We are certifying a Positive Energy Building, that will produce 130% of its energy consumption with solar PV.
All the energy produced with the PV will be sold to the grid.
I was wondering if we could get any credit for the PV, considering that the building produces 30% more energy than it consumes, and, thus, this "extra" 30% needs to be sold to the grid, since the building cannot consume it.
Does anybody know how to treat cases like this?
Thank you

Check the interpretations on this issue. I recall that the PV power must be fed into the building, not the grid, in order to count at all. It is possible that has changed. If my recollection is correct the fact that it produces 30% is moot.
IMO if the PV is just feeding to the grid then your building is just a big PV rack not a net positive building.
