The Critical Role of Lamination Frames in Photovoltaic Double-Glass Modules

In solar energy systems, the lamination frame of photovoltaic double-glass modules isn't just a structural component—it's the unsung hero ensuring durability, efficiency, and longevity. This article dives into why lamination frames matter, how they impact solar panel performance, and what innovations are shaping their future.

Why Lamination Frames Are Essential for Double-Glass PV Modules

Photovoltaic double-glass modules have gained popularity due to their enhanced durability and resistance to environmental stress. However, their success hinges on one often-overlooked element: the lamination frame. Here's why:

• Structural Integrity: Lamination frames hold glass layers and solar cells together during the encapsulation process.
• Moisture Resistance: They prevent water ingress, a common cause of module degradation.
• Thermal Management: By maintaining even pressure during lamination, they reduce hotspots that can lower efficiency.

Material Choices: Balancing Cost and Performance

Most manufacturers use aluminum alloys for lamination frames due to their lightweight and corrosion-resistant properties. However, alternatives like composite polymers are emerging. For example, EK SOLAR recently tested a carbon-fiber-reinforced frame that reduced weight by 22% while maintaining rigidity—a game-changer for rooftop installations.

Material	Weight (kg/m)	Cost ($/m)	Lifespan (Years)
Aluminum 6063	1.2	4.50	25+
Carbon Fiber	0.9	12.00	30+
Recycled Polymer	1.1	3.80	15-20

Challenges in Lamination Frame Design

Designing a reliable lamination frame isn't just about picking the right material. Consider these hurdles:

• Thermal Expansion: Temperature fluctuations can warp frames, leading to delamination. Modern designs incorporate expansion joints.
• Manufacturing Precision: Even a 1mm misalignment during lamination can reduce module efficiency by up to 5%.
