The cross sectional representation of the double glazing photovoltaic module that Fig. 2 provides for the utility model embodiment scheme.
Among Fig. 1 and Fig. 2:
Embodiment
Core of the present utility model provides a kind of double glazing photovoltaic module, is used for saving the material of double glazing photovoltaic module and reducing its cost, can also make the double glazing photovoltaic module be convenient to maintenance.
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 1 and Fig. 2, the front view of the double glazing photovoltaic module that Fig. 1 provides for the utility model embodiment scheme; The cross sectional representation of the double glazing photovoltaic module that Fig. 2 provides for the utility model embodiment scheme.
In a kind of specific embodiment, a kind of double glazing photovoltaic module that this programme provides comprises:
The glued membrane 5 that is used for encapsulation solar battery sheet 4, glued membrane 5 are pasted on front glass 1 surface or glass 2 surfaces, back, and glued membrane 5 is positioned at cavity.
Because the double glazing photovoltaic module that the utility model scheme provides must have enough intensity as a kind of building material product, so, when front glass 1 is carried out selection with back glass 2, the general higher toughened glass of selection intensity.In addition, because solar battery sheet 5 needs the solar irradiation of sufficient intensity to generate electricity, and sunlight must shine on the solar battery sheet 5 through being positioned at outdoor front glass 1, so, front glass 1 needs to select light transmission material preferably, as the ultra-clear glasses of handling through tempering, the visible light transmittance rate of ultra-clear glasses surpasses 91%, can see through the sunlight of higher-strength for solar battery sheet 5 generatings; In order to make indoor strong illumination and the assurance assembly integral intensity avoided, back glass 2 can be selected reflective better and the higher toughened glass of intensity.
The seal group 3 of assembly arranges according to the standard of double glazing assembly in the present embodiment, to guarantee that this assembly has good sealing property, for example, the outer course of the seal group of general double glazing assembly adopts silicone adhesive or poly-sulphur glue to seal, road adopts butyl rubber to seal in it, and the form by double-layer seal is with guarantee that double glazing can be firm bonding and have good sealing property.
With the double glazing photovoltaic module contrast of routine, the assembly in the present embodiment has reduced the glued membrane 5 of one deck for encapsulation solar battery sheet 4, has also saved backboard.As shown in Figure 2, present embodiment carries out lamination with front glass 1, one deck glued membrane 5 with solar battery sheet 4 single faces successively, and the back side of solar battery sheet 4 is exposed in the cavity.Certainly, also glued membrane 5 can be pasted on the surface that is positioned at cavity of back glass 2, namely carry out lamination with solar battery sheet 4, glued membrane 5 with back glass 2 successively, arrange like this and be suitable for this assembly equally and carry out photovoltaic generation, in order to assemble with easy to maintenance, present embodiment is pasted on glued membrane 5 on the surface that is positioned at cavity of front glass 1.
The material that is used for the glued membrane 5 of encapsulation solar battery sheet 4 in the existing photovoltaic module is generally EVA or polyvinyl butyral resin (PVB), because the EVA glued membrane has the high grade of transparency, easily storage, low melting point and easy advantage such as mobile, and than PVB film better soundproof effect is arranged, therefore, present embodiment is chosen the EVA glued membrane and is encapsulated solar battery sheet 4.
In order to prevent the phenomenon of double glazing generation condensation or frosting, need the gas in the cavity to keep dry, so present embodiment is provided with drier 6 at cavity inside, drier 6 is inlayed usually and is arranged at cavity seal group 3 all around, absorbs the moisture of cavity inside with this.
Terminal box of the prior art is arranged in the insulating and sealing member, makes that the diode in the terminal box is difficult for dispelling the heat and being damaged, and is difficult for maintain and replace.Present embodiment is arranged at terminal box the outside of assembly, can make vitals such as diode be more prone to heat radiation like this, thereby reduced the spoilage of diode, and, when needs repair or replace, do not need to take apart back glass 2 and seal group 3, thereby made things convenient for the maintenance personal to operate.
In order to make assembly neat appearance more, usually terminal box is arranged at more hidden position.Owing to have spaces such as slit or groove usually between the back glass 2 between each assembly, so present embodiment takes full advantage of these narrow spaces, terminal box is arranged in the groove between the back glass 2 of two adjacent components, so just avoided terminal box that mixed and disorderly phenomenon is set, made the assembly outward appearance after the assembling cleaner and tidier.
The double glazing photovoltaic module that above-described embodiment provides has not only been saved material, has been reduced cost in the above-mentioned improvement that carry out on the basis of existing assembly in conjunction with the advantage of double glazing curtain wall and photovoltaic module, and makes it be convenient to maintenance more.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
