Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and more specifically, to a quick-installation photovoltaic roof water guiding structure and a building photovoltaic integrated system. Background Technology

[0002] Building-integrated photovoltaic (BIPV) systems integrate photovoltaic modules into the building envelope (such as the roof), giving it both power generation capabilities and building material properties.

[0003] However, current BIPV (Building Integrated Photovoltaic) systems typically rely on complex steel structures to support the photovoltaic modules. The installation of these complex steel structures requires various components such as purlins, main water channels, secondary water channels, waterproofing strips, ridge caps, support plates, pressure blocks, and pressure block fixing bolts. This type of photovoltaic roof structure has the following drawbacks:

[0004] (1) A large number of scattered components need to be assembled and fixed on site. The installation process is complicated, resulting in a long construction period and low efficiency.

[0005] (2) High material and construction costs.

[0006] (3) It is only applicable to specific types of roofs (such as roofs with a specific slope), and has poor versatility.

[0007] Therefore, how to provide a photovoltaic roof structure for a BIPV system that is simple in structure, easy to install, and highly versatile is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0008] In view of this, the purpose of this utility model is to provide a quick-installation photovoltaic roof drainage structure that can reduce the number of components, achieve rapid installation, and adapt to different roof slopes.

[0009] Another objective of this invention is to provide a building photovoltaic integrated system that includes the aforementioned quick-installation photovoltaic roof water guiding structure.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A quick-installation photovoltaic roof drainage structure for installing photovoltaic modules on a sloping roof, comprising:

[0012] Multiple frames, wherein a first side of the frame is provided with a mounting groove, and a second side of the frame opposite to the first side is provided with a first snap-fit ​​portion;

[0013] Multiple fasteners are used to fix the frame to the sloping roof. Each fastener includes a base and a second and a third latching portion, both of which are provided on the base. The third latching portion is set higher than the second latching portion, and both are latched and adapted to the first latching portion of the frame.

[0014] Among them, multiple rows of the fixing buckles are distributed along the slope direction of the sloping roof, and in each row of the fixing buckles, the third snap-fit ​​portion is closer to the high side of the sloping roof than the second snap-fit ​​portion;

[0015] The third snap-fit ​​portion snaps into the first snap-fit ​​portion of one of the frames, and the mounting groove of one of the frames is used to support the lower side edge of a photovoltaic module. The second snap-fit ​​portion snaps into the first snap-fit ​​portion of another frame, and the mounting groove of the other frame is used to support the higher side edge of another photovoltaic module.

[0016] Preferably, an upper groove is also provided on the second side of the frame;

[0017] The structure also includes a first arc-shaped guide vane, which is used to span the ridge of the sloping roof and is inserted between the upper slots of two adjacent frame sides, and the first arc-shaped guide vane protrudes away from the ridge.

[0018] Preferably, a lower groove is also provided on the second side of the frame;

[0019] The structure also includes a plurality of second arc-shaped guide vanes. In each pair of adjacent photovoltaic modules, a second arc-shaped guide vane is inserted between the two opposing frames, and the second arc-shaped guide vane protrudes downward.

[0020] Preferably, the frame includes a support, a side plate vertically disposed on one side of the top of the support, and a top plate extending from the top of the side plate. The top of the support, the side plate, and the top plate form the mounting groove, and the first snap-fit ​​portion is provided on the side of the support facing away from the opening of the mounting groove.

[0021] Preferably, the support is an inverted plate, the opening direction of the inverted plate is opposite to the groove direction of the mounting groove, and the first snap-fit ​​part is a snap-fit ​​strip formed by the bottom of the inverted plate protruding upwards near its opening side.

[0022] Preferably, the side plate has an upper groove and a lower groove on the side facing away from the mounting groove opening, from top to bottom.

[0023] Preferably, the base includes a first L-shaped plate and a second L-shaped plate, wherein the horizontal plate of the first L-shaped plate is disposed at the top of the vertical plate of the second L-shaped plate;

[0024] The third snap-fit ​​part is provided on the side of the vertical plate of the first L-shaped plate facing the high side of the sloping roof;

[0025] The second L-shaped plate has a second snap-fit ​​part on the side of the vertical plate facing the lower side of the sloping roof;

[0026] The second L-shaped plate has mounting holes on its horizontal plate for the fastener to pass through and fix the fastener to the sloping roof.

[0027] Preferably, the second snap-fit ​​portion and / or the third snap-fit ​​portion is a slot formed by two spaced and parallel protrusions.

[0028] Preferably, the horizontal plate of the first L-shaped plate is rotatably connected to the top of the vertical plate of the second L-shaped plate.

[0029] A building-integrated photovoltaic (BIPV) system, comprising:

[0030] Sloping roof;

[0031] The quick-installation photovoltaic roof drainage structure as described in any of the above claims is provided on the sloping roof;

[0032] Photovoltaic modules are installed on the quick-install photovoltaic roof water-guiding structure.

[0033] This utility model provides a quick-installation photovoltaic roof drainage structure. During on-site installation, multiple rows of fixing buckles are arranged along the slope of the sloping roof. Because each fixing buckle has a second locking part and a third locking part positioned higher than the second locking part, the higher third locking part is closer to the higher side of the sloping roof than the lower second locking part. In each row of fixing buckles, the third locking part engages with the first locking part of a frame, whose mounting groove supports the lower edge of a photovoltaic module. The second locking part engages with the first locking part of another frame, whose mounting groove supports the higher edge of another photovoltaic module. In other words, the frame of one photovoltaic module near the lower side of the sloping roof and the frame of the next photovoltaic module near the higher side of the sloping roof are stacked vertically on the same fixing buckle, allowing adjacent photovoltaic modules to be laid along the sloping roof in a stacked manner, thus completing the photovoltaic roof installation.

[0034] As can be seen from the above description, the quick-installation photovoltaic roof drainage structure of this application has the following beneficial effects:

[0035] (1) The fixed buckle is plugged into the frame for installation, which does not require complicated tools or a large number of fasteners. The installation process is simple, the construction cycle is shortened, and the installation efficiency is high.

[0036] (2) It eliminates the need for complex components such as purlins, special pressure blocks, and a large number of bolts required for the original complex steel structure installation, thus reducing material and construction costs.

[0037] (3) Photovoltaic modules can be laid on the sloping roof in a stacked manner to adapt to the slope of the sloping roof. By adjusting the spacing of the fixing buckles in different columns, they can adapt to different slopes of the sloping roof, making them highly versatile.

[0038] (4) This structure is an independent installation structure that does not depend on the specific structure of the roof itself (such as the wave height of the corrugated steel tile). It can be widely applied to various types of sloping roofs such as corrugated steel tile roofs, tile roofs, concrete roofs, and sunrooms, and has strong versatility. Attached Figure Description

[0054] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0055] The core of this utility model is to provide a quick-installation photovoltaic roof water guiding structure, which can reduce the number of components, achieve rapid installation, and adapt to different roof slopes.

[0056] Another core aspect of this invention is to provide a building-integrated photovoltaic system that includes the aforementioned quick-installation photovoltaic roof water-guiding structure.

[0057] It should be noted that in this embodiment, the orientation or positional relationship indicated by "upper" and "lower" is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the purpose of facilitating the description of this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.

[0058] Please refer to Figure 1 , Figure 2 and Figure 3 This application provides a specific embodiment of a quick-install photovoltaic roof drainage structure for installing photovoltaic modules 2 on a sloping roof 1, including multiple frame frames 3 and multiple fixing buckles 4.

[0059] The first side of the frame 3 is provided with a mounting groove 34 for installing the photovoltaic module 2, and the second side of the frame 3 opposite to the first side is provided with a first snap-fit ​​part 35.

[0060] The fixing buckle 4 is used to fix the frame 3 to the sloping roof 1. The fixing buckle 4 includes a base 41, and a second snap-fit ​​part 42 and a third snap-fit ​​part 43 both provided on the base 41. The third snap-fit ​​part 43 is set higher than the second snap-fit ​​part 42, and both are snap-fitted and adapted to the first snap-fit ​​part 35 of the frame 3.

[0061] Among them, multiple rows of fixing buckles 4 are distributed along the slope direction of the sloping roof 1. In each row of fixing buckles 4, the third snap-fit ​​part 43 is closer to the high side of the sloping roof 1 than the second snap-fit ​​part 42. The third snap-fit ​​part 43 snaps into the first snap-fit ​​part 35 of a frame 3. The mounting groove 34 of the frame 3 is used to support the low side edge of a photovoltaic module 2. The second snap-fit ​​part 42 snaps into the first snap-fit ​​part 35 of another frame 3. The mounting groove 34 of the other frame 3 is used to support the high side edge of another photovoltaic module 2.

[0062] It should be noted that the photovoltaic module 2 is usually equipped with a frame 3 around its perimeter to protect the internal structure of the module and improve its mechanical strength.

[0063] Specifically, the frame 3 can be made of lightweight, corrosion-resistant, and high-strength long strip aluminum alloy profile. The first side of the frame 3 in the thickness direction is provided with a mounting groove 34, and either the long or short side of the photovoltaic module 2 can be inserted into the mounting groove 34. The second side of the frame 3 in the thickness direction is provided with a first snap-fit ​​part 35.

[0064] The fixing buckle 4 includes a base 41, on which a second snap-fit ​​part 42 and a third snap-fit ​​part 43 are provided. The third snap-fit ​​part 43 is positioned higher than the second snap-fit ​​part 42, and both the second snap-fit ​​part 42 and the third snap-fit ​​part 43 are snap-fitted and adapted to the first snap-fit ​​part 35.

[0065] In the above embodiment, during on-site installation, multiple fixing buckles 4 are distributed along the slope direction of the sloping roof 1 (i.e., from the ridge to the eaves) to form multiple rows of fixing buckles 4. Since the third locking part 43 is higher than the second locking part 42, when the fixing buckles 4 are installed on the sloping roof 1, the higher third locking part 43 is closer to the high side (ridge direction) of the sloping roof 1 than the lower second locking part 42, thus completing the arrangement of the fixing buckles 4. Then, in each row of fixing buckles 4, the first locking part 35 of one frame 3 is inserted into the third locking part 43 of the fixing buckle 4. At this time, the mounting groove 34 of the frame 3 can support the lower long side of the upper photovoltaic module 2. The first locking part 35 of another frame 3 is inserted into the second locking part 42 of the fixing buckle 4. At this time, the mounting groove 34 of the frame 3 can support the higher long side of the lower photovoltaic module 2. Repeating this step can quickly complete the installation of multiple rows of photovoltaic modules 2.

[0066] The above embodiments have the following effects:

[0067] First, the plug-in installation between the fixing buckle 4 and the frame 3 eliminates the need for complex tools or a large number of fasteners, making the installation process simple, shortening the construction cycle, and increasing installation efficiency.

[0068] Secondly, it eliminates the need for complex components such as purlins, special clamps, and a large number of bolts required for the original complex steel structure installation, thus reducing material and construction costs.

[0069] Third, the fixing buckle 4 is provided with a second locking part 42 and a third locking part 43 with different heights, which can enable the photovoltaic module 2 to be laid along the sloping roof 1 in a stacked manner to adapt to the slope of the sloping roof 1. Furthermore, by adjusting the spacing of different columns of fixing buckles 4, it can adapt to different slopes of the sloping roof 1, making it highly versatile.

[0070] Fourth, this structure is an independent installation structure that does not depend on the specific structure of the roof itself (such as the wave height of the corrugated steel sheet). It can be widely applied to various types of sloping roofs, such as corrugated steel sheet roofs, tile roofs, concrete roofs, and sunrooms, making it highly versatile.

[0071] Based on the above embodiments, as a further preferred embodiment, the multi-row fixing buckle 4 includes multiple fixing buckles 4, which are spaced apart along the slope direction perpendicular to the sloping roof 1. In this way, the frame 3 of the photovoltaic module 2 can have multiple engagement points with a row of fixing buckles 4, thereby providing more stable support for the photovoltaic module 2 and giving the entire system good structural strength and stability.

[0072] Based on the above embodiments, as a further preferred option, please refer to... Figure 1 , Figure 4 , Figure 7 and Figure 8 The second side of the frame 3 is also provided with an upper slot 36; the first arc-shaped guide plate 5 is used to span the ridge of the sloping roof 1 and is inserted between the upper slots 36 of two adjacent frames 3, and the first arc-shaped guide plate 5 protrudes away from the ridge.

[0073] It should be noted that the ridge of the sloping roof 1 refers to the highest point of the two slopes, and the frames 3 of the adjacent photovoltaic modules 2 located on both sides of the ridge are arranged in a V-shape facing each other. The second side of the frame 3 (the side facing away from the mounting groove 34 and the photovoltaic module 2) has a pre-processed upper groove 36.

[0074] During installation, the first arc-shaped guide plate 5 is placed across the roof ridge, with its two side edges inserted into the upper slots 36 of the two adjacent side frames 3, respectively. The first arc-shaped guide plate 5 protrudes away from the roof ridge to cover it. In this way, when rainwater flows from above to the roof ridge, the first arc-shaped guide plate 5 can divert the rainwater to both sides, preventing rainwater from seeping into the roof interior through the gaps between the photovoltaic modules 2.

[0075] More preferably, both sides of the first arc-shaped guide vane 5 are provided with arc-shaped wings. The arc-shaped wings are components made of elastic material, which makes it easy for the arc-shaped wings to be inserted into the upper slot 36 and to be tightly fastened to the upper slot 36, thereby achieving a firm installation without any additional fasteners or adhesives, making the installation convenient and efficient.

[0076] Based on the above embodiments, as a further preferred option, please refer to... Figure 1 , Figure 4 , Figure 9 and Figure 10 The second side of the frame 3 is also provided with a lower slot 37; the structure also includes a plurality of second arc-shaped guide plates 6, in which a second arc-shaped guide plate 6 is inserted between two opposing frames 3 in each of two adjacent photovoltaic modules 2, and the second arc-shaped guide plate 6 protrudes downward.

[0077] It should be noted that multiple photovoltaic modules 2 are distributed along the slope direction of the sloping roof 1 via frame 3 and fixing buckle 4. A seam is formed between each two adjacent photovoltaic modules 2 (along the slope direction perpendicular to the sloping roof 1). It is easy to see that this seam is formed by two opposing frame 3. The second side of the frame 3 (i.e. the side facing away from the mounting groove 34 and photovoltaic module 2) has a pre-processed lower groove 37.

[0078] During installation, the second arc-shaped guide plate 6 is placed below the joint between two adjacent photovoltaic modules 2, with its two side edges inserted into the lower slots 37 of the two adjacent frame 3s on the left and right sides, respectively. The second arc-shaped guide plate 6 protrudes downwards, forming a guide channel located below the joint. In this way, when rainwater seeps into the joint along the surface of the photovoltaic module 2, the guide channel can collect and guide the rainwater out of the joint, preventing rainwater from seeping into the roof from the gaps between the photovoltaic modules 2.

[0079] More preferably, both sides of the second arc-shaped guide vane 6 are also provided with arc-shaped wings. The arc-shaped wings are components made of elastic material, which makes it easy for the arc-shaped wings to be inserted into the lower slot 37 and to be tightly fastened to the lower slot 37, thereby achieving a firm installation without any additional fasteners or adhesives, making the installation convenient and efficient.

[0080] Based on the above embodiments, as a further preferred option, please refer to... Figure 4 The frame 3 includes a support 31, a side plate 32 vertically disposed on one side of the top of the support 31, and a top plate 33 extending from the top of the side plate 32. The top of the support 31, the side plate 32 and the top plate 33 form a mounting groove 34. A first snap-fit ​​part 35 is provided on the side of the support 31 facing away from the opening of the mounting groove 34.

[0081] Specifically, the support 31 serves as the base of the entire frame 3, used to fix it to the sloping roof 1. The side plate 32 is vertically set on one side edge of the support 31, and the top of the side plate 32 extends horizontally to the other side of the support 31 to form a top plate 33. In this way, the top of the support 31, the side plate 32, and the top plate 33 can form a mounting groove 34. The cross-section of this mounting groove 34 is U-shaped, which can effectively wrap and clamp the edge of the photovoltaic module 2, thereby improving the structural stability of the photovoltaic module 2 and effectively preventing the module from deforming or shaking.

[0082] In addition, the support 31 is provided with a first snap-fit ​​part 35. Since the first snap-fit ​​part 35 is engaged with the corresponding snap-fit ​​part on the fixing buckle 4, and the photovoltaic module 2 is inserted into the slot of the mounting groove 34, the first snap-fit ​​part 35 is located on the side facing away from the slot of the mounting groove 34, so as to avoid the photovoltaic module 2 interfering with the frame 3 being inserted into the fixing buckle 4.

[0083] Based on the above embodiments, as a further preferred option, please refer to... Figure 4 The support 31 is an inverted plate, the opening direction of which is opposite to the groove direction of the mounting groove 34. The first snap-fit ​​part 35 is a snap-fit ​​strip formed by the bottom of the inverted plate protruding upwards near its opening side.

[0084] Specifically, the support 31 is an inverted L-shaped plate, which provides a stable base for the photovoltaic module 2, preventing deformation and swaying, while also reducing weight and material costs. The inverted L-shaped plate consists of symmetrical upper and lower plates, and a straight plate connecting the upper and lower plates on the same side. The side plate 32 and the top plate 33 are vertically connected to form an inverted L-shaped plate. The bottom end of the inverted L-shaped plate is located on the side of the upper plate away from the straight plate, forming a mounting groove 34 with the upper plate. Thus, the opening direction of the inverted L-shaped plate is opposite to the groove direction of the mounting groove 34. During installation, the opening of the inverted L-shaped plate is fitted with a fixing buckle 4, and the groove of the mounting groove 34 is fitted with the photovoltaic module 2. Since they face opposite directions, structural interference between the photovoltaic module 2 and the fixing buckle 4 can be avoided.

[0085] In addition, the bottom of the C-shaped plate near its opening side protrudes upward to form a retaining strip extending along the length of the frame 3. This retaining strip is integrally formed with the support 31, avoiding additional connecting parts, reducing processing costs, and ensuring a stable and reliable connection between the frame 3 and the fixing seat. It should be noted that the second or third engaging part 43 on the fixing buckle 4 can preferably be a slot adapted to engage with the retaining strip.

[0086] Based on the above embodiments, as a further preferred option, please refer to... Figure 4 The side plate 32 has an upper slot 36 and a lower slot 37 on the side facing away from the mounting groove 34 from top to bottom.

[0087] Specifically, the support 31 is installed on the sloping roof 1 by the fixing buckle 4. One side of the side plate 32 faces and is in close contact with the photovoltaic module 2. Only the other side of the side plate 32 (i.e. the side facing away from the groove of the mounting groove 34) is not blocked by the module. The side plate 32 is provided with an upper groove 36 and a lower groove 37 from top to bottom. Both grooves extend along the length of the side plate 32 to penetrate the entire frame 3.

[0088] The upper slot 36 is positioned high and can support the first arc-shaped guide plate 5 that spans the roof ridge, guiding rainwater to flow from high to low along the slope of the roof. The lower slot 37 is positioned low and can support the second arc-shaped guide plate 6, placing it below the joint between two adjacent photovoltaic modules 2, guiding rainwater to drain from the joint along the slope perpendicular to the roof.

[0089] Based on the above embodiments, as a further preferred option, please refer to... Figure 5 The base 41 includes a first L-shaped plate 411 and a second L-shaped plate 412. The horizontal plate of the first L-shaped plate 411 is located at the top of the vertical plate of the second L-shaped plate 412. The side of the vertical plate of the first L-shaped plate 411 facing the high side of the sloping roof 1 is provided with a third snap-fit ​​part 43. The side of the vertical plate of the second L-shaped plate 412 facing the low side of the sloping roof 1 is provided with a second snap-fit ​​part 42. The horizontal plate of the second L-shaped plate 412 is provided with a mounting hole 44 for the fastener 7 to pass through and for the fastener 4 to be fixed to the sloping roof 1.

[0090] Specifically, the horizontal plate of the first L-shaped plate 411 is fixed to the top of the second L-shaped plate 412, and the two have a certain angle, so that the vertical plate of the first L-shaped plate 411 is suspended in front of the vertical plate of the second L-shaped plate 412, that is, the vertical plate of the first L-shaped plate 411 is closer to the high side (ridge) of the sloping roof 1 than the vertical plate of the second L-shaped plate 412. Among them, the side of the vertical plate of the first L-shaped plate 411 facing the ridge is provided with a third locking part 43 (positioned higher), and the side of the vertical plate of the second L-shaped plate 412 facing the eaves is provided with a second locking part 42 (positioned lower).

[0091] During installation, the higher third snap-fit ​​part 43 snaps into the bottom of the frame 3 of the upper photovoltaic module 2, and the lower second snap-fit ​​part 42 snaps into the bottom of the frame 3 of the lower photovoltaic module 2, thereby achieving the stacking and fixing of the upper and lower photovoltaic modules 2.

[0092] In this embodiment, by setting the second snap-fit ​​part 42 and the third snap-fit ​​part 43 on two L-shaped vertical plates at different heights, a height difference is formed and the structure is stable, ensuring that the frame 3 of the upper and lower photovoltaic modules 2 can be fixed at a suitable height, so as to realize the stable installation of the photovoltaic modules 2 along the slope direction of the sloping roof 1.

[0093] In addition, the mounting hole 44 is located on the horizontal plate of the second L-shaped plate 412, which provides ample operating space for the installation of the fastener 7 (such as screws or bolts), making it convenient to install the fastener 7. Moreover, the two snap-fit ​​parts face different directions, which provides ample operating space for the snap-fit ​​of the frame 3 and the snap-fit ​​strip, reducing the difficulty of installation.

[0094] Based on the above embodiments, as a further preferred option, please refer to... Figure 5 The second latching portion 42 and / or the third latching portion 43 are latching grooves formed by two spaced and parallel protrusions.

[0095] Specifically, the vertical plate of the first L-shaped plate 411 has two spaced and parallel protruding plates on the side facing the roof ridge. The protruding plates extend along the length of the vertical plate, and the two protruding plates and the vertical plate form a slot. Similarly, the vertical plate of the second L-shaped plate 412 can also form a slot on the side facing the eaves according to the above structure. This slot structure provides a guide channel for the first snap-fit ​​part 35 (i.e., the snap-fit ​​strip) of the frame 3. During installation, the snap-fit ​​strip of the frame 3 can be easily inserted or slid into this slot, simplifying the installation operation and improving installation efficiency.

[0096] Based on the above embodiments, as a further preferred embodiment, the horizontal plate of the first L-shaped plate 411 is rotatably connected to the top of the vertical plate of the second L-shaped plate 412. Thus, the second L-shaped plate 412 is fixed to the sloping roof 1 by the fastener 7, remaining stationary, while the first L-shaped plate 411 can rotate relative to the second L-shaped plate 412, allowing for angle adjustment. This enables the fixing buckle 4 to better adapt to different roof slopes, while also increasing the contact area between the horizontal plate of the fixing buckle 4 and the bottom of the photovoltaic module 2 frame 3, making the installation of the photovoltaic module 2 more stable and reliable.

[0097] In one specific embodiment, the top of the vertical plate of the second L-shaped plate 412 is provided with a hinge seat having a shaft hole, and the horizontal plate of the first L-shaped plate 411 is provided with a shaft hole coaxial with the shaft hole. The pin passes through the two shaft holes to realize the rotational connection between the horizontal plate of the first L-shaped plate 411 and the top of the second L-shaped plate 412.

[0098] During installation, the second L-shaped plate 412 of the fixing buckle 4 is firmly fixed to the roof through the mounting holes 44 on its horizontal plate, while the first L-shaped plate 411 above can rotate around the pin at a certain angle. When the frame 3 of the photovoltaic module 2 is snapped into the third snap-fit ​​part 43 on the vertical plate of the first L-shaped plate 411, the first L-shaped plate 411 will automatically rotate slightly under the weight of the module until its horizontal plate is in contact with the bottom of the frame 3 of the photovoltaic module 2, thereby achieving adaptive fitting of the fixing buckle 4 to the frame 3 and different roof slopes.

[0099] This utility model also provides a building-integrated photovoltaic system, including a sloping roof 1, the quick-install photovoltaic roof water guiding structure disclosed in the above embodiments, and photovoltaic modules 2.

[0100] When installing photovoltaic modules 2 on the sloping roof 1 of the building, multiple fixing buckles 4 of the quick-install photovoltaic roof water guiding structure are fixed to the roof with fasteners 7 (such as self-tapping screws). Then, the edges of the photovoltaic modules 2 are embedded into the mounting grooves 34 of the frame 3, and quickly snapped together with the first snap-fit ​​part 35 at the bottom of the frame 3 and the second and third snap-fit ​​parts on the fixing buckles 4, which are staggered at different heights. All photovoltaic modules 2 are laid up and down along the roof slope. Subsequently, at the ridge, the two sides of the upward-protruding first arc-shaped guide plate 5 are inserted into the upper grooves 36 of the adjacent frame 3. At the joint between two adjacent photovoltaic modules 2, the two sides of the downward-protruding second arc-shaped guide plate 6 are inserted into the lower grooves 37 of the two opposing frame 3. Thus, the photovoltaic modules 2, the photovoltaic roof water guiding structure and the sloping roof 1 constitute a building roof that integrates power generation and water guiding.
