If the habitat is segmented and connected with non rotating couplers then you could mount solar on each coupler. The design would then be multiple identical potentially self sufficient modules that can be assembled into a large colony and expand as needed. Wouldn’t have much of a horizon though so it would feel a bit claustrophobic.
