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,

PVsyst String Configuration and Shading Scene Simulation Issues.

PVsyst String Configuration and Shading Scene Simulation Issues.
Muhammed Sarikaya replied to NFI's topic in Simulations
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,

Dear Greg, If you don’t want to import energy from the grid, it’s considered a stand-alone project. I suggest running your simulation as a stand-alone system. In a grid-connected project, the grid supplies energy when the system can’t meet the user’s demand. See my screenshot below: Regards,

Shading forest for utility projects
Muhammed Sarikaya replied to CarlosSolis's topic in Shadings and tracking
Dear Carlos, I don’t recommend importing a detailed 3D forest file into PVsyst. The more detailed the 3D scene is, the longer it takes to calculate the shading impact on the PV tables. For the horizon line, you can already import the mountain line in PVsyst using the horizon feature. In the 3D scene, if there is a forest at the edge of your terrain, I suggest drawing a wall to represent the last row of trees. Regards, -
Inverter output power by .OND file

Dear Andrés, Can you please send us your .ond file at support@pvsyst.com so we can examine it? Also, could you explain your issue in your email? Regards, -
Midday spike in shading loss
Muhammed Sarikaya replied to Alex Stark's topic in Shadings and tracking
Dear Alex, Is it possible for you to send us your project at support@pvsyst.com so we can test it and compare the results between V7 and V8? In your email, could you also explain the procedure you followed that led to these differences? Regards, -
Dear Nikoloz, It seems that the inverter you want to use is a central inverter with only one MPPT. This means all strings connected to it must be identical. So, you don’t need to worry about the MPPT definition. In PVsyst, just select the configuration “PNom sharing within the inverter” (see below). Then, you only need to specify the number of inverters. Regards,
