This book applies a plausible Multi-Criteria Decision-Making framework combining Analytic Hierarchy Process and Geographically Referenced Information to determine large-scale solar Offshore Floating Photovoltaic (OFPV) hot spots over Morocco's Mediterranean and Atlantic coastal areas. The book investigates the critical assessment criteria required as well as identifies moderately and very highly suitable areas. It highlights the resource and market potential, advantages, and challenges of various types of PV configurations, particularly OFPV systems. It also discusses the potential impact of climate variability and change on Morocco's offshore areas and hence on the suitability of OFPV, the benefits of marine energies, and the offshore potential of other renewable energy sources (offshore wind, tidal stream power, and ocean wave energy) along Moroccan coastlines, as well as the impact of climate change on these resources. The book also examines the challenges of water scarcity and discusses some solutions, such as PV-powered seawater desalination and the combination of OFPV with existing hydropower reservoirs in Africa.
