Description

Solar panels and their grounding connection structure

This invention provides a solar panel and its grounding connection structure, particularly a circuit that allows different solar panels to be grounded through the panel, eliminating the need for grounding configuration for each solar panel and improving the convenience and safety of solar panels during installation, assembly and grounding.

Note that solar power generation primarily converts sunlight into electrical energy. Therefore, it can be installed outdoors, generating electricity through sunlight. Consequently, solar power generation is often considered a relatively environmentally friendly method of power generation. Governments worldwide are actively promoting solar power technology, leading to its increasing maturity and wider application. Some countries combine their public facilities (such as streetlights) with solar panels to achieve power supply and improve management convenience; businesses and households can also generate electricity and supply their own power by installing solar panels, and the extra electricity can be sold back to relevant agencies. Therefore, the solar energy industry has formed a broad industrial chain.

Regarding the installation of solar panels, according to the regulations for the installation of electrical equipment by users, solar photovoltaic power generation systems must be grounded. The main reason is that grounding can ensure the safety of personnel during assembly, maintenance and repair. At the same time, it can also protect the equipment and prevent electrical faults, effectively prevent leakage and overvoltage, and ensure the stable operation of the entire system.

Currently, the grounding of solar panels typically involves individually configuring grounding wires on each solar panel for grounding connection. This process usually requires tapping the edges of each solar panel to ensure the grounding wires can be connected accordingly. This connection method is extremely time-consuming and labor-intensive, and there is often a concern that grounding may fail due to issues with tapping, which could result in screws not being securely fastened.

In view of this, we inventors devoted ourselves to further research on the grounding configuration of solar panels, and began to develop and improve it, hoping to solve the above problems with a better invention. After continuous experimentation and modification, this invention came into being.

Therefore, the purpose of this invention is to solve the aforementioned problems. To achieve the above objective, we, the inventors, provide a grounding connection structure for a solar panel, comprising: a sheet material disposed of as a conductive rigid material, the sheet being sheet-shaped, having an end face formed at one end, and having at least one abutment area formed at the end face; and having at least one positioning hole through the sheet; the sheet being used to press against the upper side edge of at least one solar panel or a frame on which the solar panel is disposed through the abutment area.

According to the above-described grounding connection structure of the solar panel, the panel body is made of a conductive composite material.

According to the above-described grounding connection structure of the solar panel, the panel has two abutting walls vertically arranged at the end face, and a gap is formed between the abutting walls.

According to the above-described grounding connection structure of the solar panel, the position of the positioning hole formed by the plate corresponds to the gap.

According to the above-described grounding connection structure of the solar panel, the contact area is further provided with a plurality of teeth.

According to the above-described grounding connection structure of the solar panel, a connecting wall is vertically provided on one side edge of the end face of the panel, and a connecting piece is provided on the connecting wall opposite one end of the panel, and the positioning hole is correspondingly provided through the connecting piece.

According to the above-described grounding connection structure of the solar panel, the connecting piece has a contact portion perpendicularly disposed at the side edge of the connecting wall towards one end of the connecting wall.

According to the above-described grounding connection structure of the solar panel, the panel body, the connecting wall, the connecting piece, and the contact part are arranged in a slightly stepped manner.

According to the above-described grounding connection structure of the solar panel, a contacting component is further protruding from the end of the contacting part.

A solar panel comprises a sheet having a grounding connection structure as described above, and further includes: a plurality of frames, each frame having a solar panel fixedly mounted therein; a water channel being provided between the frames; a connecting piece being provided in each water channel; the connecting piece having a connecting hole corresponding to the positioning hole; and the sheet pressing against the upper side edge of the solar panel or the frame through the abutment area; and at least one fixing element corresponding to and connected to the positioning hole and the connecting hole.

Based on the above description and setup, it is evident that this invention mainly possesses the following advantages and effects, which are detailed below:

1. This invention utilizes a rigid material with conductive properties, such as a conductive composite material, to provide an electrical connection for grounding the solar panels. It also assists in positioning the solar panels. When one solar panel is grounded directly or through the frame, all solar panels can be grounded, complying with user electrical equipment installation regulations and ensuring safety during power use. Furthermore, this invention allows for simultaneous grounding installation during solar panel installation, enhancing the convenience of installation, assembly, and grounding.

2. The present invention, through the configuration of the abutment walls, allows them to abut against the edges of the solar panel and its frame respectively, thereby assisting in the alignment and positioning of the solar panel and improving the accuracy of solar panel assembly.

3. By using the toothed part, this invention can increase the frictional force when in contact with the solar panel or its frame, so that the sheet can reliably engage with the solar panel or its frame, thus ensuring the stability of the grounding connection.

4. Through the configuration of the connecting wall and connecting piece, this invention can be applied to the positioning and grounding configuration of solar panels located at the outer edge. Through the setting of the abutment part and the contact part, it can be positioned and connected to the water guide channel, thereby improving the stability of this invention during assembly. At the same time, it can also help improve the stability and safety of the grounding configuration.

Regarding the technical means employed by us inventors, several preferred embodiments are described in detail below with accompanying drawings, so that you may gain a deeper understanding and appreciation of this invention.

Please refer to Figures 1 to 3. This invention relates to a solar panel and its grounding connection structure, which includes:

A sheet 1 is made of a rigid material with electrical conductivity. In a specific embodiment, the sheet 1 is made of a composite material with electrical conductivity, so as to enable it to be grounded and to have a certain strength. The sheet 1 is sheet-shaped, with an end face 11 formed at one end and at least one abutment area 12 formed at the end face 11. The sheet 1 is also provided with at least one positioning hole 13.

The sheet 1 is used to press against the upper side edge of at least one solar panel 2 or the frame 3 on which the solar panel 2 is disposed through the abutment area 12. Specifically, the solar panel 2 is preferably disposed within a frame 3 to facilitate stable positioning of the solar panel 2. Therefore, this invention is illustrated by the example of a solar panel 2 disposed on a frame 3 and connected to the frame 3 through the sheet 1, but it is not intended to be limiting.

To facilitate adaptation to weather conditions and to guide moisture or rainwater from the solar panels 2, preventing water accumulation on the solar panels 2 or direct accumulation or damage to the building due to leakage, it is preferable that a water channel 4 be provided between the frames 3. This arrangement allows water droplets on the solar panels 2 to be collected and discharged regardless of their direction. However, the configuration of the water channel 4 is merely illustrative and not intended to be limiting. In other embodiments, the solar panels 2 may not have the water channel 4.

Therefore, as shown in Figures 2 and 3, the present invention enables the overlapping of frames 3 of different solar panels 2 through the sheet 1. The conductive configuration of the sheet 1 allows for a grounded electrical connection between them. In one embodiment, the sheet 1 can be a simple rectangular sheet. More preferably, since the frames 3 of the solar panel 2 typically have gaps due to the arrangement of water channels 4, to ensure a stable connection between the sheet 1 and the frames 3, improve the stability of the connection, and increase the contact area with the frames 3, in a preferred embodiment, the sheet 1 is vertically oriented at the end face 11. Two abutment walls 14 are provided, and a gap 141 is formed between the abutment walls 14; thereby, as shown in Figure 3, the side edges of the frame 3 can correspondingly contact the abutment walls 14, while the upper edge of the frame 3 contacts the abutment area 12 of the sheet 1. As mentioned above, this increases the contact area and allows for uniformity in the spacing between the solar panels 2, which helps improve the accuracy of their assembly. Furthermore, the arrangement of the sheet 1, as shown in Figures 2 and 3, also helps to improve the overall stability of the solar panels 2 when they are extended and spliced, making them less prone to misalignment or displacement due to stress.

Regarding the positioning between the sheet 1 and the frame 3, in the case of a water guide channel 4, at least one set of connecting pieces 41 can be provided in the water guide channel 4, and the connecting pieces 41 are provided with connecting holes 411 corresponding to the positioning holes 13. At least one fixing element 5 can be provided, which is respectively corresponding to the positioning holes 13 and the connecting holes 411. Through the locking method, the sheet 1 can be locked by the fixing element 5, so that it is pressed against the contact area 12. The plate 1 is in contact with the upper edge of the frame 3. Specifically, the fastening element 5 may include a bolt 51 and a nut 52. The plate 1 can be positioned on the upper edge of the frame 3 by passing the bolt 51 through the positioning hole 13 and the assembly hole 411 and then locking the nut 52 at its end. However, the locking configuration is only an example and is not limited. It is understood that, in order to facilitate the locking configuration of the fastening element 5, the position of the plate 1 forming the positioning hole 13 corresponds to the gap 141.

To enhance the stability of the plate 1 and the frame 3 under pressure, in a preferred embodiment, a plurality of teeth 121 may be further provided in the contact area 12. As mentioned above, when the plate 1 and the frame 3 are in tight contact, the teeth 121 can also be used to tighten and engage the frame 3, so that the plate 1 can reliably and effectively make contact with the frame 3 to ensure its grounded electrical connection.

In this way, through the arrangement of the sheet body 1, all solar panels 2 can be grounded through the frame 3 and the sheet body 1, so that when one solar panel 2 is grounded, all solar panels 2 can be grounded at the same time, without the need to configure a grounding circuit for each solar panel 2. This improves the convenience and efficiency of assembling the solar panels 2, and at the same time complies with the relevant regulations for grounding the solar panels 2, thus ensuring safety during power use.

In another preferred embodiment, the solar panel 2 located at the edge usually also has a water channel 4 at its outer edge. To allow it to be connected to the water channel 4 for grounding, in one embodiment, to accommodate its shape, as shown in Figures 2, 4, and 5, a connecting wall 15 is more vertically provided on one side edge of the end face 11 of the panel 1. A connecting piece 16 is more horizontally provided on the connecting wall 15 opposite one end of the panel 1, and the positioning hole 13 is correspondingly inserted through the connecting piece 16. Connecting piece 16; thereby, the piece 1 is also used to press the bottom of the frame 3 at the upper edge, and the connecting wall 15 can be correspondingly attached to the side edge of the frame 3. The water channel 4 located at the outer edge of the frame 3 can also be provided with a connecting piece 41. As mentioned above, the piece 1 and the connecting piece 41 can also be locked together by a fixing element 5. The fixing element 5 passes through the positioning hole 13 of the connecting piece 16 and the assembly hole 411 of the connecting piece 41 to lock and fix the frame 3 and the piece 1.

To improve its stability during locking, it is preferable that the connecting piece 16 has a contact portion 17 vertically disposed on the side edge of the connecting wall 15, facing the end opposite to the connecting wall 15. The piece 1, the connecting wall 15, the connecting piece 16 and the contact portion 17 are arranged in a slightly integral stepped shape. This arrangement allows the contact portion 17 to be fitted against the side edge of the water channel 4, so that the piece 1 will not shift in the rotation direction during positioning, thereby improving the stability during positioning and ensuring that it can be connected to the grounding circuit of the water channel 4.

Preferably, to avoid any dimensional or assembly gaps or deviations between the abutment portion 17 and the side edge of the water channel 4, the end of the abutment portion 17 is further provided with a side abutment member 18. This allows the abutment member 18 to reliably abut against the side edge of the water channel 4 when the plate 1 is assembled with the assembly plate 41. This ensures a stable contact between the frame 3 of the solar panel 2 and the water channel 4 through the plate 1, thereby improving the effectiveness and stability of the grounding configuration. It also contributes to the overall stability during installation, allowing the solar panel 2 to be stably positioned and less prone to displacement due to force.

In conclusion, the technical means disclosed in this invention can effectively solve the problems of prior knowledge and achieve the expected purpose and effect.
