Definition of solar panel frame
Solar panel frame is also called solar panel aluminum frame, It is the most important part in assembling for Solar Panel. solar panel frame is an extruded aluminum frame which used to seal and fix solar module components. It can protect the solar cell and glass out of damage and break.
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.
Advantage of solar panel aluminum frame
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 does not affect performance;
6. It can adapt to various environments through convenient selection of different materials;
7. The service life is more than 30-50 years.
Surface treatment of solar frame
1. Anodized (silver white, black, gold, silver, bronze…) (film coating thickness AA10, AA15, AA18, AA20)
2. Electrophoresis (silver white, black) (film thickness ≥15, ≥16, ≥18, ≥20)
3. Powder spraying, PVDF, etc.
Installation angle
90 degree
45 degree
