Weak with adhesive property, the absorption impact property ratio PVB of glass, the safety used in building is insufficient.
Another is tempered glass+PVB glue film+solar battery+PVB glue film+tempered glass structure, using laminating machine
Carry out preforming, it is relatively conventional at present to reuse autoclave cured technique, but the delamination of actual process process, bubble, fragment, displacement
It is low etc. yield rate is caused.And it is not yet mature to be directly entered the one-time formed technology of autoclave.
It is limited to material selection and realizes process with technique, conventional double glass crystal silicon components have the following deficiencies: (1) due to using
Double glazing lamination, laminated compenent is usually plate, and style is single, is difficult to produce cambered (or radian is slightly larger)
Double glass crystal silicon components；(2) be not suitable for curved surface installation, need radian design small as far as possible when encountering curved surface installation, mostly use muti-piece group
The mode of part angle splice realizes that installation difficulty is big, and overall aesthetic degree is influenced by very big；(3) installation needs additional support
Structure, system cost increase；(4) it is limited to lamination size, monolithic large-size componentsization are realized difficult.
There are some technical solutions to propose to substitute tempered glass by using high light transmission film, transparent back panel, but in reality
In application process, since these high light transmission film, transparent back panels are mostly only with the glue films such as EVA, POE, the so light after encapsulation
Component is lied prostrate, is unable to satisfy photovoltaic industry technical standard at all in the performances such as shock resistance, fire prevention, weatherability, thus existing is not had also
There is suitable technical solution to replace existing double-sided glass crystal silicon component.
Summary of the invention
In view of this, having and existing solar double-glass assemblies phase the purpose of this utility model is to provide a kind of photovoltaic module
With attractive, decorative effect under the premise of, while the obvious weight for alleviating photovoltaic module, installation is simple, more holds than solar double-glass assemblies
It easily realizes the design of radian shape, effectively avoids photovoltaic module crack, can also flexibly realize monolithic large scale in the fabrication process
Componentization is provided simultaneously with the feature that long-term reliability is high, the service life is long, security performance is high, is particularly suitable for curtain wall, lighting roof, agricultural
The buildings such as greenhouse, glass sunlight house, carport, Waiting Lounge use.
