Solar Still with Solar Tracking System: A Review

With solar energy as the source to power our plant; the solar still is the simplest desalination technology consisting of a shallow basin with a transparent cover and it is considered because of its cost, simplicity of design, operation and maintenance. It is equally very compatible for use in the world's poorest countries and adaptable, for it does not require complex technical know-how to operate and maintain. The efficiency of solar energy deployment and performance of a basin-type still is considered. The effect of solar tracking on the design and operating variables viz the ambient temperature, basin temperature, brine temperature, cover temperature, and solar radiation (irradiance/intensity) and how they influence productivity were examined and analyzed. Basin and brine temperatures have positive effects on the productivity, but the effect of glass cover temperature was not so obvious. It was clear from the results that the solar intensity impacted on the productivity positively. A sun tracking mechanism was explored to determine how this affects the performance of the still.
