It should be noted that the terms "first," "second," and the like in the description and in the claims are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.

An aspect of the present utility model provides a stacked assembly structure of photovoltaic tiles, as shown in fig. 1 to 3, where an alternative embodiment includes a plurality of photovoltaic tiles 1 that are arched up in a single curved manner, and the plurality of photovoltaic tiles 1 may be placed in a manner that they are partially stacked in sequence along their length direction; and, spacing can be carried out through the limit structure in middle part and/or lateral part between the adjacent photovoltaic tile 1.

It can be understood that, compared with the photovoltaic tile 1 with the wavy multi-curved structure in the related art, the photovoltaic tile 1 can reduce the processing difficulty of the photovoltaic tile 1, improve the yield of the lamination processing of the photovoltaic tile 1, and further reduce the production cost of the photovoltaic tile 1. Moreover, due to the single curved arch structure of the photovoltaic tiles 1, when the adjacent photovoltaic tiles 1 are assembled, the arch structure of the previous photovoltaic tile 1 can position the assembly and the paving of the next photovoltaic tile 1, so that the assembly of the photovoltaic tiles 1 can be conveniently and rapidly realized. Meanwhile, on the basis that the photovoltaic tiles 1 of the single-curved arch structure have a certain limiting function, the adjacent photovoltaic tiles 1 are matched through the limiting structure, so that the stability of the assembly structure of the photovoltaic tiles can be further improved.

In this embodiment, as shown in fig. 4 to 7, the photovoltaic tile 1 includes an upper glass 11, an upper film 12, a battery piece 13, a lower film 14 and a lower glass 15 from top to bottom, and the photovoltaic tile 1 further includes a pair of frames 19. The upper glass 11, the upper film 1, the battery piece 13, the lower film 14 and the lower glass 15 are all of a single curved structure which is arched upwards, and the curvatures of the upper glass 11, the upper film 1, the battery piece 13, the lower film 14 and the lower glass 15 are consistent. The upper glass 11 and the lower glass 15 have light transmittance, and the upper glass 11 and the lower glass 15 can protect the battery cells 13 mounted therebetween. A pair of rims 19 may clamp both sides of the upper glass 11 and the lower glass 15.

It should be noted that the upper film 12, the lower film 14 and the battery piece 13 are all flexible structures, that is, the curvatures of the upper film 12, the lower film 14 and the battery piece 13 can be adjusted according to actual needs. Therefore, when facing roofs with different curvature requirements, only the curvatures of the upper layer glass 11 and the lower layer glass 15 are heated and bent, so that the processing difficulty of the photovoltaic tile 1 can be effectively reduced.

It will be appreciated that the cell 13 may be a single piece of flexible crystalline silicon cell or a plurality of flexible crystalline silicon cells laid between the upper glass 11 and the lower glass 15. When the structure of the plurality of battery pieces 13 is adopted, the battery pieces 13 can be electrically connected through a plurality of bus bars 18, the plurality of bus bars 18 are finally assembled in the junction box 17, and the junction box 17 can be connected with the lower glass 15 in a bonding mode; the junction boxes 17 between the plurality of photovoltaic tiles 1 may be interconnected by wires.

In one embodiment of the present utility model, as shown in fig. 14 to 16, the outer sides of the frames 19 located at both sides of the photovoltaic tile 1 are provided with blocking grooves 190. Thus, when the photovoltaic tile 1 is assembled, the photovoltaic tile 1 can be engaged with the side frame 19 of the adjacent photovoltaic tile 1 through the blocking groove 190 to form a limiting structure.

It will be appreciated that the side frame 19 is used to sandwich the upper and lower sheets of glass 11, 15 on one side and on the other side.

In this embodiment, the baffle slot 190 is arranged in a plurality of ways, including but not limited to the following two ways.

Setting mode one: as shown in fig. 14 and 16, the outer side of the frame 19 includes an upper end and a lower end, wherein the lower end may be bent downward to extend to form a buckle 191, the buckle 191 may be formed into a blocking groove 190 by a bent structure, and an opening of the blocking groove 190 is directed toward the center of the photovoltaic tile 1. When the photovoltaic tiles 1 are assembled, any two adjacent photovoltaic tiles 1 can be a first photovoltaic tile and a second photovoltaic tile respectively, wherein the first photovoltaic tile is overlapped on the upper surface of one end of the second photovoltaic tile through one end; the first photovoltaic tile can be engaged with the outer upper end of the frame 19 at the side of the second photovoltaic tile through a blocking groove 190 formed by a buckle 191.

Specifically, as shown in fig. 14, a baffle 192 is further disposed at the upper end of the outer side of the frame 19, so that when the photovoltaic tile 1 is assembled, the baffle 192 at the upper end of the outer side of the frame 19 at the side of the second photovoltaic tile can be engaged with the baffle 190 formed by the buckle 191 of the first photovoltaic tile; furthermore, the limit points formed by the abutting of the end parts of the baffle plates 192 and the baffle grooves 190 of the adjacent photovoltaic tiles 1 can be far away from the side parts of the upper layer glass 11 and the lower layer glass 15 of the clamped second photovoltaic tile, so that the safety of the photovoltaic tiles 1 in long-time use can be ensured.

Setting mode II: as shown in fig. 15, the outer side of the frame 19 includes an upper end and a lower end, wherein the upper end may be bent upward to be provided with a buckle 191, the photovoltaic tile 1 may form a blocking groove 190 by the buckle 191 bent on the frame 19 on both sides, and the opening direction of the blocking groove 190 is directed to the center of the photovoltaic tile 1. When the photovoltaic tiles 1 are assembled, any two adjacent photovoltaic tiles 1 can be a first photovoltaic tile and a second photovoltaic tile respectively, wherein the first photovoltaic tile is overlapped on the upper surface of one end of the second photovoltaic tile through one end; the first photovoltaic tile can be engaged with the blocking groove 190 formed by the buckle plates 191 on both sides of the second photovoltaic tile through the lower ends of the frames 19 on both sides.

It will be appreciated that, since the dimensions of the photovoltaic tiles 1 are uniform, when the adjacent photovoltaic tiles 1 are stacked, a gap exists between the lower end of the frame 19 of the first photovoltaic tile and the upper end of the frame 19 of the second photovoltaic tile, and therefore the buckle 191 needs to be bent, so that when the first photovoltaic tile is clamped with the blocking grooves 190 formed by the frames 19 on both sides of the second photovoltaic tile, the frames 19 on the side of the second photovoltaic tile can be abutted against the outer sides of the side frames 19 of the upper photovoltaic tile 1 through the ends of the buckle 191.

In one embodiment of the present utility model, as shown in fig. 3, an upper buckle cover 103 is installed at the middle part of the upper surface of the first end of the photovoltaic tile 1, and a lower buckle cover 104 is installed at the middle part of the lower surface of the second end of the photovoltaic tile 1. Thus, when the photovoltaic tiles 1 are assembled, the photovoltaic tiles 1 can be buckled with the lower buckling covers 104 of the adjacent photovoltaic tiles 1 through the upper buckling covers 103 to form a limiting structure.

It should be understood by those skilled in the art that the first end of the photovoltaic tile 1 is the end that is downward in the direction of the slope of the roof 600, and the corresponding other end is the second end of the photovoltaic tile 1.

It will be appreciated that the specific structure of the upper buckle cover 103 and the lower buckle cover 104 is various, one common structure is shown in fig. 3, and the upper buckle cover 103 and the lower buckle cover 104 are each generally in a "U" shape or a "U" -like shape, however, other shapes are also possible, and the design of applicability can be made according to the buckling arrangement of the upper buckle cover 103 and the lower buckle cover 104, and the arrangement shape of the upper buckle cover 103 and the lower buckle cover 104 is not limited in the embodiments of the present utility model. Both ends of the upper buckle cover 103 and the lower buckle cover 104 are provided with buckles, and the width of the upper buckle cover 103 is slightly larger than that of the lower buckle cover 104, or the width of the lower buckle cover 104 is slightly larger than that of the upper buckle cover 103, so that the upper buckle cover 103 and the lower buckle cover 104 can be mutually covered, and further the buckling of each other is realized through the buckles at both ends, so that the assembled photovoltaic tile 1 cannot slide along the radian direction, and the stability of the integral structure of the assembled photovoltaic tile 1 is improved. And the upper buckle cover 103 and the lower buckle cover 104 have simple structures, and are convenient to process and maintain daily.

It should be noted that the upper and lower surfaces of the photovoltaic tile 1 are the upper and lower glass 11, 15, respectively. Thus, in at least one embodiment, the upper and lower covers 103, 104 can be adhesively secured to the upper and lower surfaces of the photovoltaic tile 1, respectively.

In one embodiment of the present utility model, as shown in fig. 4 to 11, a bumper strip 10 made of flexible material is mounted on the upper surface of the first end of the photovoltaic tile 1; the photovoltaic tiles 1 may support the second ends of adjacent photovoltaic tiles 1 by means of the bumper strips 10.

It will be appreciated that during the assembly and laying of the photovoltaic tiles 1, the photovoltaic tiles 1 are typically laid manually, and thus, it may happen that the photovoltaic tiles 1 are hit to another adjacent photovoltaic tile 1 at a short distance. This easily causes breakage of the lower glass 15 of the upper photovoltaic tile 1 after striking the upper glass 11 of the lower photovoltaic tile 1. Therefore, in order to reduce the possibility that the photovoltaic tile 1 is damaged in the process of assembly and laying, the anti-collision strip 10 made of flexible materials can be arranged on the upper surface of the photovoltaic tile 1, so that when the photovoltaic tile 1 collides with the anti-collision strip 10 in the process of assembly, the anti-collision strip 10 made of flexible materials can absorb impact force through elastic deformation, the purpose of buffering is achieved, and the contact between the anti-collision strip 10 made of flexible materials and the lower glass 15 of the photovoltaic tile 1 can be reduced, and the abrasion caused by shaking of the photovoltaic tile 1 in the process of assembly can be reduced.

In this embodiment, as shown in fig. 7, the bumper strip 10 may be adhered to the upper surface of the upper glass 11 along the circumferential arc direction. Furthermore, the bumper strip 10 may be a whole section attached to the upper surface of the upper glass 11; the glass may be bonded to the upper surface of the upper glass 11 at a multi-stage interval.

In particular, the bumper strip 10 can have a variety of specific configurations, including but not limited to the two types described below.

Structure one: as shown in fig. 9, the bumper strip 10 is made of rubber, and the bumper strip 10 is of a hollow structure. So that the bumper strip 10 can be deformed flat to achieve cushioning when the photovoltaic tile 1 is brought into contact with the bumper strip 10.

And (2) a structure II: as shown in fig. 10 and 11, the upper surface of the bumper strip 10 is provided with a plurality of flexible support ribs so that the bumper strip 10 can be cushioned by bending deformation of the support ribs when the bumper strip 10 is in contact with the photovoltaic tile 1.

Another aspect of the utility model provides a photovoltaic roofing installation system, as shown in fig. 1 and 2, wherein an alternative embodiment includes multiple sets of photovoltaic tiles 1 and multiple sets of drainage tiles 2 mounted to a roof 700. The number of the photovoltaic tiles 1 included in each group is plural, and the plurality of photovoltaic tiles 1 in each group can be assembled by adopting the above-mentioned stacked assembly structure. The photovoltaic tiles 1 of the plurality of groups may be arranged at intervals in the width direction of the roof 700 when the roof 700 is laid. Meanwhile, the drainage tiles 2 of each group are respectively positioned between two adjacent groups of photovoltaic tiles 1, so that the adjacent photovoltaic tiles 1 along the gradient direction of the roof 700 are in transition through the drainage tiles 2. The drain tile 2 can be made of metal, such as aluminum-magnesium-manganese alloy, or nonmetal, such as hard plastic. The photovoltaic tiles 1 are arranged in an upward arch manner, and the drainage tiles 2 are arranged in a downward concave manner, so that a wavy structure can be formed between the plurality of groups of photovoltaic tiles 1 and the plurality of groups of drainage tiles 2 in the gradient direction perpendicular to the roof 700. Meanwhile, water leakage can occur at the joint of the drainage tile 2 and the photovoltaic tile 1, and the adjacent side parts of the drainage tile 2 and the photovoltaic tile 1 can be matched through a waterproof structure.

It should be appreciated by those skilled in the art that the sloped direction of roof 600 refers to the direction from the ridge to the eave and may be considered the lengthwise direction of roof 600, and that the direction along which roof 600 extends perpendicular to the sloped direction may be considered the widthwise direction of roof 600.

It can be understood that by adopting the photovoltaic tile 1 to be arranged in an upward arch manner, adopting the drainage tile 2 to be arranged in a downward concave manner, the photovoltaic tile 1 positioned at the wave crest can be used for generating electricity in the wave-shaped photovoltaic roof formed by the photovoltaic tile 1 and the drainage tile 2 positioned at the wave crest, the drainage tile 2 positioned at the wave trough is used for carrying out tissue drainage, the drainage height of the photovoltaic roof can be properly improved by the drainage structure of the wave trough, and the drainage capacity of the photovoltaic roof can be effectively improved, so that water leakage is reduced. And the photovoltaic roofing is along the wave structure of perpendicular to roofing 700 gradient directions through the mutual interval cooperation formation of a plurality of single curved photovoltaic tiles 1 of camber and a plurality of single curved sunken drainage tiles 2, compares the photovoltaic tile of traditional integral type wave structure, the processing degree of difficulty of reduction photovoltaic tile 1 that can be great to and the laying degree of difficulty of roofing, thereby can effectually reduce the cost of photovoltaic roofing.

Meanwhile, the waterproof structure is adopted at the joint of the drainage tile 2 and the photovoltaic tile 1, so that corrosion inside the photovoltaic roof caused by rainwater entering into the joint can be reduced or avoided.

In this embodiment, as shown in fig. 1, 2 and 11, a plurality of battens 500 extending along a direction perpendicular to the gradient direction of the roof 700 are arranged at intervals along the gradient direction of the roof 700, and the battens 500 may be made of metal, such as aluminum alloy, or nonmetal, such as wood. Meanwhile, a plurality of water-flowing strips 600 extending along the gradient direction of the roof 700 are arranged at intervals along the gradient direction perpendicular to the roof 700, and the water-flowing strips 600 can be made of metal, such as aluminum alloy, or nonmetal, such as wood. The two ends of the photovoltaic tile 1 and the drainage tile 2 along the length direction can be fixed to the batten 500 through the fastener 800; the batten 500 may be secured to the water bar 600 by fasteners 800 such that the photovoltaic roofing gap formed by the laying of the photovoltaic tiles 1 and the drainage tiles 2 is above the roof 700. Thereby being convenient for laying the photovoltaic roof and ensuring the use safety.

It will be appreciated that, since the drainage tile 2 adopts a structure recessed downward, if the drainage tile 2 is directly installed on the roof 700, the installation heights of the two sides of the drainage tile 2 may be too high, so that the installation or the installation of the drainage tile 2 cannot be difficult. Thus, by providing battens 500, the installation operation of the fastener 800 can be facilitated to facilitate the installation of the drainage shoe 2 as well as the photovoltaic shoe 1. Moreover, the batten 500 can contact with the lower vertex of the outer side wall of the drainage tile 2, so as to support the drainage tile 2.

Meanwhile, by connecting the batten 500 with the photovoltaic tile 1 and the drainage tile 2 along the extension perpendicular to the gradient direction of the roof 700, the number of battens 500 can be effectively reduced compared with the arrangement along the gradient direction of the roof 700.

For ease of understanding, the description may be by way of parameters. Assume that there are m groups of photovoltaic tiles 1, each group comprising n photovoltaic tiles 1. If battens 500 are arranged in a direction perpendicular to the slope of roof 700, the number of battens 500 required is typically n+1; if battens 500 are arranged in the direction of the slope of the roof 700, the number of battens 500 required is typically 2 m. Under the condition that the values of m and n are larger, the required quantity is obviously smaller when the batten 500 is arranged in the gradient direction perpendicular to the roof 700, and the laying cost of the photovoltaic roof can be effectively reduced.

Meanwhile, since the batten 500 is disposed in a direction perpendicular to the slope of the roof 700, if the batten 500 is directly fixed to the roof 700 by the fastener 800, drainage of the roof 700 itself may be hindered. Thus, in arranging a plurality of water strips 600 extending along the gradient direction of the roof 700 at intervals along the gradient direction perpendicular to the roof 700, the battens 500 can be mounted on the water strips 600 by the fasteners 800; the spacing between the water bars 600 may be set larger to further reduce costs.

Because the two sides of the drainage tile 2 are upward-warped structures, the connection between the drainage tile 2 and the hanging tile 500 is convenient; in one embodiment of the utility model, as shown in fig. 2, 11 and 14 to 17, the photovoltaic roofing installation system of the utility model further comprises a plurality of connectors 3; the connectors 3 are respectively located right below the two ends of the photovoltaic tile 1, and the extending direction of the connectors 3 is parallel to the battens 500. The connecting piece 3 comprises a first connecting edge with a raised middle part and a second connecting edge which is positioned at two sides and is connected with the first connecting edge in an L shape. The connecting piece 3 can be connected with the batten 500 through the second connecting edge to form a fastening piece 800; while the drainage shoe 2 may be connected to the side of the first connection edge of the connection member 3 by means of the fastener 800.

It will be appreciated that, in order to reduce interference between the rim 19 and the drainage shoe 2, as shown in fig. 12 to 17, the drainage shoe 2 may be fixed to the side of the first connection edge of the connection member 3 by a fixing portion 21 provided in a side step.

In this embodiment, the photovoltaic tile 1 may also be connected to the batten 500 through the connecting piece 3, and generally, there are two ways in which the photovoltaic tile 1 is connected to the connecting piece 3 in a matching manner; first kind: the photovoltaic tile 1 is connected with the connecting piece 3 through the side frames 19 on two sides; second kind: the photovoltaic tile 1 may be connected to the connector 3 via a support structure through the middle of the underside of the first end.

It can be appreciated that, since the two side frames 19 of the photovoltaic tile 1 need to form a limiting structure required for assembly, if the photovoltaic tile 1 is cooperatively connected with the connecting piece 3 through the frames 19, the structure of the frames 19 is relatively complex, and thus the processing is inconvenient. Therefore, the matching connection of the photovoltaic tile 1 and the connecting piece 3 in the utility model preferably adopts the second mode; and, because the maximum atress position of photovoltaic board 1 is located first end when assembling photovoltaic board 1, then through setting up bearing structure in first end, can the at utmost support photovoltaic board 1.

In one embodiment of the present utility model, as shown in fig. 7, 8 and 11, the supporting structure includes a hanging plate 16 mounted on the middle of the lower side of the first end of the photovoltaic tile 1, and a supporting member 4 fixedly mounted on the connecting member 3, where the supporting member 4 can support and limit the hanging plate 16 through the upper end.

In this embodiment, as shown in fig. 6 to 8, since the lower surface of the photovoltaic tile 1 is the lower glass 15, the hanging plate 16 may be connected to the lower glass 15 of the photovoltaic tile 1 by an optional bonding manner, and the bonding position of the hanging plate 16 is set at a distance from the position of the junction box 17.

Specifically, as shown in fig. 6 to 11, the hanging plate 16 and the lower glass 15 are bonded by a glue layer. The adhesive layer may include a structural adhesive 101 and a double-sided tape 102, the double-sided tape 102 being disposed around the structural adhesive 101 in a circle. Therefore, the structural adhesive 101 can firmly bond the hanging plate 16 with the lower surface of the lower glass layer 15, and the double-sided tape 102 has the functions of reducing overflow of the structural adhesive 101 and the like.

It should be appreciated that the configuration of the hanging plate 16 may be selected according to the actual needs, and only the photovoltaic tile 1 is required to be supported. Meanwhile, the hanging plate 16 may be made of metal or nonmetal, and in at least one embodiment, the hanging plate 16 may be made of aluminum alloy.

In this embodiment, as shown in fig. 7, 8 and 11, the hanging plate 16 is bonded to the lower glass 15 at the lower side of the first end of the photovoltaic tile 1 through a part of the plate section, and the plate section of the hanging plate 16 extending to the outer side of the first end of the photovoltaic tile 1 is provided with a hanging port 160. The support 4 can support the photovoltaic tile 1 by the hanging plate 421 at the top penetrating the hanging port 160 of the hanging plate 16.

Specifically, as shown in fig. 11 and 12, the support 4 includes a first support plate 41, a second support plate 42, and a third support plate 43; the first supporting plate 41 is perpendicular to the roof 700, the second supporting plate 42 is fixedly connected to the upper end of the first supporting plate 41, and the second supporting plate 42 can be attached to the lower side of the hanging plate 16, so that the supporting area of the supporting piece 4 on the photovoltaic plate 1 is increased; the hooking plate 421 can be disposed on the second support plate 42, so that the hooking plate 421 can be fastened to the hooking port 160 in a state where the second support plate 42 is attached to the hooking plate 16, so as to ensure stability of the support structure of the photovoltaic tile 1.

As can be seen from the above description and fig. 2 and 14 to 17, the connection position of the connecting piece 3 and the batten 500 is located below two sides of the drainage tile 2, i.e. the connection position of the connecting piece 3 and the batten 500 is blocked by the drainage tile 2; the provision of waterproof structures to the connection locations of the connection piece 3 and the batten 500 is reduced in the laying of the photovoltaic roofing. The drainage tile 2 can extend to the lower parts of the side frames 19 on the two sides of the photovoltaic tile 1 through the fixing parts 21, so that the photovoltaic tile 1 is fixed on the connecting piece 3 through the side frames 19 together with the fixing parts 21 of the drainage tile 2, or the drainage tile 2 is independently fixed on the connecting piece 3 below the side frames 19 of the photovoltaic tile 1 through the fixing parts 21. In either way, the connection position between the drainage tile 2 and the connector 3 is exposed to the side of the photovoltaic tile 1, and a waterproof structure is required to be arranged between the photovoltaic tile 1 and the adjacent side of the drainage tile 2 for waterproofing.

In the present utility model, the specific structure of the waterproof structure has various embodiments, including but not limited to the following two.

Embodiment one: the photovoltaic tile 1 forms a waterproof edge through the self structure of the side-mounted frame 19, and the waterproof edge can shield the connection position of the drainage tile 2 and the roof 700 to form a waterproof structure.

Specifically, when the above arrangement mode is adopted for the baffle groove 190, as shown in fig. 14 and 16, the photovoltaic tile 1 may be folded down by the buckle 191 at the lower end of the outer side of the frame 19 to form a waterproof edge, and the waterproof edge may cover the connection position between the drainage tile 2 and the roof 700 to form a waterproof structure.

It can be understood that, in the two adjacent photovoltaic tiles 1, the photovoltaic tile 1 positioned at the lower part can shield the connection position of the drainage tile 2 and the connecting piece 3 through the pinch plate 191 which is bent downwards at the lower end of the outer side of the frame 19; the photovoltaic tile 1 positioned at the upper part can guide water flow to the pinch plate 191 of the photovoltaic tile 1 at the lower part through the pinch plate 191 bent downwards at the lower end at the outer side of the outer frame 19 until the water is guided into the trough space of the drainage tile 2 and discharged under the eave.

When the second mode of arrangement is adopted in the retaining groove 190, as shown in fig. 15, the frame 19 passes through the baffle 192 at the lower end of the outer side to form a waterproof edge, and the waterproof edge can shield the connection position of the drainage tile 2 and the roof 700 to form a waterproof structure.

It will be appreciated that rainwater on the upper surface of the photovoltaic tile 1 can drain down to the eave through the blocking groove 190 formed by the buckle 191 bent upward at the upper end of the outer side of the frame 19. The baffle 192 of the lower end in the outside can shelter the connection position of the drainage tile 2 and the roof 700 to ensure that rainwater on the side part of the frame 19 of the photovoltaic tile 1 can be guided into the trough space of the drainage tile 2 along the baffle 192 and is discharged under the eave.

Embodiment two: the photovoltaic roofing 700 installation system includes a plurality of flashing fasteners 91; the two ends of the water-covering fastener 91 are respectively connected with the frame of the photovoltaic tile 1 and the fixing part 21 of the drainage tile 2 in a matched manner, so that the water-covering fastener 91 can shield the connection position of the drainage tile 2 and the roof 700 to form a waterproof structure.

In this embodiment, there are various ways of fitting the two ends of the water-covering fastener 91, including but not limited to the following two ways.

The first matching mode is as follows: as shown in fig. 16, one side of the water-covering fastener 91 may extend to the inner side of the photovoltaic tile 1 together with the fixing portion 21 on the side of the drainage tile 2 and be fixedly connected to the connector 3. The other side of the waterproof fastener 91 can be bent upwards and matched with the side frame 19 of the photovoltaic tile 1, so that a waterproof structure for shielding the connection position of the drainage tile 2 and the roof 700 is formed.

Specifically, as shown in fig. 16, the side of the waterproof fastener 91 that is bent upward may be attached to the frame 19 on the side of the photovoltaic tile 1. Alternatively, the side of the water-covering fastener 91 that is bent upward may be engaged with a clip 193 provided on the frame 19 on the side of the photovoltaic tile 1. In either way, it is only necessary to ensure that the connection structure formed between the frame 19 and the draping fastener 91 can shield the connection position between the drainage tile 2 and the connector 3.

It can be appreciated that the clamping block 193 can be disposed on the baffle 192 of the frame 19 or the buckle 191 of the frame 19, and the specific arrangement mode of the baffle 192 and the buckle 191 can be selected, i.e. the clamping block 193 is disposed on the baffle 192 or the buckle 191 which is bent downwards. When the water-covering fastener 91 is fastened to the fixture block 193, the water-covering fastener 91 is preferably engaged with the fixture block 193 on the side of the photovoltaic tile 1 located at the upper part.

And the matching mode II is as follows: as shown in fig. 17, the underside of the water-covering fastener 91 may be fastened to a fastening cavity 920 provided on the upper surface of the fixing portion 21 of the drainage tile 2. The upside of the water-covering fastener 91 can be inserted into the slot 194 arranged on the side frame 19 of the photovoltaic tile 1, and then the water-covering fastener 91 can form a waterproof structure for shielding the connection position of the water-draining tile 2 and the roof 700 through the cooperation of the side frame 19 and the water-draining tile 2.

Specifically, as shown in fig. 17, the photovoltaic roofing system further includes a plurality of bases 92, one side of the bases 92 may extend to the inner side of the photovoltaic tile 1 together with the fixing portion 21 on the side portion of the drainage tile 2 and be fixedly connected to the connecting piece 3, and a fastening cavity 920 is disposed on the other side of the bases 92, so that the lower end of the draping fastener 91 may be matched with the fastening cavity 920 disposed on the bases 92.

It will be appreciated that the drainage tile 2 is generally integrally formed, so that the fastening cavity 920 is to be formed at the side portion of the drainage tile 2, and the drainage tile 2 needs to be secondarily formed, which results in an increase in difficulty of the process of the drainage tile 2 and further an increase in processing cost. By adding the base 92, the processing difficulty of the drainage tile 2 can be effectively reduced, so that the installation of the water-covering fastener 91 is convenient.
