Progresses in inclined type solar stills

Basin type solar still is a simple device which can be used for fresh water production. The main drawback of a conventional basin solar still is the low amount of distilled water production per unit area which makes the single-basin solar still uneconomical. In inclined still, higher surface area and thin water surface are its advantages and maintaining continuous wetness along the inclined surface and loss of heat through raw water drain are the problems. This work reviews different methods used to improve the effectiveness on the inclined solar still so far by different researchers and compare their performances. (C) 2012 Elsevier Ltd.
