Hi, a solar PV consultant gave me an output of their simulation, in which show probability distribution diagram of Solar PV production. The peak is 79 MWh/year with Probability of 50 - P50 (we would have it 1 year out of every 2 year). P75 is 75 MWh, P90 is 73 MWh. Now, I don't know which production should I take for this credit. Can I use the peak production 79 MWh with P50.

I highly appreciate any advice and comment.
