Abstract

The current challenge of human society is to meet the large demand of freshwater which is depleting at a faster rate due to a rapid rise in human population and fast urbanization. Solar still is the economical way to obtain fresh water since it solely requires the energy from the sun alone for its operation which is abundant and freely available in nature. The condensed rate of fresh water production stands as a hurdle in effective implementation of conventional solar still. The design factors considered while designing the still to enhance the productivity are an inclination of the glass cover, the area of absorber plate, a free surface area of water and depth of water. The major constraint in conventional solar still is to maintain a large surface area of water with minimum water depth. The best solution for the above constraint is to prefer Inclined solar still in which the surface area of water is large with minimum water depth. In order to improvise the performance and efficiency of inclined solar still, numerous works have been incorporated by increasing the free surface area of water. In this review, an attempt is made to analyze the present status of different designs in inclined solar stills to motivate further research in inclined solar still technology for meeting the demand of fresh water.
