Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a power generation roof tile having a solar cell for generating power.

[0002]

2. Description of the Related Art A power generation roof tile having a power generation function using a solar cell has been devised. The conventional method for constructing this type of power generation roof tile is to connect the roof tile body 2 of each power generation roof tile 1 as shown in FIG. By providing the terminals 3 and 4 and fitting the connecting terminals 3 and 4 of the adjacent power generation roof tiles 1 to each other, the power generation roof tiles 1 adjacent to each other vertically or horizontally are sequentially connected (for example, the actual public sho-63- 11747
No.).

[0003]

However, in the conventional case, a connection failure occurs due to the vibration of the power generation roof tile 1 and the warp of the roof substrate and the roof tile body 2, and in the case of the thin roof tile, there is a space for ensuring waterproofness and insulation. And thus the reliability of the connection
There was a problem of lack of (durability, insulation). In addition, the degree of freedom in connecting the power generation tile 1 is low, so
It is difficult to deal with the zigzag of 1 and it is necessary to combine a large number of roof tiles 1 in series and in parallel in order to obtain the required voltage, but such a connection cannot be accommodated. Furthermore, the roof shapes vary widely, and the arrangement of the power generation roof tiles 1 varies accordingly. However, it is difficult to connect in such a case, and it is difficult to connect the power generation roof tiles 1 in groups. This was not possible with the conventional method.

In view of the above problems, the present invention has been made to enable the wiring of the power generation roof tile to be made efficient and reliable, and to increase the degree of freedom of connection.

[0005]

[Means for Solving the Problems] The technical means of the present invention for solving this technical problem is to construct a power generation roof tile 7 having a solar cell 18 with a power generation function. The connection terminals 21 and 22 connected to both the positive and negative poles are provided, and the wiring 14 having the wiring terminals 12 and 13 for connecting the connection terminals 21 and 22 of the roof tile 7 is provided on the roof substrate in advance. Every other, the connecting terminal 2 of the roof tile 7
While connecting 1,22 to wiring terminals 12,13 of wiring 14,
The point is that I made that.

[0006]

[Function] When the power generation roof tile 7 is installed, it is sufficient to connect the connection terminals 21 and 22 of the power generation roof tile 7 to the wiring terminals 12 and 13 of the wiring 14 provided in advance, at the same time that the power generation roof tile 7 is being roofed. The tiles 7 can be connected efficiently and easily.

[0007]

The present invention will be described below with reference to the illustrated embodiments. As a model, as shown in Figure 3, projected dimensions 10m x 8m,
Gradient 4.5 / 10, staggered roof 6 of the ridge, width 910mm, working 182m
When the m roof tiles 7 are allocated, as shown in Fig. 4, 123 roof tiles 7 excluding the shaded area can be generated.

Power generation roof tile 7 1 output voltage is 1 power generation roof tile
It is determined by the number of cell stages in 7 and is designed in consideration of economy, but if it is assumed that DC 20V and DC 200V are required to convert to AC 100V, 10 cells are provided as shown in FIG. A total of 120 sheets of roof tiles 7 will be used by connecting them in series and connecting 12 groups of 10 sheets in parallel.

Next, when wiring the power generation roof 7,
As mentioned above, a certain rule is set to divide the power generation roof tile 7 in series and in parallel. FIG. 6 shows an example of a rule, which is sequentially connected from the left. It is to connect every other stage from top to bottom. More specifically, referring to FIG. 6, since the power generation roof tile 7A is the beginning and there is no bottom of the power generation roof tile 7A, it is shifted to the right and connected to the uppermost roof tile 7B. Connect the power generation roof tile 7B to the power generation roof tile 7C two steps below. Power generation roof tile
Since there is no bottom of 7C, move to the right again and connect to the top roof tile 7D. Hereafter, connect the power generation roof tiles 7E, 7F ... to the 10th power generation roof tile 7J. This is one group. The next group is
Connect in the same way from the power generation roof tile 7K under the power generation roof tile 7J (moving to the right and moving up).

FIG. 2 shows the connection of the power generation roof tile 7 divided as described above. In the figure, the circle indicates one end of the group, which is assumed to be the positive pole. ● indicates the connecting roof tiles 7, the double line and the broken line indicate the wiring route, of which the double line is the route pre-routed on the roof base, and the △ mark indicates the other end of the group, It becomes a negative pole. The X mark indicates a portion where the wiring of the wired double line is removed. The two-dot chain line and the three-dot chain line indicate parallel connection lines.
The above wiring rule makes it possible to prepare a standardized base material for wiring, a wiring cord, or the like, and has an effect that the roof base material can be made simpler and more reliable.

Next, a concrete example of the method of constructing the power generation roof 7 will be described. As shown in FIG. 1, a roofing 10 is pasted on a base plate 9, and a wiring crosspiece 11 is nailed on the roofing board 11 according to the allocation of the power generation roof tile 7. The wiring pier 11 is provided with wiring terminals 12 and 13 which are a pair of male and female waterproof connectors at intervals of twice the working width L of the power generation roof 7. Each pair of wiring terminals
Reference numerals 12 and 13 are provided at both ends of the wiring 14 and are electrically connected to each other. As shown in the figure, the wiring stiles 11 are aligned with the center line of the power generation roof tiles 7 and are attached at a 1/2 pitch of the working length W of the power generation roof tiles 7, and the positions of the wiring terminals 12 and 13 of the adjacent wiring stiles 11 are The working width L is offset in the roof flow direction. Between the wiring piers 11, piers 15 having the same height as the wiring piers 11 are nailed. Note that these piers 15 are the wiring piers in the example in the figure.
Although one is arranged in the middle of 11, the number can be appropriately set according to the bending strength of the power generation roof 7. It may also be a wide member.

In this way, the roof base is prepared, the wiring 14 having the wiring terminals 12 and 13 is provided in advance on the roof base, and then the wiring 14 is corrected according to the wiring pattern shown in FIG. That is, the preparation of the base is completed by removing the wiring 14 in the above-mentioned X portion and connecting the wiring in the broken line portion. Next, the power generation roof tile
That's seven. FIG. 1 shows three of a large number of power generation roof tiles 7. Each of the power generation roof tiles 7 is formed by sealing a solar cell 18 with resin on the back surface of the roof tile body 17. Both positive and negative electrodes (not shown) of the solar cell 18 are connected to the lead wires 19 and 20, and the other end of the lead wires 19 and 20 are connected to the connection terminals 21 and 22 which are waterproof connectors. Wiring the connection terminals 21 and 22
It can be detachably connected to 14 wiring terminals 12 and 13 by fitting. Then, first fix the power generation roof tile 7 on the lower stage to the splint 15 with screws 24, and connect the connection terminals 21, 22
Is connected to the wiring terminals 12 and 13 of the wiring 14. Next, the upper power-generating tiles 7 are zigzag-shaped and electrically connected in the same manner.
