[0032] With the increasing development of renewable energy technologies, photovoltaic (PV) technology is being applied more and more widely in various fields. In the field of solar PV applications, PV devices, such as PV shading structures, are widely used because they can generate electricity while blocking sunlight. In related technologies, PV devices include PV modules and supporting components. The PV modules are mounted on the supporting components and transmit power and communication with energy storage or inverters via wiring harnesses. However, if the number of PV components in a PV module is large, the wiring may become complex. Therefore, how to provide a PV device with a simple wiring design has become a technical problem that urgently needs to be solved by those skilled in the art. To solve the above problem, please refer to [link to relevant documentation]. Figure 1 or Figure 4 This application provides a photovoltaic device 100.

[0033] Please see Figure 1 or Figure 4The photovoltaic device 100 of this application includes a support component 10, a photovoltaic module 20, and an electrical component 30. The support component 10 includes multiple brackets 11, which are made of conductive material. The photovoltaic module 20 is mounted on the support component 10. The electrical component 30 is mounted on the support component 10 and configured to be electrically connected to the photovoltaic module 20 through the brackets 11. It should be noted that in some embodiments, the photovoltaic device 100 includes, but is not limited to, photovoltaic sunshades, photovoltaic carports, ground-mounted power stations, and floating photovoltaic systems. This application describes the photovoltaic device 100 including a photovoltaic sunshade as an example.

[0034] As is understood, a photovoltaic (PV) awning is a photovoltaic product that can generate electricity using solar energy while also providing shade, insulation, and rain protection. PV awnings can be applied to outdoor public areas, the perimeter of large commercial facilities, or the courtyards of private residences. For example, a PV awning can be installed on a rooftop for use as a shading facility; or, a PV awning can be installed in a courtyard for use as a shading canopy.

[0035] The support component 10 is a structure in the photovoltaic device 100 that provides installation and support for the photovoltaic module 20. In some embodiments of this application, the support component 10 includes multiple brackets 11, which are made of conductive materials, including but not limited to aluminum alloy, copper, silver, carbon fiber, and composite conductive plastics. For example, the brackets 11 can be made of aluminum alloy, which not only enables the brackets 11 to have conductive function, but also improves the structural strength of the support component 10, enhances the photovoltaic device 100's ability to resist external environmental factors (such as wind, rain, snow, etc.), and ensures the stability and reliability of the photovoltaic device 100's operation.

[0036] In some embodiments, all of the multiple brackets 11 are made of conductive material, that is, each bracket 11 can provide electrical connection between the photovoltaic module 20 and the electrical component 30, thus facilitating the expansion of the photovoltaic module 20. In other embodiments, some of the multiple brackets 11 are made of conductive material, for example, the bracket 11 connecting the photovoltaic module 20 and the electrical component 30 is made of conductive material.

[0037] A photovoltaic module 20 is a structure in a photovoltaic device 100 capable of converting solar energy into electrical energy. The photovoltaic module 20 can be mounted on top of the support assembly 10 or at a specific mounting location on the support assembly 10, and is electrically connected to the bracket 11 of the support assembly 10. In some embodiments of this application, the photovoltaic module 20 includes a photovoltaic panel for converting solar energy into electrical energy. The photovoltaic panel can be different types of solar energy conversion devices such as monocrystalline silicon, polycrystalline silicon, or thin-film solar cells. Users can select photovoltaic panels of different efficiencies and sizes according to their usage requirements and frame structure.

[0038] Electrical component 30 is a structure in photovoltaic device 100 that can be electrically connected and cooperate with photovoltaic module 20. In some embodiments of this application, electrical component 30 includes at least one of energy storage component, inverter, and socket. For example, electrical component 30 includes energy storage component, which can be electrically connected to photovoltaic module 20 through bracket 11. Energy storage component can store electrical energy generated by photovoltaic module 20 and can power loads such as household appliances and portable devices. It should be noted that in some embodiments, energy storage component can be lithium-ion battery, lead-acid battery, or other types of rechargeable battery, or it can be a device capable of storing and releasing electrical energy, such as supercapacitor.

[0039] In the photovoltaic device 100 of this application embodiment, the electrical component 30 is configured to be electrically connected to the photovoltaic module 20 via the bracket 11. That is, the photovoltaic device 100 can use the bracket 11 as a conductive line between the electrical component 30 and the photovoltaic module 20 without additional wiring, thereby reducing the use of wire harnesses and making the wiring structure of the photovoltaic device 100 simpler. In turn, it can reduce production costs and simplify the assembly operation of the photovoltaic device 100.

[0040] The photovoltaic device 100 will be further described below with reference to the accompanying drawings.

[0041] Please see Figure 1 or Figure 4 and combined Figure 3 In some embodiments, the support 11 includes a base layer 111 and an encapsulation layer 112. The encapsulation layer 112 is disposed around the outer peripheral wall of the base layer 111, and the conductivity of the encapsulation layer 112 is greater than that of the base layer 111. It should be noted that in some embodiments, the encapsulation layer 112 can be disposed on the outer peripheral wall of the base layer 111 by any one of the processing methods such as electroplating, chemical plating, hot-dip plating, and electroforming.

[0042] It is understood that the base layer 111 is the main structure of the support 11, and the base layer 111 can be made of a conductive material with a certain structural strength. In some embodiments, the base layer 111 can be a solid columnar structure, which can improve the structural strength of the support component 10 and reduce the possibility of deformation and damage to the support component 10. In other embodiments, the base layer 111 can be a hollow columnar structure, which can reduce the weight of the support 11 and help to achieve lightweighting of the support component 10.

[0043] Due to the skin effect of electric current, i.e., under the influence of alternating current or alternating electromagnetic fields, the current distribution inside a conductor is uneven, with the current concentrated on the conductor surface. The closer to the conductor surface, the greater the current density; the closer to the interior of the conductor, the smaller the current density. Therefore, if the conductivity of the conductor surface is low, it may affect the conductivity of the conductor. In some embodiments of this application, the encapsulation layer 112 is disposed around the outer peripheral wall of the base layer 111, and the conductivity of the encapsulation layer 112 is greater than that of the base layer 111. Thus, when the support 11 is used as a conductive line, the current can be mainly conducted through the encapsulation layer 112. Compared to when the conductivity of the encapsulation layer 112 and the base layer 111 are the same, or when the conductivity of the encapsulation layer 112 is less than that of the base layer 111, the current conduction is less hindered, thereby improving the conductivity of the support 11.

[0044] For example, the base layer 111 can be made of aluminum alloy, and the encapsulation layer 112 can be made of copper. Specifically, the encapsulation layer 112 can be electroplated onto the outer peripheral wall of the base layer 111, that is, a copper layer (encapsulation layer 112) is formed on the surface of the aluminum alloy (base layer 111) through electrolysis. In the case that the base layer 111 is made of aluminum alloy, the encapsulation layer 112 can improve the conductivity of the support 11; prevent the formation of an aluminum oxide insulating layer on the surface of the base layer 111, which would hinder current conduction; and fill the micropores or scratches on the surface of the base layer 111, reducing the increase in local resistance caused by poor contact.

[0045] Furthermore, in some embodiments, the support 11 further includes an isolation layer 113, which is disposed between the base layer 111 and the encapsulation layer 112, and serves to block the connection between the base layer 111 and the encapsulation layer 112. It should be noted that in some embodiments, the material of the isolation layer 113 includes at least one of nickel, titanium, and epoxy resin.

[0046] Understandably, when the base layer 111 and the encapsulation layer 112 are in direct contact, the base layer 111 is susceptible to corrosion in humid or electrolyte environments. For example, when aluminum alloy (base layer 111) is in direct contact with copper (encapsulation layer 112), micro-batteries can form in humid or electrolyte environments, with the aluminum alloy acting as the anode and being rapidly corroded. Furthermore, a dense aluminum oxide layer easily forms on the surface of the aluminum alloy, resulting in poor adhesion and easy peeling of the copper layer. Therefore, the isolation layer 113 can, on the one hand, block the direct contact between the base layer 111 and the encapsulation layer 112, reduce the possibility of electrochemical reactions between the base layer 111 and the encapsulation layer 112, ensure that the base layer 111 is protected from corrosion, and extend the service life of the support 11; on the other hand, it can enhance the bonding strength between the base layer 111 and the encapsulation layer 112, reduce the possibility of damage to the support 11, and ensure the normal operation of the support assembly 10.

[0047] In some embodiments, the support 11 further includes an insulating layer, which is disposed around the outer peripheral wall of the encapsulation layer 112. The insulating layer serves two purposes: firstly, it prevents direct contact with the support 11 from causing electric shock, thus improving safety; secondly, it prevents direct contact between the support 11 and surrounding metal components or the environment from causing short circuits, ensuring the stability and reliability of the photovoltaic device 100. It should be noted that in some embodiments, the insulating layer is made of materials including, but not limited to, ceramics, plastics, rubber, and glass.

[0048] Please see Figure 1 or Figure 4 In some embodiments, the electrical component 30 includes a control module 31. Specifically, when the electrical component 30 includes an energy storage component, the control module 31 can be integrated into the energy storage component. Thus, compared to when the control module 31 is not integrated into the energy storage component, no additional communication wiring harness is required between the control module 31 and the energy storage component, thereby reducing production costs and simplifying the wiring structure of the photovoltaic device 100. It should be noted that in some embodiments, the control module 31 includes a PLC control module, etc.

[0049] Furthermore, in some embodiments, the photovoltaic device 100 further includes an electronic component 40 and a modem, the modem being electrically connected to the electronic component 40 and configured to be connected to the control module 31 via the bracket 11. It should be noted that in some embodiments, the modem includes a PLC modem, etc.; the electronic component 40 includes at least one of a sensor, a camera, a lighting module, and an audio playback module.

[0050] Specifically, in some embodiments, the electronic component 40 can be connected to the bracket 11 via a modem to achieve a signal connection with the control module 31. That is, the photovoltaic device 100 can also use the bracket 11 as a communication line between the electronic component 40 and the control module 31 without additional wiring, thereby reducing the use of wiring harnesses and making the wiring structure of the photovoltaic device 100 simpler. This can reduce production costs and simplify the assembly operation of the photovoltaic device 100.

[0051] In this system, after the electronic component 40 collects data, it can transmit signals to the bracket 11 via a modem, and then to the control module 31 via the bracket 11. The control module 31 can receive the signals transmitted from the modem through the bracket 11 and issue control commands based on the received signals to control the operation of the electrical component 30 or the electronic component 40. It should be noted that in some embodiments, a power line coupler may be provided on the bracket 11 to separate power and communication signals, thereby reducing interference.

[0052] In some embodiments, the photovoltaic device 100 further includes an anti-interference component, which is disposed on the support 11 and is used to ensure stable transmission of communication signals between the control module 31 and the modem on the support 11. Therefore, the inclusion of the anti-interference component enhances the anti-interference capability of the communication signals, prevents data loss and other problems caused by interference during transmission of the communication signals on the support 11, and improves the stability and reliability of communication between the control module 31 and the modem.

[0053] In some embodiments, the anti-interference component is made of an anti-interference material. It should be noted that in some embodiments, the anti-interference material can be aluminum, tin-plated copper, nickel-zinc ferrite, or conductive coatings containing silver, copper, or graphene, etc., and this application is not limited to these. For example, the anti-interference component can be aluminum foil, which is wrapped around the outermost part of the bracket 11 to achieve shielding protection for communication signals within the bracket 11.

[0054] In other embodiments, the anti-interference component is used to perform signal conversion on the communication signal to improve its anti-interference capability during transmission. For example, the anti-interference component can convert the communication signal between differential and single-ended signals.

[0055] Please see Figure 1 or Figure 4 and combined Figure 6 In some embodiments, the photovoltaic device 100 further includes a connection assembly 70, which includes a first connector 71 and a second connector 73. The first connector 71 is electrically connected to the photovoltaic module 20, and the second connector 73 is electrically connected to the support frame 11. The first connector 71 and the second connector 73 cooperate to electrically connect the photovoltaic module 20 to the support frame 11. It should be noted that in some embodiments, the first connector 71 is made of a conductive material.

[0056] Specifically, in some embodiments, the first connector 71 includes a first sub-part 711 and a second sub-part 713 that are in contact with each other. The first sub-part 711 is installed on the periphery of the photovoltaic module 20, and the second sub-part 713 is connected to the first sub-part 711 and electrically connected to the photovoltaic module 20. The bracket 11 is provided with a mounting groove 1101, and the second connector 73 is disposed in the mounting groove 1101. When the photovoltaic module 20 is installed in the mounting groove 1101, at least a portion of the first sub-part 711 is located in the mounting groove 1101, and the first sub-part 711 can be electrically connected to the second connector 73, thereby realizing the electrical connection between the photovoltaic module 20 and the bracket 11. It should be noted that in some embodiments, the second sub-part 713 elastically abuts against the photovoltaic module 20 to realize the electrical connection. For example, the second sub-part 713 can be a spring clip; the second connector 73 may include, but is not limited to, a pogo pin.

[0057] More specifically, in some embodiments, the structural strength of the first sub-part 711 is greater than that of the second sub-part 713. As a result, the first sub-part 711 is less likely to be deformed or damaged, thereby ensuring the stability of the connection between the first sub-part 711 and the photovoltaic module 20 and reducing the possibility of the second sub-part 713 connected to the first sub-part 711 falling off the photovoltaic module 20. This, in turn, improves the stability and reliability of the connection between the first connector 71 and the photovoltaic module 20.

[0058] Please see Figure 1 and Figure 2 ,or Figure 4 and Figure 5 In some embodiments, the multiple supports 11 include multiple frames 115 and multiple columns 116. The multiple frames 115 are used together to support the photovoltaic module 20. The upper end of the column 116 is connected to two adjacent frames 115, and the lower end of the column 116 is connected to the surface to be fixed.

[0059] It is understood that the frame 115 is a structure in the support assembly 10 used for mounting and fixing the photovoltaic module 20. In some embodiments of this application, multiple frames 115 enclose a first space 101, which is used to install the photovoltaic module 20. In other words, the photovoltaic module 20 can be installed in the first space 101 formed by multiple frames 115 connected end to end. Specifically, one of the two frames 115 forming the first space 101 has a mounting groove 1101 on its side facing inward of the first space 101, and the other has a loading frame 13 on its side facing inward of the first space 101. In this case, one side of the photovoltaic module 20 is disposed in the mounting groove 1101, and the other side is supported on the loading frame 13, thereby realizing the installation of the photovoltaic module 20 on the support assembly 10.

[0060] The cross-sectional shape of the first space 101 may include, but is not limited to, regular or irregular shapes such as square, circle, triangle and rhombus. For example, the cross-sectional shape of the first space 101 may be square, and the border 115 may include four, and the four borders 115 together enclose the first space 101.

[0061] The uprights 116 are structures in the support assembly 10 used to fix and support the entire support assembly 10. For example, when the cross-sectional shape of the first space 101 is square, four uprights 116 may be included, with each upright 116 positioned at one of the four corners of the first space 101, thereby providing stable support for the frame 115. It is understood that the surface to be fixed includes, but is not limited to, the ground or a roof. In one example, the uprights 116 have a fixed length. In another example, the uprights 116 are telescopic structures; for example, the uprights 116 may include at least two sub-posts that are telescopically connected together, allowing the user to adjust the distance between the frame 115 and the surface to be fixed according to specific usage requirements.

[0062] In one example, the multiple columns 116 are of the same length. Therefore, when the gravity and / or external load of the photovoltaic module 20 acts on the columns 116, the multiple columns 116 can more evenly transmit and distribute the pressure, achieving a uniform pressure distribution, thereby improving the structural stability of the supporting module 10. In another example, at least some of the multiple columns 116 are of different lengths. Therefore, columns 116 of appropriate length can be selected according to the actual usage environment of the photovoltaic device 100, thereby improving the applicability of the photovoltaic device 100. For example, when the cross-sectional shape of the first space 101 is rectangular, the two columns 116 connected to the frame 115 forming the short side of the first space 101 are of different lengths, while the two columns 116 connected to the frame 115 forming the long side of the first space 101 are of the same length. This allows the photovoltaic module 20 to tilt relative to the horizontal plane (the plane perpendicular to the direction of gravity).

[0063] Further, please refer to Figure 4 and Figure 5 In some embodiments, the plurality of brackets 11 further include at least two support columns 118, the support columns 118 being disposed between two adjacent columns 116, the upper end of the support column 118 being connected to the frame 115, and the lower end of the support column 118 being connected to the surface to be fixed.

[0064] If the support component 10 only includes columns 116, and the size of the first space 101 formed by multiple frames 115 is large, the frames 115 will be more easily deformed and damaged under the gravity and / or external load of the photovoltaic module 20, especially the frames 115 forming the long side of the first space 101. Therefore, in some embodiments of this application, the support column 118 is disposed between two adjacent columns 116, with the upper end of the support column 118 connected to the frame 115 and the lower end of the support column 118 connected to the surface to be fixed. That is, the support column 118 can at least support the frame 115 forming the long side of the first space 101, thereby reducing the possibility of the frame 115 deforming and being damaged under the gravity and / or external load of the photovoltaic module 20, and thus improving the structural stability of the photovoltaic device 100.

[0065] Please see Figure 1 or Figure 4 In some embodiments, the lower end of the column 116 is provided with a grounding element 80, which is electrically connected to the column 116 and is used for grounding.

[0066] Specifically, the lower end of the column 116 is also provided with a grounding component 80 electrically connected to the column 116. The lightning current conducted to the column 116 can be conducted to the grounding component 80 at the lower end of the column 116. Since the grounding component 80 is in contact with the ground, the lightning current will eventually be conducted to the ground through the grounding component 80, thereby avoiding excessive accumulation of lightning current on the photovoltaic device 100 and preventing damage to the various components of the photovoltaic device 100.

[0067] Furthermore, in some embodiments, the lower end of the column 116 is also provided with a cover 90, at least a portion of which surrounds the side wall of the lower end of the column 116. The grounding member 80 is housed in the space formed by the cover 90 and the side wall of the lower end of the column 116, thereby preventing the grounding member 80 from being exposed to the outside world and causing visual defects, and improving the aesthetics of the photovoltaic device 100.

[0068] Please see Figure 1 and Figure 2 ,or Figure 4 and Figure 5 In some embodiments, the multiple supports 11 also include crossbeams 117, the opposite ends of which are connected to two opposite frames 115 respectively, and divide the first space 101 into multiple second spaces 103, the second spaces 103 being used to install photovoltaic modules 20.

[0069] The crossbeam 117 is a structure in the support assembly 10 that serves to strengthen and support the structure. The crossbeam 117 connects two opposing frame frames 115 to form a stable support structure, thereby facilitating more stable mounting of the photovoltaic module 20. Specifically, the crossbeam 117 divides the first space 101 into multiple second spaces 103, allowing the photovoltaic module 20 to be independently installed and supported within the second spaces 103. This not only improves the stability of the photovoltaic device 100 but also more effectively utilizes the overall space enclosed by the multiple frame frames 115 (i.e., the first space 101), maximizing the number of photovoltaic modules 20 that can be installed and increasing the power generation capacity of the photovoltaic device 100.

[0070] It is understood that in some embodiments, one of the two opposing supports 11 (beams 117 and frames 115; or, two beams 117) forming the second space 103 has a mounting groove 1101 on its side facing inwards from the second space 103, and the other has a loading rack 13 on its side facing inwards from the second space 103. In this case, one side of the photovoltaic module 20 is disposed in the mounting groove 1101, and the other side is supported on the loading rack 13, thereby realizing the installation of the photovoltaic module 20 on the support assembly 10.
