSS. Moreover, the predicted payback period in MPSS and CSS were 3.2 and 4.3 months. Additionally, the CO 2 reduction of MPSS was improved by approximately 45.53% compared with that of CSS. The results also showed that the exergoeconomic parameter of MPSS and CSS with energy base was equal to 33.1 and 24.56 kWh/$, respectively.
