“…Wind velocity's impact on the glass cover's surface accelerates the condensation process, which gives higher productivity. 57 Figure 4 depicts the variations in different temperatures. During the experimentation, the observed maximum ambient temperature was 39.2°C at 14:00 h. It was reduced gradually as solar irradiation reduces during evening hours.…”

“…The increase in solar irradiation and productivity reduces the CPL and PBP considerably. 57 Table 3 presents the exergoeconomic parameter in the lifespan of 10 years and interest rates of 12%. As observed, the exergoeconomic parameter in the MPSS with exergy and energy base was higher than CSS, due to high freshwater production of the solar desalination with magnetic powders as an energy storage media.…”

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.

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.
