Description
- The present invention relates to a solar cell module that holds a solar cell panel so as to surround that solar cell panel using a frame member, and that is installed in an inclined manner on an inclined place such as a roof.
- Generally, solar cell modules are constituted from a solar cell panel and a frame member that holds this solar cell panel. As frame members used for such a solar cell module, members with various structures are known.
- As the structure of the frame member, a frame member is known that has a structure provided with an outer wall perpendicularly formed along one side of the solar cell panel, and a solar cell panel holding unit that is horizontally formed at the upper part of this outer wall, and that has a U-shaped cross section.
- By inserting a side of the solar cell panel into the inside of the U shape of the solar cell panel holding unit whose cross section is U-shaped, the frame member sandwiches the solar cell panel from above and below, forming a solar cell module.
- Further, in order to fix a solar cell module in an installation place, the frame member is provided with a bottom piece that horizontally projects at the lower edge of the outer wall of this frame member. As a solar cell module using such a frame member, various modules have been conventionally known (see FIGS. 1 to 3 of Patent Document 1, for example).
- With the solar cell module described in Patent Document 1, a bottom piece provided at the lower edge of a frame member used for this solar cell module projects from the lower edge of the frame member toward the outer side, which is opposite the solar cell panel side (inner side).
- Note that in this specification, for solar cell modules that hold the periphery of a solar cell panel using a frame member, it is assumed that the “inner side” means the “side in the direction where the solar cell panel is located”, and the “outer side” means the side opposite this “inner side”, that is, the “side in the direction opposite the direction where the solar cell panel is located”.
- Patent document 1: JP H9-96071A
- As described above, with the solar cell module described in Patent Document 1, the bottom piece provided at the lower edge of the frame member used for this solar cell module projects from the lower edge of the frame member toward the outer side, which is opposite the solar cell panel side (inner side).
- Then, to arrange and install such solar cell modules, because of the bottom piece that projects from the lower edge of the frame member toward the outer side, space for disposing this bottom piece is necessary between the solar cell module and the solar, cell module installed adjacently to it. Consequently, this wastes installation space.
- In view of the above, in order to solve this, a frame member has been considered where a bottom piece of the frame member used for fixing a solar cell module projects from the lower edge of the frame member toward the inner side, that is, the solar cell panel side.

FIG. 24 is a partial exploded perspective view showing the structure of asolar cell module 3 b according to a conventional example using such a frame member. Thissolar cell module 3 b according to the conventional example has the following structure. That is, inFIG. 24 , asolar cell panel 9 has a rectangular shape, and using two pairs of members, each pair constituted from amain frame member 50 that holds one side of thissolar cell panel 9 and asub-frame member 70 that holds an adjoining side that adjoins this one side, thesolar cell panel 9 is held. - The above-mentioned
main frame member 50 is constituted from a solar cell panelmain holding portion 51, amain wall portion 52, and amain bottom piece 56. Among these, the solar cell panelmain holding portion 51 has a U-shaped cross section, and inside the U shape, sandwiches one side of thesolar cell panel 9 from above and below so as to hold thesolar cell panel 9. Themain wall portion 52 is connected to the bottom of the solar cell panelmain holding portion 51 and extends downward therefrom. Themain bottom piece 56 is provided to the inner side of the lower edge of themain wall portion 52, extending inward. - The
sub-frame member 70 is constituted from a solar cellpanel sub-holding portion 71, asub-wall portion 72, and asub-bottom piece 76. - Among these, the solar cell
panel sub-holding portion 71 has a U-shaped cross section, and inside the U shape, sandwiches an adjoining side of thesolar cell panel 9 from above and below so as to hold thesolar cell panel 9. Thesub-wall portion 72 is provided with asub-outer wall 73 and asub-inner wall 74 that extend downward with aninternal space 77 sandwiched therebetween, and asub-base piece 75 that closes theinternal space 77 at the lower edges of thesub-outer wall 73 and thesub-inner wall 74, provided under this solar cellpanel sub-holding portion 71, thesub-wall portion 72 being constituted with a side end opening of theinternal space 77 closed by abutting against with themain wall portion 52 of themain frame member 50. Thesub-bottom piece 76 is provided to the inner side of the lower edge of thesub-inner wall 74 of thesub-wall portion 72, extending inward. - With the
solar cell module 3 b according to the above-mentioned conventional example, since thesolar cell panel 9 is held using themain frame member 50 and thesub-frame member 70, when attempting to connect the corners of themain frame member 50 and thesub-frame member 70, as shown inFIG. 24 , themain bottom piece 56 of themain frame member 50 and thesub-bottom piece 76 of thesub-frame member 70 collide with each other, themain frame member 50 and thesub-frame member 70 cannot be connected as they are. - In order to connect the
main frame member 50 and thesub-frame member 70, it is necessary to remove a part of thesub-bottom piece 76 of the sub-frame member 70 (removal necessary portion 78) as shown inFIG. 24 , and, therefore additional man-hours and costs for this task have been necessary. - In view of this, as a solar cell module that does not require the above-mentioned removal work, a new
solar cell module 3 a has been proposed.FIG. 20 is a partial perspective view showing such asolar cell module 3 a,FIG. 21 is a partial exploded perspective view showing the structure of thissolar cell module 3 a,FIG. 22 is a partial plan view thereof andFIG. 23 is a cross-sectional view taken along E-E inFIG. 22 . Note that inFIGS. 20 , 22, and 23, asolar cell panel 9 is omitted. - The new
solar cell module 3 a according to this conventional example is a module using asub-frame member 60, instead of thesub-frame member 70 of thesolar cell module 3 b according to the above-described conventional example. Thesub-frame member 60 has the almost same structure as the above-mentionedsub-frame member 70. - That is, in
FIGS. 20 to 23 , similar to thesub-frame member 70, thissub-frame member 60 is constituted from a solar cellpanel sub-holding portion 61, asub-wall portion 62, and asub-bottom piece 66. Among these, the solar cellpanel sub-holding portion 61 has a U-shaped cross section, and inside the U shape, sandwiches an adjoining side of thesolar cell panel 9 from above and below, holding thesolar cell panel 9. Thesub-wall portion 62 is provided with asub-outer wall 63 and asub-inner wall 64 that extend downward with aninternal space 67 sandwiched therebetween, and asub-base piece 65 that closes theinternal space 67 at the lower edges of thesub-outer wall 63 and thesub-inner wall 64, provided under the solar cellpanel sub-holding portion 61, thesub-wall portion 62 being constituted with a side end opening of theinternal space 67 closed by abutting against with themain wall portion 52 of themain frame member 50. Thesub-bottom piece 66 is provided to the inner side of the lower part of thesub-inner wall 64 of thesub-wall portion 62, extending inward. - As shown in
FIGS. 20 to 23 , thesub-frame member 60 used for the newsolar cell module 3 a according to this conventional example differs from the above-mentionedsub-frame member 70 in that thesub-bottom piece 66 of thissub-frame member 60 is provided extending such that thesub-bottom piece 66 is positioned not at the lower edge of thesub-inner wall 64 of thesub-wall portion 62, but at the lower part of thesub-inner wall 64 of thesub-wall portion 62, and furthermore above themain bottom piece 56 of themain frame member 50, and the lower surface near the side end of thesub-bottom piece 66 abuts against the upper surface near the side end of themain bottom piece 56 of themain frame member 50. - Therefore, with the
solar cell module 3 a, it is possible to connect the corners of themain frame member 50 and thesub-frame member 60 such that thesub-bottom piece 66 of thesub-frame member 60 does not collide with themain bottom piece 56 of themain frame member 50. - Incidentally, there are many cases in which the
solar cell module 3 a according to the conventional example constituted as described above is installed in an inclined manner on an installation place such as an inclined roof, in order to be able to use sunlight efficiently, when used for a residence, for instance. - In this case, as shown in
FIG. 20 , generally, thesolar cell module 3 a is installed in an inclined manner such that one of thesub-frame members 60 is in the lowest position. Note thatFIGS. 20 and 21 show that thesolar cell module 3 a is inclined relative to ahorizontal surface 6 with aninclination angle 7. In this way, if thesolar cell module 3 a is installed in an inclined manner, when it is raining or the like, rainwater flows on themain bottom piece 56 of the inclinedmain frame member 50 from a higher position to a lower position. - The above-described
solar cell module 3 a has a structure in which thesub-bottom piece 66 of thesub-frame member 60 is provided extending such that thesub-bottom piece 66 is positioned above themain bottom piece 56 of themain frame member 50, and the lower surface near the side end of thesub-bottom piece 66 abuts against the upper surface near the side end of themain bottom piece 56 of themain frame member 50. Accordingly, along the stream direction indicated by anarrow 8 as shown inFIG. 20 , rainwater flows from a higher position to a lower position, climbs over the level difference between themain bottom piece 56 and thesub-bottom piece 66, and flows onto the upper surface of thesub-bottom piece 66, from themain bottom piece 56. - The rainwater that has flowed onto this
sub-bottom piece 66 flows into theinternal space 67 of thesub-wall portion 62 through a gap between thesub-inner wall 64 of thesub-wall portion 62 and themain wall portion 52, for instance. As described above, thisinternal space 67 is closed with the side end opening of theinternal space 67 abutting against themain wall portion 52 of themain frame member 50. - Then, the rainwater that has flowed into the
internal space 67 of thissub-wall portion 62 may freeze during periods of extreme cold in cold locations, for instance. As described above, since theinternal space 67 of thesub-wall portion 62 is closed, if rainwater and the like flow into thisinternal space 67 and freeze therein, a gap and the like around theinternal space 67 will freeze clue to this rainwater and the like. Accordingly, thisinternal space 67 becomes a closed space, and during periods of extreme cold in cold locations, for instance, rainwater may freeze and expand in volume, which may damage thesub-wall portion 62 of thesub-frame member 60. Thus, this has been one of the causes of damage to thesolar cell module 3 a. - In view of the above, the present invention has been conceived in order to improve such circumstances, and is aimed at providing a solar cell module that can be prevented from being damaged due to the freezing of rainwater and the like that have flowed in, if the solar cell module is installed in an inclined manner on an inclined place such as a roof.
- As a solar cell module of the present invention, it is possible to constitute two types of solar cell modules, namely a first solar cell module and a second solar cell module. First, the first solar cell module is described.
- The first solar cell module of the present invention holds a solar cell panel so as to surround the solar cell panel on its inner side using a plurality of pairs of members, each pair constituted from a main frame member that holds one side of the solar cell panel and a sub-frame member that holds an adjoining side that adjoins this one side. Further, this first solar cell module is installed in an inclined manner on an inclined place such as a roof, such that one of the sub-frame members is in the lowest position.
- The main frame member of the above-mentioned first solar cell module is provided with a solar cell panel main holding portion, a main wall portion, and a main bottom piece. Among these, the solar cell panel main holding portion has a U-shaped cross section, and sandwiches the one side of the solar cell panel from above and below inside the U shape, holding the solar cell panel. The main wall portion is connected to the bottom of the solar cell panel main holding portion, extending downward therefrom. The main bottom piece is provided to the inner side of the lower edge of the main wall portion, extending inward.
- The sub-frame member of the above-mentioned first solar cell module is provided with a solar cell panel sub-holding portion, a sub-wall portion, and a sub-bottom piece. Among these, the solar cell panel sub-holding portion has a U-shaped cross section, and sandwiches the adjoining side of the solar cell panel from above and below inside the U shape, holding the solar cell panel.
- The sub-wall portion is provided with a sub-outer wall and a sub-inner wall that extend downward with an internal space sandwiched therebetween, and a sub-base piece that closes the internal space at the lower edges of the sub-outer wall and the sub-inner wall, provided under the solar cell panel sub-holding portion, the sub-wall portion being constituted with a side end opening of the internal space closed by abutting against the main wall portion of the main frame member. The sub-bottom piece is provided to the inner side of the lower part of the sub-inner wall of the sub-wall portion, extending inward.
- A feature of the above-mentioned first solar cell module is that the sub-bottom piece is positioned above the main bottom piece of the main frame member, and the lower surface near the side end of the sub-bottom piece abuts against the upper surface near the side end of the main bottom piece of the main frame member, and a water barrier piece bent upward is formed at the inner side edge of the sub-bottom piece.
- Accordingly, if the above-mentioned first solar cell module is installed in an inclined manner, when it is raining, even though rainwater and the like flow on the main bottom piece of the inclined main frame member from a higher position to a lower position, due to the water barrier piece that is bent upward and formed at the inner side edge of the sub-bottom piece of the sub-frame member, rainwater and the like are dammed up and discharged downward from the inner side edge of the main bottom piece of the main frame member. Therefore, rainwater and the like are prevented from flowing onto the sub-bottom piece.
- Consequently, with the above-mentioned first solar cell module, as described above, the side end opening of the internal space of the sub-frame member is closed by abutting against the main wall portion of the main frame member and, further, the flow of rainwater and the like onto the sub-bottom piece is prevented. Therefore, rainwater and the like do not flow into the internal space of the sub-wall portion. Accordingly, it is possible to avoid the sub-wall portion of the sub-frame member being damaged due to rainwater that has flowed into the internal space of the sub-wall portion freezing and expanding in volume. Therefore, if the above-mentioned first solar cell module is installed in an inclined manner on an inclined place such as a roof, it is possible to prevent the module being damaged due to the freezing of rainwater and the like that have flowed into it.
- With the above-mentioned first solar cell module, it is preferable that the water barrier piece is formed such that the angle formed by the water barrier piece and the sub-bottom piece is between 90 degrees and 120 degrees. Further, in this case, it is preferable that the water barrier piece is formed such that the edge surface of this water barrier piece is substantially parallel to the sub-bottom piece. Further, it is preferable that the water barrier piece is formed such that the height to the edge surface of the water barrier piece from the upper surface of the sub-bottom piece is 2 mm or more.
- Next, the second solar cell module of the present invention is descried. Similar to the first solar cell module of the present invention, the second solar cell module of the present invention holds a solar cell panel so as to surround the solar cell panel on its inner side using a plurality of pairs of members, each pair constituted from a main frame member that holds one side of the solar cell panel and a sub-frame member that holds an adjoining side that adjoins the one side. Similar to the first solar cell module, this second solar cell module is installed in an inclined manner on an inclined place such as a roof such that one of the sub-frame members is in the lowest position.
- The main frame member of the above-mentioned second solar cell module is provided with a solar cell panel main holding portion, a main wall portion, and a main bottom piece. Among these, the solar cell panel main holding portion has a U-shaped cross section, and sandwiches the one side of the solar cell panel from above and below inside the U shape, holding the solar cell panel. The main wall portion is connected to the bottom of the solar cell panel main holding portion, extending downward therefrom. The main bottom piece is provided to the inner side of the lower edge of the main wall portion, extending inward.
- The sub-frame member of the above-mentioned second solar cell module is provided with a solar cell panel sub-holding portion, a sub-wall portion, and a sub-bottom piece. Among these, the solar cell panel sub-holding portion has a U-shaped cross section, and sandwiches the adjoining side of the solar cell panel from above and below inside the U shape, holding the solar cell panel.
- The sub-wall portion is provided with a sub-outer wall and a sub-inner wall that extend downward with an internal space sandwiched therebetween, and a sub-base piece that closes the internal space at the lower edges of the sub-outer wall and the sub-inner wall, provided under the solar cell panel sub-holding portion, the sub-wall portion being constituted with a side end opening of the internal space closed by abutting against the main wall portion of the main frame member. The sub-bottom piece is provided to the inner side of the lower part of the sub-inner wall of the sub-wall portion, extending inward.
- A feature of the above-mentioned second solar cell module is that the sub-bottom piece is positioned above the main bottom piece of the main frame member, and is formed such that there is a gap into which water can flow between the sub-bottom piece and the main bottom piece.
- Accordingly, if the above-mentioned second solar cell module is installed in an inclined manner, when it is raining, even though rainwater and the like flow on the main bottom piece of the inclined main frame member from a higher position to a lower position, since there is a gap into which water can flow between the sub-bottom piece of the sub-frame member and the main bottom piece of the main frame member, rainwater and the like flow into the gap into which this water can flow, and are discharged downward. Therefore, rainwater and the like are prevented from flowing onto the sub-bottom piece.
- Consequently, with the above-mentioned second solar cell module, as described above, the side end opening of the internal space of the sub-frame member is closed by abutting against the main wall portion of the main frame member and, further, the flow of rainwater and the like onto the sub-bottom piece is prevented. Therefore, rainwater and the like do not flow into the internal space of the sub-wall portion. Accordingly, it is possible to avoid the sub-wall portion of the sub-frame member being damaged due to rainwater that has flowed into the internal space of the sub-wall portion freezing and expanding in volume. Therefore, if the above-mentioned second solar cell module is installed in an inclined manner on an inclined place such as a roof, it is possible to prevent the module being damaged due to the freezing of rainwater and the like that have flowed into it.
- According to the present invention, with a solar cell module, the lower surface near the side end of a sub-bottom piece of a sub-frame member abuts against the upper surface near the side end of a main bottom piece of a main frame member, and a water barrier piece bent upward is formed at the inner side edge of the sub-bottom piece. Alternatively, the sub-bottom piece of the sub-frame member is positioned above the main bottom piece of the main frame member, and a gap into which water can flow is formed between the sub-bottom piece and the main bottom piece.
- Accordingly, if the solar cell module is installed in an inclined manner, when it is raining, even though rainwater and the like flow on the main bottom piece of the inclined main frame member from a higher position to a lower position, due to the water barrier piece that is bent upward and formed at the inner side edge of the sub-bottom piece of the sub-frame member, rainwater and the like are dammed up and discharged downward from the inner side edge of the main bottom piece of the main frame member. Therefore, rainwater and the like are prevented from flowing onto the sub-bottom piece. Alternatively, since there is a gap into which water can flow between the sub-bottom piece of the sub-frame member and the main bottom piece of the main frame member, rainwater and the like flow into the gap into which this water can flow, and are discharged downward. Therefore, rainwater and the like are prevented from flowing onto the sub-bottom piece.
- Therefore, since the flow of rainwater and the like onto this sub-bottom piece is prevented, rainwater and the like do not flow into the internal space of the sub-wall portion. Accordingly, it is possible to avoid the sub-wall portion of the sub-frame member being damaged due to rainwater that has flowed into the internal space of the sub-wall portion freezing and expanding in volume. For that reason, if the solar cell module is installed in an inclined manner on an inclined place such as a roof, it is possible to prevent the module being damaged due to the freezing of rainwater and the like that have flowed into it.

- Next, solar cell modules according to Embodiments of the present invention are described with reference to the drawings. In the description of these embodiments, solar cell modules according to four types of embodiments, namely Embodiments 1 to 4, are described.
-
FIG. 1 is a partial perspective view showing the structure of asolar cell module 1 a according to Embodiment 1,FIG. 2 is a partial exploded perspective view thereof,FIG. 3 is a partial plan view thereof, andFIG. 4 is a cross-sectional view taken along A-A inFIG. 3 . Note that inFIGS. 1 , 3, and 4, asolar cell panel 9 is omitted, andFIGS. 1 and 2 show that thesolar cell module 1 a is inclined relative to ahorizontal surface 6 with aninclination angle 7. That is, thesolar cell module 1 a according to Embodiment 1 is installed in an inclined manner on an inclined place such as a roof, such that one of thesub-frame members 20 described later is in the lowest position. - The
solar cell module 1 a according to this Embodiment 1 has the following structure. That is, inFIGS. 1 to 4 , thesolar cell panel 9 has a rectangular shape, and using two pairs of members, each pair constituted from amain frame member 10 that holds one side of thissolar cell panel 9 and asub-frame member 20 that holds an adjoining side that adjoins this one side, thesolar cell panel 9 is held so as to be surrounded on the inner side. - The above-mentioned
main frame member 10 is constituted from a solar cell panel main holdingportion 11, amain wall portion 12, and amain bottom piece 16. Among these, the solar cell panel main holdingportion 11 has a U-shaped cross section, and inside the U shape, sandwiches one side of thesolar cell panel 9 from above and below, holding thesolar cell panel 9. Themain wall portion 12 is constituted from a mainouter wall 13 that is connected to the bottom of the solar cell panel main holdingportion 11 and extends downward therefrom. Themain bottom piece 16 is provided to the inner side of the lower edge of theMain wall portion 12, extending inward. - The
sub-frame member 20 is constituted from a solar cellpanel sub-holding portion 21, asub-wall portion 22, and asub-bottom piece 26. Among these, the solar cellpanel sub-holding portion 21 has a U-shaped cross section, and inside the U shape, sandwiches an adjoining side of thesolar cell panel 9 from above and below, holding thesolar cell panel 9. - The
sub-wall portion 22 is provided with asub-outer wall 23 and asub-inner wall 24 that extend downward with aninternal space 27 sandwiched therebetween, and asub-base piece 25 that closes theinternal space 27 at the lower edges of thesub-outer wall 23 and thesub-inner wall 24, provided under the solar cellpanel sub-holding portion 21, thesub-wall portion 22 being constituted with a side end opening of theinternal space 27 closed by abutting against the internal surface of themain wall portion 12 of themain frame member 10. Thesub-bottom piece 26 is provided to the inner side of the lower part of thesub-inner wall 24 of thesub-wall portion 22, extending inward. - With the above-described
solar cell module 1 a, as shown inFIG. 4 , thesub-bottom piece 26 of thesub-frame member 20 is positioned above themain bottom piece 16 of themain frame member 10, and the lower surface near the side end of thissub-bottom piece 26 abuts against the upper surface near the side end of themain bottom piece 16. Further, awater barrier piece 28 bent upward is formed at the inner side edge of thissub-bottom piece 26. - Accordingly, if the above-mentioned
solar cell module 1 a is installed in an inclined manner, when it is raining, even though rainwater and the like flow on themain bottom piece 16 of the inclinedmain frame member 10 from a higher position to a lower position, due to thewater barrier piece 28 that is bent upward and formed at the inner side edge of thesub-bottom piece 26 of thesub-frame member 20, as indicated by astream direction 8 shown inFIG. 1 , rainwater and the like are dammed up and discharged downward from the inner side edge of themain bottom piece 16 of themain frame member 10. Therefore, rainwater and the like are prevented from flowing onto the upper surface of thesub-bottom piece 26 of thesub-frame member 20. - Consequently, with the above-mentioned
solar cell module 1 a, as described above, the side end opening of theinternal space 27 of thesub-frame member 20 is closed by abutting against themain wall portion 12 of themain frame member 10 and, further, the flow of rainwater and the like onto the upper surface of thesub-bottom piece 26 of thesub-frame member 20 is prevented. Therefore, rainwater and the like do not flow into theinternal space 27 of thesub-wall portion 22 of thesub-frame member 20. Accordingly, it is possible to avoid thesub-wall portion 22 of thesub-frame member 20 being damaged due to rainwater that has flowed into theinternal space 27 of thissub-wall portion 22 freezing and expanding in volume. Therefore, if the above-describedsolar cell module 1 a is installed in an inclined manner on an inclined place such as a roof, it is possible to prevent the module being damaged due to the freezing of rainwater and the like that have flowed into it. - With the above-mentioned
solar cell module 1 a according to Embodiment 1, the angle formed by thewater barrier piece 28 and thesub-bottom piece 26 is 90 degrees as shown inFIG. 5 . However, the angle is not limited to this, and the angle formed by thewater barrier piece 28 and thesub-bottom piece 26 may be an angle between 90 degrees shown inFIGS. 5 and 120 degrees shown inFIG. 6 . As the angle formed by thewater barrier piece 28 and thesub-bottom piece 26, using 90 degrees to 120 degrees is superior compared with a case of using angles other than these, which has been confirmed in an experiment using a trial product. - Further, as shown in
FIG. 7 , it is preferable to form thewater barrier piece 28 such that the edge surface of thiswater barrier piece 28 is substantially parallel to thesub-bottom piece 26. By giving the end of thiswater barrier piece 28 such a shape, when rainwater and the like flow on themain bottom piece 16 of the inclinedmain frame member 10 from a higher position to a lower position, rainwater and the like are not easily allowed to climb over thiswater barrier piece 28. - Moreover, it is preferable to form the
water barrier piece 28 such that the height to the edge surface of thewater barrier piece 28 from the upper surface of thesub-bottom piece 26 is 2 mm or more. A favorable result can be obtained if the height to the edge surface of thewater barrier piece 28 from the upper surface of thesub-bottom piece 26 is made 2 mm or more, which has been confirmed in an experiment using a trial product. -
FIG. 8 is a partial perspective view showing the structure of asolar cell module 1 b according to Embodiment 2,FIG. 9 is a partial exploded perspective view thereof,FIG. 10 is a partial plan view thereof, andFIG. 11 is a cross-sectional view taken along B-B inFIG. 10 . Note that inFIGS. 8 , 10, and 11, asolar cell panel 9 is omitted, andFIGS. 8 and 9 show that thesolar cell module 1 b is inclined relative to ahorizontal surface 6 with aninclination angle 7. That is, thesolar cell module 1 b according to Embodiment 2 is installed in an inclined manner on an inclined place such as a roof, such that one of thesub-frame members 20 described later is in the lowest position, similar to thesolar cell module 1 a according to Embodiment 1. - The
solar cell module 1 b according to Embodiment 2 is almost the same as thesolar cell module 1 a according to Embodiment 1. Thesolar cell module 1 b according to Embodiment 2 differs from thesolar cell module 1 a according to Embodiment 1 in that, compared with thesolar cell module 1 a according to Embodiment 1 provided with themain wall portion 12 of themain frame member 10 formed only using the mainouter wall 13, thesolar cell module 1 b according to Embodiment 2 is provided with themain wall portion 12 of themain frame member 10 constituted from the mainouter wall 13, a main inner wall 14, and amain base piece 15, and furthermore aninternal space 17 formed therein. - Therefore, the
sub-frame member 20 of thesolar cell module 1 b in Embodiment 2 is completely the same as that of thesolar cell module 1 a in Embodiment 1, and provision of thewater barrier piece 28 to thesub-frame member 20 is similar to thesolar cell module 1 a according to Embodiment 1. - Accordingly, the function and effect provided to the
solar cell module 1 b according to Embodiment 2 are completely the same as the function and effect provided to thesolar cell module 1 a according to Embodiment 1. -
FIG. 12 is a partial perspective view showing the structure of asolar cell module 2 a according to Embodiment 3,FIG. 13 is a partial exploded perspective view thereof,FIG. 14 is a partial plan view thereof, andFIG. 15 is a cross-sectional view taken along C-C inFIG. 14 . Note that inFIGS. 12 , 14, and 15, asolar cell panel 9 is omitted, andFIGS. 12 and 13 show that thesolar cell module 2 a is inclined relative to ahorizontal surface 6 with aninclination angle 7. That is, thesolar cell module 2 a according to Embodiment 3 is installed in an inclined manner on an inclined place such as a roof, such that one of thesub-frame members 40 described later is in the lowest position. - The
solar cell module 2 a according to this Embodiment 3 has the following structure. That is, inFIGS. 12 to 15 , thesolar cell panel 9 has a rectangular shape, and using two pairs of members, each pair constituted from amain frame member 30 that holds one side of thissolar cell panel 9 and asub-frame member 40 that holds an adjoining side that adjoins this one side, thesolar cell panel 9 is held so as to be surrounded on the inner side. - The above-mentioned
main frame member 30 is constituted from a solar cell panel main holdingportion 31, amain wall portion 32, and amain bottom piece 36. Among these, the solar cell panel main holdingportion 31 has a U-shaped cross section, and inside the U shape, sandwiches one side of thesolar cell panel 9 from above and below, holding thesolar cell panel 9. Themain wall portion 32 is constituted from a mainouter wall 33 that is connected to the bottom of the solar cell panel main holdingportion 31 and extends downward therefrom. Themain bottom piece 36 is provided to the inner side of the lower edge of themain wall portion 32, extending inward. - The
sub-frame member 40 is constituted from a solar cellpanel sub-holding portion 41, asub-wall portion 42, and asub-bottom piece 46. Among these, the solar cellpanel sub-holding portion 41 has a U-shaped cross section, and inside the U shape, sandwiches an adjoining side of thesolar cell panel 9 from above and below so as to hold thesolar cell panel 9. - The
sub-wall portion 42 is provided with asub-outer wall 43 and asub-inner wall 44 that extend downward with aninternal space 47 sandwiched therebetween, and asub-base piece 45 that closes theinternal space 47 at the lower edges of thesub-outer wall 43 and thesub-inner wall 44, provided under the solar cellpanel sub-holding portion 41, thesub-wall portion 42 being constituted with a side end opening of theinternal space 47 closed by abutting against the internal surface of themain wall portion 32 of themain frame member 30. Thesub-bottom piece 46 is provided to the inner side of the lower part of thesub-inner wall 44 of thesub-wall portion 42, extending inward. - With the above-mentioned
solar cell module 2 a, as shown inFIG. 15 , thesub-bottom piece 46 of thesub-frame member 40 is positioned above themain bottom piece 36 of themain frame member 30, and agap 48 into which water can flow is formed between thesub-bottom piece 46 of thesub-frame member 40 and themain bottom piece 36 of themain frame member 30. - Accordingly, if the above-mentioned
solar cell module 2 a is installed in an inclined manner, when it is raining, even though rainwater and the like flow on themain bottom piece 36 of the inclinedmain frame member 30 from a higher position to a lower position, since thegap 48 into which water can flow is formed between thesub-bottom piece 46 of thesub-frame member 40 and themain bottom piece 36 of themain frame member 30, rainwater and the like flow into thegap 48 into which this water can flow, and are discharged downward as indicated by astream direction 8 shown inFIG. 12 . Therefore, rainwater and the like are prevented from flowing onto the upper surface of thesub-bottom piece 46. - Consequently, with the above-mentioned
solar cell module 2 a, as described above, the side end opening of theinternal space 47 of thesub-frame member 40 is closed by abutting against themain wall portion 32 of themain frame member 30 and, further, the flow of rainwater and the like onto the upper surface of thesub-bottom piece 46 of thesub-frame member 40 is prevented. Therefore, rainwater and the like do not flow into theinternal space 47 of thesub-wall portion 42. Accordingly, it is possible to avoid thesub-wall portion 42 of thesub-frame member 40 being damaged due to rainwater that has flowed into theinternal space 47 of thesub-wall portion 42 freezing and expanding in volume. Therefore, if the above-mentionedsolar cell module 2 a is installed in an inclined manner on an inclined place such as a roof, it is possible to prevent the module being damaged due to the freezing of rainwater and the like that have flowed into it. -
