Products > Solar Glass > Ultra Clear float Solar Glass

Ultra Clear float Solar Glass

Thickness:3mm/3.2mm~12mm

Dimension::2100*3600 mm

Applications : Cover glass for PV modules

Cover glass for solar collectors


Description

U/C tempered solar glass is an extra clear float glass .

This ensures the highest energy transmission over the whole solar spectrum

Advantages: with the excellent durability for products of thin film modules,

thermal collectors, and water heater. Excel in supplying big size, special shape

solar 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 .
