Advanced N-Type TOPCon Performance

The TOPBiHiKu6 series uses advanced N-type TOPCon cells designed to improve long-term production and reduce degradation over time. Compared to traditional PERC modules, N-type technology offers improved temperature performance and stronger long-term energy retention.

The bifacial dual-glass construction allows the module to generate additional power from reflected light on the rear side of the panel. Depending on mounting conditions and ground reflectivity, bifacial gain can significantly increase total energy production.
