The utility model discloses a solar array piece of flexible encapsulation among solar energy UAV. Form for five layers of the surface encapsulation membrane that is mainly stacked in proper order by top -down, solar wafer, electrode line layer, epoxy resin glue layer, glass fiber cloth layer, electrode line layer is hugged closely and is formed integratively at the solar wafer lower surface, and the pressfitting is hugged closely at the solar cell panel back through epoxy glue to glass fiber cloth, and the surface encapsulation membrane pastes at the solar wafer upper surface. The utility model discloses can satisfy the comprehensive requirement of solar energy UAV in the aspect of battery conversion efficiency and unit area battery specific power two to can effectively solve effective combination problem of rigidity solar array and aircraft aerofoil curved surface, and can effectively reduce solar energy UAV in the loss of structural rearrangement measurement of quantities face, and then improve solar energy UAV's load -carrying ability.
