Description

Technical Field

[0001] This utility model relates to the field of solar photovoltaic panel technology, and in particular to a flexible solar photovoltaic panel that can be spliced ​​together. Background Technology

[0002] With the continuous growth of global demand for renewable energy, solar photovoltaic technology, as an important representative of clean energy, has become increasingly popular. Among them, flexible solar photovoltaic panels, as an emerging technology product in the world's solar energy industry, have a series of unique characteristics and advantages. Flexible solar photovoltaic panels are solar panels made by laying resin-encapsulated amorphous silicon as the main photoelectric element layer on a base plate made of flexible material. This gives the photovoltaic panels the characteristics of being soft, lightweight and flexible, and can be adapted to be installed on various curved objects. Flexible solar photovoltaic panels can also be installed on flat surfaces, thereby improving the applicability of solar photovoltaic panels.

[0003] Flexible photovoltaic (PV) panels are thin, flexible, and bendable, easily adapting to various complex building surfaces and installation environments. However, the area of ​​a single flexible PV panel is limited, and in situations requiring large-area power generation, a single panel may not meet the demand. Therefore, it is necessary to splice and assemble individual flexible PV panels. Currently, the installation of flexible PV modules on the market mainly relies on back structural adhesive and double-sided foam tape bonding. However, since PV panels are used outdoors for extended periods and are exposed to wind, rain, and temperature changes, the back adhesive and foam tape are prone to aging and failure. This can lead to the flexible solar PV panels easily detaching from each other, affecting the stability of the solar PV panels. Therefore, corresponding improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a splicable flexible solar photovoltaic panel to solve the problem of unstable splicing of flexible solar photovoltaic panels mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a splicable flexible solar photovoltaic panel, comprising a panel body and rubber strips, with rubber strips connected to both sides of the panel body. The panel body includes a flexible substrate layer, a photoelectric conversion layer, and an encapsulation and protection layer. A photoelectric conversion layer is adhered to one side of the flexible substrate layer, and an encapsulation and protection layer is provided on the outer side of the photoelectric conversion layer and the flexible substrate layer. The flexible substrate layer is made of polyester, the photoelectric conversion layer is made of amorphous silicon, and the encapsulation and protection layer is made of polyolefin.

[0006] It also includes: a rubber strip with a connecting strip on the outside, and both ends of the connecting strip have a splicing hole with a rectangular cross section, and the rubber strip is provided with a splicing mechanism on the outside.

[0007] Preferably, the splicing mechanism includes a bidirectional hook block, which is fixed to a rubber strip on the right side of the main body of the plate. There are two bidirectional hook blocks, which are distributed vertically on the rubber strip. A reset spring is connected inside the bidirectional hook block, and a locking block is connected to one side of each bidirectional hook block.

[0008] Preferably, both sides of the splicing socket are connected to a limiting bracket, and one side of the limiting bracket is provided with a protrusion. The limiting bracket is connected to the limiting bracket by a locking block and a bidirectional hook block.

[0009] Preferably, a heat insulation board is connected to the back of the main body of the plate, and a support component is provided inside the heat insulation board.

[0010] Preferably, the support component includes transverse support strips and longitudinal support strips uniformly disposed inside the heat insulation board. Multiple sets of transverse support strips and longitudinal support strips are disposed in the heat insulation board, and the multiple sets of transverse support strips and longitudinal support strips are distributed in a crisscross pattern to form a mesh structure.

[0011] Preferably, the heat insulation board is filled with heat insulation cotton, and the mesh formed by the transverse support strips and the longitudinal support strips covers the heat insulation cotton.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the splicable flexible solar photovoltaic panel can not only be easily assembled and spliced ​​firmly to meet different usage needs, but also has a better heat insulation effect to improve the photoelectric conversion efficiency;

[0013] Insert the bidirectional hook into the splicing hole. During this process, the forked ends of the bidirectional hooks approach each other, and the return spring is compressed. When the bidirectional hooks are fully inserted, the return spring returns to its original position, which pushes the forked ends of the bidirectional hooks back to their original position and engages with the locking block to achieve the splicing of multiple panels. The operation is convenient and significantly increases the power generation of the entire photovoltaic power generation system. Under good lighting conditions, more panels can capture more light energy and convert it into electrical energy, thereby meeting greater power demand. The overall operation is simple and replaces traditional adhesive splicing, making it more secure.

[0014] By installing a heat insulation board on the back of the main body of the plate, the temperature of the main body of the plate can be kept stable during use, avoiding a decrease in the power generation efficiency of the main body of the plate due to excessive temperature. Heat insulation cotton is filled into the heat insulation board to further enhance the heat insulation effect and prevent heat from accumulating on the main body of the plate. Multiple sets of horizontal and vertical support strips are set in the heat insulation board to form a mesh structure, which can provide internal support for the heat insulation board and help enhance the overall stability of the heat insulation board.
