Description

Technical Field

[0001] This disclosure relates to the field of building photovoltaic technology, and more specifically, to a photovoltaic panel module and a photovoltaic power generation system. Background Technology

[0002] Building-integrated photovoltaics (BIPV) technology combines solar power generation technology with building facades, allowing photovoltaic modules to be installed not only on rooftops but also on building facades. This increases the installed capacity and power generation of photovoltaic power generation systems, aligning with the concept of green and sustainable development.

[0003] Currently, most photovoltaic modules used on building facades use standard modules from manufacturers. The slots in the photovoltaic panel frame used to embed the edges of the photovoltaic panel are of a fixed size and can only be used for photovoltaic panels of a certain thickness. For photovoltaic panels of different thicknesses, the frame needs to be customized, resulting in poor versatility. Summary of the Invention

[0004] The purpose of this disclosure is to provide a photovoltaic panel module and a photovoltaic power generation system. The photovoltaic panel module can change the size of the opening of the fixing space used to fix the edge of the photovoltaic panel by simply combining the frame body and different frame fasteners, so as to be suitable for photovoltaic panels of different thicknesses without the need to re-customize the frame body, and has good versatility.

[0005] To achieve the above objectives, a first aspect of this disclosure provides a photovoltaic panel module, comprising:

[0006] The frame body includes a first clamping part and a first connecting part;

[0007] The frame fastener includes a second clamping part, a second connecting part, and an mounting part. The second connecting part cooperates with the first connecting part to form a fixed space for fixing the edge of the photovoltaic panel. The mounting part is used to connect the frame fastener to the exterior of the building.

[0008] Fasteners are used to connect the first connecting part and the second connecting part so that the frame fastener is fixedly connected to the frame body.

[0009] Optionally, the free end of the first clamping part is provided with a first folded edge, the first folded edge extends obliquely toward the second clamping part, the second clamping part is provided with a first slot, the first slot is used to accommodate the first adhesive strip, and when the edge of the photovoltaic panel is located in the fixed space, the first adhesive strip abuts against the surface of the photovoltaic panel.

[0010] Optionally, the first connecting portion is configured as a first groove and / or a first protrusion, and the second connecting portion is configured as a second groove and / or a second protrusion that mates with the first groove and / or the first protrusion.

[0011] Optionally, there are multiple fasteners, and the second connecting part has multiple positioning holes that correspond one-to-one with the fasteners. The fasteners pass through the corresponding positioning holes to fix the first connecting part and the second connecting part together.

[0012] Optionally, the mounting part is provided with a second slot on the side away from the second clamping part. The second slot is used to accommodate the second adhesive strip. The slot opening of the second slot is provided with two flanges. When the mounting part is installed on the exterior of the building, the second adhesive strip and the two flanges abut against the exterior of the building.

[0013] Optionally, the frame body includes multiple individual frame pieces arranged circumferentially along the photovoltaic panel, each individual frame piece extending along the edge of the photovoltaic panel, and adjacent individual frame pieces being fixedly connected by corner brackets.

[0014] Optionally, there may be multiple frame fasteners, which are spaced apart along the extension direction of the single frame.

[0015] Optionally, the single frame and the frame fastener are both integrally constructed.

[0016] A second aspect of this disclosure provides a photovoltaic power generation system, including the aforementioned photovoltaic panel assembly.

[0017] Optionally, there are multiple photovoltaic panel modules, which are laid on the exterior of the building, and the frame bodies of two adjacent photovoltaic panel modules are fixed to the exterior of the building by clamping blocks.

[0018] Through the above technical solution, the photovoltaic panel module includes a frame body, frame fasteners, and fasteners. The frame body includes a first clamping part and a first connecting part. The frame fastener includes a second clamping part, a second connecting part, and an mounting part. The mounting part is used to connect the frame fastener to the building facade. The fasteners are used to connect the first connecting part and the second connecting part so that the frame fastener is fixedly connected to the frame body. The second connecting part and the first connecting part cooperate to form a fixed space for fixing the edge of the photovoltaic panel. The fixed space is equivalent to a receiving groove for embedding the photovoltaic panel. By simply using frame fasteners and frame bodies of different specifications, the size of the opening of the fixed space can be changed. Therefore, there is no need to replace the frame body, and the fixed space can be adapted to photovoltaic panels of different thicknesses, resulting in better versatility.

Detailed Implementation

[0028] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0029] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" refer to the inner and outer contours of a component or structure itself. Terms such as "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Furthermore, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same element.

[0030] Through research, the inventors discovered that currently, the installation of photovoltaic modules on the exterior of buildings typically involves inserting the photovoltaic panels into the receiving grooves of the frame, and then fixing the frame to the keel of the building exterior. However, the size of the receiving groove of the frame is generally fixed and can only accommodate photovoltaic panels of a certain thickness. For photovoltaic panels of different thicknesses, it is necessary to make specific customizations, resulting in poor versatility of photovoltaic panel frames.

[0031] Regarding the above issues, such as Figures 1 to 5 As shown, the first aspect of this disclosure proposes a photovoltaic panel assembly, including a frame body 200, a frame fastener 20, and a fastener 30. The frame body 200 includes a first clamping part 16 and a first connecting part 11. The frame fastener 20 includes a second clamping part 27, a second connecting part 21, and a mounting part 22. The mounting part 22 is used to connect the frame fastener 20 to the exterior facade of a building. The fastener 30 is used to connect the first connecting part 11 and the second connecting part 21 so that the frame fastener 20 is fixedly connected to the frame body 200. The second connecting part 21 and the first connecting part 11 cooperate to form a fixed space for fixing the edge of the photovoltaic panel 60 by the first clamping part 16 and the second clamping part 27. The fixed space is equivalent to a receiving groove for embedding the photovoltaic panel 60. By simply combining frame fasteners 20 and frame body 200 of different specifications, the size of the opening of the fixed space can be changed. Therefore, without replacing the frame body 200, the fixed space can be adapted to photovoltaic panels 60 of different thicknesses, resulting in better versatility.

[0032] like Figures 1 to 4 As shown, in some embodiments, the free end of the first clamping part 16 is provided with a first folded edge 17, the first folded edge 17 extends obliquely toward the second clamping part 27, the second clamping part 27 is provided with a first slot 28, the first slot 28 is used to accommodate the first adhesive strip 50, when the edge of the photovoltaic panel 60 is located in the fixed space, the first adhesive strip 50 abuts against the surface of the photovoltaic panel 60.

[0033] In the above embodiment, the free end of the first clamping part 16 is provided with a first folded edge 17 that is inclined toward the second clamping part 27, which is equivalent to adding a reinforcing rib to the first clamping part 16, thereby increasing the strength of the first clamping part 16. A first adhesive strip 50 can be provided in the first slot 28 of the second clamping part 27. When the edge of the photovoltaic panel 60 is located in the fixed space, the first adhesive strip 50 abuts against the surface of the photovoltaic panel 60, so that there is soft contact between the second clamping part 27 and the first adhesive strip 50, preventing the second clamping part 27 from bumping or scratching the surface of the photovoltaic panel 60 and causing damage to the photovoltaic panel 60.

[0034] In some embodiments, the first clamping part 16 may be configured as a strip plate extending along the photovoltaic panel 60. The free end of the strip plate is provided with a first folded edge 17 extending obliquely toward the second clamping part 27. The provision of the first folded edge 17 is equivalent to adding a reinforcing rib to the strip plate, which can increase the strength of the strip plate and make the strip plate less prone to deformation.

[0035] like Figure 1 and Figure 4 As shown, in some embodiments, the fastener 30 may be configured as a screw that passes through the first connecting portion 11 and the second connecting portion 21 to fix the first connecting portion 11 and the second connecting portion 21 together, so that the frame fastener 20 is fixedly connected to the frame body 200.

[0036] In some embodiments, the first connecting part 11 is configured as a first groove 112 and / or a first protrusion 111, and the second connecting part 21 is configured as a second groove 212 and / or a second protrusion 213 that cooperates with the first groove 112 and / or the first protrusion 111. By cooperating with the first connecting part 11 and the second connecting part 21, the frame fastener 20 and the frame body 200 can be limited, restricting the movement of the frame body 200 and the frame fastener 20 in the thickness direction of the first protrusion 111. Then, the first connecting part 11 and the second connecting part 21 are fixed by the fastener 30, which can make the connection between the first connecting part 11 and the second connecting part 21 more secure.

[0037] In the above embodiments, the first connecting part 11 may be configured as a first groove 112, and the second connecting part 21 may be configured as a second protrusion 213. The second protrusion 213 is inserted into the first groove 112, and the fastener 30 passes through the first groove 112 and the second protrusion 213 to fix the second protrusion 213 in the first groove 112; or the first connecting part 11 may be configured as a first protrusion 111, and the second connecting part 21 may be configured as a second groove 212. The first protrusion 111 is inserted into the second groove 212, and the fastener 30 passes through the first protrusion 111 and the second groove 212 to fix the first protrusion 111 in the second groove 212.

[0038] Or such as Figures 1 to 4As shown, the first connecting portion 11 is constructed with a first groove 112 and a first protrusion 111. The first protrusion 111 may be plate-shaped. The first groove 112 is formed by the first protrusion 111, a first vertical plate 13, and a first horizontal plate 12. The second connecting portion 21 is constructed with a second groove 212 and a second protrusion 213. The second protrusion 213 may be plate-shaped. The second protrusion 213 may be constructed as a sidewall of the second groove 212. The other sidewall of the second groove 212 may be a third protrusion 211. The second connecting portion 21 may also be constructed with a second groove 212 and a second protrusion 213. The third protrusion 211, the second protrusion 213, the third protrusion 211, and the fourth vertical plate 26 form a second groove 212. The first protrusion 111 can be inserted into the second groove 212. At this time, the second protrusion 213 is inserted into the second groove 212. In the direction from the second clamping part 27 to the mounting part 22, the relative movement between the frame body 200 and the frame fastener 20 can be restricted. Then, screws are used to pass through the first protrusion 111, the third protrusion 211, and the second protrusion 213 in sequence to fix the frame fastener 20 onto the frame body 200.

[0039] In some embodiments, there are multiple fasteners 30, and the second connecting part 21 has multiple positioning holes that correspond one-to-one with the fasteners 30. The fasteners 30 pass through the corresponding positioning holes to fix the first connecting part 11 and the second connecting part 21 together. The arrangement of multiple fasteners 30 can make the connection between the first connecting part 11 and the second connecting part 21 more secure.

[0040] In the above embodiment, the fastener 30 is constructed as a screw. Multiple screws can directly fix the first protrusion 111, the third protrusion 211 and the second protrusion 213 together. Alternatively, positioning holes can be opened on the third protrusion 211. There are multiple positioning holes. Multiple screws pass through the positioning holes to fix the first protrusion 111, the third protrusion 211 and the second protrusion 213. The positioning holes facilitate the positioning of the screw installation position.

[0041] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, a second slot 23 is provided on the side of the mounting part 22 away from the second clamping part 27. The second slot 23 is used to accommodate the second adhesive strip 40. The slot opening of the second slot 23 is provided with two flanges 222. When the mounting part 22 is installed on the exterior of the building, the second adhesive strip 40 and the two flanges 222 abut against the exterior of the building.

[0042] In the above-described embodiments, a keel 70 can generally be installed on the exterior facade of the building, and the mounting part 22 is installed on the keel 70. The second adhesive strip 40 abuts against the keel 70 on the exterior facade of the building, which can make partial soft contact between the frame fastener 20 and the keel 70 on the exterior facade of the building. This can reduce the area of ​​rigid contact between the mounting part 22 of the frame fastener 20 and the keel 70 on the exterior facade of the building. When the frame fastener 20 shakes, it can reduce the noise generated by the rigid contact between the frame fastener 20 and the keel 70 on the exterior facade of the building.

[0043] In addition, the flange 222 of the frame fastener 20 abuts against the keel 70 of the building facade, which can prevent the clamping surface of the second clamping part 27 used to clamp the photovoltaic panel 60 from tilting and failing to clamp the photovoltaic panel 60 better.

[0044] like Figure 5 As shown, in some embodiments, the frame body 200 includes a plurality of individual frame 10 arranged circumferentially along the photovoltaic panel 60, each individual frame 10 extending along the edge of the photovoltaic panel 60, and adjacent individual frame 10 are fixedly connected by corner brackets 100.

[0045] In the above embodiment, the contacting end faces between adjacent single frame frames 10 can be cut so that each end face forms a preset angle with the extension direction of the single frame frame 10, so as to facilitate the docking of the single frame frames 10 of the bell. For example, the preset angle can be 45°.

[0046] Furthermore, the first connecting portion 11, the first clamping portion 16, and the first folded edge 17 provided at the free end of the first clamping portion 16 of each individual frame 10 are all the first connecting portion 11, the first clamping portion 16, and the first folded edge 17 provided at the free end of the first clamping portion 16 of the frame body 200.

[0047] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, a first channel 14 is also provided on the single frame 10. The first channel 14 is formed by the first horizontal plate 12, the first vertical plate 13, the second vertical plate 15 and the portion of the first clamping part 16 located between the first vertical plate 13 and the second vertical plate 15 on the single frame 10. Angle brackets 100 can be set in the first channel 14 of adjacent single frames 10 to fix adjacent single frames 10 using angle brackets 100 to form a frame body 200. The photovoltaic panel 60 is accommodated in the fixed space formed by the first clamping part 16 and the second clamping part 27 of the frame body 200. A rubber gasket can be provided between the photovoltaic panel 60 and the inner wall of the fixed space to prevent the photovoltaic panel 60 from directly contacting the inner wall of the fixed space and causing damage such as scratches to the photovoltaic panel 60.

[0048] In some embodiments, there are multiple frame fasteners 20, which are spaced apart along the extension direction of the individual frame 10. The number and spacing of the frame fasteners 20 can be set according to the actual situation to more stably fix the photovoltaic panel 60.

[0049] In some embodiments, the single frame 10 and the frame fastener 20 are both integrally constructed.

[0050] A second aspect of this disclosure provides a photovoltaic power generation system, including the aforementioned photovoltaic panel assembly.

[0051] In some implementations, there are multiple photovoltaic panel modules, which are laid on the exterior of the building. The frame bodies 200 of two adjacent photovoltaic panel modules are fixed to the exterior of the building by pressure blocks 90.

[0052] In the above embodiment, the building facade is provided with a keel 70 for fixing the frame body 200. The frame body 200 is fixed to the keel 70 of the building facade by a frame fastener 20 provided on the frame body 200. One end of the mounting part 22 is provided with a third vertical plate 24. One end of the third vertical plate 24 is connected to the mounting part 22, and the other end of the third vertical plate 24 is connected to a second horizontal plate 25. The end of the second horizontal plate 25 away from the third vertical plate 24 is connected to a fourth vertical plate 26. The end of the fourth vertical plate 26 away from the second horizontal plate 25 is connected to a second clamping part 27. The second connecting part 21 and the second clamping part 27 are respectively provided on opposite sides of the fourth vertical plate 26. In addition, the second clamping part 27 is also provided with a first protruding plate 271. When the frame fastener 20 is fixed on the frame body 200, the first protruding plate 271 abuts against the frame body 200.

[0053] In some embodiments, the mounting part 22, the third vertical plate 24, and the second horizontal plate 25 enclose a third groove 29. Frame fasteners 20 mounted on the same keel 70 on the frame bodies 200 of adjacent photovoltaic panels can be correspondingly provided. A pressure block 90 is disposed in the third groove 29 of two corresponding frame fasteners 20. The pressure block 90 presses against the mounting part 22, fixing the frame fasteners 20 to the keel 70 of the building facade. A protrusion is formed on the edge of the surface of the pressure block 90 that contacts the mounting part 22. A protrusion 221 can be formed on the mounting part 22. When the pressure block 90 presses against the mounting part 22, the protrusion 221 abuts against the pressure block 90, and the protrusion on the edge of the pressure block 90 abuts against the mounting part 22. The two cooperate to maintain the stability of the pressure block 90 when pressed against the mounting part 22. Furthermore, a through hole can be provided on the pressure block 90, and the pressure block 90 is fixed to the keel 70 by a connector 80.

[0054] Specifically, the connector 80 can be constructed as a bolt and a nut. A snap-fit ​​groove is opened on the keel 70. The bolt passes through the through hole provided on the pressure block 90 and extends into the snap-fit ​​groove of the keel 70. A nut is provided in the snap-fit ​​groove. The bolt and the nut cooperate to fix the pressure block 90 to the keel 70, that is, fix the frame fastener 20 to the keel 70. In addition, the frame body 200 is fixed to the keel 70 by multiple frame fasteners 20. The photovoltaic panel 60 is installed on the keel 70 by the frame body 200 and the frame fasteners 20.

[0055] In some implementations, the photovoltaic power generation system also includes a controller, an inverter, a battery, and other accessories, and the photovoltaic panel 60 of the photovoltaic panel assembly can convert solar energy into electrical energy and store it in the battery.

[0056] In addition, photovoltaic power generation systems can also be connected to the public power grid, which will not be elaborated here.
