Some countries in Asia are actively promoting floating solar systems, but solar system no matter on land or on water are often damaged by strong wind like typhoons. Generally the solar panel or system on land are subjected to non-uniform wind pressure, and are influenced by wind speed (V), wind direction angle () and module tilt (). Similarly, except of the environmental factors (V, , ), the floating solar system on water is additionally affected by the wave effect such as wave direction angle () and wave period (T). This research studied the floating solar panels on water due to wind-wave effect by three steps. Firstly, survey both the hydrological and meteorological data within typhoon days from three offshore observatories (Longdong, Hsinchu and Qiqi) in Taiwan during 2013 to 2017, and analysis the worst condition like maximum wave height and wave period. Secondly, analyze single floating PV system sport behavior on water. Finally, use CFD simulation to get the wind-pressure coefficient (∆Cp) by the model of solar panel under the above worst conditions, and some extreme condition easily occurs when the wind and wave are in the same direction, lead to the solar panel is subjected to a more concentrated non-uniform pressure near the both edges. Results of this work have successfully delivered a database of Cp distribution on solar panel and transfer ∆Cp into 18 zones then averaging them as Mean Surface Pressure Pattern (MSPP@p1~p18), to fulfil the requirements of non-uniform mechanical loads test.
