[0034] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-11 A photovoltaic module 100 according to an embodiment of the present invention is described. The photovoltaic module 100 includes: a photovoltaic laminate 10, a frame 20, and a junction box 23.

[0035] Specifically, such as Figure 1 , Figure 8 , Figure 9 and Figure 11As shown, the frame 20 surrounds the outer periphery of the photovoltaic laminate 10. The frame 20 includes a short frame 21 and a long frame 22. The short frame 21 includes a first short frame 211 and a second short frame 212 arranged opposite to each other. The long frame 22 includes a first long frame 221 and a second long frame 222 arranged opposite to each other. The first short frame 211 and the second short frame 212 are respectively located at the two ends of the first long frame 221 and the second long frame 222. The junction box 23 is located on the back of the photovoltaic laminate 10. Along the length direction of the frame 20, the junction box 23 is located adjacent to the first short frame 211. One end of the lead cable 24 of the junction box 23 is directed toward the second short frame 212, the first long frame 221, or the second long frame 222.

[0036] The photovoltaic laminate 10 is the core carrier for photoelectric conversion of the photovoltaic module 100. The frame 20 is disposed on the outer periphery of the photovoltaic laminate 10, thereby supporting and protecting the photovoltaic laminate 10. In this application, the frame 20 includes a short frame 21 extending along the width direction of the photovoltaic module 100 and a long frame 22 extending along the length direction of the photovoltaic module 100. The width direction of the photovoltaic module 100 is the length direction of the short frame 21, and the length direction of the photovoltaic module 100 is the length direction of the long frame 22. The short frame 21 includes a first short frame 211 and a second short frame 212, which are arranged opposite to each other along the length direction of the photovoltaic module 100. The long frame 22 includes a first long frame 221 and a second long frame 222, which are arranged opposite to each other along the width direction of the photovoltaic module 100. The two ends of the first short frame 211 and the second short frame 212 are respectively connected to the two ends of the first long frame 221 and the second long frame 222. Junction box 23 is disposed on the back side of photovoltaic laminate 10 along the thickness direction of photovoltaic module 100, and junction box 23 is disposed adjacent to the first short frame 211 along the length direction of photovoltaic module 100. Junction box 23 has lead-out end 231, which is suitable for leading out cable 24. The direction of lead-out end 231 is the lead-out direction of cable 24. Lead-out end 231 can be disposed along the length direction of photovoltaic module 100 toward the second short frame 212, along the width direction of photovoltaic module 100 toward the first long frame 221, or along the width direction of photovoltaic module 100 toward the second long frame 222.

[0037] According to the photovoltaic module 100 of the present invention, by setting the junction box 23 adjacent to the first short frame 211 and setting one end of the lead cable 24 of the junction box 23 toward the second short frame 212, the first long frame 221 or the second long frame 222, that is, setting one end of the lead cable 24 of the junction box 23 not toward the adjacent first short frame 211, the distance between the cable 24 and the first short frame 211 of the adjacent junction box 23 can be avoided, thereby avoiding interference between the cable 24 and the first short frame 211, facilitating the installation of the junction box 23, and shortening the setting length of the jumper 14 between the short frame 21 and the junction box 23 in the following text, thereby effectively reducing power loss and improving the reliability of the photovoltaic module 100.

[0038] Optionally, in this application, the photovoltaic module 100 is a multi-cell photovoltaic module.

[0039] According to some embodiments of the present invention, such as Figure 8 As shown, one end of the lead cable 24 of the junction box 23 faces the long frame 22, and the cable 24 and the junction box 23 are arranged along the length of the short frame 21. The lead end 231 of the junction box 23 is located at the end of the junction box 23 facing the adjacent long frame 22 along the width direction of the photovoltaic module 100, so that one end of the cable 24 is connected to the lead end 231 of the junction box 23, and the other end of the cable 24 is led out along the width direction of the photovoltaic module 100 towards the adjacent long frame 22. The cable 24 and the junction box 23 are arranged along the width direction of the photovoltaic module 100.

[0040] Therefore, by designing one end of the lead cable 24 of the junction box 23 to face the long frame 22, the distance between the cable 24 and the first short frame 211 of the adjacent junction box 23 can be effectively avoided, thereby avoiding interference between the cable 24 and the first short frame 211, facilitating the installation of the junction box 23, improving the installation efficiency of the photovoltaic module 100, and shortening the length of the jumper 14 to reduce power loss.

[0041] Optionally, combined Figure 11 One end of the lead cable 24 of the junction box 23 faces the second short frame 212, and the cable 24 is located on the side of the junction box 23 away from the first short frame 211. The lead end 231 of the junction box 23 is located at the end of the junction box 23 away from the first short frame 211 along the length direction of the photovoltaic module 100, so that one end of the cable 24 is connected to the lead end 231 of the junction box 23, and the other end of the cable 24 is led out towards the second short frame 212 along the length direction of the photovoltaic module 100. The cable 24 and the junction box 23 are arranged along the length direction of the photovoltaic module 100.

[0042] Therefore, by designing the cable 24 to be located on the side of the junction box 23 away from the first short frame 211, interference between the cable 24 and the first short frame 211 can be effectively avoided, which facilitates the installation of the junction box 23, improves the installation efficiency of the photovoltaic module 100, and at the same time shortens the length of the jumper 14, reducing power loss.

[0043] According to some embodiments of the present invention, such as Figure 1 , Figures 7-11 As shown, the photovoltaic laminate 10 includes: a battery cell 11, a first busbar 12 and a second busbar 13, and a jumper 14. The first busbar 12 and the second busbar 13 are respectively connected to the two ends of the battery cell 11. The jumper 14 includes a conductive jumper segment 15 and a non-conductive jumper segment 16. The ends of the conductive jumper segment 15 and the non-conductive jumper segment 16 that are far from each other are respectively connected to the first busbar 12 and the second busbar 13. The ends of the conductive jumper segment 15 and the non-conductive jumper segment 16 that are adjacent to each other are connected to the junction box 23. The length of the conductive jumper segment 15 is less than the length of the non-conductive jumper segment 16. The conductive jumper segment 15 is located between the junction box 23 and the adjacent short frame 21.

[0044] In this application, the battery cell 11 extends along the length of the photovoltaic module 100. The first busbar 12 and the second busbar 13 are respectively connected to the two ends of the battery cell 11 along the length of the photovoltaic module 100. The first busbar 12 is disposed near the first short frame 211, and the second busbar 13 is disposed near the second short frame 212. The conductive jumper segment 15 and the non-conductive jumper segment 16 are arranged along the length of the photovoltaic module 100. The end of the conductive jumper segment 15 away from the non-conductive jumper segment 16 is connected to the first busbar 12, and the end of the non-conductive jumper segment 16 away from the conductive jumper segment 15 is connected to the second busbar 13. The ends of the conductive jumper segment 15 and the non-conductive jumper segment 16 that are adjacent to each other are respectively connected to the junction box 23. The conductive jumper segment 15 is located between the junction box 23 and the adjacent first short frame 211.

[0045] Therefore, by designing the length of the conductive jumper segment 15 to be less than the length of the non-conductive jumper segment 16, and by placing the conductive jumper segment 15 between the junction box 23 and the adjacent short frame 21, the length of the conductive jumper segment 15 can be shortened, thereby reducing the power loss on the conductive jumper segment 15 and increasing the output power of the photovoltaic module 100. At the same time, it is convenient to conduct the current collected on the first busbar 12.

[0046] In this application, the photovoltaic laminate 10 includes two jumpers 14, which are symmetrically arranged along the length of the photovoltaic module 100. The photovoltaic module 100 includes two junction boxes 23. The adjacent ends of the conductive jumper segments 15 and the non-conductive jumper segments 16 in the two jumpers 14 are respectively connected to the corresponding junction boxes 23.

[0047] Optionally, when the battery cells 11 in the photovoltaic module 100 are working normally, the current does not flow through the non-conductive jumper segment 16. When some battery cells 11 fail or are shaded, the current forms a bypass loop through the non-conductive jumper segment 16, bypassing the area where the failure or shading occurs, ensuring the normal collection of current in other areas and improving the reliability of the photovoltaic module 100.

[0048] According to some embodiments of the present invention, such as Figures 2-6 , Figure 9 As shown, the conductive jumper segment 15 includes: a first connecting segment 151, a second connecting segment 152, and a third connecting segment 153. One end of the first connecting segment 151 is electrically connected to the first busbar 12; one end of the second connecting segment 152 is connected to the other end of the first connecting segment 151, and the second connecting segment 152 and the first connecting segment 151 extend in different directions; one end of the third connecting segment 153 is connected to the other end of the second connecting segment 152, and the other end of the third connecting segment 153 is connected to the junction box 23.

[0049] One end of the first connecting segment 151 is connected to the first busbar 12, the other end of the first connecting segment 151 is connected to one end of the second connecting segment 152, the other end of the second connecting segment 152 is connected to one end of the third connecting segment 153, and the other end of the third connecting segment 153 is connected into the junction box 23. The extension directions of the first connecting segment 151, the second connecting segment 152, and the third connecting segment 153 are different from each other.

[0050] Therefore, by designing the conductive jumper segment 15, which includes the first connecting segment 151, the second connecting segment 152, and the third connecting segment 153, the structure of the conductive jumper segment 15 is optimized, the installation direction of the junction box 23 is changed, and the setting position of the lead-out end 231 of the junction box 23 is changed, thereby changing the lead-out direction of the cable 24, avoiding interference between the cable 24 and the adjacent short frame 21, facilitating the setting of the junction box 23 and the cable 24, and improving the installation efficiency of the photovoltaic module 100.

[0051] According to some embodiments of the present invention, such as Figure 2 As shown, the included angle between the first connecting segment 151 and the second connecting segment 152 is α, and α satisfies: 30°≤α≤150°.

[0052] When the angle between the first connecting segment 151 and the second connecting segment 152 is less than 30°, the angle is too small, which may cause the distance between the lead-out end 231 of the junction box 23 and the first short frame 211 to be too close, resulting in interference between the cable 24 and the first short frame 211. When the angle between the first connecting segment 151 and the second connecting segment 152 is greater than 150°, the angle is too large, which may cause the length of the conductive jumper segment 15 to be too long, resulting in greater power loss. For example, α can be 30°, 45°, 60°, 90°, or 120°.

[0053] Therefore, by limiting the angle range between the first connecting segment 151 and the second connecting segment 152, the distance between the lead-out end 231 of the junction box 23 and the first short frame 211 can be avoided from being too close, thereby avoiding interference between the cable 24 and the first short frame 211, facilitating the installation of the junction box 23, and at the same time avoiding the conductor jumper segment 15 from being too long, thus reducing power loss.

[0054] According to some embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the first connecting segment 151, the second connecting segment 152, and the third connecting segment 153 are perpendicular to each other.

[0055] In this application, the first connecting segment 151 extends along the length of the photovoltaic module 100, the second connecting segment 152 extends along the width of the photovoltaic module 100, and the third connecting segment 153 extends along the thickness of the photovoltaic module 100. The angle between the first connecting segment 151 and the second connecting segment 152 is 90°, and the angle between the second connecting segment 152 and the third connecting segment 153 is also 90°. Therefore, by designing the first connecting segment 151, the second connecting segment 152, and the third connecting segment 153 to be perpendicular and orthogonal to each other, the distance between the lead-out end 231 of the junction box 23 and the first short frame 211 can be avoided from being too close, preventing interference between the cable 24 and the first short frame 211. At the same time, it improves the overall structural strength and reliability of the conductive jumper segment 15, facilitates the quick connection of the third connecting segment 153 into the junction box 23 without the need for an additional adapter structure, and facilitates the installation of the junction box 23.

[0056] According to some embodiments of the present invention, such as Figure 5 and Figure 6 As shown, the first connecting segment 151, the second connecting segment 152 and the third connecting segment 153 are integrally formed parts. The first connecting segment 151 and the second connecting segment 152 are located in the same plane, and the third connecting segment 153 is formed by bending the other end of the second connecting segment 152.

[0057] The first connecting segment 151, the second connecting segment 152, and the third connecting segment 153 are manufactured as a whole. In the thickness direction of the photovoltaic module 100, the surfaces of the first connecting segment 151 and the second connecting segment 152 away from the battery cell 11 are flush with each other, that is, the first connecting segment 151 and the second connecting segment 152 have no overlapping area in the thickness direction of the photovoltaic module 100. The other end of the second connecting segment 152 away from the first connecting segment 151 is bent along the thickness direction of the photovoltaic module 100 to form the third connecting segment 153.

[0058] Therefore, by designing the first connecting segment 151, the second connecting segment 152, and the third connecting segment 153 as an integrally formed part, the height of the connection point between the first connecting segment 151 and the second connecting segment 152 in the thickness direction of the photovoltaic module 100 can be reduced. This reduces the risk of breakage during lamination and also reduces the risk of breakage failure of the conductive jumper segment 15, extending the service life of the conductive jumper segment 15. At the same time, it improves the structural strength and integrity of the conductive jumper segment 15, increases the processing efficiency of the conductive jumper segment 15, and improves the reliability of the photovoltaic module 100.

[0059] Optionally, the conductive jumper segment 15 is a multi-segment "L"-shaped structure formed by repeatedly bending a "I"-shaped conductive metal.

[0060] Optionally, such as Figure 3 and Figure 4 As shown, the first connecting segment 151 and the second connecting segment 152 are separate components. The other end of the first connecting segment 151 and one end of the second connecting segment 152 are stacked along the thickness direction of the photovoltaic laminate 10. That is, the first connecting segment 151 and the second connecting segment 152 are two independent components, and the adjacent ends of the first connecting segment 151 and the second connecting segment 152 have an overlapping area in the thickness direction of the photovoltaic module 100. Therefore, by designing the first connecting segment 151 and the second connecting segment 152 as separate components and partially stacked, the processing difficulty of the conductive jumper segment 15 can be reduced, the processing flexibility of the conductive jumper segment 15 can be improved, and the processing cost can be reduced.

[0061] Optionally, the first connecting segment 151 and the second connecting segment 152 are separate components, with one end of the first connecting segment 151 adjacent to and connected to one end of the second connecting segment 152. That is, the first connecting segment 151 and the second connecting segment 152 are two independent components, with their adjacent ends connected to each other, and there is no overlap in the thickness direction of the photovoltaic module 100. This reduces the processing difficulty of the conductive jumper segment 15, and also reduces the risk of breakage during lamination, improving the reliability of the photovoltaic module 100.

[0062] According to some embodiments of the present invention, such as Figure 7As shown, one end of the non-conductive jumper segment 16 adjacent to the conductive jumper segment 15 has the same structure as the conductive jumper segment 15, and one end of the non-conductive jumper segment 16 adjacent to the conductive jumper segment 15 is opposite to the conductive jumper segment 15 along the length direction of the short frame 21.

[0063] The non-conductive jumper segment 16 has the same structure as the conductive jumper segment 15 at one end along the length direction of the photovoltaic module 100. That is, the non-conductive jumper segment 16 at one end adjacent to the conductive jumper segment 15 includes a first connecting segment 151, a second connecting segment 152, and a third connecting segment 153. In the width direction of the photovoltaic module 100, the second connecting segment 152 and the third connecting segment 153 in the non-conductive jumper segment 16 are arranged opposite to the second connecting segment 152 and the third connecting segment 153 in the conductive jumper segment 15.

[0064] Therefore, by designing one end of the non-conductive jumper segment 16 adjacent to the conductive jumper segment 15 opposite to the conductive jumper segment 15 along the length direction of the short frame 21, the junction box 23 is set along the width direction of the photovoltaic module 100, which facilitates the lead-out end 231 of the junction box 23 to be set towards the adjacent long frame 22, and facilitates the cable 24 to be led out along the width direction of the photovoltaic module 100 towards the adjacent long frame 22, effectively avoiding interference between the cable 24 and the first short frame 211, and facilitating the installation of the junction box 23.

[0065] According to some embodiments of the present invention, the conductive jumper segment 15 includes: a first connecting segment 151, a second connecting segment 152, a third connecting segment 153, and a fourth connecting segment. One end of the first connecting segment 151 is electrically connected to the first busbar 12. One end of the second connecting segment 152 is connected to the other end of the first connecting segment 151, and the second connecting segment 152 and the first connecting segment 151 extend in different directions. One end of the third connecting segment 153 is connected to the other end of the second connecting segment 152, and the other end of the third connecting segment 153 extends toward the side where the first busbar 12 is located. One end of the fourth connecting segment is connected to the other end of the third connecting segment 153, and the other end of the fourth connecting segment is connected into the junction box 23.

[0066] One end of the first connecting segment 151 is connected to the first busbar 12. The other end of the first connecting segment 151 extends along the length of the photovoltaic module 100 in a direction away from the first short frame 211 and connects to one end of the second connecting segment 152. The other end of the second connecting segment 152 extends along the width of the photovoltaic module 100 in a direction away from the adjacent long frame 22 and connects to one end of the third connecting segment 153. The other end of the third connecting segment 153 extends along the length of the photovoltaic module 100 in a direction away from the first short frame 211 and connects to the fourth connecting segment. The other end of the fourth connecting segment extends along the thickness of the photovoltaic module 100 and enters the junction box 23. The extension directions of the first connecting segment 151 and the second connecting segment 152 are perpendicular to each other, the extension directions of the first connecting segment 151 and the third connecting segment 153 are the same, and the fourth connecting segment is perpendicular to both the extension directions of the first connecting segment 151 and the second connecting segment 152.

[0067] Therefore, by designing the conductive jumper segment 15, which includes the first connecting segment 151, the second connecting segment 152, the third connecting segment 153, and the fourth connecting segment, the structure of the conductive jumper segment 15 is optimized, the installation direction of the junction box 23 is changed, the setting position of the lead-out end 231 of the junction box 23 is changed, thereby changing the lead-out direction of the cable 24, avoiding interference between the cable 24 and the adjacent short frame 21, facilitating the setting of the junction box 23 and the cable 24, and improving the installation efficiency of the photovoltaic module 100.

[0068] According to some embodiments of the present invention, such as Figure 10 As shown, one end of the non-conductive jumper segment 16 adjacent to the conductive jumper segment 15 has the same structure as the conductive jumper segment 15, and one end of the non-conductive jumper segment 16 adjacent to the conductive jumper segment 15 is opposite to the fourth connecting segment of the conductive jumper segment 15 along the length direction of the long frame 22.

[0069] The non-conductive jumper segment 16 has the same structure as the conductive jumper segment 15 at one end adjacent to the conductive jumper segment 15 along the length direction of the photovoltaic module 100. That is, the non-conductive jumper segment 16 at one end adjacent to the conductive jumper segment 15 includes a first connecting segment 151, a second connecting segment 152, a third connecting segment 153, and a fourth connecting segment. In the length direction of the photovoltaic module 100, the third connecting segment 153 and the fourth connecting segment in the non-conductive jumper segment 16 are arranged opposite to the third connecting segment 153 and the fourth connecting segment in the conductive jumper segment 15.

[0070] Therefore, by designing one end of the non-conductive jumper segment 16 adjacent to the conductive jumper segment 15 and the fourth connecting segment of the conductive jumper segment 15 opposite each other along the length direction of the long frame 22, the junction box 23 is set along the length direction of the photovoltaic module 100. This facilitates the setting of the lead-out end 231 of the junction box 23 towards the direction away from the adjacent short frame 21, i.e., the first short frame 211. This makes it easier for the cable 24 to be led out from the lead-out end 231 of the junction box 23 in a direction away from the first short frame 211, effectively avoiding interference between the cable 24 and the first short frame 211, facilitating the installation of the junction box 23. At the same time, it shortens the length of the conductive jumper segment 15 and reduces power loss.

[0071] According to some embodiments of the present invention, such as Figure 10 As shown, the distance between one end of the non-conductive jumper segment 16 and the adjacent short frame 21 is A, and the distance between the fourth connecting segment of the conductive jumper segment 15 and the adjacent short frame 21 is B. A and B satisfy: A < B.

[0072] Along the length of the photovoltaic module 100, the distance between the fourth connecting segment of the non-conductive jumper segment 16 and the first short frame 211 is A, and the distance between the fourth connecting segment of the conductive jumper segment 15 and the first short frame 211 is B. A is less than B, that is, the distance between the fourth connecting segment of the non-conductive jumper segment 16 and the first short frame 211 is less than the distance between the fourth connecting segment of the conductive jumper segment 15 and the first short frame 211.

[0073] Therefore, by designing that the distance between one end of the adjacent conductive jumper segment 15 of the non-conductive jumper segment 16 and the adjacent short frame 21 is less than the distance between the fourth connecting segment of the conductive jumper segment 15 and the adjacent short frame 21, it is convenient for the third connecting segment 153 and the fourth connecting segment in the non-conductive jumper segment 16 to be arranged opposite to the third connecting segment 153 and the fourth connecting segment in the conductive jumper segment 15. This facilitates the arrangement of the junction box 23 along the length direction of the photovoltaic module 100, allowing the cable 24 to be led out from the lead-out end 231 of the junction box 23 along the length direction of the photovoltaic module 100 in a direction away from the first short frame 211, avoiding interference between the cable 24 and the first short frame 211, and facilitating the installation of the junction box 23.
