Technical FAQ: Trina 425-450W Dual Glass Module

1. What encapsulation material is used between glass layers?

The module uses high-transmittance POE (Polyolefin Elastomer) encapsulant instead of standard EVA. POE offers superior resistance to humidity, better adhesion to glass surfaces, and significantly lower degradation rates under UV exposure, contributing to the extended 25-year performance warranty.

2. What electrical safety certifications does this module hold?

The panel meets IEC 61730 Class A safety standards with fire rating certification. Additional certifications include IEC 61215 for performance standards, IEC 61701 salt mist corrosion certification (Level 6), and IEC 60068-2-68 dust test compliance for desert applications.

3. How does the bifaciality factor impact energy production?

With a bifaciality factor of 70±5%, these modules can generate 8-25% additional energy from rear-side illumination depending on ground albedo. A white surface can yield approximately 22% energy gain compared to monofacial equivalents, making them ideal for installations with reflective surfaces.

4. What is the significance of the -0.35%/°C temperature coefficient?

This temperature coefficient indicates maximum power loss of just 0.35% per degree Celsius above 25°C ambient temperature. At 65°C operating temperature, this translates to only 14% power reduction compared to industry averages of 18-20%, significantly boosting summer energy yield.

5. What mounting systems are compatible with dual-glass modules?

Specialized clamps supporting 4-point or 6-point mounting are required. The panel is compatible with most standard racking systems including Schletter, K2, and Unirac, using corrosion-resistant stainless steel clamps with torque specifications of 15-20Nm to prevent glass stress fractures.

6. How does the half-cut cell design enhance reliability?

Halving the cells reduces current flow through each circuit by 50%, diminishing resistive losses and operating temperatures. This design limits shadow impact - partial shading affects only half the module, maintaining at least 50% output. Additionally, the lower operating temperature decreases thermal degradation by approximately 0.05%/year compared to full-cell modules.

7. What testing validates the 25-year performance warranty?

Extended sequential testing based on IEC TS 63209 includes 400 thermal cycles (IEC 61215 requires 200), 3000Pa mechanical load testing (exceeding 2400Pa standard), and 3000-hour damp heat testing. Accelerated testing correlates to real-world 40-year deployment data, ensuring linear degradation not exceeding 0.55%/year.
