A Simple device which is used to obtain fresh water from saline water with the use of solar desalination process is known as solar still. The simple solar still give an output of 2.5 to 5 litres per 1m 2 area per day during bright sunshine hours. Hence various investigation has been done by scientists and researcher to improve the performance of solar still by inspecting various design parameters(water depth, condensing cover material, its thickness and inclination, type of solar still), climatic parameters(wind velocity, ambient temperature, solar radiation), operational parameters (salinity of water) which affect the production rate of solar still. In this review paper an attempt has been made to evaluate the effect of different design, climatic & operational parameters that affect the performance of solar still.

“…[3] result shows increase in production by 20 %. Evacuated tubes played important role for effective utilization of hot water for the increment in distillate output [9][10][11][12][13]. Yousef and Mousa [20] results also show that, the use of the film-cooling increases the still efficiency up to 20 %.…”

Glass cover is very important component for the efficient design of the solar still. Sunrays are first incident on glass cover and then transfer to the solar still for the purpose of evaporation of water to get potable water. Selection of the proper glass cover is always based on transmittance and it is depends on thickness of the glass cover. Hence, to study effect of transmittance on glass cover thickness, three different thicknesses of glass cover like 4 mm, 5 mm and 6 mm were chosen for the study on three same sized solar stills and tested in composite climate conditions of Mehsana, a city of North Gujarat, India during sunshine hours of January 2011 to June 2011. Theoretical and experimental analysis of three different thicknesses of glass cover is carried out by heat and mass transfer analysis to determine the optimum thickness of glass cover for the effective distillate output from solar still and validation between them. After six months of experiments, it has found that 4 mm and 5 mm glass cover thickness increased average distillate output of 27 % and 12 % compared with 6 mm glass cover thickness. Also theoretical results found good match with experimental results.

“…The latent heat of condensation, increasing distillate output, heated the upper basin. The system with a depth of 0.03 m generated greater distillate, with a mean of 8 and a water value of around 0.37 Rs/kg [4]. This painting offered a solar air-heating device, such as a vacuum tube air solar collector (SC) and latent heat thermal energy storage (LHTES).…”

With the development of solar energy collection technologies and the mechanism of exploiting solar energy as renewable energy, it was necessary to develop a solar vacuum tube system, which is considered one of the old systems with little efficiency. In order for the development process to be completed, it was necessary to place side reflectors that border the pipes from all sides to better reflect solar radiation and raise the temperature of the pipes to the required level. The optimal angle for increasing temperature was determined by adjusting the sidewalls of mirrors, adjusting the wall width, and comparing angles at various angles (30, 40, 50, 60, 70, 80, 90) degrees, to achieve the best results. The angle of the mirrors on the pipes is adjusted from 30 to 90 degrees, as well as their width from 250 mm to 500 mm, and from 5 a.m. to 5 p.m., with a difference of one hour each reading. The temperature gradient on solar collector tubes increases with time and mirror angle, reaching maximum at noon and 30 degrees. Infrastructural radiation increases significantly at 30 degrees, reaching 700 W/m 2 . The width of the mirror wall affects radiation reflection and distribution, with a 500 mm width being more effective. The 30-degree angle had the highest thermal efficiency at 84%, while a 500 mm width difference achieved 86%. The novelty of the work varies in terms of developing the thermal efficiency of the solar collector by adding these influential factors to it.
