Note: LONGi Hi-MO X10, N-Type BC (HPBC 2.0). 640 W at 23.7% module efficiency. Bifacial dual-glass with 70% bifaciality - the back face adds that share of the front output when it has something bright to reflect off, so it is worth real money on a white roof or light gravel and close to nothing on a dark one. Temperature coefficient -0.260 %/°C. 15-year product warranty, 30-year linear power warranty. Price shown is built from a Pakistani per-watt rate, not a quote for this exact model: Rs 42 per watt, which at 640 W works out at roughly Rs 26,880. The rate was collected on 16 September 2026. Panel rates in Pakistan move with the dollar and are quoted per watt, so treat this as a guide to negotiate around rather than a fixed figure, and always confirm the day's rate with the dealer.
