[0001] This application relates primarily to the field of photovoltaic technology, and more particularly to photovoltaic profiles, photovoltaic roof tile modules, and photovoltaic roof mounting systems. [Background technology]

[0002] Photovoltaic roof mounting systems use multiple interconnected photovoltaic modules to form a photovoltaic power generation system installed on a roof. When it rains or snows, rainwater can seep into the photovoltaic modules through the gaps between the modules and into the photovoltaic profiles of the fixed photovoltaic modules. To avoid this problem, rainwater must be effectively drained from the photovoltaic modules and the photovoltaic profiles. While installing drainage channels on the photovoltaic profiles allows for rainwater to be drained, photovoltaic profiles with drainage channels currently lack the ability to effectively drain water seeping in through the gaps between the upper and lower roof tiles, and the processing of the module frame is generally complicated.

[0003] Therefore, providing a photovoltaic profile and a photovoltaic roof mounting system that is simple in structure and can efficiently drain rainwater is an urgent problem to be solved. Summary of the Invention [Problem to be solved by the invention]

It is also required to understand the present application not only by the actual terms used but also by the meanings contained in each term.

[0029] Next, the photovoltaic member and the photovoltaic roof mounting system of the present application will be described using specific examples.

[0030] Fig. 1A is a perspective view of a photovoltaic panel according to an embodiment of the present invention, and Fig. 1B is a plan view of the photovoltaic panel shown in Fig. 1A. As shown in Fig. 1A and Fig. 1B, the photovoltaic panel 100 includes a first frame 110, a second frame 120, a third frame 130 and a fourth frame 140, each of which forms an enclosed area 10, and a photovoltaic module 20 can be attached to the enclosed area through each of the frames.

[0031] Specifically, refer to FIG. 3A, which shows a schematic plan view of the first frame, and FIG. 3B, which shows a schematic cross-sectional view of the first frame in FIG. 3A taken along a plane perpendicular to the first direction D1. The first frame 110 extends along the first direction D1, and each of its opposing ends along the first direction D1 has a corresponding first joint corner 111. As shown in FIG. 3A, the two first joint corners 111 each have a hypotenuse 111a. As shown in FIG. 2, which is a partial enlargement of a portion A in FIG. 1B, the first joint corners 111 have a joint angle α. The joint angle α is the angle between the hypotenuse 111a and a line parallel to the first direction D1, and the joint angle α is greater than 45° and less than 90°. The left first joint corner of the first frame 110 in FIG. 1B also has a joint angle α.

[0032] As shown in FIG. 3B, the first frame 110 has a first mounting position 112 and a first drainage groove 113 that face each other along the second direction D2, and the first mounting position 112 and the first drainage groove 113 are adjacent to two side surfaces (114a and 114b) of the corner bracket mounting cavity 114 that face each other along the first direction D1. As shown in FIG. 3A, the corner bracket mounting cavity 114 can be used to mount a corner bracket 150. Note that the corner bracket 150 in FIG. 3A is not part of the first frame 110, and this description also applies to the following description, so it will not be described below.

[0033] The first mounting position 112 has a bottom surface 112a, a side surface 112b, and a side surface 112c, the side surface 112b and the side surface 112c being opposite each other and connected to the bottom surface 112a, forming an opening 112d, which faces the third frame 130, as shown in FIG. 1B. The opening 112d can be used to mount a photovoltaic stack.

[0034] The first drainage groove 113 has a bottom surface 113a, one end of which is connected to the bottom surface 114c of the first frame, which is also the bottom surface of the corner bracket mounting cavity 114, and the other end of which extends away from the first mounting position 112. A protrusion 113b is provided on the end of the bottom surface 113a, which is away from the corner bracket mounting cavity 114. The bottom surface 113a, the protrusion 113b, and one side surface 114a of the corner bracket mounting cavity 114 collectively constitute the first drainage groove 113. The bottom surface 113a and the protrusion 113b also function as a fixing plate, and are used to connect the fixing plate to the roof using a fixing device when installing the photovoltaic member on the roof. Specifically, as shown in FIG. 3B, the bottom surface 113a and the protrusion 113b collectively constitute the first fixing plate 115.

[0035] The first frame of the present application may be implemented as the structure of FIG. 3C.

[0036] Referring to the cross-sectional schematic diagram of the first frame of one embodiment shown in Figure 3C, unlike the first frame of Figure 3B, the first mounting position 112 is located to the left of the corner bracket mounting cavity 114 along the third direction D3, and the upper surface 114d of the corner bracket mounting cavity 114 simultaneously functions as one side of the first mounting position 112.

[0037] FIG. 4A is a schematic plan view of a second frame according to one embodiment, and FIG. 4B is a schematic cross-sectional view of the second frame taken along a plane perpendicular to the second direction D2 in FIG. 4A . As shown in FIG. 4A , second joint corners 121 are provided at opposite ends of the second frame 120 along the second direction D2, and each second joint corner 121 has a hypotenuse 121a. As shown in FIG. 2 , the second joint corner 121 has a joint angle β, which is the angle between the hypotenuse 121a and a line parallel to the second direction D2, and the joint angle β is greater than 0° and less than 45°. The lower second joint corner of the second frame 120 in FIG. 1B also has a joint angle β.

[0038] Here, the relationship between the joint angle α and the joint angle β will be described. As shown in FIG. 2, the first joint corner 111 on the right side of the first frame 110 is connected to the second joint corner 121 adjacent to the second frame 120, and this connection can be made using, for example, a corner bracket. As shown in FIGS. 3A and 4A, the hypotenuse 111a of the first joint corner 111 and the hypotenuse 121a of the second joint corner 121 have the same length and are bonded to each other. After the hypotenuse 111a and the hypotenuse 121a are bonded to each other, the sum of the joint angle α and the joint angle β is preferably 90°. It should be understood that the sum of the joint angle α and the joint angle β may be 90±5°.

[0039] Next, as shown in FIG. 4B , the second frame 120 further includes a second mounting position 122 and a second drainage groove 123, which face each other along the first direction D1. The second mounting position 122 is provided on the side wall 124 a of the corner bracket mounting cavity 124 and is spaced apart from the bottom surface 124 b of the corner bracket mounting cavity 124. Like the first mounting position described above, the second mounting position 122 has a groove-like structure. As shown in FIG. 1B , the second mounting position 122 has an opening 122 a facing the fourth frame 140, which can be used to connect to a photovoltaic module. For further details about the second mounting position 122, please refer to the description of the first mounting position described above.

[0040] A bottom surface 123a of each second drainage groove 123 is adjacent to a bottom surface 124b of the corner bracket mounting cavity 124, and the bottom surface 123a is connected to a side wall 123b away from one end of the corner bracket mounting cavity, and a side wall 123c is provided between the side wall 123b and the corner bracket mounting cavity 124 along the second direction D1, thereby forming two adjacent second drainage grooves 123. Based on Figure 4B, it can be understood that the number of second drainage grooves 123 can be increased or decreased.

[0041] The second frame of the present application may be implemented as the configuration of FIG. 4C.

[0042] Referring to the cross-sectional schematic diagram of the second frame of one embodiment shown in Figure 4C, unlike the second frame of Figure 4B, the second mounting position 122 is adjacent to the corner mounting cavity 124 along the third direction D3, and the bottom surface 122b of the second mounting position 122 is formed by the side surface 124c of the corner bracket mounting cavity 124 extending upward along the third direction D3, and the top surface 124d of the corner bracket mounting cavity 124 simultaneously functions as one side surface of the second mounting position 122.

[0043] As shown in FIG. 2, in some embodiments, a method for connecting a first frame 110 and a second frame 120 includes using a corner bracket 150 to connect a first joint corner 111 and an adjacent second joint corner 121. Specifically, the corner bracket 150 has a first plug 151 and a second plug 152, and one end of the first plug 151 is connected to one end of the second plug 152. As shown in FIGS. 2 and 3B, the first plug 151 is inserted into the corner bracket mounting cavity 114 of the first frame 110, and as shown in FIGS. 2 and 4B, the second plug 152 is inserted into the corner bracket mounting cavity 124 of the second frame 120. In this manner, the first frame 110 and the second frame 120 are connected to each other.

[0044] For convenience of explanation, corner brackets are depicted in Figures 1B and 2. It should be understood that, since the corner brackets are installed in the corner bracket mounting cavities, in a real situation the corner brackets located in the corner bracket mounting cavities cannot be seen from the outside of the photovoltaic mold.

[0045] 2, the dimension W1 of corner bracket mounting cavity 114 of first frame 110 along the second direction D2 is greater than the dimension W2 of corner bracket mounting cavity 124 of second frame 120 along the first direction D1, where W1 = W2 × tan?. As shown in FIGS. 2 and 3B, the distance between opening 112d and side wall 114a along the second direction D2 is W3, and as shown in FIGS. 2 and 4B, the distance between opening 122a and side wall 124c along the first direction D1 is W4, whereby the distances W3 and W4 have the relationship W3 = W4 × tan?.

[0046] As shown in Figure 2, the first drainage groove 113 of the first frame 110 and the second drainage groove 123 of the second frame 120 are connected at the connection point of the two frames, and rainwater in the first drainage groove 113 flows through the second drainage groove 123 and is discharged from the photovoltaic member.

[0047] FIG. 5A is a schematic plan view of a third frame 130 according to one embodiment, and FIG. 5B is a schematic cross-sectional view of the third frame 130 taken along a plane perpendicular to the first direction D1. As shown in FIG. 5A, the third frame 130 has corresponding third joint corners 131 at opposite ends along the first direction D1, each of which has a hypotenuse 131a. As shown in FIGS. 1B, 2, and 5A, similar to the connection between the first frame 110 and the second frame 120, the second joint corner 121 of the second frame 120 closest to the third frame 130 is joined with the adjacent third joint corner 131, thereby achieving the connection between the second frame 120 and the third frame 130. In some embodiments, corner brackets 150 can be used to connect the second frame 120 and the third frame 130.

[0048] 5B, the third frame 130 has a second fixing plate 135, one end of which is connected to the bottom surface 133b of the third frame 130, which is also the bottom surface of the corner bracket mounting cavity 133, and the other end of which extends in the second direction D2. The second fixing plate 135 is used to fix the third frame, and this portion will be described in detail later.

[0049] As shown in FIG. 2, the joint angle α of the first frame 110 is larger than the joint angle β of the second frame 120, and the technical effect of the size relationship of the joint angles will be described here.

[0050] First, as shown in Figures 3A and 3B, the first frame 110 has a first double plate 116. As shown in Figure 3B, the first double plate 116 has an upper surface 114d of the corner bracket mounting cavity 114 and a side surface 112b of the first mounting position 112. As shown in Figures 5A and 5B, the third frame 130 has a second double plate 136. As shown in Figure 5B, the second double plate 136 has a second fixing plate 135 and a bottom surface 133a. In other words, the second fixing plate 135 and the bottom surface 133a function together as the second double plate 136.

[0051] Next, refer to FIG. 7A, a cross-sectional view of an embodiment after the first and third frames are overlapped. In this embodiment, two photovoltaic sections are installed on a sloped roof 40, with the third frame 130 of the right photovoltaic section positioned above the first frame 110 of the left photovoltaic section. The second overlapping plate 136 of the third frame 130 overlaps the first overlapping plate 116 of the first frame 110. As shown in FIG. 3B, the first overlapping plate 116 has a dimension W3 along the second direction D2 in a plane away from the corner bracket mounting cavity 114. As shown in FIG. 5B, the second overlapping plate 136 has a dimension W5 along the second direction D2, where W3 is equal to W5. As shown in FIGS. 3B, 5B, and 7A, when the first frame 110 and the third frame 130 are overlapped, the first overlapping plate 116 and the second overlapping plate 136 overlap, ensuring stable overlap between adjacent photovoltaic sections.

[0052] From the above description, it can be seen that the first double plate 116 of the first frame 110 is covered by the second double plate 136 of the third frame 130, and therefore the first double plate 116 of the first frame 110 cannot be observed. Returning to FIG. 2 , by making the joint angle α larger than the joint angle β, the dimension W3 of the first double plate 116 is increased and the visible dimension of the second frame 120 is reduced. Although the dimension W3 of the first double plate 116 increases, because the first double plate 116 is covered by the second double plate 136, increasing the dimension W3 of the first double plate 116 has little effect on the aesthetic appearance of the photovoltaic mold, and reducing the visible dimension of the second frame 120 improves the aesthetic appearance of the photovoltaic mold.

[0053] As shown in FIG. 5B , in one embodiment, the surface 135a of the second fixing plate 135 facing the third mounting position 132 is an inclined surface that slopes downward along the second direction D2. As shown in FIG. 7A , when overlapping adjacent photovoltaic sections, a mounting base 160 is used to secure the overlapped two photovoltaic sections. The mounting base 160 has an opposing mounting edge 161 for connecting to the roof 40 and a pressure edge 162 that presses against the surface 135a of the third frame 130 and applies pressure to the third frame 130 toward the first frame 110. In this way, the mounting base 160 achieves a pressure-contact effect between the first frame 110 and the third frame 130 of the adjacent photovoltaic section. The inclined surface 135a helps to press the third frame 130 into the gap between the pressing edge 162 and the first overlapping plate 116 along the roof slope direction D4.

[0054] As shown in Fig. 5B, the third frame 130 further includes a third mounting position 132. In Fig. 5B, the third mounting position 132 includes a bottom surface 132a, a side surface 132b, and a side surface 132c. The bottom surface 132a overlaps with one side surface 133a of the corner bracket mounting cavity 133, and the side surfaces 132b and 132c face each other to form an opening 132d. When connecting the photovoltaic module and the photovoltaic molded member, one side of the photovoltaic module 20 is inserted into the space between the side surfaces 132b and 132c through the opening 132d.

[0055] The third mounting position 132 is not limited to the configuration shown in FIG. 5B . Referring to the cross-sectional schematic diagram of a third frame in another embodiment shown in FIG. 5C , the difference between FIG. 5C and FIG. 5B is that the third mounting position 132 in FIG. 5C has the side 132b of FIG. 5B removed, leaving the bottom 132a and side 132c. One end of the bottom 132a is connected to one end of the side 132c to form a mounting angle. When connecting the photovoltaic module to the third mounting position 132, the side 132c functions as a mounting angle used as a support plate to support the photovoltaic module. In FIG. 5B , a step 30 exists between the side 132b and the surface of the photovoltaic module 20, which can cause dust accumulation. In FIG. 5C, the side 132b of FIG. 5B is removed, thereby avoiding dust accumulation.

[0056] Another difference between Figure 5C and Figure 5B is that the third frame 130 in Figure 5C has an engagement groove 134. As shown in Figure 5C, two engagement grooves 134 are provided on both ends of the side surface 133c of the corner bracket mounting cavity 133, facing each other along the third direction D3. The engagement grooves 134 can be used to connect with a flap, which can function as a skin water plate and have a beautiful effect.

[0057] The third frame of the present application may be implemented as the configuration of FIG. 5D.

[0058] Referring to the cross-sectional view of an embodiment of a third frame shown in FIG. 5D , unlike the third frames shown in FIGS. 5B and 5C , the third frame 130 shown in FIG. 5D includes a main body 137 and a mounting engagement edge 138. As shown in FIG. 5D , the main body 137 and the mounting engagement edge 138 are engaged with each other by a snap structure 139, which can realize a detachable connection between the main body 137 and the mounting engagement edge 138. The main body 137 and the mounting engagement edge 138 may also be connected in other ways. The third mounting position 132 is provided on the main body 137, and the second fixing plate 135 is provided on the mounting engagement edge 138. Making the third frame a combination frame consisting of a main body and a mounting engagement edge is advantageous for processing the third frame.

[0059] As shown in Fig. 5D, the main body 137 has a notch 137a. The notch 137a is provided on the side surface 130f. The notch 137a is hook-shaped, and an opening is formed between the free end 137b of the hook-shaped structure and the side surface 130f. One end of the watertight seal strip 170 can be provided in the notch 137a through the opening.

[0060] Fig. 6A is a schematic plan view of a fourth frame of one embodiment, and Fig. 6B is a schematic cross-sectional view of the fourth frame on a plane perpendicular to the second direction D2 in Fig. 6A. As shown in Fig. 6A, fourth frame 140 has corresponding fourth joint corners 141 at opposite ends along the second direction D2, and each fourth joint corner 141 has a hypotenuse 141a.

As shown in FIGS. 3A, 5A, and 6A, after joining, two oblique sides 141a of the fourth frame 140 facing each other in the second direction D2 are attached to correspond to the left oblique side 111a of the first frame 110 and the left oblique side 131a of the third frame 130, respectively. The oblique sides of the third frame 130 and the fourth frame 140 have the characteristics related to the joint angle α and the joint angle β described above, and a description thereof will be omitted here.

[0062] As shown in FIG. 6B , the fourth frame 140 has a fourth mounting position 142, which has a configuration similar to that of the first mounting position, including an opening 142a through which a photovoltaic module can be inserted into the fourth mounting position 142. The fourth mounting position 142 is adjacent to a side surface 143a of the corner bracket mounting cavity 143, and as shown in FIG. 1B , the opening 142a faces toward the second frame 120. For further explanation of the fourth mounting position 142, please refer to the explanations of the first, second, and third mounting positions above.

[0063] 6B , in one embodiment, the fourth frame 140 has a cover plate 144 that faces the fourth mounting position 142 along the first direction D1. One end of the cover plate 144 is connected to the upper surface 143b of the corner bracket mounting cavity 143, and the other end extends away from the fourth mounting position 142. In some embodiments, the fourth frame 140 has several vertical plates 145 that extend along the third direction D3, and one end of the vertical plates 145 is connected to the cover plate 144.

[0064] The fourth frame of the present application may be implemented as the configuration of FIG. 6C.

[0065] Referring to the cross-sectional schematic diagram of the fourth frame shown in Figure 6C, the fourth frame 140 in Figure 6C differs from Figure 6B in the following respects: The fourth mounting position 142 is adjacent to the corner bracket mounting cavity 143 along the third direction D3, and the bottom surface 142b of the fourth mounting position 142 is formed by the side surface 143c of the corner bracket mounting cavity 143 extending upward along the third direction D3, and the top surface 143b of the corner bracket mounting cavity 143 simultaneously functions as one side surface of the fourth mounting position 142. The fourth frame 140 has a third drainage groove 146 facing the fourth mounting position 142 along the first direction D1. One end of the bottom surface 146a of the third drainage groove 146 is connected to the side surface 143c of the corner bracket mounting cavity 143, and the other end extends away from the side surface 143c. A protrusion 146b protruding in the third direction D3 is provided at the other end of the bottom surface 146a. The bottom surface 146a, the protrusion 146b, and the side surface 143c constitute the third drainage groove 146.

[0066] 7B is a cross-sectional view of the second and fourth frames after they are stacked in the embodiment. As shown in FIG. 7B, the fourth frame 140 is stacked on the second frame 120 along the third direction D3. The cover plate 144 of the fourth frame 140 covers the second drainage groove 123 of the second frame 120. The dimension L1 of the cover plate 144 along the first direction D1 is equal to the dimension L2 of the second drainage groove along the first direction D1. As shown in FIG. 7B, the vertical plate 145 of the fourth frame 140 is attached to the side surface 124c of the corner bracket mounting cavity 124 of the second frame 120. However, due to factors such as production technology and photovoltaic material mounting errors, a gap may exist between the vertical plate 145 and the side surface 124c. This allows rainwater on the surface of the photovoltaic material to penetrate into the interior of the photovoltaic material and potentially damage the photovoltaic material. The second drainage groove 123 in the second frame 120 of the present application can remove rainwater that has entered through the gaps, and can prevent the photovoltaic material from being damaged.

[0067] As shown in FIGS. 1B and 2, the first plug 151 and the second plug 152 of the corner bracket 150 are inserted into the corner bracket mounting cavity 114 at the first joint corner 111 and the corner bracket mounting cavity 124 at the second joint corner 121, respectively. In this manner, the first joint corner and the second joint corner are connected. As shown in FIG. 1B, similar to the connection method described above, the second frame 120 and the third frame 130, the third frame 130 and the fourth frame 140, and the fourth frame 140 and the first frame 110 can be connected via the corner bracket 150. In this manner, the four frames are connected sequentially, starting with the first. The connection method between the frames is not limited to the above-described method. For example, in some embodiments, the joint corners of each frame can be connected by adhesive bonding, plugging, welding, or other methods.

[0068] 1B and 5B, the opening 132d of the third mounting position 132 faces the first frame 110 along the second direction D2. In this manner, when the photovoltaic module is installed in the enclosed area 10, the first mounting position 112 of the first frame 110 and the third mounting position 132 of the third frame 130 are respectively connected to two opposing sides of the photovoltaic module along the second direction D2.

[0069] In the above embodiment, the first frame, the second frame, the third frame, and the fourth frame all have mounting positions, which are used to connect the photovoltaic modules and the photovoltaic profiles when assembling them, as will be described below.

[0070] FIG. 7C discloses a cross-sectional view taken along line B-B in FIG. 1B, and FIG. 7D discloses a cross-sectional view taken along line C-C in FIG. 1B.

As shown in FIG. 7D, both ends of the photovoltaic module 20 facing each other along the first direction D1 are respectively provided in the second mounting position 122 and the fourth mounting position 142. As described above, the photovoltaic module 20 is fixedly attached to the closed region 10 in FIG. 1B.

[0072] FIG. 8 is a schematic plan view of another embodiment of a photovoltaic panel. The difference between FIG. 8 and FIG. 1B is that the cross section of the first frame 110 in FIG. 8 is shown in FIG. 3C, the cross section of the second frame 120 in FIG. 4C, the cross section of the third frame 130 in FIG. 5D, and the cross section of the fourth frame 140 in FIG. 6C. As can be seen from the above description of FIG. 6C, the fourth frame 140 in FIG. 6C has a third drainage groove 146 compared to the fourth frame 140 in FIG. 6B. As shown in FIG. 8, when the first frame 110 is connected to the fourth frame 140, the first drainage groove 113 of the first frame 110 is connected to the third drainage groove 146 of the fourth frame 140. Also, similar to FIG. 1B, the first drainage groove 113 of the first frame 110 is connected to the second drainage groove 123 of the second frame 120. In this way, the first drain groove 113 in Figure 8 is connected at both ends along the first direction D1 to the second drain groove 123 and the third drain groove 146, respectively, so that rainwater in the first drain groove 113 can be discharged through the second drain groove 123 and the third drain groove 146, and the arrows in Figure 8 indicate the flow direction of the rainwater.

[0073] Another aspect of the present application also proposes a photovoltaic roof tile module. As shown in FIG. 1A , the photovoltaic roof tile module includes the aforementioned photovoltaic profile and a photovoltaic module 20. The first frame 110, second frame 120, third frame 130, and fourth frame 140 of the photovoltaic profile are sequentially connected to form an enclosed area 10, and the photovoltaic module 20 is installed in the enclosed area 10. The photovoltaic module 20 can be installed in the enclosed area 10 by connecting its periphery to the mounting positions of each frame. For further details about the photovoltaic roof tile module, please refer to the previous description of the photovoltaic profile, and further details will not be provided here. The photovoltaic roof tile module in the above embodiment of the present application has the technical effects of being simple in structure, easy to process, and capable of efficiently draining rainwater. The present application also proposes a photovoltaic roof mounting system.

[0074] Referring to the side view schematic of a photovoltaic roof mounting system in one embodiment shown in Figure 9, the photovoltaic roof mounting system 200 comprises at least two of the above-mentioned photovoltaic members, a photovoltaic module, and a mounting base, where the photovoltaic members are connected to the periphery of the photovoltaic modules, and the mounting base is connected to the photovoltaic members and the roof.

[0075] Specifically, as shown in Fig. 9, three photovoltaic members 211, 212, and 213 are laid on the roof 40 in sequence along the slope direction D4, and the vertical positions of the photovoltaic members 211, 212, and 213 increase sequentially. Three photovoltaic modules 221, 222, and 223 are connected to the photovoltaic members 211, 212, and 213, respectively. The photovoltaic members are connected to the roof 40 via mounting bases 230, and the outermost photovoltaic members 211 and 213 are further connected to the roof 40 via connecting structures 251 and 252, respectively. In some embodiments, the photovoltaic modules 221, 222, and 223 each include a photovoltaic stack and a stack frame for fixing the photovoltaic stack. The photovoltaic modules may be connected to the photovoltaic members via the stack frame. In other embodiments, the photovoltaic roof mounting system further includes a mounting keel 260. The mounting keel 260 is attached to the roof 40 and the photovoltaic section is secured to the mounting keel 260 via the mounting base 230 .

[0076] The overlapping method between adjacent photovoltaic profiles along the gradient direction D4 is as follows: referring to the enlarged partial views of the circular frame portion in Figure 9 shown in Figure 9 and Figure 10A, the third frame 130 of the photovoltaic profile 212 is pressed onto the first frame 110 of the photovoltaic profile 211, and the mounting edge 231 of the mounting base 230 is connected to the roof 40. For example, the mounting edge 231 can be bolted to the roof 40 by a bolt, and the pressing edge 232 of the mounting base 230 is pressed against the second stacking plate 136 of the third frame 130, and the pressing edge 232 applies pressure to the second stacking plate 136 toward the roof 40, thereby achieving the effect of pressing the first frame 110 and the third frame 130 together.

[0077] FIG. 11A is a front view of the mounting base in FIG. 9. As shown in FIG. 11, the mounting edge 231 and the pressing edge 232 are arranged opposite each other in the third direction D3 and are connected by the mounting base body 234. The mounting base 230 further includes a ridge 233, one end of which is connected to the mounting edge 232 and the other end of which extends in the same direction as the pressing edge 232. As shown in FIGS. 3B and 10A, the ridge 233 is pressed against the first drainage groove 113 of the first frame 110. This improves the stability of the connection between the photovoltaic profile and the roof. As shown in FIG. 10A, there is a gap 50 between the ridge 233 and the corner bracket mounting cavity 114. Therefore, even if the ridge 233 is pressed against the first drainage groove 113, the drainage function of the first drainage groove 113 is not affected.

[0078] The mounting base of the present application may be implemented as the mounting base shown in FIG. 11B. As shown in FIG. 11B, the same components of the mounting base 230 as those in FIG. 11A are designated by the same reference numerals, and their descriptions can be found in FIG. 11A without further explanation. The difference between FIG. 11B and FIG. 11A is that the mounting base in FIG. 11B further includes a flange 235 extending in the same direction as the clamping piece 232, one end connected to the main body 234, and the other end having a protrusion 235a extending toward the clamping piece 232. FIG. 10B is a schematic side view of connecting a photovoltaic profile to a roof using the mounting base in FIG. 11B. As shown in FIGS. 10B and 11B, the protrusion 235a of the flange 235 engages with the side surface 133c of the corner bracket mounting cavity 133. This enhances the stability of the connection between the third frame 130 and the roof.

[0079] 11B, in some embodiments, the mounting base 230 is provided on the main body 234 and further has a protrusion 236 that protrudes in the rear direction from the mounting edge 231. As shown in FIGS. 3C, 10B, and 11B, the protrusion 236 is crimped to the crimping edge 117 of the first frame 110, and the protrusion 236 applies pressure to the crimping edge 117 toward the third frame 130, which is advantageous in increasing the stability of the connection between the first frame 110 and the third frame 130.

[0080] The mounting base of the present application may be implemented as the mounting base shown in FIG. 11C. As shown in FIG. 11C, the difference between FIG. 11C and FIG. 11B is that the extending direction of the mounting edge 231 and the extending direction of the pressing edge 232 are the same. FIG. 10C is a side view showing a schematic diagram of connecting a photovoltaic profile and a roof using the mounting base of FIG. 11C. As shown in FIGS. 10C and 11C, the mounting edge 231 is attached to the roof 40.

[0081] As shown in FIG. 10A, in one embodiment, the photovoltaic mold further includes a waterproof seal 240 disposed between the first double plate 116 and the second double plate 136, as shown in FIG. 3B, to help prevent rainwater from penetrating into the photovoltaic mold through the gap between the first double plate 116 and the second double plate 136.

[0082] Continuing with FIG. 10A , in one embodiment, the photovoltaic roof mounting system further includes a watertight seal strip 170. As shown in FIG. 5D , the watertight seal strip 170 is provided in the notch 137a of the third frame 130. One end of the watertight seal strip 170 contacts the light-receiving surface of the photovoltaic module 221, which can further prevent rainwater from penetrating into the photovoltaic roof mounting system through the gap between the first double plate 116 and the second double plate 136. The photovoltaic roof mounting system in the above embodiment of the present application has the technical effects of being simple in structure and capable of efficiently draining rainwater.
