Its real use case is going to be for nuclear power, either fission reactors or radioisotope power systems. Not solar electric. It turns out solar concentrators and reflectors are pretty difficult and fragile. If you have enough sunlight, solar will almost always be preferred. Note, I work with these systems at NASA.
