Painted Aluminum For Solar Panel

0 Comment

Painted aluminum for solar panel refers to the aluminum alloy material used to make solar panels, which has the characteristics of high conductivity, high strength, corrosion resistance and high temperature resistance. In solar cells,  painted aluminum sheet is used as the main substrate material, and it is usually required to have high flatness, smooth surface, and no cracks, oxidation, and other defects to ensure the performance and lifespan of solar cells. Painted aluminum sheet for solar backsheet is widely used in photovoltaic power generation, power equipment, electrical appliances, transportation, and aerospace.

The backsheet of a solar panel is located on the backside of the solar panel, providing protection and support for the solar cells, and it has reliable insulation, water resistance, and aging resistance. The coating on the solar panel may also contain metals such as color coated aluminum sheet to improve the reflection efficiency of the panel. Fluorocarbon painted aluminum for solar panel has good weather resistance and corrosion resistance, which can effectively prevent the corrosion of harmful substances such as acids, alkalis, and chlorides in the air and moisture on the solar panel. Due to the high electronegativity of fluorine and the strong bond energy between carbon and fluorine, as well as the tight, rigid, and smooth molecular arrangement in fluorine-containing materials, fluorine-containing films have excellent chemical corrosion resistance, heat resistance, oxidation resistance, and weather resistance.


With technological development, painted aluminum for solar panel from Haomei Aluminum now have not only high performance in terms of temperature resistance and weather resistance but also better flame retardancy and compactness, making them suitable for various climate conditions and providing safety assurance for the photovoltaic industry.
