Helios 3D file import to PVsyst

[denizurla]

Hello, I am trying to import a Helios 3D file into the PVsyst and execute a simulation. I can import the Helios file of a 6-7 MWp PV system, however it crushes down, when I try to simulate it. I can define the field partitions, I can create the table "Module Strings Shading Factor", which takes a very long time and sometimes PVsyst crushes during the process.

Which size of PV plant designs would you recommend to use for this import process, in order work with the simulations fluently?

Thanks,

Deniz

Some few MW is really a limit for the version 5, because the calculation time goes with the squarte of the number of elelmets.

In the version 6, the shading factor calculations have been optimized. For big systems the time is improved by a factor of 10 or more.
