Description

Technical Field

[0001] The present application belongs to the technical field of photovoltaic systems, and specifically relates to an assembled photovoltaic integrated panel and a photovoltaic system. Background Art

[0002] With the gradual depletion of global fossil energy, energy transformation is imperative, and photovoltaic building integration is one of the effective ways. Photovoltaic building integration generally includes BIPV (Building Integrated Photovoltaic) and BAPV (Building Attached Photovoltaic). BIPV refers to a solar photovoltaic power generation system that is designed, constructed and installed at the same time as the building and forms a perfect combination with the building. It has both the function of power generation and the functions of building components and building materials. BAPV refers to a solar photovoltaic power generation system attached to a building. Its main function is to generate electricity. It does not conflict with the function of the building and does not destroy or weaken the function of the original building.

[0003] In the prior art, BAPV installs TPO (thermoplastic polyolefin) supports by drilling holes in the metal roof, and performs hot air welding on the TPO supports one by one to achieve waterproofing, and then installs rails on the TPO supports to connect photovoltaic modules. BIPV combines the TPO strips on both sides of the short side of the flexible photovoltaic module and the TPO coiled material composited on the metal roof by hot air welding.

[0004] At present, most fusion tile solutions on the market use BAPV solutions, which usually require drilling holes and destroying the original roof in actual applications, and the process is cumbersome and there is a risk of failure. The products of BIPV solutions are not mature enough and have major problems in terms of safety and reliability. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0024] The assembled photovoltaic integrated panel and photovoltaic system provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0025] See also Figures 1 to 7 , an assembled photovoltaic integrated panel, comprising a fusion tile 10 and at least one photovoltaic module 20; wherein the fusion tile 10 comprises a body 11 and a waterproof layer 12, the waterproof layer 12 is arranged on a side of the body 11 facing the photovoltaic module 20, and the waterproof layer 12 is adhered to the profile of the body 11; the body 11 comprises a plane portion 113 and two first support portions 111 arranged opposite to each other along a second direction Y, the plane portion 113 is sandwiched between the two first support portions 111 along the second direction Y and is respectively connected to the two first support portions 111, the first support portion 111 protrudes from the plane portion 113 in a direction close to the photovoltaic module 20, the first support portion 111 extends along the first direction X, and the backlight surface of the photovoltaic module 20 is adhered to the waterproof layer 12; wherein the first direction X is the length direction of the assembled photovoltaic integrated panel, and the second direction Y is the width direction of the assembled photovoltaic integrated panel.

[0026] In the embodiment of the present application, the fusion tile 10 is used to support the photovoltaic module 20 on the one hand, and the fusion tile 10 also plays the role of the roof of the building on the other hand. Since the backlight surface of the photovoltaic module 20 can be directly bonded to the fusion tile 10, and since the photovoltaic module 20 is bonded to the fusion tile 10, before the assembled photovoltaic integrated panel leaves the factory, the fusion tile 10 and the photovoltaic module 20 are bonded and connected by adhesives, and then the assembled photovoltaic integrated panel is transported to the construction site and installed in the building, which has the beneficial effects of shortening the time for installing the assembled photovoltaic integrated panel at the construction site, simplifying the installation process, and improving the construction efficiency. In addition, the process of bonding the photovoltaic module 20 to the fusion tile 10 can be carried out in a workshop environment that is more stable than the construction environment, and the bonding quality is significantly improved by the influence of the environment.

[0027] Furthermore, the main body 11 is made of a material with a certain supporting strength to provide support for the photovoltaic module 20 and form a roof for the building. The waterproof layer 12 is provided to prevent rainwater in the natural environment from flowing into the building. The waterproof layer 12 is provided on one side of the main body 11 close to the photovoltaic module 20, and the photovoltaic module 20, the waterproof layer 12 and the main body 11 are provided in sequence. The waterproof layer 12 is attached to the profile structure of the main body 11, that is, the profile of the waterproof layer 12 is consistent with that of the main body 11. In actual applications, the waterproof layer 12 attached to the profile of the main body 11 makes the gap between the main body 11 and the waterproof layer 12 smaller, which is convenient for the waterproof layer 12 to protect the profile and also convenient for the photovoltaic module 20 to be connected to the fusion tile 10. The main body 11 includes two first support portions 111 and a planar portion 113. The two first support portions 111 arranged opposite to each other along the second direction Y sandwich the planar portion 113 in the middle, and both first support portions 111 protrude from the planar portion 113. The two first support portions 111 provide support for the photovoltaic component 20, thereby improving the supporting stability of the main body 11 for the photovoltaic component 20.

[0028] It should be noted that the waterproof layer 12 may be a TPO waterproof membrane, and the waterproof layer 12 may be connected to the body 11 by heat pressing.

[0029] Furthermore, the photovoltaic assembly 20 may be bonded to the first support portion 111 by means of structural adhesive. The structural adhesive may be bonded by applying the adhesive throughout the entire length or in sections, and this embodiment does not impose any limitation on this.

[0030] Furthermore, when problems such as glue overflow occur during the bonding process, they can be handled directly in the workshop, making it easier to repair the assembled photovoltaic integrated panel.

[0031] It should also be noted that the photovoltaic components 20 in the prefabricated photovoltaic integrated panels cover part of the fused tiles 10. During the actual installation process, multiple prefabricated photovoltaic integrated panels are interconnected to form the roof of the building. The part of the fused tiles 10 that is not covered by the photovoltaic components 20 can be overlapped with the adjacent prefabricated photovoltaic integrated panels to form the roof of the building.

In practical applications, the second support portion 112 is provided to assist the first support portion 111 in providing support for the photovoltaic assembly 20. Specifically, when the width of the photovoltaic assembly 20 along the second direction Y is relatively wide, the two first support portions 111 provided at both ends of the plane portion 113 along the second direction Y have a relatively small support span for the photovoltaic assembly 20, and the provision of the support portion can support the photovoltaic assembly 20 from the middle of the photovoltaic assembly 20, which has the beneficial effect of improving the support stability of the photovoltaic assembly 20 by the body 11.

The two overlapping portions 1141 arranged opposite to each other along the first direction X sandwich the planar portion 113 in the middle, and the two overlapping portions 114 both protrude from the planar portion 113. The setting of the two overlapping portions 114 is used to increase the supporting strength of the main body 11 itself along the second direction Y, thereby improving the supporting stability of the main body 11 for the photovoltaic component 20.

[0037] In actual applications, when two assembled photovoltaic integrated panels are adjacent and arranged along the second direction Y, the overlapping portion 114 of one assembled photovoltaic integrated panel can be overlapped and connected with the overlapping portion of another assembled photovoltaic integrated panel 113.
