Monocrystalline photovoltaic panel Longi 450 W

Positive power deviation: 0 ~ + 5W guaranteed

High module efficiency: 20.9> # / p ###

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

Resistant to the toughest conditions: tested salt spray and ammonia

Solid frame: (35 mm) mechanical strength 5400 Pa for snow loads and 2400 Pa for wind gusts
