Description

High altitude localities photovoltaic module
Technical field
This utility model relates to photovoltaic field, particularly to a kind of high altitude localities photovoltaic module.
Background technology
Along with traditional fossil energy worsening shortages, the development and application of regenerative resource increasingly receives the concern of people.As important regenerative resource, solar energy power generating is gathered around and is held out broad prospects.The high altitude localities sunshine-durations such as plateau are long, and air is thin, air cleaner, and solar radiation is strong, and day and night temperature is relatively big, has abundant solar energy resources, possesses the good condition utilizing photovoltaic generation.Due to the conventional photovoltaic assembly deficiency to purple extraradial protective capacities, it is difficult to ensure its normal power generation within quality guarantee period in highlands.
In high altitude localities, owing to intensity of sunshine is big, especially illumination middle-ultraviolet lamp intensity is better than in low altitude areas such as Plains, and conventional photovoltaic assemblies easily occurs that the situations such as aging, dusty wind weather and bigger day and night temperature can cause photovoltaic junction box to ftracture.Additionally, the longer snowfall time causes that assembly surface accumulated snow also can affect the generated energy that assembly is annual.Therefore, general components can not meet the requirement of special climate condition.The photovoltaic module possessing special nature for the research and development of varying environment condition will be trend and the direction of future assemblies development.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of photovoltaic module being suitable for high altitude localities, it is to avoid the problems such as UV-induced material aging, component failures.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of high altitude localities photovoltaic module, including the glass stacked gradually from top to bottom, the first EVA layer, solar battery sheet, the second EVA layer and backboard, described second EVA layer is uvioresistant height cut-off EVA layer.
Preferably, described glass is the anti-reflection coated glass that surface-coated has nonpolluting coating.
Preferably, the upper and lower surface of described backboard is coated with fluorine-containing layer.
Preferably, described photovoltaic module also includes the rosette being arranged on described backboard lower surface, and the rated current of described rosette is 13 ~ 17A, and rated voltage is 1200 ~ 1800V.
It is highly preferred that the degree of protection of described rosette be IP68 and more than.
Preferably, described photovoltaic module also includes aluminum frame, and described glass, the first EVA layer, solar battery sheet, the second EVA layer and backboard are installed in described aluminum frame.
Preferably, described first EVA layer is high EVA layer thoroughly.
This utility model adopts technique scheme, have the advantage that compared to existing technology suitable in high altitude localitiess such as plateaus, this assembly permanently effective can avoid the problems such as UV-induced material aging, component failures, it is possible to makes full use of the illumination resource that highlands is abundant.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of photovoltaic module of the present utility model.
In above-mentioned accompanying drawing:
1, glass;2, the first EVA layer;3, cell piece;4, the second EVA layer;5, backboard;6, rosette;7, aluminum frame.
Detailed description of the invention
Advantage of the present utility model and feature below in conjunction with accompanying drawing, preferred embodiment of the present utility model be described in detail, so that can be easier to be understood by those skilled in the art.That addresses in this utility model upper and lower be usual viewing angle according to those skilled in the art and define for convenient narration, does not limit concrete direction, e.g., corresponds respectively to the upper side and lower side of paper in Fig. 1.
Accompanying drawing 1 show a kind of solar photovoltaic assembly of the present utility model, and it is applicable to the high altitude localitiess such as plateau.With reference to shown in accompanying drawing 1, including glass the 1, first EVA layer 2 stacked gradually from top to bottom, solar battery sheet the 3, second EVA layer 4 and backboard 5.Wherein, glass 1 has the anti-reflection coated glass 1 of nonpolluting coating for surface-coated, and above-mentioned glass 1, by making at the antifouling reflection reducing coating of surface-coated, has the effect preventing polluting, can effectively prevent snow cover and maximally utilise solar radiation.The high EVA layer thoroughly that first EVA layer 2 is made for adopting high EVA adhesive film thoroughly.Cell piece 3 is multiple and is sequentially connected in series.Second EVA layer 4 is the uvioresistant height cut-off EVA layer adopting the EVA adhesive film being added with ultraviolet (UV) resistant agent to make, and has the function of ultraviolet-cutoff.The upper and lower surface of backboard 5 is coated with fluorine-containing layer, is specially PTFE(politef) coating.Adopt the higher EVA of anti-ultraviolet ageing ability and backboard 5, it is to avoid the generation of material aging and component failures, promote the weatherability that assembly is overall.
Photovoltaic module also includes the rosette 6 being arranged on backboard 5 lower surface.The rated current of rosette 6 is 13 ~ 17A, and rated voltage is 1200 ~ 1800V, degree of protection be IP68 and more than.The rated current of current general components rosette 6 is generally 12.8A, and rated voltage is generally 1000V, and degree of protection is IP65 to IP67.This utility model adopts the rosette 6 of bigger rated current (e.g., 15A), bigger rated voltage (e.g., 1500V) and more high-protection level (e.g., IP68), improves the assembly reliability when special climate, it is ensured that its long-time normal operation.Herein, degree of protection is according to IP(INGRESSPROTECTION) degree of protection system.
