Canadian Solar 400W Mono PERC


Canadian Solar‘s new high performance panels have been designed for high voltage systems with up to 1500 V DC. This enables a 50% increase of string length, reducing the BoS costs of your solar system while improving the system performance through a reduction of wiring losses.



  • IP68 split junction boxes:
  • Better heat dissipation & higher safety


  • Optimized cable length: Simplified wire fix & reduced energy loss in cable
