Dear Ziad, Can you also try this feature: Tools → Automatic altitude (see below)? Select your entire table first, then enable this feature. On the right, try setting 1 meter or more, choose Lowest point, and click Set automatic altitude. Let me know if this solves your issue. Regards,

Dear, You can disable this check in Near Shadings by going to: Tools → Disable field interpenetration check See below: Regards,

Dear Sara, You need to adjust your PV area to make it 1,100 m², but you also need to know its position on the façade. At first, you have two orientations — one for the façade and one for the rooftop. So, you need to create two orientations, and in the system, create two sub-arrays where you can assign the appropriate PV modules for each orientation. Then, in the 3D scene, when you place the PV modules, you need to select the initial orientation. If the PV module brand or size is different, Near Shadings will automatically detect it. What’s important to know is that Near Shadings is used to calculate shading losses on your PV surface. Once calculated, it applies the percentage of shading losses to the final simulation results. Regards,

Dear Nikoloz, You can follow this tutorial: Regards,

Dear Ziad, Without the project, I can’t know what the issue is. Could you please send us your project at support@pvsyst.com and explain what the issue is? Regards, Muhammed Sarikaya

Dear Johan, From your error message, we can see that the 3D scene is larger than the declared system. I noticed that you are changing the number of trackers in batch mode, while also modifying the number of strings in parallel. There is a workaround to make this work: In PVsyst, go to Settings → Edit advanced parameters. In the search box, type “area”, then adjust the parameter as highlighted below. Regards,

Dear Zahra, If you know the exact global wiring resistance of your system and want a precise result, you can fill in the field "Global wiring resistance". Usually, the value for "Loss fraction at STC" is used when the exact global wiring resistance is unknown and you are just estimating it based on the STC value. For module losses: LID losses: Not applicable for PV modules based on n-dop wafers. You need to know the technology used in your PV module. Otherwise, we don’t have precise information regarding LID losses, since manufacturers don’t usually share this type of data. You can decide to add 1% or 2% depending on your confidence in the PV module. See our help page: https://www.pvsyst.com/help/project-design/array-and-system-losses/lid-loss.html Module Quality: Please read our help page: https://www.pvsyst.com/help/project-design/array-and-system-losses/module-quality-losses.html Module Mismatch Losses: Please also see our help page: https://www.pvsyst.com/help/project-design/array-and-system-losses/array-mismatch-losses/index.html Usually, this is also an approximation, based on your assessment of the PV module quality and the variability between them. Regards,

Dear Caio, Thank you for the suggestion. I will add it to our software development roadmap, but I can't guarantee when this feature will be implemented. Regards, Muhammed Sarikaya

Dear Caio, Thank you for your suggestion to improve the 3D feature in PVsyst. For your first suggestion, I recommend trying the “Pen – Extruded polygon” tool (see below). It lets you draw a complex shape on the ground plane and extrude it to whatever height you need. Let me know if this helps. Regards, Muhammed Sarikaya

Dear Zahra, For a stand-alone project, which is generally small and simple, we don’t represent the inverter, because the main focus is to understand how the PV modules, along with the batteries, will meet the users’ electricity needs. This is why it’s not possible to define an inverter with specific parameters for each MPPT in such a project. For your first question: No, this is not possible in PVsyst. The software does not allow you to input pre-calculated PV production as an input. In a stand-alone system, you must define the PV fields, and PVsyst will calculate the production based on those components. For your second question: Could you tell me which parameter you would like to modify? Regards,

Dear Oscar First of all, in the "unlimited shed" orientation, the sensitive width is the total width of the modules aligned on your PV table. For example, if your PV module is positioned in landscape in your 3D scene, the smaller side is 1.134 meters. Since you want two rows placed one above the other in each table (still in landscape), you need to multiply the smaller length by 2: 1.134 × 2 = 2.268 meters. In my example below, I used 2 meters as the sensitive width. You can always verify in the 3D scene whether the sensitive width value is correct. But if you already know the dimensions of your PV module, its orientation (landscape or portrait), and the number of rows per table, you can calculate the sensitive width. You can also click on the "Help" button in the "Show Optimization" window — it will open a help page with a full explanation (see below). If you need more information or something isn’t clear, don’t hesitate to reach out to us. Regards,

Dear Haseeb, Can you please send your project to support@pvsyst.com so that we can analyze the issue? Please follow this process to export your project as a ZIP file: Regards,

I invite you to consult our help page regarding this: https://www.pvsyst.com/help/project-design/shadings/near-shadings-3d-construction/construction-tools/zones-of-tables.html?h=zones+tables

Dear NFI, I don't understand what you mean by "one way to configure the string with inverters." I invite you to watch this tutorial, which explains well how to configure it: Regarding near shading, it can indeed be difficult to place the modules. I suggest trying the zone tools as well. Also, if you encounter an error message, please send it to us at support@pvsyst.com along with a screenshot, so we can help you solve the problem. Regards,

Dear Shivam The map size is limited, but if you want to import an image, you can do the following: Take a screenshot of a satellite image. Then import it via File > Import > Import a ground image. Finally, you need to scale the image to match the actual scale. To crop an imported image: Double-click on the image. You will see "Ground Image" with a Crop option (highlighted at the bottom right). Click on it to crop and resize the image. Regards,
