Price shown is built from a Pakistani per-watt rate, not a quote for this exact model: Rs 37 per watt, which at 690 W works out at roughly Rs 25,530. 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.
