Wholesale 17.4%-17.5% efficiency E-ton multicrysalline solar cell 3BB with good price

- Up to 20.0% efficiency, one of the highest performing mono crystalline cells on the market

- Three bus bars boosts current collection over the entire cell area, leading to higher fill factors and MORE POWER

- Blue anti-reflecting coating allows more sunlight be captured and converted to electricity

- Finer, closer fingers improves charge collections for improved energy yield

- Lower light-induced degradation leads to greater power output over the entire module lifetime

- All solar cells are tightly classified to optimize output of module

- Maximum yield and longevity due to hotspot prevention

- Premium appearance results in a highly uniform and aesthetically appealing module
