Solar Stills: Review

Abstract

Solar stills are simple, economical apparatuses that harness solar energy to cleanse water by evaporation and condensation. This research study examines solar stills' principles, types and designs, highlighting their significance in mitigating water shortage, particularly in desert and isolated areas. Critical performance metrics, such as thermal efficiency, water production, and material selection, are examined to ascertain the determinants affecting their efficacy. The analysis further addresses creative improvements, including using phase change materials (PCMs), nanotechnology, and hybrid systems that merge solar stills with other renewable energy sources. Additionally, the article assesses the environmental and economic ramifications of solar stills and traditional water purifying techniques. The results elucidate the obstacles and potential for enhancing solar still designs, rendering them a feasible alternative for sustainable water production amid worldwide water scarcity.
