Various proposals have been made to convert solar energy into electric power for use in solar cells. As a method of installing solar cells on the roof of a house or the like, a method of assembling solar cells into a panel to form a solar cell panel, and mounting the solar cell panel on a roof, and a method of mounting a solar cell on a roof material and installing a solar cell There is a method in which a roofing material with a battery is used as a roofing material with a battery and the roofing material with a solar cell is laid on a roof base material.

[0003] As for the former method of mounting a solar cell panel on a roof, there are a method of mounting a gantry on a roof and mounting the solar cell panel on the gantry, and a method of mounting a solar cell panel between roof materials. However, the method of mounting the solar panel on the roof via the gantry requires that the solar panel be firmly attached to withstand the wind pressure, making the installation work difficult and the solar panel to be installed on the roofing material. The method of installation in between takes a lot of man-hours to waterproof the seam between the roof and the solar panel, and in any case,
Both methods have the disadvantage of being expensive.

[0004] The latter roofing material with solar cells can be roofed on a roofing base material in substantially the same manner as conventional roofing materials such as tiles, which is extremely convenient. Examples of such a roof material with a solar cell include a roof tile with a solar cell described in JP-A-11-324234, and JP-A-11-324262.

[0007]

However, Japanese Patent Application Laid-Open No.
The roof panel with a solar cell described in Japanese Patent No. 324262 discloses that the solar cell is bonded to an aluminum plate with an adhesive, so that a force applied to the solar cell caused by a difference in thermal expansion and contraction between the aluminum plate and the solar cell is reduced. In addition, there is a problem that the solar cell may come off or fall off the aluminum plate due to the deterioration of the adhesive caused during use for many months.

[0008] The roof tile with a solar cell described in Japanese Patent Application Laid-Open No. 11-324234 merely secures the solar cell with claw members protruded on the surface of the solar cell. The force applied to the solar cell caused by the difference between the thermal expansion and contraction of the tile body and the solar cell is mitigated by the movement of the solar cell in the depression, and the above problem is not caused. When it is a metal plate such as a steel plate or a steel plate, a claw member is attached to the bank of the tile body with a fixing member such as a bolt, a screw or a rivet. Penetrate to the back of the tile body. As a result, there is a problem in that rainwater leaks from a gap formed around the penetrating fixing member onto the lower roof base plate.

[0009] Therefore, an object of the present invention is to provide a roof base material in which rainwater is provided even when a claw member for fixing the solar cell is attached to a thin metal plate to which the solar cell is attached with a fixing member such as a bolt, a screw or a rivet. To provide a roofing material with a solar cell which does not leak on the roof and a roofing structure in which the roofing material with a solar cell is laid on a roof base material of a sloped roof.

[0010]

A roof material body comprising a formed bank portion, a solar cell disposed in the concave portion, and a claw member for fastening the solar cell to the roof material body. And a fixing member for fixing the member, wherein the fixing member is provided in an overlapping area that is laid on an adjacently arranged roof material.

According to a second aspect of the present invention, in accordance with the first aspect, the claw member is provided on a bank portion above or below the water.

A third aspect of the present invention is the invention according to the first or second aspect, wherein a cushioning material is provided between the claw member and the surface of the solar cell.

According to a fourth aspect of the present invention, there is provided a roof base material having a sloped roof, wherein the roof material with a solar cell according to any one of the first to third aspects and a roof material disposed adjacent to the roof material with a solar cell are provided. And the roofing material arranged adjacent to the roofing material is roofed on an overlapping area of the roofing material with solar cells.

A fifth aspect of the present invention is directed to the fourth aspect of the present invention, wherein the roofing material with the solar cell according to the second aspect and the roofing material arranged adjacent to the roofing material with the solar cell are inclined roofs. A roofing structure that is laid on the roof base material of the above, the roofing material adjacent to the roofing material with solar cells, in a state of being stacked on the overlapping area of the roofing material with solar cells in the lower stage, It is a thing that is covered.

According to a sixth aspect of the present invention, in accordance with the fourth aspect, the roofing material with the solar cell according to the second aspect and the roofing material arranged adjacent to the roofing material with the solar cell are inclined roofs. A roofing structure that is laid on the roof base material of the above, wherein the roofing material with solar cells is laid in a state where an overlapping region is overlapped below the adjacent roofing material in the lower tier. .

The roof material body in the present invention includes a metal material, an inorganic material, a plastic material and a composite material thereof. A metal material is preferable from the viewpoint of weather resistance and the like, and a metal plate is particularly preferable because it can be formed on the roofing material main body by pressing it. Among various metal plates, stainless steel plate, galvanium steel plate, aluminum plated steel plate, galvanized steel plate, vinyl chloride coated steel plate, aluminum plate,
Aluminum alloy plates, copper plates and the like are preferred.

The roofing material body according to the present invention comprises a concave portion formed by recessing the central portion of the metal plate and a bank formed around the concave portion. In order to form the metal plate into such a shape, the metal plate may be formed by a press or the like, or the melted metal may be poured into a mold having the above shape and formed. The number of the concave portions may be arbitrary. For example, it may be one,
There may be more than one.

At this time, the concave portion is desirably shaped so that the solar cell can be completely fitted. Further, since the solar cell is provided with a terminal box, a lead wire, and the like, it is preferable to provide a recess for accommodating the terminal box and the lead wire in the concave portion. Further, since there is a cable for extracting electric power from the terminal box to the outside, a dent or a cutout for inserting the cable may be provided. The terminal box used at this time is usually a container made of a modified PPO (polyphenylene oxide) resin, and a lead wire having a cross-sectional area of approximately 2 mm ² is often used.

Further, when a bank portion on the water side of the roofing material body is extended in the water direction, and this extended portion is made higher than the bank portion to provide a water rim waterproof rib, rainwater falling on the roofing material body is reduced. Even if the upper surface of the roofing material with solar cells is back-flowed by wind or the like due to wind or the like, the water does not cross over the water-proof edge ribs, and as a result, rainwater does not leak onto the lower roofing material, which is preferable. In the present invention, one end of the claw member is attached to the bank above or below the roof of the roofing material body, but this is because one end of the claw member is attached only to the bank above the water. It may be attached to only the bank part below the water, or may be attached to both bank parts above and below the water. Furthermore, it may be attached to the left and right banks. The number of the claw members may be one or more. Further, there may be a plurality of claw members, and the claw members may be divided into two sets, one set being attached to the bank on the water side and the other set being attached to the bank section on the water side.

Although the material and shape of the claw member are not particularly limited, short members such as various types of plated steel plates and stainless steel are preferable. This short body depends on the shape of the solar cell and the bank,
It may be formed into an appropriate shape, for example, into a flat, curved, U-shaped, or Z-shaped shape. The other end of the claw member is inserted above the surface of the solar cell and pressed down from above to fix the solar cell. At this time, the other end of the claw member and the solar cell are fixed. It is preferable that a cushioning material is provided between the solar cell and the surface of the solar cell without damaging the solar cell.

As described above, as means for providing a cushioning material between the other end of the claw member and the surface of the solar cell, the cushioning material is previously attached to the lower surface of the other end of the claw member or the surface of the solar cell. The other end of the claw member may be extended over the surface of the solar cell, and a cushioning material may be provided between the other end of the claw member and the surface of the solar cell. When inserting the part on the surface of the solar cell to fasten the solar cell, sandwich the buffer between them, so as to provide a buffer between the other end of the claw member and the surface of the solar cell Is also good.

Although there are various types of such cushioning materials, a plate-like body of an elastic material such as silicone resin or rubber or a synthetic resin foam such as an acrylic resin foam is preferable. One end of the claw member is fixed by a fixing member penetrating from above the claw member to below the bank of the roofing material main body. Examples of such fixing members include rivets, screws, bolts and nuts.

The solar cell used in the present invention is not particularly limited. That is, there are solar cells made of semiconductors such as silicon-based semiconductors and compound semiconductors.Also, there are various types of solar cells such as single-crystal, polycrystalline, and amorphous silicon-based semiconductors and compound semiconductors. And so on. Although the size of the solar cell is not limited, it is preferable that the size of the solar cell be as large as possible within the concave portion of the roofing material body because the power generation amount of the solar cell increases.

It is preferable that the height of the solar cell is substantially the same as the depth of the concave portion, but it may be slightly higher or lower. For example, the height of the solar cell may be 1-5 mm higher or lower than the depth of the concave portion. If the height of the solar cell is different from the depth of the concave portion, the claw member attached to the bank above or below the water is a plate-like body having a step substantially equal to the difference, and this claw member is used. What is necessary is just to fix a solar cell.

The backing material used in the second aspect of the present invention reinforces the mechanical strength of the metal plate while adjusting the shape of the roofing material. That is, if the metal plate is thin,
It has the drawback that it is easy to bend and that people are likely to dent when placed on it. However, if a backup material is attached to the back surface of this metal plate, it will be difficult to bend and even if people are placed on it. This backup material may be provided with a notch or a recess through which a cable or the like passes as required.

If the backup material is heavy, the roof material with solar cells becomes heavy and the load on the roof increases,
Lighter is preferred. Also, those with excellent sound insulation and heat insulation properties make it difficult to hear the sound of rainwater falling on the roofing material with solar cells, making the living room under the roof quiet, and irradiating the sun with hot water. It is preferable because the thermal influence of the roof such as cooling at night in winter or the like is reduced.

As a backup material which is light and has high mechanical strength and is excellent in sound insulation and heat insulation,
Synthetic resin foams are preferred. As such a foam,
Polyethylene resin foam, polypropylene resin foam,
Styrene foam, acrylonitrile resin foam, PPO
Foams such as resin foam and PET (polyethylene terephthalate) resin foam can be given.

Although this backup material is attached to the back surface of the roofing material main body, any suitable attachment method may be used. For example, the backup material may be attached so as to wrap the backup material in the roof material body, the backup material may be bonded to the back surface of the roof material body with an adhesive, or may be bonded with a double-sided adhesive tape, a screw or the like. You may attach with a fixing member. In particular, if a backup material is adhered to the underside of the roof part of the roofing material water-tightly with the adhesive or double-sided adhesive tape, it will penetrate from the surface of the nail member to the backside of the roofing material body. Even if rainwater penetrates through the gap formed in the peripheral part of the fixing member, it cannot be further penetrated by the back-up material that is water-tightly adhered to the back of the bank, so that the rainwater can be No more leaking on the roof underlayment below.

The backup material has no problem if it has a heat-resistant temperature sufficient to withstand the use environment. However, if the heat-resistant temperature of the backup material is low, the space between the roof material body and the backup material is low. It is preferable to provide a heat-resistant heat-insulating sheet on the surface. As such a heat-resistant sheet, usually, a sheet having a heat resistance of 100 ° C. or more is desirable. A polyimide resin film can be given as such a heat-resistant sheet.

Further, it is preferable to provide a sound insulation sheet between the backup material and the roof material main body, because the sound insulation is improved and the sound such as a rain sound falling on the roof material main body is reduced. As such a sound insulation sheet, a polyethylene foam sheet is preferable. When the heat-resistant sheet and the sound insulation sheet are used together, a roof material having both functions is obtained. When the heat-resistant sheet and the sound insulation sheet are used in combination, it is preferable to stack the roof material main body, the heat-resistant heat insulation sheet, the sound insulation sheet, and the backup material in this order from above.
