Description

Technical Field

[0001] The utility model relates to the technical field of solar cells, in particular to a solar panel. Background Art

[0002] At present, photovoltaic modules on the market all use a grid backplane to block the gaps between the cell strings and the white bus bars. The principle of using a grid backplane to block the gaps between the cell strings and the white bus bars is to set a strip of black coating on the transparent front panel or back panel to block the bus bars. However, since it is necessary to add parameters or brand information to the solar panels, the related technologies all use built-in stickers on the inside of the front panel or back panel, and realize LOGO (Logotype, logo, trademark) display or parameter display after lamination, or directly stick the LOGO, etc. on the outside of the front panel. Since the front panel and the back panel are provided with a black coating, the black coating will block the built-in stickers on the inside of the front panel or the back panel, so that the LOGO and other signs cannot be seen from the outside. When the LOGO is directly attached to the outside of the front panel, the sticker will be aged, faded, scratched and damaged after long-term use.

[0003] Therefore, how to design a solar panel with a label and ensure the service life of the label has become an urgent problem to be solved. Utility Model Content

[0004] The utility model aims to at least solve the problem that labels on solar panels existing in the prior art or related art are easily damaged and have a short service life.

[0005] To this end, a first aspect of the present invention provides a solar panel.

[0006] In view of this, the first aspect of the utility model proposes a solar panel, including a solar panel body, the solar panel body including: a first substrate; a second substrate, arranged on one side of the first substrate; a battery assembly, arranged between the first substrate and the second substrate; a shielding coating, arranged on the first substrate and / or the second substrate, for shielding part of the battery assembly; an identification coating, arranged on the first substrate and / or the second substrate.

[0007] The solar panel provided by the utility model includes a solar panel body, and the solar panel body includes a first substrate, a second substrate, a battery assembly, a shielding coating and an identification coating. The second substrate is arranged on one side of the first substrate, the battery assembly is arranged between the first substrate and the second substrate, and the shielding coating is arranged on the first substrate and / or the second substrate, which can shield part of the battery assembly, thereby improving the overall aesthetics of the solar panel. Specifically, the shielding coating is arranged on the first substrate, or the shielding coating is arranged on the second substrate, or the shielding coating is arranged on both substrates, which can be arranged according to actual conditions. In addition to the above-mentioned settings, the present application is also provided with an identification coating, through which the parameters, brand and other information of the solar panel can be displayed, so that the user can understand the solar panel more intuitively. Specifically, the identification coating can be arranged on the first substrate and / or the second substrate by printing or painting. Compared with directly sticking the label on the outside of the solar panel, the identification coating is not easy to be damaged, and the service life can be increased. At the same time, since the identification coating is printed or applied on the first substrate and / or the second substrate, when the shielding coating and the identification coating are both arranged on the first substrate or both arranged on the second substrate, and the shielding coating and the identification coating overlap, the identification coating can be printed or applied on the first substrate and / or the second substrate first, and then the shielding coating is arranged, so as to ensure that the identification coating is not blocked by the shielding coating.

[0008] The solar panel provided by the utility model may also have the following additional technical features:

[0009] In some embodiments, optionally, the battery assembly includes: a battery string; a bus bar connected to the battery string, and the shielding coating is used to shield the bus bar.

[0011] In some embodiments, optionally, the shielding coating is disposed between the first substrate and the second substrate, and the marking coating is disposed between the first substrate and the second substrate.

[0012] In this embodiment, the shielding coating and the identification coating can be arranged between the first substrate and the second substrate, that is, the shielding coating and the identification coating are arranged on the inner side of the first substrate and the second substrate to avoid the shielding coating and the identification coating being exposed to the outside, thereby reducing the probability of damage to the shielding coating and the identification coating, thereby increasing the service life of the shielding coating and the identification coating.

[0013] In some embodiments, optionally, the identification coating is disposed between the shielding coating and the first substrate; and / or the identification coating is disposed between the shielding coating and the second substrate.

[0014] In this embodiment, the marking coating can be disposed between the shielding coating and the first substrate. That is, the marking coating and the shielding coating are disposed in an overlapping manner, and because the marking coating is disposed between the shielding coating and the first substrate, the marking coating can be seen from the other side of the first substrate, thereby preventing the shielding coating from shielding the marking coating. Similarly, when the marking coating is disposed on the second substrate, it is the same as being disposed on the first substrate, that is, the marking coating is disposed between the shielding coating and the second substrate.

[0015] In some embodiments, optionally, the marking coating and the shielding coating are made of different materials.

[0016] In this embodiment, the materials of the marking coating and the shielding coating can be set to be different, so that when the marking coating and the shielding coating are overlapped, the marking coating can be more clearly distinguished.

[0018] In this embodiment, the solar panel body also includes a protective layer, which is arranged on the side of the first substrate away from the second substrate, and can protect the first substrate, thereby increasing the service life of the first substrate. Similarly, a protective layer can also be arranged on the side of the second substrate away from the first substrate, so as to protect the second substrate. The solar panel body also includes a first adhesive film layer and a second adhesive film layer, and the first adhesive film layer is arranged between the first substrate and the battery assembly. The second adhesive film layer is arranged between the second substrate and the battery assembly. By arranging the first adhesive film layer and the second adhesive film layer, the battery assembly can be effectively fixed between the first substrate and the second substrate.

[0019] In some embodiments, optionally, the solar panel further includes: a frame, in which the solar panel body is disposed; and a fixed installation structure disposed on the outside of the frame for fixedly installing the solar panel.

[0020] In this embodiment, the solar panel also includes a frame, and the solar panel body is arranged in the frame, so that the solar panel can be fixed by the frame, and the solar panel can be installed in a preset position by the frame. In order to facilitate the fixed installation of the frame, a fixed installation structure can be arranged on the outer side of the frame, so that the solar panel can be fixedly installed by the fixed installation structure.

[0021] In some embodiments, optionally, the solar panel further includes: a junction box, disposed on the frame and connected to the battery assembly.

[0022] In this embodiment, the solar panel further comprises a junction box, which is arranged on the frame, facilitating the fixed installation of the junction box. The junction box is connected to the battery assembly, so that the electricity generated by the battery assembly can be exported.

[0023] In some embodiments, optionally, the height of the frame is greater than or equal to 1 mm and less than or equal to 4 mm.

[0024] In this embodiment, the height of the frame can be set to be greater than or equal to 1 mm and less than or equal to 4 mm, which is conducive to the installation of the solar panel body. It can be understood that the height direction of the frame here is the same as the thickness direction of the solar panel body. During installation, glue can be directly applied on the inside of the frame, and then the solar panel body can be fixed in the frame by glue.

[0025] In some embodiments, optionally, the battery component includes a thin film battery component and a crystalline silicon battery component.

[0026] In this embodiment, the battery components include thin film battery components and crystalline silicon battery components. The thin film battery components and crystalline silicon battery components can produce photovoltaic effect, thereby converting solar energy into electrical energy to achieve solar power generation.

[0027] In some embodiments, optionally, the transmittance of the first substrate and the second substrate is greater than or equal to 85%.

[0028] In this embodiment, by limiting the transmittance of the first substrate and the second substrate to be greater than or equal to 85%, it can effectively ensure that light is irradiated on the battery assembly, thereby ensuring the power generation efficiency of the solar panel. The transmittance here refers to the transmittance of the first substrate and the second substrate before the shielding coating is set.

[0029] In some embodiments, optionally, the total thickness of the first substrate and the second substrate is greater than or equal to 0.2 mm and less than or equal to 0.6 mm.

[0097] According to an embodiment of the first aspect of the present utility model, Figure 6 As shown, a solar panel 1 is proposed, including a solar panel body 12, wherein the solar panel body 12 includes a first substrate 121, a second substrate 122, a battery assembly 123, a shielding coating 124, and a marking coating 125. The second substrate 122 is arranged on one side of the first substrate 121. The battery assembly 123 is arranged between the first substrate 121 and the second substrate 122. The shielding coating 124 is arranged on the second substrate 122 to shield part of the battery assembly 123. The marking coating 125 is arranged on the second substrate 122.

[0098] The solar panel 1 provided by the utility model includes a solar panel body 12, and the solar panel body 12 includes a first substrate 121, a second substrate 122, a battery assembly 123, a shielding coating 124 and a marking coating 125. The second substrate 122 is arranged on one side of the first substrate 121, the battery assembly 123 is arranged between the first substrate 121 and the second substrate 122, and the shielding coating 124 is arranged on the second substrate 122, which can shield part of the battery assembly 123, thereby improving the overall aesthetics of the solar panel 1. In addition to the above-mentioned settings, the present embodiment is also provided with a marking coating 125, through which the parameters, brand and other information of the solar panel 1 can be displayed, so that the user can more intuitively understand the solar panel 1. Specifically, the marking coating 125 can be set on the second substrate 122 by printing or painting. Compared with directly sticking the label on the outside of the solar panel 1, the marking coating 125 is not easy to be damaged, and the service life can be improved. At the same time, since the identification coating 125 is printed or applied on the second substrate 122, when the shielding coating 124 and the identification coating 125 overlap, the identification coating 125 can be printed or applied on the second substrate 122 first, and then the shielding coating 124 is set, so as to ensure that the identification coating 125 is not blocked by the shielding coating 124.

[0099] According to an embodiment of the first aspect of the utility model, a solar panel 1 is proposed, which can achieve double-sided power generation and a completely black appearance, and the grid backplane (first substrate 121 and second substrate 122) can display a LOGO while hiding the ugliness. The solar panel 1 includes a solar panel body 12, and the solar panel body 12 includes a battery assembly 123, a front plate (first substrate 121) and a back plate (second substrate 122). The front plate and the back plate are transparent plates, and the front plate and the back plate are provided with a silk screen area (shielding coating 124) and a logo coating 125. The transmittance of the non-silk screen area is above 85%, and the total thickness is between 0.2mm and 0.6mm.

[0100] Specifically, when making the solar panel 1, you can first screen-print a LOGO (logo coating 125) on the transparent front panel. The color is generally white or orange. After the screen-printed LOGO is cured, the shielding coating 124 area is screen-printed. The shielding coating 124 can be a black area. The black area covers the LOGO area. The part without the screen-printed shielding coating 124 corresponds to the battery area. There is a gap between the battery strings 1232.

[0101] The front plate is made of transparent material such as PET, and is coated with a weather-resistant fluorine film coating, such as ETFE or PVDF, to provide UV protection for the bottom layer of PET, etc. The inner side of the front plate is a screen-printed shielding coating 124 and a logo coating 125, and the outer layer is a weather-resistant coating.

[0102] The back panel can be selectively screen-printed with a LOGO, and then a black area with the same shape as the front panel can be screen-printed, which is a symmetrical structure. The solar panel body 12 also includes a film layer, which can provide bonding, and is generally made of EVA, EPE, POE, etc. The battery cell (battery assembly 123) can be selected as a thin film type, a crystalline silicon type, etc., which can produce a photovoltaic effect. This laminated structure is completed by integral lamination to complete the setting of the solar panel body 12, and the total thickness is between 2.5mm and 4mm.

[0103] The battery assembly 123 includes a battery string 1232 and a bus bar 1234, and the bus bar 1234 includes a positive and negative bus bar 1234. The solar panel body 12 is formed after cutting. The solar panel 1 also includes an aluminum alloy frame 14, and the thickness of the aluminum alloy frame 14 can be selected to be 2mm to 3.5mm in inner width. The inner side of the frame is glued and assembled with the solar panel body 12. An air avoidance area is set on the outer side of the frame 14, and the air avoidance area is used to provide installation and fixing holes.

[0104] In summary, this application is to screen print the inside of the transparent front panel twice, the first time to screen print the LOGO, and the second time to screen print black to cover the logo area. The back panel is screen printed in the same way as the front panel, and whether the LOGO layer is needed is determined based on the necessity of displaying the back panel LOGO. The portable solar panel is a double-sided structure with a 5-layer symmetrical structure, front panel + film + battery + film + back panel. The main body of the portable solar panel is a special-shaped structure, and the air-avoiding area is used to provide installation and fixing holes. The product also includes an aluminum alloy frame, corner brackets and junction boxes.

[0105] The solar panel 1 can achieve an overall black appearance. The solar panel body 12 is specifically a front panel + adhesive film + battery + adhesive film + back panel structure. The back panel can play the role of electrical insulation and water vapor barrier.

[0106] Beneficial effects of this application:

[0107] 1. By silk-screening the front and back panels, it can not only meet the double-sided structure, but also cover the surrounding bus bars, ensuring the black beauty of the product, and can also display the LOGO on the front or back of the product. The LOGO can meet the long-term use function and avoid fading or damage after being exposed on the outside for a short time.

[0108] 2. The front panel and back panel can provide protection for the front and back of the solar panel. The front panel uses a composite coating to add a weather-resistant layer, which can also prevent the battery from cracking due to bumps.

[0109] 3. The aluminum alloy frame and corner brackets provide rigidity to the product, achieving lightweight and high-strength functions. The airtight position can not only reduce weight, but also provide installation holes such as fixing screws, which is convenient for installation and fixation in different application scenarios such as balconies and roofs.
