Module Excellence
Multi Busbar Technology: Better light trapping and current collection to improve, Effectively improve the module’s power output and reliability。
Higher output power: Module output power increased to550W.
Low light performance: The special solar cell technology has excellent low light power generation performance.
Better resistance to hot spots: The use of half cell structure and special circuit design is less shade loss, with better temperature coefficient and thermal spot resistance ability.
Adaptability to harsh environments: High-performance materials are suitable for coastal, farm, desert, and other harsh environmental conditions, the glass surface is anti-reflective and easy to clean, minimizing power generation losses caused by dirt and dust.
