If you have solar panels on a rooftop that would otherwise be cooked by the sun, aren't you also saving on the amount of power required for air conditioning?
If you're trying to heat the building - not so much.
In the case of a datacenter, I don't think that heating the building is that much of a concern.
Average solar insolation is more like 5 sun-hours/day, not 8, in good locations. Much less in places like Germany.
Don't tell that to Fox news - everyone knows that Germany gets LOTS of sunshine.
Your datacenter takes 1 MW/h. You receive roughly 8 hours of usable sunlight, so you need 3MW/h capacity of solar panels to produce the power you need
Whatever the soundness of your arguments, you immediately discredit yourself by using "MW/h" as a unit of power. That's like saying that your new car is rated at 500 horsepower/minute, or has a fuel consumption of 32 mpg/hour. What are those even supposed to mean?
And, no, the corrected unit is not MWh, or "megawatt-hour". That is a unit of energy (a bulk quantity), not power (the rate of energy production or consumption). The proper unit for referring to the size of a PV array, or any electrical generation facility, is "watts" or some SI-prefix thereof.
It would do nothing to curb criminality
Some kinds of criminality would be harder. If you have to move, say, €10 million in cash, whether you do it in €500 bills or €50 bills makes a large difference. In the first case, you only have to move 20,000 pieces of "paper" (a stack about 2 m tall). If you are constrained to €50 bills, you have to move 10x as much cash. Now, instead of a single briefcase that can easily be carried onto a railcar, you need a few duffel bags.
Not that this is an insurmountable obstacle to criminals - it just makes certain transactions harder to execute and hide.
They're trying to duplicate something they saw on a sci-fi TV show, thats primary use was exploration of alien planets
No, the tricorder's primary use was exposition, not exploration.
TV Show Watcher: What the heck is going on there?
Star Trek Character: (consults tricorder) There appears to be a radiation surge from other there, indicating a portal will soon appear and introduce this week's source of conflict.
TV Show Watcher: Thanks, informative tricorder!
It's not about how attractive they are. But how traditionally they are dressed. Which for many people contrasts with space exploration.
Well, although a sari is a wonderful outfit, the flowing fabric would probably just get in the way in zero-g.

My keys are metal. They don't bend.
Ah, but do your keys have a 5.7" screen?
