Description

A New Photovoltaic Module for Rooftop Environments

technical field

The utility model relates to the technical field of photovoltaic components, in particular to a novel photovoltaic component suitable for the roof environment.

Background technique

After more than ten years of rapid development in the global photovoltaic market, its global installed capacity has achieved rapid development. The focus of the market has also changed, from the past large-scale power stations on the ground to the direction of civilian roofs. Compared with the ground, the roof has its special installation environment, such as: limited installation area, higher height from the ground, and a certain inclination angle, etc., which brings new challenges to the design of photovoltaic modules.

Please refer to Figure 1. The frame structure of conventional photovoltaic modules is generally divided into three sides: A side 2, B side 3, and C side 4. The connection between the components and the system bracket 8 is realized by pre-drilling the installation hole 5 on the C surface 4. The position of the installation hole 5 and the installation cross-sectional view are shown in Figure 2. It can be seen from FIG. 3 and FIG. 4 that the component 1-1 can be installed on the system bracket 8 by means of a pressure block 11 or a bolt 9 and a nut 10. The layout of the battery 13 of the component 1-1 is shown in FIG. 5 . Conventional components have the following problems:

1. There are many components and the cost of materials is high. The installation of the conventional component 1-1 requires parts such as bolts 9, nuts 10, and pressure blocks 11. The increase in parts will not only increase the material cost of the system, but also bring great difficulties to the installation efficiency.

2. The installation efficiency is low. The installation of the conventional component 1-1 needs to insert the bolt into the installation hole 5 and then align the nut 9 in the system bracket 8, and then fix it. These two alignment operations are very difficult in the actual installation process, especially In the special environment of the roof, people can stand inside very small, so the installation efficiency is very low.

3. It is inconvenient to carry. The width of the component is nearly one meter, and it can only be carried by a single person in the mode of hand-held frame. In this mode, it is difficult to climb to a high place independently, and it needs the cooperation of someone to complete it, which increases the labor cost in the installation process.

4. The roof space cannot be fully utilized. Because the width of this component is 1 meter, when there is still a gap close to 1 meter in the roof, another component 1-1 can not be installed, and it can only be vacant, so the roof area cannot be effectively used.

5. The longer busbar 12 affects the power output of the module. As shown in Figure 5, since the centralized junction box 6 is used, it is necessary to use the bus strip 12 to connect the welding strips in series and lead them to the position of the junction box 6. In this way, due to the resistance of the bus strip 12 itself, it will inevitably cause internal The increase in resistance reduces the power output of the module.

There is also a quick installation component 1-2 in the prior art. Compared with the conventional component 1-1, the only difference is that the frame structure is different. By designing frames with different structures, a new type of installation method can be adopted, thereby improving the efficiency of component installation. Its schematic diagram is shown in Figure 6 and Figure 7. Put the clip 14 flatly into the notch in the frame, and then rotate it, so that the clip 14 is in a vertical state inside the frame, and the assembly is fixed. The size of the clip 14 and the size of the frame notch are the key points of the frame .

However, the quick installation module 1-2 has unavoidable defects in the processing of the frame besides the inconvenient handling, the inability to fully utilize the roof space, and the long confluence belt 12 affecting the power output of the module.

Moreover, the production process is difficult, and the dimensional accuracy between the notch of the frame and the clamp head 14 is required to be very high. If the size of the notch is too large, the clamp head 14 will not be clamped, and if the size of the clamp head 14 is too large, it will not be able to penetrate into the slot. Therefore, the difficulty of the frame production process is increased, the yield rate of the frame is reduced, and the cost of the frame production is increased. At the same time, in the framing process of the component package, the pressure must be strictly controlled to avoid deformation due to excessive force, which increases the difficulty of the component production process. Extremely expensive to produce.

Therefore, how to make full use of the effective area of the effective roof, and how to quickly and safely install photovoltaic modules on the roof has become an urgent problem to be solved in the photovoltaic industry.

Detailed ways

The utility model discloses a novel photovoltaic assembly suitable for the roof environment, which can realize rapid and safe installation on the roof.

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 8, Fig. 11, Fig. 12, Fig. 13 and Fig. 14, the new photovoltaic module suitable for the roof environment provided by the embodiment of the utility model includes:

There are not less than two photovoltaic module bodies 1-3, and a large new photovoltaic module is composed of multiple smaller modules, which makes the module have a higher degree of freedom from design and production to installation and use. The modules can be combined and installed It can also be disassembled and installed separately, especially suitable for special environments such as roofs;

The slider 16, the slider 16 has a chuck that matches the notch of the frame of the photovoltaic module body 1-3, and is used for fixing and installing the photovoltaic module body 1-3;

A connector group that connects any two adjacent photovoltaic module bodies 1-3. The connector group includes two connectors 15 hinged at one end by pins. The two connectors 15 are connected together in the form of pins, and the slider 16 is connected with bolts, and then the slider 16 is inserted into the frame notch of the photovoltaic module body 1-3, thereby realizing the connection of the two photovoltaic module bodies 1-3. When the two photovoltaic module bodies 1-3 are opened, relying on the thickness of the connector 15 will ensure that the maximum opening angle of the two photovoltaic module bodies 1-3 can only be 180 degrees, so as to ensure that the new photovoltaic module will not be damaged during use. Will move against the wind.

The new photovoltaic module suitable for the roof environment provided by the embodiment of the utility model is composed of no less than two photovoltaic module bodies 1-3. Due to the special installation environment of the roof, moving the module up and down consumes a lot of manpower and material resources. The new photovoltaic module is in a closed state during the handling process, which is convenient for manual handling. Moving one new photovoltaic module is equivalent to handling 1.33 conventional modules, which greatly improves the handling efficiency and reduces the system installation cost; usually the roof area is small , the photovoltaic power generation system should use the space more effectively and to a greater extent. Compared with conventional components, this module is slender and can be disassembled and installed, so it can improve the space utilization of the module; and any two adjacent photovoltaic module bodies 1-3 are hinged by a connector group, which not only realizes the connection of the two parts, but also realizes the fixing function of the two parts after they are unfolded and flattened. Therefore, the number of pressing blocks during system installation can be saved , saving raw materials and installation labor costs; the components can be installed in combination or disassembled for separate installation, enabling fast and safe installation on the roof.

As shown in Figure 5, the photovoltaic modules 1-1 in the traditional structure have a width of nearly 1 meter. When transported by a single person, only the hand-held frame mode can be used. In this mode, it is difficult to climb to a high place independently and requires the cooperation of others. , Increase the labor cost in the installation process. And because the width of this module 1-1 is 1 meter, can not install a piece of module 1-1 again when there is still the gap close to 1 meter in the roof, can only come out vacantly, therefore can not effectively utilize roof area. Therefore, in this embodiment, the shape and size of the photovoltaic module body 1-3 are improved. Specifically, the outer dimensions of each photovoltaic module body 1-3 are: 1630mm×685mm, 1475mm×685mm or 1320mm×685mm. The area of each part of the photovoltaic module body 1-3 is usually one-third smaller than that of the module, so the requirement for the strength of the frame will be reduced, and the thickness of the frame will be greatly reduced, which can improve the single box of the module. The number of components can be accommodated, reducing the cost of component transportation.

Please refer to Figure 2, there is a label 7 and a junction box 6-1 on the back of the module. In the traditional junction box 6-1, three diodes are integrated in one box, so the busbars of different battery strings need to guide the middle position of the module. Connection, which not only increases the amount of bus belt, but also increases the internal resistance of the module and reduces the power output of the module. The heat dissipation of the junction box will also affect the output power of the components. In order to solve this problem, in this embodiment, as shown in Figure 9, the junction box 6-2 on each photovoltaic module body 1-3 is a separate type, and the separate type of two adjacent photovoltaic module bodies 1-3 The junction box is connected by connectors. In this way, by using a separate junction box, the length of cables and busbars is saved, and the heat dissipation of the junction box affects the power generation of the components.

In order to further optimize the above technical solution, as shown in Figure 14, the front end of the slider 16 has a trapezoidal structure, and as shown in Figure 10, the frame notch of the photovoltaic module body 1-3 has a structure that matches the trapezoidal clamp , making the installation and fixing of photovoltaic modules more firm and reliable.

There are many ways for the slider 16 to be installed on the connector 15, including threaded connection or surface connection and the like. In this embodiment, the mounting portion is specifically the first mounting hole 15-2, the slider 16 is provided with a second mounting hole 16-1 corresponding to the first mounting hole 15-2, and the bolt passes through the first mounting hole 15 -2 and the second mounting hole 16-1 connect the connector 15 and the slider 16 together.

Please refer to Figure 11, Figure 12, Figure 13 and Figure 14, the part of the connector 15 with the first mounting hole 15-2 is also provided with a mounting groove 15-3, and the part opposite to the slider 16 is provided with a mounting groove 15-3 The matching protrusion 16-2 forms a T-shaped slider, and such a structure facilitates the matching connection between the two.

Further, the installation groove 15-3 is specifically a hexagonal installation groove, and the protrusion 16-2 is specifically a hexagonal protrusion matched with the hexagonal installation groove.

The embodiment of the utility model provides a new type of photovoltaic module suitable for the roof environment. The main body of the photovoltaic module 1-3 is two pieces, which are hinged by a set of connectors, and then fixed on the system bracket 8 .
