Huasun Energy has introduced its Himalaya 760 HV heterojunction (HJT) solar module, marking an advancement for the company in ultra-high-power module commercialisation.
The new module delivers an output of 760W, an efficiency of 24.5%, and features an industry-first 2000 V system voltage, designed to boost system returns for customers.
Huasun’s Chairman Xu Xiaohua commented that the photovoltaic industry is now “entering a new phase in which system-level cost reduction and lifecycle value are becoming the primary drivers of competitiveness.”
The 760W module is primarily designed for large-scale utility and desert-based projects, leveraging its high output and high-voltage operation to maximise project economics.
The key innovation is the upgrade from the current industry-standard 1500 V system voltage to 2000 V. This modification, as demonstrated in a simulated 100 MVA utility project in Hami, Xinjiang, unlocks substantial system-level optimisation.
Compared with a 1500 V system, the 2000 V configuration is shown to reduce BOS (Balance of System) costs by approximately RMB 0.1157/W (≈ US 1.6 cents/W), cut foundation pile demand by more than 5,000 units, and significantly improve land-use efficiency.
Further analysis comparing the HJT 760W (2000 V) system with a TOPCon 725W (1500 V) system revealed BOS cost reductions of RMB 0.1521/W (≈ US 2.1 cents/W), resulting in approximately 11.95% in BOS savings and an increase of 0.86 percentage points in the project’s Internal Rate of Return (IRR).
These performance gains translate directly into stronger investment returns for utility-scale solar projects.
The Himalaya 760 HV integrates several design upgrades, including a 132-half-cell dual-string architecture, large-size silicon wafers, negative spacing design, and high screen coverage.
The module achieves an active area ratio of 95.8%, contributing to an approximate 20W power gain and a 0.66% efficiency improvement.
To guarantee safety under ultra-high-voltage operation, the module incorporates an innovative butyl edge-sealing process to enhance insulation without compromising efficiency.
The design is fully compatible with existing high-efficiency production lines, requiring only minor equipment adjustments for mass production.
Combining 760W output, 24.5% efficiency, and the 2000 V platform, the Himalaya 760 HV establishes a new benchmark for next-generation utility PV systems. Xu concluded: “760W is not an endpoint, but a new starting point.
This platform will continue evolving toward higher power, higher efficiency, and higher value for the global clean energy transition.”
