Abstract
The utility model discloses a crystalline silicon photovoltaic module which comprises low iron super-white tempered glass (1), an upper adhesive film (2), a battery piece (3), a lower adhesive film (4) and a backing plate (5), wherein the lower adhesive film (4) is smaller than the upper adhesive film (2) in size. According to the crystalline silicon photovoltaic module, the amount of adhesive films is reduced by 5% compared with a common module, cost of the module is reduced, and performance of the module is not influenced.
Description
Technical field
The utility model relates to a kind of crystal silicon photovoltaic assembly, belongs to photovoltaic module technical field.
Background technology
At present, the structure of crystal silicon component is: glass, upper glued membrane, cell piece, lower glued membrane, backboard, the size of conventional assembly is, glued membrane and backboard measure-alike is all greater than approximately 10 millimeters, glass, in whole assembly, the consumption with glued membrane is maximum especially, there are two kinds of wastes in this structure, one, and assembly glued membrane after lamination can overflow a part along glass edge, overflow partly cut throwing away, form waste; Its two, after lower glued membrane 4 is overlapping with upper glued membrane 2, be bonded together with backboard, form the blank of assembly, due to limit, portion does not have cell piece, so this overlapping of glued membrane also forms and waste.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of crystal silicon photovoltaic assembly, has reduced the use amount of glued membrane, has reduced the weight of assembly, has saved the cost of assembly.
For achieving the above object, the technical scheme that the utility model adopts is: crystal silicon photovoltaic assembly, its structure is followed successively by from top to bottom: low iron ultrawhite toughened glass, upper glued membrane, solar battery sheet, lower glued membrane, backboard, described lower glued membrane is close to solar battery sheet, and its size is than solar battery sheet limit minister 2～5mm.
Further, described upper glued membrane is identical with lower glued membrane material, is EVA, a kind of in HDPE, and thickness is between 0.40～0.60mm.
Further, the size of described lower glued membrane is than the little 10～20mm of the size of upper glued membrane.
The beneficial effects of the utility model are: the use amount of glued membrane having been reduced to 5%, saved the cost of assembly, also reduced the weight of assembly simultaneously, is the glued membrane that repeats stack due to what reduce, so the performance of assembly is unaffected.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model crystal silicon photovoltaic assembly.
In figure: 1, low iron ultrawhite toughened glass, 2, upper glued membrane, 3, solar battery sheet, 4, lower glued membrane, 5, backboard.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the structure of crystal silicon component is followed successively by from top to bottom: low iron ultrawhite toughened glass 1, upper glued membrane 2, solar battery sheet 3, lower glued membrane 4, backboard 5, described glued membrane is the copolymer of EVA(ethylene-vinyl acetate), HDPE(high density polyethylene (HDPE)) a kind of in, its thickness is between 0.40～0.60mm, the size of described lower glued membrane (4) is than the little 10～20mm of size of upper glued membrane (2), when assembly is manufactured, the size of lower glued membrane 4 is cut into than the length of cell piece group limit minister 2～5mm, but it should be noted that, when laying, the order of two-layer glued membrane can not be put upside down.
The use amount of glued membrane having been reduced to 5%, saved the cost of assembly, also reduced the weight of assembly simultaneously, is the glued membrane that repeats stack due to what reduce, so the performance of assembly is unaffected.
Claims (3)
1. a crystal silicon photovoltaic assembly, its structure is followed successively by from top to bottom: low iron ultrawhite toughened glass (1), upper glued membrane (2), solar battery sheet (3), lower glued membrane (4), backboard (5), is characterized in that: described lower glued membrane (4) is close to solar battery sheet (3), and size is than solar battery sheet (3) limit minister 2～5mm.
