Description

Technical Field

[0001] This utility model relates to the field of solar photovoltaic module technology, specifically to a solar photovoltaic module with light-emitting diodes for mounting on the exterior surface of a building. Background Technology

[0002] Generally speaking, solar power generation is more environmentally friendly than traditional methods like coal-fired power generation. Unlike the past, which produced carbon dioxide, sulfides, and nitrogen oxides through combustion, causing environmental pollution, existing solar photovoltaic modules are typically made of silicon semiconductor materials. They have low energy loss during long-term operation and can absorb sunlight and convert photon energy into electrical energy using the photovoltaic effect. Smaller solar photovoltaic modules can power watches or computers, while larger modules can power photovoltaic systems for home lighting or even supply power to the grid.

[0003] The larger solar photovoltaic modules mentioned above are generally divided into rooftop and ground-mounted types. Rooftop solar photovoltaic modules are installed on the roof of buildings, while ground-mounted solar photovoltaic modules are installed on the ground. However, in cities, due to the limited roof area of ​​buildings and the scarcity of open ground space, it is difficult to widely use rooftop and ground-mounted solar photovoltaic modules. Furthermore, traditional solar photovoltaic modules are limited to absorbing light, storing energy, and generating electricity, without any other additional functions. Therefore, the general public or companies only need to consider the single function of a solar photovoltaic module when deciding whether to use it.

[0004] In view of the above problems, in order to increase the proportion of green energy used in cities, raise the utilization rate of solar photovoltaic modules in cities, and enhance the attractiveness of solar photovoltaic modules for purchase and use, it is necessary to improve the usage of solar photovoltaic modules and add additional functions. How to improve and add functions that complement solar photovoltaic modules to meet the needs of the public or companies is the main goal of manufacturers in developing solar photovoltaic modules. Utility Model Content

A corresponding number of solar photovoltaic modules can be used for the exterior surface area of ​​buildings of various sizes, and these modules can be interlocked and hung on the building's exterior surface. Furthermore, the surface of the solar photovoltaic module is equipped with light-emitting diodes (LEDs). The light emitted by these LEDs can be used for nighttime illumination or to beautify the building's walls, and can also be used to confirm the functional status of the solar photovoltaic module.

[0006] Another objective of this invention is to provide a solar photovoltaic module coated with a self-cleaning layer. In this invention, the self-cleaning layer protects multiple solar cells and their first surface from organic impurities, preventing direct contact with these impurities and thus reducing light reception efficiency. Therefore, when organic impurities adhere to the self-cleaning layer, it acts as a catalyst, absorbing solar energy and then combining with and decomposing the impurities to clean the surface. Furthermore, since the solar photovoltaic module of this invention includes metal wires embedded within it, when the module is used in low-temperature environments and frosts, the metal wires can absorb the electricity transmitted by the multiple solar cells and convert it into heat for defrosting.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] To better realize the above technical solution, the solar photovoltaic module can be interconnected with another solar photovoltaic module.

[0011] Furthermore, the solar photovoltaic module is connected to the first bend of another solar photovoltaic module through its second bend.

The first connecting portion or the second connecting portion includes a locking portion, and the third connecting portion or the fourth connecting portion has a groove. When the aforementioned solar photovoltaic module is connected to another identical solar photovoltaic module, the second surface of the substrate of the aforementioned solar photovoltaic module is adjacent to the first surface of the substrate of the other identical solar photovoltaic module. Furthermore, the connection between the aforementioned solar photovoltaic module and the other identical solar photovoltaic module can also be achieved by using the second bending portion of the aforementioned solar photovoltaic module to engage with the first bending portion of the other identical solar photovoltaic module. Moreover, the connection between the aforementioned solar photovoltaic module and the other identical solar photovoltaic module can also be achieved by using the groove of the fourth connecting portion of the second bending portion of the aforementioned solar photovoltaic module to engage with the locking portion of the first connecting portion of the first bending portion of the other solar photovoltaic module.

[0013] Optionally, the aforementioned locking portion is in the shape of a barb. The shape of the aforementioned substrate includes, but is not limited to, a square, a rectangle, or other shapes.

[0014] Alternatively, the aforementioned solar cells can be further classified as perovskite solar cells.

[0016] Optionally, a self-cleaning layer is coated on multiple solar cells and the first surface, and its function is to protect the multiple solar cells and the first surface from the adhesion of organic impurities.

[0030] The present invention discloses a solar photovoltaic module, as shown in Figure 1(a) which illustrates a front view of the solar photovoltaic module 100 according to an embodiment. The solar photovoltaic module 100 of the present invention can be installed on the outer surface of a building (e.g., roof, side wall, or sloping wall).

[0031] The surface of this solar photovoltaic module is further provided with light-emitting diodes (LEDs).

The first bent portion 106 is connected to the upper edge of the first surface 1022. The LEDs 108 are disposed on the first surface 1022 and surround the groove 1021. In one embodiment, the shape of the substrate 102 includes, but is not limited to, a square, a rectangle, or other shapes.

[0032] In some embodiments, the first bending portion 106 includes a first connecting portion 1061 and a second connecting portion 1062, with the first connecting portion 1061 adjacent to the second connecting portion 1062.

[0033] In one embodiment, the first connecting portion 1061 and the second connecting portion 1062 are arranged to form an inverted V shape, and the first connecting portion 1061 or the second connecting portion 1062 has a locking portion 1063.

[0034] In some embodiments, the locking part 1063 is in the shape of a barb.

[0035] Please refer to Figure 1(b), which shows a front view of the solar photovoltaic module 100 of this invention using another embodiment. The self-cleaning layer 110 of the solar photovoltaic module 100 of this invention is made of titanium dioxide.

[0036] In one embodiment, a self-cleaning layer 110 is coated on a plurality of solar cells 104 and a first surface 1022, and its function is to protect the plurality of solar cells 104 and the first surface 1022 from being adhered to by organic impurities. If organic impurities adhere to the self-cleaning layer 110, the self-cleaning layer 110 can act as a catalyst and receive energy from the solar source, and then combine and decompose the organic impurities to achieve the effect of cleaning the surface of the self-cleaning layer 110.

[0037] In one embodiment, a self-cleaning layer 110 is coated on the light-emitting diode 108.

[0038] Please refer to Figure 1(c), which shows a rear view of the solar photovoltaic module 100 of this invention according to an embodiment. As can be seen from the rear view, the solar photovoltaic module 100 of this invention further includes a second surface 1023, a second bent portion 112, and a control component 114. The second bent portion 112 is connected to the lower edge of the second surface 1023, and includes a third connecting portion 1121 and a fourth connecting portion 1122, with either the third connecting portion 1121 or the fourth connecting portion 1122 having a groove 1123.

[0039] In one embodiment, the third connecting portion 1121 is adjacent to the fourth connecting portion 1122.

[0040] In one embodiment, a control component 114 is disposed on a second surface 1023 and electrically connected to a plurality of solar cells 104 and light-emitting diodes 108, wherein turning on the control component 114 enables the power of the plurality of solar cells 104 to be transferred to the light-emitting diodes 108.

[0041] The solar photovoltaic module 100 of this utility model further includes a transformer 116, which is disposed on the second surface 1023.

[0042] In some embodiments, the solar photovoltaic module 100 further includes a plurality of bumps 118 disposed on the second surface 1023. The bumps 118 may be fire-retardant materials to protect the control component 114 and the transformer 116 from fire. In one embodiment, the bumps 118 are sound-insulating foam materials; when the solar photovoltaic module 100 is installed on a building wall, the sound-insulating foam material adheres to the building wall to block external noise from entering the room. In one embodiment, the substrate 102 further has a through-hole adjacent to the plurality of solar cells 104 and the control component 114, and the control component 114 is electrically connected to the plurality of solar cells 104 through the through-hole.

[0045] Example 2

[0046] Please refer to Figure 2(a), which shows a splicing diagram of two solar photovoltaic modules 200 and 202 according to an embodiment. Solar photovoltaic module 200 and another identical solar photovoltaic module 202 have the same structure. In some embodiments, the second surface 2041 of the substrate 204 of solar photovoltaic module 200 is adjacent to the first surface 2061 of the substrate 206 of another identical solar photovoltaic module 202. The connection between solar photovoltaic module 200 and the other identical solar photovoltaic module 202 can be achieved by engaging the groove 2082 of the fourth connecting portion 2081 of the second bending portion 208 of solar photovoltaic module 200 with the locking portion 2102 of the first connecting portion 2101 of the first bending portion 210 of the other identical solar photovoltaic module 202. It can be seen that the locking portion 2102 engages in the direction of the groove 2082 (as indicated by the arrow). Therefore, if solar photovoltaic module 200 and another solar photovoltaic module 202 are suspended on the wall of a building (not shown in the figure), the other solar photovoltaic module 202 is located to the lower right of solar photovoltaic module 200.

[0047] Please refer to Figure 2(b), which shows an embodiment of another solar photovoltaic module 202 fixed to the wall W. Further, after the two solar photovoltaic modules 200 and 202 are joined together, the other solar photovoltaic module 202 is fixed to the wall W by a fixing element 212. The fixing element 212 has an upper part 2121 and a lower part 2122. In some embodiments, the lower part 2122 has a hook shape and fits into the first connecting part 2101 of the first bend 210 of the other solar photovoltaic module 202. The fixing element 212 is secured to the wall W by screws 214 passing through the upper part 2121. When the lower part of the fixing element is fitted into the first connecting part 2101 and its upper part 2121 is locked to the wall W, after the two solar photovoltaic modules 200 and 202 are spliced ​​together, the upper part of the first connecting part 2101 of the first bend 210 of the other identical solar photovoltaic module 202 is covered by the fixing element 212, and the lower part 2122 seals the seam between the fourth connecting part 2081 and the first connecting part 2101. Therefore, in the event of rain, there is no seam for rainwater to pass through. On the other hand, when the upper part 2121 of the fixing element 212 is locked to the wall W, the fixing element 212 also provides tensile support for the other solar photovoltaic module 202.

Figure 3 On the wall of building B shown, the first solar photovoltaic module 302 and the second solar photovoltaic module 304 of the five solar photovoltaic modules need to be installed on the wall first. The third solar photovoltaic module 306 uses its first bending part 3061 to fit into the second bending parts 3021 and 3041 of the first solar photovoltaic module 302 and the second solar photovoltaic module 304. The fourth solar photovoltaic module 308 uses its first bending part 3081 to fit into the second bending part 3021 of the first solar photovoltaic module 302.
