It's really cool that SpaceX has the ability to put stuff in orbit without it being a billion-dollar event. But I don't see any advantage to having unmaintainable tech in orbit, where all you can do is throw away an entire satellite.
What's the advantage? You can get solar power here on earth. We're not running out of land; we could put them in the middle of nowhere if we wanted, for way less than orbit.
I just can't think of any reason why we'd do this, other than "it's cool". Which, fair, but it seems like a waste.
Combine that with the 5-10x higher production from being in constant unfiltered sunlight, and lack of need for storage, and it could well be much cheaper to make the power in space.
