FIG. 9 is a diagram illustrating an example of a fixing method between the base frame and the long side frame. FIG. 10 is a diagram illustrating another example of the fixing method of the base frame and the long side frame. The X direction in FIG. 1 is the row direction (first direction), and the Y direction orthogonal to the row direction is the column direction (second direction).

  As shown in FIG. 1, the solar cell module 1 includes a rectangular solar cell panel 2 and a frame 3 that surrounds a peripheral portion thereof. The detailed structure of the solar cell module 1 is not particularly limited. The frame body 3 is a frame member that surrounds the solar cell panel 2 and holds the solar cell panel 2. The frame 3 includes a long side frame (first frame, a frame extending along the column direction) 31 provided along the long side of the solar cell panel 2 and a short side frame provided along the short side. A body (second frame, frame extending along the row direction) 32 is provided. The frame 3 is provided with flat portions on the upper surface and the bottom surface.

  In the present embodiment, an example is shown in which the solar cell modules 1 are mounted in 2 rows × 3 columns. In FIG. 1, the long sides of the solar cell modules 1 are arranged so as to be parallel to the column direction. Moreover, the short sides of the solar cell module 1 are arranged facing each other.

  As shown in FIG. 2, four solar cell modules 1 adjacent to each other in the row direction and the column direction are connected by one side connecting member 5. More specifically, each of the long side frame bodies 31 is connected to the both side connecting members 5 at the places where the corner portions 4 of the four solar cell modules 1 adjacent in the row direction and the column direction are butted in a cross shape. Fixed. In the following description, a structure in which a plurality of solar cell modules 1 are connected by the both side connection members 5 is referred to as a connection body 7.

  In the corner portion 4 of the solar cell module 1 that forms the right side 7c and the left side 7d of the connection body 7, the corner portions 4 of the two adjacent solar cell modules 1 are in contact with each other (the corner portion 4 has a T shape). Each long-side frame 31 is fixed to one single-side connection member 6 at a location where they are abutted. Thereby, the connection structure of the connection body 7 is strengthened. In the first embodiment, the connecting member 5 is not installed at the corner 4 of the solar cell module 1 that forms the uppermost side 7a and the lowermost side 7b of the connector 7. Therefore, the solar cell modules 1 are not connected to each other at the corner 4 of the solar cell module 1 that forms the uppermost side 7a and the lowermost side 7b of the connection body 7.

  The connecting body 7 is supported by a base frame 8 extending in the row direction. As shown in FIG. 3, the base frame 8 is a member that constitutes a base installed on a base 9 or a base (not shown), and directly supports the solar cell module 1. The foundation 9 is, for example, a pile or a section steel buried in the ground or a concrete base installed on the ground. The base is, for example, a frame material or a base on a base excluding the base frame 8.

  In the first embodiment, the connecting body 7 is supported by the two base frames 8 extending in the row direction. The base frame 8 has a U-shaped cross section. In addition, if the cross-sectional shape of the base frame 8 is a shape which can be fixed to the solar cell module 1 and the foundation 9, it will not be restricted to U shape.

  According to this mounting structure, two long side frames 31 are directly supported by one base frame 8 in one solar cell module 1. In the first embodiment, the solar cell modules 1 arranged in the same row are illustrated as being supported by the same base frame 8, but the base frame 8 may be divided in the middle.

  FIG. 4 is a cross-sectional view of a portion where the solar cell module 1 is connected by the both-side connection member 5. The long-side frame 31 of the solar cell module 1 has a groove-shaped cross-sectional shape that opens to the inside of the frame to which the solar cell panel 2 is attached, and includes a side wall 3a and a side wall 3a that surround the solar cell panel 2. In order to sandwich the solar cell panel 2 between the upper surface portion 3b, the lower surface portion 3c, and the upper surface portion 3b that project from the upper edge and the lower edge to the inside of the frame, respectively, an intermediate surface portion 3d that protrudes from the side wall portion 3a is provided. In addition, since the short side frame 32 is also the same structure as the long side frame 31, the detailed description is abbreviate | omitted.

  The both-side connecting member 5 includes an upper bottom portion 5a, a lower bottom portion 5b, and a column portion 5c that connects the two portions. A groove facing the solar cell module 1 side is formed by the upper bottom portion 5a, the lower bottom portion 5b, and the column portion 5c. The both-side connecting member 5 has an unequal I-shaped cross-sectional shape in which the width of the upper bottom portion 5a and the width of the lower bottom portion 5b are different. The upper bottom portion 5a and the lower bottom portion 5b of the both side connecting members 5 form a plane, and the upper surface portion 3b and the lower surface portion 3c of the frame 3 (31) are sandwiched by inserting the solar cell module 1 into the groove. Can be installed on. According to such an attachment structure, it can suppress that a clearance gap opens between the short sides which the solar cell module 1 opposes in a connection part by external forces, such as a strong wind.

  Furthermore, as shown in FIG. 4, an inclined surface that is continuous with the inclined portion 3 e of the upper surface portion 3 b of the long side frame 3 is formed on the upper bottom portion 5 a of the both-side connecting member 5. By setting the width A of the upper bottom portion 5a and the width B of the lower bottom portion 5b to B> A, the sunlight of the solar cell panel 2 is prevented from being blocked by the upper bottom portion 5a, and the rigidity of the both side connecting members 5 Can be secured.

  The distance between the outer surface of the upper surface portion 3b and the outer surface of the lower surface portion 3c of the frame 3 (31) is C, the inner surface of the upper bottom portion 5a and the inner surface of the lower bottom portion 5b. If the distance between and D is D, then dimension D ≧ dimension C. It is preferable to reduce the difference between the dimension D and the dimension C.

  The connection part of the solar cell module 1 which forms the right side 7c and the left side 7d of the connection body 7 is the one-side connecting member 6 having a U-shaped cross section shown in FIG. May be connected. The one-side connection member 6 includes an upper bottom portion 6a, a lower bottom portion 6b, and a side wall portion 6c that connects both portions, and sandwiches the upper surface portion 3b and the lower surface portion 3c of the frame 3 (31) from the outside of the solar cell module 1. Installed as follows.

  The fixing method of the frame 3 and the connection members 5 and 6 includes bolt fixing, screw fixing, fitting, adhesion, or a combination thereof. It is preferable that the connection members 5 and 6 are bolt-fixed or screw-fixed at least one place with the frame 3 of each solar cell module 1 to be connected. For example, when the long side frames 31 of the four solar cell modules 1 are connected by the both side connecting members 5 and bolted, the two side connecting members 51 are formed on both sides, as shown in FIG. 5 is provided.

  In this case, it is preferable that the hole 51 is provided at a position that is symmetrical with respect to the center position in the length direction (Y direction, column direction) of the both side connection members 5. In the case of bolt fixing, as shown in FIG. 7, it is preliminarily placed at a position where it overlaps with the lower surface portion 3c of the long side frame 31 and the lower bottom portion 5b of the both side connection members 5 when the both side connection members 5 are fitted. Holes 33 and 51 are formed, and the bolt 10 is inserted in a state where the holes 33 and 51 of both parts are aligned, and screwed using the nut 11.

  In the case of screw fixation, as shown in FIG. 8, the both side connection members 5 are fitted to the lower surface portion 3 c of the long side frame 31 and the lower bottom portion 5 b of the side connection members 5, as in the bolt fixation. A hole smaller than the outer diameter of the screw 12 may be provided in advance at the overlapping position. The screw 12 may be a tapping screw. Since the screw surface of the screw fixing portion is in contact with both the hole 33 of the lower surface portion 3c of the long side frame 31 and the hole 51 of the lower bottom portion 5b of the both-side connecting member 5, an electric ground connection can be substituted. It becomes possible.

  When there is an existing hole 33 in the lower surface portion 3c of the long side frame 31, a design change for the solar cell module 1 is not required by providing a hole 51 in the lower bottom portion 5b of the both side connection member 5 accordingly. It can be. Also in the case of the one-side connecting member 6, the bolt fixing and the screw fixing may be performed similarly to the both-side connecting member 5.

  With such connecting members 5 and 6, the long side frame 31 is connected and connected at a location where the corner 4 of the solar cell module 1 is abutted in a cross shape or a location where it is abutted in a T shape. The body 7 can be formed. Moreover, although it is preferable that the short side frame bodies 32 of the adjacent solar cell module 1 are in contact, you may have a clearance gap.

  The connecting body 7 and the gantry of the solar cell module 1 are fixed by placing the lower surface portion 3c of the long side frame 31 on the upper surface portion 8a of the base frame 8 extending in the row direction. This is done by fixing the side frame 31. That is, the base frame 8 needs to be arranged at a position that does not overlap the both side connection members 5 in plan view. The short side frame 32 of the solar cell module 1 is not supported by the base frame 8.

  The base frame 8 is, for example, a shape steel, a roll-formed plate material, or an extruded shape, and has a cross-section of an equilateral L shape, a C shape, a U shape, a Z shape, or the like. FIG. 1 shows a base frame 8 that is above and a base frame 8 that is below the inclination of the solar cell module 1. Here, as shown in FIG. 9, the base frame 8 on the upper side aligns the holes 82 formed in the upper surface portion 8 a of the base frame 8 and the holes 34 of the lower surface portion 3 c of the long side frame 31. The bolt 13 can be inserted from the inside of the frame body, and the nut 14 can be screwed from below to be fastened.

  This is effective as a method of screwing the nut 14 from the lower side when it is easy to secure a work space on the lower side like the base frame 8 on the upper side. In addition, it is preferable that all the long side frame bodies 31 placed on the base frame 8 and the base frame 8 are fixed with bolts.

  On the other hand, with respect to the base frame 8 located below, the solar cell module 1 is fixed from above the long-side frame 31 using the presser fitting 15. The shape of the presser fitting 15 is not particularly limited as long as it can fix the solar cell module 1. For example, as shown in FIG. 10, the presser fitting 15 includes a lower surface portion 15a, a column portion 15b, and a hook portion 15c, and a hole 151 through which the bolt 16 passes is provided in the lower surface portion 15a.

  Bolts 16 are inserted from below into holes 83 formed in the upper surface portion 8a of the base frame 8, the bolts 16 are passed through holes 151 provided in the lower surface portion 15a of the presser fitting 15, and the hook portions 15c are solar cell modules. The presser fitting 15 is placed so as to overlap with the upper surface portion 3b of the long side frame 31 of one, and the nut 17 is screwed onto the bolt 16 from above via the lower surface portion 15a of the presser fitting 15, so that the solar cell module 1 is fixed.

  This is effective as a method of screwing the nut 17 from the upper side when it is difficult to secure a work space on the lower side like the base frame 8 below. In addition, it is preferable that all the long side frame bodies 31 placed on the base frame 8 and the base frame 8 are fixed with bolts.

  The hook portion 15c of the presser fitting 15 that holds the upper surface portion 3b of the frame body 3 forms an inclined surface that is continuous with the inclined portion 3e of the long side frame body 31 so that the sunlight incident on the solar cell panel 2 can be formed. Blocking can be suppressed. In the example of FIG. 1, the base frame 8 and the frame body 3 above the inclination are directly fixed by the bolts 13 and the base frame 8 below the inclination is fixed by the presser fitting 15. The fixing method may be adopted.

  In the configuration as described above, the connection members 5 and 6 are used as rigid members and are connected so as to sandwich the long-side frame 31 of the adjacent solar cell module 1. Thereby, the connection body 7 of the solar cell modules 1 in which all the solar cell modules 1 on one gantry are connected by the connection members 5 and 6 is formed.

  Returning to FIG. 1, the interval P between the base frames 8 that support the connecting body 7 is P ≧ with respect to the side length Lm of the solar cell module 1 in the direction orthogonal to the base frame 8 (Y direction, column direction). The length Lr of the connection members 5 and 6 is Lr <Lm, and the length Q of the lowermost side 7b of the connecting body 7 from the base frame 8 below the inclination is Q ≦ 0.8 × Lm. For example, if the side length Lm in the row direction of the solar cell module 1 is about 1600 mm, the interval P between the base frames 8 is 2000 to 2500 mm, the connecting member length Lr is 600 to 1200 mm, and the base frame 8 to the lowermost side of the coupling body 7 The length Q of 7b is preferably 100 to 1000 mm.

  According to such a structure, since all the solar cell modules 1 on the gantry are connected to each other by the connecting members 5 and 6, the connecting body 7 is formed. Can receive a load. Therefore, deformation of the solar cell module 1 can be suppressed. Moreover, it is not necessary to use the frame material (frame material which fixes the short side frame 32) which supports the frame 3 of the solar cell module 1 in the column direction. Therefore, it is possible to reduce the number of frame materials used for the gantry. Further, since one solar cell module 1 is supported by one base frame 8, it is possible to further reduce the number of frame materials. As a result, a simple and cost-effective solar cell module mounting structure can be realized.

  FIG. 11 is a diagram illustrating an example in which the solar cell modules 1 are arranged in 3 rows × 4 columns in the mounting structure according to the first embodiment. Although FIG. 1 illustrates the mounting state in which the solar cell modules 1 are arranged in 2 rows × 3 columns, in FIG. 11, the solar cell modules 1 are arranged in 3 rows × 4 columns. As in FIG. 1, all the solar cell modules 1 are connected by connecting members 5 and 6, and in one solar cell module 1, two long side frames 31 are formed by one base frame 8. Supported.

  In the present invention, as long as two or more solar cell modules 1 are arranged in the row direction and the column direction, the number of installations is not particularly limited, and the connection body 7 of the solar cell modules 1 is configured with a simple and cost-effective structure. Can be configured.

  FIG. 12 is a diagram showing an example in which the short sides of the solar cell modules 1 are arranged so as to be parallel to the column direction. In this case, the connection body 7 of the solar cell module 1 is formed by connecting the short side frames 32 of the solar cell module 1 with the connection members 5 and 6. In addition, the base frame 8 extending in the row direction is fixed to the short side frame 32 to support the coupling body 7. 1, 11, and 12 are rotated 90 degrees in the row direction and the column direction, that is, the configuration does not change even if the X direction in FIG. 1 is attached as the column direction and the Y direction as the row direction.

  Examples of the materials for the connecting members 5 and 6 and the base frame 8 include iron-based materials such as carbon steel, high-tensile steel, rolled steel, stainless steel, and structural alloy steel, and plated steel using them as a base material, or Materials such as aluminum, magnesium, titanium, brass and copper may be used. In particular, by using aluminum, the weight can be reduced, so that workability is improved. Moreover, the durability with respect to corrosion, such as rust, improves by giving an oxide film and coating to the surface of aluminum. As shown in FIG. 6, by making the both-side connecting member 5 into a shape that can be produced by extrusion molding, it is possible to increase the thickness of the portion where rigidity is desired to be increased, to facilitate the addition of a rib or a hollow structure. be able to. The advantage of making it a shape that can be produced by extrusion is the same as in the case of the one-side connection member 6. Moreover, if it is extrusion molding, there also exists an advantage which can produce the elongate base frame 8 accurately.

Embodiment 2. FIG.
FIG. 13: is a perspective view which shows the attachment structure of the solar cell module 1 concerning Embodiment 2 of this invention. In addition, about the structure similar to the said embodiment, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

  In the first embodiment, the connection members 5 and 6 are not provided on the uppermost side 7a and the lowermost side 7b of the coupling body 7 of the solar cell module 1. However, in the second embodiment, the cross member except for the uppermost side 7a The long-side frame 31 is connected by the connecting members 5 and 6 at the corner 4 portion struck in a shape and the corner 4 portion struck in a T-shape.

  More specifically, at the place where the corner 4 of the solar cell module 1 is abutted in a cross shape, the solar cell module 1 is connected by both side connection members 5 similar to those in the first embodiment. In the corner portion that is abutted in a T shape like the lowermost side 7b of the coupling body 7 of the solar cell module 1, the length is less than half with the same cross-sectional shape as the both-side connecting member 5 used in the portion that is abutted in a cross shape. The two side connecting members 5 may be used. Of course, variations of the frame material may be reduced by using the same length.

  Although not shown in the drawings, the long side frame 31 may be connected by the both side connecting members 5 even at the corner 4 portion where the uppermost side 7 a of the connecting body 7 is attached in a T shape. According to such a configuration, the rigidity of the uppermost side 7a and the lowermost side 7b of the connection body 7 of the solar cell module 1 can be strengthened against an external force such as a strong wind. The configuration does not change even if the row direction and the column direction in FIG.

Embodiment 3 FIG.
FIG. 14: is a perspective view which shows the attachment structure of the solar cell module 1 concerning Embodiment 3 of this invention. FIG. 15 is a cross-sectional view of a portion where the solar cell module 1 is connected by both-side connection members. In addition, about the structure similar to the said embodiment, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

  In the first embodiment, the base frame 8 and the solar cell module 1 below the inclination are fixed using the presser fitting 15 (see also FIG. 10), and therefore, between the solar cell modules 1 arranged in the row direction, , A clearance is required for the presser fitting 15 to enter. Therefore, as shown in FIG. 4, the cross-sectional shape of the both-side connecting member 5 of the first embodiment is a hollow cross-sectional shape in which a gap is provided between the two column portions 5c that connect the upper bottom portion 5a and the lower bottom portion 5b. ing.

  On the other hand, in the third embodiment, as shown in FIG. 14, the fixing of the solar cell module 1 by the presser fitting 15 is eliminated, and all the fixing portions of the solar cell module 1 and the base frame 8 are as shown in FIG. Align the position of the hole 82 opened in the upper surface portion 8a of the base frame 8 and the hole 34 of the lower surface portion 3c of the long side frame body 31, and insert the bolt 13 from the long side frame body 31 side. 14 is screwed and fastened.

  Therefore, it becomes possible to narrow the space | interval of the solar cell modules 1 adjacent to a row direction rather than the attachment structure shown in Embodiment 1. FIG. Therefore, as shown in FIG. 15, the cross-sectional shape of the both-side connecting member 5 includes one column portion 5 c and sandwiches the upper surface portion 3 b and the lower surface portion 3 c of the long side frame 31 from the outside of the solar cell module 1. Connect as follows.

  Thereby, a mounting structure that can save space in the row direction is realized. The configuration does not change even if the row direction and the column direction in FIG.

Embodiment 4 FIG.
FIG. 16 is a cross-sectional view of a portion where the solar cell module 1 is connected by the both-side connection member 5 in the mounting structure of the solar cell module 1 according to the fourth embodiment of the present invention. FIG. 17 is a perspective view of the both-side connecting member 5. In addition, about the structure similar to the said embodiment, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

On the other hand, in Embodiment 4, the claw portion 5d is provided on the opening side of the lower bottom portion 5b of the both-side connecting member 5, and the upper surface portion 3b and the lower surface portion 3c of the long side frame 31 are sandwiched from the outside of the solar cell module 1. Install by fitting.

  When attached, the claw portions 5d of the both-side connecting members 5 are provided at positions closer to the end surface, inside the end surface on the inner side of the frame of the lower surface portion 3c of the long side frame 31. Moreover, as shown in FIG. 17, it does not interfere with the lower surface part 3c of the short side frame 32 of the solar cell module 1 near the center of the length direction (Y direction, column direction) of the both side connecting members 5. The claw portion 5d is not formed.

  When the width of the short side frame 32 is W, the width S of the portion where the claw portions 5d of the both side connecting members 5 are not formed is S ≧ W. Accordingly, when the both side connecting members 5 are moved in the length direction, the claw portions 5d of the both side connecting members 5 and the short side frame 32 interfere with each other, thereby preventing slipping. Since both side connection members 5 are attached by fitting, the distance between the outer surface of the upper surface portion 3b of the long side frame 31 and the outer surface of the lower surface portion 3c, and the inner side of the upper bottom portion 5a of the both side connection members 5 The difference in distance between the surface and the inner surface of the lower bottom 5b is made as small as possible.

  According to this configuration, the long-side frame 31 of the solar cell module 1 can be prevented from being detached from the both-side connecting member 5 by fitting, so that the bolts used for fixing the both-side connecting member 5 and the long-side frame 31 are fixed. The number of members can be reduced by omitting fastening parts such as.

Can be matched. Further, similarly to the two side connection members 5, the one side connection member 6 can be provided with a portion where the claw portion is not formed to prevent the one side connection member 6 from slipping.

Embodiment 5 FIG.
FIG. 18 is a perspective view of the both-side connection member 5 in the mounting structure according to the fifth embodiment of the present invention. In addition, about the structure similar to the said embodiment, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

  In Embodiments 1 and 2, when connecting the adjacent solar cell modules 1 with the both-side connecting members 5, the holes 51 formed in the lower bottom portions 5 b of the both-side connecting members 5 and the lower surface portion 3 c of the long-side frame 31 are used. The position of the provided hole 33 is aligned, the bolt 10 is inserted, and the nut 11 is screwed and fixed.

  In the fifth embodiment, the marking 52 is provided at the center position in the length direction (Y direction, row direction) of the both side connecting members 5 by a ruled line or engraving, and the upper side or the lower side of the solar cell module 1 is aligned with the marking 52 on both sides. A hole 51 is provided in advance in the lower bottom portion 5b of the both-side connection member 5 at a position overlapping the hole 33 of the lower surface portion 3c of the long side frame 31 when fitted to the connection member 5. The hole 51 in the lower bottom portion 5b of the both-side connection member 5 is provided at a central position in the length direction of the both-side connection member 5, that is, a position symmetrical to the marking position.

  Thereby, if one upper side or lower side of the solar cell modules 1 adjacent to each other in the column direction is fitted in accordance with the markings 52 of the both side connecting members 5, the lower surface portion 3 c of the long side frame 31 and the lower side connecting members 5 The positions of the bolt holes in the bottom 5b can be easily matched.

  Further, the short-side frame 32 of the other adjacent solar cell module 1 is fitted into the both-side connection member 5 with the side wall portion 3a facing and close to the short-side frame 32 of the solar cell module 1 described above. Thus, the long side frame 31 of the other solar cell module 1 can also be easily aligned with the both side connection members 5 and the bolt holes, so that the workability of assembling the solar cell module 1 to the both side connection members 5 is improved. Will improve. Moreover, since the marking 52 is not in an external appearance by attaching the marking 52 to a position excluding the upper surface of the upper bottom portion 5a of the both-side connecting member 5, the design property is not hindered.

  In addition, it is possible to improve the assembling workability by providing marking on the one-side connection member 6 similarly to the both-side connection member 5.
