The United Nations Sustainable Development Goals (SDGs) and their interactions in developing countries in general, and in Egypt specifically, form the basis of our review. Issues of energy and water supply, linked to agriculture in rural areas, combine several of the SDGs. The current status and the challenges for solar photovoltaic (PV) electricity production and water supply technologies in rural areas are critically described and an outlook on future developments is provided. The framework of the water–energy–food nexus approach and its relation to the SDGs globally in the MENA region and in Egypt is presented and recommendations are given on institutional governance and research and development to overcome the silo mentality and enhance sector collaboration on all levels as prerequisite to achieving the SDGs. The latest technical developments in PV and water technologies and their opportunities for rural development are outlined. Combined technical solutions are highlighted with examples from Egypt. Specifically, installed systems in various rural locations are presented, and their advantages and shortcomings are discussed. The review provides a context for the studies presented in the Special Section on Solar Energy Solutions for Electricity and Water Supply in Rural Areas, Journal of Photonics for Energy, Volume 9, Issue 4.
