[Backtracking at different Phi min and Phi max]

These seem logical when with backtracking have worst results

The backtracking even at -45/45 seem to have better energy production results than no backtracking

So the backtracking changes the tracking angle to avoid shading

Taking into account that the Dimention and string configuration does not change when using -55/55 backtracking you will have shading too and the backtracking will correct the tracking angle.

The potition that with backtracking have not no shadings shouldn't be the same for -45/45 and -55/55 . So I had considered that actually this two different options make the same rotation withbacktracking.

What am I soosing?

[Hay and Perez model In Pv Syst 6.41]

Now I am using Pv Syst 6.41

I am trying to an existing variant run with Perez model to run alternatevely with Hay model. Althou I change in Preference > Physical models the report still mentions Perez and the result does not change.

Do I have to try something else ?

I checked in 6.39 again and I had no problem chamging the model.

[Free meteo Data - Realistic]

From the free Databases that are provided from different sources are released in the NET which are supposed to be more reliable ?

This differs from Area to area - Europem - America - Asia

I am more interested in MENA countries

[Backtracking at different Phi min and Phi max]

I have ctreated a tracking system Tilted that is moving from East to West

I have compared backtracking vs backtracking and backtracking (Phi min -45 Phi max 45) seems to have more Yield

I have compared backtracking (Phi min -45 Phi max 45) and backtracking (Phi min -55 Phi max 55) and the -55/55 seems to have better results. Is this feasible ?

I had in my mind that as the backtracking is more productive at -45/45 the -55/55 should give same results as the tracking angle in order to avoid shading should not be different

[More simulation variants]

In Pv syst we can save simulation variants from VC0 to CV9 and from VC1 to VCZ meaning totally 36 variants.

Is there any way to save more than 36 variants?

[Limiting Power injected to Grid]

We want to simulate a Project with nominal capacity of inverters (Power AC) 58MW, while the maximum power AC that can be injected to national grid is 50MW. Is it possible to fix this in PVsyst 6.3.0 and in which way?
