  1. Dear Stephen, Yes, it's possible to use both versions on the same computer. Regards, Muhammed Sarikaya
  2. Dear Dany, In stand-alone design, it is not possible to remove the batteries. Regards,
  3. Dear Swonno, You can modify the limit parameter to allow PVsyst to run the simulation. Got to "Settings-Edit advanced parameters" In the search box, type "inverter" and find the line "The Inverter power is strongly oversized." Adjust the ratio to, for example, 0.1 as follows: This will enable you to run your simulation. Don’t hesitate to reach out to us if you have any questions. Regards, Muhammed Sarikaya
  4. Dear Swonno, From SketchUp, it's important to assign a material to the surface of the PV module. You can also assign a material named 'ground' to it in SketchUp. Then, when you import into PVsyst, you must define what is a PV object by checking the box corresponding to the material name, and what is a terrain object by selecting the box with the associated name. I invite you to read our tutorial on this topic. Here's how you can find it: Regards, Muhammed Sarikaya
  5. Dear Valerie Unfortenately it's not possible to do this. Regards, Muhammed Sarikaya
  6. Dear Aidenn, It's likely because you forgot to enable an option in PVcase. You need to import the PVcase layout with the 'Terrain-following trackers' option enabled. This will break the layout into smaller trackers for PVsyst to account for motor and joint gaps. You should consult the PVcase help section and search for 'TFT' to find the procedure to follow. Regards, Muhammed Sarikaya
  7. First of all, I need to understand whether you have a PV table or just a single PV module. Could you please share your DAE file with us at support@pvsyst.com for further investigation? This will help us identify where the issues are. Regards,
  8. Dear Jig, I invite you to read about the topic of albedo at: https://www.pvsyst.com/help/albedo.htm And about the topic of soiling at: https://www.pvsyst.com/help/soiling_loss.htm Regards, Muhammed Sarikaya
  9. Dear Loïs, I invite you to read the FAQ section regarding this question: Regards, Muhammed Sarikaya
  10. Dear Aidenn, For this value, leave the module quality box checked to use the manufacturer's specifications. Then, the three other values will never appear on the datasheet. It depends on your decision. Please click on the question mark next to each definition for more information. Regards, Muhammed Sarikaya
  11. Dear Abeer, Your simulation may not perform well. It would be better to place the PV table above the topography. Regards, Muhammed Sarikaya
  12. Dear Jonasf, I don't understand "simulate failure of a device." What do you mean by this? Indeed, for a standalone project, there is no "unavailability period." You can't import a custom Earray into PVsyst; the software is based on weather data and calculates from this with PV modules. When importing weather data into PVsyst, the software controls it to check if it is realistic or not. This is why you get the error message. It's possible to modify some advanced parameters for limit conditions like what you are trying to do. Go to "Settings - Edit Advanced Parameters." Then, put "clearness" in the search box. You will see two limit parameters that you can modify. Try to decrease the first parameter and increase the second. Tell me if you succeed and don't hesitate to reach out to us for more precision. Regards, Muhammed Sarikaya
  13. Dear Abeer, I invite you to watch this tutorial for a more detailed explanation: There is a workaround: in the shading window, go to "Tools > List and Management of Objects." Then, change all the baseline slopes to 0, as shown below: However, your PV array will not automatically adjust to the terrain; they will all have different heights. Try this and let me know if you succeed. Regards, Muhammed Sarikaya
  14. Dear Meurville, What is the purpose of restricting the inverter? Can you explain exactly what you want to do? Regards, Muhammed Sarikaya
  15. Dear Abeer, I imagine you set the orientation angle at 25 degrees, which will remain the same. Then, in the 3D scene, you can add the slope, and for the simulation, the final orientation with the slope added will be used. Could you provide more details about your question? A screenshot would also help me answer you more precisely. Regards, Muhammed Sarikaya
  16. Dear Carlos, I can't see the step where you define the power sharing, so I assume that you have mastered the subject. I can suggest the following steps for the 40 kW inverter with 4 MPPTs: First inverter input: connect 2 strings Second inverter input: connect 1 string Third inverter input: connect 1 string Fourth inverter input: connect 1 string This requires you to create 4 sub-arrays where you define the previous inputs. That means you will have: Sub-array 1: 2 strings Sub-array 2: 1 string Sub-array 3: 1 string Sub-array 4: 1 string This method will allow you to create and use power sharing effectively. If you need more help, don't hesitate to reach out to us. Regards, Muhammed Sarikaya
  17. Dear Hampus, You can create a basic variant, and then for each new project, you can import this variant by clicking on 'Import,' as shown below: Regards,
  18. Dear Hampus, Unfortunately, we can't set default values for detailed losses and project settings. Regards,
  19. Dear Pranav, I don’t understand your project. Could you provide more details about what you intend to do? What is the purpose of having a battery if you don’t use the energy yourself? Does your system inject energy into the grid? If that is the case, why do you need batteries if you can inject all the produced energy directly into the grid? Regards,
  20. Dear Abeer, In the near shading feature, you can define the topography which has a slope, and then use the 'zone tool' feature to define the position of the PV modules on your terrain. Be careful, as a 4 MW project will require significant computational power and can take a long time to simulate. If you need more precision, don't hesitate to post your question here. Regards, Muhammed Sarikaya
  21. Dear Vasyl, You can adjust this parameter to ensure a lower temperature. Click in "Project settings" Then modify this value: Please don't hesitate to reach out if you need further assistance. Regards, Muhammed Sarikaya
  22. Dear Zwonno, I invite you to check out our tutorial on orientation management and base slope: You need to match the PV array with the orientation of the nearby shading scene in the system. Regards, Muhammed Sarikaya
  23. Dear Ranjit, It's possible that you didn't activate the bifacial module. Please follow this tutorial to learn how to use a bifacial PV module: Regards, Muhammed Sarikaya
  24. Dear Swonno, Even if it's an ellipse, you can reduce the 'aperture angle,' which will allow you to draw something close to an ellipse. Remember, it's not necessary to create a perfect 3D scene. You are trying to understand the shading effect on your PV array, and a perfect and precise rooftop definition will probably not make a big difference compared to an approximate rooftop definition. Regards, Muhammed Sarikaya
  25. Dear Swonno, I suggest using the "near shading" feature with the elementary object "portion of cylinder." Here's an example: You should adjust the "aperture angle" to match your project's requirements. Regards, Muhammed Sarikaya
