Personally I think it is so close as to not be an issue whatsoever.
The parallel VS series calculators available online will report large losses if you plug your numbers in and IMO they are flawed and wrong in this particular scenario.
I'm sure someone will come along and school us.

I vote for FOR SURE. I dont think you could do a better match than that!
Those are both good panels to combine.
Using Vmp & Imp (not Voc and Isc)
The math of combining is:
In series you add volts and use the lowest amps.
In parallel you add amps and use the lowest volt.
After volts * amps = watts.
The penalty for combining different panels depends on the the differences in the Vmp and Inp and the way they are combined.
You only have the Voc’s listed - (and those Voc’s are extremely close) as long as the Vmp are just as close you will have very little or no penalty for combining different panels.
As you combine panels in parallel be sure and watch the amps that are flowing down the wires and make sure the wires are big enough to handle it. (Caution some panels manufacturers use 12awg wire for the wire out of the panel - if you have that wire don’t exceed its current).

Yep they are close enough, you will be fine.

Can combine solar panels 265w different voltages?
Hello guys, thanks for all the help I am receiving everytime I ask a question. Much appreciated. I have the growatt spf 3000tl lvm-es, I bought 6 Jinko solar panels 265W (VOC): 38.6 V (VMP): 31.4 V (ISC): 9.03 A IMP: 8.44 A Can I combine these panels with the: Kyocera 265W ? (VOC): 38.3 V...

You should have been able to answer this yourself.

Just put something there to stop him in his tracks, and he'll never find your real dirt.
Hey Evil Jason, you might even get away with combining in series. Based on specs. I'm not sure how different panels vary from each other under conditions other than STC.
6 of one, full dozen of the other? I assume you mean 3 strings in parallel.
Need to add up current in parallel, see if your inverter allows that much. Or does it have separate MPPT?
Design your array, series/parallel, voltage and current, and compare to MPPT specs.
Possibly 9s2p would be a better fit, possibly not.

Perhaps just a terrible memory?

Not a problem.
