Warning for module layout in 1MW projects

[Jehad Adeeb]

Dears,

Can you please explain what is the technical reason behind this warning?

It is computationally intensive, and PVsyst will have difficulties with larger sites. If they are large enough, it will not work at all. 1MW is some threshold I imagine they determined in the past based on performance. In my experience, sites larger than 1MW can use the module layout method; however there still is an upper limit for how large a site can be processed, and it may depend on the nature of your model, computer system, etc., in addition to the software.

Thanks @dtarin for your answer.
