A frame structure for solar cell module, comprising:
- four sidebars and four corner connectors in a manner that any two neighboring sidebars are connected by one corner connector selected from the four corner connectors, and is characterized in that each of the four sidebars is comprised of a bottom, a first vertical wall, a second vertical wall, a first horizontal wall and a second horizontal wall in a manner that the first vertical wall is formed with a width larger than that of the second vertical wall, and the first vertical wall is connected to an end of the bottom by an end thereof while being arranged perpendicular to the bottom;
- the second vertical wall is connected to the bottom and is arranged perpendicular to the bottom while allowing the second vertical wall to be spaced from the first vertical wall by a specific first distance;
- the second horizontal wall is connected to an end of the first vertical wall that is disposed away from the bottom while being arranged perpendicular to the first vertical wall;
- the first horizontal wall is perpendicularly connected to the first vertical wall and is spaced from the second horizontal wall by a specific second distance while being arranged abutting against an end of the second vertical wall that is disposed away from the bottom;
- the first horizontal wall is projectedly formed with a sixth curvature part at a side thereof that is arranged away from the first vertical wall and facing toward the second horizontal wall, and also is indentedly formed with a fifth curvature part at a side thereof that is arranged proximate to the first vertical wall and facing toward the second horizontal wall;
- the second horizontal wall is projected formed with a first curvature part at a side thereof that is arranged away from the first vertical wall and facing toward the first horizontal wall, and also is indented formed with a second curvature part at a side thereof that is arranged proximate to the first vertical wall and facing toward the first horizontal wall;
- the first vertical wall further is indentedly formed with a third curvature part at a side thereof that is disposed neighboring to the second horizontal wall and sandwiched between the first and the second horizontal walls, and also is formed with at least two fourth curvature parts that are projectedly formed and at least one fourth curvature part that is indentedly formed on the same side of the third curvature part;
- wherein, each of the at least two projectedly formed fourth curvature parts is formed with a curvature the same as that of each of the at least one indentedly formed fourth curvature part, while allowing each of the at least one indentedly formed fourth curvature part to be arranged at a position surrounding by the at least two projectedly formed fourth curvature parts;
- and further the second and the fifth curvature parts are arranged connecting respectively to the third curvature part and the at least two projectedly formed fourth curvature parts that are formed neighboring thereto on the first vertical wall.
