Abstract

In this paper, the embodied energy, pay-back period and cost analysis of triple slope solar still (TSSS) are studied which is compared with the double slope solar still (DSSS). The embodied energy is an important factor in determining optimum material for solar still whose value depends on local availability of materials and their manufacturing processes. The total embodied energy of TSSS comes out to be 3297.35MJ. Energy pay-back time is 0.251 years and the total cost for constructing TSSS is Rs. 14049. The TSSS embodied energy comes out to be 9.28% less than double slope solar still. EPBT of TSSS comes out to be 153.7 % smaller than of DSSS.
