Unlimited Tracker and 3D scene

[Ishan31]

While simulating project with identical capacity, components, and loss factor , PVsyst has generated variable generation( E grid MWh) results for Unlimited tracker mode and the 3D scene mode .

                                    Egrid MWh         Near Shading loss : Irradiance

Unlimited Tracker      1438860                -1.8%

3D scene                    1481095               -2.4 %

I want to understand how PVsyst is generating variable results for Unlimited tracker and 3D scene mode which should not be case for identical project parameters(Pitch,1P,Other loss factors). What are the factors resulting in this variation .

Dear Ishan,

First of all, the Unlimited Tracker represents an idealized PV table layout, with all rows having exactly the same length. Most likely, your 3D scene doesn't follow this idealized representation.
Could you please send us your project by email at support@pvsyst.com, so I can check it and explain why you're seeing these differences?

Regards,

Dear Sarikaya,

I am still awaiting the response on the above topic for the project files emailed on multiple occasions at support@pvsyst.com.

Dear Ishan,

Real sorry, your question is taking some time to answer. Unfortunately, there are some details that need to be understood. We are trying to provide as informed an answer as possible.

We should be able to reply by the end of the week.
