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!

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.

Is it possible to simulate this in PVsyst?
