HJT Photovoltaic Panels

Utilizing next-gen N‑type HJT 2.0 architecture with gettering and single‑side μc‑Si processing, these panels achieve exceptional efficiency (up to 23.02 %) and deliver high power output.

HJT High-Efficiency 480W 490W 500W
Bifacial PV Modules

HJT (Heterojunction Technology) panels are next-generation N-type solar modules that combine crystalline silicon wafers with thin layers of amorphous silicon to form a high-efficiency cell structure. This hybrid design delivers very high efficiency (over 23%), excellent low-light performance, and minimal power loss over time. HJT panels are typically bifacial, capturing sunlight from both the front and back sides, which increases total energy yield, while also offering lower temperature coefficients and longer lifespan compared to conventional PERC panels.

Advatnages

  • Wide Capacity Range – Available from 430 W to 715 W, covering both sleek all-black residential modules (430–450 W) and high-power bifacial modules (625–715 W) for commercial and utility projects.

  • Advanced HJT 2.0 Technology – N-type HJT cells with micro-Si layers deliver very high efficiency (up to 23.1%), improved temperature performance, and minimal power degradation.

  • Bifacial Power Boost – Up to 90% bifaciality, enabling panels to capture sunlight on both sides and significantly increase total energy yield.

  • SMBB & Half-Cut Cell Design – Super multi-busbar and half-cut technology reduce resistive losses, enhance current collection, and maximize long-term performance.

  • Superior Durability & Reliability – Dual-glass structure with excellent PID resistance and lower annual degradation ensures reliable operation for decades.

  • Industry-Leading Warranty – Backed by a 25-year product warranty and 30-year power output warranty, guaranteeing consistent and long-lasting energy generation.

  • Lower System Costs – High efficiency means fewer panels are required to achieve target outputs, reducing balance-of-system costs (brackets, inverters, land, cables).
