Problems solved by technology
The installation cost of installing and fixing photovoltaic modules through brackets is high, and the installation position is relatively fixed; moreover, the surface of conventional photovoltaic modules is encapsulated with glass, so the weight of the photovoltaic module itself will be 12kg / ㎡, which will affect the roof. Carrying capacity has certain requirements

Embodiment Construction
[0020] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.
[0021] like figure 1 As shown, the present invention provides a light-weight flexible photovoltaic module, which includes PVF film layer 1, composite glass fiber layer 2, battery string 3, and FFC double-sided fluorine-containing backsheet 4 from top to bottom. The PVF film layer 1 and the composite glass fiber layer 2, the composite glass fiber layer 2 and the battery string 3, and the battery...

The invention provides a lightweight flexible photovoltaic module. The photovoltaic module comprises a PVF film layer, a composite glass fiber layer, a battery string and an FFC double-sided fluorine-containing backboard which are sequentially distributed from top to bottom; the PVF film layer and the composite glass fiber layer are connected with each other through an EVA film; the composite glass fiber layer and the battery string are connected with each other through an EVA film; and the battery string and the FFC double-sided fluorine-containing backboard are connected with each other through an EVA film; one side of the PVF film layer, which is far away from the composite glass fiber layer, is sprayed with a coating liquid; and one side of the PVF film layer, which is closed to the composite glass fiber layer, is provided with a PET film, a water blocking film and a fluorine-containing coating which are distributed sequentially from top to bottom and are connected with one anotherthrough an adhesive. The weight of the photovoltaic module is reduced to 3.5 kg / m<2>, so that the roof bearing requirement of the photovoltaic module is far lower than that of a conventional module;the photovoltaic module is flexible and can be installed on a curved roof; no installation supports are needed for installing the photovoltaic module; it just needs to install adhesive strips on an installation surface so that the photovoltaic module can be installed; and the installation position of the photovoltaic module is not limited.
Description
technical field [0001] The invention relates to the technical field of photovoltaic components, in particular to a lightweight and flexible photovoltaic component. Background technique [0002] At present, most of the solar cell modules on the market are fixed and installed by brackets, and can only be installed in flat areas. Installing and fixing photovoltaic modules through brackets has high installation costs and relatively fixed installation locations; moreover, the surface of conventional photovoltaic modules is encapsulated with glass, so the weight of the photovoltaic module itself will be 12kg / ㎡, which will affect the roof. Carrying capacity has certain requirements. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a lightweight flexible photovoltaic module, the technical solution of which is: [0004] The photovoltaic module includes a PVF film layer, a composite glass fiber lay...
