Why PV Laminated Glass Quality Matters

Photovoltaic laminated glass serves as the protective shield for solar panels, withstanding weather extremes while maintaining light transmittance. A single 0.5mm air bubble or delamination can reduce energy output by 8-15% according to NREL studies.

The 4-Step Inspection Process

1. Visual Examination

Technicians use LED backlighting to identify:

• Surface scratches
• Inclusions (dust particles)
• Color inconsistencies

2. Mechanical Testing

Popular methods include:

Test Type	Standard	Acceptance Criteria
Impact Resistance	IEC 61215	Withstands 1kg steel ball drop from 1m
Thermal Cycling	UL 1703	No bubbles after -40°C to +85°C cycles
