Dear Swonno, Can you explain what "origin feature in 3D scene" means? Also, could you share how you placed your PV tables and what type of tables you are using? In PVsyst, under Tools, there is an automatic altitude feature, but it works well only if all the tables are independent from each other. Regards,

Dear Johnny, First of all, in a self-consumption + storage system, the system responds to the user's load. So, if you have a small load profile and a large PV system, excess energy will be injected into the grid. Since I don’t know your exact goal, I suggest creating multiple variants — starting with fewer PV modules, then trying with higher storage capacity. This will give you different results and help you find the best configuration. Regards,

Dear Stewart, In the Near Shading tool, you need to draw your 3D scene manually — it is not generated automatically. I suggest watching our tutorial related to near shadings: Regards

Dear, See my example below on how to proceed: Click Orientation Management: Then, select the orientation you want to delete and delete it, as shown below: Regards,

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. Regards,

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. Regards,

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. Regards,

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. Regards,

Dear Bommu, Please send us an email to support regarding this project. Regards,

Dear NGS, Could you please send your project by email to support@pvsyst.com and explain what you are trying to do? Regards,

Dear, Indeed, both of your options provide good results. Thank you for the advice. I will take note of it in our roadmap. Regards,

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. Regards,

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. Regards,

Dear Afshin, It's not possible to do that. Regards,

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. Regards,

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. Regards,

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. Regards,

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,

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° Regards,

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 Regards,

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

Dear Bruno, Can you please send us your project at support@pvsyst.com with a detailed message explaining your issue? Regards,

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. Regards,

Dear Emi, It's difficult for me to assess and assist you with your simulation. Could you please send me your project at support@pvsyst.com? Regards,

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. Regards,
