Outdoor shading device with renewable power system

An outdoor shading device, comprising:

• a supporting frame which comprises a standing frame and an awning frame supported by said standing frame;
• a shading awning supported by said awning frame to define a shading area underneath said shading awning;
• and
• a solar power system as a renewable power system, which comprises:
• a renewable collecting unit comprising a solar collecting unit supported by said supporting frame for collecting energy from natural resources, wherein said solar collecting unit comprises a flexible solar layer having a solar collecting surface overlapped on said shading awning for solar energy collection, wherein when said shading awning is orientated for providing shade from the sun, said solar collecting surface of said solar collecting unit is aligned to face forward the sun to maximize the solar energy collection, such that after said solar energy is collected, said solar collecting unit converts said solar energy into electrical energy;
• a power storage supported at said supporting frame to electrically connect to said renewable collecting unit, wherein when said renewable collecting unit collects said energy, said energy is converted into electrical energy and stored in said power storage;
• and
• a reinforcing frame alignedly coupled with said awning frame to lock and retain said solar collecting surface of said solar collecting unit on said shading awning.
