This aim of the study is to demonstrate the effect of a photovoltaic module installed on a small wind-photovoltaic hybrid generation system. Computational fluid dynamics(CFD) is used to interpret the velocity field around the photovoltaic module and the blade areas of a wind turbine. According to the simulation results, it is obvious that x_velocity and y_velocity varies very significantly with time near the photovoltaic module. This would lead to an increase of periodic wind load caused by flow separation at the edge of the photovoltaic module. This study discusses the flow characteristics in term of velocity and frequency analysis. Moreover we suggest a distance between a photovoltaic module and a wind turbine to avoid partially the negative effect caused by the photovoltaic module.
