The rear portion of the solar cell module is shown, and the front portion of the solar cell module is directed to the outside of the railing. The front part of the solar cell module is the part where sunlight is incident.

1 to 9, a support 10 for a solar cell module according to an embodiment of the present invention includes a bar member 100, a first bracket member 200) and a second bracket member (300).

The bar member 100 has a bar shape extending in one direction. The extending direction is indicated by II direction on the drawing. Direction corresponds to the height direction of the solar cell module 20.

A plurality of bar members 100 may be provided on the rear surface of the solar cell module 20. For example, as shown in FIG. 1, in order to stably install the solar cell module 20, two bar members 100 may be provided on the rear surface of the solar cell module, one on the left and one on the right. It is advantageous for stable fixing that the bar member supports the solar cell module in a symmetrical structure. Since the bar members 100 provided on the left and right sides of the solar cell module are symmetrical in the left and right direction, the following description will be made on the convenience of the first bar member 100 and the first bracket member 200 and the second bracket member 300, Will be mainly described.

1 to 3, the bar member 100 has a first end 102 and a second end 102 which are connected to a first edge 22 and a second edge 24 of the solar cell module 20, Respectively. For fastening, bolting can be utilized. For example, a hole for fastening is formed on the edges, and a hole having a concentric structure is formed on one end and the other end of the bar member, so that bolting through the holes can be performed.

The bar member 100 may be made of a steel material having a C shape. The material is not limited thereto, and may be aluminum or stainless steel which is resistant to corrosion in an external environment. When the 'C' shape is divided into the left and right flanges and the web between them, the bar member can be fastened to the solar cell module so that the web faces the solar cell module 20 in order to increase the support rigidity.

1 to 4, a first opening 103 for fastening with the first edge 22 is formed at one end 101 of the bar member 100 and a second opening 102 for fastening the other end 102 of the bar member 100, A second opening 104 for engagement with the second edge 24 is formed. Since bolting can be applied, it is preferable that the first opening 103 and the second opening 104 have a circular shape. At this time, as described later, the second opening 104 may have a long hole structure having a longer length in the II direction than the first opening 103. That is, when the length in the II direction of the first opening 103 is L1 and the length in the II direction of the second opening 104 is L2, L1 <L2 can be satisfied.

The bar member 100 may further include a third opening 105 adjacent to the second opening 104. The third opening 105 is located between the first opening 103 and the second opening 104. The third opening 105 serves as a fastening hole for fixing the first bracket member 200 to be described later to the bar member 100. Likewise, since the bolting can be applied, the third opening 105 can also have a circular shape.

The bar member 100 may further include a hole 106 for fixing a second bracket member 300 described later. As will be described later, the second bracket member 300 is rotatably connected through the hole 106 of the bar member 100 to support the solar cell module. A bolting method may also be applied to the hole 106, and the hole 106 may have a circular shape.

3 and 5, the first bracket member 200 is mounted to the first edge 22 of the solar cell module 20 together with the one end 101 of the bar member 100. As shown in FIG. Thus, the first bracket member 200 can be fixed to the bar member 100. The first rod 240 and the fastening member 250 may be further engaged to increase the fixing force between the first bracket member 200 and the bar member 100 as described later.

The first bracket member 200 is mounted on the first edge 22 of the solar cell module 20 together with the first end 101 of the bar member 100 to thereby connect the first end 101 of the bar member 100 and the railing Shown in Fig. 9, denoted by reference numerals 32, 34 and 36). Specifically, the first bracket member 200 connects one end 101 of the bar member and the upper bar 32 of the railing. The upper bar 32 extends in the direction III shown in the figure. This forms the upper support structure of the solar cell module 20. [

One first bracket member may be connected to each bar member, and therefore, as shown in FIG. 9, two first bracket members 200 may also be provided. The first bracket member also supports the solar cell module symmetrically to secure a stable upper support structure.

Referring to FIG. 5, the first bracket member 200 includes a first plate 210, a second plate 220, and a third plate 230 having a bending structure.

The first, second, and third plates 210, 220, and 230 may be integrally formed as interconnected components. Accordingly, the first bracket member 200 may have a single plate shape as a whole, and may have a three-step bent structure as shown in the figure. One bending between the first plate and the second plate, one bending at the second plate itself, and one bending between the second plate and the third plate.

The first bracket member 200 may be made of a steel material. It may be made of aluminum or stainless steel which is resistant to corrosion in an external environment.

The first plate 210 extends in one direction. The extending direction may be the same as the extending direction of the bar member.

A first hole (212) is formed in the first plate (210). The first hole 212 may have a circular shape corresponding to the first opening 103 of the bar member 100. The first plate 210 can be fastened to the first edge 22 of the solar cell module along with the first opening 103 of the bar member 100 through the first hole 212. Bolting can also be applied here.

7, when the bolt fastening member 110 passes through the first edge 22 of the solar cell module, the first opening 103 of the bar member, and the first hole 212 of the first plate, do. The bolt fastening member 110 may be composed of a bolt and a nut, and the bolt and the nut may be fastened to each other so that the solar cell module, the bar member, and the first plate can be fastened to each other. The bolt fastening member 110 may also be made of steel, aluminum, or stainless steel.

The first plate 210 may be disposed between the solar cell module 20 and the bar member 100 and fastened thereto. This further strengthens the upper fixed support structure by firmly securing the first bracket member, which is directly connected to the railing, between the solar cell module and the bar member.

The second plate 220 extends from the first plate 210 in a direction different from the extending direction of the first plate 210 and forms a first angle α with the first plate 210.

The second plate 220 has a bending structure. To this end, the second plate 220 may include a first sub-plate 222, a second sub-plate 224, and a bent portion 226.

Specifically, the first sub-plate 222 can extend in a direction (I direction) intersecting with the extending direction (II direction) of the first plate 210. Thus, the first plate and the first sub-plate form a first angle?. The first angle may be 90 [deg.], For example.

The second sub-plate 224 extends from the first sub-plate 222 in a direction different from the extending direction (I direction) of the first sub-plate 222. Thus, the first sub-plate and the second sub-plate form a second angle?. The second angle beta defines the bent portion 126. The second plate 220 has a bending structure by the bent portion 126. The second angle beta is greater than the first angle alpha. The second angle [beta] may be an obtuse angle greater than 90 [deg.] And less than 180 [deg.].

When installing a solar cell module on a railing, it is necessary to tilt the solar cell module to match the incident light in order to increase power generation efficiency. The summit altitude of each season considering the latitude (38 °) is about 52 ° for the equinox or the equinox, 75.5 ° for the bottom and 28.5 ° for the winter solstice. Therefore, it is necessary to tilt the solar cell module by 30 ~ 70 ° . In view of this, the second angle? May be an angle between 120 and 160 degrees. By having the second angle beta between 120 and 160 degrees, the photovoltaic power generation efficiency can be maximized.

When the solar cell module 20 is tilted as described above, the support 10 according to the embodiment of the present invention can provide a stable upper fixing structure through the bent portion 226 having the second angle. This will be described in more detail in Fig. 11 and Fig.

The second plate 220 has a bending structure surrounding the upper bar of the rail (see FIG. 9, reference numeral 32). The bending structure is defined by the bend 226. By having the second plate have a bending structure, the upper bar of the railing can be covered more efficiently. This further strengthens the upper fixed support structure by firmly securing the first bracket member, which is directly connected to the railing, to the railing. When the first bracket member is fixed to the railing, a separate tie member T may be involved.

The third plate 230 extends from the second plate 220 in the same direction as the extending direction II of the first plate 210.

A hole 232 is formed in the third plate 230. Corresponding to the hole 232, a hole 214 is also formed in the first plate 210. The hole 232 of the third plate and the hole 214 of the first plate serve as fasteners for fixing the first bracket member 200 to the bar member 100. Since bolting may be applied, the holes 232 and 214 may have a circular shape. The above-described third opening 105 is formed in the bar member 100 in correspondence with the holes 232 and 214.

Specifically, the first rod 240 passes through the hole 232 of the third plate, the hole 214 of the first plate, and the third opening 105 of the bar member. Both ends of the first rod 240 are fixed to the first plate 210 and the third plate 230, respectively.

To this end, the fastening member 250 is fastened to the first rod 240. For example, when the first rod 240 is a bolt, the nut 250 may be fastened to the other end of the first rod. When the first rod 240 has only a thread without a bolt head, the nut 250 can be fastened to both ends of the first rod.

The first bracket member 200 can be more firmly fixed to the bar member 100 by the first rod 240 and the fastening member 250 and this further assures a stable upper support structure of the support. For example, the first bracket member 200 structurally holds the possibility that the first bracket member 200 is separated from the upper bar (reference numeral 32 in FIG. 9) due to the self weight of the solar cell module 20 itself during installation. At this time, the first rod 240 and the fastening member 250 firmly fix the first bracket member 200 to the bar member 100, thereby preventing the first bracket member from being detached from the top bar. 7, the fixing structure between the first rod 240 and the fastening member 250 is formed by the outer surface of each of the first plate 210 and the third plate 230 The inner surface of the fastening member is in contact with the outer surface of the first plate and the inner surface of the other fastening member is in contact with the outer surface of the second plate) The distance d1 between the first plate 210 and the third plate 230 can be kept constant so as not to be distant from each other.

The first rod 240 and the fastening member 250 may be made of steel, aluminum, or stainless steel.

6 and 8, a second bracket member 300 according to an embodiment of the present invention is rotatably connected to the other end 102 of the bar member 100. As shown in FIG.

To this end, the second bracket member 300 includes a plate portion 310 rotatably connected to the other end 102 of the bar member. The plate portion 310 may be made of a steel material having a C shape. The material is not limited thereto, and may be aluminum or stainless steel which is resistant to corrosion in an external environment.

A hole 312 is formed in the plate 310 at one end. The hole 312 may have a circular shape corresponding to the hole 106 of the bar member 100 described above. The holes 312 and 106 may be bolted together for smooth rotation. 8, the bolt fastening member 120 passes through the hole 312 of the plate portion 310 and the hole 106 of the bar member 100, and the plate portion (not shown) 310 in a bolt and nut fastening manner. That is, the inner surface of the bolt fastening member 120 can be fastened to be in contact with the outer surface of the plate portion 310. The bolt fastening member 120 may be made of steel, aluminum, or stainless steel.

The plate portion 310 having the 'C' -shaped structure can be reduced in size during storage. Specifically, since the plate portion 310 is rotatably connected to the bar member 100, the size of the plate member 310 can be reduced by folding it toward the bar member 100 (in the direction R1). To this end, the 'C' shape of the plate portion may be arranged such that the concave portion faces the bar member. That is, when the plate portion is folded toward the bar member, the 'C' shape of the plate portion may be arranged so as to surround the bar member. In other words, when dividing the "C" shape of the plate portion into the left and right flanges and the web between them, the flange and the web wrap the outer surface of the bar member so that the plate portion can completely overlap the bar member.

As described above, since the bar member can also have a 'C' shape, according to the embodiment of the present invention, the plate portion and the bar member are arranged such that the concave portions of the ' .

A through hole 314 is formed in the plate portion 310 at the other end. And the second rod 320, which will be described later, passes through the through hole 314. The plate portion 310 is further provided with an opening 316 at the other end thereof. As will be described later, the second rod 320 is a portion that can be in direct contact with the vertical bars (refer to FIG. 9, indicated by reference numeral 36) of the railing so as to exclude interference between the plate portions and the vertical bars of the railing to be. When the "C" shape of the plate portion is divided into the left and right flanges and the web between them, the through holes 314 can be formed in the flanges, and the openings 316 can be formed in the web.

The second rod 320 passes the other end of the plate portion 310 through the through hole 314 in the direction III shown in the figure.

Upon installation of the support, the second rod 320 is directly fastened to the lower bar of the rail (refer to FIG. 9, denoted by 34). A separate tie member T may be involved for fastening. The lower bar 34 extends in the direction III shown in the figure.

The other end of the plate portion 310 is connected to the lower end bar of the rail so that the second bracket member 300 is connected to the other end 102 of the bar member 100 ) And the lower bar of the railing.

The other end 102 of the bar member may be spaced a certain distance from the lower end bar 24 of the rail by the length d2 of the plate portion 310 itself. At this time, the larger the separation distance, the larger the inclination of the installed solar cell module, and the smaller the separation distance, the smaller the inclination of the solar cell module. Meanwhile, as described above, the bending portion 226 of the first bracket member 200 has an angle of 120 to 160 degrees in consideration of the seasonal altitude of the southern part, so that the distance is interlocked with the angle of the bent portion. For example, when the bent portion has an angle of 120 degrees, the tilting of the solar cell module is small, and therefore, the lower end of the rail and the distance between the other ends of the bar can be made small. In this case, the length d2 of the plate portion 310 is preferably relatively short. On the contrary, when the bent portion has an angle of 160 °, the tilting of the solar cell module is also large, and thus the lower end of the rail and the distance between the other ends of the bar member can be formed to be large. In this case, the length d2 of the plate portion 310 is preferably relatively long.

8, a bolting member 130 is engaged to fasten the second edge 24 of the solar cell module and the other end 102 of the bar member 100 to each other.

The bolting member 130 penetrates the second edge 24 of the solar cell module and the second opening 104 of the bar member. The bolt fastening member 130 may be composed of a bolt and a nut, and the bolt and the nut may be fastened to each other so that the solar cell module and the bar member can be fastened to each other. The bolt fastening member 130 may have the same shape as the bolt fastening member 110 and may be made of steel, aluminum, or stainless steel.

The size of the solar cell module 20 may not be constant depending on the work tolerance. Therefore, a situation may arise in which the fastening holes have to be newly drilled when bolting one end and the other end of the bar member to both edges of the solar cell module. Therefore, in the fastening hole according to the embodiment of the present invention, a longer slot structure is applied in the longitudinal direction (II direction) of the bar member. Specifically, the second opening 104 of the present invention has a long hole structure having a longer length in the II direction than the first opening 103 (L1 <L2). Referring to FIG. 8, the length L2 of the second opening 104, which is fastened by the second edge 24 of the solar cell module and the bolt fastening member 130, is formed to be sufficiently long in the II direction. This flexibly copes with the size change due to the working tolerance of the solar cell module, so that it is possible to mount the support without newly drilling the fastening hole.

Since the first opening 103 is to be fastened not only to the solar cell module 20 and the bar member 100 but also to the first bracket member 200, It is advantageous in ease of installation. That is, the first opening 103 and the first hole 212 have a unified structure to focus on stable fixing to the bar member, and the second opening 104 has a long hole structure, Focus on flexible response.

Since one second bracket member can be connected to each bar member, two second bracket members 300 can be provided as shown in FIG. The second bracket member also supports the solar cell module symmetrically to secure a stable lower support structure.

Referring to FIG. 6, a thread S may be formed on the second rod 320 according to an embodiment of the present invention.

The second bracket member 300 according to an embodiment of the present invention includes a second rod member 300 that moves along the thread S of the second rod and adjusts the distance of penetration of the second rod 320 in the penetrating direction Adjustment nuts 330 may be further included.

Referring to FIG. 9, there are a plurality of vertical bars 36 connecting the upper bar 32 and the lower bar 34 to the railing. The plurality of vertical bars 36 are formed at regular intervals.

The second rod 320 can directly contact the vertical bars 36 to support the load of the solar cell module. In other words, the second rod 320 can be fastened to the lower end bar 34 while being in contact with the vertical bar 36. At this time, since the interval between the vertical bars 36 may vary from one installation environment to another, the second rod 320 may be moved laterally as needed to be fastened to the lower bar at a proper position. A more detailed description will be made with reference to FIG.

10 is a view showing a state where the second rod of the second bracket member is changed in the penetration distance by the distance adjusting nuts according to the embodiment of the present invention.

10, the penetration distance of the second rod 320 can be adjusted so that the center of the second rod 320 deviates from the center of the plate portion 310 in one direction. In Fig. 10, the penetration distance is adjusted so as to deviate toward the left direction. The distance adjusting nuts 330 move along the thread S and come into close contact with the plate portion 310 so that the second rod 320 can be firmly fixed to the plate portion 310 after the distance adjustment.

As described above, by adjusting the penetration distance of the second rod 320 in the II direction, two or more longitudinal bars can be brought into contact with the second rod. In FIG. 10, it is confirmed that the penetration distance is adjusted so that the second rod is deviated to the left, so that not only the vertical bar 36a but also the adjacent vertical bar 36b is contacted. This can further support the load of the solar cell module. And provides a fastening region through which additional rods can be fastened once again to the lower rod. Eventually the underlying support structure can be strengthened.

11 is a view showing in detail the connection state between the first bracket member and the railing upper bar according to the embodiment of the present invention.

12A and 12B are cross-sectional views illustrating a connection state between a first bracket member and a railing upper bar according to an embodiment of the present invention.

Referring to Figs. 11 and 12, as described above, the first bracket member 200 has a bending structure surrounding the upper bar 32 of the railing. The bending structure is defined by the bent portion 226 of the second plate 220.

The second angle beta of the bent portion 226 is formed to be larger than the first angle alpha between the first plate and the second plate to enable the inclined installation for increasing the photovoltaic efficiency of the solar cell module 20. [ And the first bracket member is further brought into close contact with the railing when tilted.

If the second angle is equal to or smaller than the first angle, the space between the first bracket member and the rail can be widened when the solar cell module is tilted. More specifically, the distance between the bent portion 226 and the upper bar 32 can be increased. Especially when the top bar has a square cross-sectional shape.

In contrast, the first bracket member according to the embodiment of the present invention has the bending structure described above, so that the bent portion 226 can be brought into close contact with the top bar 32 as much as possible. The distance between the bent portion 226 and the top bar 32 is indicated by d3 in Fig. 12B, when the upper bar 32 has a rectangular cross-sectional shape, the second sub-plate 226 of the second plate may be extended to a contact area a1 where the upper bar 32 contacts the upper bar 32 have. These structures make the upper support structure more robust.

As described above, the support for the solar cell module according to the embodiment of the present invention enables the solar cell module to be installed very easily and stably on the railing of a veranda or a terrace. In addition, it is possible to secure ease of installation by providing a support for a solar cell module standardized in a wide apartment housing installation environment. In addition, a heavy solar cell module is stably fixed in various installation environments. Also, it is very easy to re-install the components by changing the arrangement of the components by using only a bolting method without welding.
