Definition of solar panel frame

The solar panel frame is also called a solar panel aluminum frame. It is the most important part in assembling a solar panel. solar panel frame is an extruded aluminum frame that is used to seal and fix solar module components. It can protect the solar cell and glass from damage and breakage.
 
Besides, framed PV panels are better protected during transport than frameless solar panels. So more and more thin film solar companies would love to use the frame on their new solar panel design. Among all these solar panels, the solar panel frame thickness 40mm for 72cell solar module is still the top choice for most solar companies.

Advantage of solar panel frame thickness 40mm

1. Corrosion resistance and strong oxidation resistance; 
2. Strong strength and firmness; 
3. Strong tensile strength; 
4. High elasticity, rigidity, and metal fatigue value; 
5. Convenient transportation and installation; even if the surface is scratched, it will not oxidize and will not affect performance; 
6. It can adapt to various environments through convenient selection of different materials; 
7. The service life is more than 25 years.

FAQ on 40mm solar panel frame

A 40mm solar frame is highly recommended for heavy-duty, large-format PV modules (such as 210mm wafers) and installations in extreme weather regions. If your project is located in areas with severe snow loads, high wind velocities, or utility-scale ground-mounted solar farms that require maximum mechanical stability, the 40mm thickness provides the ultimate structural insurance.

The 40mm solar frame features an augmented cross-sectional profile with thicker aluminum walls and a reinforced interior geometric design. This robust engineering directly enhances the module’s anti-bending and anti-twisting properties, allowing large-area panels to easily withstand front snow loads exceeding 5400 Pa and rear wind loads up to 2400 Pa without glass breakage.

Yes, absolutely. Our heavy-duty 40mm solar frames are strictly manufactured to meet international standards for utility-scale PV projects. The profile dimensions, flange configurations, and pre-drilled mounting hole alignments are fully compatible with mainstream single-axis tracking systems and robust ground-mount racking solutions.

We produce our 40mm solar frames from high-tensile 6000 series aluminum alloys (like 6063-T6) and enforce premium architectural anodizing (AA 15+ microns). Every batch undergoes strict testing for hardness, dimensional tolerances, and coating thickness, ensuring the frame can endure 25+ years of exposure to salt-spray, heavy industrial pollution, and intense UV radiation.
