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

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,

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

Dear Loïs, I invite you to read the FAQ section regarding this question: Regards, Muhammed Sarikaya

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

Dear Abeer, Your simulation may not perform well. It would be better to place the PV table above the topography. Regards, Muhammed Sarikaya

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

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

Dear Meurville, What is the purpose of restricting the inverter? Can you explain exactly what you want to do? Regards, Muhammed Sarikaya

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

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

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,

Dear Hampus, Unfortunately, we can't set default values for detailed losses and project settings. Regards,

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,

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

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

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

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

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

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

Dear Ben, First of all, in defining the water needs, you specified a maximum flow rate of 8 m³/h. However, the selected pump operates between 40 m³/h and 200 m³/h. Don't you think the pump is oversized for the well? Even if you install the pump at depth, the water availability won't change; the well's resources only allow for a flow rate of 8 m³/h maximum. In real operation, the pump will frequently start and stop because the water level will drop to the level of the pump, and a pump should never operate without water. I suggest you consider replacing this pump with one that has a lower flow rate, more suitable for the well's capacity. Regards, Muhammed Sarikaya

Dear Swonno, Unfortunately, it's an iterative process. You have to set it up independently, and there is no way to copy and simplify these things. Regards, Muhammed Sarikaya

Dear Swonnon, I don't understand exactly what you want to do. Can you provide more details? Regards, Muhammed Sarikaya

Dear Marc, The racking is not considered in the simulation calculations. Perhaps you are referring to changes in temperature depending on how it is mounted in your project. If this is the case, in the "Detailed Losses" window and under the "Thermal Parameters" tab, there are options for how your system is mounted. Please see the screenshot below: For more help on this topic, you can visit: https://www.pvsyst.com/help/thermal_loss.htm Regards, Muhammed Sarikaya

Dear Pontesimo, I invite you to watch our tutorial on how to create different sub-arrays and configure MPPT and power sharing. Regards, Muhammed Sarikaya
