Warranty:Based on the advanced mono wafer and anti-LID technology, LONGi offers a first-year power warranty of ≥98% for PV modules.
Bifacial PERC: For a bifacial PERC cell, the Al back surface field is replaced by Al grid, hence render the majority of rear side transparent which enable the cell to absorb light and generate electricity from both sides.
Half-cut cell technology: To cut the cell into two seperate parts by mature infrared laser, hence halve the working current. The thermal loss on the
ribbon will be remarkably reduced and the module's power increases by 2%. The reliability of module is also enhanced.The combination of half-cut cell technology and bifacial module can amplify the gain over the effect of current-reduction.
