According to the importance of economic solar ponds in domestic and industrial daily practical applications and its international widespread, this created the basis of an experimental study on a prismatic solar pond. It is internally painted in black with a surface measurement of (1m2) and a lower measurement of (0.42m2) and 1m deep. It constitutes four levels of gradual salinity separated by transparent glassy tablets /home glass/ of (6mm) thickness. On its lower level, a black solid mass is placed (black volcanic stones of equal dimensions; almost around 1cm). Upon studying the temperature and the stored thermal amounts of via subsidiary time every day from 9 am until 5 pm, the average rate of stored thermal amount each hour calculated according to the following equation: (Q = m.Cp.ΔT) during six months (February until July 2016) was: 9962.445 KJ, 9516.28 KJ, 10783.471 KJ, 9765.836 KJ, 14010.393 KJ, 12164.320 KJ respectively.
