Land and permitting. I’m not saying the math works. Just that there are envelopes for it to.

Solar in space is a very different energy source in terms of required infrastructure. You don't need batteries, the efficiency is much higher, cooling scales with surface area (radiative cooling doesn't work as well through an atmosphere vs. vacuum), no weather/day cycles. Its a very elegant idea if someone can get it working.

Sun-synchronous orbit means there's no nightime for satellites in that orbit.
