Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0030] In this application, by using a baffle to cover the frame of the photovoltaic array, the pressure frame component and the connecting component of the edge covering device, the exposure of other components of the photovoltaic array and the edge covering device can be reduced, which is conducive to the integration of the photovoltaic array with the installation environment and makes the overall photovoltaic array more aesthetically pleasing.

[0031] Example 1

[0032] Please see Figure 1 , Figure 2 and Figure 3The shading device 10 of the photovoltaic array 100 in this application embodiment includes a frame pressing component 11, a connecting component 12 and a baffle 13. The frame pressing component 11 is used to be fixedly connected to the frame 20 of the photovoltaic array 100. The connecting component 12 connects the baffle 13 to the frame pressing component 11. The baffle 13 is used to shield the frame pressing component 11, the connecting component 12 and the frame 20.

[0033] The shading device 10 of the photovoltaic array 100 in this embodiment of the application uses a baffle 13 to cover the frame 20 of the photovoltaic array 100, the frame pressing component 11 and the connecting component 12 of the shading device 10. This can reduce the exposure of the photovoltaic array 100 and other components of the shading device 10, which is conducive to the integration of the photovoltaic array 100 with the installation environment and makes the overall photovoltaic array 100 more aesthetically pleasing.

[0034] Specifically, the installation environment is, for example, a building roof. In other embodiments, the installation environment may also be a glass curtain wall, the ground, a water surface, etc.

[0035] In this embodiment, the photovoltaic array 100 includes multiple battery modules, each of which is surrounded by a frame. The frame 20 forms the perimeter of the photovoltaic array 100. In other words, the baffle 13 is used to shield the frame 20 around the photovoltaic array 100, but not the internal frame. This shielding of the frame 20, which is in contact with the installation environment, allows the photovoltaic array 100 to blend better and more aesthetically pleasingly with the environment. At the same time, not shielding the internal frame saves materials and reduces costs and manufacturing complexity.

[0036] In other embodiments, the photovoltaic array 100 may include multiple battery modules, each battery module having a frame around its perimeter, with the frame 20 serving as the frame around some or all of the battery modules. In other words, the baffle 13 is used to shield some or all of the frame 20 around the battery modules; alternatively, the photovoltaic array 100 may consist of a single battery module, with the baffle 13 shielding the frame 20 around that battery module.

[0037] In this embodiment, the baffle 13 completely blocks the frame 20 around the photovoltaic array 100. Thus, the outer frame 20 of the baffle 13 is not exposed, which can completely block the frame 20, making the photovoltaic array 100 more integrated with the installation environment, and making the overall photovoltaic array 100 more aesthetically pleasing.

[0038] In other embodiments, the baffle 13 may partially block the perimeter 20 of the photovoltaic array 100. In other words, a portion of the perimeter 20 of the photovoltaic array 100 is blocked by the baffle 13, while the remaining portion is not blocked by the baffle 13.

[0039] The specific form of the photovoltaic array 100 and the specific way in which the baffle 13 blocks the frame 20 are not specified here.

[0040] Specifically, the frame assembly 11 and the frame 20 can be fixedly connected by welding, bonding, snap-fitting, riveting, threaded connection or other methods. No specific method of fixing the frame assembly 11 and the frame 20 is limited here.

[0041] Specifically, the connecting assembly 12 can connect the baffle 13 to the pressure frame assembly 11 by welding, bonding, snap-fitting, riveting, threaded connection or other means. The specific method by which the connecting assembly 12 connects the baffle 13 to the pressure frame assembly 11 is not limited here.

[0042] Specifically, the baffle 13 completely covers the frame assembly 11, the connecting assembly 12, and the frame 20. In this way, the outer frameless part 20 of the baffle 13 and the other components of the shading device 10 are exposed, which can form complete shading, thereby maximizing the integration of the photovoltaic array 100 with the installation environment and making the photovoltaic array 100 more aesthetically pleasing overall.

[0043] In other embodiments, the baffle 13 may partially obscure the frame assembly 11, the connecting assembly 12, and the frame 20. In other words, one or more of the frame assembly 11, the connecting assembly 12, and the frame 20 may be partially obscured by the baffle 13, while the remaining portions may not be obscured by the baffle 13.

[0044] For example, the baffle 13 covers part of the frame assembly 11, the entirety of the connecting component 12, and the entirety of the border 20; or, the baffle 13 covers part of the frame assembly 11, part of the connecting component 12, and the entirety of the border 20; or, the baffle 13 covers part of the frame assembly 11, part of the connecting component 12, and part of the border 20. The specific manner in which the baffle 13 covers the frame assembly 11, the connecting component 12, and the border 20 is not limited here.

[0045] Specifically, the baffle 13 is made of at least one of aluminum alloy, stainless steel, and carbon steel. The baffle 13 can be formed by bending aluminum alloy sheet, stainless steel sheet, or carbon steel sheet. In this way, the baffle 13 has high strength, low cost, and better blocking effect.

[0046] Example 2

[0047] Please see Figure 1 and Figure 3In some alternative embodiments, the frame pressing assembly 11 includes a pressing block 111, a connecting plate 112, and a first fastener 113. The pressing block 111 is used to press down the top of the frame 20, the connecting plate 112 is used to abut against the bottom of the frame 20 and cooperate with the pressing block 111, and the first fastener 113 is used to fasten the pressing block 111 and the connecting plate 112, fixing the frame 20 between the pressing block 111 and the connecting plate 112.

[0048] In this way, the pressure block 111 and the connecting plate 112 cooperate and are fastened by the first fastener 113, fixing the frame 20 between the pressure block 111 and the connecting plate 112. This eliminates the need to drill holes in the frame 20 for the fixed connection between the frame assembly 11 and the frame 20, which helps ensure the integrity of the frame 20 and avoids damage due to obstruction. Furthermore, this allows for flexible adjustment of the fixed positions of the pressure block 111 and the connecting plate 112 in the extending direction of the frame 20.

[0049] Specifically, the pressure block 111 directly abuts against the top of the frame 20. This results in high installation efficiency.

[0050] In other embodiments, an adhesive, solder or other connector may be provided between the pressure block 111 and the top of the frame 20.

[0051] Specifically, the surface of the pressure block 111 facing the top of the frame 20 is flat, and the top surface of the frame 20 is also flat. This results in a larger contact area between the pressure block 111 and the top of the frame 20, and a better fastening effect between the frame 20 and the pressure block 111.

[0052] In other embodiments, the surface of the pressure block 111 facing the top of the frame 20 can form a mating concave-convex structure with the top surface of the frame 20. This can further increase the contact area and friction, thereby improving the fastening effect between the frame 20 and the pressure block 111.

[0053] Specifically, the bottom surface of the connecting plate 112 facing the frame 20 is flat, and the bottom surface of the frame 20 is also flat. This results in a larger contact area between the connecting plate 112 and the bottom of the frame 20, and a better fastening effect between the frame 20 and the connecting plate 112.

[0054] In other embodiments, the surface of the connecting plate 112 facing the bottom of the frame 20 and the surface of the bottom of the frame 20 can form a mating concave-convex structure. This can further increase the contact area and increase friction, thereby improving the fastening effect between the frame 20 and the connecting plate 112.

[0055] Specifically, the first fastener 113 can fasten the pressure block 111 and the connecting plate 112 by welding, bonding, snapping, riveting, threading, or other means, thereby fixing the frame 20 between the pressure block 111 and the connecting plate 112. The specific method by which the first fastener 113 fastens the pressure block 111 and the connecting plate 112 is not limited here.

[0056] In other embodiments, the pressure block 111 may be omitted, and the pressure frame assembly 11 may include a connecting plate 112 and a first fastener 113, the first fastener 113 being used to fix the connecting plate 112 to the frame 20. In other embodiments, the connecting plate 112 may also be omitted, and the pressure frame assembly 11 may include the pressure block 111 and the first fastener 113, the first fastener 113 being used to fix the pressure block 111 to the frame 20, and the connecting assembly 12 connecting the baffle 13 to the pressure block 111. The specific form of the pressure frame assembly 11 is not limited here.

[0057] Example 3

[0058] Please see Figure 1 , Figure 3 and Figure 4 In some alternative embodiments, the pressure block 111 has a first connecting hole 1110, the connecting plate 112 has a second connecting hole 1120, and the first fastener 113 is used to pass through the first connecting hole 1110 and the second connecting hole 1120 to fasten the pressure block 111 and the connecting plate 112.

[0059] In this way, the fasteners and connecting holes are used to fasten the pressure block 111 and the connecting plate 112, which is simple and quick and helps to improve production efficiency and assembly efficiency.

[0060] Specifically, the first connecting hole 1110 and the second connecting hole 1120 have the same shape. This facilitates the passage of the first fastener 113 through the first connecting hole 1110 and the second connecting hole 1120. Furthermore, both the first connecting hole 1110 and the second connecting hole 1120 are circular in shape. This facilitates manufacturing. In other embodiments, the shapes of the first connecting hole 1110 and the second connecting hole 1120 can be different, and can be rectangular, triangular, elliptical, or other shapes.

[0061] Specifically, in the insertion direction of the first fastener 113, the center points of the first connecting hole 1110 and the second connecting hole 1120 coincide. This ensures that the positions of the first connecting hole 1110 and the second connecting hole 1120 correspond.

[0062] Specifically, the first fastener 113 includes a bolt and a nut that cooperate with each other. After the bolt passes through the first connecting hole 1110 and the second connecting hole 1120, it cooperates with the nut to fix the relative position of the pressure block 111 and the connecting plate 112, so that the pressure block 111 and the connecting plate 112 clamp the frame 20. In this way, the relative position of the pressure block 111 and the connecting plate 112 can be fixed conveniently and efficiently. It can be understood that the relative position of the pressure block 111 and the connecting plate 112 can be adjusted by adjusting the position of the nut on the bolt, thereby adjusting the degree of clamping of the pressure block 111 and the connecting plate 112 on the frame 20.

[0063] In other embodiments, the first fastener 113 may include a cable tie, one end of which passes through the first connecting hole 1110 and the second connecting hole 1120 and is inserted into the buckle at the other end of the cable tie, thereby fixing the relative position of the pressure block 111 and the connecting plate 112, so that the pressure block 111 and the connecting plate 112 clamp the frame 20. The first fastener 113 may also take other forms, which are not limited here.

[0064] Specifically, the pressure block 111 may include a hole, a first pressing part, and a second pressing part. The hole has a first connecting hole 1110. The first pressing part and the second pressing part extend outward from the hole. The first pressing part presses against the top of the frame 20, and the second pressing part presses against the side of the frame 20. In this way, the top and side of the frame 20 can be pressed simultaneously, thereby achieving a more stable fixed connection with the frame 20.

[0065] Specifically, the hole and the connecting plate 112 are parallel to each other and perpendicular to the extension direction of the first fastener 113. In this way, the pressure block 111 and the connecting plate 112 cooperate with each other, and after the first fastener 113 tightens the pressure block 111 and the connecting plate 112, the clamping effect of the frame 20 is better.

[0066] In other embodiments, the second pressing part may be omitted; in other embodiments, the hole and the connecting part may be at an angle. The specific form of the pressure frame assembly 11 is not limited here.

[0067] Specifically, there can be multiple pressure blocks 111, with adjacent pressure blocks 111 spaced apart from each other. In this way, multiple pressure blocks 111 can be fixed to the frame 20 and cooperate with the support beam 121, making the connection between the baffle 13 and the frame 20 more stable.

[0068] Please see Figure 4 The diameter of the second connecting hole 1120 is 5mm-12mm. For example, it is 5mm, 7mm, 9mm, 10mm, or 12mm. Preferably, the diameter of the second connecting hole 1120 is 9mm. This ensures that the diameter of the second connecting hole 1120 is within a suitable range, allowing for a better fit with the first fastener 113.

[0069] Please see Figure 4 The length of the connecting plate 112 is 90mm-95mm. For example, 90mm, 92mm, 93.8mm, 94mm, or 95mm. Preferably, the length of the connecting plate 112 is 93.8mm. The width of the connecting plate 112 is 35mm-45mm. For example, 35mm, 38mm, 40mm, 42mm, or 45mm. Preferably, the width of the connecting plate 112 is 40mm. The thickness of the connecting plate 112 is 1mm-3mm. For example, 1mm, 2mm, or 3mm. Preferably, the thickness of the connecting plate 112 is 2mm. This ensures that the dimensions of the connecting plate 112 are within a suitable range, facilitating its fit with the connecting assembly 12 and the frame 20.

[0070] Example 4

[0071] Please see Figure 5 In some alternative embodiments, the connecting assembly 12 includes a support beam 121 and a second fastener 122, the frame pressing assembly 11 includes a connecting plate 112, the support beam 121 is disposed on the side of the baffle 13 facing the frame pressing assembly 11, and the second fastener 122 is used to fasten the support beam 121 and the connecting plate 112, so that the baffle 13 covers the frame pressing assembly 11, the connecting assembly 12 and the frame 20.

[0072] Thus, the support beam 121 provided on the baffle 13 is fastened to the connecting plate 112 of the pressure frame assembly 11 by the second fastener 122, so that the baffle 13 is connected to the pressure frame assembly 11 which is fixedly connected to the frame 20, thereby making the baffle 13 stably shield the pressure frame assembly 11, the connecting assembly 12 and the frame 20.

[0073] Specifically, the extension direction of the support beam 121 is parallel to the length direction of the baffle 13. In this way, the support beam 121 can better support the weight of the baffle 13, allowing the baffle 13 to provide more stable blocking. It can be understood that the length direction of the baffle 13 is the direction of its extension, that is... Figure 2 The length or width of the middle border 20.

[0074] Specifically, the support beam 121 may be provided on the side of the baffle 13 facing the pressure frame assembly 11 by welding, bonding, snap-fitting, riveting, threaded connection or other means. The specific manner in which the support beam 121 is provided on the baffle 13 is not limited here.

[0075] Specifically, the second fastener 122 secures the support beam 121 to the side of the connecting plate 112 facing away from the frame 20, that is, the lower side of the connecting plate 112. In other embodiments, the second fastener 122 can secure the support beam 121 to the side of the connecting plate 112 facing the frame 20, that is, the upper side of the connecting plate 112. The specific positional relationship between the support beam 121 and the connecting plate 112 is not limited here.

[0076] Specifically, the surface of the support beam 121 facing the bottom of the connecting plate 112 is flat, and the bottom surface of the connecting plate 112 is also flat. This results in a larger contact area between the support beam 121 and the bottom surface of the connecting plate 112, and a better fastening effect between the support beam 121 and the connecting plate 112.

[0077] In other embodiments, the surface of the support beam 121 facing the bottom surface of the connecting plate 112 can form a mating concave-convex structure with the bottom surface of the connecting plate 112. This can further increase the contact area and friction, thereby improving the fastening effect between the support beam 121 and the connecting plate 112.

[0078] Specifically, the second fastener 122 can secure the support beam 121 and the connecting plate 112 by welding, bonding, snapping, riveting, threading, or other means, so that the baffle 13 covers the pressure frame assembly 11, the connecting assembly 12, and the frame 20. The specific method by which the second fastener 122 secures the support beam 121 and the connecting plate 112 is not limited here.

[0079] Example 5

[0080] Please see Figure 1 , Figure 6 and Figure 7 In some alternative embodiments, the connecting component 12 includes a slot 123, the bottom wall of which is fixed to the side of the baffle 13 facing the pressure frame component 11, and the support beam 121 is inserted into the slot 123 to connect with the baffle 13.

[0081] In this way, the support beam 121 is fixed to the side of the baffle 13 facing the pressure frame assembly 11 through the slot 123, which is simple and convenient and helps to improve assembly efficiency.

[0082] Specifically, the bottom wall of the slot 123 is welded to the side of the baffle 13 facing the pressure frame assembly 11. In other embodiments, the slot 123 may be provided on the side of the baffle 13 facing the pressure frame assembly 11 by welding, bonding, snapping, riveting, threading or other means.

[0083] Please see Figure 7 and Figure 8 Specifically, there are multiple slots 123, with adjacent slots 123 spaced apart. In this way, the support beam 121 is fixed by multiple slots 123, making the connection between the support beam 121 and the baffle 13 more stable.

[0084] Furthermore, multiple slots 123 are arranged sequentially along the length of the baffle 13. This allows the support beam 121 to be positioned along the length of the baffle 13, better supporting the weight of the baffle 13 and thus enabling the baffle 13 to provide more stable blocking. It can be understood that the length direction of the baffle 13 is the direction in which the baffle 13 extends, that is... Figure 2 The length or width of the middle border 20.

[0085] Furthermore, multiple slots 123 are arranged at equal intervals. In this way, each slot 123 provides roughly the same support for the support beam 121, making the connection between the support beam 121 and the baffle 13 more stable.

[0086] Example 6

[0087] Please see Figure 1 and Figure 6 In some alternative embodiments, the slot 123 has an open end on the side facing the pressure frame assembly 11, and the support beam 121 is inserted into the slot 123 from the open end. The open end has a folded edge 1231 that bends inward toward the inside of the slot 123.

[0088] Thus, after the support beam 121 is inserted into the slot 123, the support beam 121 is difficult to slip out of the slot 123 due to the obstruction of the folded edge 1231. This hook-like snap-fit ​​design makes the installation of the support beam 121 in the slot 123 more stable, convenient and reliable.

[0089] Specifically, there are two folded edges 1231, which are formed on the two side walls of the slot 123 respectively, and the two folded edges 1231 are symmetrical. This facilitates manufacturing and installation.

[0090] Please see Figure 6 The width L1 of the card slot 123 is 30mm-35mm. For example, it is 30mm, 31.6mm, 34mm, or 35mm. Preferably, the width L1 of the card slot 123 is 31.6mm. The length L2 of the card slot 123 is 38mm-42mm. For example, it is 38mm, 39mm, 40.3mm, or 42mm. Preferably, the length L2 of the card slot 123 is 40.3mm. The length L3 of the folded edge 1231 is 5mm-10mm. For example, it is 5mm, 7mm, 8.2mm, or 10mm. Preferably, the length L3 of the folded edge 1231 is 8.2mm. The bending angle α of the folded edge 1231 is 20°-25°. For example, it is 20°, 21°, 23°, or 25°. Preferably, the bending angle α of the folded edge 1231 is 21°. This ensures that the size of the slot 123 is within a suitable range, allowing the slot 123 to better fit with the support beam 121 and the connecting plate 112.

[0091] Example 7

[0092] Please see Figure 1 , Figure 4 and Figure 8 In some alternative embodiments, the connecting plate 112 is formed with a third connecting hole 1121, the slot 123 is formed with a fourth connecting hole, the support beam 121 is formed with a fifth connecting hole 1210, and the second fastener 122 is used to pass through the third connecting hole 1121, the fourth connecting hole and the fifth connecting hole 1210 to fasten the connecting plate 112, the slot 123 and the support beam 121.

[0093] In this way, the fastening of the connecting plate 112, the slot 123 and the support beam 121 is achieved through fasteners and connecting holes, which is simple and quick and helps to improve production efficiency and assembly efficiency.

[0094] Specifically, the third connecting hole 1121, the fourth connecting hole, and the fifth connecting hole 1210 have the same shape. This facilitates the passage of the second fastener 122 through the third connecting hole 1121, the fourth connecting hole, and the fifth connecting hole 1210. Furthermore, the third connecting hole 1121, the fourth connecting hole, and the fifth connecting hole 1210 are all circular in shape. This facilitates manufacturing. In other embodiments, the shapes of the third connecting hole 1121, the fourth connecting hole, and the fifth connecting hole 1210 can be different, and can be rectangular, triangular, elliptical, or other shapes.

[0095] Specifically, in the insertion direction of the second fastener 122, the center points of the third connecting hole 1121, the fourth connecting hole, and the fifth connecting hole 1210 coincide. This ensures that the positions of the third connecting hole 1121, the fourth connecting hole, and the fifth connecting hole 1210 are corresponding.

[0096] Specifically, the second fastener 122 includes a bolt and a nut that cooperate with each other. After the bolt passes through the third connecting hole 1121, the fourth connecting hole, and the fifth connecting hole 1210, it cooperates with the nut to fix the relative positions of the connecting plate 112, the slot 123, and the support beam 121. In this way, the relative positions of the connecting plate 112, the slot 123, and the support beam 121 can be fixed conveniently and efficiently. It can be understood that the relative positions of the connecting plate 112, the slot 123, and the support beam 121 can be adjusted by adjusting the position of the nut on the bolt.

[0097] In other embodiments, the second fastener 122 may include a cable tie, one end of which passes through the third connecting hole 1121, the fourth connecting hole, and the fifth connecting hole 1210, and is then inserted into the buckle at the other end of the cable tie, thereby fixing the relative positions of the connecting plate 112, the slot 123, and the support beam 121. The second fastener 122 may also take other forms, which are not limited here.

[0098] Please see Figure 4The diameter of the third connecting hole 1121 is 5mm-12mm. For example, it is 5mm, 7mm, 9mm, 10mm, or 12mm. Preferably, the diameter of the third connecting hole 1121 is 9mm. This ensures that the diameter of the third connecting hole 1121 is within a suitable range, allowing for better fit with the second fastener 122.

[0099] Please see Figure 4 The distance d1 between the third connecting hole 1121 and the second connecting hole 1120 is 35mm-40mm. For example, it is 35mm, 37mm, 38.2mm, 39mm, or 40mm. Preferably, the distance d1 between the third connecting hole 1121 and the second connecting hole 1120 is 38.2mm. This ensures that the distance d1 between the third connecting hole 1121 and the second connecting hole 1120 is within a suitable range, facilitating cooperation with the first fastener 113 and the second fastener 122. It can be understood that the position of the baffle 13 and the frame 20 can be adjusted by adjusting the distance d1 between the third connecting hole 1121 and the second connecting hole 1120, which is convenient and flexible.

[0100] Please see Figure 8 The diameter of the fifth connecting hole 1210 is 5mm-12mm. For example, it is 5mm, 7mm, 9mm, 10mm, or 12mm. Preferably, the diameter of the fifth connecting hole 1210 is 9mm. This ensures that the diameter of the fifth connecting hole 1210 is within a suitable range, allowing for a better fit with the second fastener 122.

[0101] Please see Figure 8 There are multiple fifth connecting holes 1210, arranged sequentially along the length of the support beam 121. In this way, multiple positions of the support beam 121 can be fixed to the slot 123 and the connecting plate 112, thereby making the connection between the support beam 121, the slot 123 and the connecting plate 112 more stable, which is conducive to the stable blocking of the baffle 13.

[0102] Please see Figure 8 The distance d2 between two adjacent fifth connecting holes 1210 is 700mm-900mm. For example, it is 700mm, 750mm, 800mm, 880mm, or 900mm. Preferably, the distance d2 between two adjacent fifth connecting holes 1210 is 800mm. This ensures that the distance d2 between two adjacent fifth connecting holes 1210 is within a suitable range, preventing waste and installation trouble caused by a distance d2 that is too small, and also preventing instability in the middle of the support beam 121 caused by a distance d2 that is too large.

[0104] Please see Figure 7 , Figure 9 and Figure 10In some optional embodiments, the photovoltaic array 100 is applied to the photovoltaic system 1000, which includes a photovoltaic bracket 200, a cable 300, and a grounding wire 400.

[0105] Thus, the baffle 13 can not only cover the frame 20 of the photovoltaic array 100, the frame pressing component 11 and the connecting component 12 of the edge covering device 10, but also cover at least one of the photovoltaic bracket 200, cable 300 and grounding wire 400, thereby further reducing the exposed components of the photovoltaic system 1000 and making the overall photovoltaic system 1000 more aesthetically pleasing.

[0106] Specifically, in Figure 10 In the example, the third connection is used to shield the photovoltaic bracket 200, cable 300, and grounding wire 400. In this way, the baffle 13 can shield the internal structure of the photovoltaic system 1000 to the greatest extent.

[0107] In other embodiments, the third shielding part 133 may shield one of the photovoltaic bracket 200, the cable 300 and the grounding wire 400; or it may shield two of the photovoltaic bracket 200, the cable 300 and the grounding wire 400.

[0108] Please see Figure 7 The length D1 of the first blocking portion 131 is 8mm-12mm. For example, it is 8mm, 9.8mm, 10mm, or 12mm. Preferably, the length D1 of the first blocking portion 131 is 9.8mm. The angle β1 formed by the first blocking portion 131 and the horizontal plane is 10°-15°. For example, it is 10°, 11°, 12°, 14°, or 15°. Preferably, the angle β1 formed by the first blocking portion 131 and the horizontal plane is 12°. Thus, the length D1 and the angle β1 of the first blocking portion 131 are within a suitable range, which can better block the frame 20.

[0109] Please see Figure 7 and Figure 9 The baffle 13 has a first bent portion 1341, a second bent portion 1342, a third bent portion 1343, a fourth bent portion 1344, and a fifth bent portion 1345 that are bent in sequence. The first blocking portion 131 is the first bent portion 1341. The second blocking portion 132 includes all of the second bent portion 1342 and the third bent portion 1343, as well as a portion of the fourth bent portion 1344. The third blocking portion 133 includes the remaining portion of the fourth bent portion 1344 and the fifth bent portion 1345.

[0110] The length D2 of the second bend 1342 is 35-40 mm, preferably 36 mm. The angle β2 between the second bend 1342 and the first bend 1341 is 165°-170°, preferably 168°. The length D3 of the third bend 1343 is 40-45 mm, preferably 43.3 mm. The angle β3 between the third bend 1343 and the second bend 1342 is 133°-138°, preferably 135°. The length D4 of the fourth bend 1344 is 80-85 mm, preferably 83.7 mm. The angle β4 between the fourth bend 1344 and the third bend 1343 is 133°-138°, preferably 135°. The length D5 of the fifth bend 1345 is 40-45 mm, preferably 43.3 mm. The angle β5 between the fifth bend 1345 and the fourth bend 1344 is 148°-153°, preferably 150°. This ensures that the size of the baffle 13 is within a suitable range, enabling better shielding.

[0111] Please see Figure 9 , Figure 9 yes Figure 7 The top view shows that the lengths of the first bend 1341, the second bend 1342, and the third bend 1343 gradually increase.

[0114] The photovoltaic array 100 of this application embodiment includes a shading device 10 of any one of embodiments one to eight, the shading device 10 shading the frame 20 of the photovoltaic array 100.

[0115] The photovoltaic array 100 of this application embodiment uses a baffle 13 to shield the frame 20 of the photovoltaic array 100, the frame pressing component 11 of the shielding device 10 and the connecting component 12, which can reduce the exposure of the photovoltaic array 100 and other components of the shielding device 10, which is conducive to the integration of the photovoltaic array 100 with the installation environment and makes the overall photovoltaic array 100 more aesthetically pleasing.

[0116] In this embodiment, the photovoltaic array 100 includes multiple battery modules. Multiple solar cells in the battery modules can be connected in series to form a battery string, thereby realizing the series current collection and output. For example, the battery cells can be connected in series by setting solder strips (busbars, interconnecting strips), conductive backplates, etc.

[0117] It is understood that in such embodiments, the battery assembly may also include a metal frame, a backsheet, photovoltaic glass, and an encapsulating film. The encapsulating film may be filled between the front and back of the solar cells, the photovoltaic glass, and adjacent cells. As a filler, it may be a transparent colloid with good light transmittance and aging resistance. For example, the encapsulating film may be an EVA film or a POE film, and the specific choice can be made according to the actual situation, without limitation.

[0118] Photovoltaic glass can be applied to the encapsulating film on the front of solar cells. This photovoltaic glass can be ultra-clear glass, possessing high light transmittance, high transparency, and superior physical, mechanical, and optical properties. For example, ultra-clear glass can achieve a light transmittance of over 92%, protecting the solar cells while minimizing impact on their efficiency. Simultaneously, the encapsulating film bonds the photovoltaic glass and the solar cells together, providing sealing, insulation, and waterproofing / moisture protection for the solar cells.

[0119] The backsheet can be attached to the encapsulating film on the back of the solar cell. The backsheet protects and supports the solar cell, providing reliable insulation, water resistance, and aging resistance. Multiple backsheet options are available, typically including tempered glass, acrylic glass, and aluminum alloy TPT composite encapsulating film, etc., depending on the specific circumstances and not limited here. The backsheet, solar cell, encapsulating film, and photovoltaic glass can be mounted on a metal frame. The metal frame serves as the main external support structure for the entire battery module, providing stable support and installation. For example, the battery module can be installed at the desired location using the metal frame.

[0122] The photovoltaic system 1000 of this application embodiment uses a baffle 13 to shield the frame 20 of the photovoltaic array 100, the frame pressing component 11 of the shading device 10, and the connecting component 12. This reduces the exposure of other components of the photovoltaic array 100 and the shading device 10, which is beneficial to the integration of the photovoltaic array 100 with the installation environment and makes the overall photovoltaic array 100 more aesthetically pleasing.

[0123] In this embodiment, the photovoltaic system 1000 can be applied in photovoltaic power plants, such as ground-mounted power plants, rooftop power plants, and floating power plants. It can also be applied to equipment or devices that utilize solar energy for power generation, such as user solar power supplies, solar streetlights, solar cars, and solar buildings.

Taking a photovoltaic power generation system network as an example, the photovoltaic system 1000 may include a photovoltaic array, a combiner box, and an inverter. The photovoltaic array may be an array combination of multiple battery modules; for example, multiple battery modules can form multiple photovoltaic arrays. The photovoltaic array is connected to the combiner box, which can collect the current generated by the photovoltaic array. The collected current flows through the inverter and is converted into AC power required by the mains power grid before being connected to the mains power grid to achieve solar power supply.
