Canadian Solar HiKu7 665W (CS7N-665MS)

Note: Canadian Solar HiKu7, P-Type Mono PERC. 665 W at 21.4% module efficiency. Mono-facial - front side only, glass over backsheet. Temperature coefficient -0.34 %/°C. 12-year product warranty, 25-year linear power warranty. This is a P-type mono PERC panel, and the manufacturer has superseded it. Canadian Solar's and JA Solar's current catalogues list only N-type TOPCon and HJT modules; PERC lines like this one are being run out. They are still widely sold in Pakistan as the budget tier, and there is nothing wrong with them - but the temperature coefficient tells you what you give up: -0.34 %/°C against -0.29 for TOPCon, so on a 45 °C Pakistani roof this panel loses roughly 1.7% more of its rated output than an N-type of the same wattage. Efficiency is also 1.5-2 points lower, so it needs more roof area for the same kW. Buy it on price per watt, and check the warranty term before you do. Price shown is a market range built from Pakistani per-watt rates, not a quote for this exact model: Rs 36 to Rs 40 per watt, which at 665 W works out at roughly Rs 23,940 to Rs 26,600. 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.
