2.5 mm Ultra-Clear Patterned Double-Coated Fully Tempered Glass
| Parameter | Technical Specifications | Notes |
| Glass Material | Ultra-Clear Low-Iron Patterned Soda-Lime Silicate Glass | Low iron content minimizes light absorption |
| Standard Thickness | 1.6mm、2.0mm 2.5mm、3.2mm | Typical thicknesses are 1.6 mm, 2.0 mm, and 2.5 mm for dual-glass PV modules, and 3.2 mm for single-glass PV modules |
| Standard Dimensions | Compatible with 1756 / 2272 / 2376 / 2459 module formats (custom sizes available) | Compatible with all mainstream PV module formats |
| Glass Pattern | Single-Sided Patterned Glass (Diamond / Fine Pattern) | The matte side is laminated with the encapsulant, while the glossy side serves as the light-incident surface |
| Coating Process | Single-Sided, Double-Layer Anti-Reflective (AR) Coating | Uniform coating with excellent adhesion and outstanding aging resistance |
| Iron Content | ≤0.012% | Ultra-low iron content ensures high light transmittance |
| Surface Roughness (Textured Side) | 0.3-1.2μm | Optimized for EVA/POE encapsulant lamination, enhancing bond strength |
