  1. Dear Vera, In your print screen, the bifacial module is not active as the green LED is not illuminated. Here is an example of the bifacial module in use: Regards,
  2. Dear Rohit Rana, Could you please send your project to our support email: support@pvsyst.com? We need to investigate why you are experiencing this issue. Regars,
  3. Dear Estagiario, In the 'System' window, there is a button labeled 'Single-Line Diagram' below. You can click on it to visualize. Regards, Muhammed Sarikaya
  4. Dear Muhammad, I think you haven't activated 'power sharing' because the buttons in the single-line diagram are not active. Could you please share a complete screenshot of your windows? That way, I can understand better why you're experiencing this problem. Regards,
  5. Dear Muhammad Faizen, The reason the SLB (Single Line Diagram) button is inactive is due to the illogical distribution of your modules across the MPPT (Maximum Power Point Tracking) inputs. You are attempting to distribute 7 strings across 5 MPPT inputs. While you can proceed with the simulation, you won't be able to open the "Single Line Diagram". Regards, Muhammed Sarikaya
  6. Dear Mohamed, You can conduct your project with the panels mounted on a fixed tilt plane. To enable bifacial calculations for a fixed structure system, activate the bifacial model and then select 'Use Unlimited Sheds 2D-Model'. Regards, Muhammed Sarikaya
  7. Hello, You can only choose from the available cable sections. I suggest selecting the highest section to simulate pessimistic results. Regards,
  8. Dear Somasekhar, Please read this help page of PVsyst: https://www.pvsyst.com/help/index.html?thermal_loss.htm You will understand the reasons behind the ability to decrease or increase the thermal loss factor. Furthermore, in our YouTube video tutorial, within the "Thermal Behavior" chapter, we explain how you can adjust this parameter. Regards, Muhammed Sarikaya
  9. Dear Mohsin, First of all, in PVsyst, azimuth 0° always represents the direction of the sun. In your case, when you input 180°, it means your PV modules are facing north. You mentioned having a roof with two different tilt angles, but you didn't specify the azimuth angles. Usually, when installing PV modules on a tilted roof with multiple orientations, you need to define both the tilt and azimuth angles of your roof. Additionally, in the system setup, you need to create two subarrays for each orientation. Here is an example with a screenshot: Please be cautious because the inverter you have selected have unbalanced MPPT (Maximum Power Point Tracking). You should configure the Main Input with a higher PV array capacity than the second input. You can check this in the two screenshots provided. If you have any question, don't esitate to write me. Regards, Muhammed
  10. Dear Georgy, I can't answer you because it depends on multiple variables. In PVsyst, you can't set different orientations within a series of modules. I suggest increasing the detailed losses for mismatch in your simulation. The idea is to simulate the worst-case scenario. That way, when you install your PV modules, the actual electrical production will likely be higher than the simulation. Regards, Muhammed Sarikaya
  11. Dear Vera, Today you can do this project separately by creating two distinct project. Regards, Muhammed Sarikaya
  12. Dear Michalis Angeli, You can mix only 2 orientations. Regards, Muhammed Sarikaya
  13. Dear Marcoz15 It's very simple; first, you need to select "Orientation" and choose the field type as "Several orientations," as shown in this image: Then, when configuring the system, there are a few things you need to be careful about: In the "List of subarrays," you should create two subarrays. When selecting your inverter, make sure it has a minimum of 2 MPPTs. Activate the multi-MPPT feature, and don't forget to assign the orientation for each subarray. Does that make it clearer? Regards, Muhammed Sarikaya
  14. Dear Mohamed, You can export your result with advanced simul. Click on advance simul. Click on Output File: Next, you need to select the name for your output file and confirm the simulation variables you want. In this same windows, you have to click on "Simulation" if you want to generate a csv file that can be opened in excel. Regards, Muhammed Sarikaya
  15. Dear Sama Ashraf, There is a procedure you have to follow in SketchUp before you import it into PVsyst. Please send us an email at support@pvsyst.com, and I will send you the tutorial PDF where we explain how to import a 3D scene from SketchUp. Regards, Muhammed Sarikaya
  16. Dear Waiphyo, You can simulate a single string in an inverter with 2 MPPT inputs. You can follow these steps: If you don't check the box "use multi-MPPT feature," it doesn't mean that the simulation will not find the maximum power of your PV array. PVsyst will always find the maximum power. In this situation, PVsyst will only use the power for the calculation and will not take into account the number of entries on your inverter. Regards, Muhammed Sarikaya
  17. Dear Aaron Polo Can you please tell me how you have defined your load profile in the button "user's needs"?
  18. Dear Nahel, Indeed, using millimeters might not be the best choice. Do you know which unit of measurement you are using in your 3D software for drawing your 3D scene project? Regards, Muhammed Sarikaya
  19. Dear Nihal Meena, Try changing the input size to millimeters, as the input size in your 3D software might not be set correctly. If you have any more questions, please don't hesitate to contact me. Regards, Muhammed Sarikaya
  20. Dear Andel In PVsyst, you can simulate an unlimited shed or unlimited trackers only with a bifacial system. Regards, Muhammed Sarikaya
  21. Dear Nikoloz, I'm sorry, but I can't provide an answer without more details about your project. Could you please share a screenshot of your system? Regards, Muhammed Sarikaya
  22. Dear Vera, This is precisely what you need to understand: For this inverter to function, there is a minimum voltage requirement. The 'operating voltage' range is listed as 684-1450 V. It's important to note that temperature affects voltage; the higher the temperature, the lower the voltage. That's why we base our calculations on a module temperature of 60°C. I suggest increasing the number of modules or opting for an inverter with less power. If you need any assistance, please don't hesitate to contact me. Regards, Muhammed Sarikaya
  23. Dear Michalis Angeli, This is not a problem with the trial version. You need to follow my tutorial precisely, as outlined below. To activate the button, click on the surface of your roof. After that, you can proceed with my tutorial. Regards, Muhammed Sarikaya
  24. Dear Michalis Angeli, I understand that creating your project in the 3D scene can be a bit challenging at times. Allow me to introduce another method for constructing your project. Here's how to do it: Right-click on the menu bar where "point of view" is located, and then click on "normal to face." This will reveal the "normal to face" button in the menu: Afterward, your 3D scene should be set to the realistic view for rendering. Following this, you need to click on the surface of your roof. In my example, I clicked on the left roof. To verify if the roof is selected, you'll notice that the color is slightly different from the rest of the building: After clicking on "normal to face" in the "point of view" menu, you'll notice that the view has changed to align with the normal of your selected face: Then, you can create a single PV table by using the "Draw" button located in the "Tools" menu. Following this, draw a rectangle of the size you desire on the surface of your roof. You can later modify the created zone to align with your table. To do this, double-click on the created zone table and make the necessary adjustments. You can also view in basic parameters to check the orientation of your table. If you require further assistance with this topic, please don't hesitate to reach out to me. Regards, Muhammed
  25. Dear Hrira, Please avoid adding too many details to the 3D scene as it makes the simulation more complex and increases the calculation time. For trees, you can easily incorporate a template that we provide into the 3D scene in PVsyst. Here, I'll demonstrate how to do it: In 3D scene, click on : - Create - Elementary shading object - And then select Tree in shape type Then you can modify the dimensions of the tree as you desire. Additionally, after adding it to your 3D scene, you can copy and paste it as many times as needed. If you require further assistance with this topic, please feel free to reach out to me. Regards, Muhammed Sarikaya
