Abstract

Water scarcity is an issue that stems from the overconsumption and misuse of fresh water supplies, which leads to shortages and decreased quality of life. It most affects developing countries that do not have the infrastructure in place to mitigate these factors. Solar still become most suitable method for water purification in these types of places due to its cheapness and easily made from locally available materials. Current paper concentrate on a detailed techno-economic and enviroeconomic analysis of distinct configurations of active and passive solar distillation stills. Distilled water production, cost per litres, environmental cost comparison has been done between different types of passive and active solar still. Active solar still has a higher system cost compared to passive solar due to the addition of thermal energy by different components and mechanisms. Based on the results, minimum cost per litre is obtained for passive conventional solar still with the spherical ball as heat storage material and in case of active solar still, with PV module, reflectors, air-cooling technique are 0.0136 $/l and 0.0092 $/l, respectively. On the basis of energy, the highest environmental cost was found for AMSSFS air-cooled with evacuated mode (1456.38 $), while the lowest was found for active solar stills with N - Flat Plate Collectors (44 $).
