Hello, We are currently trying to model the differences in output of an array with 2 strings - once facing west and one facing east. We would like to know the difference in performance when they are connected to either a single MPPT, or separate MPPTs. We are expecting to see a small reduction in power when using a single MPPT. The results we are currently getting is a slight increase in performance when using a single MPPT - only an additional 2kWh over a year with a 4kW system. Although this is negligible, it would indicate the simulation is not accurate as there would be more loss using only a single MPPT. This would indicate the simulation does not represent the situation we are string to simulate! Is it possible to simulate this in PVsyst? Regards, Jono
