Aluminum extrusions are widely used in photovoltaic systems to support and mount solar panels,
 mounting systems and other key components. Here is some common information about aluminum extrusions
 used in photovoltaics:

1、Material: Photovoltaic aluminum profiles are usually made of high-strength, corrosion-resistant 
aluminum alloy materials,
 such as 6000 series aluminum alloys (such as 6063, 6061, etc.). These alloys have good strength, 
lightweight and oxidation resistance properties and are suitable for outdoor applications.

2、Structural design: Photovoltaic aluminum profiles usually adopt a unique structural design to
 meet the installation requirements of solar panels. Common profile shapes include H-shape,
 T-shape, U-shape, etc., which have good rigidity and stability, and can support and fix solar panels.

3、Mounting bracket: Aluminum profiles play a key role in the photovoltaic mounting bracket system. 
The mounting bracket needs to have good strength, stability and durability to withstand the weight 
of the solar panel and the influence of the external environment. Aluminum profiles can meet these
 requirements and have the advantages of light weight, easy processing and corrosion resistance.

4、Accessories and connectors: Photovoltaic aluminum profiles usually use special accessories 
and connectors, such as corner codes, bolts, nuts, etc., to facilitate assembly and installation. 
These accessories and connectors can make the aluminum profile more stable and reliable during 
installation.

5、Weather resistance: Since photovoltaic systems are usually installed in outdoor environments, 
aluminum profiles need to have good weather resistance and be able to resist the erosion of the sun, 
wind and rain, and other natural environments. The corrosion resistance of aluminum alloys makes 
them ideal for photovoltaic systems
