[0031] As attached Figure 6-7 As shown, a plurality of sunshade units are arranged in sequence along the vertical direction, and each sunshade unit includes a photovoltaic sunshade panel 3 and a non-photovoltaic sunshade panel 4; the photovoltaic sunshade panel 3 is fixedly connected to the non-photovoltaic sunshade panel 4 and is arranged horizontally.

[0032] Specifically, the photovoltaic sunshade panel 3 includes a first stainless steel auxiliary frame 31 and a plurality of photovoltaic glasses 32. The plurality of photovoltaic glasses 32 are all installed and fixed on the first stainless steel auxiliary frame 31, and form a whole with the first stainless steel auxiliary frame 31, so as to facilitate overall processing, transportation and installation in the factory. In this embodiment, the number of photovoltaic glasses 32 is three, and the three photovoltaic glasses 32 are interconnected to form a complete plane. In actual application, the number of photovoltaic glasses 32 can also be changed according to actual conditions. Among them, the photovoltaic glass 32 is formed by bonding two pieces of 6 mm thick ultra-white tempered glass 42, two pieces of 1.3 mm thick POE film and photovoltaic cells.

[0033] The light transmittance of each photovoltaic glass 32 is different, so the number and arrangement of photovoltaic panels with high and low light transmittances can be adjusted according to actual shading needs, thereby achieving the effect of similar shading panels having different shading properties.

[0034] The non-photovoltaic sunshade panel 4 includes a second stainless steel auxiliary frame 41 and multiple tempered glasses 42.

In actual application, the number can also be changed according to actual conditions, and the cross-sectional size of the non-photovoltaic sunshade panel 4 is consistent with that of the photovoltaic sunshade panel 3.

[0035] As attached Figure 4-5 As shown, multiple cable assemblies are arranged in the vertical direction and are respectively fixed on the outside of the photovoltaic shading panel 3, the outside of the non-photovoltaic shading panel 4 and the connection between the photovoltaic shading panel 3 and the non-photovoltaic shading panel 4; specifically, each cable assembly includes a group of stainless steel cables 5 and multiple stainless steel castings 6, and the multiple stainless steel castings 6 are respectively fixed on the ends of the photovoltaic shading panel 3 and the non-photovoltaic shading panel 4, and the connection between the photovoltaic shading panel 3 and the non-photovoltaic shading panel 4 shares a common stainless steel casting 6.
