XUANCHENG, China, Nov. 28, 2025 — Huasun Energy has unveiled its Himalaya 760 HV heterojunction (HJT) solar module. This module boasts a 760 W output and 24.5% efficiency, and it’s the first in the industry to feature a 2000 V system voltage. This advancement promotes the commercialization of ultra-high-power modules, offering customers enhanced system returns.
According to Xu Xiaohua, Chairman of Huasun, the photovoltaic sector is evolving, with cost reduction at the system level and lifecycle value emerging as key competitive factors. The 760 W module is tailored for large-scale utility and desert projects, delivering higher output and high-voltage operation to optimize project economics.
Verified System-Level Benefits of 2000V System Voltage
The Himalaya 760 HV module enhances system-level optimization by increasing system voltage from the standard 1500 V to 2000 V. Simulations of a 100 MVA utility project in Hami, Xinjiang, demonstrate that, when compared to a 1500 V system, the 2000 V configuration:
- Lowers BOS costs by approximately RMB 0.1157/W (≈ US 1.6 cents/W)
- Decreases foundation pile requirements by over 5,000 units
- Improves land-use efficiency significantly
Further analysis reveals that, in comparison to a TOPCon 725 W (1500 V) system, an HJT 760 W (2000 V) system provides:
- BOS cost reductions of RMB 0.1521/W (≈ US 2.1 cents/W)
- BOS savings of approximately 11.95%
- A project IRR increase of 0.86 percentage points
These performance improvements directly result in improved investment returns for large-scale solar projects.
Advanced Design for High Efficiency and Scalable Manufacturing
The Himalaya 760 HV incorporates several design upgrades, such as a 132 half-cell dual-string architecture, large-size silicon wafers, negative spacing design, and high screen coverage. With a 95.8% active area ratio, the module achieves roughly a 20 W power gain and a 0.66% improvement in efficiency.
To ensure safety during ultra-high-voltage operation, the module uses a unique butyl edge-sealing process, which enhances insulation without affecting efficiency. It is fully compatible with existing high-efficiency production lines, requiring only minor equipment adjustments for rapid and stable mass production.
The Himalaya 760 HV, with its 760 W output, 24.5% efficiency, and 2000 V platform, sets a new standard for next-generation utility PV systems. “760 W is not an endpoint, but a new starting point,” Chairman Xu stated. “This platform will continue evolving toward higher power, higher efficiency, and higher value for the global clean energy transition.”
