Description

A kind of self-cleaning type solar photovoltaic assembly

Technical field

This utility model relates to solar photovoltaic assembly field, particularly relates to a kind of self-cleaning type solar photovoltaic assembly.

Background technology

In recent years, along with day by day highlighting of energy crisis, solar energy is utilized to carry out generating electricity and become the focus that industry is paid close attention to and studied. Solar electrical energy generation is divided into photo-thermal power generation and photovoltaic generation, usually said solar electrical energy generation to refer to solar energy power generating, is called for short " photoelectricity ". Photovoltaic generation is utilize the photovoltaic effect of interface and luminous energy is directly translated into a kind of technology of electric energy; its key element is solaode; solaode carries out packaging protection after series connection can form large-area solar photovoltaic assembly, then coordinates the parts such as upper power controller to be the formation of photovoltaic generating system.

For solar photovoltaic assembly, maximum problem is not wind-powered electricity generation thunderstorm, but dust. Especially backland photovoltaic module displays, and dust can cover in element panels, produces electrostatic, and the ability that also can reduce assembly absorbs and conversion efficiency.

In addition assembly backboard composition and EVA belong to macromolecular material, and ultraviolet can cause material aging, and the material after aging there will be the problems such as jaundice, degraded, be full of cracks, has a strong impact on assembly generated energy, life-span, even with safety.

Utility model content

This utility model is mainly solving the technical problems that provide a kind of self-cleaning type solar photovoltaic assembly, can effectively absorb ultraviolet, slow down backboard and EVA glue is aging, there is nano self-cleaning function simultaneously, the service life of assembly can be extended, and improve the electricity conversion of assembly.

For solving above-mentioned technical problem, the technical scheme that this utility model adopts is: provide a kind of self-cleaning type solar photovoltaic assembly, including: high printing opacity toughened glass panel, photovoltaic module body, encapsulation framework, described photovoltaic module body includes from top to bottom successively: an EVA glue-line, solaode string, 2nd EVA glue-line, TPT backboard, on the outer surface of described high printing opacity toughened glass panel, plating is with nano titanium dioxide film, described encapsulation framework is the almag framework of upper end open, it is equipped with antidetonation silica gel plate between described almag framework and TPT backboard.

In one preferred embodiment of this utility model, the thickness of described nano titanium dioxide film is 40-60nm.

In one preferred embodiment of this utility model, the thickness of described high printing opacity safety glass is 2-4mm, its light transmittance >=95%.

In one preferred embodiment of this utility model, the thickness of described antidetonation silica gel plate is 2-5mm.

The beneficial effects of the utility model are: this utility model simple in construction, in the plating of high printing opacity toughened glass panel outer surface with nano titanium dioxide film, can effectively absorb ultraviolet, slow down TPT backboard and EVA glue-line is aging, there is self-cleaning function simultaneously, under this external TPT backboard, be equipped with antidetonation silica gel plate, it is avoided that solaode string is caused damage by vibrations, therefore this utility model assembly is by optimizing its overall structure, it is possible to extends its service life, and improves its electricity conversion.
