Abstract: On the basis of experimental results obtained during performance evaluation of five types of solar stills, kept in outdoor conditions on a single plate form, the cost of distilled water produced have been calculated by using a uniform cost analysis method. The experiments were performed at IIT Delhi, India during the years 2001-2002 under summer and winter, both the climatic conditions. It can be concluded that the cost of distilled water produced from a multiwick double slope solar (DSMS) still is lesser than other solar stills due to higher yield/hour. However, for small scale purposes, multiwick single slope solar (SMS) still is a better option.
