I doubt that wireless energy transmission at this scale and distance will ever be practical. It will probably never be economic compared to terrestrial panels and batteries. If/when we build space elevators, then orbital solar might make sense to use the tether to transfer power. Even with the lower cost of putting mass in orbit, I don't think it'd be any cheaper than terrestrial solar. Besides, by the time we figure put space elevators, we'll already have commercial fusion, right?
