Monocrystalline photovoltaic panel Longi 405 W

Positive power deviation: 0 ~ + 5W guaranteed

High module efficiency: 18.7%

Slower power degradation thanks to Mono PERC technology with greater resistance to LID degradation: first year <2% and 0.55% in years 2-25

Increased energy efficiency due to excellent efficiency achieved with low intensity of solar radiation and extremely favorable temperature coefficient

PID resistance thanks to the optimization of the production process and the choice of solar cells
