Hereinafter, the embodiment according to Fig. 1 will be referred to as a first embodiment, and the embodiment according to Figs. 2 to 5 will be referred to as a second embodiment. The first embodiment and the second embodiment commonly include the sound-absorbing unit 10, the front plate 40, the solar cell module unit 20, and the support frame unit 50. In the first embodiment, The plate 130 and the rear ventilation plate 30 in the second embodiment have some differences and correspond to each other. 5, a rear plate 130 as shown in FIG. 1 is provided on a rear surface of the sound-absorbing unit 10, and a solar cell module (not shown) is mounted on the rear plate 130. In this embodiment, The unit 20 and the rear ventilation plate 30 may be formed to be inclined. In this case, the configuration of the back plate 130 becomes common to both the first embodiment and the second embodiment.

A common main feature of the first embodiment and the second embodiment is that the solar cell module unit 20 is disposed obliquely to a direction perpendicular to the rear side of the sound-absorbing unit 10 (vertical mounting direction of the sound-absorbing panel). A common main feature is that the support frame unit 50 is provided with ventilation holes 130b and 51a to be ventilated with the rear space (refer to reference character S in Figs. 6A and 6B) of the solar cell module unit 20. [ Thus, the air that has cooled the solar cells 21 in the rear space S of the solar cell module unit 20 can escape to the outside through the vent holes 130b and 51a.

[First embodiment of sound-absorbing panel]

Hereinafter, a sound-absorbing panel having a solar cell according to a first embodiment will be described. Referring to Figure 1, a sound-absorbing panel having a solar cell includes a sound-absorbing unit (see reference numeral 10 in Figure 5), a front plate (see reference numeral 40 in Figure 5), a back plate 130, a solar cell module unit 20 And a support frame unit (50). Since the sound-absorbing unit and the front plate in the first embodiment are the same as the sound-absorbing unit 10 and the front plate 40 in the second embodiment, the description thereof will be omitted. Reference is made to the description and reference numerals in the drawings. At this time, the sound-absorbing unit 10 is formed in a panel shape. The front plate (40) is disposed on the front side of the sound absorption unit (10). At this time, the front side is a direction in which a sound source such as noise is generated. On the other hand, the rear side may be a substantially southward or southward-facing direction. At this time, the front plate 40 has a plurality of sound-absorbing holes 40a communicating with the sound-absorbing unit 10. The rear plate 130 is disposed on the rear side of the sound-absorbing unit 10. Next, the solar cell module unit 20 has a plurality of solar cells 21. The solar cell module unit 20 is disposed at the first angle with respect to the vertical direction and with the rear plate 130 and the obliquely rear side. The support frame unit 50 supports the sound absorption unit 10, the front plate 40, the rear plate 130, and the solar cell module unit 20. At this time, the support frame unit 50 forms the vent hole 130b to ventilate the rear space S of the solar cell module unit 20, and supports the solar cell module unit 20 in an inclined manner.

Here, in one example, the first angle may range from 5 to 15 degrees. When the solar cell module unit 20 faces the south-east and the first angle is 15 °, solar light is incident almost perpendicularly to the solar cell module unit 20 in the vicinity of about 37 degrees latitude and about 12:30 half-day. However, when the first angle is more than 15 degrees, the upper end of the solar cell module unit 20 protrudes from the top of the solar cell module unit 20 of the lower sound-absorbing panel when the sound-absorbing panel is installed, The length of the solar cell module unit 20 in the oblique direction is significantly reduced. Even when the first angle is less than 5 [deg.], It is difficult to expect an effective improvement of the photovoltaic power generation efficiency as compared with the case where the solar cell module unit 20 is vertically installed.

In addition, the ratio of the oblique direction length of the solar cell module unit 20 to the vertical length of the rear plate 130 may range from 0.52 to 0.85. For example, when the first angle is 15 degrees, the ratio of the oblique direction length of the solar cell module unit 20 to the vertical length of the rear plate 130 may be approximately 0.52. At this time, when the ratio of the length of the solar cell module unit 20 in the vertical direction to the length of the rear plate 130 is larger than 0.52, when the sunlight is incident in the vicinity of latitude 37 degrees, The lower end portion of the solar cell module unit 20 protrudes shadows of the upper portion of the solar cell module unit 20 of the lower sound-absorbing panel when the sound-absorbing panel is installed. If the ratio of the length of the solar cell module unit 20 in the vertical direction to the length of the rear plate 130 in the vertical direction is made small, the area of the solar cell module unit 20 is extremely reduced, it's difficult. In addition, the ratio of the oblique direction length of the solar cell module unit 20 to the vertical length of the rear plate 130 when the first angle is 5 ° may be approximately 0.85. At this time, if the ratio of the length of the solar cell module unit 20 in the vertical direction to the length of the rear plate 130 is larger than 0.85, when sunlight is incident in the vicinity of latitude 37 degrees, The lower end portion of the solar cell module unit 20 protrudes shadows of the upper portion of the solar cell module unit 20 of the lower sound-absorbing panel when the sound-absorbing panel is installed. Accordingly, when the embodiment is implemented by gradually deforming the first angle from 5 DEG to 15 DEG, the ratio of the oblique direction length of the solar cell module unit 20 to the vertical length of the rear plate 130 is approximately 0.85 to 0.52 To reduce the size of the display area.

The ventilation hole 130b is formed in a side ventilation hole 130a formed by opening the upper portion of the upper portion of the solar cell module unit 20 and the upper side frame 51 of the support frame unit 50, (130b). For example, although only the side ventilation holes 130b are illustrated in FIG. 1 as the ventilation holes 130b, ventilation openings such as the upper ventilation holes 51a may be formed on the upper side frame 51 as shown in FIGS. have. For example, although not shown, the side vent holes 130b of FIG. 1 and the upper vent holes 51a of FIGS. 2 to 5 may be provided to form the vent holes. At this time, the air introduced from the lower side (opened in FIG. 1) of the solar cell module unit 20 is cooled and heated by the solar cell 21 on the back side of the solar cell module unit 20, ). &Lt; / RTI &gt;
For example, the upper end portion of the solar cell module unit 20 may be spaced apart from the rear surface of the sound-absorbing unit 10. Although not shown in FIG. 1, the vent holes are formed in a plurality of upper ventilation holes (see reference numeral 51a in FIGS. 2 to 5) formed in the upper side frame of the support frame unit 50 connected to the upper end of the solar cell module unit 20, . &Lt; / RTI &gt; The upper ventilation hole may be formed in the upper part of the rear space so as to communicate with the rear space formed between the back surface of the solar cell module unit 20 and the rear surface of the sound absorption unit 10 in a vertical direction. The air introduced from the lower part of the inclined solar cell module unit 20 is cooled by the cooling of the solar cell on the back surface of the solar cell module unit 20 and is discharged through the upper ventilation hole 51a, Lt; / RTI &gt;

6A to 6B in the second embodiment, similar to the embodiment in the second embodiment, the front plate 40 includes a plurality of sound absorbing hole covers (not shown in Fig. 1) 41). At this time, one side of the sound-absorbing hole cover 41 is connected to the periphery of the sound-absorbing hole 40a and the other side is spaced apart from the sound-absorbing hole 40a to cover the sound-absorbing hole 40a.

Further, in one example, in the embodiment of the first embodiment, the support frame unit 50 includes an upper frame 51, a slant support frame 53, a lower frame (see reference numeral 55 in Fig. 5) And may include a frame 57. The upper frame 51 is connected to the upper end of the front plate 40 and the rear plate 130 and the lower frame 55 is connected to the front plate 40 and the rear plate 130). The insertion support frame 57 is connected to the side ends of the front plate 40 and the rear plate 130 and is fitted into the groove of the support frame 200 when the sound-absorbing panel is installed, for example, referring to FIG. Although the sound-absorbing panel 100 shown in FIG. 7 shows the sound-absorbing panel 100 according to the second embodiment, the sound-absorbing panels shown in FIG. 1 can also be fitted into the grooves of the frame 200 Do. In addition, the inclined support frame 53 is coupled to the side end of the solar cell module unit 20 to support the solar cell module unit 20 in an inclined manner. 1, one end of the inclined support frame 53 may be coupled to the side end of the solar cell module unit 20, and the other end may be coupled to the rear plate 130 or the insertion support frame 57. Accordingly, the insertion support frame 57 protrudes laterally from the inclined support frame 53 and is fitted into the groove of the support frame 200 when the sound-absorbing panel is installed, referring to FIG.

For example, although not shown, the rear plate 130 may have a concave-convex structure having a vertical cross-sectional structure in order to adjust a reflection angle of a sound wave entering into a sound-absorbing space. At this time, the intervals and the inclination of the concavities and convexities can be adjusted so that the sound waves coming in through the sound-absorbing holes 40a of the front plate 40 are not reflected through the sound-absorbing holes 40a after being reflected on the rear plate 130. [ The rear plate 130 may be made of the same material as the front plate 40 or may be made of another material.

5), a front plate (refer to reference numeral 40 in FIG. 5), a solar cell module unit 20 and a support frame unit 50 (refer to reference numeral 40 in FIG. 5) of a sound-absorbing panel having a solar cell according to the first embodiment Is also provided in the sound-absorbing panel 100 according to the second embodiment described later, it can be understood with reference to the description of the embodiments of the second embodiment, except for the case where it is not implemented as the first embodiment. Therefore, in the examples according to the second embodiment among the specific descriptions of the sound-absorbing unit 10, the front plate 40, the solar cell module unit 20 and the support frame unit 50 of the sound-absorbing panel according to the first embodiment Will be omitted, and the following description will be referred to.

At this time, the sound-absorbing panel according to the second embodiment includes the sound-absorbing unit 10, the front plate 40, the solar cell module unit 20, the rear ventilation plate 30 and the support frame unit 50. The sound-absorbing unit 10 is formed in a panel shape. The front plate (40) is disposed on the front side of the sound absorption unit (10). At this time, the front plate 40 has a plurality of sound-absorbing holes 40a communicating with the sound-absorbing unit 10. Next, the solar cell module unit 20 has a plurality of solar cells 21. The solar cell module unit 20 is disposed at an inclined angle at a first angle with respect to the vertical direction on the back side of the sound- The rear ventilation plate 30 has a plurality of lower ventilation holes 30a. The rear ventilation plate 30 is disposed on the lower side of the solar cell module unit 20 on the rear side of the sound absorption unit 10. At this time, the upper end portion of the rear ventilation plate 30 is engaged with the lower end portion of the solar cell module unit 20, and the lower end portion is inclined at a second angle with respect to the vertical direction. The support frame unit 50 supports the sound absorption unit 10, the front plate 40, the solar cell module unit 20, and the rear ventilation plate 30. At this time, the support frame unit 50 forms a ventilation hole 51a to ventilate the backside space S of the solar cell module unit 20, and supports the solar cell module unit 20 in an inclined manner.

For example, although not shown, the rear plate 130 shown in FIG. 1, which is a sound-absorbing panel according to the embodiment of the first embodiment, may be further included in the sound-absorbing panel according to the embodiment of the second embodiment. At this time, the solar cell module unit 20 and the rear ventilation plate 30 may be disposed on the rear plate 130. A detailed description of the back plate 130 in this embodiment will be made with reference to the embodiment of the first embodiment described above.

For example, when a sound-absorbing panel having a solar cell according to an embodiment of the present invention is installed as shown in FIG. 7, when the front plate 40 of the sound-absorbing panel 100 is installed on the road side, And the solar cell module unit 20 may be installed so as to face toward the south or toward the south.

Through one example of the present invention, it is possible to obtain environmentally friendly electricity through solar power generation while attaining the soundproof effect which is the original purpose of the sound-absorbing panel. Accordingly, it is possible to supply the obtained electricity to an electric facility such as a street lamp or a traffic light, so that it is possible to reduce the cost of bringing in electric power and electric facilities.

Referring to the drawings, each configuration will be described in more detail.

Sound absorption unit (10)

5, 6A and / or 6B, the sound-absorbing unit 10 absorbs and attenuates noise and the like. The sound-absorbing unit 10 is made of a sound-absorbing material in the form of a panel. The material of the sound-absorbing material may be a material used in the technical field related to a sound-absorbing or sound-insulating panel or a sound-absorbing or sound-insulating wall. The material of the sound absorbing material may be a known material as well as a known material. Since the material of the sound-absorbing material is well known in the art, a detailed description thereof will be omitted.

Referring to FIG. 5, the sound-absorbing unit 10 is supported by the support frame unit 50. At this time, the sound-absorbing unit 10 is disposed in the inner space surrounded by the front plate 40, the solar cell module unit 20, the rear ventilation plate 30, and the support frame unit 50 that supports the front plate 40,

6A and 6B, a rear space S is formed between the rear surface of the sound-absorbing unit 10 and the solar cell module unit 20 to be described later, and the air introduced into the rear space S Thereby cooling the solar cell 21 on the back side of the solar cell module unit 20 described later.

For example, although not shown, in one embodiment, the rear plate 130 in the sound-absorbing panel according to the first embodiment may be additionally disposed on the rear side of the sound-absorbing unit 10. At this time, the solar cell module unit 20 and the rear ventilation plate 30 are disposed on the rear plate 130 in an inclined manner.

The front plate (40)

5, 6A and / or 6B, the front plate 40 has a plurality of sound-absorbing holes 40a communicating with the sound-absorbing unit 10 and is disposed on the front side of the sound- The noise generated from the noise source existing outside the front plate 40 is transmitted to the sound absorption unit 10 through the sound absorption hole 40a of the front plate 40 when the sound absorption panel according to the present invention is installed. The face plate 40 faces the side of the road, the railway, or the stationary noise source when the sound-absorbing panel according to the present invention (see reference numeral 100 in FIG. 7) is installed.

For example, the front plate 40 may be made of a metal material or a plastic material. The plurality of sound absorbing holes 40a may be arranged at a constant position and the disposing point of the sound absorbing holes 40a may be formed at a position where the lattice points of the other layers are superimposed so as not to overlap each other. Although not shown, the sound-absorbing holes 40a, which are elongated in correspondence with the width of the front plate 40 in the transverse direction, may be arranged vertically and constantly.

Referring to FIGS. 6A and / or 6B, in one example, the front plate 40 may have a plurality of sound absorbing hole covers 41. FIG. At this time, one side of the sound-absorbing hole cover 41 is connected to the periphery of the sound-absorbing hole 40a and the other side is spaced apart from the sound-absorbing hole 40a to cover the sound-absorbing hole 40a. For example, the sound-absorbing hole cover 41 may be formed by partially boding the front plate 40 so as not to completely penetrate the sound-absorbing hole 40a and bending the piercing hole to form the sound-absorbing hole 40a, When the sound-absorbing hole 40a is completely penetrated in the transverse direction or is formed to be long in the transverse direction, the upper side of the sound-absorbing hole 40a may be formed on the front side by bending the long side of the sound- But it is not limited thereto.

For example, the sound-absorbing hole cover 41 may reflect the sound waves reflected by the front plate 40 in the structure of FIG. 6A to proceed to the sound-absorbing unit 10 through the sound-absorbing hole 40a, The sound wave introduced through the sound-absorbing hole 40a may be reflected to be reflected from the rear side of the front plate 40 and proceed to the sound-absorbing unit 10. [ On the other hand, it is also possible to prevent a sound wave that has passed through the sound-absorbing unit 10 and whose energy is attenuated to be reflected inside and escape to the outside through the sound-absorbing hole 40a. It is necessary to form the sound-absorbing hole cover 41 such that the noise generated from the noise source is minimized so as to be prevented from being transmitted to the sound-absorbing unit 10 through the sound-absorbing hole 40a. In the case of a road or a railway, a sound source is generated mainly on the lower side such as a road or a rail passing through a vehicle or a train, so that the sound-absorbing hole cover 41 does not interfere with the progress of a sound wave inclined from the lower part to the upper part, As shown in FIG. 6A, the sound-absorbing hole cover 41 has one side connected to the upper side of the sound-absorbing hole 40a and extending downward from the outside of the front plate 40, and spaced apart from the sound-absorbing hole 40a So that the sound-absorbing hole 40a can be covered. At this time, noise or the like enters between the sound-absorbing hole 40a and the separated sound-absorbing hole cover 41 and is transmitted to the sound-absorbing unit 10 through the sound-absorbing hole 40a.

6B, one side of the sound-absorbing hole cover 41 is connected to the underside of the sound-absorbing hole 40a, extends upward from the inside of the front plate 40, and is spaced apart from the sound-absorbing hole 40a, And the sound-absorbing hole 40a may be covered on the side of the unit 10. At this time, the noise or the like received through the sound-absorbing hole 40a spreads through the space between the sound-absorbing hole 40a and the sound-absorbing hole cover 41 and spreads to the opened upper side or the upper side and the left and right sides and is transmitted to the sound-

At this time, the sound-absorbing hole cover 41 may prevent rainwater, snow, or other foreign matter from being supplied to the sound-absorbing unit 10 through the sound-absorbing hole 40a.

On the other hand, the front plate 40 is supported by a support frame unit 50 described later. For example, an upper end portion of the front plate 40 may be connected to the upper frame 51, a lower end portion thereof may be connected to the lower frame 55, and both side portions may be connected to the insertion support frame 57.

Referring to FIG. 5, the front plate 40 may be separately manufactured from the support frame unit 50 and coupled to the support frame unit 50. For example, by a fastening means such as a bolt, but is not limited thereto.

Alternatively, although not shown, the front plate 40 may be integrally formed with a part of the support frame unit 50. For example, the front plate 40 and the upper frame 51, the front plate 40 and the lower frame 55, or the front plate 40 and the insertion support frame 57, or a combination thereof, .

Solar cell  The module unit (20)

Referring to Figures 2, 3, 4, 5, 6a and / or 6b, the solar cell module unit 20 comprises a plurality of solar cells 21, And is inclined at the first angle alpha. The solar cell 21 performs solar power generation to obtain electricity from the sunlight. Since the solar cell module unit 20 provided with a plurality of solar cells 21 is well known in the field of solar light, a detailed description of the principle and structure of the solar cell module unit 20 other than those described below will be omitted do. In the example of the present invention, a solar cell module unit 20 which is already manufactured or customized is used.

For example, the solar cell module unit 20 can be supported by the support frame unit 50, which will be described later, at the upper end and the side end. For example, referring to FIGS. 3 to 5, the solar cell module unit 20 may have a coupling portion 25 coupled to the upper frame 51 at an upper end thereof. At this time, the engaging portion 25 may be manufactured separately from the main body of the solar cell module unit 20 and fastened to the main body. The coupling portion 25 is provided with a coupling hole 25a and can be fastened to the coupling hole 51b of the upper frame 51 by a fastening means (not shown) such as a bolt. For example, one of the coupling hole 25a of the coupling part 25 and the coupling hole 51b of the upper frame 51 is formed as a long hole to facilitate the fastening of the upper frame 51 and the solar cell module unit 20 can do. The solar cell module unit 20 may be combined with the support frame unit 50, for example, the upper frame 51, in a manner other than the engagement portion 25 shown in Figs. 3 to 5, for example, .

2 and / or 3, the first angle may be an angle between the rear surface of the sound-absorbing unit 10 and the substrate of the solar cell module unit 20. [ For example, the first angle alpha forms an interior angle of one imaginary triangle with a second angle beta formed by the rear vent plate 30 to be described later. At this time, the first angle? Is smaller than the second angle?. For example, the first angle alpha may range from 5 to 15 degrees. When the solar cell module unit 20 faces the south-east and the first angle? Is 15 °, the sunlight is vertically incident on the solar cell module unit 20 at midnight at midnight at a latitude of 38.5 degrees, At around latitude 37 degrees, sunlight enters the solar cell module unit 20 almost vertically in the vicinity of about 12:30 in the evening. However, when the first angle [alpha] exceeds 15 [deg.], The upper end portion of the solar cell module unit 20 protrudes from the upper portion of the solar cell module unit 20 of the lower sound- The length of the solar cell module unit 20 in the oblique direction is significantly reduced. For example, referring to Table 1 to be described later, when the first angle? Is 15 °, when the second angle? Is reduced to approximately 17 degrees to reduce the shadow effect on the lower sound-absorbing panel, The ratio of the length of the solar cell module unit 20 in the vertical direction to the length in the oblique direction is about 0.55, so that the length of the solar cell module unit 20 in the oblique direction is significantly reduced. At this time, efficient solar power generation effect through the solar cell module unit 20 can not be expected according to the shading or / and reduction of the capacity. It is difficult to expect an effective improvement of the solar power generation efficiency as compared with the case where the solar cell module unit 20 is installed vertically even when the first angle? Is less than 5 degrees.

Further, in one example, the oblique direction length of the solar cell module unit 20 is longer than the oblique direction length of the rear ventilation plate 30 described later.

In one example, the ratio of the oblique direction length of the solar cell module unit 20 to the vertical length of the sound-absorbing panel 100 may range from 0.52 to 0.85. For example, when the first angle is 15 °, the ratio of the oblique direction length of the solar cell module unit 20 to the vertical length of the sound-absorbing panel 100 may be approximately 0.52. At this time, when the ratio of the length of the solar cell module unit 20 in the vertical direction to the length of the sound-absorbing panel 100 is larger than 0.52, when sunlight is incident in the vicinity of about 37 degrees latitude and about 12: When the sound absorbing panel 100 is installed as shown in FIG. 7 by the protrusion of the lower end portion of the solar cell module unit 20, the shadow that is spread on the upper part of the solar cell module unit 20 of the lower sound- If the ratio of the length of the solar cell module unit 20 in the vertical direction to the length of the sound-absorbing panel 100 in the oblique direction is made small, the area of the solar cell module unit 20 is extremely reduced, it's difficult. In addition, when the first angle is 5 °, the ratio of the length of the solar cell module unit 20 in the oblique direction to the vertical length of the sound-absorbing panel 100 may be approximately 0.85. At this time, when the ratio of the length of the solar cell module unit 20 in the vertical direction to the length of the sound-absorbing panel 100 is larger than 0.85, when sunlight is incident in the vicinity of about 37 degrees latitude and about 12: As shown in FIG. 7, when the lower end of the solar cell module unit 20 protrudes, the shadow of the upper part of the solar cell module unit 20 of the lower sound-absorbing panel is gradually enlarged when the sound-absorbing panel 100 is installed. Accordingly, when the embodiment is implemented by gradually deforming the first angle from 5 DEG to 15 DEG, the ratio of the oblique direction length of the solar cell module unit 20 to the vertical length of the sound-absorbing panel 100 is about 0.85 to 0.52 The embodiment can be implemented in such a manner as to reduce the number of times.

For example, in one example, the ratio of the oblique direction length of the solar cell module unit 20 to the oblique direction length of the rear ventilation plate 30 may be in the range of more than 1 and less than 5. For example, if the first angle alpha is 15 degrees and the second angle beta is 15 degrees, the oblique direction length of the rear ventilation plate 30 and the oblique direction length of the solar cell module unit 20 become equal, The ratio of the oblique direction length of the solar cell module unit 20 to the oblique direction length of the rear ventilation plate 30 becomes larger than 1 when the first angle? do. The ratio of the oblique direction length of the solar cell module unit 20 to the oblique direction length of the rear ventilation plate 30 may be 5 or less when the first angle a is 5 °. For example, when the first angle alpha is 5 degrees and the second angle beta is 25 degrees, the ratio of the oblique direction length of the solar cell module unit 20 to the oblique direction length of the rear ventilation plate 30 is 5 .

5, 6A and / or 6B, in one example, the upper end of the solar cell module unit 20 is spaced from the rear surface of the sound-absorbing unit 10. 2 to 3, the upper ventilation hole 51a of the support frame unit 50, which will be described later, is provided on the rear surface between the sound absorption unit 10 and the solar cell module unit 20, The upper end of the solar cell module unit 20 is spaced apart from the rear surface of the sound absorption unit 10 or it can be seen that the support frame unit 50 The upper end of the solar cell module unit 20 may be spaced apart from the rear surface of the sound absorption unit 10 such that the upper frame 51 protrudes horizontally from the insertion support frame 57. [

2 to 4, the solar cell module unit 20 may further include a lead wire 23. At this time, the lead wire 23 is connected to the positive electrode and the negative electrode of the solar cell module unit 20, respectively, and may be exposed to the outside through a side hole 53a of a slant support frame 53 described later. The lead wires 23 exposed through the side holes 53a of the inclined support frame 53 may be connected in series when the sound-absorbing panel according to the present invention is installed.

back side  The vent plate (30)

2, 3, 4, 5, 6a and / or 6b, the rear ventilation plate 30 has a plurality of lower ventilation holes 30a, (20). At this time, the upper end portion of the rear ventilation plate 30 is engaged with the lower end portion of the solar cell module unit 20, and the lower end portion is inclined at the second angle beta with respect to the vertical direction. The lower ventilation hole 30a communicates with the back space S between the sound absorption unit 10 and the solar cell module unit 20. [ At this time, the outside air can be introduced into the rear space S through the lower ventilation hole 30a. As the rear surface of the solar cell 21 is cooled in the rear space S, the heated air is discharged through a ventilation hole 51a, for example, an upper ventilation hole 51a, which will be described later formed on the upper side, It may also be discharged through the hole 30a.

For example, the rear ventilation plate 30 can be supported at the lower end and the side end by the support frame unit 50 described later. The upper end of the rear ventilation plate 30 can be coupled with and supported by the lower end of the solar cell module unit 20. For example, the rear ventilation plate 30 may be fabricated separately from the support frame unit 50 as shown in FIG. 5 or may be integrally formed with a part of the support frame unit 50, although it is not shown. For example, the rear ventilation plate 30 and the lower frame 55 and / or the rear ventilation plate 30 and the inclined support frame 53 may be integrally formed. 5, the rear ventilation plate 30 may include a bend 311 coupled with the solar cell module unit 20 and / or the lower frame 55, A portion for coupling to the solar cell module unit 20 and / or the lower frame 55 coupled with the ventilation plate 30 may be formed as a bent portion 531 of the inclined support frame 53, for example. Although not shown, a coupling hole is formed in the bent portion 311 so that it can be fastened by a fastening means such as a bolt or fastened by welding, gluing or other methods.

For example, the rear ventilation plate 30 may be made of a metal material or a plastic material.

2 and / or 3, the second angle? May be an angle formed between the rear surface of the sound-absorbing unit 10 and the rear ventilation plate 30. FIG. For example, the second angle [beta] forms two interior angles of one virtual triangle with a first angle [alpha] formed by the solar cell module unit 20. [ At this time, the second angle? Is larger than the first angle?. For example, the second angle beta may be in the range of more than 15 degrees and less than 25 degrees. Even if the first angle? Is reduced to 5 degrees, when the second angle? Exceeds 25 degrees, the length of the solar cell module unit 20 in the oblique direction becomes long. Therefore, by the protrusion of the upper end of the rear ventilation plate 30 The upper part of the solar cell module unit 20 of the lower sound-absorbing panel can have a considerable degree of shadow when the sound-absorbing panel is installed. If the second angle beta is less than 15 deg., The length of the rear ventilation plate 30 becomes long and the length of the solar cell module unit 20 in the oblique direction is short The generation capacity of the solar cell module unit 20 is significantly reduced. For example, preferably, in one example, when the first angle alpha ranges from 5 to 15 degrees, the second angle beta ranges from 17 to 20 degrees.

For example, in one example, the oblique direction length of the rear ventilation plate 30 is smaller than the oblique direction length of the solar cell module unit 20. For example, the ratio of the oblique direction length of the solar cell module unit 20 to the oblique direction length of the rear ventilation plate 30 may be in the range of more than 1 and less than 5. For example, when the first angle alpha is 5 degrees and the second angle beta is 25 degrees, the ratio of the oblique direction length of the solar cell module unit 20 to the vertical length of the sound-absorbing panel 100 is about 0.85 And the ratio of the oblique direction length of the solar cell module unit 20 to the oblique direction length of the rear ventilation plate 30 becomes 5. When the first angle? And the second angle? Are both 15 degrees, the oblique direction length of the solar cell module unit 20 and the oblique direction length of the rear ventilation plate 30 are the same, the ratio of the length of the solar cell module unit 20 in the oblique direction to the length of the sound absorbing panel 100 in the vertical direction is about 0.52 when the second angle beta is 15 degrees, The ratio of the oblique direction length of the solar cell module unit 20 to the oblique direction length of the plate 30 exceeds one.

For example, the first angle [alpha] formed by the solar cell module unit 20 and the second angle [beta] formed by the rear vent plate 30, and the length of the rear vent plate 30 And the ratio R of the length in the oblique direction of the solar cell module unit 20 are combined, the approximate values are as shown in the following table. At this time, the ratio of the angle-to-length ratio R and the ratio of the oblique direction length of the solar cell module unit 20 to the vertical direction length of the sound-absorbing panel are all approximate values.

In this case, when the first angle? Is fixed in Table 1, the ratio R of the length in the oblique direction of the solar cell module unit 20 to the length in the oblique direction of the rear ventilation plate 30 is adjusted, It is possible to adjust the ratio R of the oblique direction length of the solar cell module unit 20 to the oblique direction length of the rear ventilation plate 30 by changing the angle? Or adjusting the second angle? have.
