Description

  The present invention relates to a solar cell module and a mounting structure thereof.

  For example, in Patent Document 1, instead of roof tiles or the like, solar cell modules are arranged over the entire roof, thatched roof is constructed, the installation area of the solar cell modules is increased, and solar power generation is efficiently performed. ing. Moreover, in patent document 2, in order to maintain the beauty | look of a roof, the solar cell module of a different dimension is combined and it has arranged in the whole roof.

  However, the techniques described in Patent Documents 1 and 2 are considered to be mainly applied to new houses, and in order to apply to existing houses, significant renovation work on the roof is required. It is difficult to apply.

  On the other hand, in order to spread solar power generation, it is important that it is easy to apply to existing houses as well as newly built houses. In addition, since it is necessary to renovate the roof due to deterioration over time, it is effective and desirable to simultaneously install the solar cell module and renovate the roof. For roof remodeling, a metal roof material that is lightweight and can be stacked is economically advantageous. For this reason, metal roof materials integrated with solar cell modules are sold by various companies.

For example, in Patent Document 3, a plurality of types of roofing materials are arranged and supported, and a plurality of types of solar cell modules having different sizes and standards are held by these roofing materials. Each roof material has a concave shape that can hold the solar cell module.

  However, since the metal roofing material integrated with the conventional solar cell module integrates the metal roofing material and the solar cell module using a dedicated member, an adhesive, a sealing member, etc., the metal roofing material It has a two-layer structure in which the solar cell module is overlaid on the top.

  Moreover, since a metal roofing material and a solar cell module differ in a manufacturing place, after moving at least one, both will be assembled and an effort and time are required.

  Furthermore, when not only a metal roof material in which solar cell modules are integrated on the roof but also a simple metal roof material, the solar cell module protrudes at least by the thickness of the roof. The beauty is impaired.

  In Patent Document 3, since the solar cell module is held in the concave shape of the roof material, the solar cell module does not protrude and the aesthetic appearance of the roof is not impaired. Etc. may accumulate, and there is a problem in durability.

  In addition, the construction of the metal roofing material integrated with the solar cell module is the same as the construction of the mere metal roofing material, but knowledge about the construction of the metal roofing material is required to install the solar cell module. It is. At the same time, since connection of the output terminals of the solar cell module and wiring processing are also required, the construction is not easy.

  Conventionally, since the roof material is directly fixed to the roof base plate, it is not easy to secure a wiring space in the inclined direction between the roof material and the base plate, and wiring processing is difficult.

  Therefore, the present invention has been made in view of the above-described conventional problems, and can be easily applied to a roof of an existing house as well as a roof of a newly built house, and can be easily manufactured and installed.

Moreover, since only the connecting member is fitted, the connecting member can be removed, and work such as repair and replacement of the solar cell module becomes easy.

  Furthermore, the mounting structure of the present invention includes a solar cell module main body, and a solar cell module mounting structure including a first frame body and a second frame body provided on two opposing sides of the solar cell module main body. The solar cell modules are arranged on the roof so that the first frame and the second frame are adjacent to each other, and the solar cell module is fixed on the roof in an upper portion of the first frame. A locking portion for locking the solar cell module on the roof is provided at a lower portion of the second frame body, and the first solar cell modules adjacent to each other are provided. The fixing portion of the frame body and the locking portion of the second frame body are fixed or locked on the roof by a common pressing member, and the lower portion of the fixing portion of the first frame body is adjacent to each other. Connecting part interposed between solar cell modules A first fitting portion for fitting the connecting member, and a second fitting portion for fitting the connecting member at a position above the locking portion of the second frame body, and adjacent to each other.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG.1 and FIG.2 is the perspective view and sectional drawing which show one Embodiment of the solar cell module of this invention. The solar cell module 10 of this embodiment has a solar cell module main body 10b in which a plurality of photovoltaic power generation cells 10a are arranged, and two long sides facing the solar cell module main body 10b are arranged on the first frame 11. The inner groove 11a and the inner groove 12a of the second frame body 12 are fitted to each other, and the long sides thereof are bordered by the first frame body 11 and the second frame body 12, and the two opposing solar cell module main bodies 10b are similarly opposed. The short sides are fitted into the inner groove (not shown) of the third frame 13 and the inner groove (not shown) of the fourth frame 14, and these short sides are fitted to the third frame 13 and the fourth frame. It is edged by the body 14. In addition, both ends of the first frame 11, one end of the third frame 13, and one end of the fourth frame 14 are engaged with each other, and both ends of the second frame 12, the other end of the third frame 13, and the first The other ends of the four frame bodies 14 are engaged with each other, and as shown in FIG. 3, the surfaces of the first to fourth frame bodies 11 to 14 are flush with each other to form a rectangular frame body. The solar cell module main body 10b is supported.

  On the upper surface of the first frame 11, a fixing groove 11b for fixing the solar cell module 10 on the roof is provided. A first fitting groove 11c that opens forward (in the direction of the eaves) is provided below the fixed groove 11b, and a protrusion 11d is provided at the edge of the first fitting groove 11c. Further, a leg portion 11 e is provided on the lowermost side of the first frame body 11.

  An L-shaped engagement portion 12b for locking the solar cell module 10 on the roof is provided on the lower side of the second frame body 12, and is locked to the forward protruding tip of the engagement portion 12b. A protrusion 12c is provided, and a downward projecting portion of the engaging portion 12b is a leg portion 12d. A second fitting groove 12e that opens forward is provided on the upper side of the engaging portion 12b, and a protrusion 12f is provided on the edge of the second fitting groove 12e.

  Next, a construction procedure for mounting the solar cell module 10 on the roof will be described with reference to perspective views of FIGS. 4 to 6 and side views of FIGS. 7 to 10. 7 to 10 show the construction state in which the existing color vest 15 is left on the roof, but the construction may be performed after the existing color vest 15 is removed. Even if the color vest 15 is left or removed, or the base plate of the roof of a newly built house is used as it is, the construction procedure does not change, and the members and tools used for the construction are not changed at all.

  First, as shown in FIGS. 4 and 7, a roofing 23 is laid on the entire color vest 15 of the roof or the field plate 21, and a plurality of vertical rails 22 are arranged on the roof along the inclination direction (vertical direction) of the roof. The vertical bars 22 are arranged and fixed at appropriate intervals. The vertical beam 22 is fixed using screws or nails.

  A plurality of hat steels 24 are arranged on each vertical rail 22 along a direction (lateral direction) orthogonal to the vertical rails 22, and each hat steel 24 corresponds to a substantially vertical width of the solar cell module 10. Fix the array with a gap. The hat steel 24 has a protruding portion 24a that protrudes upward in a U-shaped cross section, and fixed portions 24b on both sides of the protruding portion 24a. The hat steel 24 is fixed by passing a plurality of screws 25 through the fixing portions 24b and the vertical bars 22 on both sides of the hat steel 24 and screwing them into the field plate 21.

  Subsequently, as shown in FIG. 4, the waterproof member 26 is disposed at a joint position between the solar cell modules 10 arranged in the lateral direction, assuming the arrangement position of the solar cell modules 10. The waterproof member 26 has at least a length equal to or greater than the vertical width of the solar cell module 10 and is for receiving water leakage from a joint between the solar cell modules 10 arranged in the horizontal direction.

  Thereafter, as shown in FIGS. 4 and 8, a plurality of solar cell modules 10 are arranged between the hat steels 24. Since the plurality of hat steels 24 are arranged side by side, in any space between the hat steels 24, the plurality of solar cell modules 10 are arranged in a row in the horizontal direction without gaps. At this time, as shown in FIGS. 5 and 11, the vertically long T-shaped sealing member 27 is provided in the groove 13 a of the third frame 13 and the groove 14 a of the fourth frame 14 of each solar cell module 10 adjacent in the lateral direction. The solar cell modules 10 are sealed by being inserted. Thereby, it is possible to prevent water leakage from the joint between the solar cell modules 10 adjacent in the lateral direction, and rain leakage due to water leakage can be effectively prevented together with the waterproof member 26.

  The T-shaped seal member 27 can be pulled out from the groove 13a of the third frame body 13 and the groove 14a of the fourth frame body 14, and repair or replacement of the solar cell module 10 is facilitated.

  In addition, one hat steel 24 is shared between each of the solar cell modules 10 in the front row (the row closer to the eaves) and each of the solar cell modules 10 in the rear row, and the space between each row is narrowed to effectively use the space. The number of hat steels 24 is reduced.

  As shown in an enlarged view in FIG. 12, in the front row, the back surface of the first frame 11 of each solar cell module 10 is brought into contact with the side surface 24 c of the protruding portion 24 a of the hat steel 24, and The leg portions 11e of the first frame 11 are placed on the vertical bars 22, and the solar cell modules 10 are arranged in a row in the horizontal direction.

  In the rear row, the engaging portion 12b of the second frame 12 of each solar cell module 11 is placed on the upper surface 24d of the protruding portion 24a of the hat steel 24, and the engaging portion 12b is mounted on the side surface 24e of the protruding portion 24a. The solar cell modules 11 are arranged in a row in the horizontal direction.

  Here, focusing on one hat steel 24, the first frame 11 of the front row solar cell module 10 is placed on the hat steel 24, and the second frame 12 of the rear row solar cell module 10 is the hat steel 24. Since it is placed on the upper surface, a step corresponding to the height of the hat steel 24 occurs between the solar cell modules 10 in the front row and the solar cell modules 10 in the rear row. Thereby, the solar cell modules 10 in each row are arranged in a staircase pattern.

  Next, as shown in FIG. 4 and FIG. 9, each solar cell module 10 is fixed by using the presser fitting 28. As shown in FIG. 12, the presser fitting 28 has a C-shaped cross section, and one end 28a is fitted into the fixing groove 11b of the first frame 11 of the solar cell module 10 in the front row, and the other end 28b is in the rear row. In this state, the screw 29 is screwed into the protrusion 24d of the hat steel 24 through the hole in the center of the presser fitting 28. Thus, the first metal frame 11 of the front row solar cell module 10 and the second frame body 12 of the rear row solar cell module 10 are pressed and fixed by the presser fitting 28.

  As described above, there is a step corresponding to the height of the hat steel 24 between the solar cell module 10 in the front row and the solar cell module 10 in the rear row, so that the fixing groove 11b of the first frame 11 in the front row and the rear row The engaging portions 12b of the second frame body 12 have substantially the same height, so that the first frame body 11 in the front row and the second frame body 12 in the rear row can be fixed by one press fitting 28.

  Note that the second frame 12 of the solar cell module 10 in the foremost row is fixed by the dedicated presser fitting 28 without sharing the presser fitting 28 with other solar cell modules 10. Similarly, the first frame 11 of the solar cell module 10 in the last row is also fixed by the dedicated presser fitting 28 without sharing the presser fitting 28 with the other solar cell modules 10.

  After fixing each solar cell module 10 in this way, as shown in FIG. 4, FIG. 6 (enlarged view of portion A in FIG. 4), and FIG. 10, the first frame 11 of each solar cell module 10 adjacent in the vertical direction. Both the edges 31 a and 31 b of the connecting member 31 are fitted into the first fitting groove 11 c and the second fitting groove 12 e of the second frame 12, and the solar cell modules 10 are covered by the connecting member 31. Thereby, the water leakage from between the solar cell modules 10 adjacent in the vertical direction can be prevented.

  As shown in FIG. 12, the connecting member 31 has a substantially U-shaped cross section, and both edges 31 a and 31 b are bent inside the connecting member 31. The tip bent inside the one edge 31 a is firmly hooked on the protrusion 11 d of the first fitting groove 11 c of the first frame 11. The other edge 31b is bent inward to form a recess in the vicinity of the tip, and the protrusion 12f of the second fitting groove 12e of the second frame 12 is caught in this recess. Thereby, the connection member 31 is reliably supported between the solar cell modules 10 adjacent in the vertical direction.

  The connecting member 31 can be detached from the first frame body 11 and the second frame body 12, and repair and replacement of the solar cell module 10 are facilitated.

  Further, the connecting member 31 is set to a length different from that of the solar cell module 10. Thereby, the seam of each connecting member 31 in the horizontal direction and the seam of each solar cell module 10 are shifted to make it difficult for water leakage at the horizontal seam to occur.

  Further, the connecting member 31 is made of a thin metal or synthetic resin having a thickness of 0.3 to 0.5 mm. For this reason, in a state where the ends of the connecting members 31 adjacent to each other are overlapped, these connecting members 31 are connected to the first fitting groove 11c of the first frame 11 and the second fitting of the second frame 12. It is possible to make it fit in the joint groove 12e, and thereby more reliably prevent water leakage at the joint of each connecting member 31 in the lateral direction.

  Each solar cell module 10 is attached on the roof by the above construction procedure. What is necessary is just to perform the wiring process of each solar cell module 10 in the middle of construction. A space is formed between each solar cell module 10 and the base plate 21 by the leg portion 11e of the first frame body 11, the leg portion 12d of the second frame body 12, the vertical rail 22, and the hat steel 24. Thus, wiring of each solar cell module 10 can be easily performed.

  FIG. 13 illustrates the completed state of each solar cell module 10 mounted on the roof. Here, the solar cell modules 10 are arranged in the horizontal direction and the vertical direction on the roof, and the solar cell modules 10 are arranged on the stairs from the eaves 32 to the upward direction of the inclined surface of the roof. Further, a roof surface forming member 33 having substantially the same outer shape as the solar cell module 10 and the connecting member 31 is disposed in a space where the solar cell module 10 is not present.

  Similarly to the solar cell module 10, the roof surface forming member 33 is fixedly supported by the hat steel 24. And as shown in FIG. 14, the roof surface formation member 33 is attached so that the level | step difference of the roof surface formation member 33 and the frame of the solar cell module 10 may hardly arise. Thereby, the solar cell module 10 does not protrude on the roof, does not cause a sense of incongruity, and the entire roof has a unified appearance.

  Thus, in this embodiment, since the fixing groove 11b is provided on the upper surface of the first frame body 11 of the solar cell module 10 and the engaging portion 12b is provided on the lower side of the second frame body 12, the front row of solar cells If the first frame 11 of the battery module 10 is brought into contact with the side surface of the hat steel 24 and the second frame 12 of the solar cell module 10 in the rear row is placed on the hat steel 24, the fixing groove of the first frame 11 11b and the engaging portion 12b of the second frame body 12 have substantially the same height, and the first frame body 11 and the second frame body 12 can be pressed and fixed by the common press fitting 28.

  In addition, such a mounting structure creates a step between the solar cell modules 10, and the solar cell modules 10 are arranged in a staircase shape like a roof material such as a tile, so that each solar cell module 10 is particularly conspicuous. Even if no roofing material is used, the appearance of the roof is preferable.

  Furthermore, since the connecting member 31 is fitted into the first fitting groove 11c of the first frame 11 and the second fitting portion 12e of the second frame 12, each sun in the front row and the rear row is connected by the connecting member 31. Between the battery modules 10 is reliably sealed, waterproof performance equivalent to roofing materials such as tiles can be obtained, and the appearance is also preferable. Moreover, since only the connecting member 31 is fitted, the connecting member 31 can be removed, and work such as repair and replacement of the solar cell module 10 is facilitated.

  Further, since the T-shaped seal member 27 is inserted between the third frame body 13 and the fourth frame body 14 of each solar cell module 10 adjacent in the lateral direction, the T-shaped seal member 27 laterally extends. Adjacent solar cell modules 10 are reliably sealed, and waterproof performance equivalent to that of roofing materials such as tiles can be obtained. In addition, since only the T-shaped seal member 27 is inserted, the T-shaped seal member 27 can be removed, and work such as repair and replacement of the solar cell module 10 is facilitated. Furthermore, since the waterproof performance between the solar cell modules 10 is ensured by using the T-shaped seal member 27 together with the connecting member 31, the degree of freedom of arrangement of the solar cell modules 10 is increased.

  Further, the hat steel 24 can be used as a foothold for an operator on the roof, and helps prevent the operator from slipping. Moreover, since the hat steel 24 also serves as a reinforcement for the roof and the solar cell module 10, the durability of the roof and the solar cell module 10 against loads such as snow can be increased, and damage to the roof and the solar cell module 10 can be prevented. In addition, reinforcement of the frame of the solar cell module 10 becomes unnecessary, and the cost of the solar cell module 10 can be reduced. Further, the hat steel 24 can be made higher to increase the step of each solar cell module 10 arranged in a staircase shape, thereby increasing the appearance of the heavy feeling, and conversely, the hat steel 24 can be lowered. Further, if the solar cell module 10 is grounded through the hat steel 24 and the pressing member 28, the wiring can be simplified.

  Moreover, even if the existing color vest 15 is left or removed, or even if the base plate of the roof of a newly built house is used as it is, the construction procedure does not change and the members and tools used for the construction are not changed at all. Therefore, it is effective for the spread of photovoltaic power generation.

  Furthermore, since it is not necessary to combine the solar cell module with a roof member such as a tile, the manufacturing process is not complicated, and since the structure is simple, the entire structure can be made thin and the degree of freedom in design can be reduced. The appearance is preferable.

  In addition, this invention is not limited to the said embodiment, It can deform | transform variously. For example, the shapes and dimensions of the solar cell module frame, pressing member, hat steel, connecting member, T-shaped sealing member, and the like may be appropriately changed.
