The process of manufacturing solar glass involves melting raw materials, forming sheets of glass, and applying an anti-reflective coating. The quality of the glass used can greatly affect the performance and longevity of the solar panel. Solar glass has emerged as the leading cost contribution to solar modules globally today, with eight suppliers headquartered in China accounting for more than 90% market share. Over the past few decades – from when solar PV moved into mass production status – the polysilicon sector was often the. With PV module capacity ramping up, glass suppliers have been investing in new solar glass production capacity. As in India and China, new facilities are popping up in North America, with unique twists to ensure competitiveness, such as using recycled material. These materials undergo significant heating to produce the molten glass.
