Abstract
The utility model discloses a solar photovoltaic module, and belongs to the technical field of photovoltaic batteries. The solar photovoltaic module comprises a battery pack, a back panel and a battery encapsulating layer, the back panel and the battery encapsulation layer are stacked and pressed on two sides of the battery pack respectively, EVA coating layers are arranged between the backboard and the battery pack and between the battery encapsulation layer and the battery pack, and the battery encapsulation layer is made of fiber-reinforced composite plastics. The solar photovoltaic module is light in weight, has a strong anti-collision capability, and is not easy to crack after collision.
Description
Technical field
The utility model relates to a kind of solar photovoltaic assembly, belongs to the photovoltaic cell technical field.
Background technology
At present, solar cell power generation can not discharge carbon dioxide or produce the gas harmful to greenhouse effect, and also noiselessness is a kind of net energy source, with environment good compatibility is arranged.Solar components is a kind of building material that integrates generating, sound insulation, heat insulation, safety, decoration functions, has demonstrated fully intellectuality and the human features of building.But the photovoltaic module weight under the prior art is heavier, and impact resistant capability a little less than, in afterwards easily explosion of bump.
Summary of the invention
Technical problem to be solved of the present utility model is the defective that overcomes prior art, provides that a kind of lightweight, impact resistant capability is strong, is not easy the solar photovoltaic assembly of explosion behind the bump.
The technical scheme that realizes the utility model purpose is: a kind of solar photovoltaic assembly, comprise battery pack, backboard and cell encapsulant layers, backboard and cell encapsulant layers are laminated on respectively the both sides of battery pack, be provided with the EVA adhesive film between backboard and the battery pack and between cell encapsulant layers and the battery pack, described cell encapsulant layers adopts fibre-reinforced plastics to make.
Further, described backboard is made by the ethylene-tetrafluoroethylene copolymer material.
After having adopted technique scheme, the relative density of fibre-reinforced plastics is between 1.5 ~ 2.0, only has 1/4 ~ 1/5 of carbon steel, hot strength but approaches, even surpasses carbon steel, and specific strength can be compared with high-grade alloy steel, so, the utility model uses the cell encapsulant layers weight made by fibre-reinforced plastics lighter, and intensity can be equivalent to high-grade alloy steel, causes that its impact resistant capability is strong, is not easy explosion behind the bump; The ethylene-tetrafluoroethylene copolymer material is a kind of tough and tensile material, and various mechanical performances reach preferably balance, anti-tear draw extremely strong, tensile strength is high, medium hardness, outstanding impact resistance, flexible life-span are long, high flame retardant.Ethylene-tetrafluoroethylene copolymer also is good dielectric substance, and dielectric strength is high, and dielectric constant is 2.6, and resistivity is high, and dissipation factor is low, only is 0.003.Its low-k, substantially constant in the situation of frequency and variations in temperature.Practicality is wider for the serviceability temperature scope of ethylene-tetrafluoroethylene copolymer, physical attribute impact on most of chemical substances is little, permeability to common gases and aqueous vapor is low, thereby the backboard that uses ethylene-tetrafluoroethylene copolymer to make also has above characteristic, has strengthened the anti-tear ability of drawing of the present utility model, tensile strength, hardness, impact resistance and anti-flammability.
Description of drawings
Fig. 1 is the structural representation of solar photovoltaic assembly of the present utility model.
Embodiment
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model according to specific embodiment also by reference to the accompanying drawings,
As shown in Figure 1, a kind of solar photovoltaic assembly, comprise battery pack 1, backboard 2 and cell encapsulant layers 3, backboard 2 and cell encapsulant layers 3 are laminated on respectively the both sides of battery pack 1, be provided with EVA adhesive film 4 between backboard 2 and the battery pack 1 and between cell encapsulant layers 3 and the battery pack 1, cell encapsulant layers 3 adopts fibre-reinforced plastics to make.
During lamination, laminated layer sequence and conventional assembly have nuance, at first lay the cell encapsulant layers 3 of being made by fibre-reinforced plastics, next lays one deck EVA adhesive film 4, then battery pack 1 back side is upwards laid, again lay EVA adhesive film 4, lay at last the backboard 2 of being made by the ethylene-tetrafluoroethylene copolymer material.
EVA refers to ethylene-vinyl acetate copolymer.
Operation principle of the present utility model is as follows:
The relative density of fibre-reinforced plastics is between 1.5 ~ 2.0, only has 1/4 ~ 1/5 of carbon steel, hot strength but approaches, even above carbon steel, and specific strength can be compared with high-grade alloy steel, so the utility model uses cell encapsulant layers 3 weight of being made by fibre-reinforced plastics lighter, and intensity can be equivalent to high-grade alloy steel, causes that its impact resistant capability is strong, is not easy explosion behind the bump; The ethylene-tetrafluoroethylene copolymer material is a kind of tough and tensile material, and various mechanical performances reach preferably balance, anti-tear draw extremely strong, tensile strength is high, medium hardness, outstanding impact resistance, flexible life-span are long, high flame retardant.Ethylene-tetrafluoroethylene copolymer also is good dielectric substance, and dielectric strength is high, and dielectric constant is 2.6, and resistivity is high, and dissipation factor is low, only is 0.003.Its low-k, substantially constant in the situation of frequency and variations in temperature.Practicality is wider for the serviceability temperature scope of ethylene-tetrafluoroethylene copolymer, physical attribute impact on most of chemical substances is little, permeability to common gases and aqueous vapor is low, thereby the backboard that uses ethylene-tetrafluoroethylene copolymer to make also has above characteristic, has strengthened the anti-tear ability of drawing of the present utility model, tensile strength, hardness, impact resistance and anti-flammability.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
