Show series description

The Canadian Solar TOPBiHiKu6 series is designed to maximize energy gain in installations where every square meter counts and ensure stable production year after year. The key advantage of this lineup lies in combining N-type TOPCon cells with a bifacial structure, enabling the real utilization of reflected light from the ground surface—particularly in ground-mounted PV farms on light-colored surfaces, membrane roofs, or with appropriately selected mounting infrastructure. These modules focus on low degradation (without typical LID losses related to boron) and resistance to phenomena such as PID, translating to more predictable yields and lower long-term operational risks. The application of multi-busbar architecture improves current collection and minimizes the impact of micro-cracks, thereby enhancing reliability in challenging conditions. The TOPBiHiKu6 series is an excellent choice for PV farm investors and the C&I segment, seeking to reduce LCOE and system costs thanks to its high power density and robust module durability.
