Understanding the Problem: Why Bubbles Form in Double-Glass Panels

Bubbles in double-glass components, often seen in solar modules, occur due to trapped air or gases during manufacturing. These imperfections can reduce light transmission, lower energy output, and even cause delamination over time. For example, a 2023 industry study found that 1.2% efficiency loss occurs for every 5% increase in bubble coverage area.

Common Causes of Bubbles

• Improper lamination temperatures (ideal range: 140°C–160°C)
• Uneven pressure during glass sealing
• Contaminated sealing materials
• Rapid cooling processes

Step-by-Step Solutions for Existing Bubbles

If you''ve spotted bubbles in your double-glass units, here''s what to do:

1. Assess the Severity: Use UV fluorescence testing to identify hidden bubbles.
2. Localized Heating: Apply controlled heat (120°C–130°C) to redistribute the encapsulant.
3. Pressure Reapplication: Use vacuum bags to eliminate air pockets.
4. Material Replacement: For persistent cases, replace the affected encapsulant layer.

Case Study: EK SOLAR''s Bubble-Reduction Success

In 2022, EK SOLAR implemented automated pressure calibration in their production line, reducing bubble-related defects by 78% within six months. Their quality control checklist now includes:

Parameter	Before	After
Bubble Incidence Rate	5.3%	1.2%
Energy Yield Loss	2.8%	0.6%

Prevention: Better Than Cure

To avoid bubbles altogether:

• Maintain laminator temperature within ±2°C of setpoints
• Use low-viscosity encapsulants like POE (Polyolefin Elastomer)
• Implement real-time vacuum monitoring

FAQs: Bubbles in Double-Glass Components

• Q: Can small bubbles be ignored?A: Bubbles under 1mm usually don''t affect performance but monitor for growth.
• Q: How often should inspections occur?A: Bi-annual checks for residential systems; quarterly for utility-scale installations.
