The Longi LR7-72HVH-635M is a 635W back-contact (BC) module from the new Hi-MO X10 Explorer series, delivering up to 23.5% efficiency.
Hi-MO X10 uses LONGi's TaiRay wafer and second-generation back-contact cell technology - all busbars sit behind the cell, so the full front face collects light. The result is more watts per square metre, better low-light and high-temperature behaviour, and a cleaner all-black look. Backed by a 15-year product warranty and a 30-year linear power warranty (under 1% first-year degradation, then 0.35% a year - 88.85% output guaranteed at year 30).
