Products Description
This 630W solar panel is part of our high-efficiency TOPCon bifacial module series, developed specifically for utility-scale solar power plants, commercial and industrial rooftops, and EPC-driven projects that demand long-term reliability, stable performance, and bankable quality.
Built with TOPCon technology, a 132 half-cell layout, and a dual-glass structure, this module delivers higher energy yield per square meter while maintaining excellent mechanical strength under harsh environmental conditions. For project developers and EPC contractors, it offers a balanced solution between performance, durability, and total system cost.
TOPCon Technology for Higher Energy Yield
The module uses TOPCon cells, which offer clear advantages over conventional P-type technologies:
- Lower initial degradation (LID) and improved resistance to long-term power loss
- Higher conversion efficiency across the entire operating life
- More stable performance under high temperature and low-light conditions
For projects with long investment horizons, TOPCon technology provides more bankable energy output and better alignment with financing requirements.
The dual-glass structure not only enhances durability but also enables bifacial power generation. When installed on reflective surfaces such as concrete, sand, or light-colored ground, the module can capture additional irradiance from the rear side, increasing overall system yield.
At the same time, the 2.0mm + 2.0mm tempered glass structure offers strong resistance to moisture ingress, UV exposure, and chemical corrosion, making the module suitable for coastal, desert, and industrial environments.
