Description
Technical field
The present invention relates to solar energy power generating apparatus field, particularly relate to a kind of high reliability solar photovoltaic assembly.
Background technology
Photovoltaic module (being also solar panel) is the core in solar power system, is also most important part in solar power system, and its effect converts solar energy into electrical energy, or is sent in storage battery and stores, or promotes loaded work piece.
What solar cell power generation utilized is there is photovoltaic effect when the semi-conducting materials such as silicon are subject to solar radiation, directly solar radiation is converted to electric energy.This principle means that silicon wafer wants maximum magnitude to absorb solar irradiation, and therefore as unique barrier of silicon wafer and glass outer, EVA adhesive film needs possess very excellent light transmittance, and this characteristic has gain effect to the output of cell panel simultaneously.In addition, in structure composition, EVA adhesive film carries the cementation between silicon wafer, upper strata protective material glass, lower floor backboard three.In sum, EVA adhesive film not only plays encapsulation and cementation, and the quality of its light transmittance to solar cell plays vital effect.
At present, it is that VA content is low that EVA adhesive film compares distinct issues, and light transmittance is low, and rear EVA adhesive film of long duration can be turned to be yellow simultaneously, affects the light transmittance of self, thus greatly reduces the electricity conversion of solar photovoltaic assembly.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of high reliability solar photovoltaic assembly, adopts the encapsulation of high-performance EVA adhesive film, greatly can improve the electric transformation efficiency of assembly and can extend useful life of assembly.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of high reliability solar photovoltaic assembly, comprise the panel, the first EVA adhesive film layer, solar battery group, the second EVA adhesive film layer and the backboard that stack gradually from top to bottom together, described panel layer adopts the one in glass, light panel or fiber optic fiber, described first EVA adhesive film layer and the second EVA adhesive film layer all adopt high-performance EVA adhesive film, its VA content is 45-55%, and at least one surface recombination of described high-performance EVA adhesive film has waterproofing membrane.
In a preferred embodiment of the present invention, described solar battery group is welded by monocrystaline silicon solar cell sheet.
In a preferred embodiment of the present invention, the VA content of described high-performance EVA adhesive film is 48%.
In a preferred embodiment of the present invention, described backboard adopts TPT film.
The invention has the beneficial effects as follows: the present invention adopts high-performance EVA adhesive film to encapsulate, its VA content is high, prolonged non-yellowing, effectively can improve the optoelectronic transformation efficiency of assembly; This EVA film is compounded with waterproof film layer simultaneously, can improve the protection against the tide of photovoltaic module, water resistance, thus effectively improves the useful life of assembly.
