{Vertically-Installed Bifacial Photovoltaic Module for Multipurpose Soundproof Wall Using Vertical Double-Sided Generation Photovoltaic Module}

TECHNICAL FIELD The present invention relates to a sound barrier wall, and more particularly, to a multi-purpose sound barrier wall capable of soundproofing and solar power generation at the same time.

While traditional power generation methods include thermal power generation using fossil fuels such as coal and LNG, and nuclear power generation using uranium, fossil fuels have been identified as one of the main causes of deepening global warming by discharging greenhouse gases such as carbon dioxide. Power generation has been decreasing due to safety problems after the Fukushima nuclear power plant accident in Japan. As a result of these problems, it is impossible to maintain the energy mix policy that keeps the proportion of fossil energy and atomic energy generation at the current level. Various systems are being implemented in various countries to increase the proportion of environmentally friendly renewable energy.

In order to increase the proportion of renewable energy, the Republic of Korea is fully implementing the Renewable Portfolio Standard (RPS) system from January 1, 2012. The RPS system mandates that power generation companies with a certain size (500MW) or more of power generation facilities (excluding renewable energy facilities) are required to supply more than a certain percentage of total power generation using renewable energy. It is legally required to develop more than 10% of new renewable energy.

Therefore, it is a big opportunity for renewable energy generation companies to supply renewable energy with quota to those who are obliged to do so.

According to the expansion trend of renewable energy, the installation of the photovoltaic power generation system, which is an energy source that can be installed in the most various forms and positions of the renewable energy power generation field, is gradually expanding. However, Finite resources are needed. Currently, due to problems such as the acceptance of residents, there is a limited amount of land available for installing PV systems. On the other hand, the social demand for renewable energy is increasing day by day. It is a situation that is required.

In accordance with these socio-economic needs, the photovoltaic power generation system is required to be installed on existing road and railway soundproofing walls which are used for one purpose. However, the conventional single-sided photovoltaic power generation module and system have a large difference in generation amount depending on the installation orientation and inclination angle. When installed on the vertical soundproof wall using existing single-sided photovoltaic module and system, the generation amount is 40% The actual solar photovoltaic wall is not installed properly because the power generation is only about 15% of the PV power generation system and commercialization is low.

A patent for a conventional sound barrier including a solar module is as follows. Patent No. 10-1447448 discloses a technique for a solar power generation type soundproofing wall in which a built-in soundproof panel having a sectional light receiving solar module is sandwiched between strut members in a "solar power generation soundproofing wall ". On the other hand, in the patent registration No. 10-1334362 entitled " Photovoltaic Soundproofing Wall ", a photovoltaic module has a solar power generation type soundproofing wall capable of performing two functions of sound insulation and power generation.

Conventional soundproof walls including the above-mentioned patents all suffer from the power generation efficiency because they both receive and generate solar light on only one side by using a sectional light receiving solar module. In order to overcome such a problem, there has been disclosed a technique of installing a solar module on the front and rear surfaces of a sound barrier, respectively. However, such a technology has a problem in that the device becomes complicated and the installation cost rises.

As described above, due to the limitation of the vertical installation in the case of the soundproof wall having the function of generating the conventional solar module, only about 40% of the power generation is produced compared to the inclined fixed solar power generation system, It is actual condition. However, according to the present invention, since the solar power is generated on both sides even when the double-side power generation type solar module is applied to the vertically erected sound barrier, the power generation efficiency similar to that of the conventional tilting fixed solar cell system is exhibited.

Hereinafter, the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a multi-purpose sound barrier using a vertical two-sided power generation type solar module according to a preferred embodiment of the present invention, FIG. 2 is a perspective view of a double- to be. Only two strut members 10 out of the soundproof walls extending for at least several tens of meters in the left and right direction are illustrated.

The strut members 10 are installed apart from each other along the boundary side of the noise generating section, and the strut member 10 has a bar shape or a rod shape as a whole. The strut member 10 increases or decreases in accordance with the total length of the soundproof wall provided as a supporting member of the soundproof wall or as a structural member serving as a skeleton. The height of the support member 10, the length, the distance between the support members and the like are determined according to the situation of the construction site. The support member 10 may be installed directly on the ground surface, but may be installed on the concrete installation surface. The strut member is preferably H-shaped (or I-shaped) steel because the double-surface-generating solar module 20 described later can be fitted to the groove portion of the H-shaped steel. However, since the photovoltaic module 20 can be coupled between the strut members 10 by a very wide variety of known methods (for example, bolt fastening or the like), the strut member 10 must be H- It does not have to be a section steel.

The double-sided power generation type solar module 20 will be described with reference to Fig. Two-sided power generation type solar modules 20 are stacked one on top of the other or a plurality of the sided type solar modules 20 to correspond to the vertical height of the strut members 10. For convenience of explanation, Hereinafter, a stacked embodiment will be described.

The double-sided power generation-type solar cell module 20 is generally configured by arranging dozens of double-side power generation-type solar cells 21 between two transparent planar substrates (glass or light-transmitting material, also referred to as "backsheet" The double-side power generation-type solar module 20 itself is a well-known technology, and a detailed description thereof will be omitted in the present invention.

The double-sided power generation type solar module 20 further includes a junction box 25 and power terminals 22 and 23 in addition to the cell 21.

The junction box 25 receives all the power generated from the plurality of cells 21 in the double-sided power generation type solar module 20 and distributes the power to the outside again. The junction box 25 includes a negative power source terminal 22, (Which may be set as a terminal) and a positive power terminal 23 (which may be set as a negative power terminal). It is preferable that the junction box 25 is installed on the side where the cell 21 is not disposed, not the front or rear surface where the cell 21 is disposed so as not to block the sunlight to be received.

In the present invention, the power terminals 22 and 23 are socketed so that the wiring operation between the two-sided power generation type solar modules 20 stacked on each other is not separately required, thereby minimizing the installation period. Conventionally, a separate wiring work has been performed for wiring between the solar modules. However, there has been a problem of installation errors due to an increase in construction period. However, in the present invention, the power terminals 22, 23 are sockets, The double-sided power generation type solar modules 20 electrically connect to each other electrically only without stacking the modules 20 without wiring work. One of the power terminals 22 and 23 is located on the upper side and the lower side of the double-sided power generation type solar module 20 and is connected to a power terminal Is located at a position corresponding to the power supply terminal on the lower side of the double-sided power generation-type solar cell module 20 stacked thereon, whereby electrical connection is made.

In the meantime, the present invention not only guides the stacking position of the double-side power generation type solar module 20 stacked on top and bottom, but also has a fitting portion 24 so as to prevent the deviation. The fitting portion 24 may be located on the upper side or the lower side of the double-side power generation-type solar module 20, and in the drawings, the fitting portion 24 is shown on the upper side. However, in the case where the fitting portion 24 is located on the upper side, the solar cell module 20 having the double-sided power generation type solar cell module 20 stacked up and down is required to have the fitting portion 24 on the upper side.

In the present invention, the fitting portion 24 is composed of two plate members (having a larger area than the thickness) provided on the upper side of the double-side power generation-mode solar module 20 so as to be spaced apart from each other, And the bottom surface of another double-sided power generation-type solar module 20 stacked on the groove is fitted.

A plurality of double-sided power generation type solar modules 20 are referred to as strings. In order to provide electrical connection between different strings, the negative electrode terminals 22 of the uppermost double- A string jumper connector 40 is connected. Of course, since the string jumper connector 40 may be connected to the lowermost two-sided power generation solar module 20, the scope of the present invention is not limited to the specific position.

The control panel 30 includes a connection panel 31 and an inverter 32. Since the control panel 30 is also fitted between the support members 10, . In addition, the controller 30 also has a fitting portion 34 on the upper side to guide the position of the double-side power generation-type solar module 20 stacked on the upper side, It is preferably the same as the fitting portion 24 of the module 20. Although not shown in the drawing, a power terminal corresponding to the positive terminal 23 of the double-sided power generation type solar module 20 may be provided on the upper side of the control panel 30 in a socket manner.

3 is a view for explaining an electrical connection state between the double-side power generation-type solar module 20 and the control panel 30 according to the present invention. As described above, in the present invention, The power supply terminals 22 and 23 can be connected without any additional wiring work.

FIG. 4 shows another embodiment of the present invention, which is a sound barrier further including the billboard 60, and can drive the billboard 60 using the power generated from the double-side power generation type solar module 20. FIG. Conventionally, the installation cost for connecting the power source from the outside is required for supplying the power to the billboard 60, but in the present invention, the power is directly supplied through the photovoltaic power generation in the field, The billboard 60 can be easily installed and the operation cost is very low.

5 shows another embodiment of the present invention in which a streetlight 70 is further provided in addition to the above-mentioned billboard 60 as a soundproof wall further comprising a streetlight 70. [
