Also, a big part of the inefficiency in conventional power collection (in the case of solar) is transmission losses in the power lines. This converts light directly into microwave energy that can then be transmitted without power lines. That's a game hanger, just like wifi is to ethernet
And that doesn't include the cost (both money and carbon) of launching all the collection and transmission equipment into space in the first place.

The first generation of space power delivery is probably going to be passive as well, maybe a low power echo signal for target acquisition, but not complicated protocols to negotiate power or data flows.
