The purpose of this research work is to develop a water desalination unit that could efficiently produce potable water by evaporation and condensation; integrated with a Fresnel lens solar concentrator. The experimental setup consists of a heater tank powered with a Fresnel lens concentrator for pre-heating the water and a desalination unit. The objective of the work is to evaluate the enhancement in the performance of the system and was compared with the existing desalination unit. The study shows that Fresnel lens concentrator alone as pre-heating device can improve the yield of the desalination system up to 30.8 liters with an efficiency of 55%.
