3.2mm/4mm Tempered Solar Glass for Solar Panels
Thickness: 3.2/4mm
Glass Features
-- Ultra Clear Float Solar Glass is a kind of extra clear low iron float glass with light transmission higher than 91.5%. Its high performance stability and good process ability make it one of the best choices for photovoltaic modules, solar thermal collectors and solar mirrors.
--Ultra Clear Float Solar Glass offers superior solar energy transmittance and is stable under solar radiation. It also survives harsh environmental conditions and protects the sensitive components of solar modules from water and humidity ingress.
-- Ultra Clear Float Solar Glass is fully tempered as per EN12150. Meanwhile, anti-reflective coating can be deposited on one or two glass surfaces to increase light transmittance by 2%.
Classify&Application
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.
Low Iron Mirror is that Low Iron Float Glass coated silver layer, according the collecting ways, there is Flat Low Iron Mirror and Bending Low Iron Mirror.
