Co-location: what are the costs and benefits of DC-coupling?

This, alongside reduced cost efficiencies elsewhere, can erode any cost benefits from DC-coupling. Therefore, the preference for AC-coupling versus DC-coupling may come down to the operational benefits of each. For DC-coupling, the key to this benefit is in oversizing the solar farm - and the value of the subsequent "clipped" energy.
