Embodiment 1

[0044] image 3 It is a flow chart of the production process of solar photovoltaic materials according to an embodiment of the present invention, such as image 3 As shown, cell sorting: firstly, cells with chipped corners, hidden cracks, poor grid line printing, splinters, color difference, etc. are screened out through primary selection, and then cells with low power are screened out by testing equipment. Come out and classify the cells by power to ensure the quality and power optimization of the components.

[0045] Single-chip welding: connect the soldering strip to the busbar on the front side (negative pole) of the battery, and lead out the negative pole of the battery sheet. The soldering strip is a tin-coated copper strip.

[0046] Soldering string: use the ribbon combined with auxiliary materials such as solder wire, flux, etc. to correctly connect the individual cells that have been soldered in series.

[0047]Lamination: Put the toughened glass with a thickness of...

Embodiment 2

[0055] Figure 4 , 5 , 6 represents another embodiment of the present invention, such as Figure 4 , 5 , shown in 6: the components of a light-duty solar photovoltaic power generation system produced by the method of the present invention adopt tempered glass with a thickness of 0.8mm, its iron content is not more than 0.2%, the toughening performance is good, and the weight is only 2 kg per square , and can meet the mechanical strength against 2400pa wind intensity, at the same time, in the wavelength range of solar cell spectral response of 320-1100nm, the light transmittance reaches more than 92%;

[0056] EVA is a hot-melt adhesive that contains a cross-linking agent. After hot pressing, it will undergo fusion bonding and cross-linking solidification. The cured EVA has elasticity, envelops the battery layer up and down, and can be bonded with the tempered glass layer. Improve glass light transmittance;

[0057] The material of the backplane layer in this embodiment is ...

Abstract

Disclosed are a light solar photovoltaic power generation component and a stacking method in the production technology of the component. A component body sequentially comprises tempered glass layers, a thermoplastic resin layer (EVA), a solar cell string group piece, a thermoplastic resin layer (EVA) and a back plate layer from bottom to top, preferably, reinforcing ribs are bonded on the back face of the component body, screw holes are formed in the component body, and the photovoltaic component is in threaded connection with a bearing carrier. The stacking method in the production technology comprises the steps that the upper face and the lower face of the component body are respectively and additionally provided with the tempered glass layer with the thickness of 4 mm, the two short edges of the component body are respectively and manually held, the component body rotates by 180 degrees and is exchanged up and down, the two tempered glass layers with the thickness of 4 mm are removed, and the next working procedure is executed. According to the method, the problems that in the production process, the component in the stacking step is not easy to move, and the tempered glass is easily smashed are solved, and therefore the light solar photovoltaic power generation component which has the qualified quality and is light and high in power generation efficiency is obtained.

Description

technical field [0001] The invention relates to a photovoltaic power generation component and a production process thereof, in particular to a light-weight solar photovoltaic power generation component and a stacking method in the production process thereof. Background technique [0002] Nowadays, there are more and more examples of using solar photovoltaic modules to generate electricity. While people enjoy this clean energy, they have higher and higher requirements for the applicability of solar photovoltaic modules. At present, solar photovoltaic modules are widely used in factory roofs and parking sheds. , villa roof and ground photovoltaic power station. The weight of ordinary solar panels is generally 20-30KG, and a support bracket is required for installation. For new buildings, the support bracket is usually erected after the roof cover is installed and before the roof waterproofing material is installed, and the installation steps are cumbersome; Buildings, because...
