[0009] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the following drawings, the same components are denoted by the same reference numerals.

[0010] A roofing material-integrated solar cell module according to an embodiment of the present disclosure may be installed on the top surface of a structure such as a house. The top surface may be, for example, an inclined surface, a horizontal surface, etc. An inclined surface is a surface that is inclined relative to a horizontal surface. The top surface may be, for example, a main surface of a sheathing board. The main surface is the surface with the largest area in a cube. The sheathing board may be covered with a roofing material for waterproofing.

[0011] The multiple roofing-integrated solar cell modules may be arranged two-dimensionally on the top surface of the structure. A two-dimensional arrangement means that the centers of gravity of the multiple roofing-integrated solar cell modules are arranged two-dimensionally. Therefore, even if two adjacent roofing-integrated solar cell modules partially overlap each other in a direction perpendicular to the two-dimensional plane, this arrangement may be considered two-dimensional. The multiple roofing-integrated solar cell modules may be arranged side by side in the girder direction. Multiple rows formed by multiple roofing-integrated solar cell modules arranged side by side in the girder direction may be arranged side by side from the ridge side to the eave side. The multiple roofing-integrated solar cell modules may be arranged side by side or offset from each other in the direction from the ridge side to the eave side. Furthermore, the eave-side end of any roofing-integrated solar cell module may be arranged so that it overlaps the ridge-side end of an adjacent roofing-integrated solar cell module on the eave side.

[0012] As shown in FIG. 1 , a roofing-material-integrated solar cell module 10 includes a first number of roofing tile bodies 11 and one panel unit 12. The roofing-material-integrated solar cell module 10 may further include a holding member 13. The first number is any integer equal to or greater than two. The first number is not limited to a fixed number. For example, roofing-material-integrated solar cell modules 10 having different first numbers may be used depending on the length of the girder direction of the structure on which the roofing-material-integrated solar cell module 10 is installed. For example, a mixture of roofing-material-integrated solar cell modules 10 having first numbers that are different from the first number of any roofing-material-integrated solar cell module 10 and are equal to or greater than two may be used. For example, a mixture of roofing-material-integrated solar cell modules 10 having different numbers, each of which is equal to or greater than two, may be used. In the rest of this specification, a roofing-material-integrated solar cell module 10 including two roofing tile bodies 11 will be described as an example.

[0013] The roofing-integrated solar cell module 10 has a first direction and a second direction that are orthogonal to each other. The roofing-integrated solar cell module 10 may also have a third direction that is perpendicular to both the first and second directions. The first direction is a direction parallel to the longitudinal direction of the structure when the roofing-integrated solar cell module 10 is placed in a normal position on the top surface of the structure. The normal position refers to the correct position determined in the design. The second direction is a direction parallel to the direction from the eaves side to the ridge side of the structure when the roofing-integrated solar cell module 10 is placed in a normal position on the top surface of the structure. The direction assumed for placement from the eaves side to the ridge side may include not only a direction strictly parallel to the rafter direction, but also a direction inclined relative to the rafter direction. The third direction is a direction parallel to the vertical downward direction when the roofing-integrated solar cell module 10 is placed in a normal position on the top surface of the structure. The vertically downward direction is a direction that includes the vertically downward direction as a vector component.

[0014] The roof tile body 11 may have an overall rectangular shape with two sides parallel to the first direction and two sides parallel to the second direction. As shown in FIG. 2 , the roof tile body 11 may include a support portion 14, a first portion 15, a second portion 16, and a hook 17. The roof tile body 11 has a support surface ss. The support surface ss may be the surface of the support portion 14 on the side opposite the third direction. The support surface ss is a surface parallel to the first direction and the second direction. The first number of roof tile bodies 11 may be positioned side by side in the first direction in the roofing material-integrated solar cell module 10 so that their support surfaces ss are flush with each other. In other words, the first number of roof tile bodies 11 may be positioned side by side in the first direction so that their support surfaces ss are located in the same plane. The first number of roof tile bodies 11 may be positioned side by side in the first direction in the roofing material-integrated solar cell module 10 so that they are in close contact with each other in the first direction.

[0015] A recess 18 recessed from the support surface ss may be formed in a portion of the support surface ss. In other words, the recess 18 is a recessed portion provided in the support surface ss. The recess 18 may be formed inside the support surface ss in the first direction. Formed inside means that the recess 18 is formed somewhere inside the support surface ss, while the support surface ss is at both ends in the first direction. The recess 18 may be formed at an intermediate position in the first direction. The recess 18 may be groove-shaped extending in the second direction.

[0016] The first portion 15 may be located on the second direction side relative to the support surface ss. As shown in FIG. 3, the first portion 15 may be raised from the support surface ss. As shown in FIG. 2, the first portion 15 may be ridge-shaped extending along the first direction. The second portion 16 may be located on the opposite side of the second direction relative to the support surface ss. As shown in FIG. 3, the second portion 16 may be raised from the support surface ss. As shown in FIG. 2, the second portion 16 may extend along the first direction.

[0017] As shown in Fig. 3, the entirety of the hook 17 may be located within the recess 18. The hook 17 may be provided on all of the roof tile bodies 11 arranged side by side in the first direction in the roofing material-integrated solar cell module 10, or on some of the roof tile bodies 11. The hook 17 may be located on the opposite side of the first portion 15 in the second direction.

[0018] The hook 17 may have a wall surface that defines a space on the second direction side within the recessed portion 18. The hook 17 may also have a wall surface that defines a space on the third direction side within the recessed portion 18. In other words, a gap may be provided between the hook 17 and the bottom surface of the recessed portion 18. For example, the hook 17 may be a plate-like member that is fixed to the support portion 14 so as to be parallel to the first direction and the second direction while having a gap from the bottom surface of the recessed portion 18. For example, as shown in FIG. 4, the hook 17 may be a claw-like member that is fixed to the support portion 14 so as to be open on the second direction side at the bottom surface of the recessed portion 18.

[0019] As shown in FIG. 1, the panel unit 12 is positioned in the roofing material-integrated solar cell module 10 so as to straddle at least two of the first number of roof tile bodies 11 positioned side by side in the first direction. Furthermore, the panel unit 12 may be positioned so as to straddle all of the first number of roof tile bodies 11 positioned side by side in the first direction. The panel unit 12 may be positioned between the first portion 15 and the second portion 16 of the roof tile body 11 in the second direction. As shown in FIG. 5, the panel unit 12 may be configured to include a main body portion 19, a hooking fixture 20, and a terminal box 21.

[0020] The main body 19 is flat and parallel to the first and second directions. A solar cell is provided in the main body 19. The main body 19 may receive light and generate electricity mainly on the surface opposite to the third direction. The panel 12 may be supported by the roof tile body 11 in surface contact with the support surface ss of the main body 19.

[0021] The length of the main body 19 in the first direction may be less than or equal to the total length of the first number of roofing tile bodies 11 arranged side by side in the first direction in the roofing material-integrated solar cell module 10. Alternatively, the length of the main body 19 in the first direction may be greater than or equal to the total length minus a margin. The margin is a length provided to the roofing tile body 11 to reduce damage caused by a collision of the main body 19 during construction to install the roofing material-integrated solar cell module 10 on the upper surface. The margin is, for example, 10 mm.

[0022] The hooking device 20 may be provided on the surface of the main body 19 facing the third direction. The hooking device 20 may be provided in the roofing material-integrated solar cell module 10 at the same position in the first direction as the hooking device 17 of the roof tile body 11.

[0023] The hooking fixture 20 may be hooked to the hooking fixture 17. More specifically, the hooking fixture 20 may be hooked to the hooking fixture 17 in the roofing-integrated solar cell module 10 from the second direction side in a direction along the second direction. In other words, the hooking fixture 20 may be hooked to the hooking fixture 17 so as to suppress displacement of the panel unit 12 in the direction opposite the second direction relative to the roof tile body 11. Furthermore, the hooking fixture 20 may be hooked to the hooking fixture 17 in the roofing-integrated solar cell module 10 from the third direction side in a direction along the third direction. In other words, the hooking fixture 20 may be hooked to the hooking fixture 17 so as to suppress displacement of the panel unit 12 in the direction opposite the third direction relative to the roof tile body 11. The hooking fixture 20 may be, for example, a claw-like member fixed to the main body 19 so that the side opposite the second direction is open.

[0024] The hooked device 20 may be hooked to the hooking device 17 by displacing the panel portion 12 from the second direction side in the direction opposite to the second direction while the main body portion 19 is in surface contact with the support surface ss.

[0025] The terminal box 21 may be provided on the surface of the main body 19 facing in the third direction. The terminal box 21 may be provided in the roofing material-integrated solar cell module 10 at the same position in the first direction as the recessed portion 18 of the roof tile body 11. The terminal box 21 may be housed in the recessed portion 18 of the roofing material-integrated solar cell module 10. In other words, the terminal box 21 may be located in the recessed portion 18 of the roofing material-integrated solar cell module 10 without interfering with the surface contact of the support surface ss with the main body 19, specifically, without interfering with the bottom surface of the recessed portion 18. Because the terminal box 21 is housed in the recessed portion 18, the height of the terminal box 21 from the surface of the main body 19 may be shorter than the depth of the recessed portion 18 of the roof tile body 11. The terminal box 21 may output power generated by light received by the main body 19 to the outside.

[0026] In the roofing material-integrated solar cell module 10, an air layer may be partially provided between the roof tile body 11 and the panel portion 12. The air layer may be a layer formed by air inside the recessed portion 18, for example.

[0027] 1, the holding member 13 may hold the end portion of the panel portion 12 on the second direction side. The holding member 13 may be fixed to the first portion 15. The holding member 13 may be fixed to the first portion 15 while holding the panel portion 12, and the panel portion 12 may be fixed to the roof tile body 11 by the engagement of the hook 17 and the hooked portion 20.

[0028] The holding of the panel portion 12 by the holding member 13 should at least prevent the end portion of the panel portion 12 on the second direction side from coming off in the direction opposite to the third direction. For example, as shown in Fig. 6, the holding member 13 may hold the panel portion 12 by making surface contact with the end portion of the panel portion 12 from the side opposite to the third direction and pressing it in the third direction. Alternatively, as shown in Fig. 7, the holding member 13 may have a frame-shaped insertion portion 23 that covers the side surface and both main surfaces at the end portion on the second direction side of the main body portion 19, and hold the panel portion 12 by inserting the main body portion 19 into the insertion portion 23.

[0029] Any fixing mechanism may be used to fix the holding member 13 to the first portion 15. For example, as described below, nails may be inserted through holes formed in the holding member 13 and the first portion 15 and driven into the upper surface of the structure, thereby fixing the roofing material-integrated solar cell module 10 to the upper surface and fixing the holding member 13 to the first portion 15. Alternatively, the holding member 13 may be fixed to the first portion 15 by attaching an adhesive sheet between the holding member 13 and the first portion 15.

[0030] The holding member 13 may be positioned so as to straddle all of the first number of roofing tile bodies 11 positioned side by side in the first direction in the roofing material-integrated solar cell module 10. Alternatively, the holding member 13 may be positioned so as not to straddle some of the first number of roofing tile bodies 11 positioned side by side in the first direction. The holding member 13 may be divided in the first direction in the roofing material-integrated solar cell module 10. In other words, in a single roofing material-integrated solar cell module 10, multiple holding members 13 may hold one panel unit 12 at different positions in the first direction.

[0031] The length of the holding member 13 in the first direction may be equal to or greater than the length of the panel unit 12 in the first direction. Alternatively, the length of the holding member 13 in the first direction may be equal to or less than the length in question, i.e., the length of the panel unit 12 in the first direction plus the protection length. The protection length is a length that provides an extra margin to the holding member 13 to reduce damage to the main body unit 19 due to the main body unit 19 colliding with the surrounding area during construction to install the roofing material-integrated solar cell module 10 on the upper surface. The protection length is, for example, 5 mm.

[0032] 1 and 2, the holding member 13 and the first portion 15 have holes 22 that communicate with each other in the roofing material-integrated solar cell module 10. As described above, the roofing material-integrated solar cell module 10 may be fixed to the upper surface of a structure by driving nails into the holes 22 while the holes 22 of the holding member 13 and the first portion 15 are aligned.

[0033] The roofing-integrated solar cell module 10 configured as described above includes a first number of roofing tile bodies 11 (two or more), each having a support surface ss parallel to a first direction and a second direction perpendicular to the first direction, and positioned side by side in the first direction so that the support surfaces ss are flush with each other; and a single panel unit 12, having a solar cell mounted on a flat main body 19 parallel to the first and second directions, positioned across at least two of the first number of roofing tile bodies 11 positioned side by side in the first direction and supported by the main body 19 in surface contact with the support surface ss. In conventional roofing-integrated solar cell modules, if the roofing tile body and the panel unit are integrated at the time of shipment, there is a risk of the panel unit being damaged during loading for transportation of the roofing-integrated solar cell module. Specifically, roofing-integrated solar cell modules are expected to be transported stacked together. During such transportation, roofing tile bodies of other roofing-integrated solar cell modules may collide with the panel unit during loading. Furthermore, when roofing-material-integrated solar cell modules are stacked, stress may concentrate on a portion of the panel portion. Because roofing tiles are generally harder than the panel portion, collisions or concentrated stress can damage the panel portion. Thus, roofing-material-integrated solar cell modules, in which the roofing tiles and panel portion are integrated at the time of shipment, have room for improvement in transportability. In response to this issue, the roofing-material-integrated solar cell module 10 having the above-described configuration allows the roofing tiles 11 and panel portion 12 to be transported separately during transportation, improving transportability. Furthermore, a roofing-material-integrated solar cell module in which the roofing tiles and panel portion are separate at the time of shipment but are composed of a single roofing tile body whose length in the first direction is the same as that of the panel portion, is considered as a reference embodiment. However, in the roofing-material-integrated solar cell module of the reference embodiment, the roofing tiles are long and may be heavier than regular roofing tiles. Therefore, the roofing-material-integrated solar cell module of the reference embodiment requires a lot of effort to transport to the construction site, carry onto the roof, and handle during construction. Thus, the roofing-material-integrated solar cell module of the reference embodiment has room for improvement in transportability. From this perspective, the roofing material-integrated solar cell module 10 having the above-described configuration can be composed of multiple roof tile bodies 11, so that roof tile bodies 11 that are approximately the same size or weight as a conventional single roof tile can be used.Therefore, the roofing material-integrated solar cell module 10 can be improved in transportability. Furthermore, in the roofing material-integrated solar cell module of the reference embodiment, it is assumed that panel units with different lengths in the first direction are combined to match the length of the structure in the girder direction and installed on the top surface of the structure. Therefore, the roofing material-integrated solar cell module of the reference embodiment requires multiple types of roofing tiles with different lengths in the first direction to match the lengths of each panel unit. Therefore, in the roofing material-integrated solar cell module of the reference embodiment, it is necessary to identify and manage each type of roofing tile during transportation. Thus, the roofing material-integrated solar cell module of the reference embodiment has room for improvement in transportability for management purposes. From this perspective, the roofing material-integrated solar cell module 10 having the above-described configuration can be composed of multiple roofing tile units 11, eliminating the need for roofing tiles for each type of panel unit 12. Therefore, the roofing material-integrated solar cell module 10 can be improved in transportability.

[0034] Furthermore, with the above-described configuration, the roofing-material-integrated solar cell module 10 can position the light-receiving surface of the panel unit 12 between adjacent roofing tile bodies 11 in the first direction, thereby increasing the ratio of the solar cell area to the light-receiving surface area. Therefore, the roofing-material-integrated solar cell module 10 can generate more power than a configuration in which a panel unit 12 is placed for each roofing tile body 11. Furthermore, with the above-described configuration, the roofing-material-integrated solar cell module 10 can reduce the total length of wiring electrically connecting the panel units 12 between adjacent roofing tile bodies 11 in the first direction, compared to a configuration in which a panel unit 12 having the same length in the first direction as each roofing tile body 11 is installed for every first number of roofing tile bodies 11 and the panel units 12 are connected by wiring, thereby reducing losses due to electrical resistance. Furthermore, since the roofing-material-integrated solar cell module 10 integrates the panel units 12 in a manner that supports them in surface contact with the support surface ss of the roofing tile body 11, the support surface ss can support a positive pressure load applied to the panel unit 12. Therefore, the strength of the roofing material-integrated solar cell module 10 can be improved. Furthermore, in the roofing material-integrated solar cell module 10, the panel portion 12 having the flat main body portion 19 is supported on the support surface ss of the roof tile body 11, which can prevent the panel portion 12 from appearing to float above the roof tile body 11. Therefore, the roofing material-integrated solar cell module 10 can improve the sense of unity between the roof tile body 11 and the panel portion 12. As a result, the roofing material-integrated solar cell module 10 can improve its aesthetic appearance.

[0035] Furthermore, in roofing material-integrated solar cell module 10, the length in the first direction of main body 19 is less than or equal to the total length of the first number of roof tile bodies 11 arranged side by side in the first direction, and is greater than or equal to the total length minus an allowance. With this configuration, roofing material-integrated solar cell module 10 can further expand the light-receiving surface of panel unit 12 compared to a configuration in which the light-receiving surface of panel unit 12 is simply disposed between roof tile bodies 11 adjacent in the first direction. Therefore, roofing material-integrated solar cell module 10 can further increase the amount of power generated and reduce the possibility of damage to panel unit 12 due to a collision with main body 19 during installation.

[0036] Furthermore, in the roofing material-integrated solar cell module 10, the roof tile body 11 has a first portion 15 located on the second direction side of the support surface ss and protruding from the support surface ss, and a second portion 16 located on the opposite side of the second direction of the support surface ss and protruding from the support surface ss, and the panel portion 12 is located between the first portion and the second portion. With this configuration, the roofing material-integrated solar cell module 10 can be visually integrated.

[0037] Moreover, the roofing material-integrated solar cell module 10 further includes a holding member 13 that holds the end of the panel portion 12 on the second direction side and is fixed to the first portion 15. With this configuration, the roofing material-integrated solar cell module 10 can firmly fix the panel portion 12 to the roof tile body 11.

[0038] Furthermore, in roofing material-integrated solar cell module 10, holding member 13 is positioned so as to straddle all of the first number of roofing tiles 11. With this configuration, roofing material-integrated solar cell module 10 can be prevented from breaking apart and scattering partially even if a strong localized force is applied when it is subjected to negative wind pressure while installed on the top surface of a structure.

[0039] Furthermore, in roofing material-integrated solar cell module 10, the length in the first direction of holding member 13 is equal to or greater than the length in the first direction of panel portion 12 and equal to or less than said length plus the protection length. With this configuration, roofing material-integrated solar cell module 10 can more firmly fix panel portion 12 to roof tile body 11, and can reduce damage to main body portion 19 caused by collision of main body portion 19 with surrounding objects during installation.

[0040] Furthermore, in roofing material-integrated solar cell module 10, holding member 13 and first portion 15 have hole portions 22 that communicate with each other. With this configuration, roofing material-integrated solar cell module 10 can be fixed to a structure and holding member 13 to first portion 15 by driving nails into hole portions 22 after aligning hole portions 22 of holding member 13 and first portion 15.

[0041] Furthermore, in the roofing material-integrated solar cell module 10, the roof tile body 11 has a hook 17 located in a recess 18 formed in part of the support surface ss, on the opposite side of the second direction from the first portion, and the panel portion 12 has a hook receiving portion 20 that hooks onto the hook 17. With this configuration, the roofing material-integrated solar cell module 10 can more firmly connect the roofing material body 11 and the panel portion 12. Therefore, the roofing material-integrated solar cell module 10 can be prevented from breaking apart and scattering even if a strong local force is applied when it is subjected to negative wind pressure.

[0042] Furthermore, in the roofing material-integrated solar cell module 10, the recessed portion 18 is formed at a middle position in the first direction of the support surface ss. With this configuration, the roofing material-integrated solar cell module 10 can simultaneously maximize the width in the first direction of the support surface ss at both ends in the first direction. Therefore, the roofing material-integrated solar cell module 10 can have improved strength at both ends in the first direction.

[0043] Furthermore, in the roofing material-integrated solar cell module 10, the panel section 12 has a terminal box 21 housed in the recess 18. With this configuration, when the roofing material-integrated solar cell module 10 is installed on a structure, if the terminal box 21 catches fire, the roof tile body 11, which is generally made of a non-combustible material, can prevent the falling of fire sources. Therefore, the roofing material-integrated solar cell module 10 can prevent the fire from spreading to the roof sheathing boards and the like located below the roofing material-integrated solar cell module 10.

[0044] Furthermore, in the roofing material-integrated solar cell module 10, an air layer is partially provided between the panel portion 12 and the roof tile body 11. With this configuration, the roofing material-integrated solar cell module 10 can improve its thermal insulation properties.

[0045] In one embodiment, (1) the roofing material-integrated solar cell module is a first number of roof tile bodies, each of which has a support surface parallel to a first direction and a second direction perpendicular to the first direction, and which are positioned side by side in the first direction so that the support surfaces are flush with each other; A solar cell is provided on a flat main body portion parallel to the first direction and the second direction, and the solar cell is positioned so as to straddle at least two of the first number of tile bodies positioned side by side in the first direction, and the solar cell is provided with one panel portion supported in face contact with the support surface on the main body portion.
