I tried looking through all of the questions on this board for a similar one and didn't see it; hopefully this isn't a repeat.

I am currently in the process of pulling together the design submittal for NCv2009. The Owner is trying to get a PV array donated to the project, so at this time is is unclear how large the array will be. The energy modeler has estimated 10kW (the minimum size it will be, which meets the credit intent for 1%) but the roof has been sized for an array as large at 30kW. Question: Should we wait until construction to submit EAc1 and EAc2 when we know the array size for sure, or should we submit them both in the design phase assuming the 10kW and resubmit in the construction phase if the Owner is able to get a larger array donated? Would there be a fee for changing the array size later, since this would be something that happened during the course of construction, not a calculation change? A side note, we are barely able to certify the building, so we are counting points very closely. I'd like to confirm as many points as possible in the design submittal so we know where we stand, but obviously we don't want to incur any extra costs for the Owner.
