2.High power output and highest conversion efficiency of 21.90%
3.Anti-reflective and anti-soiling surface reduces power loss from dirt and dust
4.Outstanding Performance in low-light irradiance environments
5.Excellent mechanical load resistance: Certified to withstand high wind loads (2400Pa) and Snow loads (5400Pa)
6.Positive power tolerance: 0~+5W

1.New cell string layout and split J-box location to reduce the energy loss casused by shading between modules
2. Low thermal certificates for greater energy production at high operating temperature
3. Low cell connection power loss due to half-cell layout (144 monocrystalline pv module)
