Water and energy are the two most important factors for the sustainability of life. Less than 1% of the water is directly usable by society, the largest percentage of which is polluted by intractable industrial development. Solar distillation is a potential solution for producing portable water using a device called a solar distiller, viable in remote areas where solar energy is abundant despite severe freshwater scarcity. Decades of global experience in solar stills research and marketing have laid the comprehensive foundation for the solar stills industry. In this publication, comparative performance of various designs of active solar stills in terms of design, efficiency, and power output per m2 solar still was performed. The numerical calculations are based on the experimental performance of still images of the sun reported by various researchers. Average annual productivity estimated from different types of solar distillers on 300 sunny days per year. Energy efficiency and production costs based on life cycle cost analysis were also estimated.
