Eastman 590W N-Type TOPCon Bifacial Solar Panel (G2G1770-HAD, 144 Half-Cut Cells)
The Eastman 590W N-Type TOPCon Bifacial Solar Panel (Model G2G1770-HAD) is a high-performance solar module designed for residential, commercial, and large rooftop solar systems. It uses advanced N-Type TOPCon technology with 144 half-cut monocrystalline cells and 16 busbars, delivering superior efficiency and excellent performance even in low-light conditions.
The dual-glass bifacial design allows the panel to generate additional energy from reflected sunlight on the rear side, increasing overall power output. With 1500V system voltage support, IP68 junction box, and strong load resistance, this panel is built for long-term reliability and durability.
It is ideal for on-grid rooftop solar systems, commercial solar plants, and large residential installations.
