Abstract

PROBLEM TO BE SOLVED: To provide a roof provided with solar batteries, which is ensured with respect to the waterproofing performance and cooling function thereof, and to provide a method for setting solar battery panels. SOLUTION: This solar battery panels 50 are arranged along declining ridges 13 of the roof 10. One side of each solar battery panel 50 is arranged along the declining ridge 13, and a coping member 13A is set along the declining ridge 13 so as to caver one side. Thus, a joint portion formed between the solar battery panels 50, arranged along both sides of the declining ridge 13, is concealed by the coping member 13A, and therefore the joint portion is not exposed directly to rainwater. Furthermore, since the opening of a gap formed between the solar battery panel 50 and the substrate surface of the roof is blocked with the coping member 13A on the side of the declining ridge 13, infiltration of rainwater into the interior of the opening can be eliminated, thereby ensuring the waterproofing performance of the roof 10.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a large building extending horizontally, a descending building extending obliquely downward from an end of the large building, and a plurality of solar cell panels arranged along the downing building. And a method for installing a solar cell panel.

[0002]

2. Description of the Related Art Conventionally, a roof with solar cells that converts sunlight into electric power using a plurality of solar cell panels, which are roofing materials arranged vertically and horizontally on a roof surface, has been used. The solar cell panel is generally formed in a rectangular shape, and is fixed to a support member attached to the lower ground of the roof along the inclination direction of the roof surface (Japanese Patent Application Laid-Open No. 9-32206, etc.). reference). As a type of a roof with a solar cell, a roof according to a gabled roof in which solar cell panels are easily arranged along the inclination direction of the roof surface from the shape of the solar cell panel is generally used.
On the other hand, as a type of a roof with a solar cell, there is a case in which a roof is provided with a large building extending horizontally and a descending building extending diagonally downward from an end of the large building. When providing a solar cell panel on such a roof, if only rectangular solar cell panels are arranged on the roof surface, a large margin will be formed on the roof surface. Therefore, a plurality of irregularly shaped solar cell panels formed in a triangular or trapezoidal shape having a hypotenuse along the descending ridge are arranged on the roof surface along the descending ridge, and a plurality of rectangular solar cell panels are arranged vertically and horizontally on the remaining part. It is possible to arrange. At this time, if the roof surface angle between the descending ridge and the eaves and the plane angle between the oblique side and the bottom side of the irregular shaped solar panel are the same, the irregular shaped solar panel is When arranged along, the lateral sides extending along the inclination direction are parallel to the inclination direction of the roof surface, and the bottom sides are parallel to the eaves. Accordingly, the rectangular solar cell panels can be arranged on the remaining portion of the roof surface where the irregularly shaped solar cell panels are not arranged, and the solar cell panels can be arranged without gaps on the entire roof surface.

[0003]

However, triangular or trapezoidal solar cell panels are arranged along the descending ridge,
Edges on both sides of the roof panel of the solar cell panel extending along the inclined direction are supported by a pair of support members extending along the inclined direction. Thereby, a gap is formed between the solar cell panel and the lower ground of the roof, and outside air can flow through the gap to cool the solar cell panel. However, the opening of the gap on the down ridge side is exposed to the outside. However, it may be exposed to rainwater falling from the sky, and sufficient waterproof performance of the descending ridge may not be secured. In addition, if the opening on the descending ridge side of the gap formed between the solar cell panel and the lower ground of the roof is closed, waterproof performance of the descending ridge portion is ensured, but outside air does not flow through the gap. However, there is a problem that it becomes difficult to cool the solar cell panel.

An object of the present invention is to provide a roof with a solar cell and a method for installing a solar cell panel, which ensure the waterproof performance and the cooling performance of the roof.

[0005]

According to the first invention of the present invention, referring to the drawings, a large building 11 extending horizontally and a descending building 13 extending obliquely downward from an end of the large building 11 are described. And the roof 10 with solar cells, in which a plurality of solar cell panels 50 are arranged along the down ridge 13, each of the solar cell panels 50 has one side along the down ridge 13.
56 are arranged, and a coping member 13A covering one side 56 along the down ridge 13 is provided along the down ridge 13. Here, the solar cell panel 50 is
When arranging on the roof surfaces 14 and 15 of the roof 10 along, the solar cell panel 50 is supported, and a support member 40 provided on the roof surfaces 14 and 15 is employed. For example, roof surface 1
4 and 15 and the roof surface 1
A support member 40 protruding upward from 4, 15 is attached to the lower ground 18 of the roof, and both edges along the roof surfaces 14, 15 of the solar cell panel 50 are supported above the support member 40. I have. In addition, a coping member 13 provided along the descending ridge 13
A is formed to be hollow, and the upper end of the coping member 13A is connected to the main building coping member 11A for ventilation provided along the main building 11. With these, the solar panel 50 and the ground under the roof
A gap 17 is formed between the gap 17 and the gap 18,
A and the main building coping member 11A are communicated with each other, so that the outside air flows from the inside of the gap 17 to the coping member 13A and the main building coping member 11A, and the solar cell panel is heated by sunlight.
50 will be cooled. Then, the downside 13A side of the gap 17 is opened upward. In the first invention, since the joint formed between the solar cell panels 50 arranged on both sides of the descending ridge 13 is concealed by the coping member 13A,
The seams of the solar panel 50 are not directly exposed to rainwater that has fallen from the sky, and the solar panel 50 and the ground 18 under the roof are not exposed.
The opening on the side of the down ridge 13 of the gap 17 formed therebetween is closed by the coping member 13A, so that rainwater does not enter the inside of the opening. Thereby, the waterproof performance of the roof 10 and the cooling performance of cooling the solar cell panel 50 are ensured.

[0006] In the above, it is desirable that the solar cell panels 20, 50, 60 arranged along the descending ridge 13 are formed in a trapezoidal or triangular plate shape.
Thus, the hypotenuse 56 of the solar cell panel 50 and the roof surfaces 14, 15
When the plane angle α between the bottom 55 perpendicular to the inclination direction of the roof and the roof surface angle β between the descending ridge 13 and the eaves 12A, 12B is the same, the trapezoidal or triangular shaped solar cell panel 50
If the oblique side 56 of the solar cell panel 50 is arranged on the roof surfaces 14 and 15 along the descending ridge 13, the side edges 53 and 54 of the solar cell panel 50 extending along the inclination direction are parallel to the inclination directions of the roof surfaces 14 and 15. At the same time, the bottom 55 of the solar cell panel 50 is parallel to the eaves 12A and 12B. This allows the rectangular solar cell panels 30 to be arranged on the remaining portions of the roof surfaces 14 and 15 where the irregularly shaped solar cell panels 50 are not arranged. 30, 50 will be arranged. In addition, if the cap members 13A are provided along the descending ridge 13, the solar cell panels arranged on both sides of the descending ridge 13 can be provided.
As the seam formed between the 50 is covered by the coping member 13A, as described above, the solar cell panel 50
Seams are not directly exposed to rainwater and the solar panel 50
And the down ridge of the gap 17 formed between the ground 18 under the roof
Rainwater does not enter the interior of the roof 10 from the opening on the 13 side. Furthermore, by connecting the upper end of the hollow cap member 13A to the ventilation cap member 11A provided along the main building 11, outside air flows through the gap 17, and the solar cell panel 50 is cooled. As a result, waterproof performance and cooling performance of the entire roof 10 are ensured.

[0007] The solar cell panel 50 has a hypotenuse 56 extending along the descending ridge 13.
It is desirable that an overlapping area 4 overlapping with the coping member 13A is set along the oblique side 56 on the surface of 50. In such a roof 10 with solar cells, when the above-mentioned roof surface angle β is different from the plane angle α, the upper end of the hypotenuse 56 of the solar cell panel 50 arranged first is brought close to the descending ridge 13, and When the oblique sides 56 of the battery panel 50 are arranged so as to be linear, gaps 19A and 19B are formed along the descending ridge 13 between the descending ridge 13 and the oblique side 56 of the solar cell panel 50. For example, when the roof surface angle β1 is larger than the plane angle α, the width of the gap 19A between the descending ridge 13 and the hypotenuse 56 of the solar cell panel 50 increases from the eaves 12A and 12B to the large ridge 11, and The dimensions increase. On the other hand, when the roof surface angle β2 is smaller than the plane angle α, the width of the gap 19B between the descending ridge 13 and the hypotenuse 56 of the solar cell panel 50 increases from the large ridge 11 to the eaves 12A and 12B. The dimensions increase. Even if such gaps 19A, 19B are formed along the descending ridge 13, the width of the cap members 13B, 13C is reduced by the gap 19 described above.
If set according to the maximum width of A, 19B, the gaps 19A, 19B
Is covered with the coping members 13B and 13C, the gaps 19A and 19B are not exposed to the outside, the seam portion of the solar cell panel 50 along the descending ridge 13 is also covered, and the seam portion is not directly exposed to rainwater. In addition, the waterproof performance of the roof 10 is ensured, and the appearance of the roof 10 is not impaired.

Further, the solar cell panel 50 is provided with a plurality of solar cells 59A for converting sunlight into electric power,
It is desirable that these solar cells 59A are arranged outside the overlapping region 4. In this case, when the roof surface angle β and the plane angle α are different from each other, for example, the eaves 12A, 12B
Even if a gap 19B whose width increases from the main building 11 to the main building 11, the width of the overlapping area 4B of the solar cell panels 50 arranged along the downstream building 13 can be set as appropriate. The plurality of solar cells 59A provided inside the solar panel 50 along 13 are not covered by the coping members 13C, so that the sunlight received by the solar cells 59A is not blocked, and the power generation of the solar panel 50 is prevented. The quantity is not compromised.

The solar cell panel 50A is desirably formed in a trapezoidal shape. Here, when the trapezoidal solar cell panel 50A is divided into a triangular portion 50B including the hypotenuse 56 and a remaining quadrangular portion 50C, the overlapping area of the hypotenuse 56 of the solar cell panel 50 and the coping member 13A is considered. Even if a large 4D is secured, it is possible to set the overlapping area 4D mainly on the triangular portion 50B, and a large number of solar cells 59A serving as a light receiving surface are arranged vertically and horizontally on the quadrangular portion 50C without gaps. As a result, a sufficient light receiving area is secured in the solar cell panel 50A.

Further, the solar cell panel 50 is provided with dummy cells 59B and 59C in the vicinity of the hypotenuse 56, and an overlapping area 4 is set in the installation area of the dummy cells 59B and 59C so as to overlap with the coping member 13A. Is desirable. With this configuration, since the dummy cells 59B and 59C are provided near the hypotenuse 56 of the solar cell panel 50, it is not necessary to increase the width of the frame material along the hypotenuse 56 when setting the overlapping region 4. In addition, the overlapping area 4 between the oblique side 56 of the solar cell panel 50 and the coping member 13A is placed in the dummy cell 5
Since the solar cells 59A are set smaller than the installation areas of 9B and 59C, the solar cells 59A provided on the solar cell panel 50 are not covered, and the dummy cells 59B have the same appearance and texture as the entire frame material and the solar cells 59A. , 59C is now covered by the coping 13A, and the solar cell 59A
The frame material with different appearance texture is not exposed to the outside and the roof
The appearance of 10 is not impaired.

Further, solar cell arrays 70A, 70A including a plurality of solar cell panels 20, 50 arranged along the descending ridge 13 are provided.
0B and 70C have an edge along the said down ridge 13
, And is not parallel to the descending ridge 13, and is preferably covered by the coping members 13B, 13C, and 13D. In this way, the triangular or trapezoidal solar panels 20, 50 can be moved down

The oblique sides 25, 56 and the bottom sides 24, 55 of the solar cell panels 20, 50 are different from each other in the plane angle α.
Even if the edge of the solar cell array 70C formed by 0, 50 becomes zigzag, or becomes inclined at a different angle from the descending ridge 13, the edge of the solar cell array 70A, 70B, 70C is
Since the roof 10 is covered and covered with the cover members 13B, 13C, and 13D, the waterproof performance of the roof 10 is ensured, and the appearance of the roof 10 is not impaired. As a result, the number of roofs on which the solar panels 20 and 50 formed at a predetermined plane angle α can be installed increases, and the present invention is applied to various roofs 10 having different slopes of the roof surfaces 14 and 15 and the like. In forming the attached roof, an increase in the number of types of solar cell panels 20, 50 can be suppressed.

At this time, the solar cell arrays 70A, 70B, 70
C is one in which the edge along the descending ridge 13 is zigzag, or arranged at a different angle from the descending ridge 13 while the edge along the descending ridge 13 is arranged in a straight line. An inclined one can be adopted. Roof surface 14, 15

The width of the blank portion (gap 19A, 19B, 19C) formed between the edge of A, 70B, 70C and the descending ridge 13 is
Even if it is too large to cover with C and 13D,
If the solar cell array 70C having a zigzag edge along is used, the width of the margin (gap) is not expanded so large that it cannot be covered by the skirt member, and the skirt member 13 having an appropriate width is not expanded.
The space D (gap 19C) can be covered with D, the waterproof performance of the roof and the like are secured, and an increase in the types of the coping members 13D is suppressed.

On the other hand, when the width of the blank portion (gap 19A, 19B) formed between the edge of the solar cell arrays 70A, 70B and the down ridge 13 is not so large as to be covered by the cap members 13B, 13C. By adopting the solar cell arrays 70A and 70B whose straight edges are inclined at a different angle from the descending ridge 13, the edges of the solar array eaves 12A and 12B are also straight, In addition to making the appearance of the roof 10 good,

The width of the margin (gap 19C) formed between
The positions of the solar panels 20, 30, and 50 are determined based on the descending ridge 13 so that they do not become too large to be covered by 13D. After that, the solar panels 20, 30, and 50 are arranged. (Gap 19C) can be reliably covered with the capping material 13D, and the waterproof performance of the roof 10 is secured. In addition, even if the dimensions of the roof surfaces 14, 15 are different, the capping material 13D of a predetermined width can be adopted. Therefore, an increase in the types of the coping members 13D is suppressed.

In the above, after completing the arrangement of the solar cell panels 20, 30, and 50 along the descending ridge 13, a cap member 13D of the same width extending along the descending ridge 13 is installed.
It is desirable to cover the entire edge of the solar cell array 70C from below to above with the cap member 13D. By doing so, the headdress member 13D is arranged above the solar cell array 70C, so that the installation of the headdress member 13D can be easily performed, and the headdress member 13D allows the solar cell array 70C to descend.

According to the roof with solar cells and the method of installing the solar cell panels of the present invention, the following effects can be obtained. That is, according to the roof with the solar cell according to the first aspect, when the solar cell panels are arranged on the roof surface of the roof, the solar cell panels are supported by the support members provided on the ground under the roof. For example, a support member extending along the inclination direction of the roof surface and projecting upward from the roof surface is attached to the lower ground of the roof, and both sides along the roof surface of the solar cell panel are mounted above the support member. The edge is supported. In addition, a cap member provided along the down ridge is formed in a hollow shape, and the upper end of the cap member is connected to a ventilation cap member for ventilation provided along the main building. As a result, a gap is formed between the solar cell panel and the lower ground of the roof, and the gap, the coping member and the coping member for the main building communicate with each other. Circulates, and the solar cell panel heated by sunlight is cooled. The downward ridge side of the gap is opened upward. In the present invention, since the joints formed between the solar panels arranged on both sides of the descending ridge are concealed by the coping members, the joints of the solar panels are not directly exposed to rainwater falling from the sky. Since the opening on the down ridge side of the gap formed between the solar cell panel and the lower ground of the roof is closed by the coping member, rainwater does not enter the inside of the opening. Thereby, the waterproof performance of the roof and the cooling performance of cooling the solar cell panel can be secured.

According to the roof with the solar cell according to the second aspect, the plane angle formed by the oblique side of the solar cell panel and the bottom side orthogonal to the inclination direction of the roof surface is the roof surface angle formed by the descending ridge and the eaves. If it is the same as that, if the oblique side of the trapezoidal or triangular shaped solar cell panel is arranged on the roof surface along the descending ridge, the side edge of the solar cell panel extending along the inclination direction will be the roof surface. While being parallel to the inclination direction, the bottom of the solar cell panel is parallel to the eaves tip. This allows
A rectangular solar cell panel can be arranged on the remaining portion of the roof surface where the irregular solar cell panels are not arranged, and irregular and rectangular solar cell panels can be arranged on the entire roof surface without gaps. In addition, if the coping members are provided along the descending ridge, the joints formed between the solar cell panels arranged on both sides of the descending ridge will be covered by the coping members, as described above. The joint portion of the solar cell panel is not directly exposed to the rainwater, and the rainwater does not enter the inside of the roof from the opening on the descending ridge side of the gap formed between the solar cell panel and the lower ground of the roof. Furthermore, by connecting the upper end of the hollow-shaped cap member to the ventilation cap member provided along the main building, outside air flows in the gap, and the solar cell panel is cooled, The waterproof performance and cooling performance of the entire roof can be secured.

Further, according to the roof with the solar cell according to the third aspect, when the above-mentioned roof surface angle is different from the plane angle, the upper end of the oblique side of the solar cell panel arranged first is brought close to the descending ridge. When the oblique sides of the solar panels are arranged in a straight line, a gap is formed between the down ridge and the solar panel along the down ridge.
For example, when the roof surface angle is larger than the plane angle, the width dimension of the gap between the descending ridge and the oblique side of the solar cell panel increases as going from the eaves to the large building. On the other hand, when the roof surface angle is smaller than the plane angle, the width of the gap between the descending ridge and the oblique side of the solar cell panel becomes larger as going from the large wing to the eaves. Even if such a gap is formed along the descending ridge, if the width of the skirting member is set according to the maximum width of the gap, the gap is covered with the skirting member and the gap is exposed to the outside. The seams of the solar panels along the descending ridge are also covered, the seams are not directly exposed to rainwater, and the waterproof performance of the roof is ensured, and the appearance of the roof is not impaired.

According to the roof with solar cells according to the fourth aspect, since the dummy cells are provided near the hypotenuse of the solar cell panel, the width of the frame material along the hypotenuse is set when the overlapping area is set. You do not need to increase
Since the overlapping area between the oblique side of the solar cell panel and the coping member is set smaller than the dummy cell installation area,
The solar cell provided on the solar cell panel is not covered, and the entire frame material and a part of the dummy cell having the same visual texture as the solar cell are now covered with the coping member, so that the visual texture as the solar cell is obtained. However, the frame material different from the above is not exposed to the outside, and the appearance of the roof is not impaired.

Further, according to the roof with the solar cell according to the fifth aspect, when the trapezoidal solar cell panel is divided into a triangular portion including the hypotenuse and the remaining quadrangular portion, the solar cell panel is considered. Even if a large overlapping area between the hypotenuse and the coping member is secured, it is possible to mainly set the overlapping area in the triangular part, and a large number of solar cells serving as light receiving surfaces are arranged vertically and horizontally in the square part without gaps As a result, a sufficient light receiving area can be secured in the solar cell panel.

According to the roof with solar cells according to the sixth aspect, when the roof surface angle and the plane angle are different from each other, the width between the descending building and the solar cell panel increases from the eaves to the large building. It is possible to appropriately set the width of the overlapping area of each solar cell panel arranged along the descending ridge even if a gap in which the Of the solar cell is not covered with the shade member, the sunlight received by the solar cell is not blocked, and the power generation amount of the solar cell panel is not impaired.

Further, according to the roof with solar cells according to the seventh aspect, when arranging the triangular or trapezoidal solar cell panels along the descending ridge, the edge on the eaves side of the roof surface and the descending ridge. The angle between the roof surface and the plane angle between the hypotenuse and the bottom of the solar panel is different, and the edges of the solar cell array formed by these solar panels are zigzag, or at an angle different from that of the descending building. Even when the solar cell array is inclined, the edge of the solar cell array is covered and covered with a cover material, so that the waterproof performance of the roof is ensured and the appearance of the roof is not impaired. As a result, the number of roofs on which solar panels formed at a predetermined plane angle can be installed increases, and the present invention is applied to various roofs having different roof surface gradients and the like. An increase in the types of battery panels can be suppressed.

Further, according to the roof with solar cells according to the eighth aspect, when arranging the solar panels having a plane angle different from the roof surface angle of the roof surface, the edge of the solar cell array is made straight. Then, even if the width of the blank portion (gap) formed between the edge of the solar cell array and the descending ridge becomes so large that it cannot be covered by the coping members, the edge along the descending ridge becomes zigzag. If the solar cell array is adopted, the width of the blank portion (gap) is not expanded so large that it cannot be covered by the skirting member, and the margin portion (gap) can be covered by the skirting member having an appropriate width. The waterproof performance and the like are ensured, and an increase in the number of types of cap members can be suppressed.

Further, according to the roof with the solar cell according to the ninth aspect, the width of the blank portion (gap) formed between the edge of the solar cell array and the descending ridge is so large that it cannot be covered by the cap member. If it does not become larger, adopt a solar cell array in which the straight edge is inclined at a different angle from the descending ridge. Can be improved, and a margin (a gap) in which a solar cell panel cannot be installed can be suppressed to a minimum.

Further, according to the roof with solar cells according to the tenth aspect, when arranging the solar cell panels having a plane angle different from the roof surface angle β of the roof surface, the edge of the solar cell array and the descending ridge are arranged. Margins (gap) formed between
The installation position of the solar panels is determined based on the descending ridge so that the width of the solar panels does not become so large that they cannot be covered by the skirting members. After that, the arrangement of the solar panels is performed. Can be reliably covered with
The waterproof performance of the roof and the like are ensured, and even if the dimensions of the roof surface are different, since a cap member having a predetermined width can be adopted, an increase in the types of cap members can be suppressed.

Further, according to the roof with the solar battery according to the eleventh aspect, since the coping member is disposed above the solar cell array, the mounting work of the coping member can be easily performed. The capping material can ensure the waterproof performance of the edge portion along the down ridge of the solar cell array.
