Hi!! I am designing a PV system in 4 warehouses. Each building has its own tilt and azimut, and due to the limitation of PVsyst on the creation of sub-arrays (8 maximum) I cannot calculate the generation of the 4 warehouses together. So I did 4 different PVsyst, one for each building. But now I have to provide the PR of the whole project. The PR is calculated as follow: PR = E_Grid / (GlobInc * PnomPV) For E_Grid and PnomPV I can sum all the energy and the total power peak installed, but for GlobInc is not possible I thought to do the weighted sum of each PR using the E_Grid of each building. Do you think this can be the solution? Thanks for your help!
