Canadian Solar HiKu7 CS7N-660TB (660 W)
The Canadian Solar HiKu7 CS7N-660TB is a 660 W solar module built on TOPCon technology (n-type TOPCon (Tunnel Oxide Passivated Contact)). It delivers a maximum-power voltage (Vmp) of 37.8 V at a maximum-power current (Imp) of 17.46 A, with an open-circuit voltage (Voc) of 44.8 V and a short-circuit current (Isc) of 18.6 A under Standard Test Conditions (1000 W/m², 25 °C, AM1.5G). Conversion efficiency is 22% across a 2384 x 1303 mm footprint.

Technology & Performance Notes
TOPCon is the leading n-type technology for high efficiency with strong low-light and temperature behaviour. At 22% module efficiency the Canadian Solar HiKu7 CS7N-660TB converts 22% of incident solar irradiance into DC electricity, putting it in the premium efficiency tier for its class. The 212.2 W/m² power density determines how many watts fit on a given roof or field area.
String Sizing & System Notes
When wiring the Canadian Solar HiKu7 CS7N-660TB into a string:
- Keep the string Voc (temperature-corrected to the coldest expected cell temperature) below the inverter’s maximum DC input voltage.
- Keep the string operating Vmp within the inverter’s MPPT window across the expected temperature range.
- Size fusing and conductors against Isc (18.6 A) with the standard 1.25x safety factor.
