Abstract

A solar cell module includes a plate-shaped solar panel including a plurality of solar cells arranged on same plane; a plate-shaped cell protection member that covers the plural solar cells that are arranged on the same plane; and a surface protection member that is bonded onto a top surface of the cell protection member; an outer frame that supports a circumference of the solar panel; and a brace having rigidity against bending and that supports a center area of a back surface of the solar panel in such a manner that both ends of the brace are joined to each of two opposed positions of the outer frame. An initial tension is provided to the brace.

Claims

1-4. -4. (canceled)

5. A solar cell module comprising:

a plate-shaped solar panel including a plurality of solar cells arranged on same plane;

a plate-shaped cell protection member that covers the plural solar cells that are arranged on the same plane; and

a surface protection member that is bonded onto a top surface of the cell protection member;

an outer frame that supports a circumference of the solar panel; and

a brace having rigidity against bending and that supports a center area of a back surface of the solar panel in such a manner that both ends of the brace are joined to each of two opposed positions of the outer frame, wherein

an initial tension is provided to the brace.

6. The solar cell module according to claim 5, further comprising a supporting member that is arranged on the brace and that supports a solar cell portion arranged on the center area on the back surface of the solar panel, wherein the supporting member includes a supporting plate that is formed in such a manner that a circumference of the supporting plate is arranged in a gap between the plural solar cells.

7. A solar cell module comprising:

a plate-shaped solar panel including a plurality of solar cells arranged on same plane;

a plate-shaped cell protection member that covers the plural solar cells that are arranged on the same plane;

a surface protection member that is bonded onto a top surface of the cell protection member; and

a back-surface plate that is bonded onto a back surface of the cell protection member; and

an outer frame that supports a circumference of the solar panel, wherein

a thickness t₂ of the back-surface plate is set to a value equal to or larger than a thickness t_A that is calculated by Equation (1) and equal to or smaller than a thickness t_B that is calculated by Equation (2);

8. The solar cell module according to claim 7, wherein

the back-surface plate is a sandwich-structured panel in which a core material is sandwiches between two coat plates, and

a thickness t₂ is set to a value that is calculated by Equation (3), and the modulus of elasticity E₂ of the sandwich-structured panel is set to a value that is calculated by Equation (4):
