Utilizing Revolutionary N-Type TOPCon Solar Cells
Generate even more energy
With N-Type TOPCon solar cell technology, we've raised the bar on conversion efficiency, reaching heights of 25%. Generate and store more sunshine than ever before.

Why N-Type TOPCon solar cells are better ?
Up to 25% conversion efficiency
Monocrystalline Silicon Solar Cells: 21%-23%
TOPCon Solar Cells: Up to 25%
Performs well in low-light 0.5-1.0% higher power generation rate than P-PERC
Adapts to dull lighting conditions, maintaining a high power generation rate even on overcast days.
High energy conversion in scorching temperatures*
Monocrystalline Silicon Solar Cell: 11.7%
TOPCon Solar Cell: 9%
Up to 30-year lifespan**
Monocrystalline Silicon Solar Cell: 25-year
TOPCon Solar Cell: up to 30-year
*When the surface of the solar panel reaches 55℃, TOPCon Solar Cell temperature coefficient is 23% less than that of the Monocrystalline Silicon Solar Cell. **The service life depends on the actual use.
Coated with Highly Protective Lamination and Tempered Glass
Designed to weather any storm
Built with a robust anti-corrosive aluminum frame, it's designed for years of solar-ray collection. Its TOPcon cells are coated with highly protective lamination and tempered glass and comes with an IP68 waterproof rating to enhance performance and offer long-lasting durability.
