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.
