Description

Technical Field

[0001] This utility model relates to the field of photovoltaic tile technology, and more specifically, to a photovoltaic tile and a photovoltaic system. Background Technology

[0002] As an important component of building-integrated photovoltaics (BIPV), photovoltaic (PV) roof tiles are often designed with complex geometric shapes that incorporate multiple orientations in order to integrate with the building's form. In such PV tiles, the power generation components, positioned at different tilt angles or azimuth angles, will receive varying levels of sunlight during actual operation, resulting in significant shifts in their respective current-voltage characteristic curves.

[0003] In related technologies, these power generation components located at different angles of sunlight are typically connected in the same series circuit. Due to the fundamental characteristics of a series circuit, the current flowing through all power generation components must remain consistent. This results in the operating current of the entire circuit being limited by the component with the weakest power generation capacity, while the components with higher power generation capacity cannot fully utilize their efficiency, leading to a severe current mismatch problem and significantly reducing the overall power generation efficiency of the photovoltaic tile. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the first aspect of this utility model proposes a photovoltaic tile.

[0006] The second aspect of this utility model proposes a photovoltaic system.

[0007] In view of the above, the first aspect of this utility model provides a photovoltaic tile, comprising: a supporting component; a first power generation component disposed on the supporting component, the first power generation component including a first positive electrode and a first negative electrode, the first power generation component forming an electrical circuit with the component to be connected through the first positive electrode and the first negative electrode; a second power generation component disposed on the supporting component, and the second power generation component having a different light-receiving angle from the first power generation component; the second power generation component including a second positive electrode and a second negative electrode, the second power generation component forming an electrical circuit with the component to be connected through the second positive electrode and the second negative electrode.

[0008] The photovoltaic tile of this invention mainly includes a supporting component, a first power generation component, and a second power generation component. The supporting component, as the load-bearing foundation of the photovoltaic tile, not only provides mechanical support, but its geometry also determines the spatial arrangement of the two power generation components. Both the first and second power generation components are fixedly mounted on the supporting component, but due to the specific structural design of the supporting component, their light-receiving angles are fundamentally different.

[0009] The difference in light reception angles can manifest in spatial orientation, with the two power generation components facing different azimuth angles. Furthermore, their tilt angles relative to the horizontal plane differ. Under identical sunlight conditions, the intensity of solar radiation received by the two power generation components, the angle of incidence of sunlight, and the effective power generation duration all exhibit significant differences. This difference directly leads to a noticeable shift in the current-voltage characteristic curves of the two power generation components, resulting in different output current magnitudes.

[0010] To address the above issues, this invention features a specially designed electrical connection architecture. The first power generation component forms an electrical circuit with the component to be connected via a first positive and a first negative terminal. Similarly, the second power generation component forms another independent electrical circuit with the component to be connected via a second positive and a second negative terminal. These four components are physically isolated from each other and electrically, constituting two independent current output paths.

[0011] Optionally, the component to be connected can be another photovoltaic tile to form a series or parallel photovoltaic array, the component to be connected can be an energy storage device to realize the storage and dispatch of electrical energy, or the component to be connected can be an electrical device to directly provide power. The two power generation components are connected to the component to be connected through their respective independent electrical circuits, ensuring efficient energy transmission and utilization in different application scenarios.

[0012] During operation, the two power generation components work independently based on their respective actual received sunlight conditions. The electrical energy generated by the first power generation component forms a first current path through the first positive and first negative terminals, while the electrical energy generated by the second power generation component forms a second current path through the second positive and second negative terminals. These two current paths maintain electrical isolation from the power source to the output terminal, ensuring no interference between them. Compared to related technologies that connect power generation components with different light-receiving angles in series, this invention solves the "weakest link" problem caused by current mismatch. Each power generation component can operate near its own maximum power point, and in photovoltaic tile applications with complex structures such as curved surfaces, this invention can effectively improve overall power generation efficiency.

Detailed Implementation

[0040] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0041] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0042] The following is combined with Figures 1 to 9 This invention describes a photovoltaic tile 100 and a photovoltaic system 10.

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in an embodiment of this utility model, a photovoltaic tile 100 is proposed, including: a support component 110, a first power generation component 130, and a second power generation component 140. The first power generation component 130 is disposed on the support component 110, and includes a first positive electrode 132 and a first negative electrode 134. The first power generation component 130 forms an electrical circuit with the component 20 to be connected through the first positive electrode 132 and the first negative electrode 134. The second power generation component 140 is disposed on the support component 110, and the light-receiving angle of the second power generation component 140 is different from that of the first power generation component 130. The second power generation component 140 includes a second positive electrode 142 and a second negative electrode 144, and forms an electrical circuit with the component 20 to be connected through the second positive electrode 142 and the second negative electrode 144.

[0044] In this embodiment, the present invention provides a photovoltaic tile 100, which aims to solve the problem of power generation efficiency loss caused by differences in the angle of light reception in the prior art.

[0045] The photovoltaic tile 100 of this utility model mainly comprises three core parts: a supporting component 110, a first power generation component 130, and a second power generation component 140. The supporting component 110, as the load-bearing foundation of the photovoltaic tile 100, not only provides mechanical support, but its geometric shape also determines the spatial arrangement of the two power generation components. Both the first power generation component 130 and the second power generation component 140 are fixedly mounted on the supporting component 110, but due to the specific structural design of the supporting component 110, their light-receiving angles are fundamentally different.

[0046] Specifically, the difference in light reception angles can be reflected in the spatial orientation, with the two power generation components facing different azimuth angles. Furthermore, their tilt angles relative to the horizontal plane differ. Under the same sunlight conditions, the intensity of solar radiation received by the two power generation components, the angle of incidence of sunlight, and the effective power generation duration all exhibit significant differences. This difference directly leads to a significant shift in the current-voltage characteristic curves of the two power generation components, resulting in different output current magnitudes.

[0047] To address the above issues, this invention features a specially designed electrical connection architecture. The first power generation component 130 forms an electrical circuit with the component 20 to be connected via its first positive terminal 132 and first negative terminal 134. Similarly, the second power generation component 140 forms another independent electrical circuit with the component 20 to be connected via its second positive terminal 142 and second negative terminal 144. These four components are physically and electrically isolated from each other, constituting two independent current output paths.

[0048] Optionally, the component to be connected 20 can be another photovoltaic tile 100 to form a series or parallel photovoltaic array, can be an energy storage device to realize the storage and scheduling of electrical energy, or can be an electrical device to directly provide power; the two power generation components are connected to the component to be connected 20 through their respective independent electrical circuits, ensuring that efficient energy transmission and utilization can be achieved in different application scenarios.

[0049] During operation, the two power generation components work independently based on their respective actual received lighting conditions. The electrical energy generated by the first power generation component 130 forms a first current path through the first positive terminal 132 and the first negative terminal 134, while the electrical energy generated by the second power generation component 140 forms a second current path through the second positive terminal 142 and the second negative terminal 144. These two current paths maintain electrical isolation from the power source to the output terminal and do not interfere with each other.

[0050] Compared to related technologies that connect power generation components with different light-receiving angles in series, this invention solves the "weakest link" problem caused by current mismatch. Each power generation component can operate near its own maximum power point. In photovoltaic tile applications with complex structures such as curved surfaces, this invention can effectively improve the overall power generation efficiency.

[0051] The photovoltaic tile 100 proposed in this utility model can be widely used in various photovoltaic tile 100 products that need to adapt to complex building shapes, and its effect is particularly significant in scenarios such as large curvature photovoltaic barrel tiles with curved surface structures.

[0052] Specifically, such as Figure 1 As shown, the photovoltaic tile includes a power generation layer 120, which includes a first power generation component 130 and a second power generation component 140. The present invention splits the series power generation layer in the related technology to form an independent first power generation component 130 and a second power generation component 140.

[0053] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in some embodiments of the present invention, optionally, the support member 110 is arc-shaped, and the side of the support member 110 away from the center is an outer arc surface 210. Along the bending direction of the outer arc surface 210, the outer arc surface 210 includes a first arc surface 212 and a second arc surface 214. The first power generation member 130 is disposed on the first arc surface 212, and the second power generation member 140 is disposed on the second arc surface 214.

[0054] In this embodiment, the support member 110 is constructed as an arc-shaped structure. The arc-shaped support member 110 can better adapt to the curved shape requirements of the building roof. At the same time, by arranging the two power generation components on different sides of the arc, solar radiation energy from different directions can be fully utilized.

[0055] The side of the support component 110 opposite to the center is the outer arc surface 210, and along the bending direction of the outer arc surface 210 (e.g. Figure 4 (In the direction indicated by arrow A), the outer arc surface 210 includes a first arc surface 212 and a second arc surface 214. The first power generation component 130 is disposed on the first arc surface 212, and the second power generation component 140 is disposed on the second arc surface 214. In the photovoltaic tile 100 with an arc-shaped structure, the first power generation component 130 and the second power generation component 140 naturally have different light-receiving angles. This utility model effectively avoids the loss of power generation efficiency caused by the different light-receiving angles by completely isolating the two power generation components electrically. Specifically, the first power generation component 130 forms an electrical circuit with the component 20 to be connected through its first positive electrode 132 and first negative electrode 134, and the second power generation component 140 forms another independent electrical circuit with the component 20 to be connected through its second positive electrode 142 and second negative electrode 144. These four positive and negative electrodes constitute two completely independent power output channels, ensuring that the current generated by the power generation components on both sides can be collected separately without interference.

[0056] Specifically, the photovoltaic tile 100 is a photovoltaic barrel tile, with the supporting component 110 being arc-shaped and the outer arc surface 210 serving as the main light-receiving surface. The outer arc surface 210 includes a first arc surface 212 and a second arc surface 214. The first power generation component 130 is located on the first arc surface 212, and the second power generation component 140 is located on the second arc surface 214. The photovoltaic barrel tile has a large curvature, which results in a significant difference in the light-receiving angle between the power generation components located on the two arc surfaces, thereby exacerbating the current mismatch problem in the series connection method. This utility model, by setting independent positive and negative poles for the two power generation components to form their own independent electrical circuits, can still ensure the independent output of electrical energy from the two power generation units under large curvature conditions, effectively avoiding the loss of power generation efficiency caused by uneven illumination conditions on both sides of the curved surface.

[0057] It should be noted that the photovoltaic tile 100 proposed in this invention has good adaptability to various shapes of support components 110. Besides the arc-shaped structure, the support component 110 can also adopt other geometric shapes, such as triangles, polygons, and waves. These different shaped support components 110 all allow the two power generation components mounted on them to have different light-receiving angles. Furthermore, this invention, through its design of four independent positive and negative electrodes, ensures that the output of the two power generation components does not interfere with each other under any circumstances, thus maintaining optimal power generation efficiency at all times.

[0058] For example, the support member 110 has a triangular structure, including two adjacent inclined surfaces. The first power generation member 130 is disposed on one inclined surface, and the second power generation member 140 is disposed on the other inclined surface. The two power generation members output electrical energy through their respective independent positive and negative terminals.

[0059] For example, the support component 110 has a stepped structure, including multiple mounting planes at different heights. The first power generation component 130 is disposed on the lower mounting plane, and the second power generation component 140 is disposed on the upper mounting plane. Through independent positive and negative terminal configurations, the electrical energy of the two power generation components is output through dedicated channels, effectively avoiding power generation efficiency loss caused by differences in installation height.

[0060] For example, the support component 110 has a wave-shaped structure, including continuous crests and troughs. The first power generation component 130 is disposed on the surface at the crest, and the second power generation component 140 is disposed on the surface at the trough. The complete electrical isolation between the two power generation components ensures that each can operate under optimal conditions, improving the environmental adaptability and power generation stability of the wave-shaped photovoltaic tile.

[0061] The photovoltaic tile 100 proposed in this utility model effectively solves the current matching problem of the power generation components on the support components 110 of different shapes by adopting a design of four independent positive and negative electrodes.

[0062] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments of the present invention, optionally, the first power generation component 130 and the second power generation component 140 are symmetrically distributed about the central axis of the support component 110.

[0063] In this embodiment, the first power generation component 130 and the second power generation component 140 are about the central axis of the support component 110 (e.g., Figure 4As shown by line B, the two power generation components are symmetrically distributed, arranged on both sides of the central axis of the support component 110, forming a mirror-symmetrical layout. This symmetrical layout ensures balanced stress on the support component 110, improving the structural stability and lifespan of the photovoltaic tile 100. Furthermore, the symmetrical arrangement allows for better light absorption uniformity within each power generation component, ensuring relatively uniform illumination for each cell and resulting in more uniform and stable power output.

[0064] In this embodiment, the present invention optimizes the power generation uniformity within each power generation component through symmetrical arrangement, and effectively eliminates the mutual influence between two power generation components by combining four independent electrical isolation architectures. The photovoltaic tile 100 proposed by the present invention retains the structural advantages of symmetrical layout while fully leveraging the technical benefits of electrical isolation. In actual operation, even if the two power generation components have different output characteristics due to differences in the angle of light received, the power generation performance of the two components will not restrict each other. Each power generation component can operate independently under optimal working conditions, thereby significantly improving the overall power generation efficiency of the photovoltaic tile 100.

[0065] Optionally, the first power generation component 130 is arranged in a uniformly distributed manner on one side of the arc surface of the supporting component 110. The multiple first battery cells 139 included in the first power generation component 130 are arranged at equal intervals according to the curvature characteristics of the arc surface, ensuring that a reasonable center distance is maintained between adjacent first battery cells 139. The uniformly distributed layout allows all first battery cells 139 on the same side of the arc surface to obtain a consistent illumination angle and radiation intensity, effectively avoiding the problem of uneven light reception caused by positional differences.

[0066] Similarly, the second power generation component 140 also adopts the same uniform distribution design on the other side of the arc surface of the support component 110, ensuring that the second battery cell 149 on that side obtains optimal light-receiving conditions. Although the two power generation components are distributed on different arc surfaces and have different light-receiving angle characteristics, their internal uniform distribution achieves performance optimization of the power generation unit.

[0067] Optionally, the support component 110 is arc-shaped, and the symmetrical distribution specifically refers to its arrangement around the center line of the arc surface of the arc-shaped support component 110 as the axis of symmetry. The center line of the arc surface is a virtual reference line extending longitudinally along the arc surface, dividing the entire arc surface into two completely symmetrical parts. The first power generation component 130 and the second power generation component 140 are arranged symmetrically on both sides of this center line, forming a mirror image relationship. This arrangement method of using the center line of the arc surface as the axis of symmetry not only ensures the overall structural balance and aesthetics of the photovoltaic tile 100, but also enables the two power generation components to obtain relatively balanced power generation capacity under the same environmental conditions.

[0068] like Figure 2 As shown, in some embodiments of this utility model, optionally, the photovoltaic tile 100 further includes: a first junction box 150, the first junction box 150 including a first positive lead-out terminal 152 and a second positive lead-out terminal 154, the first positive lead-out terminal 152 being electrically connected to the first positive electrode 132, and the second positive lead-out terminal 154 being electrically connected to the second positive electrode 142; and a second junction box 160, the second junction box 160 including a first negative lead-out terminal 162 and a second negative lead-out terminal 164, the first negative lead-out terminal 162 being electrically connected to the first negative electrode 134, and the second negative lead-out terminal 164 being electrically connected to the second negative electrode 144.

[0069] In this embodiment, the photovoltaic tile 100 also includes a first junction box 150 and a second junction box 160. The present invention achieves complete independence of the energy output of the two power generation components through the junction box design.

[0070] The first junction box 150 is used for current collection and transmission. The first junction box 150 has two completely independent leads inside. The first positive lead 152 is electrically connected to the first positive terminal 132 of the first power generation component 130, and the second positive lead 154 is electrically connected to the second positive terminal 142 of the second power generation component 140. The currents of the two power generation components are electrically isolated within the first junction box 150, ensuring that the currents do not mix.

[0071] Accordingly, the second junction box 160, used for current collection and transmission, also has two independent leads. The first negative lead 162 is electrically connected to the first negative lead 134 of the first power generation component 130, and the second negative lead 164 is electrically connected to the second negative lead 144 of the second power generation component 140. These two negative leads are also electrically isolated inside the second junction box 160.

[0072] Through the first junction box 150 and the second junction box 160, this invention establishes a completely independent dual-output system. The current generated by the first power generation component 130 forms a complete electrical circuit through the first positive terminal 132 → the first positive terminal 152 of the first junction box 150, and the first negative terminal 134 → the first negative terminal 162 of the second junction box 160. The current generated by the second power generation component 140 forms an independent electrical circuit through the second positive terminal 142 → the second positive terminal 154 of the first junction box 150, and the second negative terminal 144 → the second negative terminal 164 of the second junction box 160. The currents of the two power generation components are completely isolated from generation to output, forming a truly independent dual-output architecture. In actual operation, even if the two power generation components produce significantly different output currents due to different light angles, the "weakest link" effect found in series circuits in related technologies will not occur. Each power generation component can operate at its optimal operating point, thereby significantly improving the overall power generation efficiency of the photovoltaic tile 100. Especially in the application of large curvature photovoltaic barrel tiles, it effectively solves the problem of power generation efficiency loss caused by uneven light exposure on both sides of the curved surface.

[0073] like Figure 4 As shown, in some embodiments of this utility model, optionally, the photovoltaic tile 100 further includes: a third junction box 170, the third junction box 170 including a third positive lead-out terminal 172, the third positive lead-out terminal 172 being electrically connected to a first positive terminal 132; a fourth junction box 180, the fourth junction box 180 including a fourth positive lead-out terminal 182, the fourth positive lead-out terminal 182 being electrically connected to a second positive terminal 142; a fifth junction box 190, the fifth junction box 190 including a third negative lead-out terminal 192, the third negative lead-out terminal 192 being electrically connected to a first negative terminal 134; and a sixth junction box 194, the sixth junction box 194 including a fourth negative lead-out terminal 196, the fourth negative lead-out terminal 196 being electrically connected to a second negative terminal 144.

[0074] In this embodiment, the photovoltaic tile 100 adopts a design with four independent junction boxes, with a dedicated junction box configured for each positive and negative electrode, thus optimizing the manufacturing process.

[0075] In this embodiment, the photovoltaic tile 100 further includes a third junction box 170, a fourth junction box 180, a fifth junction box 190, and a sixth junction box 194. The third junction box 170 is used for the positive output of the first power generation component 130. The third junction box 170 includes a third positive lead-out terminal 172 and is electrically connected to the first positive terminal 132.

[0076] The fourth junction box 180 is used for the positive output of the second power generation component 140, and the fourth positive lead 182 of the fourth junction box 180 is directly electrically connected to the second positive lead 142. The fifth junction box 190 is used for the negative circuit of the first power generation component 130, and the third negative lead 192 is directly electrically connected to the first negative lead 134. The sixth junction box 194 is used for the negative circuit of the second power generation component 140, and the fourth negative lead 196 of the sixth junction box 194 is directly electrically connected to the second negative lead 144.

[0077] In this embodiment, the configuration of four junction boxes in this invention has significant advantages in manufacturing process. Each junction box only needs to handle a single connection task, greatly simplifying the internal structure design and production process of the junction boxes. During manufacturing, each junction box can be installed and wired independently, effectively improving production efficiency and assembly quality.

[0078] In terms of electrical performance, this invention ensures completely independent output from the two power generation components. The first power generation component 130 forms an independent electrical circuit through the third junction box 170 and the fifth junction box 190, and the second power generation component 140 forms an independent electrical circuit through the fourth junction box 180 and the sixth junction box 194. The complete physical isolation between the four junction boxes fundamentally eliminates the possibility of electrical interference between different power generation circuits.

[0079] like Figure 1 As shown, in some embodiments of the present invention, optionally, the support component 110 includes a base plate 112 and a cover plate 114, the first power generation component 130 and the second power generation component 140 are disposed on the base plate 112; the cover plate 114 covers the first power generation component 130 and the second power generation component 140.

[0080] In this embodiment, the support component 110 includes a base plate 112 and a cover plate 114. The base plate 112 serves as the basic load-bearing structure, and the first power generation component 130 and the second power generation component 140 are directly disposed on the surface of the base plate 112. The cover plate 114 is light-transmitting and covers the two power generation components, forming a protective enclosure.

[0081] Specifically, the cover plate 114 is made of single-curved tempered glass, with a thickness controlled within the range of 2 mm to 5 mm and a light transmittance of not less than 90%. Through the design of the aforementioned materials, thickness, and light transmittance, both sufficient mechanical strength and weather resistance of the cover plate 114 are ensured, while also guaranteeing ample light transmittance to provide optimal lighting conditions for the power generation components. Besides single-curved tempered glass, other rigid polymer materials with equivalent optical properties and mechanical strength can also be selected as the cover plate material.

[0082] The base plate 112 of the supporting component 110 can be made of photovoltaic-grade backsheet material or other high-performance polymer materials. The main function of the base plate 112 is to provide reliable mechanical protection and electrical insulation for the internal power generation components, ensuring that the power generation components maintain stable operating performance during long-term use.

[0083] Optionally, the cover plate 114 adopts a large curvature bending design. This special bending structure allows the first power generation component 130 and the second power generation component 140 located on both sides of the cover plate 114 to have significantly different light-receiving angles. They reach their power generation peaks at different times of the day. Through the unique four independent designs of this invention, even with such significant differences in light-receiving angles, the two power generation components will not experience a current-limiting effect, thus ensuring that their respective power generation efficiency is unaffected.

[0084] In the manufacturing process, single-curved tempered glass is first formed into the required curved cover plate using a hot bending process. Then, the first power generation component 130 and the second power generation component 140 are precisely positioned on the inner surface of the curved cover plate according to the principle of symmetrical distribution. The layout of the power generation components needs to fully consider the curvature characteristics of the cover plate 114 to ensure that the solar cells in each power generation component can obtain the optimal light-receiving angle. Next, the flexible base plate is laminated with the power generation components, so that the base plate 112 and the cover plate 114 form a matching curved surface structure, ultimately forming a complete photovoltaic tile.

[0085] like Figure 1 As shown, in some embodiments of this utility model, optionally, the support component 110 further includes a first adhesive layer 116 and a second adhesive layer 118. The first adhesive layer 116 is provided between the first power generation component 130 and the cover plate 114, and the first adhesive layer 116 is provided between the second power generation component 140 and the cover plate 114; the second adhesive layer 118 is provided between the first power generation component 130 and the base plate 112, and the second adhesive layer 118 is provided between the second power generation component 140 and the base plate 112.

[0086] In this embodiment, the support component 110 further includes a first adhesive layer 116 disposed between the cover plate 114 and the power generation component, and a second adhesive layer 118 disposed between the power generation component and the base plate 112. These two adhesive layers together constitute a complete encapsulation system, providing reliable structural stability and long-term durability for the photovoltaic tile 100.

[0087] In practice, both the first adhesive layer 116 and the second adhesive layer 118 use encapsulating film materials specifically designed for photovoltaic modules. These encapsulating films can be selected from photovoltaic industry-proven encapsulating materials such as POE (polyolefin elastomer), EVA (ethylene-vinyl acetate copolymer), PVB (polyvinyl butyral), or silicone.

[0088] like Figure 2 and Figure 3 As shown, in some embodiments of this utility model, optionally, the first power generation component 130 includes at least two rows of battery strings connected in parallel, each row of battery strings being composed of multiple first battery cells 139 connected in series. Specifically, the positive terminals of each row of battery strings are connected to the first positive terminal 132, and the negative terminals of each row of battery strings are connected to the first negative terminal 134, thereby improving the output current capability of the first power generation component 130 through the parallel structure, and forming an electrical circuit with the component 20 to be connected through the first positive terminal 132 and the first negative terminal 134.

[0089] Specifically, when the battery strings are arranged in two rows, the first power generation component 130 includes a first battery string 136 and a second battery string 138. Both the first battery string 136 and the second battery string 138 are composed of multiple first battery cells 139 connected in series. One end of the first battery string 136 is connected to one end of the second battery string 138, and both are connected to the first positive terminal 132. The other end of the first battery string 136 is connected to the other end of the second battery string 138, and both are connected to the first negative terminal 134. This parallel structure design allows the current output from the two battery strings to converge to the corresponding terminals, which not only improves the output current capability but also ensures a stable output of electrical energy through the first positive terminal 132 and the first negative terminal 134.

[0090] like Figure 2 and Figure 3 As shown, in some embodiments of this utility model, optionally, the second power generation component 140 includes at least two rows of battery strings connected in parallel, each row of battery strings being composed of multiple second battery cells 149 connected in series. Specifically, the positive terminals of each row of battery strings are connected to a second positive terminal 142, and the negative terminals of each row of battery strings are connected to a second negative terminal 144, thereby improving the output current capability of the second power generation component 140 through the parallel structure, and forming an electrical circuit with the component 20 to be connected through the second positive terminal 142 and the second negative terminal 144.

[0091] Specifically, when the battery strings are arranged in two rows, the second power generation component 140 includes a third battery string 146 and a fourth battery string 148, both of which are composed of multiple second battery cells 149 connected in series. One end of the third battery string 146 is connected to one end of the fourth battery string 148, and both are connected to the second positive terminal 142. The other end of the third battery string 146 is connected to the other end of the fourth battery string 148, and both are connected to the second negative terminal 144. This parallel structure design allows the current output from the two battery strings to be converged to the corresponding positive and negative terminals, which not only improves the output current capability but also ensures a stable output of electrical energy through the second positive terminal 142 and the second negative terminal 144.

[0092] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in an embodiment of the present invention, a photovoltaic system 10 is proposed, which includes photovoltaic tiles 100 as described in any of the above embodiments.

[0093] In this embodiment, the photovoltaic system 10 proposed by this utility model includes the photovoltaic tile 100 as in any of the above embodiments, and therefore has all the beneficial effects of the photovoltaic tile 100 in any of the above embodiments.

[0094] In this embodiment, by employing photovoltaic tiles 100 with four independent positive and negative electrodes, the photovoltaic system 10 effectively solves the problem of power generation efficiency loss caused by current mismatch of power generation components at different light-receiving angles in curved photovoltaic tiles. The first power generation component 130 and the second power generation component 140 each form an electrical circuit with the component 20 to be connected through independent positive and negative electrodes, achieving completely independent operation. Even if the two power generation components have different output currents due to differences in light-receiving angles, there will be no mutual constraint effect, thus ensuring that both power generation components can continuously generate electricity at their respective highest efficiency, significantly improving the overall power generation efficiency of the photovoltaic system 10.

[0095] Optionally, the photovoltaic system 10 can provide power to various electrical devices or be used in conjunction with energy storage devices. Specifically, the electricity generated by the photovoltaic system 10 can directly power indoor electrical devices, including lighting systems, air conditioning systems, and other everyday electrical devices, or provide independent power to outdoor facilities such as streetlights and monitoring equipment. When used in conjunction with energy storage devices, the electricity generated by the system can be stored in various battery banks, supercapacitor banks, or energy storage systems containing charge and discharge management circuits, enabling flexible scheduling and use of electrical energy.

[0096] The photovoltaic system 10 built based on photovoltaic tiles 100 not only maintains the power generation efficiency advantage of a single photovoltaic tile 100, but also realizes independent management and optimized utilization of power generation units on both sides at the system level, providing an efficient and reliable energy solution for various application scenarios.

[0097] like Figure 4 , Figure 5 and Figure 6As shown, in some embodiments of this utility model, optionally, there are multiple photovoltaic tiles 100, and multiple photovoltaic tiles 100 are connected in sequence to form a photovoltaic tile string 200; in the photovoltaic tile string 200, multiple first power generation components 130 are connected in series, and multiple second power generation components 140 are connected in series; wherein, all the first power generation components 130 are located on the first side 202 of the photovoltaic tile string 200, and all the second power generation components 140 are located on the second side 204 of the photovoltaic tile string 200.

[0098] In this embodiment, the photovoltaic system 10 expands its capacity by connecting multiple photovoltaic tiles 100 in series to form a photovoltaic tile string 200. Within each photovoltaic tile string 200, all first power generation components 130 are connected in series to form a power generation link on one side, and all second power generation components 140 are connected in series to form a power generation link on the other side.

[0099] In this embodiment, there are no direct electrical connection points between the two links, ensuring that the current generated by the power generation components on both sides is completely independent and uncoupled throughout the entire path from the source to the convergence point. Therefore, even if there are significant differences in the output current of the two links due to different light angles, they will never restrict each other or form loop interference. Each link can operate at its optimal operating point based on its own real-time illumination conditions, achieving independent maximization of power generation efficiency.

[0100] like Figure 6 and Figure 7 As shown, in some embodiments of the present invention, optionally, in the photovoltaic tile string 200, for any two adjacent photovoltaic tiles 100, the first positive electrode 132 of the first power generation component 130 of one photovoltaic tile 100 is electrically connected to the first negative electrode 134 of the first power generation component 130 of the other photovoltaic tile 100, and the second positive electrode 142 of the second power generation component 140 of one photovoltaic tile 100 is electrically connected to the second negative electrode 144 of the second power generation component 140 of the other photovoltaic tile 100.

[0101] In this embodiment, to achieve series connection of power generation components on the same side, any two physically adjacent photovoltaic tiles 100 have their first power generation components 130 located on the first side 202 connected through positive and negative terminals, i.e., the first positive terminal 132 of one tile is connected to the first negative terminal 134 of the adjacent tile. Similarly, the second power generation components 140 located on the second side 204 are also independently connected in series, i.e., the second positive terminal 142 of one tile is connected to the second negative terminal 144 of the adjacent tile. This connection method of interconnection on the same side and isolation on opposite sides ensures that the power generation link on one side is completely electrically independent from the power generation link on the other side, forming two parallel but isolated current paths, fundamentally eliminating the mutual restriction of current caused by differences in light exposure.

[0102] For example, such as Figure 7As shown, taking a photovoltaic tile string 200 consisting of three photovoltaic tiles 100 connected in series as an example: the three photovoltaic tiles 100 are the first photovoltaic tile 100A, the second photovoltaic tile 100B and the third photovoltaic tile 100C.

[0103] The three photovoltaic tiles 100 are connected in a same-side interconnection manner—that is, the first negative electrode 134A of the first photovoltaic tile is connected to the first positive electrode 132B of the second photovoltaic tile, and the first negative electrode 134B of the second photovoltaic tile is connected to the first positive electrode 132C of the third photovoltaic tile, forming a circuit on one side.

[0104] Meanwhile, the second negative electrode 144A of the first photovoltaic tile is connected to the second positive electrode 142B of the second photovoltaic tile, and the second negative electrode 144B of the second photovoltaic tile is connected to the second positive electrode 142C of the third photovoltaic tile to form the other side of the circuit.

[0105] like Figure 7 and Figure 8 As shown, in some embodiments of this utility model, optionally, the photovoltaic system 10 further includes: a first positive busbar 400, electrically connected to the first positive electrode 132 of a first power generation component 130 located at one end of the photovoltaic string 200; a first negative busbar 600, electrically connected to the first negative electrode 134 of a first power generation component 130 located at the other end of the photovoltaic string 200; a second positive busbar 500, electrically connected to the second positive electrode 142 of a second power generation component 140 located at one end of the photovoltaic string 200; and a second negative busbar 700, electrically connected to the second negative electrode 144 of a second power generation component 140 located at the other end of the photovoltaic string 200.

[0106] In this embodiment, the photovoltaic system 10 is equipped with four independent buses, which are used to collect and guide the electrical energy generated by two independent power generation links. The first positive bus 400 and the first negative bus 600 together constitute the input and output bus of one side of the power generation link, and the first positive bus 400 and the first negative bus 600 are respectively connected to the two ends of the other side of the photovoltaic tile string 200 link.

[0107] The second positive bus 500 and the second negative bus 700 constitute an independent bus for the second-side power generation link, connecting the two ends of the second-side link.

[0108] Through these four busbars, the current generated by the two power generation links is collected and transmitted in complete isolation to subsequent power-consuming equipment, energy storage systems or grid connection points, realizing independent management and optimized utilization of the power generation on both sides.

[0109] like Figure 8As shown, in some embodiments of this utility model, optionally, there are multiple photovoltaic tile strings 200, multiple photovoltaic tiles 100 in the photovoltaic tile strings 200 are connected sequentially along a first direction, and multiple photovoltaic tile strings 200 are arranged at intervals along a second direction, with an included angle between the first direction and the second direction; in each photovoltaic tile string 200, along the first direction, the first positive electrode 132 of the photovoltaic tile 100 at the first end is electrically connected to the first positive electrode bus 400, and the first negative electrode 134 of the photovoltaic tile 100 at the last end is electrically connected to the first negative electrode bus 600; in each photovoltaic tile string 200, along the first direction, the second positive electrode 142 of the photovoltaic tile 100 at the first end is electrically connected to the second positive electrode bus 500, and the second negative electrode 144 of the photovoltaic tile 100 at the last end is electrically connected to the second negative electrode bus 700.

[0110] In this embodiment, a parallel array architecture for the photovoltaic system 10 is provided. Multiple photovoltaic tile strings 200 are spatially arranged along a second direction (e.g., Figure 8 The photovoltaic tile strings are arranged in the direction indicated by the middle arrow D, and each photovoltaic tile string 200 is itself along the first direction (as shown by the middle arrow D). Figure 8 The direction indicated by the middle arrow C) is formed by multiple photovoltaic tiles 100 connected in series. There is an angle between the first direction and the second direction, which are usually perpendicular to each other, thus forming an array. Specifically, the first direction is the length direction of the photovoltaic system 10, the second direction is the width direction of the photovoltaic system 10, and the angle between the first direction and the second direction is ninety degrees.

[0111] In this architecture, each photovoltaic (PV) tile string 200 is an independent power generation unit, with its first and second side links directly connected to the corresponding four common buses. Specifically, the first side link of each string is connected in parallel to the first positive bus 400 and the first negative bus 600, and the second side link of each string is connected in parallel to the second positive bus 500 and the second negative bus 700. This fully parallel design ensures electrical independence between the PV tile strings 200. When the performance of some strings degrades due to shading, dirt, or faults, it will not affect the power generation of other normal strings. The system as a whole has higher reliability and robustness, making it particularly suitable for maintaining high power generation efficiency in complex application scenarios with uneven sunlight conditions.

[0112] Exemplarily, in an embodiment of the parallel architecture of this utility model, such as Figure 8 As shown, the photovoltaic system 10 has three photovoltaic tile strings 200, namely the first photovoltaic tile string 200A, the second photovoltaic tile string 200B and the third photovoltaic tile string 200C. The first photovoltaic tile string 200A, the second photovoltaic tile string 200B and the third photovoltaic tile string 200C are arranged in parallel along the width direction of the system, and each photovoltaic tile string 200 contains three photovoltaic tiles 100.

[0113] Taking the first photovoltaic tile string 200A as an example, the first photovoltaic tile string 200A includes a first photovoltaic tile 100A, a second photovoltaic tile 100B, and a third photovoltaic tile 100C. The three photovoltaic tiles 100A are connected in a same-side interconnection manner, that is, the first negative electrode 134A of the first photovoltaic tile is connected to the first positive electrode 132B of the second photovoltaic tile, and the first negative electrode 134B of the second photovoltaic tile is connected to the first positive electrode 132C of the third photovoltaic tile, forming a one-sided circuit.

[0114] Meanwhile, the second negative electrode 144A of the first photovoltaic tile is connected to the second positive electrode 142B of the second photovoltaic tile, and the second negative electrode 144B of the second photovoltaic tile is connected to the second positive electrode 142C of the third photovoltaic tile to form another circuit.

[0115] Four busbars are connected to both ends of the photovoltaic tile string 200. The first positive busbar 400 is connected to the first positive terminal 132A of the first photovoltaic tile. The second positive busbar 500 is connected to the second positive terminal 142A of the first photovoltaic tile. The first negative busbar 600 and the second negative busbar 700 are connected to the first negative terminal 134C and the second negative terminal 144C of the third photovoltaic tile, respectively. This forms two completely independent current loops, one flowing into the positive terminal of the first photovoltaic tile 100A and the other flowing out of the negative terminal of the third photovoltaic tile 100C.

[0116] The second photovoltaic string 200B and the third photovoltaic string 200C use the exact same connection method, and are independently connected to the corresponding four busbars respectively.

[0117] Under this architecture, the individual photovoltaic strings 200 do not interfere with each other, effectively improving the overall power generation efficiency and operational reliability of the photovoltaic system 10 under complex lighting conditions.

[0118] like Figure 9 As shown, in some embodiments of this utility model, optionally, the number of photovoltaic tile strings 200 is multiple, and the multiple photovoltaic tiles 100 in the photovoltaic tile strings 200 are arranged along a first direction (e.g., Figure 9 Multiple photovoltaic tile strings 200 are connected sequentially in the direction indicated by the middle arrow C, along the second direction (as shown by the middle arrow C). Figure 9 The photovoltaic tiles are arranged at intervals (as indicated by the arrow D), with an angle between the first direction and the second direction; along the first direction, the first power generation component 130 of the photovoltaic tile 100 at the end of a photovoltaic tile string 200 is electrically connected to the first power generation component 130 of the photovoltaic tile 100 at the beginning of the adjacent photovoltaic tile string 200; along the first direction, the second power generation component 140 of the photovoltaic tile 100 at the end of a photovoltaic tile string 200 is electrically connected to the second power generation component 140 of the photovoltaic tile 100 at the beginning of the adjacent photovoltaic tile string 200.

[0119] In this embodiment, another series array architecture for the photovoltaic system 10 is provided. Multiple photovoltaic tile strings 200 are also arranged in the second direction. Unlike the parallel architecture, in this architecture, adjacent photovoltaic tile strings 200 are connected across strings via their respective first power generation components 130 and second power generation components 140. Specifically, along the first direction, the first power generation component 130 of the last photovoltaic tile 100 of the preceding photovoltaic tile string 200 is electrically connected to the first power generation component 130 of the first photovoltaic tile 100 of the following photovoltaic tile string 200, thereby connecting the first-side links of multiple photovoltaic tile strings 200 in series into a longer first-side power generation link. Similarly, the second-side links of multiple photovoltaic tile strings 200 are also connected across strings in the same way. In this way, multiple photovoltaic tile strings 200 can be further connected in series to form a larger photovoltaic tile array while maintaining internal series connection and isolation between the two sides of the circuit, to meet the needs of higher system voltage or specific topologies. Furthermore, this application strictly maintains absolute electrical isolation between the first-side link and the second-side link while ensuring internal series connection of the power generation links on both sides. Without any cross-side connection, it achieves independent current output and avoids mismatch.

[0120] Specifically, in implementing the aforementioned cross-string connection, for the first side link, the first positive terminal 132 of the first power generation component 130 of the photovoltaic tile 100 at the end of the previous string is connected to the first negative terminal 134 of the first power generation component 130 of the photovoltaic tile 100 at the beginning of the next string. For the second side link, the second positive terminal 142 of the second power generation component 140 of the photovoltaic tile 100 at the end of the previous string is connected to the second negative terminal 144 of the second power generation component 140 of the photovoltaic tile 100 at the beginning of the next string. Furthermore, this connection can also be conveniently and reliably implemented using a junction box integrated on the photovoltaic tile 100.

[0121] like Figure 9 As shown, in some embodiments of this utility model, optionally, when photovoltaic tiles 100 in a plurality of photovoltaic tile strings 200 are connected in sequence, the first power generation component 130 of the photovoltaic tile 100 at the first end is a first electrical connector 220, the first power generation component 130 of the photovoltaic tile 100 at the end is a second electrical connector 230, and a component to be connected 20 is provided between the first electrical connector 220 and the second electrical connector 230; the second power generation component 140 of the photovoltaic tile 100 at the first end is a third electrical connector 240, the second power generation component 140 of the photovoltaic tile 100 at the end is a fourth electrical connector 250, and a component to be connected 20 is provided between the third electrical connector 240 and the fourth electrical connector 250.

[0122] In this embodiment, for an array formed by multiple photovoltaic tile strings 200 connected in series, after the entire array is connected in series, for the power generation link formed by the first power generation components 130 connected in series, the current input end, i.e., the first power generation component 130 of the photovoltaic tile 100 located at the beginning of the entire array, is defined as the first electrical connector 220, and the current output end, i.e., the first power generation component 130 of the photovoltaic tile 100 located at the end of the entire array, is defined as the second electrical connector 230. An external component 20 to be connected, such as an inverter, load, or energy storage device, will be connected between the first electrical connector 220 and the second electrical connector 230 to utilize the electrical energy generated by the first side link.

[0123] Similarly, for a power generation link formed by the second power generation components 140 connected in series, the current input end, i.e., the second power generation component 140 of the photovoltaic tile 100 located at the beginning of the entire array, is defined as the third electrical connector 240, and the current output end, i.e., the second power generation component 140 of the photovoltaic tile 100 located at the end of the entire array, is defined as the fourth electrical connector 250. Another component 20 to be connected is connected between the third electrical connector 240 and the fourth electrical connector 250.

[0124] The photovoltaic system 10 of this invention, as defined above, provides physically isolated and electrically complete external interfaces for the two completely independent power generation links. This ensures that electrical energy collected from different oriented surfaces of the building, which may have different electrical characteristics due to differences in sunlight conditions, can be independently and efficiently extracted, managed, and used, fundamentally achieving system-level optimization of power generation efficiency.

[0125] Optionally, to facilitate on-site installation and wiring, the aforementioned electrical connectors can be connected to the remote component 20 to be connected via extension cables. The photovoltaic system 10 can be correspondingly configured with a first extension cable 810, a second extension cable 820, a third extension cable 830, and a fourth extension cable 840. The first extension cable 810 is used to connect the first electrical connector 220 to the terminal of the corresponding component 20 to be connected. The third extension cable 830 is used to connect the second electrical connector 230 to the terminal of the corresponding component 20 to be connected. The second extension cable 820 is used to connect the third electrical connector 240 to the terminal of the corresponding component 20 to be connected. The fourth extension cable 840 is used to connect the fourth electrical connector 250 to the terminal of the corresponding component 20 to be connected.

[0126] Specifically, when finalizing and connecting the electrical connectors, the first electrical connector 220 is typically the first positive electrode 132 of the first power generation component 130 of the photovoltaic tile 100 located at the beginning of the array. The second electrical connector 230 is the first negative electrode 134 of the first power generation component 130 of the photovoltaic tile 100 located at the end of the array. Correspondingly, the third electrical connector 240 is the second positive electrode 142 of the second power generation component 140 of the photovoltaic tile 100 located at the beginning of the array, and the fourth electrical connector 250 is the second negative electrode 144 of the second power generation component 140 of the photovoltaic tile 100 located at the end of the array.

[0127] Furthermore, the connection between the aforementioned electrical connectors and extension lines or external cables can also be conveniently achieved through the junction box integrated into the photovoltaic tile 100. On one hand, when the photovoltaic tile 100 uses two junction boxes, a first junction box 150 and a second junction box 160, for the photovoltaic tile 100 located at the beginning of the array, the first positive terminal 152 on its first junction box 150 serves as the lead-out position of the first electrical connector 220, and the second positive terminal 154 on its first junction box 150 serves as the lead-out position of the third electrical connector 240. For the photovoltaic tile 100 located at the end of the array, the first negative terminal 162 on its second junction box 160 serves as the lead-out position of the second electrical connector 230, and the second negative terminal 164 on its second junction box 160 serves as the lead-out position of the fourth electrical connector 250.

[0128] On the other hand, when the photovoltaic tile 100 is configured with four junction boxes, for the photovoltaic tile 100 at the beginning of the array, the third junction box 170 provides the first electrical connector 220, and the fourth junction box 180 provides the third electrical connector 240. For the photovoltaic tile 100 at the end of the array, the fifth junction box 190 provides the second electrical connector 230, and the sixth junction box 194 provides the fourth electrical connector 250. This configuration ensures that each external connection point corresponds to an independent physical interface, greatly simplifying wiring operations and minimizing connection errors.

[0129] For example, such as Figure 9 As shown, the photovoltaic system 10 has three photovoltaic tile strings 200, namely the first photovoltaic tile string 200A, the second photovoltaic tile string 200B and the third photovoltaic tile string 200C. The first photovoltaic tile string 200A, the second photovoltaic tile string 200B and the third photovoltaic tile string 200C are arranged in parallel along the width direction of the system, and each photovoltaic tile string 200 contains three photovoltaic tiles 100.

[0130] The first positive terminal of the first photovoltaic tile in the first photovoltaic tile string 200A serves as the first electrical connector 220, and the second positive terminal of the first photovoltaic tile in the first photovoltaic tile string 200A serves as the third electrical connector 240. The first negative terminal of the third photovoltaic tile in the third photovoltaic tile string 200C serves as the second electrical connector 230, and the second negative terminal of the third photovoltaic tile in the third photovoltaic tile string 200C serves as the fourth electrical connector 250.

[0131] When the photovoltaic tile strings 200 are connected in series, the first negative terminal 134C of the third photovoltaic tile of the first photovoltaic tile string 200A is connected to the first positive terminal 132A of the first photovoltaic tile of the second photovoltaic tile string 200B, and the first negative terminal 134C of the third photovoltaic tile of the second photovoltaic tile string 200B is connected to the first positive terminal 132A of the first photovoltaic tile of the third photovoltaic tile string 300A.

[0132] Similarly, when the photovoltaic tile strings 200 are connected in series, the first negative terminal 144C of the third photovoltaic tile of the first photovoltaic tile string 200A is connected to the second positive terminal 142A of the first photovoltaic tile of the second photovoltaic tile string 200B, and the second negative terminal 144C of the third photovoltaic tile of the second photovoltaic tile string 200B is connected to the second positive terminal 142A of the first photovoltaic tile of the third photovoltaic tile string 300A.

[0133] This creates two completely independent current loops, ensuring that the current generated by the power generation units on both sides of the large curvature surface is transmitted through dedicated channels, fundamentally avoiding current mixing and power generation efficiency loss caused by the difference in light received on both sides of the curved surface.
