Double Glass PV Module

1. Product Overview

Our double glass PV module represents the pinnacle of solar photovoltaic technology, engineered for superior durability and performance in demanding environments. Featuring a robust bifacial design with two layers of tempered glass encapsulating high-efficiency PERC or TOPCon solar cells, this double glass PV module delivers exceptional energy yield while offering unmatched resistance to environmental stressors such as hail, wind, snow, and ammonia corrosion.

Ideal for utility-scale projects, commercial rooftops, and residential installations, the double glass PV module achieves power outputs ranging from 500W to 700W per panel, with module efficiencies exceeding 22%. The frameless construction enhances aesthetics and reduces micro-cracks, ensuring long-term reliability over a 30-year lifespan. By utilizing advanced encapsulants and edge sealing, our double glass PV module minimizes PID (Potential Induced Degradation) and LID (Light Induced Degradation), maximizing return on investment for international buyers seeking premium solar solutions.

This product line is certified to international standards including IEC 61215, IEC 61730, UL 61730, and CE, making it a trusted choice for global B2B markets. Whether you're outfitting floating solar farms or agrivoltaic systems, the double glass PV module provides a future-proof platform for sustainable energy generation.
