  • 1. Industry-Leading Power Output
    Our N-type TOPCon module 630W 635W 640W 645W features a 182mm 156-cell design, engineered to deliver exceptional power output for large-scale commercial and utility projects. It sets a new benchmark in energy yield per panel, maximizing generation capacity and supporting high-efficiency solar deployments where performance is critical.

    2. Bifacial Low-Light Performance
    Designed with a full-black front for enhanced light absorption and a transparent rear glass to capture reflected and diffuse light, this module increases energy output by 10–25% even during cloudy weather or low-light periods such as dawn and dusk. It ensures consistent production under challenging irradiation conditions.

    3. Double-Sided Durability
    Built with dual tempered glass on both sides, this bifacial module offers superior resistance to corrosion, potential-induced degradation, and microcracks. It guarantees reliable operation for over 30 years, even in harsh environments including coastal regions and desert climates.

    4. High-Density Cell Arrangement
    The optimized 156cells layout using 182mm wafers significantly improves space efficiency. This design reduces the physical footprint of installations, making it ideal for area-constrained applications such as commercial rooftops and utility-scale solar farms without compromising power output.
