Hereinafter, an example of the embodiment will be described in detail with reference to the accompanying drawings. All of the drawings are schematically described, and the dimensional ratios of the components drawn in the drawings should be determined in consideration of the following explanations. It should be noted that the description of "abbreviated to" in the present specification is intended to include not only completely the same but also substantially the same when the substantially same is explained as an example.

1A and 1B are views showing a packaging form 11A of the solar cell module 10 which is an example of the embodiment, where FIG. 1A is a plan view, FIG. 1B is a sectional view taken along the line AA in FIG. It is a B arrow view in (a). The packaging form 11A is configured by stacking the solar cell modules 10 in a plurality of stages. The solar cell module 10 includes a solar cell panel 12 and a corner block 14.

The solar cell panel 12 is, for example, a plate-shaped member having a square shape in a plan view. The solar cell panel 12 has a structure in which a plurality of solar cell cells 2 are sandwiched between, for example, two resin sheets functioning as a sealing material and two protective members such as a glass substrate. In the present embodiment, an example is shown in which six rows of six solar cells 2 arranged in the horizontal direction are arranged in six rows in the vertical direction.

The corner block 14 covers and fixes the corners of the solar cell panel 12. The solar cell panel 12 of the present embodiment has a square shape and has four corners. Therefore, in the solar cell module 10, a total of four corner blocks 14 are fixed to each corner of the solar cell panel 12.

The solar cell module 10 further includes a terminal box 16 at one side edge of the solar cell panel 12. The terminal box 16 can be composed of, for example, a resin housing. The terminal box 16 contains an electrical connection terminal for collecting and outputting the electric power generated by the solar cell panel 12. As shown in FIG. 1A, the terminal box 16 is attached so as to project outward from the edge portion of the solar cell panel 12. Further, as shown in FIGS. 1 (b) and 1 (c), the terminal box 16 is attached so as to project from both side surfaces of the solar cell panel 12 in the plate thickness direction.

Cables 17 extend from both sides of the terminal box 16, and connectors 18 are connected to the ends of the cables 17. The cable 17 is a power line for taking out the electric power generated by the solar cell panel 12. Further, the connector 18 is an electrical connection member connected so as to electrically connect the solar cell modules 10 installed adjacent to each other.

In the solar cell module 10 of the present embodiment, the solar cell panel 12 is in a state where the edge portion is exposed except for the corner portion where the corner block 14 is fixed and the portion where the terminal box 16 is attached. There is. That is, for example, a metal frame is not fixed to the exposed edge of the solar cell panel 12. In this sense, the solar cell panel 12 can be said to be a frameless type solar cell module. However, in the solar cell panel 12, at least the edge portion other than the corner block 14 is covered with water ingress prevention means (for example, tape, coating film, etc., rubber packing covering the edge portion, a substantially U-shaped metal frame, etc.). ) May be provided.

As shown in FIG. 1B, each corner block 14 has a protrusion 20 formed on one side surface and a recess 22 formed on the other side surface. Therefore, when a plurality of solar cell modules 10 are stacked in a vertically stacked state to form the packing form 11A, the recess 20 of the solar cell module 10 in which the protrusion 20 of the solar cell module 10 located on the lower side is stacked on the upper side is formed. It can be fitted to 22 and stacked. As a result, a plurality of solar cell modules 10 can be stacked in a stable state. Further, when the solar cell module 10 is transported in this packing form 11A, it is prevented that each solar cell module 10 is displaced in the horizontal direction and collapses. As shown in FIG. 1 (c), on one side surface of the corner block 14 facing the outside of the solar cell module 10, a cable 17 for taking out the electric power generated by the solar cell panel 12 and a groove 24 into which the connector 18 is fitted are provided. It is recessed. The corner block 14 in which the protrusion 20, the recess 22 and the groove 24 are formed will be described in detail below with reference to FIG.

2A and 2B are views showing a corner block 14 as an example of an embodiment, where FIG. 2A is a top view, FIG. 2B is a front view, and FIG. 2C is a side view. The corner block 14 is formed of, for example, a resin material. However, the corner block 14 may be made of a metal member such as an aluminum die-cast molded product. In this example, the corner block 14 is integrally formed by one member.

As shown in FIG. 2, the corner block 14 is a plate-shaped member having a substantially square shape in a plan view. However, the corner block 14 may be formed in a shape in which the corners located on the solar cell panel 12 are obliquely cut off (triangular or pentagonal in plan view).

The corner block 14 has one side surface 14a and the other side surface 14b facing the thickness direction of the solar cell panel 12, and four side wall surfaces 15a, 15b, 15c, and 15d constituting the four sides. These four side wall surfaces 15a-15d become side surfaces along the thickness direction of the solar cell panel 12 when attached to the solar cell panel 12. Further, of the four side wall surfaces 15a-15d, the side wall surfaces 15a and 15b are side surfaces facing the outside of the solar cell module 10 when attached to the solar cell panel 12.

The corner block 14 is formed with a notch 26 into which the corner portion of the solar cell panel 12 is inserted. As shown in FIG. 2A, the cut portion 26 is formed as a recess having a shape corresponding to a corner portion of the solar cell panel 12 forming a substantially right angle. In the present embodiment, the cut portion 26 is formed in a substantially square shape in a plan view. Further, the cut portion 26 is open to the two side wall surfaces 15c and 15d of the corner block 14. The width W of the notch 26 is set to be slightly larger (for example, about several mm) than the thickness of the solar cell panel 12 in consideration of the space for arranging the adhesive or the like described later while allowing the solar cell panel 12 to be inserted. ing.

On one side surface 14a of the corner block 14, an L-shaped protrusion 20 (first protrusion) is formed in a plan view. On the other side surface 14b of the corner block 14, a recess 22 (second recess) forming an L shape in a plan view is formed. The recess 22 is formed wider than the protrusion 20. The protrusion 20 and the recess 22 are formed in a position and shape so as to fit each other when a plurality of solar cell modules 10 are stacked.

The positional relationship between the protrusion 20 and the recess 22 may be reversed. That is, a recess (first recess) may be formed on one side surface 14a of the corner block 14, and a protrusion (second protrusion) may be formed on the other surface 14b. Further, the shape and number of the protrusions and the concave portions are not limited to the L shape or one, and any shape and number can be used as long as the stacking position of the corner blocks is defined by the uneven fitting. Good.

The groove 24 for holding the cable 17 and the connector 18 is recessed in the corner block 14 on one side wall surface 15b facing the outside of the solar cell module 10 when attached to the solar cell panel 12. As shown in FIG. 2 (c), the groove 24 has a bottom surface formed as an arc-shaped curved surface. The width of the groove 24 is set so that the cable 17 and the connector 18 can be fitted and held. In the present embodiment, an example in which a groove 24 for holding a cable is formed on one side wall surface 15b of the corner block 14 has been described, but instead of or together with this, a cable holding groove 24 is formed on the other side wall surface 15a. Grooves may be formed.

3 (a) to 3 (c) are views showing stepwise how the two-divided corner block 14 is attached to the solar cell panel 12. As shown in FIG. 3A, the corner block 14 may be configured by combining the lower block 14c and the upper block 14d divided into two. The two-divided corner block 14 is fixed to the solar cell panel 12 as follows.

First, as shown in FIG. 3A, four lower blocks 14c are installed on the assembling table 28 corresponding to the four corners of the solar cell panel 12. A shallow recess 29 is formed on the upper surface of the assembling table 28 so that the lower portion of the lower block 14c is fitted and positioned. A double-sided tape 30 is adhered to the surface 26a forming the cut portion 26 in the lower block 14c. Further, a positioning protrusion 32 is formed on the upper surface of the lower block 14c.

Next, as shown in FIG. 3B, each corner of the solar cell panel 12 is placed on the four lower blocks 14c installed on the assembly base 28. As a result, each corner of the back surface (or lower surface) of the solar cell panel 12 is quickly adhered and fixed to the lower block 14c by the double-sided tape 30.

Subsequently, the upper block 14d is placed on the lower block 14c. A positioning recess 34 is formed on the lower surface of the upper block 14d. Further, for example, a silicone-based adhesive 36 is previously applied to the surface 26b forming the cut portion 26 in the upper block 14d.

When the upper block 14d is superposed on the lower block 14c as described above, as shown in FIG. 3C, the upper block 14d is positioned with each other by fitting (concavo-convex fitting) between the protrusion 32 and the recess 34. In this state, the upper block 14d is adhesively fixed to each corner of the surface (or upper surface) of the solar cell panel 12 by the adhesive 36. In this way, in the two-divided corner block 14A, the lower block 14c and the upper block 14d are integrally fixed to each corner of the solar cell panel 12.

In this way, in the two-divided corner block 14A, the lower block 14c is quickly fixed to the corner of the solar cell panel 12 by the double-sided tape 30, so that the adhesive 36 fixing the upper block 14d is waited to be cured. The solar cell module 10 can be sent to the next step (for example, packing) without any problem.

4 (a) to 4 (c) are views showing stepwise how the integrated corner block 14 shown in FIG. 2 is attached to the solar cell panel 12.

Referring to FIG. 4A, a pair of first jigs 40, a pair of second jigs 42, and first and second positioning walls 44 and 46 are installed on the assembling table 38. Each first jig 40 has a recess 41 having a substantially square shape in a plan view in which the corner block 14 is fitted and positioned. Each pair of second jigs 42 has an L-shape in a plan view, and is arranged at a distance corresponding to the length of one side of the solar cell panel 12. The first positioning wall 44 is arranged between the pair of first jigs 40. Further, the second positioning wall 46 is arranged between one first jig 40 and one second jig 42.

Using such an assembly base 38, the corner block 14 is fixed to the solar cell panel 12 as follows. At this time, it is preferable to apply, for example, a silicone-based adhesive in advance to the inside of the notch 26 of the corner block 14, but instead of or in addition to this, the adhesive is adhered to the corner of the solar cell panel 12. The agent may be applied.

First, the two corner blocks 14 are set in the recesses 41 of the pair of first jigs 40, respectively. Then, as shown in FIG. 4B, the two corners of the solar cell panel 12 are inserted in the arrow K direction into the notches 26 of the two corner blocks 14 set in the pair of first jigs 40. At this time, the first and second positioning walls 44 and 46 come into contact with the two sides orthogonal to each other in the solar cell panel 12. Further, at this time, the two opposing side portions of the solar cell panel 12 come into contact with each other while being sandwiched between the pair of second jigs 42. As a result, the two corner blocks 14 are accurately and accurately fixed to the solar cell panel 12.

Subsequently, as shown in FIG. 4C, the corner blocks 14 are inserted into the remaining two corners of the solar cell panel 12 located between the pair of second jigs 42 from the direction of the arrow M. At this time, the fixed position of the corner block 14 with respect to the solar cell panel 12 is accurately determined by abutting on the side wall surface of the L-shaped second jig 42. In this way, the four corner blocks 14 are adhesively fixed to each corner of the solar cell panel 12.

In the solar cell module 10 in which the corner block 14 (or 14A, the same applies hereinafter) is fixed to each corner of the solar cell panel 12 as described above, as shown in FIG. 1A, the corners of the solar cell panel 12 The portion is covered and protected by the corner block 14. Therefore, it is possible to prevent the glass substrate and the sealing material constituting the corners from being damaged by hitting the corners of the solar cell panel 12 during transportation or installation of the solar cell module 10.

Further, as shown in FIG. 1 (b), according to the packing form 11A formed by stacking a plurality of solar cell modules 10, the corner blocks 14 of the modules 10 are directly fitted to the protrusions 20 and the recesses 22. Prevents horizontal displacement. Therefore, in this state, the plurality of solar cell modules 10 can be stably transported in a stacked state. Further, as compared with the case where each solar cell module 10 is packed individually, by packing the solar cell modules 10 stacked in a plurality of stages together in this way, the amount of packing material used can be significantly reduced. ..

Further, when the solar cell modules 10 are stacked in this way, the corner block 14 has a portion protruding on both side surfaces of the solar cell panel 12, so that there is a gap between the solar cell panels 12 included in each solar cell module 10. Is formed. This gap is set so that the terminal boxes 16 included in each solar cell module 10 do not come into contact with each other. Therefore, in order to protect the terminal boxes 16 from interfering with each other and being damaged between the plurality of stacked solar cell modules, the circumference of each terminal box 16 may be covered with a packing material such as corrugated cardboard, or between the terminal boxes. There is no need to arrange a spacer member in the corrugated cardboard. Therefore, there is an advantage that the labor of packing and the amount of packing material used can be reduced.

Further, as shown in FIG. 1C, the cable 17 and the connector 18 can be held in the groove 24 formed in the corner block 14. Therefore, when a plurality of solar cell modules 10 are stacked or installed as described later, it is possible to prevent the cable 17 or the like from being pinched between the solar cell modules 10 and being damaged.

FIG. 5 is a diagram showing a packing form 11B of the first modification. The packaging form 11B is configured by stacking the solar cell modules 10 in a plurality of stages. In the example shown in FIG. 5, the terminal box 16a of the solar cell module 10 is larger in size than the terminal box 16 described above with reference to FIG. 1 and the like. Therefore, the terminal box 16a has a large protruding dimension toward one surface of the solar cell panel 12. In such a case, it is preferable to arrange the spacer members 48 between the corner blocks 14 of the solar cell modules 10 to be stacked vertically and indirectly stack them. In this case, the thickness dimension of the spacer member 48 is set in consideration of forming a gap so that the terminal box 16a does not interfere with each other. The spacer member 48 is formed with recesses 22a and protrusions 20a that fit into the protrusions 20 and the recesses 22 of the corner blocks 14 located above and below, respectively, on the lower surface and the upper surface. In this case, the corner blocks 14 located above and below are indirectly unevenly fitted to each other via the spacer member 48. As a result, it is possible to maintain a state in which a plurality of solar cell modules 10 are stably stacked.

FIG. 6 is a diagram showing a packing form 11C of the second modification. The packaging form 11C is configured by stacking a plurality of stages of solar cell modules 10 having corner blocks 14B. In this example, the terminal box 16a of the solar cell module 10 has the same size as that of FIG. 5, which is greatly projected on one surface side of the solar cell panel 12. Therefore, the spacer members 48a are arranged between the corner blocks 14B of the plurality of stacked solar cell modules 10 and are stacked so that the terminal boxes 16a do not interfere with each other. Further, in this case, positioning recesses 22 are formed on the upper and lower surfaces of the corner block 14B, and protrusions 20b that fit into the recesses 22 are formed on the upper and lower surfaces of the spacer member 48a. When the positioning recesses 22 are formed on the upper and lower surfaces of the corner blocks 14B in this way, it is preferable to stack the corner blocks 14B with each other by using the spacer members 48a having the protrusions 20b on the upper and lower surfaces. In this case, the corner blocks 14B located above and below are indirectly unevenly fitted with each other via the spacer member 48a. As a result, the terminal boxes 16a do not interfere with each other, and a plurality of solar cell modules 10 can be stably stacked.

FIG. 7 is a diagram showing a packing form 11D of the third modification. The packaging form 11D is configured by stacking a plurality of stages of solar cell modules 10 having corner blocks 14B. In this example, as in the case of FIG. 6, positioning recesses 22 are formed on the upper and lower surfaces of the corner block 14B, respectively. Further, the terminal box 16 is the same as the solar cell module 10 described above with reference to FIG. 1 and the like, and is a type in which the amount of protrusion from the surfaces on both sides of the solar cell panel 12 is not so large. Therefore, in this case, the terminal boxes 16 do not interfere with each other even if the spacer member is not interposed in the corner block 14B. However, a positioning member 49 that fits into two opposing recesses 22 of the vertically stacked corner blocks 14B is used so that the corner blocks 14B of the stacked solar cell modules 10 do not shift in the horizontal direction. Is preferable. In this case, the corner blocks B located above and below are indirectly unevenly fitted with each other via the positioning member 49.

FIG. 8 is a diagram showing a packing form 11E of the fourth modification. The packaging form 11E is configured by stacking a plurality of stages of solar cell modules 10 having corner blocks 14C. The corner block 14C has protrusions 20 for positioning on the upper and lower surfaces, respectively. In this case, in order to stably stack the plurality of solar cell modules 10, it is preferable to use a spacer member 48b having recesses 22a fitted to the protrusions 20 on the upper and lower surfaces. In this case, the corner blocks 14C located above and below are indirectly unevenly fitted with each other via the spacer member 48b. Further, in this case, in order to stably mount the lowermost solar cell module 10 on a tray or pallet (not shown), a spacer member 48b is also arranged under the corner block 14C of the lowermost solar cell module 10. Is preferable.

Next, with reference to FIGS. 9 to 21, a photovoltaic power generation device including the above-mentioned solar cell module 10 will be described. FIG. 9 is a diagram showing a support structure 50 of the solar cell module 10 composed of a vertical gutter and a horizontal gutter formed in a grid pattern. 10 (a) is an enlarged view of a part of the support structure 50 shown in FIG. 9, FIG. 10 (b) is a view taken along the arrow C in FIG. 10 (a), and FIG. 10 (c) is FIG. It is a D arrow view view in (a).

As shown in FIGS. 9 and 10A, the support structure 50 includes a plurality of vertical gutters 52 (first gutters) arranged parallel to each other along the first direction, and the first direction. It includes a plurality of lateral gutters 54 (second gutters) arranged parallel to each other along orthogonal directions. Both ends of the horizontal gutter 54 are connected and fixed to the vertical gutter 52 by, for example, welding. Here, the first and second directions can be two directions orthogonal to each other on the horizontal plane. As a result, the support structure 50 can be used in a horizontally installed photovoltaic power generation device in which the solar cell module 10 is installed along a horizontal plane. However, the support structure may be extended along a surface slightly inclined from the horizontal plane.

As shown in FIGS. 10B and 10C, the vertical gutter 52 is a long member having a substantially C-shaped cross section. The vertical gutter 52 is formed of, for example, C-shaped steel. Similarly, the lateral gutter 54 is also a long member having a substantially C-shaped cross section. In the present embodiment, as the horizontal gutter 54, a C-shaped steel that is narrower and thinner than the vertical gutter 52 can be used. The ends of the horizontal gutter 54 are connected while resting on the vertical gutter 52. A step 53 corresponding to the thickness of the horizontal gutter 54 is formed between the upper surface of the horizontal gutter 54 and the upper surface of the vertical gutter 52.

Water such as rainwater that has flowed into the horizontal gutter 54 can flow into the vertical gutter 52. The water that has flowed directly into the vertical gutter 52 or from the horizontal gutter 54 flows along the longitudinal direction of the vertical gutter 52. In this way, the support structure 50 is configured as a rectangular frame forming a grid pattern by the vertical gutter 52 and the horizontal gutter 54, supports the solar cell panel 12 included in the photovoltaic power generation device as described later, and also supports rainwater or the like. Functions as a gutter for draining water.

11 (a) is a side view showing a state in which the spacer member 56 is arranged on the vertical gutter 52 in the support structure 50 shown in FIG. 9, and FIG. 11 (b) is an E in FIG. 11 (a). It is an arrow view. The support structure 50 further includes a spacer member 56. As shown in FIG. 11, the spacer member 56 has a substantially U-shaped cross section. Further, the spacer member 56 is formed to have substantially the same width as the upper overhanging portion 52a of the vertical gutter 52, and extends along the upper overhanging portion 52a. The spacer member 56 is made of, for example, a metal material. Further, the spacer member 56 is formed to have substantially the same thickness as the lateral gutter 54. As a result, the step 53 between the vertical gutter 52 and the horizontal gutter 54 is eliminated, and the upper surfaces of the spacer member 56 and the horizontal gutter 54 are substantially flush with each other (that is, at substantially the same height position).

FIG. 12 is a diagram showing a state in which the frameless solar cell panel 13 is installed on the support structure 50 shown in FIG. In FIG. 12 (the same applies to FIGS. 14, 17, 18, and 21), the solar cell panel 13 is hatched for ease of understanding. Here, as the solar cell panel 13, the same one as the solar cell panel 12 of the solar cell module 10 described above can be used. However, the solar cell panel 13 is not provided with a corner block.

When the solar cell panel 13 is installed using the support structure 50 described above with reference to FIG. 11, the fixing member 58 is erected on the inner bottom surface of the lateral gutter 54 as shown in FIG. The lower end of the fixing member 58 is fixed to the lateral gutter 54 by, for example, welding. Further, the upper end portion of the fixing member 58 has a shape bent substantially along the horizontal direction. Although not shown, the fixing member 58 is also erected on the inner bottom surface of the vertical gutter 52.

Subsequently, the solar cell panel 13 is arranged in a state where the peripheral portion is placed on the lateral gutter 54 and the spacer member 56. Then, the fixing plate 60 is fixed to the upper end portion of the fixing member 58 by, for example, screwing, straddling each peripheral edge portion of the two adjacent solar cell panels 13. The fixing plate 60 is made of, for example, a metal plate. As a result, the peripheral edge of the solar cell panel 13 is pressed by the fixing plate 60, and the solar cell panel 13 is fixed to the lateral gutter 54 (that is, the support structure 50).

However, in this case, the metal lateral gutter 54 and the spacer member 56 come into direct contact with the back surface of the solar cell panel 13. Further, the fixing plate 60 made of a metal plate comes into direct contact with the surface of the solar cell panel 13. Then, the protective member such as the glass substrate constituting the front and back surfaces of the solar cell panel 13 may be damaged or cracked.

Therefore, in order to prevent such inconvenience, it is conceivable to fix the solar cell panel 13 via a flexible packing member as shown in FIG. 13 (a) is a view showing a state in which the packing member is arranged on the support structure 50 shown in FIG. 11, and FIG. 3 (b) is a view taken along the line F in FIG. 13 (a). In FIG. 13 (also in FIGS. 17, 18 and 21), the packing member is shown in stippling.

As shown in FIGS. 13 (a) and 13 (b), packing members 62 are arranged on the upper surfaces of the lateral gutter 54 and the spacer member 56. The packing member 62 is made of a flexible material such as rubber. Further, the packing member 62 is attached and fixed by, for example, an adhesive layer on the lower surface thereof.

FIG. 14 is a diagram showing a state in which the frameless solar cell panel 13 is installed on the support structure 50 shown in FIG. The peripheral edge of the solar cell panel 13 is placed on the packing member 62 arranged as described above. Then, the fixing plate 60 is attached to the upper end portion of the fixing member 58 erected on the inner bottom surface of the lateral gutter 54 in the same manner as described above with reference to FIG. In this case, a flexible packing member 64 made of, for example, rubber is interposed between the surface peripheral edge of the solar cell panel 13 and the fixing plate 60. As a result, the back surface and the peripheral edge of the front surface of the solar cell panel 13 come into contact with the lateral gutter 54, the spacer member 56, and the fixing plate 60 via the packing members 62 and 64. Therefore, in this case, the protective members such as the glass substrate constituting the front and back surfaces of the solar cell panel 13 are not damaged.

However, when the solar cell panel 13 is fixed as shown in FIG. 14, the packing members 62 and 64 deteriorate due to long-term use, and water leakage and rattling of the solar cell panel occur due to loss of flexibility. Is a concern. In particular, the packing member 62 on the support structure 50 tends to be deteriorated as the weight of the solar cell panel 13 continues to act.

Therefore, by configuring the photovoltaic power generation device using the solar cell module 10 of the present embodiment with reference to FIGS. 1 to 8, water leakage and rattling due to deterioration of the packing member as described above can be suppressed. can do.

FIG. 15 is a plan view showing a state in which the solar cell module 10 of the present embodiment shown in FIG. 1 is installed on the support structure 50 shown in FIG. FIG. 16 is a plan view showing a horizontally installed photovoltaic power generation device 100 configured by fixing the solar cell module 10 shown in FIG. 15 to a support structure 50 by a fixing plate 60.

As shown in FIG. 15, the solar cell module 10 of this embodiment is installed on the support structure 50. At this time, the solar cell module 10 is supported by the lower surface of the corner block 14 fixed to the corner of the solar cell module 10 resting on the inner bottom surface 54a of the lateral gutter 54. Then, as shown in FIG. 16, the fixing plate 60 is attached to the upper end of the fixing member 58 erected on the lateral gutter 54. Further, the fixing plate 61 is attached to the upper end of the fixing member 58 erected on the vertical gutter 52.

FIG. 17 is a sectional view taken along line GG in FIG. As shown in FIG. 17, the lower surface of the corner block 14 of the solar cell module 10 is supported by being placed on the inner bottom surface 54a of the lateral gutter 54. Further, a flexible packing member 62 is arranged between the back surface of the solar cell panel 12 and the lateral gutter 54 and the spacer member 56. Further, the corner block 14 of the solar cell module 10 is pressed and fixed by the fixing plates 60 and 61 via the flexible packing member 64. The packing member may be provided only between the edge portion of the solar cell panel 12 and the fixing plates 60 and 61 at a position other than the corner block 14.

According to the photovoltaic power generation device 100 configured in this way, the weight of the solar cell module 10 is supported by the support structure 50 including the lateral gutter 54. Therefore, since the weight of the solar cell module 10 does not act on the packing member 62 arranged in contact with the back surface of the solar cell panel 12, it is possible to suppress the occurrence of water leakage and rattling due to deterioration of the packing member 62.

FIG. 18 is a diagram corresponding to FIG. 17, showing an example in which the height adjusting member 19 is connected to the lower surface of the corner block 14. As shown in FIG. 18, the height adjusting member 19 may be connected to the lower surface of the corner block 14. The height adjusting member 19 is fixed by adhesion, screwing, or the like in a state of being positioned with respect to the corner block 14 by, for example, uneven fitting. By using the height adjusting member 19 in this way, the installation height of the solar cell module 10 with respect to the support structure 50 can be easily adjusted.

In the above description, an example in which the corner block 14 is supported on the inner bottom surface 54a of the lateral gutter 54 has been described, but the present invention is not limited to this. The corner block 14 may be placed on the inner bottom surface of the vertical gutter 52 to support the solar cell module 10.

Next, a modified example of the corner block will be described with reference to FIGS. 19 to 21. FIG. 19 is a top view (a), a front view (b), and a side view (c) showing the corner block 14D of the third modification. 20 is a front view (a) and a side view (b) showing a state in which the corner blocks 14D shown in FIG. 19 are stacked. FIG. 21 is a diagram corresponding to FIG. 17, showing a state in which the solar cell module 10 having the corner block 14D shown in FIG. 19 is installed in the support structure 50 shown in FIG.

As shown in FIGS. 19 to 21, the corner block 14D has an upper portion 66 and a lower portion 68 in the vertical direction in the installed state of the photovoltaic power generation device 100. The upper portion 66 has a rectangular parallelepiped shape in substantially the same manner as the corner block 14 in the above-described embodiment, and a notch 26 that opens to two side wall surfaces is formed. The notch 26 is a recess into which the corner of the solar cell panel 12 is inserted and fixed.

The lower portion 68 of the corner block 14D is a portion that rests on the inner bottom surface 54a of the lateral gutter 54, and is a plate whose thickness along the width direction of the lateral gutter 54 is thinner than the length along the longitudinal direction of the lateral gutter 54. It is formed in a shape. Since the lower portion 68 of the corner block 14D is formed in a plate shape in this way, when it is placed on the inner bottom surface 54a of the lateral gutter 54 as shown in FIG. 21, it is formed inside the lateral gutter 54. It is possible to suppress the decrease in the flow path area and ensure a smooth flow of water.

Further, the plate-shaped lower portion 68 is formed so as to project outward from the side surface of the substantially rectangular parallelepiped upper portion 66, and a housing portion 69 for accommodating the upper portion of another corner block 14D is formed inside the plate-shaped lower portion 68. As a result, as shown in FIG. 20, a plurality of corner blocks 14D can be neatly and compactly stacked in a state where the upper portion 66 of another corner block 14D is accommodated in the accommodating portion 69. At this time, the upper portion 66 accommodated in the accommodating portion 69 is positioned in contact with the side wall 69a included in the lower portion 68.

Next, the vertically installed photovoltaic power generation device 200 will be described with reference to FIGS. 22 to 24. 22A and 22B are views showing a state in which a vertically installed solar power generation device 200 is installed, in which FIG. 22A is a front view, FIG. 22B is a sectional view taken along line HH in FIG. 22A, and FIG. ) Is a cross-sectional view taken along the line II. 23 is a view showing the installation completion state of the photovoltaic power generation device 200 shown in FIG. 22, where FIG. 23A is a front view and FIG. 23B is a sectional view taken along line JJ in FIG. 22A.

The solar cell module 10 is the same as that described with reference to FIG. 1 and the like, and the description thereof will be omitted here by using the same reference numerals.

The rectangular frame 70 has a lower frame 72 having a substantially U-shaped cross section, two vertical frames 74 having a substantially U-shaped cross section erected at both ends of the lower frame 72, and the upper ends of the two vertical frames 74. Includes an upper cover 76 that is mounted parallel to the lower frame over. 22 and 23 show an example in which two rectangular frames 70 are connected side by side with the lower frame 72 in common.

The lower frame 72 and the vertical frame 74 are formed of, for example, U-shaped steel, and are connected to each other by welding or the like. Similarly, the upper cover 76 is also made of, for example, U-shaped steel.

As shown in FIGS. 22A and 22B, the solar cell module 10 is inserted between the two vertical frames 74 in the direction of the arrow from above and installed. At this time, the corner block 14 of the solar cell module 10 is inserted while contacting the facing side wall surfaces of the vertical frame 74. Therefore, the solar cell panel 12 does not come into contact with the vertical frame 74, and it is possible to prevent the solar cell panel 12 from being damaged during installation. Further, when the solar cell module 10 is inserted up to the lower frame 72, the corner block 14 fixed to the corner of the solar cell panel 13 comes into contact with the inner bottom surface of the lower frame 72. In this state, the lower edge portion of the solar cell panel 12 is located upwardly away from the inner bottom surface when the corner block 14 comes into contact with the inner bottom surface of the lower frame 72. Therefore, it is possible to effectively prevent the corners and the lower edge of the solar cell panel 12 from colliding with the inner bottom surface of the lower frame 72 and being damaged.

As described above, the solar cell module 10 is installed inside the lower frame 72 and the vertical frame 74. At this time, the cable 17 may be fitted into the groove 24 (see FIG. 2) recessed in the corner block 14. After that, the upper cover 76 is covered between the upper ends of the four vertical frames 74, and is fixed by, for example, screwing. The upper cover 76, like the lower frame 72, is also formed as a member common to the two rectangular frames 70.

Even if the filler 78 is packed and sealed, water 79 may collect on the inner bottom surface 73 of the lower frame 72. In this case, in the solar cell panel 13 to which the corner block or the frame is not attached, the lower edge portion thereof may be immersed in the accumulated water 79 and may invade the inside of the panel.

On the other hand, as shown in FIG. 24A, in the photovoltaic power generation device 200 using the solar cell module 10 of the present embodiment, the solar cell panel 12 is formed by the corner block 14 fixed to the corner of the solar cell panel 12. The lower edge is held at a position upward away from the inner bottom surface 73. Therefore, even when the water 79 collects in the lower frame 72, the lower edge portion of the solar cell panel 13 is less likely to be immersed in the water 79, and the possibility of the water entering the inside of the solar cell panel 12 can be reduced. Although not shown, it is preferable to form a drainage hole penetrating in the vicinity of the inner bottom surface 73 on the side wall of the lower frame 72.
