“…The cumulative distillate water output from the modified solar still increased compared with the conventional solar still by a factor not less than 240%. [17] this study is to be conducted to validate the optimum productivity of purification water by turning hollow-cylinder. Experimental results demonstrated that a basin water height is (1 cm) gives better productivity of (1225 ml/ m2.day) for conventional solar water distillation, and (2 cm) basin water height for the modification solar water distillation gives the optimum productivity, which is (3540 ml/m2.day) which represent an increase of 188% when compared with the productivity of the conventional solar water distillation.…”

The performance of the double-slope solar distiller is combined with two types of solar collectors (vacuum tube solar heater ETC and solar concentrator PTC). The water inside the solar distiller is heated by a heat exchanger linked with the solar heater and the concentrator. 1.4, 1.7 and LPM 2). The results showed that the high temperature of the brine water inside the distillate was obtained at the LPM 2 flow, while the productivity was 2.248, 2.774, and 4.367 liters / day, respectively, for a depth of 0.05 meters of brackish water for the three flows, respectively. The maximum thermal efficiency capacity per hour was 53%. And 51% and 64.1% for water flows of 1.4, 1.7, and LPM 2, respectively. 15.00 hours the thermal efficiency per hour was maximum when the brine temperature was maximum and the base of the tank was at 15.00 hours.

“…The globe is grappling with a scarcity of water owing to industrialization, population growth, and water contamination; hence, it is imperative to investigate alternative decentralized systems like passive solar distillers that rely on renewable sources of energy to cater to the requirements of rural regions, even though their manufacture is somewhat constrained [4]. Clean drinking water may be distilled from dirty sources using solar energy, a sustainable and inexpensive power source that does not contribute to greenhouse gas emissions via the process of solar water distillation [5].…”

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.

“…Notable examples include coal, oil, and natural gas. Conversely, renewable energy, inherently replenished by nature, offer cleaner alternatives devoid of harmful pollutants [1]. Makhzom et al based their research on actual measured data collected over long periods by the monitoring and control systems of the power plants in question.…”

Solar energy is a key renewable energy source. Research and development have focused on enhancing the heat transfer coefficient, heat gain, and practical efficiency of solar systems. The aim of this study is to evaluate the performance of a flat solar panel collector using a nanofluid under conditions in the city of Kirkuk/Iraq, 35° latitude and 45° longitude, in terms of practical calculation of thermal efficiency. The study included making two solar collectors, one traditional and the other improved using a nanofluid (CuO). The CuO/Water nanofluid was prepared with a volumetric concentration of 0.25 % by mechanical mixing and then ultrasonic mixing to homogenise the particles and eliminate the agglomerations that form inside the fluid. Practical testing was conducted for the two solar collectors, one using distilled water and the other using the nanofluid, during four months (January, February, March, and April) of the year 2023. The experiments revealed that the efficiency progressively improves from 9:00 a.m. to 1:00 p.m. This increase is attributed to solar radiation’s decreasing intensity post 12:00 p.m., while thermal storage and minimised thermal losses continue to contribute. After 2:00 p.m., the efficiency dwindles due to the declining solar radiation intensity. The practical efficiency of a 0.25 % nanofluid (CuO) attains its zenith at a mass flow rate of 0.015 ls−1. Higher mass flow rates enhance heat transfer within fluid-filled tubes. The collector efficiency at this flow rate ranges from 31.66 % in January to 44.44 % in April.
