Description

A solar photovoltaic module and its installation method

Technical Field

The invention relates to the field of solar energy, and in particular to a solar photovoltaic component and an installation method thereof.

Background technique

With the rise in energy prices, the development and utilization of new energy has become a major research topic in the energy field today. Since solar energy has the advantages of being pollution-free, not geographically restricted, and inexhaustible, research on solar power generation has become the main direction for the development and utilization of new energy. Using solar cells to generate electricity is a major way for people to use solar energy today. Solar energy requires a large amount of land, such as roofs, so products that combine solar panels with roof tiles are more common. However, the current design of roof tile components faces the shortcoming of high cost and has not been widely applied and promoted.

If the rooftop photovoltaic module is to directly replace the roof structure, its waterproof ability must be able to meet the basic outdoor wind and snow natural conditions, and also meet the sustainable power generation capacity. In fact, the current photovoltaic module roof is not ideal in terms of structural sealing. It cannot be used in places that require strict watertightness, but is only suitable for breeding/planting/animal husbandry and other occasions. At the same time, it also faces the risk of anti-hidden crack failure during the installation and subsequent maintenance of the module. The ordinary backplane module process has weak anti-hidden crack ability, and the risk of hot spots after hidden cracks is aggravated, and the risk of failure is further expanded; in the conventional small rooftop tile module design, it also faces the problem of difficult installation. How to quickly install and facilitate subsequent maintenance is also a challenge.

The main crystalline silicon of traditional solar cells includes polycrystalline/monocrystalline silicon cell modules, but the conventional cell modules face the problem of poor resistance to hidden cracks after packaging due to the brittleness of crystalline silicon, which can easily lead to the failure to collect the subsequent hidden crack current, resulting in hot spots with concentrated current, local high current and high temperature, etc., which poses a serious risk of failure to the packaging materials of the components. In recent years, the market has also begun to gradually develop and apply double glass, but most of the double glass designs are frameless, and frameless double glass has no protection on all sides, which makes it easy to touch the edges and cause the panel to explode and fail, and it is also difficult to install, but it is completely overcome in terms of resistance to hidden cracks, and can achieve no hidden cracks. The market develops a large number of conventional frames every month because the frame is the most expensive material besides the cell, and the cost factor leads the market to choose frameless double glass applications. However, the hidden crack shortcomings of single glass modules, the easy explosion of double glass and the difficulty of installation are not the best product applications.

In addition, in the current application of frameless double-glass modules, there is also the existence of internal stress on all sides. The internal stress is caused by the current lamination and heating process of the modules. Long-term application of double-glass modules has the potential risk of edge warping. With long-term outdoor application, external moisture still has the opportunity to invade the interior, especially the application of double-glass modules on the water surface faces the risk of water vapor penetrating the edges, which poses a challenge to the surface oxidation of the battery cells and the continued high performance of the battery cells, and also poses a risk to the long-term quality commitment.

The current design of conventional components corresponds to two main installation methods: front clamping and back screw fixing. Back screw fixing is relatively strong but inconvenient to operate. When the front clamp is installed in typhoon areas, there are actually many cases where the components are loosened due to the loosening of the clamps, resulting in the loosening of the component string array and the components flying out and being damaged.

For the current bifacial cell power generation modules, including N-type bifacial and heterojunction modules, the bifacial double-glass structure is currently mainly used. The installation method also involves how to avoid back shading and meet the normal load mechanical performance. The conventional block installation method has low bearing capacity in terms of wind pressure and snow pressure. The module has insufficient support surface on the edge of the block and there is a risk of back shading.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, device, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

Example 1

In one embodiment of the present invention, two types of solar laminate connection mechanisms are provided for connecting two solar laminates. In this embodiment, the connection mechanism is composed of two frames, which are laminate frames, that is, the frame of the solar laminate in this application serves as a connection mechanism between two adjacent laminates 500. The first connection mechanism is used to connect the upper and lower laminates 500 (the solar laminate of this application is laid on a sloping roof, and there is a height difference between the upper and lower laminates 500). Referring to FIG. 2, the first connection mechanism includes A first strip-shaped frame 100 and a second frame 200, wherein the first frame 100 is provided with a first groove 110 and a cover plate 120, see FIG. 3 , and the second frame 200 is provided with a second groove 210, see FIG. 4 , the first frame 100 is connected and matched with the second frame 200, the first groove 110 and the second groove 210 are respectively used to accommodate the side edges of two adjacent laminates 500, and the outer edge of the cover plate 120 covers part of the upper surface of the second frame 200 (as shown in FIG. 2 ) or the entire upper surface (not shown) to eliminate the risk of rain leakage.

In order to facilitate the quick connection and installation of the upper and lower laminates 500, a clamping portion 121 is provided below the cover plate 120, see FIG3, and a third groove 220 is also provided on the second frame 200 to cooperate with the clamping portion 121, see FIG4, the first frame 100 and the second frame 200 are clamped and cooperated with the third groove 220 through the clamping portion 121, that is, the clamping portion 121 of the first frame 100 is embedded in the third groove 220 of the second frame 200, so that the upper and lower connection of the two laminates 500 can be realized, which is convenient and quick. Specifically, the clamping portion 121 can be a clamping strip of the same length as the cover plate 120, or it can be a distributed clamping block. Preferably, the clamping blocks are arranged at equal intervals below the cover plate 120. The present application does not limit the specific form of the clamping portion 121, and any structure that can cooperate with the third groove 220 should fall within the protection scope of the present application.

The second connecting mechanism is used to connect the left and right laminates 500, see Figures 7 and 8, the second connecting mechanism includes a first connecting member 410, a second connecting member 420, a clamping block 430 and two strip-shaped third frames 300, see Figure 6, the third frame 300 is provided with a fourth groove 310 opening in the horizontal direction and a fifth groove 320 opening upward, the fourth grooves 310 of the two third frames 300 are respectively used to accommodate the side edges of two adjacent laminates 500, the clamping block 430 is arranged in the fifth groove 320 of the two third frames 300, the first connecting member 410 and the second connecting member 420 are fixedly connected up and down, and the clamping block 430 is pressed tightly in the fifth groove 320.

In a specific embodiment, the first connecting member 410 is a bolt, and the second connecting member 420 is a nut, preferably a square nut, see Figure 15. The connecting mechanism also includes a drain groove 440, and the nut is relatively limitedly connected to the inner wall of the drain groove 440. The rectangular nut is designed with a circular arc design at the diagonal, which can easily insert the nut into the groove and realize the function of preventing rotation. The third frame 300 is also provided with a sixth groove 330 with an opening downward, which is connected to the nut by the bolt, and the groove walls on both sides of the drain groove 440 are respectively installed in the sixth grooves 330 of the two third frames 300, see Figure 7. The drain groove 440, on the one hand, serves as a support beam to support the third frame 300 and the entire photovoltaic module, and can also be used for drainage to achieve a secondary waterproof function.

Specifically, a rectangular nut is fixed in the drain groove 440. Specifically, the fixed bolt is extended from the inside of the drain groove 440, and the bolt can slide. The rectangular nut is connected to the inside of the drain groove 440 by welding or structural adhesive without destroying the sealing structure of the drain groove 440, thereby achieving an integrated good drainage sealing performance from top to bottom; at the same time, the fixing effect of the bolt and the rectangular nut is used to achieve a fixed connection between the two adjacent left and right frames; in addition, the cables of the junction box can also be routed along the supporting edge. In this embodiment, the clamping block 430 can adopt the H-type shown in Figure 12, or the U-type shown in Figure 13 or the type.

The third frame 300 is basically consistent with the second frame 200 in structure: the fourth groove 310 of the third frame 300 is consistent with the second groove 210 of the second frame 200, and the fifth groove 320 of the third frame 300 is consistent with the third groove 220 of the second frame 200. The only difference is that there may be no downward-opening groove at the bottom of the second frame 200 (corresponding to the sixth groove 330 of the third frame 300). However, in actual production, in order to simplify the classification of components, it is preferred that the second frame 200 adopts the structure of the third frame 300. Therefore, the present invention does not limit the specific structural form of the second frame 200 (whether it has a downward-opening groove).

In terms of waterproof structure, the second connection mechanism also includes a waterproof strip 450, which covers part of the upper surface (as shown in FIG8 ) or the entire upper surface (not shown) of the two third frames 300. The waterproof strip 450 is made of weather-resistant rubber strip, aluminum alloy, plastic steel, fiberglass steel, carbon steel or plastic material. The waterproof strip 450 is connected to the frame by silicone, double-sided tape or foam tape or by elastic rubber strip clamping. The waterproof strip 450 is used as a cover plate to prevent rainwater from penetrating from the middle of each component to the roof. The present invention uses the waterproof strip 450 as a primary rainwater barrier and uses the drain trough 440 to achieve a secondary drainage function, ensuring that the photovoltaic module installation method has a good waterproof function. The waterproof function here refers to preventing water from seeping from the upper surface of the photovoltaic module to the bottom. As a preferred embodiment, the waterproof strip 450 and the drainage trough 440 are respectively the width of the entire roof from top to bottom, that is, if the roof is covered with three horizontal rows and five vertical columns of photovoltaic modules, four waterproof strips 450 and/or four drainage troughs 440 are required, and each waterproof strip/drainage trough is installed in the gap between each two adjacent columns of photovoltaic modules. However, it should be noted that as another possible implementation method, the entire waterproof strip/drainage trough can be replaced by a plurality of spliced strips, for example, the lower end of the previous drainage trough 440 is accommodated in the next drainage trough 440, which will not be elaborated here.

During implementation, either the waterproof strip 450 or the drain groove 440 can be used to achieve waterproofing. However, in a preferred embodiment, both the waterproof strip 450 and the drain groove 440 are used to achieve secondary waterproofing, thereby obtaining a double waterproof protection effect.

The above two connecting mechanisms provide services for the installation of solar photovoltaic modules. In one embodiment of the present invention, a solar photovoltaic module is provided. If there is no waterproof requirement, the photovoltaic module includes a laminate 500, the first connecting mechanism as described above, or the second connecting mechanism as described above, that is, the laminate 500 of the photovoltaic module is quickly connected by using the first frame 100 and the second frame 200, and there is no requirement for the coverage of the cover 120, or the two third frames 300 are fixedly connected by using the clamping block 430 (the second frame 200 can also replace the third frame 300, see Figure 16), and there is no requirement for the waterproof strip 450 and the drain ditch 440 (but it is still necessary to fix the second connecting member 420 such as a nut mounting member under the third frame, see Figure 17).

In addition, when there is no waterproof requirement, there is no need to seal the fixed structure, including using the clamping block 430 to fix the two frames. There is no need to process and cut the frames, so a simple design can be directly achieved through the clamping block (no need for a sunken design), see Figure 17.

Obviously, those skilled in the art can make various changes and modifications to the invention without departing from the spirit and scope of the invention. Thus, if these modifications and variations of the invention fall within the scope of the claims of the invention and their equivalents, the invention is also intended to include these modifications and variations.

Example 2

In an embodiment of the present invention, a waterproof solar photovoltaic module is provided, including a laminate 500, a first connecting mechanism as described in Example 1, and a second connecting mechanism. Specifically, the laminate 500 is a rectangular block, composed of a plurality of rectangular cells arranged in a matrix form, and frames are provided on the sides of the laminate 500: a second frame 200 is installed on the upper side, a first frame 100 is installed on the lower side, and a third frame 300 is installed on both the left side and the right side. The laminate 500 is fixedly and sealedly connected to the first groove 110, the second groove 210 and the fourth groove 310.

The first groove 110, the second groove 210 and the fourth groove 310 are provided with a sealant 510 in a C-shaped enclosure between the laminate 500, see FIG2. In the optimization scheme, the first frame 100 is also provided with a barb 130, see FIG5. The barb 130 can block the sealant 510, reduce the front sealant overflow, avoid pollution, and achieve cleaning. In addition to the sealant, the frame and the laminate 500 are fixed with silicone or foam tape to prevent rain or moisture from corroding the battery cells through the EVA or POE from the side of the laminate 100, thereby performing 100% comprehensive internal sealing and protection structure around the laminate.

Furthermore, a frame is installed on the side of the laminate 500, and the frame includes a first frame 100, a second frame 200 and a third frame 300. The adjacent frames are bolted, bonded or overlapped at the intersection using an L-shaped corner code 600. In this embodiment, an L-shaped corner code 600 is provided, which is located at the edge of a single solar photovoltaic module and is fixed using the L-shaped corner code 600. The L-shaped corner code 600 is inserted into the corresponding slot design of the frame using automated equipment, so that a compact structure can be formed, but the protection and high strength of the frame can be met. The structure is shown in Figure 9. The L-shaped corner code 600 includes an L-shaped strip and three protrusions arranged on the L-shaped strip (three protrusions are arranged on one side, and one L-shaped corner code 600 includes 6 protrusions). The fixing method of the L-shaped corner code 600 to the frame is shown in Figures 10 and 11. The protrusions of the L-shaped corner code 600 respectively cooperate with the grooves on the frame, and the installation direction can be from top to bottom or from bottom to top. Through the L-shaped corner code, the adjacent frames on the same laminate 500 can be quickly fixed and connected at right angles.

Example 3

In a preferred embodiment of the present invention, the solar photovoltaic module is a double-glass photovoltaic module. In the prior art, the double-glass photovoltaic module has no frame because its own strength reaches a certain standard. In this embodiment, the double-glass photovoltaic module has a frame, and the frame is made of aluminum, aluminum alloy, plastic steel, glass fiber steel, carbon steel or plastic material. It meets the requirements of easy installation while meeting the requirements of lightness and high strength. Of course, the frame material can also be made of other metal materials that meet the above requirements. The frame can also be used for conventional single-glass photovoltaic modules by increasing the cross-sectional wall thickness or increasing the material strength.

Preferably, the height of the frame is 12 mm to 25 mm, that is, the frame adopts a very thin structural design, and the frame thickness of the entire photovoltaic module is less than 20 mm. On the one hand, a quick framing design is realized, and on the other hand, quick outdoor installation of each component is realized; the design of the clamping block 430 is utilized to realize the physical limiting function of each component, avoiding the risk of chain loosening and flying off when a single clamping block is loose.

It should be noted that: the battery cells in the present invention can adopt a double-glass structure, and can also adopt various crystalline silicon, which is not limited here; the crystalline silicon can be polycrystalline or single crystal, and various efficiencies are applicable; the battery cells can also be suitable for conventional welding processes, or low-temperature welding, or adhesive tape processes, or shingled assembly processes, without any restrictions on application; the battery cells can also adopt a conventional single-glass structure, and the process itself is not limited, but based on the basic actual needs of structural strength and resistance to hidden cracks in actual applications, it is possible to mainly consider multi-main-grid crystalline silicon battery cell assembly products, and the application of amorphous silicon products can also be considered; the circuit design includes half-cell, shingled circuit, and can adopt transparent or white EVA or glazed backplane glass, etc.

In addition, the frame structure provided by the present invention can be applied to a double-sided solar cell power generation assembly, and can meet normal load mechanical performance while avoiding back-side shading.

This embodiment also provides a solar roof, which utilizes the above-mentioned solar photovoltaic module installation method to arrange the laminated parts 500 of multiple photovoltaic modules in a matrix, and lays them on the roof top or beams to form a solar roof that can replace the traditional brick and tile roof, thereby achieving solar power generation and preventing rainwater.

In summary, the solar photovoltaic module provided by the present invention has a laminate 500 formed by a plurality of rectangular cells arranged in a matrix form, and the four sides of the laminate 500 are fixed with frames, and two adjacent frames overlap each other, and different laminates 500 are connected and installed through the frames. When the plurality of photovoltaic modules are assembled, the laminate 500 is inserted into the first groove 110, the second groove 210 and the fourth groove 310 to achieve snap-fitting, the frames are fixed with L-shaped corner codes 600, and the frames and the laminate 500 are fixed with sealant (silicone) or foam tape, which can prevent rainwater or water vapor from corroding the cells through EVA or POE from the side of the laminate 500, thereby forming a 100% comprehensive internal sealing and protection structure; the two adjacent left and right frames are overlapped by the snapping of the clamping block 430. According to the characteristics of the high and low inclination of the roof, the present invention uses the snapping of the frame and the clamping block to achieve a waterproof function; at the same time, the snapping between the upper and lower, left and right frames is used to achieve rapid installation and is not easy to fall off.

Obviously, those skilled in the art can make various changes and modifications to the invention without departing from the spirit and scope of the invention. Thus, if these modifications and variations of the invention fall within the scope of the claims of the invention and their equivalents, the invention is also intended to include these modifications and variations.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
