Summary of the Invention [Problem to be solved by the invention]

[0003] SUMMARY OF THE INVENTION Embodiments of the present application provide a curved solar panel, a solar power generation array and a solar power generation system to solve at least one of the technical problems existing above. [Means for solving the problem]

[0004] A first aspect of the present application provides a curved solar panel. The curved solar panel includes wave peaks and wave valleys connected sequentially in a first direction. The curved solar panel further includes a power generating region where a power generating layer is provided, a first non-power generating region, and a second non-power generating region. The first non-power generating region and the second non-power generating region are located on opposite sides of the power generating region in the first direction, respectively. The upper portion of the first non-power generating region is used to overlap and connect to the second non-power generating region of an adjacent curved solar panel. The width of the first non-power generating region in the first direction is defined as X1. The width of the second non-power generating region in the first direction is defined as X2. The thickness of the curved solar panel is defined as W, and X1, X2, and W satisfy the relationship X1≧X2+W.

The third non-power-generating region and the fourth non-power-generating region are located on opposite sides of the power-generating region in a second direction, which is different from the first direction. The first non-power-generating region, the third non-power-generating region, the second non-power-generating region, and the fourth non-power-generating region are sequentially connected to surround the power-generating region. Along the second direction, the third non-power-generating region of each curved solar panel is overlapped and connected to the fourth non-power-generating region of an adjacent curved solar panel to form a second overlapping connection. The overlapping connection width along the second direction of the second overlapping connection portion of any two adjacent curved solar panels is defined as H1.

[0020] The following describes in detail the embodiments of the present application. Examples according to the embodiments are shown in the drawings, and the same or similar reference numerals throughout refer to the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are illustrative and are not to be construed as limiting the present application.

[0021] The following disclosure provides many different embodiments or examples for realizing different structures of the present application. To simplify the disclosure of the present application, specific example components and configurations are described below. Of course, these are merely examples and are not intended to limit the present application. Although the present application may repeat reference numerals and / or characters in different examples, such repetition is for the purpose of simplicity and clarity and does not in itself indicate a relationship between the various embodiments and / or configurations discussed. Although the present application provides examples of various specific processes and materials, those skilled in the art may recognize the application of other processes and / or the use of other materials.

[0022] Since the back surface of the curved solar panel is not flat, when installing it on a roof, it is difficult to ensure that the overlapping connection area of ​​each curved solar panel is consistent with that of the adjacent curved solar panel, and the actual power generation area of ​​each curved solar panel varies. Therefore, when the angle of illumination between the sunlight and the plane of the curved solar panel is at a certain angle due to changes in the sunshine duration, the amount of power generated by each curved solar panel will vary greatly, and ultimately the overall power generation efficiency of the entire solar power generation system will be reduced due to current limitation.

[0023] In the embodiments of the present application, "current limiting" refers to controlling the flow of current by electrical means to protect assemblies in a solar power generation system, improve efficiency, and maintain the stability of the solar power generation system. Specifically, in a solar power generation system, if the power generation efficiency of one solar panel among multiple solar panels connected in series decreases and the output current decreases, the overall output current of the entire solar power generation system will decrease, preventing damage to other assemblies in the solar power generation system (e.g., inverter, controller, etc.) due to excessive current.

[0024] The following describes the technical solutions in the embodiments of the present application in combination with the drawings, and the embodiments described are not all the embodiments but only some of the embodiments of the present application.

[0025] 1, a solar power generation system 100a according to a first embodiment of the present application includes a solar power generation array 10 and an energy storage device 20 electrically connected to the solar power generation array 10. The solar power generation array 10 is used to provide power to the energy storage device 20. The energy storage device 20 stores power generated by the solar power generation array 10 during the daytime so that it can be supplied at night or in a situation where the solar power generation array 10 cannot generate power. The energy storage device 20 may be, for example, but is not limited to, a lithium-ion battery.

[0026] Specifically, the solar power array 10 includes a first solar power assembly 10a, a second solar power assembly 10b, a positive electrode current collecting box 13, and a negative electrode current collecting box 14. The first solar power assembly 10a includes a plurality of curved solar panels 11 and a plurality of voltage and current adjusting units 12. In the first solar power assembly 10a, the curved solar panels 11 and the voltage and current adjusting units 12 are the same in number, and each voltage and current adjusting unit 12 is connected in series to a corresponding curved solar panel 11, and the plurality of voltage and current adjusting units 12 are connected in series to each other. In the first solar power assembly 10a, the positive pole of each curved solar panel 11 and the positive pole of each voltage and current adjusting unit 12 are electrically connected to the positive electrode current collecting box 13, and the negative pole of each curved solar panel 11 and the negative pole of each voltage and current adjusting unit 12 are electrically connected to the negative electrode current collecting box 14.

[0027] The second solar power assembly 10b has a similar configuration to the first solar power assembly 10a. The second solar power assembly 10b includes a plurality of curved solar panels 11 and a plurality of voltage and current adjustment units 12. In the second solar power assembly 10b, the number of curved solar panels 11 and the number of voltage and current adjustment units 12 are the same, and each voltage and current adjustment unit 12 is connected in series to a corresponding curved solar panel 11, and the plurality of voltage and current adjustment units 12 are connected in series to each other. In the second solar power assembly 10b, the positive terminal of each curved solar panel 11 and the positive terminal of each voltage and current adjustment unit 12 are electrically connected to a positive electrode current collecting box 13, and the negative terminal of each curved solar panel 11 and the negative terminal of each voltage and current adjustment unit 12 are electrically connected to a negative electrode current collecting box 14.

[0028] In some embodiments, the voltage and current regulating unit 12 includes a charge controller. The charge controller regulates the voltage and current of the curved solar panel 11 connected in parallel with it, preventing overcharging and over-discharging. The charge controller also prevents the current in the energy storage device 20 from flowing back to the curved solar panel 11 at night or when there is insufficient lighting. Furthermore, the charge controller can employ maximum power point tracking technology to optimize the power conversion from the curved solar panel 11 to the energy storage device 20.

[0029] The positive and negative current collecting boxes 13 and 14 collect the DC input lines of the curved solar panels 11 in the solar power array 10 and then transport the current to the energy storage device 20 via a single line. This simplifies the wiring, reduces the complexity of the wiring connections, and simplifies the installation and maintenance of the solar power generation system 100a. The positive and negative current collecting boxes 13 and 14 may be equipped with fuses or circuit breakers to prevent overcurrent situations. If a problem occurs in a circuit, the fuse will blow, protecting the entire solar power generation system 100a from damage. The positive and negative current collecting boxes 13 and 14 are also waterproof and dustproof, protecting the internal electrical assemblies from harsh environmental conditions and enhancing the safety of the system.

[0030] In some embodiments, all of the curved solar panels 11 in the first solar photovoltaic assembly 10a face the same direction, and all of the curved solar panels 11 in the second solar photovoltaic assembly 10b face the same direction, but the curved solar panels 11 in the first solar photovoltaic assembly 10a and the second solar photovoltaic assembly 10b face different directions. That is, the curved solar panels 11 in the same solar photovoltaic assembly are connected in series and face the same direction, and the curved solar panels 11 in different solar photovoltaic assemblies are connected in parallel and face different directions. The above-mentioned directions may be any of east, west, south, north, southeast, northeast, southwest, northwest, etc.

[0031] As shown in Fig. 2, when the solar power generation system 100a is applied to home power supply, the mounting surfaces S on the roof of the building include a first mounting surface S1 facing east, a second mounting surface S2 facing west, a third mounting surface S3 facing south, and a fourth mounting surface S4 facing north. The first solar power generation assembly 10a and the second solar power generation assembly 10b can be mounted on any two different mounting surfaces S. In the embodiment shown in Fig. 1, the solar power generation array 10 will be described as having two solar power generation assemblies. In other embodiments, the number of solar power generation assemblies in the solar power generation array 10 is not limited to the above.

[0032] 3, the curved solar cell panel 11 includes wave crests 11p and wave troughs 11r connected in sequence along a first direction D1. Specifically, the curved solar cell panel 11 includes a front panel 111, a back panel 112, and a power generation layer 113 sandwiched between the front panel 111 and the back panel 112. The back panel 112, the power generation layer 113, and the front panel 111 are stacked in sequence along a third direction D3. The first direction D1 is perpendicular to the third direction D3.

[0033] For ease of explanation, the first direction D1 is also referred to as the left-right direction, and the third direction D3 is also referred to as the up-down direction. The negative direction of the first direction D1 is the direction from left to right, while the positive direction of the first direction D1 is the direction from bottom to top. The negative direction of the third direction D3 is the direction from bottom to top, while the positive direction of the third direction D3 is the direction from bottom to top.

[0034] More specifically, the curved solar cell panel 11 includes a light-receiving surface 11f and a non-light-receiving surface 11g facing each other. The side where the light-receiving surface 11f is located is used to receive sunlight L. The front panel 111 is located on the side where the light-receiving surface 11f is located and protects the light-receiving surface 11f of the power generation layer 113. The front panel 111 may be, for example, but is not limited to, a light-transmitting curved glass. The back panel 112 is located on the side where the non-light-receiving surface 11g is located and supports and protects the side where the non-light-receiving surface 11g of the power generation layer 113 is located. The back panel 112 may be, for example, but is not limited to, a flexible back panel or curved glass. The power generation layer 113 includes a plurality of battery sheets electrically connected to each other. The curved solar cell panel 11 further includes, for example, but is not limited to, an adhesive film located between the front panel 111 and the power generation layer 113 and an adhesive film located between the back panel 112 and the power generation layer 113.

[0035] The curved solar cell panel 11 includes a power-generating region 11e and a non-power-generating region. The power-generating region 11e is provided with a power-generating layer 113, while the non-power-generating region is not provided with a power-generating layer 113. Specifically, the non-power-generating region includes a first non-power-generating region 11a and a second non-power-generating region 11b. The first non-power-generating region 11a and the second non-power-generating region 11b are located on opposite sides of the power-generating region 11e along the first direction D1. When the curved solar cell panels 11 are installed, the upper portion of the first non-power-generating region 11a of each curved solar cell panel 11 is used to overlap and connect with the second non-power-generating region 11b of the adjacent curved solar cell panel 11 along the first direction D1.

[0036] The width of the first non-power-generating region 11a along the first direction D1 is X1. The width of the second non-power-generating region 11b along the first direction D1 is X2. The thickness of the curved solar cell panel 11 is W, where X1, X2, and W satisfy X1 ≥ X2 + W. Thus, when the curved solar cell panels 11 according to the embodiment of the present application are installed from left to right as shown in FIG. 4 , the width X2 of the second non-power-generating region 11b of the upper curved solar cell panel 11 is smaller than the width X1 of the first non-power-generating region 11a of the lower curved solar cell panel 11 at the overlapping connection position. This is also advantageous in ensuring that the right curved solar cell panel 11 of two adjacent curved solar cell panels 11 in the first direction D1 does not shield the power-generating layer 113 of the left curved solar cell panel 11, thereby not affecting the overall power generation efficiency.

[0037] Furthermore, the upper portion of the first non-power-generating region 11a of each curved solar cell panel 11 is overlapped and connected to the second non-power-generating region 11b of the adjacent curved solar cell panel 11 to form a first overlapping connection. The overlapping connection width along the first direction D1 of the first overlapping connection portion of any two adjacent curved solar cell panels 11 is defined as W1. W1, X1, and X2 satisfy W1 ≥ (X1 + X2) / 2. This advantageously ensures that the power-generating layers 113 at the two ends of the curved solar cell panels 11 in the first direction D1 are not shielded when overlapping along the first direction D1.

[0038] In the embodiment shown in Figures 3 and 4, the curved solar panel 11 includes two crests 11p and two troughs 11r. Along the first direction D1, each crest 11p is connected to one trough 11r in a sequential, alternating manner. Along the first direction D1, one of the two edges of the curved solar panel 11 is a crest 11p and the other is a trough 11r. The first non-power-generating region 11a is located within the trough-shaped edge of the curved solar panel 11, and the second non-power-generating region 11b is located within the crest-shaped edge of the curved solar panel 11. In other words, the first non-power-generating region 11a is located within the trough 11r of the curved solar panel 11, and the second non-power-generating region 11b is located within the crest 11p of the curved solar panel 11. In this way, two adjacent curved solar cell panels 11 are overlappingly connected by engaging with each other in the left-right direction, which is advantageous in increasing the overall structural stability and preventing displacement or damage caused by environmental factors (such as wind and rain).

[0041] The reference included angle is the standard included angle of the solar power generation array 10, and this standard included angle is a constant value in design. The horizontal plane HS is a logical reference plane and is an equipotential surface in the Earth's gravitational field. Since the gravitational potential between any two points on the horizontal plane HS is equal, this means that, in theory, water does not flow on this surface.

[0042] It should be noted that the horizontal plane HS in Figure 5 is merely an example. As can be understood, the horizontal plane HS is not a perfectly flat surface, since the Earth's gravitational field is affected by the non-uniformity of the Earth's own mass distribution.

[0043] In the embodiment shown in Figure 5, each crest 11p and each trough 11r extends along the second direction D2. The first direction D1, the second direction D2, and the third direction D3 are perpendicular to each other. The cross sections of each crest 11p and each trough 11r perpendicular to the second direction D2 are semicircular. The plane on which the centers of the semicircles of each crest 11p and each trough 11r lie defines an imaginary plane VS parallel to the plane on which the first direction D1 and the second direction D2 lie. The measured included angle between the curved solar cell panel 11 and the horizontal plane HS is the included angle between the imaginary plane VS and the horizontal plane HS.

[0044] As shown in Figure 6, the curved solar panel 11 further includes a third non-power-generating region 11c and a fourth non-power-generating region 11d. The third non-power-generating region 11c and the fourth non-power-generating region 11d are located on opposite sides of the power-generating region 11e in the second direction D2, and the first non-power-generating region 11a, the third non-power-generating region 11c, the second non-power-generating region 11b, and the fourth non-power-generating region 11d are sequentially connected to surround the power-generating region 11e. The upper portion of the third non-power-generating region 11c of the curved solar panel 11 is used to overlap and connect to the fourth non-power-generating region 11d of an adjacent curved solar panel 11 in the second direction D2. For ease of illustration, the back panel 112 is omitted from Figure 6.

[0045] As shown in FIG. 7, when mounting a plurality of curved solar cell panels 11 on a mounting surface S of a roof, in a first direction D1, the curved solar cell panels 11 in each row are mounted in order from left to right, and in a second direction D2, the curved solar cell panels 11 in multiple rows are mounted in order from bottom to top, i.e., after mounting the lower row of curved solar cell panels 11, the upper row of curved solar cell panels 11 are mounted.

[0046] Specifically, the upper portion of the third non-power-generating region 11c of each curved solar panel 11 is overlapped and connected to the fourth non-power-generating region 11d of the adjacent curved solar panel 11 to form a second overlapping connection. The overlapping connection width of the second overlapping connection between any two adjacent curved solar panels 11 along the second direction D2 is defined as H1. The width of the third non-power-generating region 11c along the second direction D2 is X3. H1, X3, and the thickness W of the curved solar panel 11 satisfy the relationship H1≦X3+W. In this way, when two adjacent curved solar panels 11 are overlapping and connected in the second direction D2, the upper curved solar panel 11 shields or shades the power-generating layer 113 of the lower curved solar panel 11, which is advantageous in ensuring that the power generation efficiency of the entire solar power generation system 100a is not affected. It should be noted that a certain curved solar cell panel 11 can also prevent localized overheating due to the hot spot phenomenon, which can cause the adhesive film to melt or peel off.

[0047] The installation principle of the solar power generation system 100a according to the embodiment of the present invention will be specifically described below.

[0048] 1. On the same mounting surface S, all the curved solar cell panels 11 are mounted in series connection, and on different mounting surfaces S, all the curved solar cell panels 11 are mounted in parallel connection.

[0049] 2. Each row of curved solar cell panels 11 is installed in a left-to-right order in the first direction D1, and multiple rows of curved solar cell panels 11 are installed in a bottom-to-top order in the second direction D2.

[0050] 3. When installing from left to right, the overlap width of any two adjacent curved solar cell panels 11 along the first direction D1 is W1. The width X1 of the first non-power-generating region 11a and the width X2 of the second non-power-generating region 11b must satisfy W1 ≥ (X1 + X2) / 2 to avoid overlapping with the power-generating layer 113 and shading the battery sheet, which could affect power generation. Because curved solar cell panels are curved, it is difficult to ensure that the widths of the first non-power-generating region 11a and the second non-power-generating region 11b are equal during design. When installing from left to right, if the width of the first non-power-generating region 11a is less than or equal to the width of the second non-power-generating region 11b, the power-generating layer 113 may be shaded. Therefore, it is necessary to further satisfy X1 ≥ X2 + W to avoid shading the battery sheet of the left-side curved solar cell panel 11.

[0051] TIFF2026508754000005.tif33170

[0052] 5. Along the second direction D2, the overlapping width H1 at the overlapping joint of two adjacent curved solar panels 11, the width X3 of the third non-power-generating area 11c, and the thickness W of the curved solar panel 11 must satisfy H1≦X3+W. If not, the position needs to be adjusted. When overlapping and connecting the curved solar panels 11 one above the other, the battery sheet of the lower curved solar panel 11 must be shielded or shaded to avoid affecting the power generation. This can also prevent local overheating due to hot spots in one curved solar panel 11, which can cause the adhesive film to melt or delaminate.

[0053] 6. After installing the curved solar panel 11, if necessary, connect the circuit as shown in Figure 1. When connecting the circuit, the power generating area 11e of the curved solar panel 11 must be shielded to prevent electric shock.

[0054] As described above, the solar power generation system according to the embodiments of the present application solves the problem of local shading when curved solar panels are stacked, which affects the overall power generation efficiency of the solar power generation system, by designing the size of the non-power generating area of ​​the curved solar panel and the thickness of the curved solar panel. In some embodiments, by setting the above mounting principle, in combination with the voltage and current regulating unit, the system efficiency of curved solar panels mounted on the roof can be improved by about 30%.

[0055] 8 , a solar power generation system 100b according to the second embodiment of the present invention is different from the solar power generation system 100a according to the first embodiment in that the solar power generation system 100b further includes a controller 30, one end of which is electrically connected to the solar power generation array 10 and the other end of which is electrically connected to the energy storage device 20 and the power grid 200, respectively. The controller 30 is used to control the solar power generation array 10 to provide power to the energy storage device 20 and / or the power grid 200.

[0056] As can be understood, the above mounting principles of the solar power generation system 100a apply to the solar power generation system 100b as well.

[0057] Specifically, the solar power generation system 100a is an off-grid system and is capable of autonomous operation. That is, the solar power generation system 100a can operate independently without being connected to the public power grid 200. Furthermore, the solar power generation system 100a can automatically manage the process of power generation and storage without requiring human intervention. For example, if the power generated by the curved solar panel 11 in the solar power generation array 10 exceeds the current power consumption of the household, the solar power generation system 100a automatically stores the surplus power in the energy storage device 20. If the power generated by the curved solar panel 11 in the solar power generation array 10 does not meet the demand, the solar power generation system 100a automatically provides power from the energy storage device 20 for household use.

[0058] The solar power generation system 100b is a grid-connected system. The solar power generation system 100b is not only capable of autonomous operation but also capable of transmitting surplus power to the power grid. That is, the solar power generation system 100b is capable of self-sufficiency in power for household loads, and is also capable of transmitting surplus power to the public power grid 200, and the solar power generation system 100b has the potential to contribute power to the power grid 200.

In this specification, general references to such terms do not necessarily refer to the same embodiment or example.
