An extensive review on different design and climatic parameters to increase distillate output of solar still

Most of the part of the land is covered by saline water where fresh water is available in less proportion and also the demand of fresh water for drinking use is increasing rapidly day after day due to increase in the population. Hence, solar desalination is a feasible alternative to sweep over this massive difficulty. The process by which impure water is converted into clean water is called soar desalination and instrument which is used for it is known as solar still. A lot of investigation has been done by various researchers to inspect the parameters which affect the efficiency of solar still and thereby to improve its performance. In this review paper different design and climate parameters are reviewed which affects the yield of a solar still.
