Description

[Detailed Description of the Invention] This invention relates to a solar cell panel mounting structure in which the solar cell panel is attached and the electrical connection is made at the same time.

Solar cells are installed on the roofs, walls, etc. of structures such as lighthouses on uninhabited islands, and are widely used as a power source to cover part or all of the electricity used there.

By the way, an output cord is attached to a conventional solar cell in order to extract electrical energy obtained by converting light energy. Therefore, when installing such conventional solar cells on the walls of buildings, it is necessary to perform the installation work while connecting the output cord after wiring work, which is complicated and requires a lot of work. It took a lot of effort.

This idea was made in view of the above circumstances,
It is an object of the present invention to provide a solar cell panel mounting structure that is easy to install and allows electrical connection to be completed by attaching the solar cell panel.

This invention will be explained in detail below with reference to the drawings.

FIG. 1 shows an example of a solar cell panel used in the mounting structure of this invention, and reference numeral 1 in the figure indicates the solar cell panel. This solar panel 1
The solar cell 2 is provided on the front side.
This solar cell 2 has a cell 4 made of amorphous silicon or the like that converts light energy into electrical energy provided on the surface of a substrate 3 made of a smooth metal such as stainless steel or synthetic resin. A backing board 5 for reinforcement is bonded to the back side of the substrate 3, and its peripheral edge is bent toward the back side to form a box-like overall shape.
The above-mentioned backing board 5 has a thin upper portion in FIG. 1b so that it does not come into contact with the panel holder when the solar cell panel 1 is attached to the panel holder, which will be described later.

The bent portion of the peripheral edge of the substrate 3 is used as a side wall, and one longitudinal side wall 3a has an output contact 6,
6 is provided. This output contact 6,6
are male contacts, and are electrically connected to the positive or negative electrode of the solar cell 2, respectively. The output contacts are provided near both ends of the side wall 3a, and their protruding direction is directed toward the side wall 3b opposite to the side wall 3a.

Further, a long horizontal angle 7a is provided on the side wall 3b.
Further, vertical angles 7b, 7b having substantially the same dimensions as the width of the thick part of the backing board 5 are attached to the side walls 3c, 3c perpendicular to the side wall 3b.
It is attached closer to b.

FIG. 2 shows a panel receiver 8 to which the solar cell panel 1 of this example is attached. This panel support 8 is made of a material such as insulating synthetic resin, preferably reinforced plastic, and is formed into a long length, and a plurality of solar battery panels 1 are connected and locked to one panel support 8. It is becoming more and more common. The panel receiver 8 has a cross-sectional shape obtained by cutting a rectangular shape at a right angle. Connection contacts 9 are buried in the surface of the notch 8a facing upward in FIG. 2. As shown in FIG. This connection contact 9 is a female contact that fits with the output contact 6 of the solar panel 1, and the installation interval is determined from the installation interval of the solar battery panels 1, 1 and the interval of the output contacts 6, 6. It will be done.

These connection contacts 9... are connected to the panel receiver 8.
It is electrically connected by transmission wiring 10 provided inside. In this example, in order to connect the solar cells 2 in series when the solar cell panels 1... are installed, adjacent and different solar cells 1 are connected as shown by the two-dot chain line in FIG. The attached connection contacts 5, 5... are connected by a connection cord 10a.... In addition, the connection contacts 6, 6 at both ends of the panel receiver 8,
Output cord 10 led out to one end of panel receiver 8
b and 10b are connected to each other. Output code 1
0b, 10b, connection cords 10a, . . . are provided using wiring holes 11 formed in the length direction of the panel receiver 8. Furthermore, slits 12 are provided at predetermined intervals on the face wall of the panel receiver 8 to avoid the side walls 3c of the solar cell panels 1.

Next, a construction procedure for attaching the solar cell panel 1 to the wall surface of a building using such a panel receiver 8 will be explained.

First, as shown in FIG. 3, the rims 14 are attached to the pillars or walls of the building. These rims 1
4... are allocated and attached with dimensions approximately equal to the gap between the centers of the solar cell panels 1... to be attached later.

Next, the panel receivers 8 are attached to the furrows attached in the horizontal direction among these furrows 14. The installation of the panel receiver 8 is carried out with the notch 8a of the panel receiver 8 facing the front side, and the upper surface 8b in FIG. This is done with screws.

Next, the panel receiver 8 attached to the furring 14...
Attach solar panel 1 to ... sequentially. To attach the solar cell panel 1, first, its output contacts 6, 6 are fitted and locked into the connection contacts 9, 9 of the panel receiver 8. Thereby, the solar cell panels 1 are electrically connected to each other via the panel receivers 2. In this state, the horizontal angle 7a of the solar panel 1 overlaps with the next row of furring 14, and the vertical angle 7b of the solar panel 1 overlaps with the vertical angle 7b of the adjacent solar panel 1, as shown in FIG. 7b and the body rim 14, so
These angles 7a and 7b are fixed to the rim 14 with screws to ensure the installation of the solar panel 1.

After installing the solar panels 1... on the building in this way, in the gap between the panels 1, 1,
Push in the backup material 15 and sealing material 1.
6. Fill and seal.

In the solar cell mounting structure configured in this manner, the output contacts 6, 6 of the solar cell panel 1 are connected to the connection contacts 9 of the panel receivers 8 attached to the rim 14 serving as the base. By inserting the panels, the solar cells 2 are connected in series, and the panel 1 is attached to the wall 13 of the building. Therefore, the solar cells can be easily and quickly attached to the wall of a building, etc., compared to the conventional method of attaching the solar cells while connecting the wiring between the solar cells.

In addition, according to this mounting structure, the solar panel 1 can be mounted close to the pillars, walls, etc. of the building, so the solar panel 1 can play a role such as a wall building material forming the outer surface of the building. can also be used.

In addition, in the above explanation, the transmission wiring 10 in the panel receiver 8 was arranged so that the solar cells 2... were connected in series, but this transmission wiring 10 is
...may be connected in parallel.

As explained above, the solar cell mounting structure of this invention outputs the electromotive force of the solar cell and also serves as a means for locking the panel on the back side of the solar cell panel with solar cells on the front surface. A panel holder made of an insulating material is provided with contacts, has built-in transmission wiring, is connected to the transmission wiring, and is provided with connection contacts that fit with the output contacts, and is attached to a base such as a wall surface or a rim of a building; Since the output contacts of the solar cell panel are fitted and locked to the connection contacts of the panel holder, when the output contacts and the connection contacts are fitted and locked, the solar cells are electrically connected. , the solar battery panel is attached to the wall of a building via a panel holder. Therefore, according to the mounting structure of this invention, the solar cell panel can be easily and quickly installed on the outer surface of the building, and the solar cell panel can also function as a wall construction material.
