摘要

Potential sites for floating photovoltaic (FPV) plants are identified in The Bahamas using a modified HydroLAKES database supplemented by satellite imagery and numerical wave model output. The results illustrate that across 38 inland waterbodies, creeks, and semi-enclosed coastal areas, there is a potential installed capacity and total photovoltaic power output of 3061 megawatts (MW) and ~ 6974 gigawatt hours (GWh) per year, respectively. This accounts for a tripling of the current potential installed capacity (~ 845 MW) and a quadrupling of electricity production (1930 GWh). It is possible to construct a 370 MW FPV array on a single lake within close proximity to major population centres. This array can provide an installed capacity larger than what would be required in 2030. For many waterbodies, the sizes, possible user conflicts, or status as protected areas limit their potentials for FPV arrays. FPV array migration into the nearshore can offset these disadvantages but comes at higher costs. Mild wave climates and shallow water allow for marine FPV arrays can increase power output even further. Electricity production can satisfy domestic energy needs and serve as an export product. Continued research into the socioeconomic and environmental effects of FPVs is highly encouraged to support renewable energy generation.
