[Handling Tilt in Orientation and Near Shading Scene in PVSyst for Undulating Terrain]

Dear Andrés,

You can use the "Zone Tool" — see below how to access it:

Then, you can draw a zone where you place PV tables that follow the topography.

[DJI Terra and PVsyst]

Dear Nikoloz,

You have to find a way to extract the three coordinate points (X, Y, and Z) of your 3D object and save them as a CSV file. This way, PVsyst will accept the CSV file as topography.

[Mistake in documentation]

Dear Laura,

Thank you for reaching out to us.

First of all, we will replace "Ageing" with "Aging."

Regarding the manufacturer's lower limit guarantee, you can see it clearly in the graph below:

The sentence states that the module warranty represents the lower limit in reference to this graph, where it shows the loss of efficiency. It compares the black curve, which represents the module warranty, with the calculated aging curve, showing that the warranty curve has a higher efficiency loss than the calculated degradation.

Therefore, the sentence in the help documentation is correct in relation to this graph.

[2 Orientations in PVsyst]

Dear Emily,

I don't understand what you mean by "how can I assign specific modules from the 3D model to these two orientations."

I also don't understand how you can have 3,480 strings in one orientation and 699 strings in the other when you have defined a total of 35 strings. You must distribute the 35 strings between the two orientations.

I don't know how you defined the 3D scene, but you need to check which modules correspond to which orientation. PVsyst will automatically assign the number of modules based on the orientations you have defined.

Indeed, both of your options provide good results.

Thank you for the advice. I will take note of it in our roadmap.

[Different strings in the same inverter Pnom sharing]

Dear Alejandro,

Unfortunately, what you are trying to do is not possible.

Maybe you can approximate it by having the last two strings with the same number of modules in series.

Dear Alejandro,

In the advanced parameters, you need to type "spread" in the search bar. See below:

 

You can modify these parameters and increase their values.

Dear Afshin,

It's not  possible to do that.

Dear Zoe,

In the system section, you need to create a sub-array for the second orientation and define it. It is also important to assign it to the second orientation.

[Bifacial simulation]

Dear Bakhtiyar,

This parameter is a threshold for the RMS value of the pitch distribution that PVsyst finds in the 3D drawing.

The bifacial models in PVsyst are an approximation that is valid for identical long rows with constant pitch (spacing). If the simulation uses a 3D drawing of the PV system, then PVsyst will check if this drawing comes close to this idealization. For this purpose, it will calculate the RMS of the pitch distribution, and if it finds a value larger than the threshold, it will issue an error message, and the simulation will not be possible.

The default value of 0.1 m is not based on a specific study. The error message is meant to remind the user that the system which is being simulated, is not fully compatible with the idealized assumptions, and therefore an additional uncertainty of the bifacial contribution in the simulation results is to be expected.

So far there is no study that quantifies the increase of uncertainty in the simulation results as a function of the RMS of the pitch distribution. It will become possible to address this, once we have a more sophisticated bifacial model, which will be based on the 3D drawing. This is in work and will still require several months of development.

Dear Bakhtiyar,

 

Go to "Settings - Edit Advanced Parameters" as shown below:

Then, in the search box, type "bifacial" and modify the highlighted parameter as shown:

This modification should resolve your issue.

[Program acceleration]

Dear Bakhtiyar,

 

Avoid adding too much detail to the 3D scene in SketchUp. You need to create a simple 3D scene—only this way can help resolve your freezing issue.

Alternatively, you can upgrade your computer's performance to handle the detailed 3D scene.

Regards,

[Error: angle between the field and the average orientation is too high.]

Dear, 

Try increasing this parameter as well:

Go to "Settings - Edit advanced parameters."

 

• Type "spread" in the search box.
• It will display multiple parameters—increase all of them to 90°

[Defining PV tables in 3D scene which with unequal number of modules on each row]

Dear James,

 

With bifacial modules, we can create projects with multiple orientations in the 3D scene. However, you must meet certain conditions:

The PV tables must have the same width.
The pitch between rows must be uniform.
All PV tables must be identical.

See the helps: https://www.pvsyst.com/help/project-design/bifacial-systems/2d-bifacial-model-conditions.html

Dear Yildirim,

 

In "Edit Advanced Parameters," try modifying the following three highlighted parameters to 90°.

[Module Overlapping Issue in PVsyst When Using Zone Function on Uneven Terrain]

Dear Swonno

This is a check to avoid interpenetration between the PV object and other objects, such as the ground. If part of the PV module is inside another object, that part will be completely shaded.

Therefore, you should avoid placing it too close to other objects as much as possible.

When using zone tools, you can determine the distance from the ground. If you set it to at least 1 meter above the topography, you shouldn't receive an error message indicating that your PV modules are too close to an object.

[3D scene]

Dear Vasil,

 

Depending on your project, you can add more PV modules in the 3D scene, but they must correspond to your "Orientation #1." PVsyst will then automatically match the final surface area of this orientation between the system definition and the 3D scene definition.

[Enedis impose le Cos Phi à 0.94 sur les onduleurs]

Bonjour,

Vous faites certainement référence à l'injection dans le réseau avec un facteur de puissance.

Pour cela, allez dans "Gestion de l'énergie", puis dans l'onglet "Facteur de puissance".

Il est important de savoir si votre onduleur injecte du réactif dans le réseau. Selon le cas, vous devrez préciser s'il s'agit d'un facteur de puissance en retard ou en avance. Je vous conseille de consulter l’aide à ce sujet : https://www.pvsyst.com/help/project-design/grid-connected-system-definition/power-factor/index.html?h=power+factor

 

Cordialement,

Dear Caner,

[add new hybrid inverter]

Dear,

 

Hybrid inverters are indeed not taken into account in PVsyst. However, you can run a simulation with storage by defining the self-consumption profile. This simulation will show the energy balance, including the energy injected into the grid, the energy stored in the battery, and the energy used by the user.

I invite you to watch our tutorials explaining how to perform this type of simulation:
