Simulations are extremely slow after 7.3.4 update

[Murat Karakum]

I updated to 7.3.4 today and I noticed the simulations are unbearably slow!!! I did revert back to the previous version but it is still extremely slow nothing changed! yesterday it was running smoothly in less than a minute and now its more than an hour and it doesnt move forward the bar moves backwards too!! Its unbelievable.

Hi, if reverting back to a previous version did not change the simulation speed, it probably is related to some parameters in your project.
We'll gladly have a look at what is causing the slowness. You can send us your project for review at support@pvsyst.com.

Hi Moderator, can you help me with the same problem? My simulation onVersione 8.0.8 is extremely slow. Can I send you the project?
This is a big project but 2 hours for shadows and 4 hour for 15% of simulation are too much, so I stoped the simulation.
Plese help me with a rewiev of the project.

P.S. Where Can I share the project.

Best regards and Thank you
