Technical Field

The invention relates to a solar cell module comprising a solar cell panel and a reflector plate and a method for adjusting the reflector plate.

Background

Generally, a solar cell module is completed by a process of connecting electrode wires of cells using a copper tape and laminating and pressing in order of a back sheet, Ethylene Vinyl Acetate (EVA), a solar cell, EVA, and a cover glass, a process of trimming edges of the pressed laminate with an aluminum frame, and a process of installing a junction box for connecting the copper tape to an output cable.

Generally, a solar cell module is mounted without a reflection plate, or even when a reflection plate is provided, the reflection plate is arranged to form a predetermined angle with a solar cell panel. Since the incident angle of sunlight continuously changes as time passes when the reflection plate arranged as described above is fixed, the reflection effect of the reflection plate may change according to time, the effect of the reflection plate may be limited to a specific time zone, and a shadow may be generated on the solar cell panel even by the reflection plate to reduce the power generation efficiency.

Disclosure of Invention

Technical problem

An object of the present invention is to provide a solar cell module and a method for adjusting a reflection plate of the solar cell module, which prevent a shadow of the reflection plate, which may be generated according to a solar path change, to improve power generation efficiency.

Another object of the present invention is to provide a solar cell module capable of increasing power generation per installation area and/or per solar cell panel to allow efficient and economical solar cell power generation.

Technical scheme

In a first aspect of the present invention to achieve these objects, a solar cell module includes a solar cell panel and a reflection plate connected to and disposed on an edge of the solar cell panel, and an angle between the reflection plate and a surface of the solar cell panel is changed.

As described above, the angle between the reflection plate connected to and disposed on the solar cell panel and the solar cell panel may be varied according to the solar path change to improve the solar power generation efficiency.

In the first aspect of the present invention, when the solar cell panel faces south, the reflective plates may include a first reflective plate disposed on the east side and a second reflective plate disposed on the west side, and the angle between the surface of the solar cell panel and the surface of the first reflective plate and the angle between the surface of the solar cell panel and the surface of the second reflective plate may be simultaneously or individually changed.

In the first aspect of the invention, the angle between the reflective plate and the surface of the solar panel may vary along the solar path.

In the first aspect of the present invention, the angle between the reflective plate and the surface of the solar cell panel may be varied within a range from 60 ° to 180 °.

The solar panel of the present invention may be arranged to face south. For example, a first reflective sheet disposed on the east side is parallel to the solar cell panel and is fully unfolded at sunrise to form 180 °, and a second reflective sheet disposed on the west side, i.e., the opposite side, may be inclined at 60 ° with respect to the solar cell panel to concentrate sunlight. When the angle is less than 60 °, the area receiving the sunlight may be too small.

In the first aspect of the present invention, the width of the reflection plate is larger than the width of the solar cell panel. When the width of the reflection plate is formed to be greater than the width of the solar cell panel, the amount of reflection may be increased to improve power generation efficiency.

In the first aspect of the present invention, the reflection plate may include one or both of a third reflection plate connected to and disposed on an upper edge of the solar cell panel and a fourth reflection plate connected to and disposed on a lower edge of the solar cell panel.

Since the reflection plate is connected to and disposed on the upper edge and/or the lower edge in addition to both sides of the solar cell module, the reflectivity may be increased to improve the solar power generation efficiency.

In the first aspect of the present invention, the angle between the surface of the solar cell panel and the surface of the third reflection plate and the angle between the surface of the solar cell panel and the surface of the fourth reflection plate may be changed simultaneously or individually.

In the first aspect of the present invention, the solar cell module may further include an illuminance sensor, and when the motor configured to change the angle is connected to the reflection plate, the motor may be driven to rotate the reflection plate, thereby maximizing illuminance by using the illuminance sensor.

In particular, when the inner angle α 5 between the first and second reflection plates is maintained to be 60 ° and the illuminance sensor maintains the maximum illuminance, the angle of each of the first and second reflection plates may be adjusted. When the angles α 1 and α 2 to the solar cell panel are changed according to the solar path while maintaining the internal angle between the first reflection panel and the second reflection panel constant, the power generation amount can be maximized. As described above, since the internal angle is constantly maintained, when the solar path is changed, the first reflection plate and the second reflection plate may be symmetrical to the incident light, and the incident angle and the incident amount of the solar light incident to the surface of the solar cell panel may be uniformly adjusted and optimized to increase the power generation amount.

In a second aspect of the present invention to achieve these objects, a method for adjusting a reflection plate of a solar cell module according to the first aspect includes adjusting an angle between the reflection plate and a surface of a solar cell panel so that sunlight is always incident on the surface of the reflection plate.

When a shadow is generated by the reflection plate according to a solar path change, the solar cell efficiency may be reduced, which may be prevented by adjusting the angle of the reflection plate.

In the second aspect of the present invention, the method may further include: before 10 am, maintaining an angle of a surface of each of the first and second reflection plates to a surface of the solar cell panel at 180 °; maintaining an angle of a surface of each of the first and second reflection plates to a surface of the solar cell panel at 120 ° from 10 am to 2 pm; and after 2 o' clock in the afternoon, maintaining an angle of the surface of each of the first reflection plate and the second reflection plate to the surface of the solar cell panel at 180 °.

In the second aspect of the present invention, the method may further include: before 10 am, the angle of the first reflection plate to the surface of the solar cell panel is maintained at 180 °, and the angle of the second reflection plate to the surface of the solar cell panel is maintained at 120 °; maintaining an angle of each of the first and second reflection plates to a surface of the solar cell panel at 120 ° from 10 am to 2 pm; and after 2 o' clock in the afternoon, maintaining the angle of the first reflection plate to the surface of the solar cell panel at 120 °, and maintaining the angle of the second reflection plate to the surface of the solar cell panel at 180 °.

In the second aspect of the present invention, the angle between the reflective plate and the surface of the solar cell panel may be adjusted such that the internal angle between the first reflective plate and the second reflective plate always forms 60 °, and sunlight is always incident to the surface of the reflective plate.

In a third aspect of the present invention to achieve these objects, two or more solar cell panels may be provided, and a reflection plate may be disposed at one side or both sides of the two or more solar cell panels in a direction crossing a virtual center line between the two or more solar cell panels.

In a fourth aspect of the present invention to achieve the objects, two or more solar cell panels may be provided, the two or more solar cell panels may be arranged to face each other such that a sunlight incident surface of one solar cell panel is inclined at a predetermined angle with respect to a sunlight incident surface of the other solar cell panel, and a reflective plate may be disposed at one side or both sides of the two or more solar cell panels facing each other in a direction crossing a virtual center line between the two or more solar cell panels facing each other.

In the third or fourth aspect of the present invention, the solar cell module may further include a reflective plate provided on one or both of two edges of two or more solar cell panels arranged in series in a direction parallel to the virtual center line.

In the fourth aspect of the present invention, the predetermined angle may be greater than 0 ° and less than 180 °.

In the fourth aspect of the present invention, in the two or more solar cell panels, one ends of two adjacent solar cell panels may be connected by a connection shaft, and the reflection plates arranged in a direction crossing the virtual center line may contact each other at the connection shaft or be spaced apart from each other by a predetermined distance.

In the third or fourth aspect of the present invention, the two or more solar panels may include a support configured to support the reflector panel.

In the third or fourth aspect of the present invention, the two or more solar cell panels may be connected in the form of an or v, and when the two or more solar cell panels connected in the form of an or v are arranged such that one of an a and a v is continuously arranged or both of the a and v are mixed, the sunlight incident surfaces may face each other.

In the third or fourth aspect of the present invention, the reflective plate may be additionally provided on the portions connected in the form of a or a v.

In the third or fourth aspect of the present invention, the reflection plate may have a shape of one of a flat surface, a curved surface, or a combination thereof.

In the third or fourth aspect of the present invention, the solar cell module may further include an angle adjusting unit configured to adjust an inclination of the reflection plate.

Detailed Description

Hereinafter, the configuration and effects of the embodiments of the present invention will be described with reference to the drawings.

In the following detailed description, detailed descriptions related to well-known functions or configurations will be excluded so as not to unnecessarily obscure the subject matter of the present invention. Further, when described as including (or containing or having) some elements, it is to be understood that it may include (or contain or have) only those elements, or it may include (or contain or have) other elements as well as those elements, if not specifically limited.

[ first embodiment ]

Fig. 1 is a schematic view of a solar cell module according to a first embodiment of the present invention, and fig. 2 is a view for explaining a change in angle of a reflective plate in the solar cell module according to the first embodiment of the present invention.

Referring to fig. 1 and 2, a solar cell module according to a first embodiment of the present invention includes a solar cell panel 100 having a rectangular shape, first and second reflection plates 210 and 220 respectively disposed on both edges of the solar cell panel 100, and an angle adjusting device 300 adjusting and fixing an angle of each of the first and second reflection plates 210 and 220 with respect to the solar cell panel 100.

The angles α 1 and α 2 between the solar cell panel 100 and each of the first and second reflection plates 210 and 220 may vary, and the variable angle may range from 60 ° to 180 °.

The angle adjusting means 300 may be manually or automatically moved and has a rotating hinge structure. In addition, friction may be applied to fix at a desired angle. Although the angle adjustment and the fixing are performed only by the hinge structure in fig. 1, a separate fixing structure may be provided in addition to the hinge structure.

As shown in fig. 2, on one side of each of the folded solar cell panel 100 and the first and second reflection plates 210 and 220, a width d2 of each of the first and second reflection plates 210 and 220 may be greater than a width d1 of the solar cell panel 100 to increase the incident amount of sunlight.

[ second embodiment ]

Fig. 3 is a schematic view illustrating a solar cell module according to a second embodiment of the present invention.

Referring to fig. 3, the solar cell module according to the second embodiment of the present invention includes third and fourth reflection plates 230 and 240 respectively mounted on upper and lower portions of the solar cell panel 100, in addition to first and second reflection plates 210 and 220 respectively disposed at both sides of the solar cell panel 100. The third and fourth reflection plates 230 and 240 may be varied with respect to the solar cell panel 100. Although the reflection plate is installed on all of the upper and lower portions in fig. 3, the reflection plate may be installed on only one of the upper and lower portions.

During solar power generation, the angle of each of the third and fourth reflection plates 230 and 240 with respect to the solar cell panel 100 may be continuously maintained at 120 °. Although the shadow caused by the sunlight is not generated when the angles α 3 and α 4 of the third and fourth reflection plates 230 and 240 are not acute angles, it is preferable to maintain an angle of 120 ° to increase the incidence area of the sunlight and increase the incidence of the sunlight to the solar cell panel 100 by reflection.

[ third embodiment ]

The solar cell module further includes an illuminance sensor for measuring photosensitivity, and each of the reflection plates 210 and 220 is connected with a rotation motor (not shown) to rotate with respect to the solar cell panel 100, thereby applying a signal of the illuminance sensor, and the reflection plates 210 and 220 are rotated by an electric signal. Here, the rotation motor may be adjusted such that its drive shaft is mechanically connected to the reflection plates 210 and 220, and applied to, for example, a configuration according to the twelfth embodiment or the thirteenth embodiment below.

[ fourth embodiment ]

After solar power generation was performed by using the solar cell module according to the first embodiment of the present invention, power generation efficiency was evaluated as follows.

The solar cell panel 100 is disposed to face south, the angles α 1 and α 2 between the top surface of each of the first and second reflection plates 210 and 220 and the top surface of the solar cell panel 100 are maintained at 180 ° before 10 o 'clock, the angle between the top surface of each of the first and second reflection plates 210 and 220 and the top surface of the solar cell panel 100 is maintained at 120 ° from 10 o' clock to 14 o 'clock, and the angle between the top surface of each reflection plate and the top surface of the solar cell panel is maintained at 180 ° after 14 o' clock.

[ fifth embodiment ]

The solar cell panel 100 is arranged to face the south side, an angle between the first reflection plate 210 disposed at the east side (E) of the reflection plates and the top surface of the solar cell panel 100 is maintained at 180 ° before 10 o ' clock, an angle between the second reflection plate 220 disposed at the west side (W) of the reflection plates and the top surface of the solar cell panel 100 is maintained at 120 °, an angle between the top surface of each of the first reflection plate 210 and the second reflection plate 220 and the top surface of the solar cell panel 100 is maintained at 120 ° from 10 o ' clock to 14 o ' clock, an angle between the first reflection plate of the reflection plates and the top surface of the solar cell panel 100 is maintained at 120 ° after 14 o ' clock, and an angle between the second reflection plate of the reflection plates and the top surface of the solar cell panel is maintained at 180 ° after 14 o ' clock. A method for changing the angle of the reflective plate is described in fig. 4. As shown in (a) of fig. 4, since the first reflection plate 210 is completely unfolded before 10 o' clock and allows the second reflection plate to maintain the angle α 2 at 120 °, solar power generation is performed by maintaining the angle α 1 at 180 °. Thereafter, the solar power generation may be performed by maintaining all the angles α 1 and α 2 from 10 o 'clock to 14 o' clock (i.e., the time when the sun is southward as shown in (b) of fig. 4) at 120 ° and allowing the first reflection plate 210 to maintain the angle α 1 of 120 ° and the second reflection plate 220 to have the fully spread angle α 2 of 180 ° as shown in (c) of fig. 4.

[ sixth embodiment ]

For each time, the angles α 1 and α 2 of the first and second reflection plates 210 and 220 are adjusted before 9:30, after 9:30, 11:30, 13:30, and 13: 30. The angle α 1 between the first reflection plate 210 and the top surface of the solar cell panel 100 is maintained at 180 ° before 9:30, at 140 ° from 9:30 to 11:30, at 100 ° from 11:30 to 13:30, and at 100 ° after 13: 30.

A method for changing the angle of the reflective plate is shown for each step in fig. 5. An angle between the first reflection plate and the second reflection plate before 9:30 is shown in (a) of fig. 5, an angle from 9:30 to 11:30 is shown in (b) of fig. 5, an angle from 11:30 to 13:30 is shown in (c) of fig. 5, and an angle after 13:30 is shown in (d) of fig. 5.

[ seventh embodiment ]

In a state where the internal angle α 5 between the first and second reflection plates 210 and 220 is maintained to be 60 ° by using the solar cell module according to the third embodiment, the first and second reflection plates 210 and 220 are rotated to have the maximum illuminance according to the movement of the solar path. This is shown in fig. 6. That is, the inner angle α 5 between the first reflection plate 210 and the second reflection plate 220 is maintained at 60 °, while the angle α 1 between the first reflection plate 210 and the solar cell panel 110 and the angle α 2 between the second reflection plate 220 and the solar cell panel 110 are changed to be different from each other according to the change of the solar energy path as in fig. 6 (a) to 6 (d).

[ first comparative example ]

In order to compare with embodiments 4 to 7 of the present invention, in a state where the reflection plate is not mounted on the solar cell panel, solar power generation is performed under the same environment as the present invention.

[ second comparative example ]

In the second comparative example, by using the solar cell module according to the first embodiment, power generation is performed in a state where the angle between the top surface of each of the first and second reflection plates 210 and 220 and the top surface of the solar cell panel 100 is fixed to 120 ° regardless of the solar path.

Results obtained after performing solar photovoltaic power generation according to each of embodiment 4 to embodiment 7 and comparative examples 1 and 2 are shown in table 1 below. In table 1 below, the increase rate (%) indicates an increased amount of power generation compared to comparative example 1 in which the reflective plate is not mounted on the solar cell panel.

[ Table 1]

As shown in table 1 above, it is understood that the amount of power generation in embodiments 3 to 7 in which the angle of the reflector is changed according to the change of the solar path is increased as compared with comparative example 2 in which the reflector is not attached or the angle of the reflector is fixed. In particular, it is known that the amount of power generation of embodiment 7 in which the angle of the reflection plate is changed a plurality of times is significantly increased so that the sunlight has the maximum illuminance.

[ eighth embodiment ]

Fig. 7 is a plan view and a side view of a solar cell module according to an eighth embodiment of the present invention, fig. 8 is a perspective view of the solar cell module according to the eighth embodiment of the present invention, fig. 9 is a view exemplarily showing a shape of a reflection plate attached to the solar cell module, and fig. 10 is a view showing a state in which the solar cell module according to the eighth embodiment of the present invention is mounted on a structure such as a fence.

As shown in fig. 7 to 10, a solar cell module 10 according to an eighth embodiment of the present invention includes a plurality of solar cell panels 11, a reflective plate 12, and a support 13.

The plurality of solar cell panels 11 are arranged to face each other such that an internal angle between the sunlight incident surface of one panel and the sunlight incident surface of another panel adjacent thereto forms a predetermined angle (about 90 ° in the drawing).

Further, as shown in fig. 8, each solar cell panel 11 is fixed to the support 13 by a connecting member 14 extending in a longitudinal direction thereof while forming a predetermined angle by a method such as welding or bolting.

Although the angle between the solar panels 11 is set to about 90 ° in the eighth embodiment of the present invention, the angle (θ 1) between the adjacent solar panels 11 may be adjusted in a range of more than 0 ° and less than 180 °.

In addition, the connection member 14 may physically connect the solar cell panel 11 while allowing the solar cell panel 11 to be bent. For example, a mechanical rotation unit, such as a hinge for mechanical connection in a bendable state, may be used. As another example, there is provided a method for connecting solar cell panels 11 in a bendable manner by disposing a flexible member such as plastic or fiber between adjacent solar cell panels 11 and then attaching ends by using a unit such as an adhesive, a bolt and nut, and Velcro (Velcro). Further, an electric wire for connecting electric power generated from the solar cell panel 11 may be provided in the connection member 14.

Further, by a method of fixing the shaft and the solar cell panel 11 to the shaft in a rotatable manner using the connection member 14 and then adjusting the angle of the rotatably connected solar cell panel 11 by a driving unit such as a motor, the angle between the solar cell panels 11 can be controlled by an electric signal.

The reflection plate 12 is fixed to be inclined at a predetermined angle with respect to the support 13 in a state of being in contact with or spaced apart from one end of the solar cell panel 11 by a predetermined distance so as to cross a center line (virtual center line) between the solar cell panels 11 facing each other. The reflecting plate 12 inclined as described above reflects the incident sunlight toward the solar cell panel 11 to improve the power generation efficiency of the solar cell panel 11.

The reflective surface as the surface of the reflective plate 12 may include a metal mirror, a glass mirror, or a plastic mirror to easily reflect sunlight. Alternatively, the reflective surface of the reflective plate 12 may be a transparent flat plate, such as acryl or glass, on which a reflective material is formed in a predetermined pattern.

The pattern of reflective material may be formed on the transparent substrate by using a coating method such as deposition using vacuum deposition or screen printing. Further, a method of attaching a metal foil to a transparent substrate may be applied.

Here, since the substrate of the reflection plate 12 has thermal resistance, an insulating material capable of restricting temperature rise can be used.

Also, a plurality of holes having various shapes may be formed in the reflection plate 12 and allow wind to flow therethrough, thereby reducing pressure applied to the panel and the reflection plate, thereby reducing the risk of damage of the solar cell module caused by strong wind.

As shown in fig. 9 (a) and 9 (b), the shape of the reflection plate 12 may be formed of a flat plate, a curved surface having a predetermined curvature, a plurality of curved surfaces, or a combination thereof.

[ twelfth embodiment ]

Fig. 16 is a side view showing a solar cell module according to a twelfth embodiment of the present invention.

As shown in fig. 16, the solar cell module 50 according to the twelfth embodiment of the present invention allows the installation angle of the reflective plate 12 in the solar cell module according to the eighth embodiment of the present invention to be adjusted by using a motor.

The solar cell module 50 according to the twelfth embodiment of the present invention includes a plurality of solar cell panels 51, a reflection plate 52, a support 53 for supporting the solar cell panels 51, a connection member 54 of the solar cell panels, and an angle adjusting unit 55 for adjusting an angle of the reflection plate 52.

In the solar cell module 50 according to the twelfth embodiment of the present invention, unlike the first embodiment, the reflection plate 52 is not fixed to the support 53 to adjust the angle.

Also, the angle adjusting unit 55 includes a motor 55a fixed to one side of the support 53, a plate-shaped first angle adjusting member 55b rotatably connected to the motor 55a, and a second angle adjusting member 55c fixed to the first angle adjusting member 55b to form a predetermined angle and determine a bottom tilt angle of the reflection plate 52.

As shown in fig. 17, the inclination of the reflection plate 52 with respect to the solar cell panel 51 may be changed as the first angle adjusting member 55b increases or decreases the angle by the operation of the motor 55 a.

Thus, the optimum state can be maintained by adjusting the amount of light incident on the solar cell panel 51 through the reflective plate 52 and adjusting the inclination of the reflective plate 52 in consideration of the solar height. Here, the motor 55a may be controlled in a wired or wireless manner by using a computer including a calculation unit and a storage unit. When wireless control is required, the motor may be provided with a receiving unit capable of wirelessly receiving a control signal. When the motor 55a is operated by providing a control signal for each predetermined time based on at least one piece of information selected from the sun height, sunrise time, and sunset time stored in the storage unit, the reflection plate 52 may be adjusted to have an optimized inclination state in the corresponding time zone.

Although the solar cell module 50 according to the twelfth embodiment of the present invention has a structure in which the angle between the reflection plates 52 is increased or decreased by the motor 51, the angle may be adjusted instead of the angle between the reflection plates 52 by a method of controlling the inclination by rotating the two first angle adjusting members 55b for fixing the reflection plates in one direction.
