Extruded aluminum profile for the solar panel frame system
Extruded aluminum profiles are usually used for solar panel frames and solar mounting system, because aluminum extrusions have high strength, light weight and strong corrosion resistance. The aluminum frame seals and secures the solar cell module between the glass cover and back plate, ensuring structural stability and extending battery lifespan. Aluminum alloy, with its moderate price, strength, processability, corrosion and weather resistance, and recyclability, is an ideal material for solar panel support in solar mounting system, requiring no maintenance over the 25-year operation period.Quick Quote

- Anodized aluminum alloy with transparent coating, high corrosion resistance and oxidation resistance.
- High tensile strength performance, improving snow load resistance, rain resistance, wind impact resistance and so on.
- The excellent mold reduces the machining allowance to 0.02mm while ensuring the accuracy to ensure smooth installation.
- The aluminum alloy photovoltaic support is generally in the form of long rod, and the stress is tensile stress and compressive stress, which is easy to buckle and deform, so the design wall thickness is generally not less than 1.5 mm.
- The commonly used aluminum alloy series for solar photovoltaic brackets need to undergo aging heat treatment to achieve the required strength.
- China Aluminum strictly controls the solution treatment and aging heat treatment process to ensure the required strength of the aluminum alloy brackets.
- The oxide film thickness is generally AA15, but in humid or heavily polluted areas, AA20 or AA25 can be chosen to improve corrosion resistance.
Aluminum sheet, strip, flat bar for solar panel
The cooling speed of aluminum is fast compared to the traditional materials, which has a significant advantage in solar PV system because the increase of PV cell temperature will reduce the power generation efficiency. And with is good conductivity, aluminum has gradually replaced the position of silver, copper and stainless steel in the solar panels.
