During the OFF times there is no power produced and no heat to dissipate! ie @ Voc there is no power - open circuit.

R,
The MPPT controller does open.close switches to limit current out in order to hold a specified regulation voltage.
Hope this is what you were looking for
Subject do MS MPPT controllers use PWM to limit voltage out
Description:
Do MPPT controllers go into PWM during absorption or float, ie is there a duty cycle (on/off) or does the panel operate at the far left of a IV curve?
Thank you,
