Show series description

The Huasun Kunlun G12R (HSN-210R-B132) series was designed specifically to maximize energy yield in conditions where traditional modules lose potential – namely during light reflections, difficult exposure, and variable daily operation. The key differentiator is the combination of dual-sided construction with HJT n-type technology, which operates stably in high heat and minimizes long-term losses. The module also utilizes rectangular G12R cells, enabling it to better "fill" the surface area and increase power density without needing more panels. In practice, this translates to fewer compromises when designing string layouts and easier achievement of high yields on limited surfaces.

The Kunlun G12R targets industrial installations and PV farms, but it also performs well in projects where morning and afternoon energy is crucial. An additional advantage is its enhanced mechanical durability and features improving performance under diffuse light, setting the series apart from many standard bifacial modules.

Panels from the same series differ mainly in power output while having identical dimensions. Learn why →
