It's not physically impossible. But the engineering reality isn't promising.
You'd need micro-meter alignment accuracy across the constellation for optical observation. For radio observation it might be possible - but I'm not sure if it would be useful.
Launching complimentary ordinary space-telescopes would also be good PR.
There are enough panels available to do both and there is no overlap in financing for both. So just do every installation that is economically viable, they don't compete for money or panels.
How expensive is it to not build a single-purpose building like an office or housing condo in the first place, but a true multipurpose building that can do both well with manageable retooling costs?
Some of that is lost due to regulatory 70% limits during peak times.
Also the rated capacity is for some synthetic sun conditions. I have no idea what's the conversion factor between ideal sun in Germany and the PV rating sun.
The control group is needed to measure process properties / systematic error.
It does not need to be a placebo group. Previous data at the same hospital does not help because the regular medicine does not run according to study protocols.
