What is the difference between solar photovoltaic glass and float glass?

Photovoltaic glass is a special type of glass that converts natural light into electrical energy by encapsulating solar cell modules in glass layers. Usually, low iron tempered glass or double-layer glass is used, and anti reflective coating and transparent conductive layer are coated on the surface.
Float glass is a common glass manufacturing process, in which glass raw materials (such as silica sand, sodium carbonate, limestone, etc.) are melted and uniformly flowed out from above the glass melt bath, cooled and solidified into thin glass sheets. This technology can produce high-quality, uniformly thick glass with a wide range of applications.
The difference between photovoltaic glass and float glass is mainly reflected in the following aspects:
Different uses: Photovoltaic glass is mainly used in the manufacturing of solar panels, while float glass is widely used in fields such as construction and automobiles;
Different materials: Photovoltaic glass usually uses special materials such as low iron tempered glass or double-layer glass, while float glass is produced using ordinary glass raw materials through special processes;
The manufacturing methods are different: photovoltaic glass needs to be coated with anti reflective coatings and transparent conductive layers on the surface, and the solar cell modules need to be encapsulated inside. Float glass, on the other hand, is made by melting raw materials into thin glass sheets.
Different performance requirements: Photovoltaic glass needs to have certain special properties such as transmittance, reflectivity, and wind pressure resistance, while float glass mainly requires uniform thickness, high strength, and transparency.
