Product Description
3.2mm, 4mm SPF Certificate PV Glass
Migo Solar Glass is a high performance low iron pattern glass with very high solar energy transmittance. When toughened, its strength and durability make it the ideal choice for crystalline silicon photovoltaic application as well as for solar thermal collectors.
FEATURES:
1. Ultra high solar energy transmittance and low light reflectance.
2. Choice of patterns, either Prismatic/Matt or Matt/Matt to suit the specific application
3. The pyramidal patterns can assist in the laminating process during module manufacture, but can be used on the external surface if desired.
4. both Prismatic/Matt and Matt/Matt surfaces available with Anti-Reflective (AR) coating for optimal solar energy conversion.
5. Available in fully tempered/toughened form to provide excellent strength with resistance to hail, mechanical impact and thermal stress.
6. Easily to be cut, coated and tempered.
