Problems solved by technology

[0004] However, in the existing production process, due to the small thickness of the backboard, when the laid laminate is transmitted on the transmission line, the sharp objects on the transmission line will cause scratches to the backplane, and the trimmers will scratch the backboard during the editing process. The backplane will also cause damage, which will affect the barrier performance of the backplane. The infiltration of water vapor will directly lead to corrosion of the internal circuit of the battery panel and shorten the life of the components. In addition, the frame of the aluminum profile is not only prone to bending, twisting and Intuitive defects such as screwing, deformation, slag inclusion, etc., and the problem of "adsorbed particles" that cannot be recognized visually or tactilely, the pass rate of the aluminum profile frame is maintained at a maximum of about 95%

Embodiment 1

[0064] like Figure 1-4 As shown, Example 1 SMC monolithic photovoltaic module includes an open groove 1 made of SMC material, and the bottom plate 1a of the open groove 1 is sequentially vacuum laminated and bonded to be provided with a first sealing adhesive layer 2, a battery sheet 3, a second Two sealing adhesive layers 4, light-transmitting panels 5; the bottom plate of the open slot 1 is provided with a through hole 7 through which the bus bar lead-out line 6 of the battery sheet 3 passes, and the open slot 1 is provided with a bus bar lead-out line 6 connected to the junction box 8, the first sealing adhesive layer 2, the battery sheet 3, the second sealing adhesive layer 4, the outer edge of the light-transmitting panel 5 and the side wall 1b of the open groove 1, and the bus bar lead-out wire 6 A filling glue 13 is sealed between the through hole 7 and the through hole 7 .

[0065] The open slot in embodiment 1 is composed of a base plate and a frame-shaped side wall...

Embodiment 2

[0073] like Figure 2-8 As shown, the difference between embodiment 2 and embodiment 1 is that the outer surface of the bottom plate of the open groove 1 is provided with reinforcing ribs 9 ; the outer surface of the bottom plate of the open groove is also provided with frame-shaped protrusions 10 . The ribs 9 are grid-shaped.

[0074] The frame-shaped protrusion 10 is opposite to the side wall of the open groove 1 on the surface of the bottom plate 1a, that is, the frame-shaped protrusion 10 extends from the side wall 1b of the open groove to the back of the bottom plate.

[0075] The reinforcing rib 9 and the frame-shaped protrusion 10 can be separately arranged on the open groove 1 .

[0076] In Embodiment 2, the cross section of the side wall 1b of the open groove is in the shape of a right-angled trapezoid, and the inclined side of the side wall 1b is located at the inner edge of the frame-shaped side wall.

[0077] The junction box is arranged on the outer surface of t...

Embodiment 3

[0079] like Figure 9 As shown, Embodiment 3 is based on Embodiment 2. The surface of the component is embedded with a connector 11, which is used to connect the SMC integral photovoltaic module to the base surface, and the connector 11 is embedded in the open groove. on the side wall. Specifically, the pre-embedded connectors are nuts.

Abstract

The invention belongs to the field of solar cells, and specifically relates to an SMC integrated photovoltaic module, a manufacturing method and an application. The invention discloses an SMC integrated photovoltaic module comprising an open groove made of an SMC material, a first sealing adhesive layer, a battery sheet, a second sealing adhesive layer and a light transmitting panel are arranged on a bottom plate of the open groove in sequence by vacuum lamination and adhesion; a through hole for enabling a bus bar outgoing line of the battery sheet to pass through is formed in the bottom plate of the open groove, a junction box connected with the bus bar outgoing line is arranged at the outside of the open groove, and fillers are hermetically arranged among the first sealing adhesive layer, the battery sheet, the second sealing adhesive layer, the outer edge of the light transmitting panel and the side wall of the open groove, and between the bus bar outgoing line and the through hole. The introduction of the open groove made of the SMC material is inductive to reducing the defect rate of components and modules such as a backplane frame. The invention further discloses a manufacturing method and an application of the SMC integrated photovoltaic module.

Description

technical field [0001] The invention belongs to the field of solar cells, and in particular relates to an SMC integral photovoltaic module, a manufacturing method and an application thereof. Background technique [0002] The solar cell module in the prior art comprises sequentially along the light incident direction: a laminated assembly, a frame, a junction box, and a filler. The laminated assembly includes a laminated packaged tempered glass, an EVA layer, a battery sheet, an EVA layer, and a back sheet. [0003] The back sheet is located on the back of the solar cell panel, which protects and supports the cells, and has reliable insulation, water resistance, and aging resistance. The role of the frame is to protect the laminate and at the same time facilitate the installation of the photovoltaic panels. Common materials for the frame are aluminum alloy, stainless steel and reinforced plastic. The advantages of the aluminum alloy frame are: light weight, corrosion resist...
