Aluminum frame structure for packaging solar panel

An aluminum frame structure for packaging solar panel, in which a solar panel, being framed inside an aluminum frame structure, is substantially a lamination of glass covers and solar cell glasses that and packaged by a packaging material in a manner that the packaging material is to form a contact slop around the periphery of lamination of glass covers and solar cell glasses, and when ethylene vinyl acetate (EVA) and a back film is used as the filling material, the EVA is filled and sandwiched between glass covers and solar cell glasses while allowing the contact slope and the glass covers to be sealed by the back film;

• and, the aluminum frame structure comprises:
• a vertical support member;
• an U-shaped member, coupled to the vertical support member while allowing the opening of the U-shaped member to face toward a level direction;
• and
• at least one protruding member, disposed inside the U-shaped member, each having at least one protrusion arranged at the opening of the U-shaped member and at a position neighboring to the vertical support member while allowing the gap between the highest point of the at least one protrusion and an imaginary line representing the contact slope to be formed larger than the thickness of the back film, and also enabling the contact area of the at least one protrusion and the contact slope to be at least larger than 50% of the area of the contact slope.
