[0012] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0013] Please refer to Figure 1 The present application provides a photovoltaic colored tile roof system 1 with good waterproof performance.

[0014] The photovoltaic glazed tile roof system 1 comprises a support 10 and a photovoltaic assembly 20. The support 10 is used to be installed on a building roof 2. The photovoltaic assembly 20 comprises a plurality of tile rows 21 and a plurality of hip tile rows 22 which are alternately arranged along a first preset direction MM' and are installed on the support 10, the tile rows 21 are curved away from the support 10 to be arched with a middle high and two sides low, the hip tile rows 22 are curved toward the support 10 to be arched with a middle low and two sides high, the side edges of the tile rows 21 are attached to the sides of the hip tile rows 22 which are away from the support 10, and the rise-span ratio of the tile rows 21 is greater than that of the hip tile rows 22.

[0015] The specific structure of the photovoltaic glazed tile roof system 1 will be introduced below; it should be noted that the application scenarios of the photovoltaic glazed tile roof system 1 are not limited here, and the photovoltaic glazed tile roof system 1 can be but is not limited to being applied to traditional official ancient buildings such as historical protected buildings. Figures 1-4 The specific structure of the photovoltaic glazed tile roof system 1 will be introduced below; it should be noted that the application scenarios of the photovoltaic glazed tile roof system 1 are not limited here, and the photovoltaic glazed tile roof system 1 can be but is not limited to being applied to traditional official ancient buildings such as historical protected buildings.

[0016] As shown in Figure 1 The photovoltaic glazed tile roof system 1 comprises a support 10 and a photovoltaic assembly 20.

[0017] The support 10 is used to provide support for the photovoltaic assembly 20, and the specific structure of the support 10 will be introduced below.

[0018] The support 10 is used to be installed on a building roof 2. The specific installation mode between the support 10 and the building roof 2 is not limited here, and the designer can reasonably design according to actual needs; for example, the support 10 can be but is not limited to being installed on the building roof 2 by screwing.

[0019] The photovoltaic assembly 20 is used to convert solar energy into electrical energy, and the photovoltaic assembly 20 comprises a plurality of tile rows 21 and a plurality of hip tile rows 22.

[0020] The plurality of tile rows 21 and the plurality of hip tile rows 22 are installed on the support 10. The specific installation mode between the tile rows 21 (the hip tile rows 22) and the support 10 is not limited here, and the designer can reasonably design according to actual needs; for example, the tile rows 21 (the hip tile rows 22) can be but are not limited to being detachably connected with the support 10 by at least one of screwing, clamping or inserting; for another example, the tile rows 21 (the hip tile rows 22) can also be but are not limited to being non-detachably connected with the support 10 by riveting.

[0021] The plurality of tile columns 21 and the plurality of hip columns 22 are arranged alternately along the first preset direction MM', that is, along the first preset direction MM', the plurality of tile columns 21 and the plurality of hip columns 22 are arranged in the order of tile column 21, hip column 22, tile column 21, hip column 22, tile column 21, hip column 22, tile column 21, and so on.

[0022] The tile columns 21 are curved to be arched with the middle high and the two sides low in the direction away from the support 10, and the hip columns 22 are curved to be arched with the middle low and the two sides high in the direction toward the support 10, that is, the curved direction of the tile columns 21 is opposite to the curved direction of the hip columns 22.

[0023] The side edges of the tile columns 21 are attached to the side of the hip columns 22 away from the support 10, so as to effectively reduce the gap between the tile columns 21 and the hip columns 22, and play a waterproof role.

[0024] The rise-span ratio of the tile columns 21 is greater than the rise-span ratio of the hip columns 22, so that the tile columns 21 curved in the direction away from the support 10 are arched to a greater extent than the hip columns 22 curved in the direction toward the support 10, and the rainwater falling on the tile columns 21 will flow along the outer surface of the tile columns 21 to the hip columns 22, and then flow along the outer surface of the hip columns 22 downward, and the rainwater falling directly on the hip columns 22 will flow along the outer surface of the hip columns 22 downward. It should be noted that the greater the rise-span ratio of the tile columns 21, the steeper the geometric arc cross section of the tile columns 21, and the smaller the rise-span ratio of the hip columns 22, the flatter the geometric arc cross section of the hip columns 22.

[0025] It should be noted that by designing the hip columns 22 to be arched in the direction toward the support 10, the rainwater falling on the hip columns 22 will flow along the outer surface of the hip columns 22 to the middle of the hip columns 22, and then flow along the outer surface of the hip columns 22 downward, so as to reduce or even avoid the rainwater flowing from the joint between the tile columns 21 and the hip columns 22 into the inside of the tile columns 21 and the hip columns 22, and improve the waterproof performance of the photovoltaic glazed tile roof system 1.

[0026] Based on the photovoltaic glazed tile roof system 1 in the embodiment of the present application, by arranging the plurality of tile rows 21 curved away from the support 10 and the plurality of hip tile rows 22 curved toward the support 10 in the first preset direction MM' on the support 10 to form a continuous concave-convex structure, and by making the side edges of the tile rows 21 fit with the side of the hip tile rows 22 away from the support 10, the tile rows 21 can not only cover the interval between the adjacent two hip tile rows 22, but also effectively reduce the gap between the tile rows 21 and the hip tile rows 22, so that the photovoltaic glazed tile roof system 1 has good waterproof effect. By designing the rise-span ratio of the tile rows 21 to be greater than the rise-span ratio of the hip tile rows 22, the arching degree of the tile rows 21 curved away from the support 10 is greater than the arching degree of the hip tile rows 22 curved toward the support 10. In this way, the rainwater falling on the tile rows 21 flows along the outer surface of the tile rows 21 to the hip tile rows 22, and the rainwater falling on the hip tile rows 22 flows along the outer surface of the hip tile rows 22 to the middle part of the hip tile rows 22 and then flows downward along the outer surface of the hip tile rows 22. Since the rise-span ratio of the hip tile rows 22 is small, the geometric arc cross section of the hip tile rows 22 is relatively flat, and the rainwater cannot accumulate on the hip tile rows 22, so that the photovoltaic glazed tile roof system 1 has good waterproof performance.

[0027] As shown in Figure 1 Each tile row 21 includes a plurality of tile monomers 211 mounted on the support 10, each tile monomer 211 is curved away from the support 10 to form an arch shape with high in the middle and low on both sides, and the plurality of tile monomers 211 are arranged along the second preset direction NN'. The tail end of the tile monomer 211 at the high position covers the head end of the tile monomer 211 at the low position. Each hip tile row 22 includes a plurality of hip tile monomers 221 mounted on the support 10, each hip tile monomer 221 is curved toward the support 10 to form an arch shape with low in the middle and high on both sides, and the plurality of hip tile monomers 221 are arranged along the second preset direction NN'. The tail end of the hip tile monomer 221 at the high position covers the head end of the hip tile monomer 221 at the low position.

[0028] Among them, the tile monomer 211 is a unit of the tile row 21, and the plurality of tile monomers 211 are arranged along the second preset direction NN' to stack to form the tile row 21. The specific structure of the tile monomer 211 will be described below. The specific connection mode between the tile monomer 211 and the support 10 is not limited here, and the designer can reasonably design according to actual needs; for example, the tile monomer 211 can be but not limited to detachably connected with the support 10 by at least one of the modes such as screwing, clamping or inserting; for another example, the tile monomer 211 can also be but not limited to non-detachably connected with the support 10 by riveting.

[0029] The tile body 221 is a unit of the tile column 22, and a plurality of tile bodies 221 are arranged along the second preset direction NN' to stack to form the tile column 22. The specific structure of the tile body 221 will be described below. The specific connection mode between the tile body 221 and the support 10 is not limited here, and the designer can reasonably design according to actual needs; for example, the tile body 221 can be, but is not limited to, detachably connected with the support 10 by at least one of screwing, clamping or inserting; for another example, the tile body 221 can also be, but is not limited to, non-detachably connected with the support 10 by riveting.

[0030] The second preset direction NN' intersects the first preset direction MM', that is, the second preset direction NN' at least includes a component perpendicular to the first preset direction MM'; for example, the second preset direction NN' perpendicularly intersects the first preset direction MM'.

[0031] By designing a plurality of tile bodies 211, and allowing the tail end cover of the tile body 211 at the high position in the tile column 21 to cover the head end of the adjacent tile body 211 at the low position, on the one hand, it is convenient for the installer to install the tile bodies 211 from low to high, and on the other hand, rainwater cannot accumulate at the connection between the adjacent two tile bodies 211 (that is, the tail end of the tile body 211 at the high position and the head end of the tile body 211 at the low position), so as to improve the waterproof performance of the photovoltaic glazed tile roof system 1. By designing a plurality of tile bodies 221, and allowing the tail end cover of the tile body 221 at the high position in the tile column 22 to cover the head end of the adjacent tile body 221 at the low position, on the one hand, it is convenient for the installer to install the tile bodies 221 from low to high, and on the other hand, rainwater cannot accumulate at the connection between the adjacent two tile bodies 221 (that is, the tail end of the tile body 221 at the high position and the head end of the tile body 221 at the low position), so as to improve the waterproof performance of the photovoltaic glazed tile roof system 1.

[0032] As Figure 1As shown, for the adjacent tile column 21 and the hip tile column 22, the joint gap between the adjacent two tile monomers 211 in the tile column 21 is staggered with the joint gap between the adjacent two hip tile monomers 221 in the hip tile column 22, and the side edge of the tile monomer 211 is attached to the side of the hip tile monomer 221 away from the support 10. Compared with aligning the joint gap between the adjacent two tile monomers 211 in the tile column 21 with the joint gap between the adjacent two hip tile monomers 221 in the hip tile column 22, this can effectively prevent rainwater from flowing into the inside of the tile monomer 211 and the hip tile monomer 221 from the joint gap between the two, and can improve the waterproof performance of the photovoltaic glazed tile roof system 1. By attaching the side edge of the tile monomer 211 to the side of the hip tile monomer 221 away from the support 10, the gap between the tile monomer 211 and the hip tile monomer 221 can be effectively reduced, thereby achieving the waterproof effect. It is worth mentioning that, in the present application, the ratio of the height to the span of the tile monomer 211 is designed to be greater than the ratio of the height to the span of the hip tile monomer 221, the positions of the tile monomers 211 and the hip tile monomers 221 in the adjacent tile column 21 and the hip tile column 22 are reasonably arranged, the joint gap between the two tile monomers 211 is staggered with the joint gap between the adjacent two hip tile monomers 221, and the side edge of the tile monomer 211 is attached to the side of the hip tile monomer 221 away from the support 10. In this way, through the cooperation of the structure and the position of the tile monomer 211 and the hip tile monomer 221, the photovoltaic glazed tile roof system 1 has good waterproof performance. Compared with directly using glue to bond and fix the tile monomer 211 and the hip tile monomer 221 (i.e., the glue completely blocks the gap between the tile monomer 211 and the hip tile monomer 221), the photovoltaic glazed tile roof system 1 also has good heat dissipation performance, which can timely dissipate the heat generated in the working process of the hip tile monomer 221.

[0033] The ratio of the height to the span of the tile monomer 211 is greater than or equal to 0.3 and less than or equal to 0.5. For example, the ratio of the height to the span of the tile monomer 211 can be, but is not limited to, 0.3, 0.35, 0.4, 0.45 or 0.5, etc. By reasonably designing the ratio of the height to the span of the tile monomer 211, the structural strength of the tile monomer 211 can be ensured, and at the same time, the rainwater falling on the tile monomer 211 can flow along the outer surface of the tile monomer 211 to the hip tile monomer 221, then flow along the outer surface of the hip tile monomer 221 to the middle of the hip tile monomer 221, and then flow downward along the outer surface of the hip tile monomer 221.

[0034] The rise-to-span ratio of the roof tile 221 is greater than or equal to 0.05 and less than or equal to 0.08. For example, the rise-to-span ratio of the roof tile 221 can be, but is not limited to, 0.05, 0.055, 0.06, 0.065, 0.07, 0.075, or 0.08. By rationally designing the rise-to-span ratio of the roof tile 221, while ensuring the structural strength of the roof tile 221, rainwater falling on the roof tile 221 can be allowed to flow down the outer surface of the roof tile 221 towards the center of the roof tile 221, and then flow down the outer surface of the roof tile 221. With a reasonable rise-to-span ratio design, rainwater will not accumulate on the roof tile 221. It should be noted that the smaller the sag-span ratio of the inverted solar cell 221, the higher the photovoltaic conversion efficiency. Furthermore, the flatter the geometric arc cross-section of the inverted solar cell 221, the lower the process requirements for the cell layer 221c (described below) of the inverted solar cell 221 (for example, the larger the sag-span ratio of the inverted solar cell 221, the greater the possibility of microcracks in the cell layer 221c). This results in a higher yield and lower cost.

[0035] like Figure 1 As shown, the support 10 includes multiple horizontal beams 11 and multiple inclined beams 12; the multiple horizontal beams 11 are arranged at intervals along a second preset direction NN', and each horizontal beam 11 extends along a first preset direction MM', the roof tile 221 rests against the horizontal beams 11 and is connected to the horizontal beams 11; the multiple inclined beams 12 are located on the side of the horizontal beams 11 away from the building roof 2, the multiple inclined beams 12 are arranged at intervals along the first preset direction MM', and each inclined beam 12 extends along the second preset direction NN', the inclined beams 12 are connected to the horizontal beams 11 and the spacing between adjacent inclined beams 12 is adjustable, the roof tile 211 corresponds to the inclined beams 12 and is connected to the inclined beams 12.

[0036] The crossbeam 11 is installed on the building roof 2. The specific installation method between the crossbeam 11 and the building roof 2 is not limited here. Designers can make reasonable designs according to actual needs. For example, the crossbeam 11 can be fixedly connected to the building roof 2 by means of screws, but not limited to screws.

[0037] The inverted tile unit 221 is supported by and connected to the crossbeam 11; the specific connection method between the inverted tile unit 221 and the crossbeam 11 is not limited here, and the designer can make a reasonable design according to the actual needs; for example, the inverted tile unit 221 can be detachably connected to the crossbeam 11 by at least one of the following methods: screw connection, snap connection or plug connection; or, for example, the inverted tile unit 221 can also be non-detachably connected to the crossbeam 11 by riveting.

[0038] The inclined beam 12 is connected to the horizontal beam 11, and the spacing between adjacent inclined beams 12 is adjustable. The specific connection method between the inclined beam 12 and the horizontal beam 11 is not limited here; designers can design it reasonably according to actual needs. For example, the inclined beam 12 can be slidably connected to the horizontal beam 11 by a slider (set on one of the inclined beam 12 and the horizontal beam 11) and a groove (set on the other of the inclined beam 12 and the horizontal beam 11), so that the spacing between adjacent inclined beams 12 is adjustable. After the spacing between adjacent inclined beams 12 is adjusted, the inclined beam 12 can be positioned on the horizontal beam 11 by screws, but not limited to this method. It is understood that the width of the roof tile unit 221 in the first preset direction MM' varies for different building roofs 2. By designing the spacing between adjacent inclined beams 12 to be adjustable, the bracket 10 can be installed with roof tile units 221 of different widths, improving the applicability of the photovoltaic glazed tile roofing system 1.

[0039] The barrel tile unit 211 corresponds to and is connected to the inclined beam 12; the specific connection method between the barrel tile unit 211 and the inclined beam 12 is not limited here, and the designer can make a reasonable design according to the actual needs; for example, the barrel tile unit 211 can be detachably connected to the inclined beam 12 by at least one of the following methods: screw connection, snap connection or plug connection; or, for example, the barrel tile unit 211 can also be non-detachably connected to the inclined beam 12 by riveting.

[0040] like Figure 2 and Figure 3 As shown, the barrel tile unit 211 includes a main body 211a and a connecting part 211b. The main body 211a is bent away from the support 10 to form an arch shape that is higher in the middle and lower on both sides. The connecting part 211b is bent and connected to one end of the main body 211a as the first end of the barrel tile unit 211. The connecting part 211b is provided with a first fixing hole 211c. The photovoltaic glazed tile roofing system 1 also includes a first fastener 30. The first fastener 30 passes through the first fixing hole 211c and is connected to the inclined beam 12 to position the barrel tile unit 211 on the inclined beam 12.

[0041] The main body 211a and the connecting part 211b are integrally formed.

[0042] The first fastener 30 is a component cooperating with the first fixing hole 211c to realize the relative position fixation between the tile body 211 and the inclined beam 12. The specific form of the first fastener 30 cooperating with the first fixing hole 211c is different according to the specific form of the first fixing hole 211c; for example, when the first fixing hole 211c is a threaded hole on the inclined beam 12, the first fastener 30 includes a screw, and at this time, the tile body 211 realizes the relative position fixation with the inclined beam 12 by the way of locking the screw; for another example, when the first fixing hole 211c is a clamping hole on the inclined beam 12, the first fastener 30 includes a clamping pin, and at this time, the tile body 211 realizes the relative position fixation with the inclined beam 12 by the way of clamping the clamping pin; for another example, when the first fixing hole 211c is a plug hole on the inclined beam 12, the first fastener 30 includes a plug pin, and at this time, the tile body 211 realizes the relative position fixation with the inclined beam 12 by the way of plugging the plug pin.

[0043] By designing the first fastener 30, the first fastener 30 is arranged through the first fixing hole 211c and connected with the inclined beam 12 to realize the relative position fixation between the tile body 211 and the inclined beam 12, which is simple in structure and easy to realize.

[0044] As shown in FIGS. 1, 2 and 3, the first end of the tile body 211 is provided with a first fixing hole 211c. The photovoltaic glazed tile roof system 1 further includes a first fastener 30, the first fastener 30 is arranged through the first fixing hole 211c and connected with the inclined beam 12 to fix the tile body 211 on the inclined beam 12. Figure 2 Figure 4 As shown in FIGS. 1, 2 and 3, the first end of the tile body 211 is provided with a first fixing hole 211c. The photovoltaic glazed tile roof system 1 further includes a first fastener 30, the first fastener 30 is arranged through the first fixing hole 211c and connected with the inclined beam 12 to fix the tile body 211 on the inclined beam 12.

[0045] The second fastener 40 is a component cooperating with the second fixing hole 221f to realize the relative position fixation between the tile body 221 and the inclined beam 12. The specific form of the second fastener 40 cooperating with the second fixing hole 221f is different according to the specific form of the second fixing hole 221f; for example, when the second fixing hole 221f is a threaded hole on the inclined beam 12, the second fastener 40 includes a screw, and at this time, the tile body 221 realizes the relative position fixation with the inclined beam 12 by the way of locking the screw; for another example, when the second fixing hole 221f is a clamping hole on the inclined beam 12, the second fastener 40 includes a clamping pin, and at this time, the tile body 221 realizes the relative position fixation with the inclined beam 12 by the way of clamping the clamping pin; for another example, when the second fixing hole 221f is a plug hole on the inclined beam 12, the second fastener 40 includes a plug pin, and at this time, the tile body 221 realizes the relative position fixation with the inclined beam 12 by the way of plugging the plug pin.

[0046] By designing the second fastener 40, the second fastener 40 is arranged through the second fixing hole 221f and connected with the inclined beam 12 to realize the relative position fixation between the tile body 221 and the inclined beam 12, which is simple in structure and easy to realize.​

[0047] As shown in Figure 4 Each of the roof tile monomers 221 comprises a glass backboard 221a, a first adhesive film layer 221b, a battery piece layer 221c, a second adhesive film layer 221d, and a glass panel 221e which are sequentially stacked, and the glass backboard 221a is closer to the support 10 than the glass panel 221e.

[0048] The glass backboard 221a serves as the bottom plate of the roof tile monomer 221 and provides support for structures such as the battery piece layer 221c, the glass panel 221e, and the like of the roof tile monomer 221. It should be noted that the glass panel 221e can be colored by printing as needed to form a glazed photovoltaic tile, making the photovoltaic glazed tile roof system 1 look more aesthetically pleasing.

[0049] The first adhesive film layer 221b serves as one of the adhesive members of the roof tile monomer 221 and is used to adhere and fix the battery piece layer 221c to the glass backboard 221a. The specific material of the first adhesive film layer 221b is not limited here, and the designer can make a reasonable choice as needed. For example, the first adhesive film layer 221b can include, but is not limited to, at least one of a POE (Polyolefin elastomer) adhesive layer, an EVA (Ethylene-vinyl acetate copolymer) adhesive layer, a PVB (Polyvinl butaral) adhesive layer, a polyurethane adhesive layer, and an epoxy resin adhesive layer. In this way, the glass panel 221e and the battery piece layer 221c are firmly adhered through the first adhesive film layer 221b. It should be noted that the number of first adhesive film layers 221b can be one or more (two or more), and in the embodiment of the present application, the number of first adhesive film layers 221b is two.

[0050] The battery piece layer 221c serves as a structural member of the roof tile monomer 221 for converting solar energy into electrical energy, and the battery piece layer 221c is flexible. It should be noted that the roof tile monomer 221 is curved towards the support 10, and by designing the battery piece layer 221c to be flexible, the bending radius of the roof tile monomer 221 can be adapted, which can reduce the possibility of hidden cracks in the battery piece layer 221c and ensure that the roof tile monomer 221 can convert solar energy into electrical energy.

[0051] The second adhesive layer 221d serves as another adhesive component for the roof cell 221, used to bond and fix the glass panel 221e to the battery cell layer 221c. The specific material of the second adhesive layer 221d is not limited; designers can choose according to actual needs. For example, the second adhesive layer 221d can include, but is not limited to, at least one of POE (Polyolefin elastomer), EVA (Ethylene-vinyl acetate copolymer), PVB (Polyvinyl butaral), polyurethane, and epoxy resin. This ensures a strong bond between the battery cell layer 221c and the glass backsheet 221a through the second adhesive layer 221d. It should be noted that the number of second adhesive layers 221d can be one or more (two or more); in this embodiment, the number of second adhesive layers 221d is one.

[0052] The glass panel 221e serves as a cover for the inverted solar cell 221, preventing the solar cell layer 221c from directly contacting the outside world and providing buffer protection for the solar cell layer 221c.

[0053] Furthermore, such as Figure 4 As shown, each roof tile 221 also includes a welding strip 221g, which is located between the first adhesive film layer 221b and the second adhesive film layer 221d. The welding strip 221g is distributed on both sides of the battery cell layer 221c along the second preset direction NN', and is electrically connected to the battery cell layer 221c. The welding strip 221g is similar to an electrical connector such as a wire, and is used to electrically connect to the cable 3. A gap is formed between the inner side of the roof tile 211 and the inclined beam 12, and the cable 3 can be buried in this gap for easy wiring. At the same time, the roof tile 211 covers the cable 3, which can effectively reduce the possibility of damage to the cable 3 and also serves a waterproof function. It is worth mentioning that the gap formed between the inner side of the roof tile 211 and the inclined beam 12 is conducive to forming a heat dissipation channel to a certain extent, which can dissipate the heat generated by the cable 3 during operation in a timely manner.

[0054] Considering that the span ratio of the cylindrical tile unit 211 is relatively large, and according to the trajectory of the sun rising in the east and setting in the west, the light-receiving surface of the cylindrical tile unit 211 is relatively small. Therefore, the cylindrical tile unit 211 is structurally different from the inverted tile unit 221 in that the cylindrical tile unit 211 does not include the aforementioned battery cell layer 221c. In other words, the cylindrical tile unit 211 does not need to convert solar energy into electrical energy.

[0055] like Figure 1As shown, it can be understood that in heavy rain or heavy rain weather, rainwater will inevitably penetrate into the inner side of the tile body 211 and the tile body 221, in order to avoid rainwater penetration into the building roof 2, therefore the photovoltaic glazed tile roof system 1 is designed to further include a waterproof layer 50, the waterproof layer 50 is arranged on the side of the bracket 10 facing the building roof 2. Among them, the waterproof layer 50 can include but not limited to an asphalt layer or a polyethylene film layer. It is worth mentioning that the cooperation of the tile body 211 and the tile body 221 in structure and position makes the photovoltaic glazed tile roof system 1 have a double waterproof performance, and the cooperation of the waterproof layer 50 makes the photovoltaic glazed tile roof system 1 have a double waterproof performance.
