DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar cell module mounting structure in which a solar cell module having a solar cell is mounted on a roof.

[0002]

2. Description of the Related Art Conventionally, as a power generating element for converting solar energy into electric energy, a solar cell composed of a silicon semiconductor or the like has been widely used. When using this solar cell, generally, a rectangular flat-panel solar cell panel in which a predetermined number of solar cells are incorporated in a frame-like frame is used as a solar cell module, and this solar cell panel is used for a roof or the ground. It is juxtaposed with the part to be installed.

As a method for installing such a solar cell module, there is provided a mount having a right-angled triangular cross section on a flat surface such as a roof or the ground, and mounting the solar cell panel on the mount by inclining. A method in which a support rail is fixed on the roof base material of a sloping roof along the roof inclining direction, and a solar cell panel frame is mounted on this support rail to use the solar cell panel as a roof material (special method). No. 7-180310).

Further, the present applicant has formed a solar cell unit in which a solar cell panel is mounted on a frame having a triangular cross section, and a plurality of rails arranged in parallel on a flat grounded surface. There has been proposed an installation method for fixing an end of a solar cell unit between adjacent rails with a joint (see Japanese Patent Application No. 10-269593).

[0005]

However, according to the above method, the solar cell panel can be arranged in a state where the solar cell panel is viewed almost directly with respect to the sunlight that enters obliquely, so that the power generation efficiency of the solar cell is improved. Although you can,
Since the solar cell panel protrudes upward from the installation location (such as a building roof), a high wind pressure is applied to the solar cell panel. Therefore, reinforcement is required for the installation part on which the gantry is installed, and a stiffness member or a reinforcing material that can withstand the wind pressure is also required for the gantry, which complicates the work of installing the solar cell module. Work problems.

According to the above method, the roof base material requires special fittings for mounting rails and the like, and the type of roof to which such a solar cell module is mounted is a single-flow roof, a gable roof. However, since it is limited to a roof form such as a ridge roof, there is a problem in application that it cannot be installed in a building having a roof form such as a folded plate roof used in a home center or a warehouse.

Further, in the method (1), a plurality of solar cell units connected in the longitudinal direction are attached to the side-by-side rails by means of joints. A grounded surface is required. Therefore, in order to install such a solar cell module, for example, a leveled ground having a certain area or a flat grounded surface such as a flat roof is required. Moreover, for such a flat grounded surface,
In order to securely fix the solar cell module, fixing brackets and the like for fixing the rails are required, and in order to fix these fixing brackets to the grounded surface, it is also necessary to form mounting holes such as recesses on the grounded surface. Occurs. Therefore, there arises a problem that the operation of attaching the solar cell module becomes complicated.

An object of the present invention is to provide a mounting structure of a solar cell module which can be easily mounted and can be installed on a folded-plate roof.

[0009]

A solar cell module mounting structure 1 according to the present invention will be described with reference to the drawings. The solar cell module mounting structure 1 has a solar cell module 2 having solar cells mounted on a roof. And the roof is
A plurality of protrusions 61 are folded plate roofs 6 formed continuously in one direction K, and the solar cell module is provided so as to straddle the protrusions of the folded plate roof.

According to such a mounting structure for a solar cell module, the folded plate material used for the folded plate roof has grooves extending to allow rainwater to flow down and trapezoidal shapes projecting upward from these grooves. And a protrusion provided in a cross section. In a folded plate roof provided with a plurality of such folded plate members connected to each other, the height level of the protruding portion is usually set to be the same. Therefore, by arranging the solar cell module so as to straddle such protruding portions having a fixed height level, a pedestal such as a pedestal for fixing the solar cell module becomes unnecessary. It can be easily installed on a folded roof.

In the above, the solar cell module includes a module body 2 including a frame 21 having a polygonal cross section.
0, a joint 30 for connecting these module bodies to each other, and a rail 40 to which this joint is attached is preferable.

Normally, in the case of performing solar power generation, a plurality of solar cell modules are often used in combination instead of using only one solar cell module. Therefore, while providing a rail that is a long member along the projection of the folded plate, a plurality of module bodies are connected with a joint, and this joint is attached to the rail, so that the module body is stably placed on the folded plate roof Can be provided.

Further, the solar cell module includes a rail that separates the module body from the protruding portion of the folded plate roof. Therefore, by attaching the module body to the protruding portion via this rail, a space corresponding to the height of the rail is provided between the solar cell and the protruding portion. That is, there is no direct contact between the solar cell and the folded plate roof,
When the heat accumulated in the folded roof by the solar radiation is transmitted to the solar cell, it is transmitted through the rail. For this reason, for example, when the wind hits the rails, the rails storing heat may also be cooled, and the temperature rise of the solar cell itself is suppressed, so that the power generation efficiency of the solar cell can be improved.

Further, since a plurality of solar cell modules are connected by the joint, the electric energy (power generation amount) obtained by the solar cells can be increased, and the lighting, electric water heater, cooling and heating, etc. in the building can be increased. Power can be supplied to the equipment.

The rail is mounted on the protruding portion of the folded-plate roof along a direction in which the protruding portion extends, and a module body of the solar cell module is provided to intersect with a longitudinal direction of the rail. Preferably.

As described above, the rail is attached along the extending direction of the protruding portion of the folded-plate roof, and the lower end portion of the solar cell module is higher than the upper end portion of the protruding portion by the height of the rail. It is located only at a higher position. For this reason, a sufficient space is secured in the groove 62 of the folded-plate roof, and garbage such as fallen leaves falling into the groove of the folded-plate roof does not catch on the rails and falls in the inclination direction of the roof. Become. Therefore, it is possible to reduce the trouble of artificially sweeping out such dust and to reduce the work involved in the maintenance and management of the folded-plate roof.

Further, it is preferable that the rail is fixed to the protrusion by a bolt having a waterproof function.

Thus, the bolt having the waterproof function is
Since it is used when mounting the solar cell module on the protruding part of the folded plate roof, it is possible to prevent rainwater from entering the back of the folded plate through the bolt holes and prevent water from entering the solar cell module mounting structure. Performance can be improved.

Furthermore, it is preferable that a wiring storage space for storing wiring connected to the solar cell is provided inside the rail.

As described above, since the wiring storage space is formed in the rail, the wiring connected to the solar cell can be stored in the rail. Therefore, the wiring cannot be seen from the outside, and the external appearance of the mounting structure of the solar cell module can be improved. In addition, since the wiring is protected from direct irradiation with sunlight, it is possible to prevent, among the members constituting the wiring, a coating material that covers the conductive wire from being deteriorated by ultraviolet rays. Therefore, the usable period of the wiring can be extended,
Repair work on the mounting structure of the solar cell module can be reduced.

The solar cell module preferably has a triangular cross section.

As described above, among the side surfaces of the solar cell module having a triangular cross section, the solar cell is mounted on the side surface on which the sunlight S enters, and this side surface is used as the light receiving surface 21B, so that it is particularly in the middle latitude area. In Japan, solar cells can be placed in a state where the solar cells are viewed straight from sunlight that is incident obliquely throughout the year. Therefore, a large amount of solar energy is converted into electric energy by the solar cell, so that the conversion efficiency of the solar cell can be improved. In particular, a desired conversion efficiency can be obtained by setting the inclination angle of the light receiving surface of the solar cell module according to the solar radiation angle when the sun is at an altitude of the south and the middle.

Thus, the bolt hole of the protruding portion 61 is sealed, and the infiltration of rainwater is prevented.

Here, the mounting structure 1 of the solar cell module
The procedure for constructing is described below. 1. First, the solar cell panel 24 is assembled into the cylindrical frame 21 to form the module main body 20. 2. On the other hand, after forming the building body, on this building body,
The folded plate roof 6 is formed while a plurality of folded plates 60 are arranged. 3. Here, the folded plate roof 6 is formed, and
A plurality of rails 40 are arranged on one, and bolts 7 are inserted into the rails 40 from behind the projecting portions 61. 4. The module body 2 extends over a plurality of rails 40.
0 is arranged, the ends of the module main bodies 20 are connected to each other by a joint 30, and the joint 30 is fixed to the rail 40 by bolts 7 and nuts 8 to form a mounting structure of the solar cell module 2.

According to such a solar cell module mounting structure 1, the following effects can be obtained.
(1) The solar cell module 2 is provided on the folded plate roof 6 in which the protruding portions 61 are continuous in the gradient direction K so as to straddle the protruding portions 61 having the same height level along the ridge direction M. . For this reason, the solar cell module 2 can be easily installed continuously linearly in the ridge direction M without requiring a pedestal such as a pedestal.

(2) The solar cell module 2 includes a module main body 20 including a cylindrical frame 21 having a triangular cross section, and a joint 30 connecting the module main bodies 20 to each other.
And a rail 40 to which the joint 30 is attached. For this reason, while providing the rail 40 along the protruding part 61 of the folded plate 60, the plurality of module bodies 20 are connected by the joint 30, and the joint 30 is attached to the rail 40, so that the solar cell module 2 is stably provided. It can be provided on the folded roof 6.

(3) Since the rail 40 is disposed between the projecting portion 61 of the folded plate roof 6 and the module body 20, the heat accumulated in the folded plate 60 can be cooled by the rail 40. . For this reason, since heat is less likely to be transmitted to the solar cell panel 24, the power generation efficiency of the solar cell can be improved.

(4) Since the plurality of solar cell modules 2 are connected by the joint 30, the electric energy (power generation amount) obtained by the solar cell modules 2 can be increased, and the lighting, electric water heater, heating and cooling Electricity can be supplied to many facilities in a building.

(5) The rail 40 is mounted on the projection 61 along the direction (gradient direction) K in which the projection 61 of the folded-plate roof 6 extends.
It is provided crossing zero. For this reason, the rail 40 is provided in parallel with the direction in which the groove 62 of the folded plate 60 extends, and the module main body 20 is located at a position higher than the height level of the upper end of the protrusion 61 by the height dimension of the rail 40.
Is disposed. Therefore, trash such as fallen leaves falling into the groove 62 of the folded plate roof 6 does not catch on the rail 40 or the module body 20,
Since it falls in the gradient direction K of the roof 6, the trouble of artificially sweeping out such dust is reduced, and the work involved in the maintenance and management of the folded-plate roof 6 can be reduced.

(6) The rail 40 is a bolt 7 having a head 71 to which a packing material 71A made of hard rubber is attached.
Is fixed to the protrusion 61. For this reason, it is possible to prevent rainwater from entering the back surface of the folded plate 60 through the bolt holes 61A, and to improve the water resistance of the mounting structure 1 of the solar cell module.

(7) Inside the rail 40, a wiring storage space for storing wiring connected to the solar cell is provided. For this reason, the wiring becomes invisible from the outside, and the external design of the mounting structure 1 for the solar cell module can be improved.

(8) Since the wiring is accommodated in the wiring storage space, it is protected from direct irradiation of the sun rays S, so that, of the members constituting the wiring, the covering material for covering the conductor is made of ultraviolet rays. Deterioration can be prevented. Therefore, since the usable period of the wiring can be extended, the repair work of the solar cell module mounting structure 1 can be reduced.

(9) The module body 20 has a right-angled triangular cross-section, and the light receiving surface 21B provided with the solar cell panel 24 is substantially directly viewed from the sunlight S incident on the light receiving surface 21B. It is arranged in the state where it was done.
For this reason, much solar energy is converted into electric energy by the solar cell, so that the conversion efficiency of the solar cell can be improved. In particular, by setting the inclination angle of the light receiving surface of the module main body in accordance with the solar radiation angle when the sun is at an altitude of the middle and south, desirable conversion efficiency can be obtained.

(10) The module body 20 has a height of 31
The cylindrical frame 21 downsized to 5 mm is employed. For this reason, even if a strong wind blows on the roof 6, the wind pressure applied to the module body 20 can be suppressed lower than in a case where, for example, a flat solar cell panel is installed on a roof using a gantry. Therefore, when the solar cell module 2 is newly attached to the existing folded plate roof 6,
Compared with a flat solar cell panel, there is no need to provide a reinforcing member or the like, so that an increase in cost due to installation can be suppressed.

(11) The height of the module body 20 is 31
Since it is 5 mm, the shadow of the solar cell module 2 formed by the solar radiation is formed only on the inclined surface of the folded roof 6 facing south, and does not extend beyond the folded roof 6 to the northern boundary site. Therefore, especially in the winter season, no shade is created across the ridge, so that sunshine on the northern site can be secured.

(12) The cylindrical frame 21 is disassembled into a mounting sub-frame 23 for engaging the solar cell panel 24 and a supporting sub-frame 22 for supporting the mounting sub-frame 23. Since they are kept small, these subframes 22 and 23 can be easily handled.

(13) The mounting sub-frame 23 on which the solar cell panel 24 is disposed is provided with the engaging portions 23A,
23B is formed, and the upper and lower ends 24A, 24B of the solar cell panel 24 are passed through these engaging portions 23A, 23B,
The solar cell panel 24 is fixed to the mounting subframe 23. Therefore, since the solar cell panel 24 can be attached by a simple operation of inserting the solar cell panel, the installation work of the attachment structure 1 of the solar cell module can be facilitated.
