GLASS DESCRIPTION
●MIGO 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 processability make it one of the best choices for photovoltaic modules, solar thermal collectors and solar mirrors.
●MIGO 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.
●MIGO Ultra Clear Float Solar Glass is fully tempered as per EN12150. Meanwhile, anti-reflective coating can be deposited on one side of glass to increase light transmittance by 2%.
