DETAILED DESCRIPTION

[0038] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0039] Unless otherwise specified, the up and down direction in this application refers to the vertical direction of the photovoltaic tile assembly, that is, the vertical direction; the left and right direction refers to the lateral direction of the photovoltaic tile assembly, that is, the horizontal direction.

[0040] Reference below Figure 1-Figure 6 A photovoltaic tile assembly and a rooftop photovoltaic system according to embodiments of the present application are described.

[0041] Solar energy utilization relies on photovoltaic tile assemblies to absorb solar energy. Photovoltaic tile assemblies are usually installed in arrays on the roof of a building to form a rooftop photovoltaic system. The roof of a building includes flat roofs, sloping roofs and special-shaped roofs. Multiple photovoltaic tile assemblies need to be able to be laid in the same plane so that the photovoltaic tile assemblies can be used in the construction of a photovoltaic roof.

[0042] like Figure 1 and Figure 2 As shown, the photovoltaic tile assembly of the embodiment of the present application includes: a first photovoltaic tile 11, a second photovoltaic tile 12 and a water retaining member 13, a portion of the first photovoltaic tile 11 is installed above the second photovoltaic tile 12, and the lower end frame 111 of the first photovoltaic tile 11 and a portion of the second photovoltaic tile 12 are vertically overlapped; the water retaining member 13 is installed on the lower end frame 111 of the first photovoltaic tile 11, and elastically stops at the upper surface of the second photovoltaic tile 12.

[0043] Part of the first photovoltaic tile 11 is installed above the second photovoltaic tile 12. This design can improve the utilization rate of the roof building 2 and increase the total power generation capacity of the photovoltaic tile assembly. The lower end frame 111 of the first photovoltaic tile 11 and a part of the second photovoltaic tile 12 are arranged to overlap vertically, which helps to improve the connection stability between the first photovoltaic tile 11 and the second photovoltaic tile 12 and reduce looseness or damage caused by wind or other external factors.

[0044] The lower end frame 111 of the first photovoltaic tile 11 and a part of the second photovoltaic tile 12 are arranged to overlap vertically, and there is an overlap gap between the lower end frame 111 of the first photovoltaic tile 11 and the second photovoltaic tile 12. The first photovoltaic tile 11 and the second photovoltaic tile 12 can be connected by overlapping, snapping or other detachable connection methods, and the detachable connection between the first photovoltaic tile 11 and the second photovoltaic tile 12 can facilitate replacement and maintenance; or the first photovoltaic tile 11 and the second photovoltaic tile 12 can be fixedly connected by means of flux or the like to increase the reliability of the photovoltaic tile assembly.

[0045] The first photovoltaic tile 11 includes a lower frame 111, an upper frame and a photovoltaic laminate with both ends clamped between the lower frame 111 and the upper frame, and the second photovoltaic tile 12 includes an upper frame 121, a lower frame and a photovoltaic laminate with both ends clamped between the upper frame 121 and the lower frame. The first photovoltaic tile 11 and the second photovoltaic tile 12 can be arranged in an array along the extension direction of the roof building 2. For example, when the roof building 2 is an inclined plane, the lower surface of the first photovoltaic component and the upper surface of the second photovoltaic component are vertically connected, and the multiple photovoltaic tile components are extended obliquely along the extension direction of the roof building 2 as a whole, wherein the first photovoltaic tile 11 and the second photovoltaic tile 12 can be placed horizontally or inclined horizontally.

[0046] Among them, photovoltaic laminates are usually laminated by photovoltaic cells, EVA (ethylene-vinyl acetate copolymer) films or glass, etc. The lamination technology allows these materials to be closely combined to form a whole to improve the voltage, current and efficiency of photovoltaic tiles.

[0047] The water retaining member 13 is installed on the lower end frame 111 of the first photovoltaic tile 11 located above, and part of the elasticity of the water retaining member 13 stops at the upper surface of the second photovoltaic tile 12 located below. The water retaining member 13 has a certain pressure and fit when in contact with the upper surface of the second photovoltaic tile 12. The water retaining member 13 can play a shielding role for the overlapping gap between the first photovoltaic tile 11 and the second photovoltaic tile 12. On the one hand, rainwater or other liquids can be effectively intercepted and guided by the water retaining member 13 when flowing through the surface of the photovoltaic tiles, thereby reducing the leakage of rainwater or other liquids through the gap between the first photovoltaic tile 11 and the second photovoltaic tile 12 to the roof building 2; on the other hand, it can compensate to a certain extent for the slight deformation between the first photovoltaic tile 11 and the second photovoltaic tile 12 caused by temperature changes or other factors.

[0048] The lower end or the lower middle part of the water retaining member 13 abuts against the upper surface of the second photovoltaic tile 12 located below, and the abutting part of the water retaining member 13 and the second photovoltaic tile 12 may be a rubber member or a plastic member.

[0049] According to the photovoltaic tile assembly provided in the embodiment of the present application, by vertically overlapping the lower end frame 111 of the first photovoltaic tile 11 and a part of the second photovoltaic tile 12, and installing the water retaining member 13 on the lower end frame 111 of the first photovoltaic tile 11 located above, and a part of the water retaining member 13 elastically stops against the upper surface of the second photovoltaic tile 12 located below, rainwater or other liquids can be effectively intercepted and guided by the water retaining member 13 when flowing through the surface of the photovoltaic tiles, thereby reducing the leakage of rainwater or other liquids through the gap between the first photovoltaic tile 11 and the second photovoltaic tile 12 to the roof building 2.

[0050] In some embodiments, Figure 2 As shown, the lower end of the water retaining member 13 elastically stops against the upper surface of the photovoltaic laminate of the second photovoltaic tile 12 .

[0051] Among them, the lower end of the water retaining member 13 elastically stops against the upper surface of the photovoltaic laminate of the second photovoltaic tile 12. Considering the good flatness of the upper surface of the photovoltaic laminate, the close fit between the water retaining member 13 and the photovoltaic laminate can improve the water retaining effect. Even when the external environment (such as temperature or wind force, etc.) changes and causes a slight displacement between the photovoltaic tiles, the water retaining member 13 can still maintain a good water retaining effect.

[0052] In some embodiments, Figure 2 As shown, the lower end frame 111 of the first photovoltaic tile 11 is provided with a mounting groove 112, and the mounting groove 112 is located above and spaced apart from the upper surface of the second photovoltaic tile 12, and the water retaining member 13 includes: a mounting portion 131 and a water retaining portion 132; the mounting portion 131 is installed in the mounting groove 112; the water retaining portion 132 is connected to the mounting portion 131, and the water retaining portion 132 elastically stops against the upper surface of the second photovoltaic tile 12.

[0053] A mounting groove 112 is provided on the lower end frame 111 of the first photovoltaic tile 11 . The mounting groove 112 is located above the upper surface of the second photovoltaic tile 12 and maintains a certain distance from the upper surface of the second photovoltaic tile 12 .

[0054] The mounting portion 131 of the water retaining member 13 is installed in the mounting groove 112, and the water retaining member 13 is snap-connected with the mounting groove 112. The water retaining member 13 has a size and shape that matches the mounting groove 112, so that the water retaining member 13 can be stably installed in the mounting groove 112. Compared with the adhesive connection method between the water retaining member 13 and the lower end frame 111 of the first photovoltaic tile 11, the water retaining member 13 is snap-connected in the mounting groove 112, which can not only realize the accurate and stable connection of the water retaining groove, but also facilitate the installation and replacement of the water retaining member 13, and is easy to use.

[0055] The water retaining portion 132 extends toward the upper surface of the second photovoltaic tile 12 and elastically stops at the upper surface of the second photovoltaic tile 12, so that the water retaining portion 132 can fit tightly against the upper surface of the second photovoltaic tile 12, and can adapt to certain deformation and displacement of the water retaining portion 132 and the second photovoltaic tile 12, thereby ensuring a long-term stable waterproof effect and effectively preventing rainwater or other liquids from passing through the water retaining portion 132 and flowing into the gap between the two tiles, thereby reducing the infiltration of rainwater or other liquids from the gap between the two tiles.

[0056] In some embodiments, Figure 2 As shown, the water retaining portion 132 extends obliquely from top to bottom in a direction away from the first photovoltaic tile 11 .

[0057] Among them, the water retaining portion 132 extends in an inclined shape along the direction from the mounting groove 112 to the upper surface of the second photovoltaic tile 12, and the inclined direction is toward the direction away from the first photovoltaic tile 11, that is, the water retaining surface of the water retaining portion 132 forms an obtuse angle with the second photovoltaic tile 12, and the water retaining surface of the water retaining portion 132 is the side away from the first photovoltaic tile 11.

[0058] Compared with the design that the water retaining part 132 extends obliquely toward the direction close to the first photovoltaic tile 11, since the water retaining part 132 is inclined in the direction away from the first photovoltaic tile 11, the distance between the position where the water retaining part 132 and the upper surface of the second photovoltaic tile 12 abut against each other and the gap between the two tiles can be increased. Even if rainwater or other liquid contacts the water retaining part 132, the water flow will be quickly guided to the direction away from the gap between the two tiles, thereby improving the water retaining performance of the water retaining part 132 and reducing the possibility of liquid infiltrating the gap of the photovoltaic tiles. At the same time, the inclined design of the water retaining part 132 can guide rainwater or other liquids to flow down along its surface, which helps to reduce the impact force of the water flow and reduce the situation where the accumulation of water flow causes leakage.

[0059] In some embodiments, Figure 3As shown, the water retaining member 13 further includes a connecting section 133 , through which the water retaining portion 132 is connected to the mounting portion 131 , the connecting section 133 passes through the notch 1121 of the mounting groove 112 , and the connecting section 133 extends vertically.

[0060] Among them, the connecting section 133 is used to connect the water retaining part 132 and the mounting part 131. The mounting part 131, the connecting section 133 and the water retaining part 132 can be connected by integral molding or the like. The connecting section 133 can extend the distance between the water retaining part 132 and the mounting part 131 while maintaining a certain elasticity to adapt to possible deformation and displacement.

[0061] The connecting section 133 passes through the slot 1121 of the mounting slot 112. When the water retaining member 13 is installed, the connecting section 133 will pass through the mounting slot 112 of the first photovoltaic tile 11, connecting the water retaining portion 132 and the mounting portion 131 together, so that the water retaining portion 132 can fit tightly on the upper surface of the second photovoltaic tile 12; and the connecting section 133 extends vertically, which can maintain the inclination angle and inclination length of the water retaining portion 132, so that it can effectively guide the water flow.

[0062] In some embodiments, the width of the connecting section 133 is smaller than the width of the mounting portion 131, so that the connecting section 133 can extend from the slot 1121 of the mounting slot 112 but the mounting portion 131 cannot extend out, thereby improving the connection stability between the mounting portion 131 and the mounting slot 112 and adapting to usage scenarios with different spacings between the first photovoltaic tile 11 and the second photovoltaic tile 12.

[0063] In some embodiments, Figure 4 As shown, the photovoltaic tile assembly also includes: a water stop 14, and at least part of the lower end frame 111 of the first photovoltaic tile 11 and the upper end frame 121 of the second photovoltaic tile 12 are vertically overlapped, and the water stop 14 is elastically clamped between the lower end frame 111 of the first photovoltaic tile 11 and the upper end frame 121 of the second photovoltaic tile 12.

[0064] The lower end frame 111 of the first photovoltaic tile 11 and the upper end frame 121 of the second photovoltaic tile 12 partially overlap in the vertical direction, and the water stop 14 is elastically clamped between the lower end frame 111 of the first photovoltaic tile 11 and the upper end frame 121 of the second photovoltaic tile 12. The water stop 14 forms a tight waterproof barrier to prevent rainwater or other liquids from seeping into the gap between the lower end frame 111 of the first photovoltaic tile 11 and the upper end frame 121 of the second photovoltaic tile 12.

[0065] Among them, the water stop member 14 is clamped between the lower end frame 111 of the first photovoltaic tile 11 and the upper end frame 121 of the second photovoltaic tile 12, which can improve the sealing performance of the gap between the first photovoltaic tile 11 and the second photovoltaic tile 12 and reduce the possibility of liquid penetrating into the gap of the photovoltaic tiles.

[0066] Exemplarily, the water stop 14 may be a sealing strip or a plastic gasket. The water stop 14 is elastic and can be tightly clamped between the lower frame 111 of the first photovoltaic tile 11 and the upper frame 121 of the second photovoltaic tile 12, thereby reducing the gap between the lower frame 111 of the first photovoltaic tile 11 and the upper frame 121 of the second photovoltaic tile 12, and can adapt to slight deformation caused by factors such as temperature and wind.

[0067] In some embodiments, Figure 5 As shown, the upper surface of the water stop member 14 is provided with a plurality of spaced-apart tooth-shaped structures 141 , and the tooth-shaped structures 141 abut against the lower surface of the lower end frame 111 of the first photovoltaic tile 11 .

[0068] In this embodiment, the tooth-shaped structure 141 can be distributed in an array along the extension direction of the upper surface of the water stop 14. The tooth-shaped structure 141 abuts against the lower surface of the lower end frame 111 of the first photovoltaic tile 11. The tooth-shaped structure 141 can reduce the stiffness of the upper surface of the water stop 14. When the water stop 14 is elastically clamped between the lower end frame 111 of the first photovoltaic tile 11 and the upper end frame 121 of the second photovoltaic tile 12, the tooth-shaped structure 141 can increase the deformation ability of the water stop 14, thereby increasing the deformation degree of the water stop 14, reducing the gap width between the water stop 14 and the lower end frame 111 of the first photovoltaic tile 11, and further reducing the possibility of liquid penetrating into the gaps of the photovoltaic tiles.

[0069] The tooth width and tooth depth of the plurality of tooth-shaped structures 141 may be of the same structure or of different structures, and may be specifically determined according to the thickness of the water stop member 14 and the area of ​​the upper surface of the water stop member 14 .

[0070] In some embodiments, Figure 4 and Figure 5 As shown, the upper surface of the upper end frame 121 of the second photovoltaic tile 12 includes a first supporting surface and a second supporting surface, the second supporting surface is located on the side of the first supporting surface close to the lower end frame of the second photovoltaic tile 12, and the first supporting surface is lower than the second supporting surface; the lower surface of the water stop 14 includes a first surface 143 and a second surface 144, the first surface 143 is lower than the second surface 144, the first surface 143 abuts the first supporting surface, and the second surface 144 abuts the second supporting surface.

[0071] Among them, the upper surface of the upper end frame 121 of the second photovoltaic tile 12 is stepped, and the lower surface of the water stop 14 is stepped to match the upper surface of the upper end frame 121 of the second photovoltaic tile 12, which can increase the contact area between the upper surface of the upper end frame 121 of the second photovoltaic tile 12 and the lower surface of the water stop 14, so as to achieve a better fitting effect between the lower surface of the water stop 14 and the upper surface of the upper end frame 121 of the second photovoltaic tile 12.

[0072] The first surface 143 abuts against the first supporting surface, and the second surface 144 abuts against the second supporting surface. When the water stop 14 is under pressure, the structure can bear the force evenly, thereby preventing the water stop 14 from being damaged due to excessive local stress.

[0073] In this embodiment, the water stop 14 can form a tight waterproof barrier between the lower frame 111 of the first photovoltaic tile 11 and the upper frame 121 of the second photovoltaic tile 12. The toothed structure 141, the stepped shape of the upper surface of the upper frame 121 of the second photovoltaic tile 12, and the stepped design of the lower surface of the water stop 14 jointly improve the waterproof performance and stability of the gap between the first photovoltaic tile 11 and the second photovoltaic tile 12, providing a strong guarantee for the long-term stable operation of the photovoltaic system.

[0074] In some embodiments, Figure 4 and Figure 5 As shown, the end of the water stop 14 away from the lower end frame of the second photovoltaic tile 12 is provided with a flange 142, and the flange 142 abuts against the end surface of the upper end frame 121 of the second photovoltaic tile 12 away from the lower end frame of the second photovoltaic tile 12.

[0075] The flange 142 is disposed at one end of the water stop 14 away from the lower frame 111 of the first photovoltaic tile 11, and is located at one end away from the lower frame 111 of the second photovoltaic tile 12. The design of the flange 142 can increase the contact area between the water stop 14 and the lower frame 111 of the second photovoltaic tile 12, and the flange 142 can enhance the stability of the connection between the water stop 14 and the lower frame 111 of the second photovoltaic tile 12, reduce the infiltration of water from the edge, and further improve the waterproof performance.

[0076] In some embodiments, Figure 6 As shown, the photovoltaic tile assembly also includes: a support 15, the support 15 includes: a first card slot 151, a second card slot 152 and a connecting structure 153 for connecting to the roof building 2; at least a portion of the lower end frame 111 of the first photovoltaic tile 11 is located in the first card slot 151, and the slot wall of the first card slot 151 has a first card member 1511 that is engaged with the lower end frame 111 of the first photovoltaic tile 11; at least a portion of the upper end frame 121 of the second photovoltaic tile 12 is located in the second card slot 152, and the slot wall of the second card slot 152 has a second card member 1521 that is engaged with the upper end frame 121 of the second photovoltaic tile 12; the connecting structure 153 is connected to the first card slot 151 and the second card slot 152.

[0077] Among them, the first photovoltaic tile 11 and the second photovoltaic tile 12 are connected to the roof building 2 through a support 15, and the support 15 is used to fix the first photovoltaic tile 11 and the second photovoltaic tile 12. The support 15 can be connected to the roof building 2 by screws, bolts, clamps, welding or other fixing devices.

[0078] The support 15 includes two first slots 151 and a second slot 152, and the first slot 151 and the second slot 152 are respectively used to fix two adjacent photovoltaic tiles in the photovoltaic tile assembly. The first slot 151 and the second slot 152 have the same notch orientation, so that the first slot 151 is assembled with the first photovoltaic tile 11, and the second slot 152 is assembled with the second photovoltaic tile 12.

[0079] The bottom or frame part of the lower end frame 111 of the first photovoltaic tile 11 is located in the first card slot 151, and the groove wall of the first card slot 151 is designed with a first clamping member 1511. The first clamping member 1511 matches the lower end frame 111 of the first photovoltaic tile 11 and is tightly clamped, thereby improving the stability of the connection between the first photovoltaic tile 11 and the support 15.

[0080] At least a portion of the upper frame 121 of the second photovoltaic tile 12 is located in the second slot 152. The slot wall of the second slot 152 is also designed with a second clamp 1521, which matches and is tightly clamped with the upper frame 121 of the second photovoltaic tile 12, thereby improving the stability of the connection between the second photovoltaic tile 12 and the support 15.

[0081] The connection structure 153 may be a protruding plate-like structure. The connection structure 153 extends along the extension direction of the roof building 2 . The connection structure 153 may be fastened to the roof building 2 by bolts.

[0082] In this embodiment, through this structural design, the photovoltaic tile assembly can be conveniently installed on the roof building 2, and due to the design of the slot and the clamp, the connection between the photovoltaic tile and the support 15 is also more stable and reliable. In addition, this structure can quickly fix the photovoltaic tile on the support 15 through the slot and the clamp without using complicated fixing tools or methods, thereby improving the installation efficiency of the photovoltaic tile assembly.

[0083] In some embodiments, Figure 1 As shown, the first photovoltaic tile 11 and the second photovoltaic tile 12 adjacent to each other in the transverse direction are overlapped end to end.

[0084] The first photovoltaic tile 11 and the second photovoltaic tile 12 adjacent to each other in the transverse direction are overlapped end to end. This overlap can form a continuous waterproof barrier between the photovoltaic tiles in the transverse direction to prevent moisture from penetrating through the gaps.

[0085] Exemplarily, the first photovoltaic tile 11 and the second photovoltaic tile 12 can be arranged horizontally, with the first photovoltaic tile 11 located above the second photovoltaic tile 12, that is, the tail end of the first photovoltaic tile 11 is overlapped with the head end of the second photovoltaic tile 12, and the height of the photovoltaic tile array in the horizontal direction extends in a step-down manner to adapt to the sloping roof building 2.

[0086] Exemplarily, the first photovoltaic tile 11 and the second photovoltaic tile 12 can be arranged at an inclination along the direction of the sloping roof building 2, that is, the tail end of the first photovoltaic tile 11 is overlapped on the head end of the second photovoltaic tile 12, and the height of the photovoltaic tile array in the transverse direction extends in a decreasing trend to adapt to the sloping roof building 2.

[0087] In this embodiment, the length and angle of the overlap between the first photovoltaic tile 11 and the second photovoltaic tile 12 can be adjusted according to the application scenario and design requirements of the specific roof building 2 to achieve the best waterproof effect and stability.

[0088] An embodiment of the present application also provides a rooftop photovoltaic system, comprising a photovoltaic tile assembly as in any of the above embodiments.

[0089] According to the rooftop photovoltaic system provided by the embodiments of the present application, by setting up a photovoltaic tile assembly of any of the above embodiments, the photovoltaic tile assembly is arranged by vertically overlapping the lower end frame 111 of the first photovoltaic tile 11 and a part of the second photovoltaic tile 12, and the water retaining member 13 is installed on the lower end frame 111 of the first photovoltaic tile 11 located above, and a part of the water retaining member 13 elastically stops against the upper surface of the second photovoltaic tile 12 located below, so that rainwater or other liquids can be effectively intercepted and guided by the water retaining member 13 when flowing through the surface of the photovoltaic tiles, thereby reducing the leakage of rainwater or other liquids through the gap between the first photovoltaic tile 11 and the second photovoltaic tile 12 to the roof building 2.
