Description

A kind of double glass photovoltaic module roof boarding

Technical field

This utility model relates to photovoltaic module technical field, a kind of double glass photovoltaic module roof boardings.

Background technology

Solar energy is a kind of inexhaustible energy.Since entering 21 century, photovoltaic industry achieves development at full speed.On the premise of developing rapidly, the quality of product becomes to be even more important, and needs especially to obtain sound assurance, allows user relieved use.

Common roof boarding photovoltaic module has two classes, a class to be front glass/polymer back board modules, another kind of be before and after be all glass.During using, at single glass assembly behind i.e. polymer backboard, electric equipment and power line are installed, there is hidden danger of catching fire, have impact on house fireproof grade；The back side of solar double-glass assemblies uses safety glass, can prevent fires, improve the reliability of assembly, but the structure of current solar double-glass assemblies is safety glass/EVA adhesive film/solar battery group/EVA adhesive film/glass, the Chinese of EVA adhesive film is ethene-vinyl acetate copolymer, it it is the low softening point binding material of a kind of flexibility, the manufacture of photovoltaic module use at most, technology is the most ripe, but the greatest problem of EVA material to be weatherability poor, long-term outdoor uses material easily to decompose jaundice, affect the power generation performance of assembly, EVA temperature under the irradiation of sunlight easily raises simultaneously, easily combustion explosion.

Therefore, the photovoltaic module roof boarding how providing a kind of weatherability strong is the problem that those skilled in the art need solution badly.

Utility model content

In view of this, this utility model provides a kind of double glass photovoltaic module roof boarding, not only increases the weatherability of overall double glass photovoltaic module, and extends the service life of assembly.

To achieve these goals, the following technical scheme of this utility model offer:

A kind of double glass photovoltaic module roof boarding, is disposed with sensitive surface safety glass including: the double glass photovoltaic module of body, PVB composite membrane, solar battery group, PVB are combined notacoria and back side safety glass from top to bottom.

Preferably, in the double glass photovoltaic module roof boarding of above-mentioned one, described PVB composite membrane is arranged on described sensitive surface safety glass by the way of laying, and the specification of the specification of described PVB composite membrane and described sensitive surface safety glass is mutually matched.

Preferably, in the double glass photovoltaic module roof boarding of above-mentioned one, described PVB is combined notacoria and is arranged in described solar battery group by the way of laying, and the specification of the described PVB specification and described solar battery group that are combined notacoria is mutually matched.

Preferably, in the double glass photovoltaic module roof boarding of above-mentioned one, described sensitive surface safety glass, described PVB composite membrane, described solar battery group, described PVB are combined notacoria, described back side safety glass all uses laminate adhesive mode to combine closely.

Understand via above-mentioned technical scheme, compared with prior art, this utility model is open provides a kind of double glass photovoltaic module roof boarding, the PVB resin that weatherability is strong is used to replace traditional EVA adhesive film, not only increase the weatherability of solar double-glass assemblies, and life-time service assembly will not occur xanthochromia out of doors, extend the service life of assembly；PVB resin Chinese is polyvinyl butyral resin, is a kind of adhesive, is widely used in glass processing, the EVA adhesive film produced relative to photovoltaic module, and PVB glued membrane has long-term reliability, weatherability, color inhibition, safety height；Owing to PVB film softening point is high, directly use in solar double-glass assemblies produces and easily cause the increase of battery fragment, this utility model uses compound PVB film, while keeping PVB weatherability, high printing opacity advantage, suitably reduce softening point, there is the compliance similar with EVA adhesive film, reduce that the battery of solar double-glass assemblies is hidden to be split.

Therefore, this utility model is a kind of to integrate that weatherability is strong, safety is high, double glass photovoltaic module roof boardings of color inhibition, the multiple advantage of length in service life.

Accompanying drawing explanation

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only embodiment of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to the accompanying drawing provided.

Fig. 1 accompanying drawing is structural representation of the present utility model.

In FIG:

1 for sensitive surface safety glass, 2 for PVB composite membrane, 3 for solar battery group, 4 for PVB be combined notacoria, 5 be back side safety glass.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
