Note: Canadian Solar TOPBiHiKu7, N-Type TOPCon. 645 W at 22.8% module efficiency. Bifacial dual-glass with 80% 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 -0.29 %/°C. 12-year product warranty, 30-year linear power warranty. Price shown is a market range built from Pakistani per-watt rates, not a quote for this exact model: Rs 42 to Rs 46 per watt, which at 645 W works out at roughly Rs 27,090 to Rs 29,670. The low end is the wholesale rate published on 11 August 2026 and the high end a retail rate list from 24 August 2026. Panel rates in Pakistan move with the dollar and are quoted per watt, so treat this as a band to negotiate inside rather than a fixed figure, and always confirm the day's rate with the dealer.
