Design of economical and effective solar ponds which are useful thermal energy storage devices, remains a huge challenge. The present work aims at investigating the thermal performance of low cost mini salt gradient solar pond. The portable pond was fabricated as a rectangular configuration having a volume of 0.5m3. Polystyrene and high density polyethylene sheets were employed for insulating the walls. The top of the pond was covered with a slender glass so that the dust accumulation could be prevented without affecting the absorption of solar radiation. Sodium chloride salt was used as the medium and the three salt gradient regions namely lower convective, non-convective, and upper convective regions were established through injection filling technique. The temperature and salt gradient data were observed experimentally for a period of 20 days at Coimbatore, India. The pond could absorb significant amount of available radiation (around 65%) and the maximum temperature of the pond was observed to be 49oC. Frequent washing of the water surface is necessary to maintain stable salt gradient. Nevertheless, portable pond fabricated with low cost materials exhibited good potential of storing solar energy for solar thermal applications.

“…Hence, the pond's thermal stability is increased, leading to improvement in the overall performance and efficiency of the solar pond. The common salts used in solar ponds are sodium chloride, magnesium chloride, or sodium nitrate, and their concentration in water ranges from 20 to 30 percent at the LCZ to virtually zero at the UCZ (Das & Ganguly, 2022). The stability of the pond is increased as the temperature rises from the UCZ to the LCZ.…”
