SF-160S
Mono-crystalline Solar Module
- 1.Higher electrical power output
- The utility rate of PV system space become more efficient, and the module output power is further improved. Suitable for the electrical power generation system of residence, commerce, power station, etc.
- 2.Less power loss
- Adopt anti-reflective glass to increase light absorption while making the module have the function of self-cleaning under the condition of rain, this will effectively reduce the harm caused by the grieshoch.
- 3.The more outstanding generation performance in the condition of weak light. (Morning, Evening, Rainy Days, Foggy Days)
- 4.The stronger anti-pressure ability.
