How could that possibly be the case? The current best commercially-available solar panels are 20% efficient. Last-gen stuff is 10-15%.

Well if you put those solar panels right up against the sun, they'd be much more power dense. But for the moment building a nuclear reactor on earth is a significantly easier engineering challenge than building a solar plant on the sun.
