In LEED, energy savings are calculated in monetary amounts rather than energy units. I'm working on a project in Europe where feed-in-tariffs are the official energy rate for energy produced from solar PV panels, which is at a premium to regular electricity rates. Since PVs would contribute to savings in kWh, but an even greater savings in monetary units, how should this be treated when modeling in the baseline versus the design case? For EAc2?

You have two options to calculate renewable energy cost. Use the virtual rate calculated by the energy model for EAc1 or the local utility rate structure. There is an option on the LEED Online form to select one or the other. Sounds like you are better off using the local rate structure. The same cost value should be used in both EAc1 and EAc2.
