Low Iron Matt/Matt Solar Glass
Low Iron Matt/Matt Solar Glass
Thickness: 3.2mm/4mm
Dimension: 2160*3000 mm
Applications: Cover glass for PV modules
Cover glass for solar collectors
Description
M/M Tempered Solar Glass is Low Iron patterned glass formed with a matt pattern on one face and a matt pattern on the other face.
This ensures the highest energy transmission over the whole solar spectrum
advantages: with the excellent durability for products of photovoltaic modules, thermal collectors, and water heater. Excel in supplying big size, special shapesolar glass (not standard), like triangle, trapezoid, rotundity and other shape,
which have rich experience. Solar Glass conforms to EN12150，meanwhile, we can make Anti-reflection coating on the glass.
