Japanese Patent No. 2011-165895

By the way, in the structure which supports the edge part of each solar cell module which adjoins with a pressing tool from the upper side like patent document 1, the space for fixing a pressing tool to a mount frame is between these solar cell modules. It is necessary to provide each solar cell module.

However, such a space between the respective solar cell modules does not contribute to solar power generation at all, which causes a decrease in power generation efficiency of the solar power generation system.

For this reason, it is desirable to narrow the space between the solar cell modules. However, if the space is narrowed, the width of the presser becomes narrower, and it is necessary to reduce the size of bolts and nuts for fixing the presser. The support strength at the end of the solar cell module is reduced.

In particular, in an industrial photovoltaic power generation system, the area per solar cell module is large, the wind pressure applied to the solar cell module is large, and sufficient strength is required for the structure that supports the end of the solar cell module. However, since it is necessary to avoid a decrease in the strength, the space between the solar cell modules cannot be reduced, which is a cause of hindering the improvement of the power generation efficiency of the solar power generation system.

Therefore, the present invention has been made in view of the above-described conventional problems, and reduces the space between each solar cell module without reducing the strength of the structure that supports the end of the solar cell module. It is an object of the present invention to provide a solar cell module capable of increasing power generation efficiency, a solar cell module support structure, a solar cell module installation method, and a solar power generation system.

In order to solve the above problems, a solar cell module according to the present invention is connected to a solar cell panel and a back surface of the solar cell panel, and has a side shape that forms an opening portion on an end side of the solar cell panel. And a member.

For this reason, on the back surface side of the solar cell module, an operation for fixing the support member can be performed through the opening portion to fix the solar cell module. Therefore, even if the solar cell modules are arranged adjacent to each other and there is no space between the solar cell modules, the solar cell modules can be fixed, and the space between the solar cell modules can be reduced to generate power. Increase in efficiency can be achieved. In addition, on the back side of each solar cell module, there is no need to particularly restrict the size of the fixing structure for fixing the support member, the strength of the fixing structure can be sufficiently increased, and the area of the solar cell module can be increased. Even if the wind pressure received by the solar cell module is large, the support strength of the solar cell module will not be insufficient.

Moreover, in the solar cell module of the present invention, the support member is separated from the back surface of the solar cell panel at an end portion of the solar cell panel, and the solar cell panel inside the end portion of the solar cell panel. It is preferable that it is connected to the back surface of.

Thus, when the support member is separated from the back surface of the solar cell panel at the end portion of the solar cell panel, an opening portion is formed between the end portion of the solar cell panel and the support member.

For example, in the solar cell module of the present invention, the end portion of the support member is disposed at a position substantially equal to the end portion of the solar cell panel or an inner position of the solar cell panel, and from the back surface of the solar cell panel. It may be separated.

Thus, the end portion of the support member may be disposed at a position substantially equal to the end portion of the solar cell panel or an inner position of the solar cell panel, and may be separated from the back surface of the solar cell panel.

Moreover, in the solar cell module of the present invention, the solar cell module includes a plurality of the solar cell panels arranged, and the support member is bridged and fixed on the back surface of each solar cell panel. What connected the battery panel is preferable.

Thus, by connecting a plurality of solar cell panels with the support member, the configuration of the solar cell module can be simplified.

Next, the support structure of the solar cell module of the present invention includes a placement portion on which the end portion of the support member of the solar cell module of the present invention is placed, and an end portion of the support member as the placement portion. And a fixing member to be fixed.

In such a support structure of the solar cell module of the present invention, the support member is passed through the opening portion between the support member and the back surface of the solar cell panel in a state where the adjacent solar cell modules are arranged adjacent to each other with almost no gap. Each solar cell module can be fixed by performing an operation for fixing the end portion of the solar cell module to the mounting portion by the fixing member. For this reason, the space between each solar cell module can be reduced and the power generation efficiency can be increased. Further, on the back side of each solar cell module, there is no need to particularly restrict the size of the fixing member and the mounting portion, and the strength of the fixing member and the mounting portion can be sufficiently increased. There is no shortage of support strength.

Each solar cell module can be fixed by performing an operation for fixing the end portion of the solar cell module to the mounting portion by the fixing member. For this reason, the space between each solar cell module can be reduced and the power generation efficiency can be increased. Further, on the back side of each solar cell module, there is no need to particularly restrict the size of the fixing member and the mounting portion, and the strength of the fixing member and the mounting portion can be sufficiently increased. There is no shortage of support strength.

Next, the photovoltaic power generation system of the present invention uses the support structure for the solar cell module of the present invention.

In the present invention, the support member is connected to the back surface of the solar cell panel and has a side surface shape that forms an opening portion on the end side of the solar cell panel. For this reason, on the back surface side of the solar cell module, an operation for fixing the support member can be performed through the opening portion to fix the solar cell module. Therefore, even if the solar cell modules are arranged adjacent to each other and there is no space between the solar cell modules, the solar cell modules can be fixed, and the space between the solar cell modules can be reduced to generate power. Increase in efficiency can be achieved. In addition, on the back side of each solar cell module, there is no need to particularly restrict the size of the fixing structure for fixing the support member, the strength of the fixing structure can be sufficiently increased, and the area of the solar cell module can be increased.

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

FIG. 1 is a perspective view showing a solar power generation system to which an embodiment of a support structure for a solar cell module of the present invention is applied. 2 and 3 are a front view and a rear view showing the solar power generation system, and FIG. 4 is a side view showing the solar power generation system.

As shown in FIGS. 1 to 4, in the photovoltaic power generation system, a plurality of bases 11 are arranged on the ground at equal intervals and in parallel, and a plurality of solar cell modules 12 are bridged on the mounting inclined surface 11e of each base 11. The solar cell modules 12 are arranged in two upper and lower rows.

In the lower row, the ends of the two connection support bars 14 of the solar cell module 12 are fitted into the two front grooves 13 of the mounting inclined surface 11e of the base 11, and in the upper row, the solar cell module. 12 end portions of the two connection support bars 14 are fitted into the two rear grooves 13 on the mounting inclined surface 11 e of the base 11.

The ends of the connection support bars 14 of the solar cell modules 12 adjacent to each other on the left and right are abutted against each other by the groove 13 of the mounting inclined surface 11e and are fixed by one fixing tool 15.

1 to 4, the direction parallel to the row of bases 11 is defined as the X direction (left-right direction), and the direction orthogonal to the X direction is defined as the Y direction (front-rear direction).

5 and 6 are a perspective view and a side view showing the solar cell module 12. As shown in FIGS. 5 and 6, the solar cell module 12 includes three solar cell panels 16 and two connection support bars 14, and two solar cell modules 16 are provided on the back surface of each solar cell panel 16. The connection support bar 14 is bonded and fixed.

The solar cell panel 16 has a rectangular flat plate shape. For example, a solar cell formed by sequentially laminating a transparent electrode film, a photoelectric conversion layer (semiconductor layer), and a back electrode film between two glass plates is sandwiched. Thus, the end of each glass plate is sealed. The solar cell panel 16 will be described in more detail. A transparent electrode, a photoelectric conversion layer made of a semiconductor layer, and a back electrode layer are laminated in this order on a glass substrate that is a light-transmitting substrate, and a solar cell is formed. The transparent glass substrate which is a protective plate is bonded to the back electrode layer side, and the space between the glass substrates is sealed. For example, a tempered glass having a thickness of about 2 mm is applied as the glass plate, and a crystalline material is applied as the semiconductor layer.

7 and 8 are a perspective view and a cross-sectional view showing the connection support bar 14. As shown in FIGS. 7 and 8, the connection support bar 14 is bent inward at one side of the long main plate 14a, each side plate 14b bent at both sides of the main plate 14a, and further bent upward. Each of the folded reinforcing portions 14c has a substantially U-shaped cross section. The main plate 14a is formed with a recess 14d for increasing the rigidity of the connection support bar 14.

Further, as shown in FIG. 7, at both ends of the connection support bar 14, a notch portion 14e is formed by notching the end portion of the main plate 14a and the upper end portion of each side plate 14b. The lower side of the end portion of the side plate 14b and the end portion of each folded reinforcing portion 14c serve as a connecting portion 14f.

Such a connection support bar 14 is obtained by punching and bending a steel plate and plating the surface thereof.

Here, as shown in FIG. 5, the three solar cell panels 16 are arranged side by side, the boundary of each solar cell panel 16 and the two connection support bars 14 are orthogonal, and each connection support bar 14 is fixed. In this state, the main plate 14a of each connection support bar 14 is overlaid on the back surface (glass surface) of each solar cell panel 16 via an adhesive, and each connection support bar 14 is connected to each other. Each solar cell panel 16 is integrally connected and supported by each connection support bar 14 by being adhered to the back surface of the solar cell panel 16. A slight gap may be provided between the solar cell panels 16 or the solar cell panels 16 may be brought into contact with each other.

Each connection support bar 14 has the same length as the length from one end to the other end of each solar cell panel 16 (lateral width of the solar cell module 12), and extends over substantially the entire width of each solar cell panel 16. The adhesion area to each solar cell panel 16 is increased by bonding. Further, in the longitudinal direction of each connection support bar 14, both end positions of each connection support bar 14 coincide with both end positions of the solar cell module 12.

Further, each connecting support bar 14 is improved in bending strength by a U-shaped cross-sectional shape. For this reason, each solar cell panel 16 is firmly supported by each connection support bar 14.

Furthermore, each connection support bar 14 is arranged at a position substantially 1/4 of the vertical width of each solar cell panel 16. Thereby, each solar cell panel 16 is supported on each connection support bar 14 with good balance.

Further, as shown in FIGS. 1 to 4, each connection support bar 14 is spanned on the mounting inclined surface 11e of each base 11 and supports each solar cell module 12, so that the base of the photovoltaic power generation system is supported. Serves as a component. Therefore, each connection support bar 14 performs both the function of connecting and supporting the three solar battery panels 16 and the function as a component of the frame of the solar power generation system.

Such a solar cell module 12 does not include a rectangular metal frame for protecting the end portion of the solar cell module 12, and the peripheral edge portions of the translucent substrate (glass plate) and the protective plate (glass plate) are exposed. This is a so-called frameless type solar cell module.

FIG. 9 is an enlarged side view showing the solar cell module 12 when viewed from the direction orthogonal to the connection support bars 14. As shown in FIG. 9, the connection portion 14 f of the connection support bar 14 is separated from the back surface of the solar cell panel 16 at the end portion of the solar cell panel 16, and the cutout portion 14 e of the connection support bar 14 is the back surface of the solar cell panel 16. An opening portion S that is open in a direction along one side of the end portion of the solar cell module 12 that is orthogonal to each connection support bar 14 is formed between the connection portion 14f and the connection portion 14f. The main plate 14 a of the connection support bar 14 is bonded to the back surface of the solar cell panel 16 on the inner side (inner side than the opening part S) of the end portion of the solar cell panel 16.

As shown in FIG. 10, between the adjacent solar cell modules 12, the respective opening portions S are continuous to form a wider opening portion.

FIG. 11 is a perspective view showing the base 11. As shown in FIG. 11, the base 11 is made of concrete and has a trapezoidal shape when viewed from the side. The base 11a is placed on the ground, the top 11b is inclined with respect to the ground, and the two sides.

Sides

11c and 11d are provided. The upper surface of the upper side portion 11b is a mounting inclined surface 11e. The mounting inclined surface 11e is inclined in the Y direction, and the front end of the mounting inclined surface 11e is lower than the rear end.

Further, as shown in FIG. 11, four grooves 13 extending along the X direction are formed on the mounting inclined surface 11e of the base 11 so as to be separated from each other in the Y direction. Each groove 13 is generally U-shaped in cross section and has a rectangular bottom surface 13a. In the Y direction, the bottom surface 13a of each groove 13 is inclined at the same angle as the mounting inclined surface 11e, and the front end of the bottom surface 13a is lower than the rear end. In the X direction, the bottom surface 13a of each groove 13 is not inclined.

Furthermore, each anchor bolt 17 perpendicular to each bottom surface 13a is projected from the bottom surface 13a of each groove 13.

FIG. 12 is a perspective view showing the fixture 15. As shown in FIG. 12, the fixture 15 includes a bottom plate 15a, reinforcing pieces 15b bent upward at two opposing sides of the bottom plate 15a, and each of the reinforcing plates 15b bent obliquely upward and outward at the other two opposing sides of the bottom plate 15a. It has the inclination board 15c and each side board 15d bent below by the upper edge of each inclination board 15c. The bottom plate 15a is formed with a long hole 15e, and the lower end 15f of each side plate 15d is formed in a saw blade shape.

Such a fixture 15 is obtained by punching and bending a steel plate and plating the surface thereof.

FIGS. 13 and 14 are a cross-sectional view and a vertical cross-sectional view showing a support structure in which the connection portion 14f of the connection support bar 14 of each adjacent solar cell module 12 is abutted and supported in the groove 13 of the mounting inclined surface 11e of the base 11. It is. As shown in FIGS. 13 and 14, a spacer 18 is disposed on the bottom surface 13 a of the groove 13 of the base 11, and on this spacer 18, the connecting portion 14 f (each side plate) of the connection support bar 14 of each adjacent solar cell module 12. 14b and the end portions of the folded reinforcement portions 14c are placed and abutted on each other, and the connection portions 14f of the connection support bars 14 are arranged on both sides of the anchor bolts 17 together. Then, the anchor bolt 17 is passed through the perforation 15e of the bottom plate 15a of the fixture 15, the bottom plate 15a of the fixture 15 is placed on the spacer 18, and the fixture 15 presses the connection portion 14f of each connection support bar 14 together. Each side plate 15d of the fixture 15 is sandwiched inside the side plate 14b of each connection support bar 14, and the saw blade-like lower end 15f of each side plate 15d is inside the folded reinforcement portion 14c of each connection support bar 14. In contact with the bottom surface, each inclined plate 15 c of the fixture 15 is in contact with the upper end of the folded reinforcing portion 14 c of each connection support bar 14.

Moreover, each connection support bar 14 has the same length as the width of the solar cell module 12, and both end positions of each connection support bar 14 and both end positions of the solar cell module 12 are in the longitudinal direction of each connection support bar 14. Therefore, when the connection portions 14f of the connection support bars 14 of the adjacent solar cell modules 12 are brought into contact with each other, the solar cell panels 16 of the adjacent solar cell modules 12 are adjacent to each other with almost no gap. Therefore, there is almost no empty space between solar cell modules that does not contribute to solar power generation.

In this state, the nut 19 is screwed into the anchor bolt 17, the nut 19 is tightened, and the connection portion 14f of each connection support bar 14 is between the bottom surface 13a of the groove 13 of the base 11 and each side plate 15d of the fixture 15. It is pinched and fixed. At this time, the saw blade-like lower end 15f of each side plate 15d of the fixture 15 is pressed into the inner bottom surface of the folded reinforcing portion 14c of each connection support bar 14, and each connection support bar 14 is firmly fixed and adjacent. Each solar cell module 12 is also firmly fixed.

The nut 19 is attached and tightened by passing a tool such as the nut 19 and a ratchet wrench through the opening S between the back surface of the solar cell panel 16 and the connection portion 14f of the connection support bar 14 shown in FIGS. The nut 19 can be screwed into the anchor bolt 17 and the nut 19 can be tightened with a ratchet wrench.

Here, the bottom surface 13a of the groove 13 of the base 11 is inclined at the same angle as the mounting inclined surface 11e of the base 11 in the Y direction, and is not inclined in the X direction. Therefore, as shown in FIGS. 13 and 14, in a state where the connection portion 14f of the connection support bar 14 is sandwiched and fixed between the bottom surface 13a of the groove 13 of the base 11 and the fixing tool 15, as shown in FIGS. As shown, the main plate 14a of the connection support bar 14 is inclined at the same angle as the mounting inclined surface 11e of the base 11 in the Y direction, and the light receiving surface of the solar cell module 12 parallel to the main plate 14a of the connection support bar 14 is the same. Inclined at an angle and generally facing the sun. In the X direction, the main plate 14a of the connection support bar 14 is supported horizontally, and the end of the solar cell module 12 in the X direction is held horizontally.

Next, a method for installing such a solar cell module will be described with reference to FIGS.

First, as shown in FIG. 15, a plurality of bases 11 are arranged on the ground with the same pitch as the horizontal width of the solar cell module 12 in parallel. At this time, the direction (X direction) of the rows of the bases 11 is directed in the east-west direction, and the direction (Y direction) perpendicular to the rows of the bases 11 is directed in the north-south direction.

On the other hand, as shown in FIG. 5, the three solar cell panels 16 are arranged side by side, and each connection support bar 14 is bonded to the back surface of each solar cell panel 16 to assemble the solar cell module 12. The assembling work of the solar cell module 12 is preferably performed at the installation site of the gantry and the solar cell module 12. This is because each connection support bar 14 protrudes from the back surface side of the solar cell module 12, and therefore, when a large number of solar cell modules 12 are stacked, the volume becomes too large to be transported. On the other hand, since the solar cell panel 16 has a rectangular flat plate shape, even if a large number of solar cell panels 16 are stacked, the volume does not become too large. Moreover, since the connection support bar 14 is a rod-shaped thing, if many things are bundled, the volume can be stored small. For this reason, it is preferable that the solar cell panel 16 and the connection support bar 14 are separately transported and the solar cell module 12 is assembled at the installation site of the gantry.

Next, a plurality of solar cell modules 12 are sequentially installed over the mounting inclined surface 11e of each base 11. At this time, a spacer 18 is arranged on the bottom surface 13a of the groove 13 of the base 11 as shown in FIGS. 13 and 14 for each groove 13 of the base 11, and the adjacent solar cell modules 12 as shown in FIG. The connecting portion 14f of the connection support bar 14 is fitted into the groove 13 of the base 11, and the anchor bolts 17 are inserted through the perforations 15e of the bottom plate 15a of the fixture as shown in FIG. It is arranged over the connecting portion 14f of each connection support bar 14.

The fixing tool 15 may be disposed on the connection portion 14f of each connection support bar 14 through the opening portion S between the back surface of the solar cell panel 16 and the connection portion 14f of the connection support bar 14 shown in FIGS. it can. Alternatively, one of the connection support bars 14 is moved in the groove 13 of the base 11 so as to be separated from the other, the space between the adjacent solar cell modules 12 is opened, and the fixture 15 is connected to each connection support bar 14 through the space therebetween. Then, one connection support bar 14 is moved along the groove 13 of the base 11, the connection portions 14 f of each connection support bar 14 are abutted, and the adjacent solar cell modules 12 are connected to each other. You may approach or adjoin.

Thereafter, a nut 19 is screwed into the anchor bolt 17 through an opening portion S between the back surface of the solar cell panel 16 and the connection portion 14f of the connection support bar 14 shown in FIGS. 9 and 10, and the nut is tightened with a tool such as a ratchet wrench. 19 is tightened, and the connecting portion 14f of the connection support bar 14 of each adjacent solar cell module 12 is sandwiched and fixed between the bottom surface 13a of the groove 13 of the base 11 and each side plate 15d of the fixture 15. As a result, the saw blade-like lower end 15f of each side plate 15d of the fixture 15 is pressed into the inner bottom surface of the folded reinforcing portion 14c of each connection support bar 14, and each connection support bar 14 is firmly fixed and adjacent. Each solar cell module 12 is also firmly fixed.

As described above, in the installation method of the solar cell module 12 of the present embodiment, the adjacent solar cell modules 12 are arranged adjacent to each other with almost no gap, so that the power generation efficiency can be increased. In addition, in the state where the adjacent solar cell modules 12 are adjacent to each other with almost no gap, the connection support bars 14 are connected through the opening portions S between the back surface of the solar cell panels 16 and the connection portions 14 f of the connection support bars 14. The fixing part 14f can be fixed. Further, on the back side of each solar cell module 12, there are no particular restrictions on the size of the mounting inclined surface 11e of the base 11, the size of the connecting portion 14f of the connection support bar 14, and the thickness of the steel plate, and the anchor bolt 17 and the nut. The size of 19 is not particularly limited, and the fixing strength of the connection portion 14f of each connection support bar 14 can be sufficiently increased. Therefore, the solar cell module 12 is formed by connecting the three solar cell panels 16 with the two connection support bars 14, and the area of the solar cell module 12 is large and the wind pressure received by the solar cell module 12 is large. However, the supporting strength of the solar cell module 12 will not be insufficient.

In addition, the solar cell module 12 has a simple structure in which three solar cell panels 16 are connected by two connection support bars 14, and the support structure of each connection support bar 14 of the solar cell module 12 is connected to each base 11. Because of the simple structure of being mounted and fixed on the mounting inclined surface 11e, the number of parts and the cost can be greatly reduced.

18 (a) and 18 (b) are a perspective view showing a modification of the solar cell module partially enlarged and a longitudinal sectional view showing a support structure of the solar cell module. In the solar cell module 12A of this modified example, the end portion of each side plate 14b of the connection support bar 14A is cut out to form a cutout portion 14g, and the end portion of the main plate 14a is left uncut to leave the main plate 14a as the sun. It extends to the end of the battery panel 16 and adheres, and further, the lower end of each side plate 14b and the end of each folded reinforcing portion 14c are left uncut to form a connection portion 14f. The connection portions 14f of the connection support bars 14A are abutted, and the connection portions 14f of the connection support bars 14A are pressed and fixed together by the fixture 15.
