Product overview

Back-contact cells, 640 to 670 W.

LONGi builds the Hi-MO X10 Scientist on its HPBC 2.0 back-contact cell, TaiRay wafer and a busbar-free (0BB) cell structure, and names resistance to shading among the series characteristics. The LR7-72HVH-xxxM has 144 cells in a 2382 × 1134 × 30 mm frame; the HVH type uses a single 3.2 mm glass, the HVD type two 2.0 mm panes with a bifaciality of 70 ± 5 %.
