Abstract

The invention relates to the technical field of a solar cell component, in particular to a light easy-to-install component. A fluorine-containing resin film, thermoplastic resin, a reinforcing plate, thermoplastic resin, a connected cell, thermoplastic resin and a backing plate are sequentially stacked to form the whole component; the periphery of the component is packaged through a packaging tape; the packaging material is externally protected by soft plastic materials; and a plurality of convex reinforcing ribs are arranged on the backing plate. The top surface of each reinforcing rib is adhered to the backing plate through a double-sided sticky tape. The component is directly adhered to the mounting plane through the double-sided sticky tape at the bottom of each reinforcing rib. The component is light in weight, ensures that drilling and screw installation can be reduced as much as possible, and is quick and reliable in installation on the premise of requiring construction such as drilling installation carriers.

Description

Light-duty easy installation component

Technical field

The present invention relates to the solar module technical field, particularly a kind of light-duty easy installation component.

Background technology

Existing photovoltaic cell component, be essentially toughened glass, the plastic material backboard, the laminating technology of EVA and cell piece, and the fixed form that adopts the sealing of aluminium frame around the laminate, this structure comprises technique, reliability testing, install and wait all comparative maturities, but it also there are many deficiencies, for example:

1, assembly is installed and usually need to keel be set in addition, causes installation cost higher, and the price along with assembly itself constantly reduces simultaneously, and installation cost causes actual every watt of assembly to hold at high price in the modular assembly continuous rising of ratio regular meeting originally;

2, simultaneously, because assembly weight is larger, in carrying, in the process of installation, cost is higher, and simultaneously for eminence, such as application such as roofs, the weight of assembly also has larger impact for installation cost; Simultaneously, in the situation that breaking out of fire when assembly falls, easily causes personnel's injures and deaths;

3, the logistics transportation expense of assembly also is the important composition of assembly cost, and the component count that can place of the previous container of order the inside is on the low side, and it also is more considerable causing average every watt cost of transportation.

Summary of the invention

Technical problem to be solved by this invention is: design a kind of light-weighted assembly that punching and screw are installed that as far as possible reduces, do not needing to change building simultaneously, curtain walls etc. are installed carrier structure, perhaps do not need to hole and wait under the prerequisite of constructing carrier is installed, and can finish reliably rapidly installation.

The technical solution adopted for the present invention to solve the technical problems is: a kind of light-duty easy installation component; the cell piece, the backboard that comprise fluoroplastic film, stiffener, connection; stacking gradually according to the order of the cell piece of fluoroplastic film, thermoplastic resin, stiffener, thermoplastic resin, connection, thermoplastic resin, backboard is that assembly is whole; encapsulate by packaging belt around the assembly; at the outside soft plastic material protection that adopts of encapsulating material, the reinforcement of many protrusions is set at backboard.

All has two-sided tape on the end face of reinforcement and the bottom surface, the end face of reinforcement is pasted on backboard by two-sided tape, assembly is directly pasted on mounting plane by the two-sided tape of the bottom surface of reinforcement, and many reinforcements form vent passages between assembly backboard and mounting plane.

The invention has the beneficial effects as follows: 1. this assembly is a kind ofly can reduce punching as far as possible, the modular construction that screw is installed; 2. this assembly is a kind of light-weighted assembly, and the weight of decrease assembly makes the transportation of assembly, and installation can more convenient workman operate, and reduces cost of labor; 3. this assembly is a kind of slim assembly, increases substantially the saturation of container assemblies, reduces the transportation logistics cost of assembly; 4. in decremental component weight, in the situation of thickness, by every optimal design, can make the efficient of assembly, the energy ability of environmental performance and anti-load can continue to satisfy the requirement of all standard; 5. utilize different mounting meanss, do not needing to change building, curtain wall etc. are installed carrier structure, perhaps need to hole and wait under the prerequisite of constructing carrier is installed, and can finish reliably rapidly installation.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples;

Fig. 1 is structural representation of the present invention;

Among the figure, 1. fluoroplastic film, 2. stiffener, 3. cell piece, 4. backboard, 5. thermoplastic resin, 6 two-sided tapes, 7. reinforcement, 8. mounting plane.

Embodiment

As shown in Figure 1, a kind of light-duty easy installation component, the cell piece 3, the backboard 4 that comprise fluoroplastic film 1, stiffener 2, connection, stacking gradually according to the order of fluoroplastic film 1, thermoplastic resin 5, stiffener 2, thermoplastic resin 5, the cell piece 3 that connects, thermoplastic resin 5, backboard 4 is that assembly is whole

Cancel the design of original aluminium frame edge sealing, encapsulate by packaging belt around the assembly, at the outside PVC that adopts of encapsulating material, the soft plastic material protections such as EPDM, thus greatly reduce the thickness of assembly, reach the purpose that reduces the logistics transportation cost.The reinforcement 7 of many protrusions is set at backboard, comes the anti-load-carrying ability of stiffener assembly by the pattern of this many reinforcements.

All has two-sided tape 6 on the end face of reinforcement 7 and the bottom surface, the end face of reinforcement 7 is pasted on backboard by two-sided tape 6, assembly is by the two-sided tape 6 of the bottom surface of reinforcement 7, directly paste on mounting plane 8, many reinforcements 7 form vent passages between assembly backboard and mounting plane 8.

Take at the roof installation component as example, use two-sided tape 6, with assembly by reinforcement 7, directly stick on the roof surface is installed, reach and utilize roof and reinforcement 7 to come bearing load, there is certain distance on assembly backboard and roof, enough ventilations can be provided, keep assembly temperature

The film that is made into for fluorine resin of fluoroplastic film 1 wherein, such as ETFE etc., thickness 100-300um has the high transmission rate more than 90%, and good anti-aging, uvioresistant, waterproof, the performances such as insulation, Main Function is to prevent ultraviolet ray, and the encapsulating structure of protection assembly is necessary;

Wherein thermoplastic resin 5 is the thermoplasticity resins such as EVA, and this thermoplastic resin contains the UV absorbent, can be good at protecting the photovoltaic element of below;

Wherein stiffener 2 is the reinforcement structure of assembly, and density is 0.9～2.0g/cm ³Between, thickness range 2-5mm, energy is the weight of lightening material significantly, and light transmittance has the toughness of height at high light transmissive material more than 90%, and deformation temperature is at the exotic material more than 120 °, and material mainly can be selected the high light transmittance plastics such as PC;

Wherein cell piece 3 is cell piece, can be monocrystalline, polycrystalline or other forms of solar battery sheet;

Its dorsulum 4 is the insulating back panel material.
