Solar panel configuration.

[Doublewammy]

Hi there, I am just trying to fit 5 new panels into the existing framework, my question is, can you use different size panels, ie 3 x 100watt, 5.6 amp and 2 x 80watt, 4.4 amp panels all to be wired in parallel. They are wired to an existing Prostar 30 amp solar controller.
Your assistance is appreciated.

Yes there is no problem mixing panels of different wattage wired in parallel with a PWM controller as yours is.

With a MPPT controller it fine as well as long as the Vmp is close.
