Blocking diodes

I'm just about to fit two Victron 305w panels in parallel. Do I need to fit blocking diodes anywhere in the circuit?

if you are using the victron MPPT regulators then No as they already protect against feed back to the panels

Isn’t it so that if one panel is shaded and the other is not in a parallel installation, there is current moving from the non-shaded to the shaded if no diodes are not installed?

Yes 100/50. As I thought. I assume the panels have some sort of built in diode also. Thank you
