The issue of water scarcity has been felt with more intensity in the arid and semi-arid regions. These regions are characterized by climate variability and recurrent droughts, affecting the socio-economic development of these areas. In remote areas with limited water resources, desalination is used as a primary source for drinking water supplies to communities. Between the various technologies available in desalination, inverse osmosis is the most used technology for drinking water production. Photovoltaic solar energy solves the issue of electrification in rural areas, becoming an added value since it allows achieve energetic autonomy for the conventional system. This paper aims to assess the potential of decentralized desalination using solar energy applied to small scale. To study the applicability and viability of the technology is realized pre-sizing of the reverse osmosis system associated with the photovoltaic system to be installed in a rural area in Cabo-Verde. The validation of this combination of technologies and their implementation at the site requires the guarantee of sustainable development for communities. The obtained results show the viability of drinking water autonomous production which ensures the needs of population.
