SOLAR PANEL APPARATUS FOR MULTIPLE GENERATION USING A SOLAR ENERGY BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar panel structure capable of combined power generation using sunlight and heat of solar light and capable of combined power generation using solar energy.

Specifically, unlike the prior art in which light incident on a spacing space formed between a plurality of panels is lost in a solar panel that generates power by condensing sunlight, And more particularly, to a solar panel structure for combined power generation using solar energy that allows light to be emitted through the space between the solar cells and reflected from the inside of the solar panel, and to generate heat by heat generated by the reflection process.

With the depletion of fossil fuels, the generation of carbon dioxide resulting from the use of fossil fuels, and the resulting climate change as serious problems, the development of new energy sources to replace fossil fuels is underway worldwide. The most promising of these alternatives is solar energy. Solar energy is the ideal alternative energy because it is continuously supplied as long as the sun and earth are present and does not cause air pollution.

A solar cell is a cell that absorbs solar energy and turns it into electricity. Solar cells include solar cells that generate the steam needed to rotate the turbine using solar heat, and solar cells that convert sunlight into electrical energy using the properties of semiconductors. It means all battery configurations including.

However, the photovoltaic power generation using solar cells has a problem that the energy production cost is much higher than that of thermal power, hydro power, and nuclear power, and the photoelectric conversion rate is not good.

A typical reason is that it is difficult to collect all the sunlight in spite of the always existing sunlight.

In order to solve such a problem, a light-collecting type solar cell abbreviated as CPV (concentrating photovoltaics) has been developed. The light-collecting type solar cell is a solar cell that collects sunlight using a light-collecting means such as a lens or a mirror and supplies the sunlight to the solar cell to improve efficiency. Among the converged solar cells developed to date, the highest efficiency products are GalnP / GalnAs (1.3 eV) / GalnAS (0.9 eV) cells. This solar cell exhibits a conversion efficiency of 41.1% when light is condensed at about 1000x.

Research has been continuing to increase the overall power generation efficiency by operating a thermoelectric element (peltier) having the characteristic capable of converting heat into electricity simultaneously with the solar cell. In other words, among the frequency components that can not be converted by the photoelectric element of the solar cell in the sunlight, the infrared region is received by the thermoelectric element and the heat efficiency is converted into electricity, thereby improving the overall efficiency. In the case of the light-converging type solar cell, since the temperature rise due to the focusing of the sunlight is large, the condensing type solar cell is cooled by combining the thermoelectric elements, thereby enhancing the power generation efficiency and obtaining a larger power generation effect.

On the other hand, there is a power generation system (prior art 1) using a highly efficient condensing type solar power generation system to which a thermoelectric element of Patent Registration No. 10-1134077 is applied in connection with solar power generation.

The prior art 1 relates to a high efficiency condensing type solar power generation system using a solar cell and a solar cell to improve a power generation efficiency and to effectively cool a photoelectric device and a thermoelectric device. A photoelectric element for receiving solar light from the light collecting means and generating electricity; A substrate on which the photoelectric elements are disposed; And a thermoelectric element disposed on a lower surface of the substrate to generate electricity or cool the photoelectric element. The heat generated when the solar photovoltaic device generates solar light is converted from the thermoelectric element to electricity, thereby improving the overall power generation efficiency The present invention provides a high efficiency condensing solar power generation system using a thermoelectric device.

On the other hand, Patent Publication No. 10-0999513 describes a combined power generation apparatus using solar and solar heat (prior art 2).

The prior art 2 relates to a combined power generation apparatus using solar light and solar heat and includes a plurality of solar cell modules each having a solar cell receiver mounted with a solar cell and a first heat sink provided below the solar cell receiver, A thermoelectric generating element provided adjacent to the solar cell module and a heat pipe connecting one end to the solar cell module and connecting the other end to the thermoelectric power generating element.

However, the above-described prior art is different from the technique proposed by the present applicant. Particularly, there is a difference in the structure for generating electric power by solar heat, a structure for protecting the battery from solar heat, and a structure for maintaining airtightness for generating a temperature difference between the inside and the outside of the panel.

Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and are not intended to represent all of the technical ideas of the present invention. Therefore, various equivalents And variations are possible.

Before describing the present invention with reference to the accompanying drawings, it should be noted that the present invention is not described or specifically described with respect to a known configuration that can be easily added by a person skilled in the art, Let the sound be revealed.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar panel structure capable of combined power generation using sunlight and heat of solar light and capable of combined power generation using solar energy.

Specifically, unlike the prior art in which light incident on a spacing space formed between a plurality of panels is lost in a solar panel that generates power by condensing sunlight, And more particularly, to a solar panel structure for combined power generation using solar energy that allows light to be emitted through the space between the solar cells and reflected from the inside of the solar panel, and to generate heat by heat generated by the reflection process.

More specifically, the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a schematic plan view of a solar panel structure for combined power generation using solar energy according to the present invention.

First, according to FIG. 1 of the accompanying drawings,

The solar panel 10 according to the present invention has a form similar to that of a conventional panel that generates electric power using solar light when viewed from above.

That is, a plurality of photovoltaic units 11 are arranged at regular intervals to receive sunlight to generate electricity.

At this time, the sunlight incident on the photovoltaic unit 11 is generated by the electric power, but since the sunlight generally extends in all directions, it is not necessarily incident on the photovoltaic unit 11 at all, The sunlight is also incident on the spaced space, which is the space between the light source 11 and the light source 11, to be lost.

Accordingly, in order to reduce the sunlight energy lost in the present invention, sunlight is projected in a spaced-apart space between the photovoltaic units 11 to transmit heat of the sunlight to the inside of the panel 10, Heat can be used to generate power.

At this time, in the present invention, the spacing space, which is the space between the photovoltaic elements 11, is referred to as a light transmitting portion 12. Therefore, it should be understood that the light transmitting portion 12 does not mean only a space in any one direction as shown in FIG. 1, but also covers the space between the light generating portions 11 even if the light transmitting portion 12 is in another direction.

As a specific structure, reference is made to Fig. 2 of the accompanying drawings.

2 is a cross-sectional view illustrating a structure of a solar panel for combined power generation using solar energy according to the present invention.

According to Figure 2 of the accompanying drawings,

First, the panel 10 will be described in detail. The panel 10 is formed in a box shape having a hollow interior, and has a shape in which one side of the lower surface is broken to maintain airtightness to the extent that the interior is not completely closed And a plate having a length longer than the length of the rupture is supported in the rupture area so as to cover the rupture area.

Both ends of the rupture area of the panel 10 and the plate are configured to be engaged by fastening means such as screws or bolts.

With such a configuration, the inside of the panel 10 can be configured to have a predetermined airtightness although it is not completely closed.

The inside of the panel 10 has a predetermined airtightness in order to prevent the inside of the panel 10 from being affected by the external temperature so that the inside of the panel 10 is warmed up due to the sunlight. However, when the interior of the panel 10 is completely sealed, it is difficult to refract the sunlight, so that the airtightness can be maintained (for example, 70 to 90%).

At this time, the reason why the airtightness of 70 to 90% is maintained is that the temperature inside the panel 10 becomes higher than the outside by 60 ° C or more, so that the temperature difference is maintained.

At this time, the remainder of the panel 10 may be made of a heat-resistant plastic material having transparency, and the plate may be made of a material such as copper or aluminum having high thermal conductivity.

The photovoltaic portion 11 is formed together with the light transmitting portion 12 in the direction in which solar light of the panel 10 is incident.

At this time, the battery 11a is positioned below the photovoltaic unit 11 and the reflection plate 11b is located below the battery 11a. That is, the battery 11a and the reflection plate 11b are housed inside the panel 10, and the battery 11a functions to store the power generated through the photovoltaic unit 11. [

At this time, the battery 11a is illustrated as being formed on the panel 10 in the accompanying drawings, but it may be a structure that can be detachably attached to the panel 10. [ The detachable structure can be applied to any detachable structure that can be derived by a person skilled in the art.

In addition, the battery 11a may not be formed in the panel 10 as shown in the accompanying drawings but may be separately formed outside the panel 10. In this case, the power generated through the photovoltaic unit 11 may be separately supplied to the outside So that the electric wire can be connected so as to be transmitted to the constructed battery 11a.

In this way, when the battery 11a is omitted below the photovoltaic unit 11, the reflector 11b can be positioned immediately. In this case, the reflection plate 11b can prevent the circuit formed on the surface of the photovoltaic unit 11 that is in contact with the panel 10 from being overheated.

Further, the reflection plate 11b is positioned below the battery 11a as described above, thereby preventing sunlight reflected inside the panel 10 from directly touching the battery, as described later. That is, the battery 11a functions to protect the battery 11a against the temperature of sunlight.

'의 단면 형태를 갖도록 구성하되, 상부방향으로 연장되면서 내측으로 경사진 단부들이 배터리(11a)의 측면을 감싸도록 구성될 수 있다.2, the reflection plate 11b protects the battery 11a only in the form of a simple plate. However, in order to efficiently protect the battery 11a, Not the plate form of '

The end portions of the battery 11a are inclined inwardly while extending in the upward direction.

As described later, when sunlight is projected through the lens 13, sunlight transmitted to the side of the battery 11a can be reflected to protect the side of the battery 11a from heat, It is possible to improve the fastening force with the fastening member 11a.

Further, the lens 13 may be positioned below the light transmitting portion 12 of the panel 10 described above. That is, since the light transmitting portion 12 is also made of the same material by the panel 10 made of heat-resistant plastic having transparency as described above, sunlight is easily transmitted, and sunlight transmitted through the light transmitting portion 12, (13), and enters the inside of the panel (10). Alternatively, the light transmitting portion 12 itself may be constituted by the lens 13.

The direction of the sunlight can be referenced to the arrows shown in FIG. 2 of the accompanying drawings. Since the sunlight is also a kind of light, it has an angle that is reflected by an angle corresponding to the incident angle during reflection, And reflects the inside of the panel 10 to heat it.

At this time, the lens 13 may be constituted by a Fresnel lens having a sawtooth shape on one side where sunlight is projected and output according to design conditions.

Accordingly, there is an advantage in that heat transmission to the battery 11a can be prevented because the incident angle to the inside of the panel 10 is narrowed as the sunlight is projected, so that it is not extended in all directions.

The thermoelectric element 14 may be positioned below the plate coupled to the broken region of the panel 10 and the heat sink 15 may be positioned below the thermoelectric element 14. [

In particular, since the solar light is reflected inside the panel 10 and the heat is preserved, particularly, the plate coupled to the broken area of the panel 10 has a high thermal conductivity, so that the temperature of the heat due to the sunlight is transmitted to the thermoelectric element 14 The thermoelectric element 14 generates a predetermined electric power.

Specifically, the thermoelectric element 14 is a Peltier element that generates a predetermined electric power with a potential difference being generated by a temperature difference using the Swwbexk effect.

That is, due to the transfer of the temperature of the sunlight transmitted to the panel of the panel 10, heat generation and endothermic phenomenon occur simultaneously at both ends of the device, thereby generating a temperature difference.

At this time, when the ends of the thermoelectric elements 14 that are in contact with the plate of the panel 10 absorb heat, the opposite ends of the thermoelectric elements 14 in the direction of the heat sink 15 dissipate the heat. And the heat dissipating plate 15 discharges heat from the thermoelectric elements 14. [

Accordingly, according to the solar panel structure capable of combined power generation according to the present invention, sunlight itself can be generated with respect to sunlight energy, and solar light that is lost without being charged can be also projected to a temperature corresponding to the heat of the sunlight. It is possible to provide a combined power generation method that can be developed.

Meanwhile, although the solar panel structure for combined power generation using solar energy according to the present invention is not shown in the accompanying drawings, it may further include a support structure for allowing the panel 10 to move along the direction of the sun .

This enabling of the directional movement of the panel 10 may use both conventional fixed variable or sun tracking methods, and the structure for this may be varied within the predictable range of those skilled in the art.

For example, it may be a configuration in which the supporting bar is installed from the ground, and the length of the panel 10 is adjusted by connecting the supporting bar and the panel 10 (variable fixed type) The angle of the panel may be automatically controlled according to the position of the sun, or the angle of the panel may be controlled based on a pre-stored schedule (sun tracking).

On the other hand, depending on other design conditions, the photovoltaic unit 11 may be configured to be angularly adjusted from the panel 10 by a predetermined angle.

Therefore, the plurality of photovoltaic elements 11 provided on the panel 10 in the direction in which the sunlight is incident, that is, the sun, is angle-adjusted, thereby making the incident light of the incident sunlight more efficient, The reflected sunlight is reflected to the light transmitting portion 12 so that power generation according to the temperature of the heat can be performed.

In this configuration, the remaining area of the panel 10 except for the light transmitting portion 12 is configured to be connected to the photovoltaic unit 11 through a shaft, and the photovoltaic unit 11 can be connected to the photovoltaic unit 11 in one direction For example, from east to west) along the direction of movement of the sun.

On the other hand, according to other design conditions, a heat insulating material or a heat insulating plate having a heat insulating function may be placed on the upper surface of any one of the photovoltaic portion 11 and the light transmitting portion 12. In this case, the meaning of the position may be attachment or simple reinforcement formation.

With this structure, it is possible to prevent the temperature inside the panel 10 from rising sharply by eliminating a part of the temperature of sunlight transmitted through the inside of the panel 10.

It is apparent that the present invention is not limited to the configuration of the drawings, as described above with reference to the drawings, only the main points of the present invention are described, and various designs can be made within the technical scope thereof.
