Problems solved by technology

[0009] However, it is costly to process a hole in a hollow shape, and there is a possibility that water cannot be discharged at the end
In addition, if the frame section has the function of drainage, there is a problem that the strength design is restricted

Embodiment approach 1

[0021] figure 1 It is a plan view showing a schematic configuration of the solar cell module according to Embodiment 1 of the present invention. The solar cell module 1 has a solar cell panel 20 and a holding frame 50 for holding the solar cell module.

[0022] The light-receiving surface of the solar cell panel 20 has a substantially rectangular shape. Hereinafter, the long side of the rectangular shape is called the first side 20a, and the short side is called the second side 20b. The solar battery panel 20 is laminated in such a state that the solar battery cells connected in series are sandwiched by a sealing material, and glass and a back sheet are formed on both outer sides. A terminal BOX 30 for taking out generated electric power to the outside is attached to the back side of the light receiving surface.

[0023] The holding frame 50 is a frame-shaped member that surrounds the solar cell panel 20 and holds the solar cell panel 20 . The holding frame 50 has a main f...

Abstract

A holding frame includes a main frame member extending along a first side of the light-receiving surface, and a sub-frame member extending along a second side adjacent to the first side, wherein the main frame member includes a main outer wall extending along the first side, main holding units formed on the main outer wall to hold the solar cell panel from the first-side side, and a main bottom piece formed on the main outer wall protruding towards inside of the holding frame. The sub-frame member includes a sub-outer wall extending along the second side, sub-holding units formed on the sub-outer wall to hold the solar cell panel from the second-side side, and a cylindrical part formed to include the sub-outer wall, extending along the second side on the back surface side of the solar cell panel.

Description

technical field [0001] The present invention relates to a holding frame and a solar battery module, in particular to a drainage structure for the holding frame. Background technique [0002] A solar cell module is generally composed of a rectangular solar cell panel and a frame member (holding frame) for holding the solar cell panel. The solar cell panel is composed of a plurality of parallel solar cell cells. [0003] In recent years, in order to maintain strength, structures in which the frame cross-section is hollow are often used. When the cross section of the frame is hollow, water tends to accumulate inside the frame, and in cold regions, the water inside may freeze and expand to deform the frame. [0004] As its improvement, there are known a technique of providing drain holes in a hollow frame as in Patent Document 1, and a cross-section of a frame in which a path communicating with the outside is provided at an orthogonal frame joint portion as in Patent Document 2...
