Orion solar panels

It seems to me that the Altair and Orion spacecraft, in their journey from Earth to Moon will need the same thermal control as the Apollo spacecraft did. This was achieved by a ‘barbeque roll’ of the spacecraft, perpendicular to the direction of the Sun meaning that no part of the structure got too hot or too cold.

Now, Altair/Orion (let’s just call it Orion shall we?) will have the same problem, and I presume a similar solution. However, with the winglike solar panels on Orion will it be simple? I suppose it might be possible to drive the panels so that they were always facing the Sun, but with current design concepts it looks awkward, with some kind of universal joint being necessary.

Perhaps the heat management of Orion will be different so that the passive thermal roll is unnecessary, or the solar panel orientation is easier to control than I suppose (and I’m no engineer). I do know that a single axis rotation such as that achieved by the Apollo crews was very difficult to manage, but guess it would be simpler with modern avionics.
