  1. Dear Shivam Pandey, It depends on you. How did you import or create the horizon line? If you imported it from Meteonorm or PVGIS, the horizon is reliable, and you can use it for your simulation. Regards, Muhammed Sarikaya
  2. Dear Irakli, PVsyst is not responsible for the actions of its users, and we do not verify whether the results are accurate. We can only investigate in the event of a bug to determine its cause. Additionally, I should mention that the azimuth in your projects appears to be incorrect. Please be aware that an azimuth of 0 in PVsyst corresponds to the direction of the sun. Regards, Muhammed Sarikaya
  3. Dear MEURVILLE, You must folow this model : You must use the names 'Date,' 'Load,' and '[W]' at the top of the cells so that PVsyst can accept this load profile. Regards, Muhammed Sarikaya
  4. Dear Panagiota, You can only define losses for MV (medium voltage) transformers and HV (high voltage) transformers. Regards, Muhammed Sarikaya
  5. Dear Giulio, Unfortenately, we can't see results for every single inverter or subarray. Regards, Muhammed Sarikaya
  6. Dear Sir, We update the database using the requests of the manufacturers, and publish it with each new issue of PVsyst. We can't of course follow all the new products of all manufacturers in the world. We don't want to include data without the acknowledgement of the manufacturer. Nevertheless you can easily create your own components by yourself. The easiest way is to choose a similar existing device in the database, modify its parameters according to the manufacturer's datasheets, and save it under a new name, therefore creating a new file in your database. You have a tutorial for that on youtube: https://www.youtube.com/c/PVsystTutos, page Component database Additionally, I invite you to read this page on how to determine IAM values And how to establish pan file: Regards, Muhammed Sarikaya
  7. 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,
  8. 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,
  9. 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
  10. 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,
  11. 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
  12. 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
  13. Hello, You can only choose from the available cable sections. I suggest selecting the highest section to simulate pessimistic results. Regards,
  14. 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
  15. 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
  16. 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
  17. Dear Vera, Today you can do this project separately by creating two distinct project. Regards, Muhammed Sarikaya
  18. Dear Michalis Angeli, You can mix only 2 orientations. Regards, Muhammed Sarikaya
  19. 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
  20. 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
  21. 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
  22. 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
  23. Dear Aaron Polo Can you please tell me how you have defined your load profile in the button "user's needs"?
  24. 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
  25. 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
