DOUBLE-SHAFT SUN TRACKER BASED DOUBLE-FACED PHOTOVOLTAIC MODULE SYSTEM AND METHOD FOR INCREASING POWER GENERATION THEREOF

摘要

The present invention discloses a double-shaft sun tracker based double-faced photovoltaic module system, comprising: a double-faced photovoltaic module; front surface reflectors are arranged above two sides of the double-faced photovoltaic module; an edge of the inner side of the front surface reflector is overlapped with an edge of the outer side of the double-faced photovoltaic module; the front surface reflector is used for reflecting sun light to the front surface of the double-faced photovoltaic module; back surface reflectors are arranged at two sides below the double-faced photovoltaic module, respectively; the back surface reflectors are used for reflecting sun light to the back surface of the double-faced photovoltaic module; and the edge of the outer side of the front surface reflector and the edge of the inner side of the back surface reflector are disposed on the same vertical surface. According to the invention, the reflectors are arranged on the front surface and the back surface of the double-faced photovoltaic module; the size and the position of the reflectors are determined such that sun light irradiated on the reflector can be totally reflected to the double-faced photovoltaic module; the received luminous flux of the double-faced photovoltaic module is greatly increased, thereby achieving the purpose of sufficiently utilizing the double-faced photovoltaic module to increase the power generation of the double-faced photovoltaic module.
