Researchers in Brazil have developed a hybrid tidal-PV floating farm concept for estuarine channels, analyzing wake effects, turbine spacing, and energy trade-offs. Integrating PV with hydrokinetic turbines improves energy yield by offsetting wake-related losses and optimizing farm configurations. The study focused on the Boqueirão Channel, with tidal ranges above 6m and current velocities exceeding 2.5m/s. Results show that greater turbine spacing allows for better wake recovery and higher energy yield, but creates a trade-off between energy yield and installed capacity. To address this, solar panels were installed on top of each turbine on a floating platform to maximize energy production. Simulation studies showed that increasing the number of columns in the farm layout resulted in higher energy generation and varying levelized costs of energy. The integration of photovoltaic generation helped compensate for energy losses from downstream turbines, improving overall productivity. The study concludes that hybrid systems are a technically feasible and economically promising solution for renewable energy deployment in estuarine channels.
