Lower operating temperature

Better temp. coeff.

Better temperature coefficient and loweroperating temperature of HiDM resultfrom its internal resistance.

9Canadian Solar Inc.

Cell crack propagation stopped by cell edge.

HiDM cell damage impact area potentially reduced by up to 83%. Enhance the

reliability of PV module.

Minimize micro-cracks, enhance the long term reliability
