Here is Kaarous' original comments in full:

Hey look , literally the one thing I'm a subject matter expert in besides eating pussy.

I've helped design modern solar fins for spacecraft. To put it mildly, every single part of this meme is wrong, and whoever wrote it should contact their high school about getting their money back.

and:

I really can't get into because I don't want to accidentally disclose classified information. Anything to do with spacecraft is classified left and right seemingly at random. There's a reason I don't work for the feds anymore.

That said I'll say this. Terrestrial solar systems don't work in the cold for entirely different reasons. Comparing them to this is like asking why a paper airplane doesn't work when it gets wet but a jumbo jet does.

Here are the relevant parts:

And here's a very specific part of the above that's the key information with bolding for emphasis:

Now that you've been walked through this, I would like to ask you to please point out where Kaarous has said that the panels on the ISS are classified information? Because what he said is that what is and isn't classified is often arbitrary and he doesn't want to risk being liable for saying something he shouldn't. It's actually a bit vague, which is funny that you would then try and pin a rather specific claim on him.

Gonna go out on a limb here and say that maybe you've got a chip on your shoulder and you're trying to prove Kaarous wrong before actually reading and responding to what was said. Almost like this is just you having a rather childish spat.
