The big advantage is the PV in space doesn't experience night (aside from very rare eclipses by Earth in geostationary orbit, which happens for a short period twice a year). If we had laser power beaming it might make sense to put large PV installations around the Earth-Sun L2 point, so the power could be beamed to collectors on Earth's night side. Each beam would serve a series of collectors as the Earth rotated. The market in the Pacific would quickly be saturated, I imagine.
