What is 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. Currently, the solar panel frame thickness of 35 mm is still the top choice for most solar companies.

FAQ on 35mm solar panel frame

The 35mm solar frame is widely recognized as the industry-standard size because it offers an optimal balance between structural rigidity and cost efficiency. It provides robust protection for the solar glass and silicon wafers while avoiding the extra weight and material costs of 40mm profiles, making it highly versatile for various solar applications.

Yes, universal compatibility is a major advantage of the 35mm solar frame. Our profiles are engineered to match standard solar mounting systems, tracks, and mid/end clamps available on the global market. This ensures seamless, hassle-free installation on residential rooftops, commercial carports, and large utility-scale ground arrays.

We manufacture our 35mm solar frames using premium, high-density 6063-T5 or 6063-T6 aluminum alloys. These materials undergo rigorous aging and heat treatments to guarantee excellent tensile strength, hardness, and anti-twisting capabilities, allowing the panels to withstand extreme external vibrations and wind forces.

Our 35mm solar frames feature specialized surface anodizing (exceeding AA 15 microns) that complies with strict architectural building standards. This protective oxide layer delivers exceptional resistance against salt-spray corrosion, chemical ammonia erosion in farming regions, and UV degradation, extending the module’s outdoor lifespan up to 25+ years.
