Photovoltaic-wind hybrid turbine system

摘要

There is provided a hybrid turbine system comprising a plurality of flexible and thin film photovoltaic modules or panels attached to a plurality of blades of a vertical-axis wind turbine (VAWT) for energy generation. Electrical performance of rotating photovoltaic modules or panels is enhanced since rotating photovoltaic modules are self-cooled by rotation of the blades of the wind turbine. It is experimentally shown that voltage of the photovoltaic modules decreases when the photovoltaic modules' temperature increases, and this decrease was modelled by four parameters namely ideality factor, reverse saturation current, short-circuit current, and material band gap. The present invention evidences that the proposed rotating photovoltaic modules increases the output voltage of the photovoltaic modules. Rotation of the photovoltaic modules as a part of the plurality of blades cools down and lowers the operating temperature of the photovoltaic modules and improves overall performance of the hybrid turbine system.
