Photovoltaic cell is a kind of material used in the transition from solar radiation to electricity. It is mainly made of silicon and it goes through a physical phenomenon called photovoltaic effect. When the photovoltaic cell is subjected to solar radiation, the energy of the photons is powerful enough to split into electrons, which then start to move, and that it is this displacement of electrons that carries the electric current. However, the voltage of the generated current is not high, so the cells will be mounted in series in order to obtain photovoltaic modules or panels through higher voltage.
The solar profile is used to protect the solar panel.
Solar photovoltaic frame is applied to protect the glass edge, strengthen the sealing performance of photovoltaic modules and improve the overall mechanical strength of photovoltaic modules. It is required by good oxidation resistance and corrosion resistance. And the main materials of the frames include stainless steel, aluminum alloy, rubber and reinforced plastics, etc. Among these material, the overall performance of aluminum alloy is the most in line with the requirements of photovoltaic module border. At present, aluminum alloy frame is the most widely used, accounting for over 95%.
Why chose aluminum frame?
High strength, stable, reliable and corrosion resistance.
In fact, there are many kinds of surface treatments that can be used on aluminum frames, such as spray paint, PVDF and electrophoresis. And most of the solar panel frames are anodized. The most commonly used colors for solar extruded profiles are black and silver.
