Show series description

The Astronergy ASTRO N7s 2.0 Bifacial (CHSM54RN(DG)/F-BH) series was designed for maximum yield from the same rooftop surface – without compromising on durability and aesthetics. These bifacial glass-glass modules feature n-type TOPCon 5.0 cells, which better withstand high operating temperatures and experience slower degradation over time, translating to more stable energy production year after year.

A key highlight is the ZBB (zero busbar) technology, which minimizes shading on the cells and resistive losses while enhancing resistance to microcracking. In practical terms, this ensures reliable performance in real-world installation conditions and under mechanical stress.

Compared to competitors, the series stands out thanks to the Light Redirecting black film, which optimizes light distribution and helps better utilize sunlight, and the format facilitating transportation and installation on roofs with limited space. This is a smart choice for residential and premium segments, where performance, appearance, and long-term reliability are key.

Panels from the same series differ mainly in power output while having identical dimensions. Learn why →
