Description

TECHNICAL FIELD

The present disclosure relates to a solar panel structure and a solar panel assembly including the same, and more particularly, to a solar panel structure which allows simple structural and electrical connections and variable installations, and a solar power generation system having a solar panel structure including the solar panel structure.

BACKGROUND ART

As reserves of existing energy resources such as oil or coal are decreasing and environmental pollution caused by existing energy resources becomes serious, an interest in alternative energy sources to replace the existing energy resources is increasing. Among the alternative energy sources, solar cells are eco-friendly energy devices that utilize infinitely provided sunlight and do not cause environmental pollution, and research on relevant technologies is being actively conducted.

Solar cells are electrical devices configured to convert solar energy into electricity, and currently, a crystalline silicon-based material is mainly used.

Recently, not only various technologies for increasing efficiency of solar cells, but also technologies utilizing solar cells, i.e., technologies relevant to various devices and services using solar panels are being variously proposed. As examples, technologies of connecting a plurality of solar cells with each other to implement solar panel products for charging smartphones, solar panel products for charging auxiliary batteries, foldable-type solar panels, flat-type solar panels, etc. are being introduced.

According to Korean Patent Publication No. 10-1952824, a mono-facial light-receiving solar cell applicable to small-scale power-consuming devices such as a sign device is disclosed. According to this technology, a solar panel structure configured to include a structure providing a mounting space of a solar cell panel and the solar cell panel mounted in the structure is provided. It is disclosed that this technology allows to perform stable solar power generation regardless of a position of the sun, and simultaneously, improve convenience of installation and maintenance. According to Korean Patent Publication No. 10-1700955, a hand-held type solar cell panel held by a person and capable of charging various portable devices has been proposed. The hand-held type solar cell panel includes a printed circuit board on which a circuit pattern is provided, and a substrate for a solar cell panel including a first plated layer having a shape of a discontinuous strip disposed along an upper surface, a lower surface, and side surfaces of edges of the printed circuit board.

Such general solar power generation devices (solar charging devices, solar panels, etc.) may help to improve convenience to a certain degree, but may still have various problems.

In detail, since general solar power generation devices generate electricity by receiving sunlight, a power generation output is determined in proportion to conversion efficiency and a size of a panel capable of absorbing sunlight. However, since light-receiving areas are determined constantly in the general solar power generation devices, an amount of power generation is fixed. Thus, an amount of power generation cannot be changed or is structurally very difficult to change.

In addition, due to a standardized shape of a solar panel, an area receiving sunlight cannot be increased, and when there is an obstacle, the solar panel cannot be installed, and installation can be performed only when a space having a certain size is secured. Therefore, efficient use of a space cannot be performed or is very difficult to perform.

In addition, it is also difficult to cope with a change in a demand for power as needed. That is, since it is difficult to increase or decrease an amount of power generated, a solar panel needs to be replaced when power is to be generated in correspondence with an amount other than a determined power generation amount. This eventually causes an increase in waste of resources such as generation of waste panels, and an increase in costs of management such as maintenance, etc.

Therefore, to obviate those problems, there is a need to develop a new concept of a solar panel structure which allows simple mechanical and electrical connections and variable installations as needed.

FIG. 1 is a diagram illustrating a shape of a general solar panel. FIGS. 2 to 4 are schematic configuration diagrams of a solar power generation structure according to an embodiment of the present disclosure.

As illustrated in FIG. 1A, general solar panels are provided to have a flat plate form having approximately a square or rectangular shape. The solar panels constitute a panel module through various combinations, and may be provided, for example, in a matrix form as shown in FIG. 1B.

FIG. 2 is a schematic configuration diagram illustrating a concept of a solar power generation structure according to an embodiment of the present disclosure. As shown in FIG. 2A, a solar panel assembly 1 may include a plurality of panel structures 10 combined with each other. Additionally, as shown in FIG. 2B, in addition to the combination of the panel structures 10, a power supply unit 20 and a controller 30 may be further included.

The power supply unit 20 may be, for example, a secondary battery, and there is no particular limit in a type and a form of the power supply unit 20. The controller 30 is a device configured to collect direct current electricity generated by solar power to connect to an external output terminal at a constant voltage. For example, the junction box 14 may be a controller.

However, the solar panel assembly 1 according to an embodiment of the present disclosure may be used by combining the plurality of panel structures 10 with each other in correspondence with a desired form and number, thus allowing efficient use of an area. Accordingly, a light receiving area may be maximized or optimized.

In addition, as shown in FIG. 3B, when an obstacle (or obstacles) is located in a space in which installation is to performed, the installation may be performed by avoiding the obstacle (or the obstacles) through assembling of the panel structures 10. In addition, as shown in FIG. 3B, the panel structures 10 may be assembled to have a hollow area v to obtain an aesthetic design of a shape. A sign board, an information board, a transparent panel, a mirror, etc. may be installed in the hollow area v. That is, the solar panel assembly 1 according to an embodiment of the present disclosure may be a power generation structure including the panel structures 10, and various functions may be implemented by installing a non-power generation structure together with the power generation structure in the hollow region v.

FIG. 4 illustrates a form of combination between various panel structures 10 in the solar panel assembly 1 according to an embodiment of the present disclosure. General photovoltaic modules have a serial connection structure. However, the solar panel assembly 1 according to an embodiment of the present disclosure may have a structure in which the panel structures 10 are electrically connected in parallel to each other.

The panel frame 110 is a frame which covers the solar panel 130 configured to receive sunlight, and other elements such as the magnet 150, the metal plate 170, the wiring 190, and the insulating material 210.

The solar panel 130 is provided below or above the panel frame 110 and functions to generate energy by receiving sunlight.

The magnet 150 according to an embodiment of the present disclosure may include a first magnet 151 and a second magnet 153.

Referring to FIG. 7A, the first wiring 191 according to the present embodiment may connect the first magnet 151 to a negative (−) electrode among electrodes 133 disposed on an electrode surface 131 of the solar panel 130.

As shown in FIG. 7B, the second wiring 193 may connect the second magnet 153 to a positive (+) electrode among the electrodes 133 disposed on the electrode surface 131 of the solar panel 130.

The first wiring 191 and the second wiring 193 according to the present embodiment may be implemented to be disposed along an edge of the solar panel 130 to extend to the electrodes 133 via the magnets 151 and 153 and the metal plates 171 and 173 by coming in contact with the magnets 151 and 153 and the metal plates 171 and 173.

For example, the first wiring 191 and the second wiring 193 according to an embodiment of the present disclosure may be implemented as a nickel or copper strip.

In addition, as shown in FIG. 8, in the second wiring 193 located at the second height according to the present embodiment, a stepped portion for a connection with respect to a height difference between the second height in the panel frame 110 and a height of the solar panel 130 below the panel frame 110 may be provided to connect an electrode on the electrode surface 131 to the second magnet 153.

Referring back to FIG. 5, the insulating material 210 according to an embodiment of the present disclosure is made of an insulating material, and may be disposed between the first magnet 151 and the first wiring 191, and between the second magnet 153 and the second wiring 193, to insulate between the first wiring 191 and the second wiring 193.

The panel frame 110 in the present disclosure may include first corner pockets 111 in a corner portion at the first height, and second corner pockets 113 in a corner portion at the second height above the first height, wherein the first magnet 151 and the first metal plate 171 may be arranged in the first corner pockets 111 and the second magnet 153 and the second metal plate 173 may be arranged in the second corner pockets 113.

The insulating material 210 may constitute first insertion pockets 211 in a corner portion at a first height corresponding to the first height of the panel frame 110, and second insertion pockets 213 in a corner portion at a second height corresponding to the second height in the panel frame 110, wherein the first magnet 151 and the first metal plate 171 may be at least partially inserted into the first insertion pockets 211, and the second magnet 153 and the second metal plate 173 may be at least partially inserted into the second insertion pockets 213.

The panel frame 110, the solar panel 130, the magnet 150, the metal plate 170, the wiring 190, and the insulating material 210 in the present disclosure may all be configured to have a quadrilateral form. The magnet 150, the metal plate 170, the wiring 190, and the insulating material 210 may be stacked between the panel frame 110 and the solar panel 130. As shown in FIG. 6, the wiring 190 and the insulating material 210 are not viewable as being covered by the panel frame 110 when viewed from outside. A light-receiving surface of the solar panel 130 is disposed to have an exposed form in a lower surface of the solar panel structure 100 to receive sunlight.

FIG. 8 is an X-axis sectional view of the solar panel structure according to an embodiment of the present disclosure.

Referring to FIGS. 6 to 8, the first magnet 151 may be disposed in first corner pockets in a diagonal direction, among the first corner pockets 111. That is, four first corner pockets 111 are disposed in corner portions at the first height in the panel frame 110 having a quadrilateral shape. The first magnet 151 is disposed in two first corner pockets 111 in a diagonal direction, among the four first corner pockets 111, and the first metal plate 171 is disposed in other two first corner pockets 111 (see FIG. 7).

Likewise, the second magnet 153 may be disposed in second corner pockets in a diagonal direction, among the second corner pockets 113. Four second corner pockets 113 are disposed in corner portions at the second height of the panel frame 110 having a quadrilateral shape. In this case, the second magnet 153 is disposed in two second corner pockets 113 in a diagonal direction, among the four second corner pockets 113. The second metal plate 173 is disposed in other two second corner pockets 113 (see FIG. 7).

At this time, the first magnet 151 and the second magnet 153 in the present disclosure are both located in the corner portions of the panel frame 110, but need to be implemented to be arranged in different corner portions in a vertical direction.

As shown in FIG. 6, the second metal plate 173, other than the second magnet 153, is disposed on the first magnet 151 in the corner portion of the panel frame 110 in which the first magnet 151 is disposed. Likewise, the first metal plate 171, other than the first magnet 151, is disposed below the second magnet 153 in the corner portion of the panel frame 110 in which the second magnet 153 is disposed.

The above-described arrangement of the first magnet 151, the second magnet 153, the first metal plate 171, and the second metal plate 173 may prevent generation of a repulsive force and generate only an attractive force to facilitate a combination between different solar panel structures 100 when the different solar structures 100 are to be combined with each other.

FIG. 9 is a schematic diagram illustrating a combination between solar panel structures according to an embodiment of the present disclosure.

As shown in FIG. 9, the first magnet 151 and the second magnet 153 according to an embodiment of the present disclosure are alternately arranged in four corner portions. Thus, when combination with another solar panel assembly is performed, an attractive force is generated. Therefore, the combination may be easily performed.

In detail, the first magnet 151 may create a strong attractive force with the second magnet 153 and the first metal plate 171 of another solar panel structure combined with one side, and the second magnet 153 may create a strong attractive force with the first magnet 151 and the second metal plate 173 of the another solar panel structure combined with one side.

FIG. 10 is a diagram illustrating a shape of an assembled-type solar panel assembly constituted by combining a plurality of solar panel structures with each other according to an embodiment of the present disclosure.

As shown in FIG. 10, since the solar panel structure in the present disclosure has magnets arranged in the four corner portions, respectively, an attractive force is generated at all of four corner points. Thus, the solar panel structure may not be easily separated from, but may be stably combined with solar panel assemblies arranged in all directions.

FIG. 11 illustrates an example of a combination between solar panel structures according to an undesirable embodiment.

A left drawing in FIG. 11 illustrates a state in which a repulsive force is generated due to incorrect setting of a combination direction of solar panel structures in the present disclosure, and thus, the solar panel structures are not combined with each other.

A right picture of FIG. 11 illustrates a state in which a first magnet (an S pole) and a second magnet (an N pole) are not alternately arranged in four corner portions of a solar panel structure but the first magnet (an S pole) is on a left side and the second magnet is on a right side, and accordingly, in combination between different solar panel structures, an attractive force is generated in one corner portion, but a repulsive force is generated in another corner portion since two magnets with a same polarity meet (an N-pole).

In addition, the assembled-type solar panel assembly according to an embodiment of the present disclosure may include only a plurality of solar panel structures, but may also be implemented to have a combination structure of a non-power generation panel structure and a solar panel structure (a power generation panel structure). In this case, the non-power generation panel structure does not include a solar panel only, and arrangement of magnets (S-pole, N-pole) to be combined with other structures may be performed identically.

FIG. 13 is a diagram illustrating a rear surface of the solar panel structure using the assembly block according to an embodiment of the present disclosure.

The panel frame 320 is a frame which covers all elements including the solar panel 310 configured to receive sunlight, the electrodes 330, the conductor pad 340, and the magnet 350. In detail, the panel frame 320 in the present disclosure covers a portion (a side surface and an electrode surface) of the solar panel 310, other than a light-receiving surface configured to receive sunlight. A plurality of pattern grooves 325 may be disposed in a rear surface covering the electrode surface of the solar panel 310.

Referring to FIG. 13, the pattern grooves 325 which may be coupled to the assembly block 400 are disposed to be apart from each other in the rear surface of the panel frame 320 according to an embodiment of the present disclosure, and the pattern grooves 325 may be arranged in a whole area of the rear surface of the panel frame 320 other than an area in which the electrodes 330 are disposed.

Meanwhile, a plurality of exposure grooves for exposing the plurality of electrodes 330 arranged in an edge portion of the solar panel 310 to outside may be disposed in a side surface of the panel frame 320. The electrodes 330 are exposed to outside through the exposure grooves to be connected to a control device to transmit direct current electricity to the control device. Thus, the control device may collect direct current electricity generated by solar power to connect to an external output terminal at a constant voltage.

The electrodes 330 may be disposed to be apart from each other by a certain distance in an edge portion of the panel frame 320. The electrodes 330 in the present disclosure may include first electrodes 331 and second electrodes 333 having different polarities. The first electrodes 331 and the second electrodes 333 may be arranged alternately with each other.

For example, in the present embodiment, the first electrodes 331 may be positive electrodes and the second electrodes 333 may be negative electrodes.

Referring to FIGS. 12 and 13, the first electrodes 331 may be arranged in both side portions of each side of the solar panel 310 and the panel frame 320 each having a rectangular shape, and the second electrodes 333 may be arranged between the first electrodes 331 arranged in the both side portions.

That is, the first electrodes 331 may be implemented to be disposed in corner portions of the solar panel 310 and the panel frame 320, and the second electrodes 333 may be implemented to be disposed at a center of edge portions of the solar panel 310 and the panel frame 320.

A first magnet 351 and a second magnet 353 may be disposed on surfaces of two first electrodes 331 in contact with a first conductor pad 341 disposed in a corner portion of the solar panel 310, respectively.

The magnets 350 may function to facilitate combination with other solar panel structures and guide alignment of a plurality of solar panel structures arranged in parallel.

For example, as an attractive force occurs between a first magnet 351 located at an upper right end of a first solar panel structure, and a second magnet 353 located at an upper left end of a second solar panel structure to be combined with a right side of the first solar panel structure, positional alignment of the first solar panel structure and the second solar panel structure may be smoothly performed.

In addition, as shown in FIG. 14, the magnets 350 in the present disclosure has a structure in which the first magnets 351 and the second magnets 353 are arranged symmetrically to each other at each corner. Thus, when combination with another solar panel structure is performed, any of four surfaces may be combined with the another solar panel structure without any restriction.

A plurality of pattern grooves 525 may be disposed in a rear surface covering the electrode surface of the solar panel 510.

In addition, the panel frame 520 in the present disclosure may include magnet pockets 523 configured to provide spaces in which the magnets 530 may be arranged inside. The magnet pockets 523 are disposed in an edge portion of the panel frame 520.

The magnets 530 may be located in an edge portion of a solar panel to be combined with another solar panel. The magnets 530 according to an embodiment of the present disclosure may be configured in a circular shape.

Referring to FIG. 20, the pattern grooves 525 capable of being coupled to an assembly block are disposed to be apart from each other in a rear surface of the panel frame 520 according to an embodiment of the present disclosure.

Meanwhile, a plurality of exposure grooves for exposing the plurality of magnets 530 arranged in an edge portion of the solar panel 510 to outside may be disposed in a side surface of the panel frame 520. The magnets 530 are exposed to outside through the exposure grooves to be connected to a controller 600 to transmit direct current electricity to a control device. Thus, the controller 600 may collect direct current electricity generated by solar power to connect to an external output terminal (e.g., an external battery) at a constant voltage.

FIG. 21 is a schematic diagram illustrating separation of a solar panel from a panel frame according to an embodiment of the present disclosure.

In addition, the magnets 530 disposed on the panel frame 520 may be exposed in a front surface of the panel frame 520 to be electrically connected to electrodes 513 and 515 on the electrode surface of the solar panel 510.

The magnets 530 according to the present disclosure are located inside the magnet pockets 523 disposed in an edge portion of the panel frame 520.

FIG. 22A is a diagram illustrating a front surface portion of the panel frame 120. FIG. 22B is diagram illustrating a state in which the magnets 530 are inserted into the magnet pockets 523.

Referring to FIG. 22A, the magnet pockets 523 provide spaces so that the magnets 530 may be coupled to the panel frame 520. The magnet pockets 523 are disposed on the edge portion of the panel frame 520. More preferably, the magnet pockets 523 according to an embodiment of the present disclosure may be disposed in corner portions of the panel frame 520.

The magnet pockets 523 may be configured to have a circular shape corresponding to a circular shape of the magnets 530 in an inward direction of the panel frame 520, and have a flat shape on a side surface of the panel frame 520.

FIG. 23A is an enlarged view of the magnet pockets 523. FIG. 23B is an enlarged view of the magnets 530 inserted into the magnet pockets 523.

According to an embodiment of the present disclosure, exposed grooves 521 are disposed in positions in which the magnet pockets 523 are disposed in a side surface of the panel frame 520.

Referring to FIG. 23B, parts of side surfaces of the magnets 530 are exposed to outside through the exposure grooves 521. The magnets 530 in the present disclosure need to be mechanically and electrically combined with to another external solar panel structure. This mechanical and electrical combination may be performed by being exposed to outside through the exposure grooves 521.

Further, inner spaces of the magnet pockets 523 in which the magnets 530 are arranged are configured to have a size greater than that of the magnets 530. Thus, positions of the magnets 530 in the magnet pockets 523 may be moved by a certain distance depending on whether the magnets 530 are combined with another solar panel.

FIG. 24 is a schematic diagram illustrating movement of positions of magnets within magnet pockets according to an embodiment of the present disclosure. FIG. 24A shows that the magnets 530 are inserted into the magnet pockets 523 before being combined with another solar panel structure. FIG. 24B shows that positions of the magnets 530 are moved within the magnet pockets 523 when being combined with another solar panel structure.

In detail, as the solar panel structure 500 is positioned adjacent to another solar panel structure, the magnets 530 move in an outward direction due to occurrence of an attractive force with magnets in the another solar panel structure.

According to an embodiment of the present disclosure, magnets disposed in an edge portion of the panel frame 520 may be alternately arranged so that upper surfaces of adjacent magnets have different polarities.

According to one embodiment, referring to in FIG. 24, the magnets may be preferably arranged, for example, to have a form in which an S pole 533 as a second magnet is arranged next to an N pole 531 as a first magnet.

FIGS. 25 to 28 are diagrams illustrating movement of magnets when different solar panel structures are positioned adjacent to each other.

FIG. 26 is a detailed enlarged view for explaining a state in which the magnets 530 are inserted into the magnet pockets 523 before being combined with another solar panel structure.

In detail, referring to FIG. 26, with respect to a state of magnets inside magnet pockets 523a and 523b before combining with another solar panel structure, since a distance between a first magnet 531 and a second magnet 533 is comparatively small, the magnet 531 and the magnet 533 are located in an inward direction within the magnet pocket 523 due to an attractive force.

According to an embodiment of the present disclosure, a radius R₁ of the magnets may be 2.8 mm to 3.2 mm, a radius R₂ of the magnet pocket 523 may be 2.9 mm to 3.7 mm, and a distance A from an outer wall (an end) of the panel frame 520 in which the magnet pockets 523 are disposed to a center of the first or second magnet 531 or 533 may be 2.8 mm to 3.2 mm.

In an optimal embodiment of the present disclosure, the radius R₁ of the magnets may be 3.0 mm, a radius R₂ of the magnet pockets 523 may be 3.1 mm to 3.5 mm, and the distance A from an outer wall (an end) of the frame 520 in which the magnet pockets 523 are disposed to a center of the magnet 131 or 133 may be 3.0 mm.

In this case, in a case when the distance A is equal to or longer than the radius R₁ at a point where a distance B between the magnet pockets 523a and 523b adjacent to each other is shortest, when external magnetic force is not present, such an effect that the magnets 531 and 533 may be moved and positioned in an inward direction may be obtained.

Referring to FIG. 27, as two solar panel structures become adjacent to each other, an attractive force is generated between adjacent magnets. Thus, positions of the magnets 531 and 533 move in an outward direction within the magnet pocket 523. Accordingly, as shown in FIG. 28, panel frames of different solar panel structures come into contact with each other, and thus, the magnets 531 and 533 that have generated an attractive force return to original positions (located in a center) in the magnet pockets 523, respectively, due to relative position movement according to movement of the panel frames 520.

Then, when a combination between the panel frames 520 is released, the magnets 530 inside the magnet pocket 523 will move back in an inner direction of the magnet pockets 523 as illustrated in FIG. 26.

FIG. 29 is a schematic diagram illustrating an electrode surface of a solar panel structure according to various embodiments of the present disclosure.
