This thesis investigates the feasibility, design requirements and techno-economic performance of a coastal floating photovoltaic (FPV) system proposed along the western shores of North Stradbroke Island, in Moreton Bay region of Brisbane (East Queensland). The research responds to increasing interest in floating solar technologies as a solution to land use constraints, rising electricity demand and the transition toward low carbon, climate resilient energy systems in high irradiance regions such as Australia. The study first defines the global and national context of renewable energy and examines the environmental characteristics of South East Queensland. A particular focus is given to North Stradbroke Island, a site that combines favorable solar resources and relatively sheltered coastal waters with engineering challenges, including wave loading, wind stresses, corrosion risks and ecological sensitivity.
