Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic integration, and in particular to an assembled photovoltaic integration module and a photovoltaic system. Background Art

[0002] Steel structure buildings are mainly used in industrial plants, stadiums and transportation facilities, such as airports and high-speed railways. They are generally single-story buildings with large land area, large span and large single-building area. Now, new construction, expansion and reconstruction of buildings and energy-saving renovation of existing buildings require building energy-saving design, which means that photovoltaic power generation systems need to be installed on the roofs of steel structure buildings. However, adding a photovoltaic power generation system to the roof requires an increase in the constant load, and increasing the constant load requires an increase in the overall steel usage of the steel structure building, which is contrary to the demand for building energy conservation. Therefore, it is necessary to ensure that the roof can bear the photovoltaic components without additionally modifying the roof.

[0003] Currently, photovoltaic modules are generally fixed to the crests of the color steel tiles on the roof by metal clamps through bolts, metal purlins are fixed on the metal clamps, and then the photovoltaic modules are fixed and locked by metal pressing blocks and bolts to achieve the fixation of photovoltaic modules on the color steel tiles. However, with this installation method, the fixed connection between the metal clamp and the crest of the color steel tiles on the roof is easily deformed by wind. And the metal clamp and the crest of the color steel tiles will produce a friction effect, resulting in damage to the waterproof and anti-corrosion coating of the crest of the color steel tiles. However, the service life of ordinary color steel tile roofs does not match that of photovoltaic modules. How to extend the service life of the color steel tile roofs of existing steel structure buildings, reduce the risk of replacing tiles and disassembling photovoltaic modules, and ensure their coexistence.

[0004] In addition, the photovoltaic panels arranged in this way have poor pressure resistance and are easily broken under external forces such as hail. When assembling photovoltaic panels, it is inevitable that construction workers need to walk on the photovoltaic panels to install them. In order to improve efficiency, there are also existing technologies that use modular design of photovoltaic modules and use automatic assembly equipment to walk on the photovoltaic panels to install and assemble photovoltaic modules.

[0005] The existing photovoltaic / solar thermal (PV / T) technology is an integrated product, which integrates photovoltaic power generation technology and collectors. It is mainly composed of photovoltaic modules and heat exchangers, and can generate electricity and heat energy at the same time. Since the efficiency of photovoltaic modules will decrease as the battery temperature increases, the photovoltaic modules are cooled by circulating fluid in the collector to reduce the loss of power generation efficiency, improve the utilization rate of solar energy, and better meet the requirements of building energy conservation. However, the integration of these two technologies increases the cost and limits the application scenarios. Therefore, a split-type composite system product design is needed to achieve a balance between cost reduction and energy saving, so as to meet the application needs in more scenarios and reduce the difficulty of market promotion and technology popularization. Summary of the invention

[0006] Based on this, the purpose of the present invention is to provide an assembled photovoltaic integrated module and photovoltaic system, aiming to solve the problem in the prior art of lacking an assembled photovoltaic integrated module product with light weight, strong pressure resistance, good waterproof performance, support plate and photovoltaic component with the same service life, high solar energy utilization rate and high assembly efficiency, so as to realize factory industrial prefabrication production and manufacturing, and reduce the problem of difficult quality control of on-site assembly and gluing.

[0007] According to an embodiment of the present invention, an assembled photovoltaic integrated module includes a photovoltaic component, a support plate arranged at the bottom of the photovoltaic component, a support connecting sleeve and a support seat arranged below the support plate, the support seat is used to connect with the roof tile steel purlin, the support plate is in a wavy shape of a figure "J", the support connecting sleeve is arranged at the bottom of the crest of the support plate, and is located between the support plate and the support seat for auxiliary support, the middle part of the crest of the support plate is recessed downward to form a glue-containing groove, so that the photovoltaic component and the support plate are fixedly connected by glue.

In addition, by providing a glue-containing groove, the photovoltaic module is connected to the support plate, and a support connection sleeve connected to the support plate is provided, and adjacent photovoltaic modules are connected to each other through the support connection sleeve, and then this connection and fixing method is adopted to avoid the friction and tearing effect of the clamp on the roof and the photovoltaic panel, and the service life of the photovoltaic module is improved. In addition, the support plate with a bent wave crest is used to support the photovoltaic module and connect to the roof, which is lighter than the horizontal whole plate and the need for additional clamps to fix. And semi-flexible crystalline silicon lightweight photovoltaic modules can be used to further reduce the weight of the photovoltaic module. In addition, by reasonably adjusting the position of the supporting connection sleeve, the connecting support sleeve and the support plate cooperate with each other, the mechanical structural strength of the longitudinal spacing is strengthened, the deformation of the photovoltaic integrated modular product when subjected to trampling pressure and hail impact pressure is reduced, and the hidden cracks of the crystalline silicon cells of the photovoltaic module are prevented. In addition, through the socket connection of the supporting connection sleeve and sufficient pressure resistance, automatic assembly equipment can be used to improve the assembly efficiency.

[0020] The following specific implementation manner will further illustrate the present invention in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0021] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0024] See also Figures 1 to 8 , which shows an assembled photovoltaic integrated module in an embodiment of the present invention, including a photovoltaic module 10, a support plate 20 arranged at the bottom of the photovoltaic module 10, a support connection sleeve 30 and a support seat 40 arranged below the support plate 20, wherein: The support seat 40 is used to connect with the steel purlins of the roof tiles. The support plate 20 is in a wavy shape. The connecting sleeve of the support plate 20 is set at the bottom of the crest of the support plate 20, and is located between the support plate 20 and the support seat 40 for auxiliary support. The middle part of the crest of the support plate 20 is recessed downward to form a glue groove 21, so that the photovoltaic module 10 and the support plate 20 are fixedly connected by glue, and the drying equipment is used to accelerate the curing.

[0025] It can be understood that by setting a wavy support plate 20 for supporting the photovoltaic module 10, the support plate can be made of a metal corrugated plate or other non-metallic composite materials, and the distance between adjacent wave peaks is adjusted so that the distance between adjacent wave peaks is less than the width of the construction personnel's foot or less than the width of the construction equipment's driving wheel, so as to ensure that the support plate 20 provides sufficient support force to improve the compression resistance of the photovoltaic panel and avoid the photovoltaic panel from breaking. In addition, by setting a glue-containing groove 21, the photovoltaic module 10 is connected to the support plate 20, and a support connection sleeve 30 connected to the support plate 20 is set, and adjacent photovoltaic modules are connected to each other through the support connection sleeve 30, and then this connection and fixing method is adopted to avoid the friction and tearing effect of the clamp on the roof and the photovoltaic panel, and the service life of the photovoltaic module 10 is improved. In addition, the bending wave-shaped support plate 20 is used to support the photovoltaic module 10 and is used to connect to the roof, which is lighter than the horizontal whole plate and the need for additional clamps. And semi-flexible crystalline silicon lightweight photovoltaic modules can be used to further reduce the weight of the photovoltaic module. In addition, by reasonably adjusting the position of the supporting connection sleeve 30, the connecting support sleeve and the support plate 20 cooperate with each other, thereby strengthening the mechanical structural strength of the longitudinal spacing, reducing the deformation of the photovoltaic integrated modular product when subjected to trampling pressure and hail impact pressure, and preventing the hidden cracks of the crystalline silicon cells of the photovoltaic module 10. In addition, through the socket connection of the supporting connection sleeve 30 and sufficient pressure resistance, automatic assembly equipment can be used to improve the assembly efficiency. Therefore, the present invention solves the problem in the prior art of lacking an assembled photovoltaic integrated module with light weight, strong pressure resistance, high service life and assembly efficiency.

[0026] It should be noted that the existing technical solution for building photovoltaic integration using structural adhesive to glue photovoltaic modules 10 is to first press colored steel tiles at the project construction site using a high-altitude tile press, and then fix the photovoltaic modules 10 on the colored steel tiles with structural adhesive. The gluing process is greatly affected by external environmental factors (temperature, humidity). It generally takes 24-72 hours for the structural adhesive to dry and cure to reach the standard bonding strength, and there is a 14-21 day curing and curing time. Under low temperature and low humidity, the curing speed of the structural adhesive will be slower, and the curing period after gluing will be longer in winter. In order to ensure the bonding performance, it is even necessary to place heavy objects on the photovoltaic modules 10. During this period, the photovoltaic modules 10 are prone to displacement, loosening and false adhesion, and the construction quality is difficult to control. In the photovoltaic integrated module of the present application, the support plate 20, the photovoltaic component 10 and the support connecting sleeve 30 are all assembled and connected, and then transported to the construction unit as independent individual parts for construction. That is, the step of fixing the photovoltaic component 10, the support connecting sleeve 30 and the support plate 20 with structural adhesive has been completed in the dust-free workshop of the factory. Therefore, the present application eliminates the problems existing in the on-site construction of the above-mentioned structural adhesive.

[0027] In addition, an auxiliary tube 50 is provided at one end of the support and connection sleeve 30, and the outer contour size of the auxiliary tube 50 is smaller than the inner contour size of the support and connection sleeve 30. A card slot 51 is provided on both sides of the auxiliary tube 50, and a through slot 31 adapted to the card slot 51 is provided at the other end of the support and connection sleeve 30. A card block 32 inclined toward the inner side of the support and connection sleeve 30 is provided in the through slot 31, and the card block 32 cooperates with the card slot 51 to connect the assembled photovoltaic integrated modules adjacent to each other in the length direction of the support and connection sleeve 30. In the specific implementation, the support and connection sleeve 30 and the support plate 20 are connected by welding, gluing or mechanical metal kit, and the support and connection sleeve 30 can be formed of metal material or non-metal material. By providing the auxiliary tube 50, the card slot 51 and the card block 32, the adjacent assembled photovoltaic integrated modules can be connected by sleeve-mounting the end of the support and connection sleeve 30 without the auxiliary tube 50 on the auxiliary tube 50, and the card block 32 is embedded in the card slot 51, so as to realize the rapid assembly connection between the adjacent assembled photovoltaic integrated modules. In addition, the two sides of the slot 51 of the auxiliary tube 50 can also be provided with a glue groove 21, so that the two supporting connecting sleeves 30 are not only connected by the concave and convex mortise and tenon joints, but also strengthened and fixed by structural glue to enhance the connection strength. In addition, the length of the supporting connecting sleeve 30 is equal to the spacing between the two purlins and the truss support system of the roof. It is erected on the roof purlin or truss support system. The combination of the supporting connecting sleeve 30 and the supporting corrugated metal plate strengthens the mechanical structural strength of the longitudinal spacing, reduces the deformation of the photovoltaic integrated modular product when subjected to trampling pressure and hail impact pressure, and prevents the hidden cracking of the crystalline silicon cell of the photovoltaic module 10. The number of supporting connecting sleeves 30 installed at the bottom of the supporting corrugated metal plate crest can be increased or decreased according to the actual needs of the structural strength. By installing the structural combination of the supporting connecting sleeve 30 at the bottom of the supporting corrugated metal plate crest, the material optimization of the thickness of the supporting corrugated metal plate and the thickness of the supporting connecting sleeve 30 is achieved, thereby reducing the amount of steel or non-metallic supporting plate materials, and achieving the purpose of energy saving and consumption reduction in buildings.

[0028] Specifically, multiple support connection sleeves 30 are evenly distributed at the bottom of the crest of the support plate 20, and the sizes of each support connection sleeve 30 are consistent. The lengths of the multiple support connection sleeves 30 extending out of one side of the photovoltaic module 10 are inconsistent. By way of example and not limitation, in some optional embodiments, the sizes of the support connection sleeves 30 are consistent, and the lengths of the adjacent support connection sleeves 30 extending out of the photovoltaic module 10 on the same side are different, so that the contact points between the adjacent support connection sleeves 30 and the auxiliary tube 50 are not on the same plane, thereby preventing stress concentration and enhancing the overall compression, tension and shear resistance of the device.

[0029] For example and not limitation, see Figures 10 to 12 as well as Fig.15 and Fig.16As shown, in some optional embodiments, a first clamping member 24 and a second clamping member 25 are respectively provided at both ends of the support plate 20 to match each other. The first clamping member 24 includes a cylindrical portion 241 provided on the support plate 20 and a flange portion 242 provided on the top of the cylindrical portion 241, and the second clamping member 25 includes a fixed flange 251 provided on the support plate 20 and a spring clamp 252 provided in the fixed flange 251, and the spring clamp 252 is adapted to the cylindrical portion 241 and fixed by a rivet 26, so that the support plates 20 on both sides are fixedly connected. In addition, the tightness of the connection between each support plate 20 is further enhanced, so that the integrity of the multiple assembled photovoltaic integrated modules is high, so that when subjected to a large range of forces, the multiple assembled photovoltaic integrated modules can quickly and evenly distribute the forces as a whole, thereby enhancing the wind resistance, and there will be no situation of local concentrated force damage. In addition, a buckle 27 is also provided on the cylindrical portion 241, so as to enhance the tightness of the connection between the spring clip 252 and the flange portion 242 through the buckle 27, thereby further enhancing the connection strength between adjacent support plates 20. In addition, in a specific implementation, the cylindrical portion 241, the flange portion 242 and the fixed flange 251 can be formed by punching and turning outward of the support plate 20 locally, and then the first clamping member 24 and the second clamping member 25 are formed by using the existing spring clip 252, the buckle 27 and the rivet 26. The difficulty of the preparation process of the first clamping member 24 and the second clamping member 25 is reduced, and compared with only setting two connection holes connected by rivets 26, the flange portion 242, the fixed flange 251, the buckle 27 and the spring clip 252 are additionally provided, so that the clamping connection is locally strengthened, thereby avoiding the local force concentration at the clamping connection, and then deformation and damage. After adopting this connection method, the connection between the photovoltaic modules 10 is tighter and the spacing is smaller. Then, a stepped waterproof board 28 can be set below the two sides of the photovoltaic module 10, so that after the two support boards 20 are overlapped and connected with each other, the two waterproof boards 28 will also overlap with each other, so that the waterproof board 28 can replace the breathable waterproof component 80, further reducing the overall weight and cost of the photovoltaic module. In addition, when adopting this connection method, the rivets 26 can be directly connected to the roof tile steel purlin, thereby reducing the support seat 40, thereby further reducing the overall weight of the photovoltaic module, achieving the reduction of the new load of the building and reducing the cost.

[0030] In addition, the supporting plate 20 is provided with a first connector 22 and a second connector 23 that cooperate with each other on both sides, the first connector 22 includes a first horizontal portion 221, a first L-shaped portion 222 vertically connected to one end of the first horizontal portion 221, and a vertical portion 223 vertically connected to the other end of the first L-shaped portion 222, the second connector 23 includes a second horizontal portion 231, a second L-shaped portion 232 vertically connected to the other end of the second horizontal portion 231, and a third L-shaped portion 233 vertically connected to the other end of the second L-shaped portion 232, and the second connector 23 is sleeved on the first connector 22 so that the second L-shaped portion 232 and the third L-shaped portion 233 are respectively abutted against the first L-shaped portion 222 and the vertical portion 223. In a specific implementation, the second connector 23 is sleeved on the first connector 22 so that two adjacent assembled photovoltaic integrated modules can be quickly assembled and connected, and the first connector 22 and the second connector 23 interact with each other to at least limit the movement of the assembled photovoltaic integrated module in the left and right directions. In addition, by way of example and not limitation, in some optional embodiments, the lateral section of the third L-shaped portion 233 can be bent toward the vertical portion 223, thereby enabling interaction between the first connector 22 and the second connector 23. This can also limit the movement of the assembled photovoltaic integrated modules in the up and down directions, thereby only retaining the degrees of freedom in the front and back directions for assembly, further improving the connection strength between the assembled photovoltaic integrated modules, and making the multiple assembled photovoltaic integrated modules highly integrated. When subjected to a larger range of forces, such as a large area of ​​wind of a certain intensity, the multiple assembled photovoltaic integrated modules can quickly and evenly share the forces as a whole, thereby enhancing the wind resistance and preventing local concentrated force damage.

[0031] It should be noted that, by way of example and not limitation, in some optional embodiments, the support plate 20 is formed by integrally pressing a metal plate, and the size of the metal plate is usually fixed. After the metal plate is pressed into a wavy shape, the width of the metal plate becomes smaller, that is, the size becomes smaller. In order to ensure that the size of the metal plate after the press is as large as possible to reduce the number of metal plates required, the number of wave peaks is usually as small as possible, that is, under the condition of ensuring the requirements, the spacing between the wave peaks will be as large as possible, which may lead to the situation that the structural strength after the press may not meet the requirements. If the spacing is not adjusted properly, the size of the two sides of the corrugated metal plate will not be suitable for forming another wave peak. Therefore, by setting the support connecting sleeve 30, the support plate 20 is assisted to adjust the overall structure through multiple support connecting sleeves 30. The support connecting sleeve 30 can also be formed by integrally pressing a metal plate, and the size is adjustable. By adjusting the position and number of the support connecting sleeve 30, the structural strength of the metal plate and the support connecting sleeve 30 as a whole can be adjusted, and metal plates of different thicknesses can be used. In addition, the first connecting member 22 and the second connecting member 23 are also integrated with the support plate 20, and are both formed by pressing a metal plate. Since the first connecting member 22, the second connecting member 23 and the support plate 20 are arranged as one body, the structural strength between the first connecting member 22, the second connecting member 23 and the support plate 20 is further ensured.

[0032] Specifically, the first horizontal portion 221 and the second horizontal portion 231 constitute the trough of the support plate 20, and the length of the first horizontal portion 221 is greater than the second horizontal portion 231, so that the position where the first connector 22 and the second connector 23 are fixed together is offset from the midpoint of the trough. Since the first connector 22, the second connector 23 and the support plate 20 are pressed and formed by the same metal plate, and the second connector 23 is sleeved on the first connector 22, it is necessary to make the length of the first horizontal portion 221 greater than the second horizontal portion 231, so that there is enough metal plate size to form a second L-shaped portion 232 larger than the first L-shaped portion 222, so that the second L-shaped portion 232 can be sleeved on the first L-shaped portion 222, and the first L-shaped portion 222 and the second L-shaped portion 232 structure combination constitute a space for placing the DC cable connected in series with the photovoltaic module. In addition, in the specific implementation, the support plate 20 is fixedly connected to the support seat 40 by rivets. The rivet is set at the center of the trough of the support plate 20, and the first connecting member 22 and the second connecting member 23 are attached and fixed at a position offset from the midpoint of the trough, which can avoid stress concentration and enhance the overall structural strength.

[0033] In addition, a heat dissipation pipe 60 is provided between the photovoltaic assembly 10 and the support seat 40, and a heat exchange medium is provided in the heat dissipation pipe 60 and is connected to an external driving device, and the heat exchange medium is driven to flow in the heat dissipation pipe 60 by the driving device. By setting the heat dissipation pipe 60, the heat in the photovoltaic assembly 10 is lost quickly, thereby improving the power generation efficiency of the photovoltaic assembly 10. In addition, the heat exchange medium can be water, and the driving member can be a water pump, and the unheated water is driven into the heat dissipation pipe 60 by the water pump, and flows out after the heat dissipation pipe 60 is heated, and is introduced into the lithium bromide refrigeration unit to achieve preheating of water, improve the utilization efficiency of solar energy, better realize building energy conservation, and reduce the power generation loss caused by the excessive temperature of the photovoltaic power generation system. In addition, the heat exchange medium can also be air, and the cold air is introduced into the heat dissipation pipe 60 by a fan, and in winter, the air heated by the heat dissipation pipe 60 can be passed into the building indoors, improve the indoor comfort, reduce the energy consumption of air conditioning, and achieve building energy conservation, killing two birds with one stone.

[0034] Specifically, the supporting connection sleeve 30 and the side of the supporting plate 20 are provided with avoidance grooves so that the heat dissipation pipe 60 is distributed in a serpentine shape under the photovoltaic module 10. Since the supporting plate 20 and the photovoltaic module 10 are fixedly connected by structural adhesive, and there are differences in thermal expansion coefficients between the structural adhesive and the supporting plate 20 and the photovoltaic module 10, in order to prevent local overheating, which may cause the structural adhesive area to detach or deform, it is necessary to distribute the heat dissipation pipe 60 in a serpentine shape to evenly dissipate heat for the entire module, reduce local temperature differences, and avoid deformation due to excessive local temperature differences.

[0035] In addition, see Figure 13 to Figure 14 as well as Fig.17 and Fig.18As shown, the support connecting sleeve 30 is filled with a phase change material 90, and the phase change material 90 is an organic paraffin, an inorganic hydrated salt of sodium sulfate decahydrate, calcium chloride hexahydrate or a eutectic mixture and a porous material such as diatomaceous earth, calcium carbide, and renewable plastic foam as a carrier, or a modified composite phase change material mixed with a thermal conductive material. By setting the phase change material 90 for auxiliary heat absorption, the heat dissipation effect of the device is further improved, thereby avoiding local overheating, which causes the structural adhesive area to fall off or deform. In addition, due to the filling of the phase change material 90, the supporting strength of the support connecting sleeve 30 is increased in a phase-changing manner, and the thickness of the support connecting sleeve 30 can be appropriately thinned to reduce the overall weight of the photovoltaic module. In addition, in the specific implementation, the space outside the support connecting sleeve 30 can also be filled with the phase change material 90, or the support connecting sleeve 30 is not set, and only the phase change material 90 is filled. In addition, a nozzle 62 may be provided on the heat dissipation pipe 60, that is, a connecting pipe 61 is provided locally on the heat dissipation pipe 60, and a plurality of nozzles 62 are provided on the connecting pipe 61, so that when water is used as a heat exchange medium, water can be sprayed out in the form of water mist through the nozzle 62, thereby further improving the heat dissipation effect. In addition, in a specific implementation, waterproof grooves 29 are provided on both ends of the support plate 20 near the heat dissipation pipe 60, and waterproof rubber strips may be provided in the waterproof grooves 29. By additionally providing the waterproof grooves 29 and the waterproof rubber strips, water flow in the nozzles 62 and the heat dissipation pipe 60 is prevented from entering the photovoltaic module 10.

[0036] In addition, a waterproof cover plate 70 is provided above the first connector 22 and the second connector 23, and a breathable waterproof component 80 is provided above the connection of the two supporting connection sleeves 30, and the tops of the waterproof cover plate 70 and the breathable waterproof component 80 are flush. The breathable waterproof component 80 can be a breathable waterproof film sandwiched between two metal parts. By providing the breathable waterproof film, cold air can enter to assist in heat dissipation, and rainwater can be prevented from entering to achieve a waterproof function. By providing the waterproof cover plate 70, the waterproof cover plate 70, the breathable waterproof component 80 and the top of the photovoltaic module 10 are flush to form a horizontal plane as a whole, forming a first layer of physical waterproof structure; after the corrugated metal plates of the product are overlapped and spliced, a second layer of physical waterproof structure is formed.

[0037] Specifically, the waterproof cover plate 70 includes a first horizontal plate portion 71, vertical plate portions 72 symmetrically arranged on both sides of the first horizontal plate portion 71, an inclined plate portion 73 extending inwardly from the vertical plate portion 72 and inclined, and a second horizontal plate portion 74 connected to the inclined plate portion 73. The two vertical plate portions 72 abut against the side of the photovoltaic module 10, the inclined plate portion 73 on one side abuts against the hypotenuse on the support plate 20, and the second horizontal plate portion 74 on the other side abuts against the second L-shaped portion 232. The vertical plate portion 72 abuts against the photovoltaic module 10, and the waterproof cover plate 70 moves left and right. Then, the inclined plate portion 73 on one side abuts against the hypotenuse on the support plate 20, and the second horizontal plate portion 74 on the other side abuts against the second L-shaped portion 232, so that the waterproof cover plate 70 is reduced to a certain height under the action of gravity, and the waterproof cover plate 70 is restricted from continuing to move downward, thereby realizing the rapid positioning of the waterproof cover plate 70, so as to improve the assembly efficiency of the assembled photovoltaic integrated module.

[0038] Also, see Figure 6 and Fig. 9 As shown, for example and not limitation, in some optional embodiments, a metal sheet can be spot welded between two troughs on the back of the support plate 20, and the heat dissipation pipe can be fixed by the metal sheet and the connection strength of the back of the support plate 20 can be strengthened to reduce the deformation amplitude of the front of the support plate 20 under stress, and make the combination between the components on the back and the support plate 20 smoother. In addition, the support plate 20 is formed by bending a single piece, and when subjected to the front extrusion force, it is easy to spread out to both sides like origami, therefore, by arranging a metal sheet at the bottom of the back crest of the support plate 20 to connect the two troughs, the strength of the trough structure is strengthened to prevent the compression force from stretching and deformation.

[0039] In summary, the present invention provides a wavy support plate 20 for supporting the photovoltaic module 10, and adjusts the distance between adjacent wave peaks so that the distance between adjacent wave peaks is less than the width of the construction personnel's soles or less than the width of the wheels of the construction equipment, so as to ensure that the support plate 20 provides sufficient support force to improve the compressive strength of the photovoltaic panel and avoid the photovoltaic panel from breaking. In addition, by providing a glue-containing groove 21, the photovoltaic module 10 is connected to the support plate 20, and a support connection sleeve 30 connected to the support plate 20 is provided and adjacent photovoltaic modules are connected to each other through the support connection sleeve 30. Then, by adopting this connection and fixing method, the friction and tearing effect of the clamp on the roof and the photovoltaic panel is avoided, and the service life of the photovoltaic module 10 is improved. In addition, the bending wave-shaped support plate 20 is used to support the photovoltaic module 10 and connect to the roof, which is lighter than the horizontal whole plate and the need for additional clamps. And semi-flexible crystalline silicon lightweight photovoltaic modules can be used to further reduce the weight of the photovoltaic module, so as to reduce the amount of steel used in the field of newly added steel structure buildings. In addition, by reasonably adjusting the position of the supporting connection sleeve 30, the connecting supporting sleeve and the supporting plate 20 cooperate with each other, thereby strengthening the mechanical structural strength of the longitudinal spacing, reducing the deformation of the photovoltaic integrated modular product when subjected to trampling pressure and hail impact pressure, and preventing the hidden cracks of the crystalline silicon cells of the photovoltaic module 10. In addition, through the socket connection of the supporting connection sleeve 30, and having sufficient pressure resistance, automatic assembly equipment can be used to improve the assembly efficiency. Therefore, the present invention solves the problem in the prior art of the lack of an assembled photovoltaic integrated modular product with light weight, strong pressure resistance, good waterproof performance, service life, high solar energy utilization rate and high assembly efficiency.

[0040] In addition, the present invention also provides a photovoltaic system, which includes a plurality of the above-mentioned assembled photovoltaic integrated modules. It should be noted that the photovoltaic system absorbs light energy through a plurality of photovoltaic units, performs photovoltaic power generation, and recycles the heat generated by photovoltaic power generation through heat dissipation pipes, thereby achieving a gradient utilization effect of energy, greatly increasing the efficiency of energy utilization, and meeting the needs of building energy conservation. In addition, since the heat dissipation pipe adopts a detachable split connection method, the heat dissipation pipe and its supporting heat recovery device can be set or not as needed. This allows the photovoltaic system to be adjusted according to customer needs, greatly increasing the scope of application of the photovoltaic system.
