EXPERIMENTAL AND THEORETICAL STUDY ON EFFICIENCY OF PORTABLE MINI SOLAR POND USING DISSIMILAR SALTS

Abstract

Solar energy was used from the ancient period itself. Solar energy can be entrapped by a number of ways but most prominent
way by using solar pond. Solar pond has four types this paper deals with non convective salinity gradient solar pond. Solar
thermal energy generated by a salinity gradient solar pond (SGSP) is one of the significant promising techniques for providing
heat for desalination and other applications. Most commonly used salt is sodium chloride, but in this research, table salt which is
having the similar properties like sodium chloride is used. A pond was located at 11°N walls were inclined at 45° to the
horizontal. The pond was built of mild steel (1.6 mm thick) with a trapezoid surface area and with total depth of 1.7 m2 and 500
mm. The pond was insulated by 20 mm, 2mm thick of thermo styrene and High Density Polyethylene sheet.
