Abstract Floating photovoltaic (FPV) systems offer significant advantages over corresponding land-based ones. These include the ample surface available for arrangements in arrays, the possibility of exploiting the cooling effect of sea water on panel performance as well as the potential of integration of solar tracking techniques in a much more cost-effective way. However, application to coastal and offshore regions has proven to be a challenge, as FPV interaction with various environmental factors is not yet fully understood. In this work a twin hull floating platform is studied, featuring enhanced stability characteristics, in conjunction with lightweight structure, and quite efficient mobility. A novel Boundary Element Method developed for the hydrodynamic analysis of floating twin-hull structures is used for the calculation of responses in waves and its effect on the system power production. For the demonstration of the studied system, preliminary results - concerning the performance of a particular module in a selected coastal area of the Greek Seas - are presented and discussed. Finally, the effects of wave-induced dynamic motions on floating PV performance are presented, indicating significant variations of the performance index depending on the sea state.
