World-Class Manufacturing
Every LONGi panel is manufactured in our vertically integrated facilities — from silicon ingot to finished module — under ISO 9001 quality management. Our factories span millions of square metres across China, Malaysia, and Vietnam, producing over 100GW of solar modules annually with zero compromise on quality.
Innovation at the Core
LONGi continuously pushes the boundaries of solar science. From PERC to TOPCon to HPBC 2.0, every generation delivers more power, longer life, and better performance in real-world conditions including Pakistan's heat and dust.
Hybrid Passivated Back Contact eliminates metal lines from the front surface — delivering record-breaking efficiency up to 24.8% and stunning all-black aesthetics for premium rooftops.
LONGi guarantees less than 0.4% annual power degradation — the lowest in the industry. Your panels will still produce over 87% of rated power after three full decades of operation.
Engineered to withstand extreme heat, monsoon rains, heavy dust, and voltage fluctuations. LONGi panels are tested beyond IEC standards to ensure reliable output under Pakistan's toughest conditions.
