SUN-T by AGC Solar is extra clear float glass optimized for thermal collectors.

PV200

High strain point glass substrate for photovoltaic solar cell.

Type

High strain point glass

 

Applications

Back glass for thin film
photovoltaic module (CIGS) 

Much less deformation in the heating process than soda-lime glass.

Small variations in thermal shrinkage after the heating process. Suits processes for large-size substrates.
