Longi solar panels 540 watt 545 watt 550watt longi 540w 545w 550w solar panel

Lowest LCOE solutions for ultra-large power plants，Improved packing density, reliability and conversion efficiency LONGi's smart soldering technology uses integrated segmented ribbons. The triangular section maximizes light capturing while the flat section reliably connects cells with reduced gap. Smart soldering technology reduces the tensile stress of the cell by 20%, enabling higher reliability.P-type module with lowest LID LONGi products use gallium-doped PERC cells. Better LID performance with stable, long-term power generation.
