Abstract
The utility model discloses a solar cell module, which comprises a back plate, an EVA (ethylene vinyl acetate) layer, a battery string, an EVA layer and tempered glass which are sequentially stacked. The area of the back plate is larger than or equal to the area of one EVA layer, the area of the EVA layer is larger than or equal to the area of the tempered glass, and the area of the other EVA layer is larger than or equal to the area of the battery string. Two same EVA layers are used when the solar cell module is packaged and mainly used for adhering a battery slice, the glass and the back plate together, so that packaging effects are achieved. A current common battery slice of the solar cell module has certain distance away from the glass edge, namely the total area of the battery slice is smaller than the area of the glass slice, and one of the EVA layer is diminished to be smaller than the tempered glass and larger than the battery string so as to cover the battery slice, raw material consumption and cost of the solar cell module are reduced. Simultaneously, EVA adhesives overflowed after lamination can be decreased, so that quality problems such as occurrence of adhesive pits and the like are avoided and repair rate is decreased.
Description
Technical field
The utility model relates to a kind of solar module.
Background technology
The package fabrication process of present solar module mainly is: each lining is with EVA (ethene-vinyl acetate copolymer) film on the positive and negative two sides of solar cell string; In the encapsulation process; Under vacuum condition, be heated to certain temperature; The fusing of EVA layer solidified with the reduction of temperature, thereby battery is closely fixing; Gluing seals or seals with adhesive tape at the edge of assembly backboard, toughened glass then, adds frame at last.In view of size; Now the general size of encapsulating material is backboard >=EVA >=glass, and general thinking such packaging effect is better, but this packaged type need consume more raw material; Can't save raw material; Increased the material cost of solar module, simultaneously the unnecessary EVA sizing material of this packaged type overflows easily to cause hindering and installs, and makes that encapsulation is bad and causes product to reprocess.
Summary of the invention
To the deficiency of prior art, the technical problem that the utility model will solve provides a kind of solar module of saving raw material and being convenient to encapsulate.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of solar module; It comprises backboard, EVA layer, battery strings, EVA layer, the toughened glass that is cascading, the area of backboard area >=one of them EVA layer >=toughened glass area>area >=battery strings area of another EVA layer.
As the improvement of such scheme, be that sunlight is not had the EVA layer that ends than the EVA layer of small size.
The beneficial effect of the utility model is: two the same EVA that will use during owing to the solar module encapsulation, the main effect of EVA is that battery sheet, glass, backboard are bonded together, thereby reaches the effect of encapsulation.At present solar module battery sheet commonly used all has certain distance apart from glass edge; Be the area of the gross area of battery sheet less than sheet glass; Therefore EVA size decreases wherein less than the size of toughened glass and greater than the size of battery strings, makes it can the clad battery sheet; Can reduce wherein employed raw-material consumption of solar module, thereby reduce the cost of solar module; Simultaneously can also reduce the EVA glue that overflows behind the lamination, thereby avoid solar module quality problems such as Jiao Keng to occur, reduce the solar components repair rate, improve its product qualified rate.
Description of drawings
Fig. 1 is the structural representation of first embodiment of the utility model solar module.
Fig. 2 is the structural representation of second embodiment of the utility model solar module.
Embodiment
Further specify the embodiment of the utility model below in conjunction with accompanying drawing.
Like Fig. 1, shown in Figure 2; A kind of solar module of the utility model; It comprises backboard 10, EVA layer 12, battery strings 15, EVA layer 12, the toughened glass 18 that is cascading, the area of backboard area >=one of them EVA layer >=toughened glass area>area >=battery strings area of another EVA layer.
Because two the same EVA that will use during the solar module encapsulation, the main effect of EVA is that battery sheet 15, toughened glass 18, backboard 10 are bonded together, thereby reaches the effect of encapsulation.At present the battery sheet 15 of solar module commonly used all has certain distance apart from glass edge; Be the area of the gross area of battery sheet 15 less than sheet glass; Therefore EVA size decreases wherein less than the size of toughened glass and greater than the size of battery strings, makes it can the clad battery sheet; Can reduce wherein employed raw-material consumption of solar module, thereby reduce the cost of solar module; Simultaneously can also reduce the EVA glue that overflows behind the lamination, thereby avoid solar module quality problems such as Jiao Keng to occur, reduce the solar components repair rate, improve its product qualified rate.EVA resin wherein is an ethylene-vinyl acetate copolymer, and the battery sheet is battery strings again, is the sheet cell combination body that is formed by a plurality of battery cell serial connections.
More preferably, the EVA layer than small size is that sunlight is not had the EVA layer that ends.If that adopt is xenogenesis EVA, consider the weatherability of encapsulating material, the EVA of size decreases is not for preferably to have the EVA that ends to sunlight, and it is without hindrance that sunlight is penetrated fully, is convenient to better absorb solar energy, improves the efficient of solar module.
The above disclosed preferred embodiment that is merely the utility model can not limit the interest field of the utility model certainly with this, so according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
Claims (2)
1. solar module; It is characterized in that: comprise the backboard, EVA layer, battery strings, EVA layer, the toughened glass that are cascading, the area of backboard area >=one of them EVA layer >=toughened glass area the area >=battery strings area of another EVA layer.
2. solar module according to claim 1 is characterized in that: the EVA layer than small size is that sunlight is not had the EVA layer that ends.
