Up to 100% Bifaciality: Huasun’s Kunlun Series HJT Modules Achieve Exceptional Power in Vertical PV Applications

Huasun Energy, the leader in high-efficiency heterojunction (HJT) solar technology, proudly unveils its Kunlun Series HJT solar modules, a next-generation product with bifaciality approaching 100%, designed for vertical photovoltaic (PV) installations. It marks a major step toward solving land-use constraints while boosting energy yield, project economics, and system reliability.

Huasun Chairman and CEO Xiaohua (Jimmy) Xu emphasized the industry’s growing need for high-efficiency solutions in constrained environments. "Traditional PV systems face increasing land limitations and electricity price fluctuations. The Kunlun Series introduces a revolutionary approach by optimizing revenue with ‘dual-peak power generation’ in vertical installations, enhancing energy security and economic returns." Xu stated.

In AgriPV, Huasun collaborates with Germany’s Next2Sun on vertical PV projects, including a 5.2 MW installation in Merzig-Wellingen. “Huasun HJT modules boost performance by reducing snow and dust impact while capturing reflected sunlight, exceeding our power generation expectations by 12%,” said a Next2Sun project manager. “Their bifacial symmetrical design enhances solar absorption, improving vertical PV efficiency while minimizing light pollution, noise, and land disruption for seamless, low-impact integration.”

A 96.8 MW AC Agri-PV simulation in Blankenfelde, Germany demonstrates that Huasun’s 720 W HJT modules (23.2% efficiency) outperformed TOPCon panels, boosting operating hours by 7.91%, reducing land use by 10 hectares, and cutting BOS costs by 1.92%. These gains led to an 8.72% lower LCOE and a 3.76% higher IRR, solidifying Kunlun Series’ edge in vertical solar application.

In addition, Huasun Kunlun Series HJT solar modules are engineered to optimize performance across diverse space-constrained environments, including transportation systems, buildings, offshore locations and more. With ultra-low degradation rates (≤1% in the first year, ≤0.3% annually) and an optimized -0.24%/°C temperature coefficient, they ensure long-term efficiency. Their advanced encapsulation technology—featuring EVA, light conversion film, butyl adhesive, and glass-glass design—enhances durability, maintains stable power output, and lowers O&M costs, making them a reliable solution for vertical PV applications.
