<br/><br/> The present work will be divided into two main parts numerical study and experimental work these two parts will cover the modeling & sizing of Solar MED main components which include MED 6 effects unit, steam generator and three ejectors. The three ejectors are used to create the required vacuum within the MED unit. Second point for the numerical part is CFD simulation for the flow inside the three ejectors, the simulation is carried on (ANSYS Fluent 18.2). The experimental part starts with manufacturing of Solar MED main components, then installation of Solar MED plant and finally evaluation of the Solar MED plant thermal performance. Performance ratio and recovery ratio is used to evaluate the thermal performance of  the operating Solar MED plant, The system has variation of performance ratio from 1.5 and up to 4.3, while the achieved recovery ratio is (33.7  47)%
