Show series description

The Huasun Everest G12R series are HJT modules featuring rectangular, monofacial n-type cells designed to generate more energy from a single module footprint while simplifying installation design. The key advantage lies in the G12R cell geometry – it better utilizes the laminated surface area, reduces losses caused by “dead space”, and helps increase yield without adding more panels. In practice, this translates to real savings on Balance-of-System (BOS) components and easier scaling for PV farms.

The Everest G12R also incorporates solutions typical of modern heterojunction modules: HJT technology proven for long-term stability, bifacial structure supporting additional yield from the rear side, double glass enhancing durability, and advanced interconnection architecture minimizing conduction losses. This is the series for investors calculating LCOE and for EPCs seeking modules for utility and C&I projects, where high energy production, reliability, and predictable operation year after year are paramount.

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