AR Coated Tempered Glass For Solar Panel Backsheet
1. What is Solar Tempered Glass?
Solar tempered glass is a type of safety glass that has been heat-treated (tempered) to enhance its strength and thermal resistance. It is commonly used in solar panels, solar thermal systems, and building-integrated photovoltaics (BIPV) due to its durability and ability to withstand high temperatures and mechanical stress.
2. Key Features
High Strength: 4–5 times stronger than regular annealed glass.
Thermal Resistance: Can endure extreme temperature fluctuations (e.g., from -40°C to 300°C).
Safety: Breaks into small, blunt pieces (not sharp shards) when shattered, reducing injury risks.
UV Resistance: Protects solar cells from degradation while allowing optimal sunlight transmission.
Optical Clarity: High light transmittance (typically >90%) for efficient energy absorption.
3. Applications
Solar Panels (PV Modules): Protects photovoltaic cells from weather and impacts.
Solar Water Heaters: Used as a cover to trap heat while resisting thermal stress.
Greenhouses & Skylights: Combines durability with sunlight transmission.
Building Facades (BIPV): Integrates solar energy generation into architectural glass.
4. Benefits Over Regular Glass
✔ Durability: Resists hail, wind loads, and thermal shock.
✔ Safety: Meets international safety standards (e.g., ANSI Z97.1, EN 12150).
✔ Longevity: Extends the lifespan of solar installations.
✔ Customizability: Available in varying thicknesses (3mm–10mm+) and coatings (anti-reflective, textured).
5. Limitations
Cannot be cut/drilled after tempering (must be shaped beforehand).
Higher cost than annealed glass but justified by performance.
6. Industry Standards
Tempering Process: Heated to ~620°C then rapidly cooled for compressive strength.
Certifications: UL 1703 (solar panels), IEC 61215 (PV module safety).
