Aluminium Profiles Supplier : Why is Aluminum Profiles Used

Predominantly composed of monocrystalline or polycrystalline silicon solar cells and tempered glass, solar photovoltaic panels are brittle and easily breakable, so frames are necessary for protection. If frameless panels are used, the risk of electric leakage increases. Thus, aluminum frames are the dominant products on the market.

Solar Glass & Mirrors, Photovoltaics | Solar Energy

Glass is used in photovoltaic modules as layer of protection against the elements. In thin-film technology, glass also serves as the substrate upon which the photovoltaic material and other chemicals (such as TCO) are deposited. Glass is also the basis for mirrors used to concentrate sunlight, although new technologies avoiding glass are emerging..
