Solar glass is a kind of high performance low iron glass, also be called photovoltaic glass and engergy saving glass, which mainly used on solar panel with high solar energy transmittance. When be toughened, its strength and durability make it become the ideal choice for crystalline silion photovoltaic application and solar thermal collectors. 

Low Iron Patterned Glass is often used as the cover of PV Module, small protuberant spots can enhance the solar transmittance
Low Iron Float Glass is often used to be the thin film solar cell sustrate, we have the very flat Tempered Low Iron Float Glass
you want.
Anti-Reflection Glass is often used to be cover of PV Module, through anti-reflection the glass is similar function with Low Iron
Patterned Glass.
