It is well known that the usage of the distillate water increase day-by-day and large capacity can be produced by the principle of flashing system. Total money spend on the flashing system can be reduced by the solar thermal system compared to other thermal system. The main objective of the paper is to utilize the high temperature unit exit brine solution heat load to the low temperature flashing system and the heat load is reduced step by step. The low temperature the stages are designed up to the last level at which the brine solution heat load is not useful. At 120 °C of thermic fluid temperature the brine solution delivered heat load of 71.650 kW in the high temperature unit and 15.25 kW in the low/medium temperature unit respectively and it is used for the desalination process. The 1kg of mass flow rate of sea water produces 0.143 kg/s distilled water and low temperature unit produces additional distilled water of 0.032 kg/s. The production of distilled water is limited by thermic fluid temperature and brine solution concentrations.
