Why the Double-Glass PV Lamination Process Matters

In today's solar industry, the double-glass photovoltaic module lamination process has become a game-changer. Imagine sandwiching solar cells between two layers of tempered glass—like a high-tech energy-generating panini. This method boosts durability while maintaining efficiency, making it a hot topic for manufacturers and project developers alike.

Target Audience & Content Strategy

This article targets:

• Solar panel manufacturers exploring advanced production techniques
• Project developers seeking durable PV solutions
• Engineers optimizing module lifespan in harsh environments

Key Steps in the Lamination Process

Let's break down this glass-glass module production workflow:

• Layer Assembly: Positioning solar cells between two 2mm tempered glass sheets
• Encapsulation: Using ethylene-vinyl acetate (EVA) or POE films at 150°C
• Vacuum Sealing: Removing air pockets under 95% vacuum conditions
• Curing: 15-minute thermal treatment for polymer cross-linking

Performance Comparison: Single vs Double Glass

Latest Industry Trends (2024 Update)

The market for bifacial double-glass modules grew 37% YoY, driven by:

• Ultra-thin glass technology (1.6mm variants now available)
• POE/ionomer hybrid encapsulant adoption
• Automated optical inspection systems

Real-World Application: Desert Solar Farm Case

A 50MW plant in Nevada reported:

• 0.21% annual degradation vs 0.45% in standard modules
• 92% survival rate in sandstorm conditions
• 3.8% higher ROI over 25-year lifecycle

Optimizing Your Lamination Process

Three critical control parameters:

1. Temperature uniformity (±2°C across laminator plates)
2. Vacuum ramp rate (≤5 mbar/sec)
3. Edge sealing consistency (＜0.5mm variation)

Common Pitfalls to Avoid

• Over-curing EVA layers causing yellowing
• Insufficient edge delamination force (＞50N/cm required)
• Glass surface contamination pre-lamination
