Tempered Solar Glass takes full advantages of the diffuse reflection of the pattern to decrease the light reflection, thus Low Iron Solar Glass has a very high solar transmittance at any angle incidence. Meanwhile, the low iron content of less than 120 ppm enables a very low solar absorbance by the glass itself, and on the contrary increases the transmittance. With the non-toxic chemical composition, low iron patterned solar glass completely conforms to the rigorous environmental requirement of Europe, USA and Japan. It is the ideal encapsulation material for solar panels (PV modules) and the flat solar thermal products.
