It still doesn't make sense because of the power density. The size of the solar array you would need is completely impractical. Even a "large foldable solar panel" isn't going to cut it. Most satellites are relatively low power and even then the size of the solar arrays they have relative to the volume of the satellite is massive. Something as energy hungry as a data center pretty much demands a "small" nuclear generator to power it and the practicality of getting that into orbit nevermind the issues when it eventually de-orbits makes that a nonstarter.
