Abstract

Highlights: This work presents a state-of-the-art review of the passive solar stills. The single-basin cascade solar system is still the most appropriate design. Tubular stills with wicks are the most suitable design for industrial purposes. Multiple-basin and multiple-slope passive solar still shows 85 percent yield productivity. It is more efficient to use a hemispherical condenser cover type solar still as opposed to a hemispherical basin type solar still. Abstract: The efficiency and distillate output of traditional passive solar till is poor. Various investigators and researchers have modified the design components of passive solar still to enhance the performance and productivity. The influence of several changed designs is investigated in this study. It is seen that Fresnel lens integrated with single-slope single-basin passive solar still increases productivity by 638.02% and proved to be a superior design among all the design modification. Hybrid solar, when combined with a PV/T collector, increases production by 370 percent. A tubular design with a semi-circular trough packed with black fabric and consisting of connected to an external reflector shows the most significant improvement with 676 percent. This review shows that wick coupled with tubular solar still is most productive design for industrial application, whereas, the cascade passive single-basin single-slope solar system is the most appropriate design for domiciliary application.
