Features
- High-efficiency Hetero-junction Solar Cells (efficiency ≥ 24%) are laminated inside with excellent weak-light performance and superior Power Temperature Co-efficient, which enable the solar panel to achieve 5%–10% more power.
- Unique Super-wire Flexible Interconnection Technology ensures an excellent ability to resist cell cracks and impact force. Even under extreme conditions, solar cells and the panel still generate power as long as they are not destructively damaged.
