In this era, one of the major problems facing many countries is water scarcity. Although global water availability is about 1.4 billion cubic kilometers and despite ongoing efforts to solve the problem, less than 3 percent of global water resources are drinkable. Moreover, freshwater availability is decreasing due to climate change causing droughts and continued population growth: it is estimated that global fresh water needs will increase by 20-30% within 2050. In this thesis, a system based on the direct coupling between a photovoltaic panel and a single-stage Direct-Contact Membrane Distillation (DCMD) system is proposed, which is suitable for mitigating the aforementioned issues, and thus able to produce electricity in a sustainable way and fresh water.
