Description

Technical Field

[0001] The utility model relates to the technical field of new energy, in particular to a novel photovoltaic module installation system. Background Art

[0002] For the installation of existing photovoltaic modules, as shown in CN219611696U and CN217643265U, most of the photovoltaic modules have frames installed on all four sides. The bottom of the frame is used to install the photovoltaic module on the roof or an external mounting bracket through connectors (such as an adhesive layer or threaded connectors) for outdoor use of the photovoltaic module. At the corner of two frames, corner brackets are also required for corner connection. Therefore, for each photovoltaic module to be installed outdoors, not only connectors are needed, but also four frames and four corner brackets; there are too many installation accessories, the installation process is complex, and the installation cost, transportation cost, and accessory input cost are high. The frame itself also occupies a certain installation area, resulting in less compact installation between photovoltaic modules. With the same installation area, the number of installable photovoltaic modules will decrease, which will affect the power generation of the photovoltaic system.

[0003] Moreover, for existing photovoltaic modules (as shown in CN219611696U and CN217643265U), usually holes are drilled in the middle area of the photovoltaic module (such as the photovoltaic backplane) to lead out the current collected by the internal busbars of the photovoltaic module to an external junction box by means of welding leads and then perforating, and then the leads of the junction box are used to achieve series and / or parallel connection between multiple photovoltaic modules. In this way, the frame and the junction box are installed in different areas. The frame and corner brackets will block the light at the four edges of the photovoltaic module, and the junction box (especially when the junction box is installed on the light-receiving surface of the photovoltaic module) and its leads will also affect the light absorption and light utilization rate in the middle area of the photovoltaic module, with a large shading area, which will greatly affect the power generation efficiency of the photovoltaic module. In addition, the junction box is usually installed in the middle area on the back of the photovoltaic module, and the junction box protrudes too much below the back of the photovoltaic module, which may also affect the installation of the frame on the roof or an external mounting bracket.

[0004] In addition, the publication number CN209066739U provides a frameless glass component installation structure, which omits the frame and uses a bolt installation method to install the photovoltaic component on the support hanger. In this way, the structure is simple, compact, the installation is faster, and the cost can be reduced. However, in this frameless glass component installation structure, the installation structure is still set at the edge position of the frameless glass component, and the junction box is usually installed in the middle area on the back of the photovoltaic component. Therefore, the installation area of the frameless glass component and the current drainage area of the junction box and the lead are still in different areas. Therefore, the frameless glass component and the junction box, etc. need to be respectively matched with different installation accessories for construction, and the process is still relatively complex, and the installation cost, transportation cost, and accessory input cost remain high. Moreover, the installation area of the frameless glass component and the current drainage area of the junction box and the lead are still in different areas, which will still affect the light absorption and light utilization rate of the frameless glass component, and the shading area is still large, which will affect the power generation efficiency of the photovoltaic component. The junction box protrudes too much below the back of the photovoltaic component, which may also affect the outdoor installation of the frameless glass component. Summary of the Utility Model

Detailed implementation manners

[0034] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the drawings and specific implementation manners.

[0035] Embodiment

[0036] A novel photovoltaic module installation system of this embodiment is shown in Figure 1-6 and includes a mounting plate 1, a photovoltaic module 2, a connecting member 3, and a bus bar gasket 5.

[0037] Among them, the photovoltaic module 2 is installed on one surface of the mounting plate 1 through the connecting member 3, and the bus bar gasket 5 is installed on the other surface of the mounting plate 1. Specifically, the photovoltaic module 2 is installed on the upper surface of the mounting plate 1, and the bus bar gasket 5 is installed on the lower surface of the mounting plate 1. The mounting plate 1 is a flat plate structure for carrying the photovoltaic module 2.

[0038] Among them, the photovoltaic module 2 includes a front photovoltaic panel 21, an adhesive film 22, a bus bar 24, a photovoltaic cell 23, and a back photovoltaic panel 25 provided below the front photovoltaic panel 21. The bus bar 24 and the photovoltaic cell 23 are arranged inside the photovoltaic module 2. The adhesive film 22 is filled between the front photovoltaic panel 21 and the back photovoltaic panel 25 to completely encapsulate the photovoltaic cell 23 and the bus bar 24 inside the photovoltaic module 2 through the adhesive film 22.

[0039] Furthermore, the photovoltaic cell 23 is provided with a plurality of electrode grid lines 231 (as shown in Figure 4 ) for electrical connection with the bus bar 24. Specifically, the photovoltaic cell 23 includes a plurality of cell sheets, each cell sheet is provided with a plurality of electrode grid lines 231, and the cell sheets are electrically connected to the electrode grid lines 231 through welding wires to form a battery string. The battery strings are electrically connected to the electrode grid lines 231 through the bus bar 24 to achieve series connection and / or parallel connection between the battery strings, thereby obtaining the photovoltaic cell 23. The middle section of the bus bar gasket 5 is partially provided with an inverted U-shaped contact portion 51 formed by upward bending (as shown in Figures 2-3, as shown in FIGS. 5-6). After the inverted U-shaped contact portion 51 sequentially passes through the mounting plate 1, the photovoltaic backsheet 25, and the encapsulant film 22, it is in electrical contact with the lower surface of the bus bar 24, so as to collect and lead out the current of each electrode grid line 231 on the photovoltaic cell 23 through the bus bar 24 and the bus bar gasket 5 to the outside of the photovoltaic module 2, and thus can provide electrical energy for external electrical equipment.

[0040] In practice, on the basis of without other auxiliary components, to ensure that the inverted U-shaped contact portion 51 can make close electrical contact with the lower surface of the bus bar 24, the height of the inverted U-shaped contact portion 51 is slightly greater than the distance from the bus bar gasket 5 on the lower surface of the mounting plate 1 to the bus bar 24.

[0041] In this embodiment, the projection plane of the region of the mounting connector 3 of the photovoltaic module 2 and the projection plane of the region of the bus bar gasket 5 electrically connected to the bus bar 24 at least partially overlap.

[0042] Preferably, a plurality of photovoltaic modules 2 are arranged on the upper surface of each mounting plate 1 (such as Figure 1 shown), and a plurality of bus bar gaskets 5 are correspondingly arranged on the lower surface of each mounting plate 1. The series connection and / or parallel connection of a plurality of photovoltaic modules 2 are realized through the electrical connection between the bus bar gaskets 5 (such as the way of external bolt wiring of the bus bar gasket 5 or other existing external connection methods) to collect the current of a plurality of photovoltaic modules 2. Installing a plurality of photovoltaic modules 2 on the upper surface of the same mounting plate 1 can make the arrangement of the photovoltaic modules 2 more compact and improve the power generation efficiency per unit area; moreover, the mounting plate 1 can simultaneously provide good mechanical support for a plurality of photovoltaic modules 2, so the load capacity of the photovoltaic module 2 can be improved, especially the load capacity on the back of the photovoltaic module 2.

[0043] Preferably, the photovoltaic module 2 is a frameless module. The frameless module can be installed on the upper surface of the mounting plate 1 through the connector 3, and the installation is convenient and fast. At the same time, the design of the frameless module makes the arrangement of the photovoltaic modules 2 more compact and improves the power generation efficiency per unit area.

[0044] The novel photovoltaic module installation system of this embodiment, through the cooperation of the connecting member 3, the mounting plate 1 and the busbar gasket 5, makes the projection plane of the current extraction area (i.e., the area where the busbar 24 is electrically connected to the busbar gasket 5) and the installation area (i.e., the area where the connecting member 3 of the photovoltaic module 2 is installed) at least partially overlap. In this way, it is not necessary to add a photovoltaic frame around each photovoltaic module 2, and the photovoltaic module 2 can be installed on the mounting plate 1 through the connecting member 3; it is also not necessary to add a junction box, and the installation area can be fully utilized to cooperate with the busbar gasket 5 to smoothly extract the current; and the free combination of series and / or parallel connection of several photovoltaic modules 2 can be realized through the external connection method of the busbar gasket 5 (such as the external bolt wiring method of the busbar gasket 5). This can cancel the frame and the junction box at the same time, reduce the manufacturing process of the photovoltaic module 2 and the novel photovoltaic module installation system, reduce the investment in installation accessories, and reduce the manufacturing cost, transportation cost and raw material input cost. Moreover, the free combination of series and parallel connection of several photovoltaic modules 2 is realized through the external connection method of the busbar gasket 5 (such as the external bolt wiring method of the busbar gasket 5), which can also flexibly adjust the current and voltage of the user according to the actual situation, is safe and reliable, convenient for maintenance and upgrading at the same time, and can avoid problems such as deformation of the busbar 24 caused by the welding of the existing junction box and the busbar 24. At the same time, the projection plane of the current extraction area and the installation area at least partially overlap, which can also improve the problem of excessive light shielding area of the photovoltaic module 2 caused by current extraction, installation, etc., and contribute to improving the photovoltaic power generation efficiency.

[0045] Among them, the busbar gasket 5 includes a conductor 52 and an insulating layer 53 wrapped around the outer surface of the conductor 52 (as Figure 5 shown), so as to prevent electric leakage from occurring outside the photovoltaic module 2, making it safer and more reliable. And the middle section of the busbar gasket 5 is locally electrically connected to the busbar 24 through the conductor 52 to ensure current conduction.

[0046] In an example of this embodiment, the connecting member 3 is an installation adhesive bonded between the photovoltaic module 2 and the mounting plate 1. Using the installation adhesive can further simplify the installation process and reduce the installation cost. However, the installation method of bonding with the installation adhesive is a non-detachable installation method, which has certain application limitations.

[0047] Therefore, another example is provided in this embodiment: that is, the connecting member 3 is preferably a screw connection member. The screw connection member includes a bolt 31 and a nut 32 (as Figures 2-3 shown); mounting holes 4 for one end of the bolt 31 to pass through are provided on the photovoltaic front plate 21, the busbar 24, the busbar gasket 5, the photovoltaic back plate 25 and the mounting plate 1 (as Figure 4 、 6As shown in Fig. -7. One end of the bolt 31 passes through the mounting holes 4 on the photovoltaic front plate 21, the bus bar 24, the bus bar gasket 5, the photovoltaic back plate 25 and the mounting plate 1 in sequence, and then is threadedly connected with the nut 32; in this way, the photovoltaic module 2 can be installed on the mounting plate 1 in a detachable manner, which is convenient for the disassembly and replacement of the photovoltaic module 2. Moreover, to ensure that at least part of the projection plane of the area of the mounting connector 3 of the photovoltaic module 2 overlaps with the projection plane of the area of the bus bar gasket 5 that electrically connects to the bus bar 24, the mounting hole 4 for one end of the bolt 31 to pass through the bus bar gasket 5 is correspondingly opened on the plane of the inverted U-shaped contact part 51 that contacts the bus bar 24, which can also reduce the number of openings on the photovoltaic back plate 25 and avoid the decline of mechanical properties and other properties of the photovoltaic back plate 25 due to excessive openings, so as to prevent the photovoltaic back plate 25 like photovoltaic glass from being fragile due to excessive openings.

[0048] Specifically, the bolt 31 is preferably a bolt made of insulating material. By the connection method of insulating bolts, there is no need to consider the creepage distance problem. The bolt 31 directly contacts the bus bar 24, the design is more compact, and the power generation efficiency per unit area of the photovoltaic module 2 is increased.

[0049] Furthermore, on the mounting plate 1, different mounting holes 4 can be correspondingly opened according to the arrangement mode of several photovoltaic modules 2 for the threaded installation and fixation of the photovoltaic module 2 by the screw connectors; the remaining positions of the mounting plate 1 can also be regularly opened to facilitate water leakage and reduce wind resistance.

[0050] In practice, the number of mounting holes 4 on the photovoltaic front plate 21 is the same as that on the photovoltaic back plate 25, and the positions of the mounting holes 4 on the photovoltaic front plate 21 and the photovoltaic back plate 25 are vertically corresponding; the number of mounting holes 4 on each photovoltaic front plate 21 and each photovoltaic back plate 25 is four, and the four mounting holes 4 are preferably correspondingly opened at the four corner positions of the photovoltaic front plate 21 (or the photovoltaic back plate 25) to improve the installation stability of the photovoltaic module 2 on the mounting plate 1.

[0051] In this embodiment, both the photovoltaic front plate 21 and the photovoltaic back plate 25 are photovoltaic glass. Or, the photovoltaic front plate 21 is photovoltaic glass, while the photovoltaic back plate 25 is a foam board or an acrylic board. Or, both the photovoltaic front plate 21 and the photovoltaic back plate 25 are other non-glass plates with high light transmittance and high strength such as foam boards or acrylic boards to further improve the load capacity of the photovoltaic module 2.

[0052] Furthermore, the screw connector further includes an anti-friction foam 33 (such as Figures 2-3, as shown in FIGS. 8); the anti-friction foam 33 includes a foam ring 331 and a foam cylinder 332 connected to the lower part of the foam ring 331. The foam ring 331 is attached to the outer surface of the photovoltaic glass (such as the photovoltaic front plate 21 or the photovoltaic back plate 25), and the foam cylinder 332 is attached to the inner side wall of the mounting hole 4 of the photovoltaic glass. Both the foam ring 331 and the foam cylinder 332 are provided with through holes 333 for one end of the bolt 31 to pass through. The anti-friction foam 33 is completely attached to the outer surface of the photovoltaic glass and the inner side wall of the mounting hole 4 of the photovoltaic glass. The bolt 31 passes through the through hole 333 in the middle of the anti-friction foam 33, which can avoid the direct contact between the bolt 31 and the photovoltaic glass and prevent the photovoltaic glass from bursting after touching the bolt 31.

Therefore, the appended claims are intended to be construed as including the preferred embodiments and all changes and modifications falling within the scope of the embodiments of the present invention.
