Embodiment Construction

[0017] like figure 1 The shown anti-glare photovoltaic module includes a backplane layer 1, and its special feature is that the backplane layer 1 used in the present invention is distributed with a main EVA layer 2. Looking further at that, on the main EVA layer 2 are distributed battery sheets 3 . At the same time, in order to effectively improve the overall optical performance, a secondary EVA layer 4 is distributed on the battery sheet 3 , and a glass layer 5 is provided on the secondary EVA layer 4 . In addition, in order to satisfy the optical performance, reduce the generation of light pollution, and prevent the occurrence of reflective glare, an anti-reflection coating layer 6 is provided on the glass layer 5 . Specifically, the refractive index of the antireflection coating layer 6 is 1.2-1.45, which increases the transmittance of light by 2%, and reduces the reflectivity of light, thereby reducing the intensity of reflected light.

Abstract

The invention relates to an anti-glare photovoltaic module which comprises a rear panel layer. The anti-glare photovoltaic module is characterized in that a main ethylene vinyl acetate (EVA) layer is distributed on the rear panel layer, and a cell is distributed on the main EVA layer. Simultaneously, an auxiliary EVA layer is distributed on the cell, a glass layer is arranged on the EVA layer, and an antireflection film layer is arranged on the glass layer. Accordingly, by means of the antireflection film layer, a coarse layer and an embossing layer, certain light transmittance can be satisfied, light reflectivity can be effectively reduced, reflected light intensities are reduced, and destruction effects of light pollution are avoided, so that the anti-glare photovoltaic module can be applicable to special application occasions such as airports; and the anti-glare photovoltaic module is simple in structure and easy to popularize and manufacture.

Description

technical field [0001] The invention relates to a photovoltaic assembly, in particular to an anti-glare photovoltaic assembly. Background technique [0002] As far as the common photovoltaic modules on the existing market are concerned, the structure and materials used are: tempered glass + EVA + cell + EVA + backplane. Specifically, among the tempered glass, ultra-white embossed tempered glass for photovoltaics is generally used. Therefore, in the actual use of photovoltaic modules, the surface of the module is particularly prone to specular reflection, resulting in reflective glare. This limits the use of modules in important occasions with high light pollution, such as airports. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an anti-glare photovoltaic module in order to solve the above problems existing in the prior art. [0004] The object of the present invention is achieved through the following technical solutions: [0005] A...
