1. Adopting multi-main shed (MBB) half-sheet technology, the output power is away from 670W, and the conversion efficiency of the module reaches 21.58%.
2. Anti-PID performance. The PID (Potential Induced Degradation) resistance authority test(85°C/85% RH, 96 hours) under the harsh conditions of the industry minimizes the chance of degradation caused by the PID.
3. 12 main grid cell, with stronger current collection capacity and more stable power output.
4. Mechanical load. Certified for wind load of 2400 Pa at the back of the assembly and snow load of 5400 Pa at the front.
5. Excellent low light power generation performance. Excellent electrical performance output under low light conditions.
6. Low light attenuation. Rigorous ATLAS steady-state light testing ensures excellent photoluminescence performance for each batch of modules.
7. Rigorous EL testing. Spatial resolution is less than 0.5 mm,and more than two EL tests before and after to ensure zero defects inside the component.
8. Fully automated component production line. Guarantee 100% online production 100% online inspection to ensure consistent product quality.
