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.
