DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar cell panel.

[0002]

2. Description of the Related Art In recent years, as an alternative to oil,
The use of inexhaustible and clean solar cells is attracting attention.
In order to obtain large electric power from this solar cell, for example, a solar cell panel is formed, a plurality of solar cell panels are juxtaposed, and the panels are connected to each other via a lead wire to take out generated electric power.

[0003]

In general, the light-receiving surface of a solar cell panel is constituted by arranging a large number of cells each having a size of about 10 cm in length and width. When a plurality of these solar cell panels are juxtaposed to form a solar cell power generation device, if the alignment between the panels is not strictly performed, the appearance seen from the light receiving surface side will be the mutual position of each cell of each panel Is displaced and becomes extremely unsightly.

[0004] In particular, when a plurality of solar cell panels are juxtaposed on a support frame or the like to form a wall surface of a building or the like, lead wiring for extracting power from the solar cells is performed from the back surface of the panel. Since the cells themselves were also arranged from the back side, it was not possible to consider the arrangement of the cells on the front side. Therefore, when the wall surface of the building by the solar cell power generation device completed by arranging a plurality of solar cell panels arranged from the back side is viewed from the front side, the mutual positions of the individual cells are shifted, which is extremely unsightly.

[0005] In view of the above circumstances, an object of the present invention is to provide a solar cell panel in which solar cells can be arranged side by side in an orderly manner.

[0006]

In order to solve the above-mentioned problems, a solar cell panel according to the present invention is a solar cell panel constituting a solar cell power generation device by arranging a plurality of solar cell panels in parallel, wherein at least the panel on the back surface is provided. The alignment mark is provided at a fixed position including a side orthogonal to the juxtaposition direction.

[0007]

According to the present invention, since the alignment can be performed side by side with the positioning mark, the external appearance from the surface of the solar cell power generation device having a plurality of solar cell panels juxtaposed becomes regular.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIGS. 1 and 2 are an external perspective view and a rear view, respectively, as viewed from a sunlight receiving surface of a solar cell power generation apparatus in which a plurality of solar cell panels of the present invention are juxtaposed. 1, 1,... Are solar cell panels that generate electricity by receiving sunlight, and each side of a single crystal, polycrystal, or amorphous is about 1
A large number of 0 cm single cells are arranged vertically and horizontally. The plurality of solar cell panels 1, 1, ... are provided side by side, and the generated power is taken out via a lead wire. Reference numerals 2 and 2 denote a pair of support frames arranged in parallel with the juxtaposition direction of the solar cell panels 1, 1,... As shown in the sectional view of FIG. Support from. Solar panel 1,
The support frames 2, 2 are fixed by seal members 3, 3. 4, 4,... Are alignment marks provided at fixed positions on the sides orthogonal to the panel juxtaposition direction on the back surface of the solar cell panels 1, 1,. Each is provided at the center position of two opposing sides. FIG. 5 is a perspective view of the solar cell power generation device as viewed from the back side, in which 5... Are terminal boxes.

In order to assemble the solar cell power generation apparatus, support frames 2 and 2 are provided in parallel, and a solar cell panel 1 is mounted on the support frames 2 and 2.
Slide 2 and place. Further, another solar cell panel 1 is similarly provided so as to be juxtaposed with the solar cell panel 1 arranged earlier. At this time, the alignment marks 4, 4,... Provided on the back surface of the solar cell panel 1 are aligned and fixed so as to align with each other. Further, the other solar cell panels 1 are similarly provided so as to be juxtaposed. At this time, the alignment marks 4, 4,... Are similarly aligned and fixed so as to align. By arranging a plurality of solar cell panels 1, 1,... Sequentially in the same manner in this manner, the solar cell panels 1, 1,. Can be aligned with each other.

The alignment marks are not limited to those shown in FIGS. 2, 4 and 5, but may be linear marks as shown in FIG. Further, as shown in FIG. 6, the alignment mark 4 may be provided at a fixed position including a side perpendicular to the panel juxtaposition direction and at a fixed position including a side parallel to the panel juxtaposition direction. Good.

According to this, when two or more rows of solar cell panels are provided side by side, it is possible to perform panel alignment (height adjustment) with respect to an adjacent row.

The alignment mark is not limited to a planar mark, but may be a three-dimensional mark. Furthermore,
When using a three-dimensional thing, form an engaging part in this,
By being configured to engage with the engaging portion formed on the similar three-dimensional alignment mark of the juxtaposed adjacent panel,
Once the alignment is performed, there will be no displacement afterwards due to wiring and other operations.

[0014]

As described above, according to the present invention, alignment marks are provided at fixed positions on the back surface of each solar cell panel at a side perpendicular to the panel juxtaposition direction. By aligning and juxtaposing the solar cell panels, the solar cell panels can be easily arranged in an orderly manner, so that each cell of the solar cell power generation device can be prevented from being displaced, and the appearance of the building can be particularly improved.
