Ultra Clear Float Solar Glass

Ultra Clear Float Solar GlassThickness:  3.2mm, 4.0mmApplications: Cover glass for PV modules                Cover glass for solar thermal collectors / solar water heaters                Front glass for thin film solar panel                Front glass for photovoltaic glass-glass modules                Substrate for solar mirrors                BIPV modules 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%.MAIN CHARACTERISTICSLight Transmittance3.2mm (1/8"): 91.6%;  4.0mm ( 5/32"): 91.5%Solar Transmittance  3.2mm (1/8"): 91.1%;  4.0mm ( 5/32"):91%Iron Content (Fe₂O₃)≤120ppmSpecific weight (kg/m²)3.2mm (1/8"): 8 ;  4.0mm ( 5/32"): 10Thickness tolerance  ±0.2mmDimension tolerance±1.0mmDiagonal difference  ≤0.1-0.2%Overall Bow/warp  ﹤0.2%Local warp   ≤ 0.3mm / 300mmFragmentation Test  ≥ 40 particles in 25cm²   EN12150-1CertificationEN12150, EN12600, CCC, SGS, SPFMECHANICAL CHARACTERISTICSMechanical strength (N/mm²)    ≥45        Annealed≥120       Tempered, EN12150-1Young modulus (GPa)  73.1        Poisson ratio  0.2    Knoop Hardness (kgf/mm²)  470Density (kg/m³)  2500      THERMAL CHARACTERISTICSHemispherical emissivity (corrected)0.84         Between -18℃and 66℃Expansion coefficient (/℃)  8.6×10﹣6     Between 25℃and 300℃Specific heat0.205        Between 0℃ and 100℃Thermal conductivity (W/m/K) 1         Softening point (℃)   723Annealing point (℃)  544Strain point (℃)  504Solar Transmittance Trend Graph of 3.2mm Low Iron Float Glass
